<p>In Uganda’s Kibale National Park, scientists have spent years doing the slow, unglamorous work of catching tiny wasps. The payoff is big: a clearer map of “dark biodiversity” - the vast share of species that are poorly known or not yet described - and practical clues for how to protect it before it disappears.</p>



<p>Most of Earth’s species have never been formally documented, making them easy to overlook in conservation plans. Biologists call these overlooked lineages “dark taxa.” They are especially abundant in tropical forests, where species, habitats, and ecological roles remain thinly studied.</p>



<p>The Biodiversity Unit at the <a href="https://www.utu.fi/en" target="_blank" rel="noreferrer noopener">University of Turku</a> has made a specialty of unveiling this hidden diversity, describing new species each year, and building tools to slow global biodiversity loss.</p>



<h2 class="wp-block-heading" id="h-a-living-lab-for-biodiversity">A living lab for biodiversity</h2>



<p>Kibale National Park offers a mosaic of habitats. These include tracts of largely undisturbed forest, areas recovering from past logging, and nearby farmland. That patchwork allowed researchers to ask a simple but powerful question: where, exactly, is the unknown diversity concentrated?</p>



<p>The team focused on ichneumonid <a href="https://www.earth.com/news/invasive-parasitic-wasps-quietly-crossed-oceans-now-thriving-in-u-s-oak-trees/">wasps</a> - one of the most diverse animal groups on the planet - and, within it, the subfamily Pimplinae.</p>



<p>These wasps don’t just buzz around flowers. They regulate other species by parasitizing the immature stages of insects and <a href="https://www.earth.com/news/fossil-with-spiders-brain-suggests-arachnids-originated-in-the-sea/">spiders</a>, linking them tightly to the health of entire food webs.</p>



<p>“Ichneumonids are a very poorly known taxon in Africa - we estimate that over half of the species we found are new to science,” said doctoral researcher Emil Österman. </p>



<p>With so little baseline knowledge for tropical ichneumonids, the team used long-term, standardized sampling to see how Pimplinae diversity is distributed across Kibale’s different habitats.</p>



<h2 class="wp-block-heading" id="h-wasps-link-species-and-ecosystems">Wasps link species and ecosystems</h2>



<p>Because parasitoid wasps sit high in food webs, they are sensitive to disruptions below them. If the insects and spiders they rely on decline, parasitoids tend to follow. </p>



<p>That sensitivity makes Pimplinae useful indicators: shifts in their richness and abundance often mirror broader changes in biodiversity. The new work confirms what many ecologists have suspected but struggled to quantify in tropical Africa. </p>



<p>“Many of our finds weren't unexpected, but we didn't have data based on long-term collecting in the field," said Tapani Hopkins, a researcher with the Biodiversity Unit. </p>



<p>"Now we can tell in greater detail how many more <a href="https://www.earth.com/news/new-owl-species-discovered-in-africa/">species</a> there are in natural forest, and to what extent disturbed or logged tropical forest can harbor species.”</p>



<h2 class="wp-block-heading" id="h-farmland-cannot-match-forest-life">Farmland cannot match forest life</h2>



<p>The headline result is encouraging for conservation: intact forest in Kibale harbors especially rich Pimplinae communities. Secondary forest that is regrowing after logging also supports far more species than adjacent farmland.</p>



<p>In other words, protecting remaining forest is essential, and letting disturbed forest recover pays real biodiversity dividends.</p>



<p>“Our results clearly show that African forest, including forest that is recovering from <a href="https://www.earth.com/news/rainforests-replanted-seedlings-after-logging-do-not-recover-well/">logging</a>, maintains a species-rich Pimplinae fauna compared to, say, nearby farmland," Österman said. "Species-rich habitats can be considered especially valuable in conserving unknown dark biodiversity.” </p>



<p>That matters for policy and on-the-ground management. If you want to safeguard the most unknown species, prioritize forests - and don’t write off recovering stands. They’re already doing important work.</p>



<h2 class="wp-block-heading" id="h-global-forests-store-hidden-diversity">Global forests store hidden diversity</h2>



<p>The team also asked a bigger biogeographic question: how does African tropical diversity stack up against the New World? </p>



<p>Drawing on their parallel long-term collections in western Amazonia and Brazil’s coastal forests, the researchers found hints that South American rainforests may host even higher Pimplinae richness than Africa. However, African forests still harbor a rich fauna.</p>



<p>“Conserving dark taxa effectively requires a detailed knowledge of how biodiversity is distributed, both locally and at a global scale,” said Professor Ilari E. Sääksjärvi, who leads the Biodiversity Unit.</p>



<p>The comparison underscores a simple lesson: tropical forests on multiple continents are irreplaceable reservoirs of poorly known life.</p>



<h2 class="wp-block-heading" id="h-forest-biodiversity-loss-accelerates">Forest biodiversity loss accelerates</h2>



<p>Parasitoid wasps are only one window into dark biodiversity. But they tell a familiar story: clearing or simplifying forests causes losses to ripple upward. Protecting or allowing forests to recover lets complex communities rebound - including species we haven’t named yet.</p>



<p>The Kibale study shows <a href="https://www.earth.com/news/biodiversity-leaks-conservation-efforts-may-shift-harm-elsewhere/">conservation</a> can succeed despite limited taxonomy: protect habitats that concentrate hidden diversity. It also highlights the value of patient, long-term fieldwork in places where biodiversity is vanishing fastest.</p>



<p>“We will continue our field studies at different tropical forest sites, because that is where biodiversity is disappearing especially quickly. It is a fight against time. When a rainforest is destroyed, we lose countless species which we know nothing about,” Sääksjärvi concluded.</p>

Wasps shine a light on 'dark biodiversity' in rainforests

In Uganda’s Kibale National Park, scientists have spent years doing the slow, unglamorous work of catching tiny wasps. The payoff is big: a clearer map of “dark biodiversity” - the vast share of species that are poorly known or not yet described - and practical clues for how to protect it before it disappears. Most of Earth’s species have never been formally documented, making them easy to overlook in conservation plans. Biologists call these overlooked lineages “dark taxa.” They are especially abundant in tropical forests, where species,...

<p>Bird populations depend on a stable food supply, especially during breeding seasons when their energy needs are highest. Insect-eating birds rely on various prey, but moths play a particularly important role in some regions. </p>



<p>A recent study explored how fluctuations in moth abundance influence bird populations across Finland. Researchers found that this relationship varies by region, with northern areas showing a stronger connection between <a href="https://www.earth.com/news/moth-makes-its-flat-wings-appear-3d-to-trick-predators/" target="_blank" rel="noreferrer noopener">moth numbers</a> and bird abundance.</p>



<p>By analyzing long-term data, scientists uncovered patterns that highlight how changes in insect populations might affect bird survival and reproduction. </p>



<p>These findings provide valuable insights into broader ecological dynamics, reinforcing concerns about the cascading effects of insect declines.</p>



<h2 class="wp-block-heading" id="h-early-season-moths-and-bird-abundance">Early-season moths and bird abundance</h2>



<p>The study revealed a clear link between birds that depend on caterpillars and the abundance of moths that overwinter as eggs or adults. </p>



<p>These early-season moths provide a crucial food source for many resident and long-distance migratory forest birds during their breeding period. </p>



<p>The strongest connection was observed in the north-boreal zone, where early-season moth populations had a noticeable impact on <a href="https://www.earth.com/news/natures-defense-against-the-invasive-spongy-moth-is-fading/" target="_blank" rel="noreferrer noopener">bird numbers</a>.</p>



<p>Birds in these regions rely heavily on insect prey during spring, and any fluctuations in moth populations can significantly influence bird abundance. </p>



<p>The results suggest that if insect populations decline, birds that rely on these food sources could face serious challenges.</p>



<p>The study emphasizes how environmental conditions shape species interactions, reinforcing the idea that changes in one part of the ecosystem can have far-reaching effects.</p>



<h2 class="wp-block-heading" id="h-northern-birds-depend-more-on-moths">Northern birds depend more on moths</h2>



<p>One of the key findings of the study was the regional variation in the moth-bird <a href="https://www.earth.com/news/bird-extinctions-shatter-the-harmonious-balance-of-nature/" target="_blank" rel="noreferrer noopener">relationship</a>. </p>



<p>While a strong connection was evident in the north, the same dependency was not found in southern and central Finland. Researchers believe that environmental differences explain this pattern.</p>



<p>“The reason why moth abundance affected bird abundance only in northern Finland is that, in the north, bird breeding seasons are short, food webs are relatively simple, and temporal moth abundance fluctuations from year to year are naturally strong,<em>"</em> explained Mahtab Yazdanian, the lead author and a doctoral researcher at the <a href="https://www.oulu.fi/en" target="_blank" rel="noreferrer noopener">University of Oulu</a>.</p>



<p>"Therefore, abundance changes of a particular group of insect prey more likely reflect in bird abundance in northern Finland than in central or southern Finland." </p>



<p>In other words, birds in the north are more reliant on moth preys compared to birds in the central and southern regions of Finland.</p>



<p>This explanation highlights how ecological conditions shape species interactions. In the north, birds have fewer alternative food sources, and their breeding seasons are tightly linked to the availability of moths. </p>



<p>As a result, any fluctuations in moth numbers directly affect bird populations, making them more vulnerable to environmental changes.</p>



<h2 class="wp-block-heading" id="h-bird-moth-connection">Bird-moth connection</h2>



<p>One of the most valuable aspects of the study was its use of long-term monitoring data. Spanning 26 years, the dataset provided a unique opportunity to examine patterns that might not be visible in short-term studies.</p>



<p>“This study highlights the value of long-term monitoring programmes. We are fortunate in Finland to have detailed abundance data for both moths and birds, which our study combines in full for the first time,” explained Tuomas Kankaanpää, a postdoctoral researcher at the University of Oulu.</p>



<p>Long-term datasets are rare in ecological research, yet they are essential for understanding complex interactions in natural ecosystems. </p>



<p>Without sustained monitoring efforts, it would be nearly impossible to detect gradual shifts in <a href="https://www.earth.com/news/city-moths-develop-smaller-wings-survive-light-pollution/" target="_blank" rel="noreferrer noopener">species</a> populations or identify key factors influencing their survival.</p>



<h2 class="wp-block-heading" id="h-complexity-of-food-webs">Complexity of food webs</h2>



<p>The study also sheds light on the challenges of studying ecosystem dynamics. Understanding how fluctuations in insect populations influence birds is difficult because natural environments are shaped by multiple interacting factors.</p>



<p>“Complexities in the ecosystem, the food web, and the insect populations' fluctuations have cascading effects on higher trophic levels like birds that are really difficult to systematically study in nature, where everything affects everything,” Yazdanian commented.</p>



<p>Finland’s exceptional long-term monitoring programs provided valuable data on nearly 80 bird species and 400 moth species dating back to 1993. </p>



<p>These datasets allow researchers to track ecological changes over time, offering insights that would otherwise be impossible to obtain.</p>



<p>The study highlights how detailed monitoring can help identify critical patterns in species interactions, ultimately contributing to better conservation strategies.</p>



<h2 class="wp-block-heading" id="h-future-research-and-conservation-efforts">Future research and conservation efforts</h2>



<p>The study’s findings highlight the urgent need for continued research on how insect declines affect bird populations. </p>



<p>Insect populations worldwide face threats from habitat loss, climate change, and pollution, and it is essential to understand how these changes impact animals that are at higher levels in the food web.</p>



<p>Ongoing research at the University of Oulu aims to pinpoint which moth species are most important as food sources for different bird species. </p>



<p>Advances in DNA meta-barcoding technology are helping researchers analyze bird diets more accurately. </p>



<p>By identifying multiple species from mixed samples, scientists can gain a deeper understanding of the specific relationships between birds and their <a href="https://www.earth.com/news/birds-are-moving-north-and-breeding-earlier-in-a-changing-climate/" target="_blank" rel="noreferrer noopener">insect</a> prey.</p>



<h2 class="wp-block-heading" id="h-conservation-strategies">Conservation strategies</h2>



<p>The results of this study have significant implications for conservation efforts. Declining insect populations not only threaten biodiversity but also disrupt entire food webs. </p>



<p>By considering the entire food web, conservation strategies can be more effective in protecting bird populations. </p>



<p>Supporting insect diversity through <a href="https://www.earth.com/news/are-we-failing-the-worlds-most-threatened-species/" target="_blank" rel="noreferrer noopener">habitat conservation</a> and sustainable land-use practices will help maintain the delicate balance between species.</p>



<p>Protecting natural ecosystems requires a comprehensive approach that takes into account both the direct and indirect effects of environmental change.</p>



<h2 class="wp-block-heading" id="h-a-collaborative-research-effort">A collaborative research effort</h2>



<p>The study was led by the University of Oulu and brought together experts from multiple institutions.</p>



<p>Their combined expertise played a crucial role in uncovering new insights into the relationship between moths and birds.</p>



<p>As researchers continue to investigate these complex ecological interactions, studies like this will provide valuable knowledge for conservation efforts. </p>



<p>Understanding the intricate connections between species helps ensure that both birds and their <a href="https://www.earth.com/news/moths-may-struggle-to-move-in-response-to-climate-change/" target="_blank" rel="noreferrer noopener">insect</a> prey can thrive in a rapidly changing world.</p>

Birds communities struggle as moth populations decline

Bird populations depend on a stable food supply, especially during...

<p>Smartphones have become essential in daily life, offering convenience and instant access to information. They connect people across the world, enable remote work, and provide entertainment at the touch of a button. </p>



<p>However, as reliance on these devices grows, concerns are raised about the impact of smartphones on mental health.</p>



<p>A study by the <a href="https://www.pewresearch.org" target="_blank" rel="noreferrer noopener">Pew Research Center</a> revealed that 91% of Americans own a smartphone with internet access. This figure has surged from just one-third in 2011.</p>



<p>Another study showed that people spend an average of five hours and sixteen minutes daily on their phones. This prolonged screen time raises important questions about its effects on attention spans, social interactions, and emotional health.</p>



<p>A recent Gallup Poll found that 58% of Americans worry about <a href="https://www.earth.com/news/teens-with-problematic-smartphone-use-suffer-from-depression/" target="_blank" rel="noreferrer noopener">excessive smartphone use</a>. Among those below the age of 30, this concern jumps to 80%. As digital consumption increases, researchers are investigating the long-term consequences of constant connectivity.</p>



<h2 class="wp-block-heading" id="h-too-much-mobile-internet">Too much mobile internet </h2>



<p>Mental health experts warn that excessive screen time may contribute to anxiety, depression, and cognitive overload. People often experience stress from continuous notifications, the pressure of social media, and the difficulty of focusing on real-world tasks.</p>



<p>New research led by Adrian Ward, associate professor of marketing at <a href="https://www.mccombs.utexas.edu" target="_blank" rel="noreferrer noopener">Texas McCombs</a>, examines these effects. His study explores whether blocking mobile internet access can improve psychological well-being. </p>



<p>The findings suggest that taking a break from constant <a href="https://www.earth.com/news/internet-addiction-impairs-brain-function-in-teenagers/" target="_blank" rel="noreferrer noopener">online engage</a><a href="https://www.earth.com/news/internet-addiction-impairs-brain-function-in-teenagers/">ment</a> has measurable benefits.</p>



<p>“Smartphones have drastically changed our lives and behaviors over the past 15 years, but our basic human psychology remains the same,” noted Ward. “Our big question was, are we adapted to deal with constant connection to everything all the time? The data suggest that we are not.”</p>



<p>Ward collaborated with experts in psychology, psychiatry, and consumer behavior. His research team included scholars from the <a href="https://www.ualberta.ca/en/index.html" target="_blank" rel="noreferrer noopener">University of Alberta</a>, Georgetown University, Boston University, and the University of British Columbia.</p>



<p>Their goal was to understand how disconnecting from mobile internet impacts attention, emotional health, and overall well-being.</p>



<h2 class="wp-block-heading" id="h-blocking-mobile-internet-for-two-weeks">Blocking mobile internet for two weeks</h2>



<p>The study followed 467 participants, with an average age of 32. The researchers asked them to install an app that blocked mobile internet access on their smartphones for a set period. The app restricted browsers and social media while still allowing calls and text messages.</p>



<p>Participants could access the internet through computers at work, school, or home, but they were no longer constantly connected on their phones. This intervention provided insight into whether limiting mobile internet in particular could enhance cognitive and <a href="https://www.earth.com/news/oxytocin-cuddle-hormone-fosters-love-boosts-memory-and-may-cure-addiction/" target="_blank" rel="noreferrer noopener">emotional health</a>.</p>



<p>To evaluate changes over time, researchers divided participants into two groups. One group blocked mobile internet for the first two weeks, then regained access. The other group started with normal phone use and blocked the internet in the final two weeks. </p>



<p>By measuring participants’ mental health and attention spans at different points, the researchers could assess the impact of temporary disconnection.</p>



<h2 class="wp-block-heading" id="h-surprising-improvements-in-mental-health">Surprising improvements in mental health</h2>



<p>The results showed that even a short break from mobile <a href="https://www.earth.com/news/brain-discovery-offers-hope-for-tackling-opioid-addiction/" target="_blank" rel="noreferrer noopener">internet</a> access led to significant benefits. Many participants reported feeling less stressed and more in control of their daily activities.</p>



<p>Ninety-one percent of participants showed improvement in at least one area of psychological well-being. More than seventy percent reported better mental health after the two-week break. The degree of improvement in depression symptoms exceeded results from multiple studies on antidepressant medications.</p>



<p>Attention spans also improved significantly. Researchers found that the positive effects were equivalent to reversing ten years of cognitive decline. This suggests that taking periodic breaks from mobile internet could help restore focus and cognitive function.</p>



<p>One of the most striking findings was that benefits continued to increase over time. Participants reported feeling better with each passing day of limited phone use. By the end of the two-week period, many described an improved sense of clarity and emotional stability.</p>



<h2 class="wp-block-heading" id="h-more-time-for-meaningful-activities">More time for meaningful activities</h2>



<p>Ward believes that the improvements in well-being were not just due to reduced screen time but also to changes in daily habits. When participants limited mobile internet access, they spent more time on offline activities.</p>



<p>“Rather than watching more TV or movies, they increased time spent in the offline world. That’s doing hobbies, talking to people face-to-face, or going out in nature. They got more sleep, felt more socially connected, and felt more in control of their own decisions,” said Ward.</p>



<p>Instead of scrolling endlessly on their phones, participants engaged in hobbies, spent time with family, and reconnected with their surroundings. </p>



<p>Many reported feeling more productive and present in their daily lives. They also experienced fewer distractions, which led to deeper, more meaningful conversations with others.</p>



<h2 class="wp-block-heading" id="h-implications-for-workplaces">Implications for workplaces</h2>



<p>The study highlights a growing demand for technology that promotes healthier digital habits. </p>



<p>Ward suggests that companies could design services that help users spend less time online rather than more. Subscription-based models, for instance, could reduce reliance on advertisements that encourage excessive screen time.</p>



<p>Employers could also explore digital wellness initiatives. Many workplaces already recognize the impact of screen fatigue on productivity and mental health. Companies might introduce tools that help employees balance their online and offline time, leading to better focus and job satisfaction.</p>



<p>However, Ward stresses the importance of making these programs voluntary. In the study, only 57% of participants installed the internet-blocking app, and just 25% completed the full two-week period. This suggests that not everyone is ready to disconnect entirely.</p>



<p>“Maybe you put it to a vote, and people will choose to vote for it,” said Ward. “The fact that 80% of people think they use their phones too much suggests that maybe they will.”</p>



<h2 class="wp-block-heading" id="h-rethinking-the-role-of-smartphones">Rethinking the role of smartphones</h2>



<p>While mobile technology has brought undeniable benefits, this study suggests that constant connectivity comes at a cost. </p>



<p>Many people feel overwhelmed by their devices but struggle to disconnect. Small changes, such as taking intentional breaks from mobile internet, could improve mental health and attention spans.</p>



<p>Ward’s research provides compelling evidence that stepping away from screens, even temporarily, allows people to regain control of their time and well-being. </p>



<p>As awareness grows, more individuals and businesses may seek solutions that promote a healthier balance between online and offline life.</p>



<p>The study is published in the journal <em><a href="https://academic.oup.com/pnasnexus/article/4/2/pgaf017/8016017" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.</em></p>

Taking a smartphone break can improve your life in surprising ways

Smartphones have become essential in daily life, offering convenience and...

<p>Plastic waste is one of the biggest threats to marine ecosystems today. Every year, millions of tons of plastic enter the ocean, creating massive pollution problems and killing marine organisms. This waste does not simply disappear.</p>



<p>Instead, it breaks down into microplastics, which spread through the water and harm marine life. Scientists have long searched for ways to reduce the <a href="https://www.earth.com/news/plastics-supercharge-toxin-absorption-in-plants-and-humans/" target="_blank" rel="noreferrer noopener">impact of plastic pollution</a>, but most existing solutions struggle to degrade plastic efficiently.</p>



<p>Now, researchers at the University of Hawai‘i (<a href="https://manoa.hawaii.edu" target="_blank" rel="noreferrer noopener">UH</a>) at Mānoa have made a remarkable discovery. They have identified marine fungi that are capable of breaking down plastic. Even more impressively, they found that some of these fungi can be "trained" to consume plastic faster.</p>



<p>The research could initiate new ways of cleaning up the ocean and tackling one of the most pressing environmental challenges of our time.</p>



<h2 class="wp-block-heading" id="h-plastic-waste-and-its-lasting-impact">Plastic waste and its lasting impact</h2>



<p>Plastics are widely used because they are durable, lightweight, and cheap. These same qualities, however, make them a persistent <a href="https://www.earth.com/news/plastic-particles-found-in-99-of-tested-seafood-samples/" target="_blank" rel="noreferrer noopener">environmental hazard</a>. </p>



<p>Unlike organic materials, plastic does not decompose naturally. Instead, sunlight, heat, and physical forces break it down into smaller pieces. These microplastics then spread throughout the ocean, entering the food chain and accumulating in marine organisms.</p>



<p>Plastics can also release harmful chemicals, such as phthalates and bisphenol A, which disrupt marine ecosystems. Animals often mistake plastic for food, and its ingestion leads to malnutrition and starvation.</p>



<p>With an estimated 1,051,200 garbage trucks' worth of plastic entering the ocean each year, finding a way to eliminate this pollution is crucial.</p>



<h2 class="wp-block-heading" id="h-untapped-potential-of-marine-fungi">Untapped potential of marine fungi</h2>



<p>“Plastic in the environment today is extremely long-lived, and is nearly impossible to degrade using existing technologies,” said Ronja Steinbach, who led this research as a marine biology undergraduate student in the UH Mānoa <a href="https://natsci.manoa.hawaii.edu" target="_blank" rel="noreferrer noopener">College of Natural Sciences</a>. </p>



<p>“Our research highlights marine fungi as a promising and largely untapped group to investigate for new ways to recycle and remove plastic from nature. Very few people study fungi in the ocean, and we estimated that fewer than one percent of marine fungi are currently described."</p>



<p>Fungi are known for their ability to break down tough organic materials. Many species can digest substances that other organisms cannot, such as wood and chitin. </p>



<p>However, most studies on fungi and <a href="https://www.earth.com/news/plastic-treaty-is-a-historic-opportunity-to-stop-a-human-health-crisis/" target="_blank" rel="noreferrer noopener">plastic</a> degradation have focused on land-based species. The UH Mānoa team wanted to see if marine fungi had similar capabilities.</p>



<h2 class="wp-block-heading" id="h-testing-marine-fungi-for-plastic-degradation">Testing marine fungi for plastic degradation</h2>



<p>The researchers collected fungi from various sources, including sand, seaweed, corals, and sponges in Hawai‘i’s nearshore waters. </p>



<p>They then tested these fungi to see if they could break down plastic, specifically polyurethane, a common material found in foams, adhesives, and medical products.</p>



<p>“Fungi possess a superpower for eating things that other organisms can’t digest (like wood, or chitin), so we tested the fungi in our collection for their ability to digest plastic,” said Professor Anthony Amend from Pacific Biosciences Research Center. </p>



<p>Professor Amend heads up the lab where Steinbach conducted the research with marine biology graduate studen Syrena Whitner.</p>



<p>The researchers placed polyurethane in petri dishes - along with various types of fungi - and observed their interactions. Some fungi showed a clear ability to degrade the <a href="https://www.earth.com/news/scientists-discover-how-microplastics-accumulate-in-coral-reefs/" target="_blank" rel="noreferrer noopener">plastic</a>.</p>



<p>The team then took the fastest-growing fungi and exposed them to polyurethane over time to see if they could evolve to consume plastic even more efficiently.</p>



<h2 class="wp-block-heading" id="h-marine-fungi-show-rapid-adaptation">Marine fungi show rapid adaptation</h2>



<p>The results of the experiment were astonishing. The fungi adapted quickly, with some increasing their feeding rates by 15% within just three months.</p>



<p>“We were shocked to find that more than 60% of the fungi we collected from the ocean had some ability to eat plastic and transform it into fungi,” said Steinbach. </p>



<p>“We were also impressed to see how quickly fungi were able to adapt. It was very exciting to see that in just three months, a relatively short amount of time, some of the fungi were able to increase their feeding rates by as much as 15%.”</p>



<p>The findings suggest that marine fungi could play a significant role in breaking down plastic pollution. The speed at which some fungi adapted to eating plastic also raises hopes that further research could enhance their efficiency even more.</p>



<h2 class="wp-block-heading" id="h-hawaii-s-unique-role-in-plastic-research">Hawaii’s unique role in plastic research</h2>



<p>Hawaii’s location in the North Pacific Subtropical Gyre makes it a prime spot for studying plastic pollution. Ocean currents bring plastic waste from all over the world to Hawai‘i’s shores.</p>



<p>Nearby, the Great Pacific Garbage Patch contains massive amounts of plastic debris, making it a major environmental concern.</p>



<p>Because of this, Hawaii serves as an ideal natural laboratory for researching plastic degradation. </p>



<p>The fungi collected from these waters may have evolved unique abilities to break down plastic due to their constant exposure to pollution. This makes them valuable candidates for future biotechnological applications.</p>



<h2 class="wp-block-heading" id="h-expanding-the-research">Expanding the research</h2>



<p>The UH Mānoa team is now looking to expand their research. They want to test whether these fungi can degrade other plastics, such as polyethylene and polyethylene terephthalate. </p>



<p>These materials are even more resistant to decomposition and are some of the most common plastics found in the ocean.</p>



<p>Additionally, scientists are working to understand the molecular mechanisms behind fungi’s ability to break down plastic. By studying these processes at a cellular level, they hope to improve plastic degradation techniques.</p>



<p>The next step is to collaborate with other experts to develop practical solutions based on these findings.</p>



<p>“We hope to collaborate with engineers, chemists, and oceanographers who can leverage these findings into actual solutions to clean up our beaches and oceans,” said Steinbach.</p>



<p>If scientists can refine these fungal processes, they could potentially be used on a larger scale. Marine fungi could become a key tool for reducing <a href="https://www.earth.com/news/plastic-pollution-is-changing-the-entire-earth-system/" target="_blank" rel="noreferrer noopener">plastic waste</a>, both in the ocean and on land.</p>

Marine fungi can be trained to degrade plastic pollution

Plastic waste is one of the biggest threats to marine...

<p>Bird evolution has taken a remarkable turn with the discovery of two ancient fossils from a species named <em>Baminornis zhenghensis</em>, which lived in what is now southeast China's Fujian Province.</p>



<p>Dated to approximately 149 million years ago, these Jurassic-era fossils provide crucial insights into the early diversification of birds. </p>



<p>The fossils were unearthed by a team of scientists from the Institute of Vertebrate Paleontology and Paleoanthropology <a href="http://english.ivpp.cas.cn/" target="_blank" rel="noreferrer noopener">(IVPP)</a> of the Chinese Academy of Sciences, which is a leading institution in paleontological research.</p>



<p>Spearheading the study was Professor Wang Min, whose work continues to reshape our understanding of avian ancestry.</p>



<h2 class="wp-block-heading" id="h-bird-evolution-theory-the-basics">Bird evolution theory - the basics</h2>



<p>The current leading theory on bird evolution says that modern birds evolved from small, feathered theropod dinosaurs - yep, the same group that includes <em><a href="https://www.earth.com/news/t-rex-was-about-70-percent-bigger-than-we-thought/" target="_blank" rel="noreferrer noopener">T. rex</a></em>.</p>



<p>Scientists believe that around 150 million years ago, some of these dinosaurs developed feathers not just for warmth but also for gliding and eventually powered flight. </p>



<p>The famous <em>Archaeopteryx</em>, often called the "first bird," had both dinosaur-like traits (teeth, claws, and a long bony tail) and bird-like features (feathers and wings). </p>



<p>Over millions of years, these early birds became lighter, developed better flying skills, and adapted to different environments, eventually giving rise to the diverse bird species we see today.</p>



<h2 class="wp-block-heading" id="h-from-the-shadows-of-archaeopteryx">From the shadows of <em>Archaeopteryx</em></h2>



<p><em><a href="https://www.earth.com/news/chinese-fossil-provides-a-new-glimpse-into-early-bird-evolution/" target="_blank" rel="noreferrer noopener">Archaeopteryx</a></em>, despite its feathered wings, bears close resemblance to non-avialan <a href="https://www.earth.com/news/dinosaurs-were-going-strong-when-the-deadly-asteroid-struck/" target="_blank" rel="noreferrer noopener">dinosaurs</a>.</p>



<p>Notably, this is due to its distinctively long reptilian tail - a vivid departure from the short-tailed morphology observed in modern and <a href="https://www.earth.com/news/oldest-known-bird-footprints-discovered-in-australia/" target="_blank" rel="noreferrer noopener">Cretaceous birds</a>.</p>



<p>Reflecting on the classification of <em>Archaeopteryx</em>, recent studies have placed it as a deinonychosaurian dinosaur, a sister group to birds.</p>



<p>This brings up an intriguing question: Do we have any definitive records of Jurassic birds?</p>



<h2 class="wp-block-heading" id="h-meet-baminornis-zhenghensis">Meet <em>Baminornis zhenghensis</em></h2>



<p>This is where the new discovery steps in. Among the two fossils found in Fujian Province, the team named one <em>Baminornis zhenghensis</em>. </p>



<p>This fossil exhibits an exclusive set of features: the shoulder and pelvic girdles resemble ornithothoracine birds, and there is an early-stage hand structure similar to that found in non-avialan dinosaurs.</p>



<p>Perhaps a standout feature of <em>Baminornis zhenghensis</em> is its short tail that ends in a compound bone called the pygostyle, a feature that is also prominent in <a href="https://www.earth.com/news/modern-bird-skulls-retain-some-dinosaur-traits/" target="_blank" rel="noreferrer noopener">contemporary birds</a>.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/02/bird-evolution_Baminornis-zhenghensis-species_timeline-pushed-back_credit-Zhao-Chuang_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/02/bird-evolution_Baminornis-zhenghensis-species_timeline-pushed-back_credit-Zhao-Chuang_1s.webp" alt="Life reconstruction of the Jurassic bird Baminornis zhenghensis from the Zhenghe Fauna.

Credit: Zhao Chuang</em></figcaption></figure>



<p>"Previously, the oldest record of short-tailed birds is from the Early Cretaceous. <em>Baminornis zhenghensis</em> is the sole Jurassic and the oldest short-tailed bird yet discovered, pushing back the appearance of this derived bird feature by nearly 20 million years," Prof. Wang stated.</p>



<h2 class="wp-block-heading" id="h-bridging-a-large-gap-in-bird-evolution">Bridging a large gap in bird evolution</h2>



<p>What makes this discovery so intriguing? </p>



<p>These fossils present compelling evidence that birds began diversifying much earlier than previously thought.</p>



<p>Typically, Earth's most diverse group of terrestrial vertebrates - birds, are believed to have <a href="https://www.earth.com/news/chinese-fossil-provides-a-new-glimpse-into-early-bird-evolution/">diversified </a>during the Jurassic period. </p>



<p>But the details of this diversification were shrouded in mystery due to a significant shortage of tangible fossil records.</p>



<p>Until now, the only widely accepted Jurassic bird was <em>Archaeopteryx</em>.</p>



<h2 class="wp-block-heading" id="h-baminornis-zhenghensis-an-early-bird"><em>Baminornis zhenghensis</em>: An early bird</h2>



<p>To fully understand the positioning of <em>Baminornis zhenghensis</em> in the bird evolution tree, the research team utilized several investigative methods.</p>



<p>The results indicated that this bird had evolved from <em>Archaeopteryx,</em> making it one of the oldest birds ever found.</p>



<p>"If we take a step back, and reconsider the phylogenetic uncertainty of Archaeopteryx, we do not doubt that <em>Baminornis zhenghensis</em> is the true Jurassic bird," Dr. Zhou Zhonghe, a co-author of the study, stated confidently </p>



<p>The second fossil is far from complete and consists solely of a furcula (a bone in the chest of birds). </p>



<p>Despite its poor preservation, the team remains hopeful that it might help in establishing the evolutionary link between non-avialan and avialan theropods.</p>



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



<p>The researchers revealed that the results of the analyses support that this furcula belonged to a member of the Ornithuromorpha, a diverse set of Cretaceous birds.</p>



<p>Yet, given its preserved state, they refrained from naming a new species based on this single bone.</p>



<p>In conclusion, this discovery, might not have answered all the questions regarding bird evolution, but it surely has opened up a new arena for possibilities and future discoveries. </p>



<p>Supporting the importance of fossils in piecing together the past, these artifacts from the Jurassic era have given us a glimpse into the true evolutionary journey of birds.</p>



<h2 class="wp-block-heading" id="h-baminornis-zhenghensis-and-bird-evolution"><em>Baminornis zhenghensis</em> and bird evolution</h2>



<p>The discovery of <em>Baminornis zhenghensis</em> provides compelling evidence that bird evolution was already well underway by the late Jurassic period.</p>



<p>By bridging a crucial gap in the fossil record, these newly unearthed fossils reshape our understanding of how early <a href="https://www.earth.com/news/birds-have-adapted-to-human-activities-for-thousands-of-years/" target="_blank" rel="noreferrer noopener">birds diversified and adapted</a>. </p>



<p>Scientists believe that such findings will continue to refine the evolutionary timeline, revealing more about the structural transformations that led to modern avian species. </p>



<p>Future excavations may yet unveil more missing pieces in the intricate puzzle of bird evolution.</p>



<p>The full study was published in the journal <em><a href="https://www.nature.com/articles/s41586-024-08410-z" target="_blank" rel="noreferrer noopener">Nature</a></em>.</p>

Bird evolution timeline pushed back at least 20 million years by new discovery

Bird evolution has taken a remarkable turn with the discovery...

<p>The universe is full of wonders, but few are as mesmerizing as the unpredictable brilliance of a supermassive black hole. At the core of the Milky Way, 26,000 light-years from Earth, Sagittarius A* flickers and flares in an ongoing celestial performance. </p>



<p>Unlike the serene darkness often associated with black holes, this one is anything but silent.</p>



<p>Imagine a disco ball in deep space, radiating bursts of energy <a href="https://www.earth.com/news/evidence-of-massive-early-universe-black-hole-stuns-astronomers/" target="_blank" rel="noreferrer noopener">across the cosmos</a>. This cosmic dynamo produces rapid flashes, some lasting mere seconds, while others burn brightly for extended periods. </p>



<p>The black hole's flares, scattered across various timescales, are unlike anything astronomers expected to see.</p>



<p>Thanks to the <a href="https://science.nasa.gov/mission/webb/" target="_blank" rel="noreferrer noopener">James Webb Space Telescope</a>, researchers now have the clearest, longest look at this astonishing activity, which reveals a chaotic but fascinating pattern.</p>



<h2 class="wp-block-heading" id="h-mysterious-black-hole-flares">Mysterious black hole flares</h2>



<p>For decades, black holes have remained enigmatic, with their immense gravitational pull swallowing everything in their path.</p>



<p>Scientists have only been able to study them through indirect observations, such as the effects on nearby stars or the radiation emitted by heated gas falling into the abyss. </p>



<p>But now, with Webb’s Near-Infrared Camera (NIRCam), astrophysicists can witness Sagittarius A* in action like never before. </p>



<p>By peering deep into the heart of our galaxy, Webb has captured a continuous sequence of flares erupting from the&nbsp;black hole's&nbsp;surrounding accretion disk.</p>



<p>These flashes come in varying intensities, some as brief flickers and others as prolonged, blinding outbursts. What makes this discovery even more intriguing is the sheer unpredictability of the phenomenon.</p>



<h2 class="wp-block-heading" id="h-a-black-hole-that-never-rests">A black hole that never rests</h2>



<p>Farhad Yusef-Zadeh of <a href="https://www.northwestern.edu" target="_blank" rel="noreferrer noopener">Northwestern University</a>, who led the study, described the black hole’s activity as a constantly shifting display of light.</p>



<p>“In our data, we saw constantly changing, bubbling brightness,” said Yusef-Zadeh. “And then, boom! A big burst of brightness suddenly popped up. Then, it calmed down again."</p>



<p>"We couldn’t find a pattern in this activity. It appears to be random. The activity profile of this black hole was new and exciting every time that we looked at it.”</p>



<p>These findings paint a picture of a black hole that never rests. The accretion disk surrounding Sagittarius A* releases a steady stream of energy, creating a nonstop spectacle of fireworks. </p>



<h2 class="wp-block-heading" id="h-observing-an-unstable-giant">Observing an unstable giant</h2>



<p>The research team observed Sagittarius A* over the course of a year, totaling 48 hours of direct monitoring in eight- to ten-hour periods. This extensive observation time allowed them to track the <a href="https://www.earth.com/news/flares-shed-light-on-the-milky-ways-supermassive-black-hole/" target="_blank" rel="noreferrer noopener">black hole</a>’s behavior, and reveal its persistent, flaring activity.</p>



<p>The results exceeded expectations. While scientists predicted some level of flaring, the frequency and intensity of these bursts were surprising. </p>



<p>The accretion disk produces between five and six major flares each day, interspersed with smaller, unpredictable bursts. Some eruptions are faint and short-lived, while others shine with an intensity that outshines entire star systems.</p>



<h2 class="wp-block-heading" id="h-explaining-the-black-hole-s-flares">Explaining the black hole’s flares</h2>



<p>Despite this chaotic display, the researchers believe that two different processes are driving the black hole's flares. Smaller, short-lived bursts likely result from minor disturbances within the swirling accretion disk.</p>



<p>These disturbances cause pockets of plasma - hot, electrically charged gas - to become compressed, releasing short, sudden flashes of energy. Yusef-Zadeh compared this phenomenon to solar flares.</p>



<p>“It’s similar to how the Sun’s magnetic field gathers together, compresses, and then erupts a solar flare,” he explained. “Of course, the processes are more dramatic because the environment around a black hole is much more energetic and much more extreme. But the Sun’s surface also bubbles with activity.”</p>



<p>Meanwhile, the most powerful flares appear to be caused by magnetic reconnection events. These occur when tangled magnetic fields within the accretion disk snap and realign, unleashing massive amounts of energy.</p>



<p>“A magnetic reconnection event is like a spark of static electricity, which, in a sense, also is an ‘electric reconnection,’” noted Yusef-Zadeh.</p>



<h2 class="wp-block-heading" id="h-energy-loss-in-black-hole-flares">Energy loss in black hole flares</h2>



<p>One of the most intriguing discoveries from Webb’s observations was a subtle but important time delay in the&nbsp;black hole flares’ brightness. </p>



<p>Because <a href="https://science.nasa.gov/mission/webb/nircam/" target="_blank" rel="noreferrer noopener">NIRCam</a> can observe two wavelengths simultaneously - 2.1 and 4.8 microns - the scientists were able to compare how the flares changed over each wavelength.</p>



<p>They noticed something unexpected: events at the shorter wavelength consistently brightened before those at the longer wavelength. The delay ranged from just a few seconds to as long as 40 seconds.</p>



<p>“This is the first time we have seen a time delay in measurements at these wavelengths,” Yusef-Zadeh said. “We observed these wavelengths simultaneously with NIRCam and noticed the longer wavelength lags behind the shorter one by a very small amount.”</p>



<p>This delay offers crucial insight into the physical processes surrounding the <a href="https://www.earth.com/news/black-hole-draco-1es-1927-654-just-awoke-is-spewing-material-at-incredible-speeds/" target="_blank" rel="noreferrer noopener">black hole</a>. One possible explanation is that particles in the flare gradually lose energy over time, first dimming at shorter wavelengths before fading at longer wavelengths. </p>



<p>The findings suggest that the particles responsible for the emission are likely spiraling around magnetic field lines, and gradually radiating away their energy.</p>



<h2 class="wp-block-heading" id="h-looking-deeper-into-the-chaos">Looking deeper into the chaos</h2>



<p>To better understand Sagittarius A*, the research team hopes to conduct even longer observations in the future. They aim to observe the black hole continuously for 24 hours, reducing interference from background noise and allowing for an even clearer picture of the activity.</p>



<p>“If we can observe for 24 hours, then we can reduce the noise to see features that we were unable to see before. That would be amazing. We also can see if these flares repeat themselves or if they are truly random,” enthused Yusef-Zadeh.</p>



<p>By extending the observation period, researchers hope to answer critical questions: Do these&nbsp;black hole&nbsp;flares follow a hidden pattern? Are there external factors influencing the frequency of eruptions? Or is this randomness a fundamental characteristic of the black hole itself?</p>



<h2 class="wp-block-heading" id="h-a-window-into-the-unknown">A window into the unknown</h2>



<p>Sagittarius A* continues to challenge scientists’ understanding of black holes and their behavior. The James Webb Space Telescope is providing an unprecedented view into the heart of our galaxy, offering new perspectives on the processes that govern these mysterious cosmic entities.</p>



<p>This international collaboration, led by NASA in partnership with <a href="https://www.esa.int" target="_blank" rel="noreferrer noopener">ESA</a> and CSA, is not just revealing secrets about our own galaxy but is also shedding light on the nature of <a href="https://www.earth.com/news/understanding-x-ray-radiation-that-spews-out-of-black-holes-surroundings/" target="_blank" rel="noreferrer noopener">black holes</a> across the universe.</p>



<p>The Milky Way’s central black hole may remain unpredictable, but thanks to cutting-edge technology and persistent observation, its cosmic fireworks are no longer hidden in the shadows.</p>



<p>The study was published in <em><a href="https://www.researchgate.net/publication/387862936_Non-stop_Variability_of_Sgr_A_using_JWST_at_21_and_48_micron_Wavelengths_Evidence_for_Distinct_Populations_of_Faint_and_Bright_Variable_Emission">The Astrophysical Journal Letters</a></em>.</p>

Milky Way’s black hole unleashes mysterious flares

The universe is full of wonders, but few are as...

<p>Brake pad emissions have become a powerful but unsuspected source of air pollution, with recent studies revealing their possible health hazards.</p>



<p>Although diesel car emissions are well documented as harmful, a recent study has exposed an equally disturbing problem - the toxicity of brake pad dust.</p>



<h2 class="wp-block-heading" id="h-understanding-brake-pads-the-basics">Understanding brake pads - the basics</h2>



<p>Brake pads are the unsung heroes of your car’s braking system. Every time you press the brake pedal, these small but mighty components create the friction needed to slow you down. </p>



<p>They press against the brake rotor (or disc), generating enough resistance to stop the wheels from spinning. Over time, that constant friction wears them down, which is why you eventually need to replace them. </p>



<p>Not all brake pads are the same, though. Some are made from organic materials like rubber and glass, while others use semi-metallic or ceramic compounds for better performance and durability.</p>



<p>Some brake pads contain copper, because it's great at dissipating heat and reducing brake fade. This is why manufacturers have traditionally included it in semi-metallic and ceramic brake pads, and it's also why brake pads cause <a href="https://www.earth.com/news/auto-emission-climate-policies-save-children-boost-economies/" target="_blank" rel="noreferrer noopener">environmental harm</a>.</p>



<h2 class="wp-block-heading" id="h-copper-in-brake-pads">Copper in brake pads</h2>



<p>Researchers from the <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> (UK) performed a comprehensive study that targeted microscopic particles that are released from different types of brake pads.</p>



<p>What they discovered was remarkable: some brake pads release particles that are more toxic than those contained in diesel exhaust.</p>



<p>Researchers determined the prime culprit for this toxicity - high concentrations of copper in some brake pads.</p>



<p>These small particles, when breathed in, can travel deep into the lungs, injuring sensitive cells and possibly leading to severe health consequences.</p>



<h2 class="wp-block-heading" id="h-non-exhaust-auto-emissions">"Non-exhaust" auto emissions</h2>



<p>Although the risks of <a href="https://www.earth.com/news/epa-set-to-implement-unprecedented-auto-pollution-limits/" target="_blank" rel="noreferrer noopener">pollution from vehicles</a> are widely recognized, attention has commonly centered on exhaust emissions. </p>



<p>Tires, road, and brake pad wear particles are usually not considered as sources of emissions, and the pollution arising from these factors is not monitored or regulated.</p>



<p>Now, these "non-exhaust" emissions have become the leading contributor to vehicle-related particulate matter (PM) in the U.K. and parts of Europe.</p>



<p>Among them, brake dust stands out as a major offender.</p>



<h2 class="wp-block-heading" id="h-hidden-pollution-from-electric-cars">Hidden pollution from electric cars</h2>



<p>Lead author of the study, Dr. James Parkin, pointed out that the shift toward electric cars is pushing this problem into the limelight. </p>



<p>"People generally associate pollution from cars as being from exhaust pipes and think of <a href="https://www.earth.com/news/hidden-costs-electric-vehicle-tires-emit-20-more-pollution/" target="_blank" rel="noreferrer noopener">electric vehicles</a> as having zero emissions. However, EVs still produce particulate matter due to friction and wear of the road, tires, and brakes," Dr. Parkin explained.</p>



<p>“We wanted to understand how different types of chemical composition of pads affect the toxicity of the particles emitted and what this might mean for the health of individuals.”</p>



<h2 class="wp-block-heading" id="h-impact-of-pm2-5-on-human-lungs">Impact of PM2.5 on human lungs</h2>



<p>The focus of this study was on the presence of the smallest particles, PM2.5 and below, which are 30 times smaller than the diameter of a human hair.</p>



<p>These tiny particles can pass beyond the upper respiratory tract and penetrate into the thin air sacs in the lungs, where the exchange of oxygen and carbon dioxide takes place.</p>



<p>These fine particles from various sources are linked with more than four million premature deaths per year worldwide.</p>



<h2 class="wp-block-heading" id="h-identifying-the-most-toxic-brake-pads">Identifying the most toxic brake pads</h2>



<p>The researchers used special apparatus to collect brake pad <a href="https://www.earth.com/news/breast-cancer-incidence-linked-to-high-particulate-air-pollution/" target="_blank" rel="noreferrer noopener">particulate matter</a>. </p>



<p>The team then used lab samples of human lung cells and exposed them to this particulate matter to measure the effects, including inflammation and cell death.</p>



<p>The experiment showed that, of the four brake pad types tested (low metallic, semi-metallic, non-asbestos organic, and hybrid-ceramic), the non-asbestos organic pads were the most harmful.</p>



<p>They triggered inflammation and toxicity markers, making them more harmful to human lung cells than diesel exhaust particles.</p>



<p>Ceramic pads were the second most toxic. Interestingly, both non-asbestos organic and ceramic pads contain high concentrations of copper, and subsequent experiments with the copper removed found the particulate matter to be less <a href="https://www.earth.com/news/car-tires-shed-pollutants-that-are-especially-toxic-for-humans-and-wildlife/" target="_blank" rel="noreferrer noopener">toxic</a>.</p>



<h2 class="wp-block-heading" id="h-reducing-copper-used-in-auto-parts">Reducing copper used in auto parts</h2>



<p>The team's findings, published in the journal <em>Particle and Fibre Toxicology</em>, suggest reducing <a href="https://www.earth.com/news/copper-industry-of-king-solomons-era-didnt-harm-the-environment/" target="_blank" rel="noreferrer noopener">copper</a> content in brake pads could help alleviate some of the harmful effects of vehicle particulate matter.</p>



<p>"This research has important implications for health and future policy because, as we switch from diesel and petrol-powered cars to electric vehicles, non-exhaust particle emissions will remain," project supervisor Professor Matthew Loxham noted.</p>



<p>"Non-exhaust emissions could increase over time due to electric vehicles being heavier than combustion engine vehicles and creating greater friction," </p>



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



<p>As we approach an increasingly electric vehicle-led future, it is imperative to recognize that while electric vehicles may not have <a href="https://www.earth.com/news/car-tires-shed-pollutants-that-are-especially-toxic-for-humans-and-wildlife/" target="_blank" rel="noreferrer noopener">exhaust emissions</a>, they are still far from being emission-free.</p>



<p>If we are to achieve a healthier future, we must look beyond exhaust emissions and deal with the increasing effect of non-exhaust pollutants.</p>



<p>Vehicle emission regulations need to evolve to address non-exhaust sources such as tire and brake wear, ensuring that air quality improvements keep pace with technological advancements.</p>



<p>Also, ongoing research into alternative materials for brake pads and new braking technologies, including regenerative braking, might go a long way toward minimizing particulate matter emissions.</p>



<p>Addressing these under-emphasized pollution sources can allow us to have a more complete strategy for cleaner air and healthier communities.</p>



<p>The full study was published in the journal <em><a href="https://particleandfibretoxicology.biomedcentral.com/articles/10.1186/s12989-024-00617-2" target="_blank" rel="noreferrer noopener">Particle and Fibre Toxicology</a></em>.</p>

Several auto parts create worse air pollution than exhaust fumes

Brake pad emissions have become a powerful but unsuspected source...

<p>Circadian rhythms have a profound impact on many aspects of our health, from sleep to metabolism.</p>



<p>The diet we establish in childhood and adolescence can lay the foundation for lifelong health, but weight gain and obesity are commonly blamed on poor diet and lack of exercise alone, without considering the impact of circadian rhythms.</p>



<p>New research indicates that when we eat is as critical as what we eat. Researchers are beginning to understand how our own biological clock controls hunger and fullness.</p>



<h2 class="wp-block-heading" id="h-the-body-clock-and-weight-gain">The body clock and weight gain</h2>



<p>A team of researchers from <a href="https://medical.brown.edu/" target="_blank" rel="noreferrer noopener">Warren Alpert</a> Medical School and Mass General Brigham set out to investigate the intricate relationship between circadian rhythms, metabolism, and overall health.   </p>



<p>The experts focused on adolescents, a group particularly susceptible to developing long-term health concerns based on their <a href="https://www.earth.com/news/eating-behavior-is-influenced-by-the-unconscious-mind/" target="_blank" rel="noreferrer noopener">eating behaviors</a>.</p>



<p>The researchers uncovered a correlation between overweight or obese adolescents' caloric consumption and the timing of their meals.</p>



<p>They found that youngsters with higher body-mass indexes tended to consume a larger portion of their daily <a href="https://www.earth.com/news/can-caloric-restriction-help-you-live-longer-its-complicated/" target="_blank" rel="noreferrer noopener">caloric intake</a> later in the day when compared to their peers with healthier weights.</p>



<p>Lead investigator Mary Carskadon, a professor of psychiatry and human behavior at Warren Alpert, shared her observations.</p>



<p>“The critical nature of adolescent development to set the stage for a lifetime of health highlights the need to understand the roles played by sleep/wake and circadian timing processes for eating behavior," said Carskadon.</p>



<p>"The knowledge gained here opens a door to potential interventions that can enhance teen health moving forward."</p>



<h2 class="wp-block-heading" id="h-circadian-rhythms-a-hidden-force-in-nutrition">Circadian rhythms: A hidden force in nutrition</h2>



<p>Our circadian system is essentially a network of countless "clocks" present in almost every part of our body. These clocks help us adapt to changing demands throughout the day and night.</p>



<p>However, this system varies from one person to another due to multiple factors including genetics, behavior, and environmental influences.</p>



<p>The uniqueness of this study, according to contributing author David Barker, lies in the precise measurement of food intake and the control of environmental and behavioral influences.</p>



<p>The study was carried out in a controlled environment, in the absence of any external time cues, to ensure  that the outcomes reflected only the circadian influences on eating behaviors.</p>



<h2 class="wp-block-heading" id="h-the-experiment-and-its-findings">The experiment and its findings</h2>



<p>A group of 51 volunteers, aged 12 to 18, participated in the study. They were divided into three groups based on their body mass indexes. </p>



<p>The experiment was designed to maintain a 28-hour sleep and wake cycle, slightly longer than a typical 24-hour day. </p>



<p>The teenagers lived in the same space for 11 days and 10 nights, under carefully managed light settings. Provided with six opportunities to eat at fixed times, they were free to consume as much as they wished.</p>



<p>The researchers monitored the food intake and caloric count closely. Interestingly, the results showed that those in the overweight or obese groups ate more of their daily calories in the afternoon and early evening, when compared with the participants in the healthy weight group.</p>



<p>This indicates that our inner biological clock greatly influences our <a href="https://www.earth.com/news/healthy-eating-patterns-lower-the-risk-of-cardiovascular-disease/" target="_blank" rel="noreferrer noopener">eating patterns</a>, and that the timing of eating may affect our tendency to gain weight.</p>



<p>Frank Scheer, director of the Medical Chronobiology Program at Brigham and Women’s Hospital, highlighted the significance of the study.</p>



<p>“This study is the first to demonstrate that food intake itself is regulated by our internal body clock,” said Scheer.</p>



<h2 class="wp-block-heading" id="h-harnessing-the-power-of-circadian-hythms">Harnessing the power of circadian hythms</h2>



<p>Carskadon believes that insights like these could be incredibly useful in designing weight management strategies for adolescents.</p>



<p>“For example, the influence of circadian timing could be influenced by excluding <a href="https://www.earth.com/news/how-the-color-of-light-impacts-our-internal-clocks-and-circadian-rhythms/" target="_blank" rel="noreferrer noopener">light</a> late in the day and enhancing bright light in the morning, especially while exercising. That might help pull the rhythms to a better place - and also create healthy habits,” she explained. </p>



<p>The research team plans to explore the connection between our circadian system, diet, and metabolism, and how this knowledge could potentially help design timed dietary interventions to promote healthier lifestyles.</p>



<p>By identifying the optimal windows for eating, based on individual circadian rhythms, future strategies could help curb <a href="https://www.earth.com/news/childhood-obesity-rates-spiked-during-the-pandemic/" target="_blank" rel="noreferrer noopener">obesity</a> risks before they take root.</p>



<p>The full study was published in the journal <em><a href="https://www.pnas.org/doi/10.1073/pnas.2407907122" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a></em>.</p>

When you eat matters as much as what you eat

Circadian rhythms have a profound impact on many aspects of...

<p>Where is all the water that might fill oceans on distant planets and moons? According to NASA, the forthcoming SPHEREx astrophysics mission will take stock of water’s cosmic origins by scanning the galaxy for hidden reservoirs.&nbsp;</p>



<p>Experts say this ambitious endeavor may help uncover how water, the key molecule for life, accumulates on interstellar dust grains in vast clouds of gas and dust.</p>



<p>Since every living organism on Earth needs <a href="https://www.earth.com/news/enough-water-to-fill-trillions-of-earths-oceans-found-circling-black-hole-quasar/" target="_blank" rel="noreferrer noopener">water</a> to survive, scientists searching for life outside of our solar system are frequently guided by the phrase "follow the water."</p>



<p>The SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer) <a href="https://www.jpl.nasa.gov/missions/spherex/" target="_blank" rel="noreferrer noopener">mission</a> is set to launch on Thursday, February 27 from the Vandenberg Space Force Base in California. The explorer will be launched on a SpaceX Falcon 9 rocket. </p>



<p>Then, SPHEREx will begin its hunt for water, carbon dioxide, carbon monoxide, and other basic ingredients for life.</p>



<h2 class="wp-block-heading" id="h-mapping-ice-within-molecular-clouds">Mapping ice within molecular clouds</h2>



<p>While there are no free-floating oceans in space, scientists have long suspected that frozen water - formed by bonding oxygen and hydrogen atoms on tiny dust grains - accounts for much of the universe’s water content.&nbsp;</p>



<p>This ice is believed to accumulate in molecular clouds, the giant swaths of gas and dust from which stars and planetary systems eventually emerge.</p>



<p>SPHEREx will systematically survey these molecular clouds, where newly forming stars and the disks of matter surrounding them often mask hidden ice. </p>



<p>By analyzing key infrared wavelengths, the telescope can detect how water and other molecules absorb passing starlight, leaving a signature in the spectral data.</p>



<p>Rather than producing standard 2D images, SPHEREx will gather 3D spectral information along each line of sight, enabling researchers to see how much ice is present at different depths in the cloud.&nbsp;</p>



<p>Over the course of more than 9 million observations, the mission will deliver the largest-ever inventory of <a href="https://www.earth.com/news/unbound-water-molecules-dangling-oh-discovered-interstellar-ice-jwst/" target="_blank" rel="noreferrer noopener">interstellar ice</a>, clarifying how environments in these clouds influence the abundance of water and other frozen compounds.</p>



<h2 class="wp-block-heading" id="h-where-is-the-missing-water">Where is the missing water?</h2>



<p>Scientists’ interest in interstellar water has been longstanding. Yet a puzzle emerged in 1998, when NASA launched the <a href="https://www.cfa.harvard.edu/facilities-technology/telescopes-instruments/submillimeter-wave-astronomy-satellite" target="_blank" rel="noreferrer noopener">Submillimeter Wave Astronomy Satellite</a> (SWAS) to look for gaseous water in molecular clouds.&nbsp;</p>



<p>SWAS detected far less water in gas form than predicted, raising the question: where was it hiding?</p>



<p>“We eventually realized that SWAS had detected gaseous water in thin layers near the surface of molecular clouds, suggesting that there might be a lot more water inside the clouds, locked up as ice,” said Gary Melnick, a senior astronomer at the <a href="https://www.cfa.harvard.edu/" target="_blank" rel="noreferrer noopener">Center for Astrophysics | Harvard &amp; Smithsonian</a> and a member of the SPHEREx science team.</p>



<p>SWAS also found less oxygen gas than expected, leading researchers to conclude that oxygen atoms had adhered to dust grains and combined with hydrogen to form water.&nbsp;</p>



<p>The clouds’ interiors shield these ices from harsh cosmic radiation, preventing them from breaking apart. SPHEREx’s highly sensitive survey will now reveal more precisely where ice begins to form and how these ices evolve when <a href="https://www.earth.com/news/new-molecule-detected-in-space-where-stars-are-born/" target="_blank" rel="noreferrer noopener">stars</a> are born.</p>



<h2 class="wp-block-heading" id="h-exposing-the-secrets-of-cosmic-water">Exposing the secrets of cosmic water</h2>



<p>SPHEREx excels at broad, large-scale mapping, while telescopes like NASA’s James Webb Space Telescope (JWST) specialize in zooming in on a much smaller area with greater sensitivity to certain wavelengths.&nbsp;</p>



<p>These complementary designs will allow SPHEREx to flag regions of high interest, which Webb can then examine in detail.</p>



<p>“If SPHEREx discovers a particularly intriguing location, Webb can study that target with higher spectral resolving power and in wavelengths that SPHEREx cannot detect,” Melnick said. “These two telescopes could form a highly effective partnership.”</p>



<p>By coupling SPHEREx’s panoramic survey with Webb’s close-up observations, scientists hope to piece together a comprehensive picture of how cosmic water emerges, accumulates, and ultimately finds its way onto forming planets and moons.</p>



<h2 class="wp-block-heading" id="h-tracing-water-s-cosmic-life-cycle">Tracing water’s cosmic life cycle </h2>



<p>The logic behind “follow the water” rests on the knowledge that all known life depends on liquid H₂O. If large amounts of water ice are identified in molecular clouds, that material likely feeds into protoplanetary disks, eventually supplying the water for oceans and lakes.&nbsp;</p>



<p>Thus, SPHEREx’s broad inventory may help confirm or refine theories on how water-rich worlds like Earth were assembled.</p>



<p>Although space telescopes such as NASA’s Spitzer and the retired Herschel have cataloged water and other compounds in select regions, SPHEREx will be the first mission to look for these ices at a truly galactic scale.&nbsp;</p>



<p>Melnick and his colleagues plan to incorporate SPHEREx’s findings into existing catalogs of stars and dust, clarifying how and where water is being replenished - or destroyed - in cosmic neighborhoods.</p>



<p>Ultimately, the results will speak not only to the matter of where water resides but also to how it journeys from the frozen interiors of molecular clouds to become part of a rocky planet. </p>



<p>By following water’s cosmic life cycle, SPHEREx could reveal the processes that made Earth’s oceans possible. It may also shed light on how these processes shaped the conditions for <a href="https://www.earth.com/news/dinosaurs-are-helping-astronomers-in-the-search-for-extraterrestrial-life/" target="_blank" rel="noreferrer noopener">life</a> on our planet, and perhaps on countless other worlds.</p>

SPHEREx will scan the galaxy to look for life's ingredients

Where is all the water that might fill oceans on...

<p>Dreams have fascinated humans for centuries, yet not everyone remembers them. Some wake up vividly recalling detailed dream sequences, while others struggle to remember anything at all. This difference in dream recall has long puzzled scientists, leading to various theories about its cause.</p>



<p>Some suggest personality traits or cognitive abilities play a role, while others believe <a href="https://www.earth.com/news/sleep-disruptions-could-signal-the-onset-of-alzheimers/" target="_blank" rel="noreferrer noopener">sleep quality</a> and external factors have a stronger impact. A new study from the IMT School for Advanced Studies Lucca has taken a closer look at this phenomenon.</p>



<p>The researchers aimed to uncover the key factors shaping dream recall and how individual differences in sleep and cognition affect this ability.</p>



<h2 class="wp-block-heading" id="h-the-mystery-of-dream-recall">The mystery of dream recall</h2>



<p>Researchers have debated for years whether certain groups recall dreams more easily. </p>



<p>Some studies indicate that women, younger individuals, and those who daydream frequently are more likely to remember their <a href="https://www.earth.com/news/how-do-dreams-influence-our-perceptions/" target="_blank" rel="noreferrer noopener">dreams</a>. However, other studies do not confirm these findings.</p>



<p>Some theories suggest cognitive abilities like memory and attention influence dream recall, but evidence remains inconsistent.</p>



<p>The COVID-19 pandemic reignited interest in this topic. Reports of increased dream recall emerged worldwide, sparking discussions about how stress, lifestyle changes, and sleep disturbances affected dreaming. </p>



<p>Scientists saw an opportunity to explore why some people recall dreams more easily than others and whether external conditions play a role.</p>



<h2 class="wp-block-heading" id="h-tracking-dreams-and-sleep">Tracking dreams and sleep</h2>



<p>To investigate this mystery, researchers from <a href="https://www.imtlucca.it" target="_blank" rel="noreferrer noopener">IMT School</a>, in collaboration with experts at the <a href="https://international.unicam.it" target="_blank" rel="noreferrer noopener">University of Camerino</a>, conducted an extensive study between 2020 and 2024.</p>



<p>The team recruited over 200 participants aged 18 to 70 and monitored their sleep and cognitive functions over 15 days. </p>



<p>The participants kept daily dream records, while the researchers used wearable devices and psychometric tests to track their sleep quality and <a href="https://www.earth.com/news/wake-up-in-your-dreams-exploring-the-world-of-lucid-dreaming-sleep-science/" target="_blank" rel="noreferrer noopener">mental activity</a>.</p>



<p>Each participant received a voice recorder and was instructed to report their dreams every morning upon waking. They noted whether they remembered dreaming, had a vague impression of dreaming without specific details, or recalled full dream sequences. </p>



<p>The actigraph, a sleep-monitoring wrist device, recorded sleep duration, efficiency, and disturbances. Additionally, the participants underwent psychological assessments to measure anxiety, memory, attention, and proneness to mind-wandering.</p>



<h2 class="wp-block-heading" id="h-light-sleepers-recall-more-dreams">Light sleepers recall more dreams</h2>



<p>Dream recall showed significant variation between participants, influenced by multiple factors. </p>



<p>Those with a positive attitude toward dreams and a strong tendency for mind-wandering reported better dream recall. The ability to shift attention away from external tasks and engage in internal reflections seemed to contribute to retaining dream memories.</p>



<p>Sleep patterns played a crucial role. Individuals who experienced longer periods of light sleep had a higher likelihood of waking with dream memories. </p>



<p>Younger participants reported better dream recall, while older individuals frequently experienced "white dreams" - a sensation of having dreamt without recalling any details. This suggests that <a href="https://www.earth.com/news/the-sleeping-brain-may-predict-future-experiences/" target="_blank" rel="noreferrer noopener">memory processes</a> related to dreaming may change with age.</p>



<h2 class="wp-block-heading" id="h-seasonal-differences-in-dream-recall">Seasonal differences in dream recall</h2>



<p>One of the study's surprising findings was the seasonal variation in dream recall. Participants reported recalling fewer dreams during winter compared to spring. </p>



<p>This indicates that environmental factors, such as changes in daylight exposure or circadian rhythms, might influence the ability to remember dreams.</p>



<p>The relationship between seasonal changes and sleep quality has been explored in past research, but its connection to dream recall remains largely unexplored. </p>



<p>This new finding suggests that shifts in light exposure and sleep duration throughout the year might affect how dreams are encoded into memory.</p>



<h2 class="wp-block-heading" id="h-role-of-cognition-and-attention">Role of cognition and attention</h2>



<p>Beyond sleep quality and external factors, cognitive abilities played a role in dream memory. Participants with better memory performance and selective attention reported stronger dream recall. </p>



<p>This supports the idea that remembering dreams is not just about the depth of sleep but also about how the brain processes and retains <a href="https://www.earth.com/news/whispered-dreams-how-relaxing-words-tune-our-heartbeat-to-sleep/" target="_blank" rel="noreferrer noopener">experiences</a> during the night.</p>



<p>The study also highlighted how emotional states and stress levels might impact dream recall. Participants with higher anxiety levels showed inconsistent dream recall patterns, suggesting that emotions can interfere with the ability to retain dream memories. </p>



<p>Further research could explore whether emotional regulation techniques influence how people remember their dreams.</p>



<h2 class="wp-block-heading" id="h-implications-of-the-study">Implications of the study</h2>



<p>“Our findings suggest that dream recall is not just a matter of chance but a reflection of how personal attitudes, cognitive traits, and sleep dynamics interact,” explained Giulio Bernardi, professor in general psychology at the IMT School.</p>



<p>“These insights not only deepen our understanding of the mechanisms behind dreaming but also have implications for exploring dreams' role in mental health and in the study of human consciousness.”</p>



<p>Valentina Elce, researcher at the IMT School and first author of the study, noted that data collected within this project will serve as a reference for future comparisons with clinical populations.</p>



<p>“This will allow us to move forward the research on the pathological alterations of dreaming and their potential prognostic and diagnostic value," said Elce. </p>



<h2 class="wp-block-heading" id="h-future-directions-for-dream-research">Future directions for dream research</h2>



<p>This study offers valuable insights into why some people vividly recall dreams while others wake up with no memory of them. </p>



<p>It confirms that dream memory is influenced by a combination of personal traits, sleep patterns, and external conditions. However, many questions remain unanswered.</p>



<p>Future research could explore whether specific lifestyle changes, such as meditation or sleep training, enhance dream recall. </p>



<p>Additionally, understanding the link between dream memory and mental health may provide new ways to study consciousness and emotional processing during sleep.</p>



<p>Scientists continue to uncover the mysteries of the sleeping mind, but one thing is clear - dreaming is a deeply personal experience shaped by both biology and behavior. The more we learn, the closer we get to understanding the hidden world of our dreams.</p>



<p>The study is published in the journal <em><a href="https://www.nature.com/articles/s44271-025-00191-z" target="_blank" rel="noreferrer noopener">Communications Psychology</a>.</em></p>

Dream recall: Who remembers their dreams and why?

Dreams have fascinated humans for centuries, yet not everyone remembers...

<p>Toxins can give valuable insights into how molecules interact with biological targets, helping scientists design safer and more effective compounds.</p>



<p>Whether for life-saving drugs, species control, or agriculture, understanding a molecule’s precise targets is crucial for ensuring its safe and effective use.</p>



<p>Researchers at the <a href="https://www.weizmann.ac.il/pages/" target="_blank" rel="noreferrer noopener">Weizmann Institute</a> in Israel have developed an innovative AI-powered pipeline to predict how natural toxins interact with proteins. </p>



<p>By combining artificial intelligence with traditional research methods, they are unlocking new possibilities in ecological studies and drug development.</p>



<h2 class="wp-block-heading" id="h-secrets-of-a-deadly-snail-toxin">Secrets of a deadly snail toxin</h2>



<p>The journey of these scientists kicked off from an unlikely source - a toxin from the <a href="https://www.earth.com/news/cone-snail-venom-could-be-used-to-produce-painkillers/" target="_blank" rel="noreferrer noopener">cone snail</a> (<em>Conus striatus</em>) that affects both insects and fish. This protein is composed of 60 amino acids and is shot into the prey by the snail using a sharp barb.</p>



<p>Dr. Izhar Karbat and Dr. Eitan Reuveny set out to investigate how the cone snail toxin Conkunitzin-S1 (Cs1) works to immobilize fish, despite not affecting mammals or <a href="https://www.earth.com/news/mollusks-evolution-shishania-aculeata-spiny-armor-no-shells-500-million-years-ago/" target="_blank" rel="noreferrer noopener">mollusks</a>.</p>



<p>The experts found that Cs1 blocks potassium channels that are central to cell function in fruit flies and other insects. However, the molecular target of this toxin in fish remained a mystery.</p>



<h2 class="wp-block-heading" id="h-turning-to-ai-for-answers">Turning to AI for answers</h2>



<p>Unable to pinpoint the target of the Conkunitzin toxin using traditional methods, the scientists turned to <a href="https://www.earth.com/news/artificial-intelligence-proves-very-useful-to-doctors-when-diagnosing-patients/" target="_blank" rel="noreferrer noopener">artificial intelligence</a>.</p>



<p>“Three years ago, we tried our best tools at the time to find the target of the Conkunitzin toxin, and we failed because the tools were not good enough. And then came a big revolution in structural biology driven by artificial intelligence,” said Karbat.</p>



<p>This presented an invaluable tool for their research, which enabled the experts to use a two-pronged approach to identify the fish potassium channels that were most vulnerable to Cs1.</p>



<p>They harnessed the power of AlphaFold, an AI program, to predict how the toxin might bind to different fish potassium channels. </p>



<p>Next, the researchers developed another AI model, ET3, to analyze how water molecules navigate around these channels.</p>



<h2 class="wp-block-heading" id="h-ai-pinpoints-the-toxin-s-true-targets">AI pinpoints the toxin’s true targets</h2>



<p>By leveraging ET3 to analyze a broad range of fish potassium channels - beyond what was previously possible - the experts identified the exact channels targeted by Cs1 and how the toxin disrupts their function.</p>



<p>Essentially, if potassium channels act as tiny doors regulating ion flow in and out of cells, Cs1 functions like a lock that jams those doors shut.</p>



<p>“Using molecular dynamics and the new AI-driven structural tools, we were able to find the small subset of channels in fish which bind our toxins with high affinity and are probably the real target of the cone snail,” said Dr. Karbat.</p>



<h2 class="wp-block-heading" id="h-identifying-precise-targets-for-new-drugs">Identifying precise targets for new drugs </h2>



<p>Beyond unraveling the mystery of Cs1’s impact on <a href="https://www.earth.com/news/oceans-are-quickly-losing-ability-to-support-fish-due-to-plankton-loss/" target="_blank" rel="noreferrer noopener">fish</a>, the researchers see broader applications for their AI-powered approach. </p>



<p>“This new pipeline offers exciting opportunities and future prospects with ecological studies, to study real chemical interactions in real ecological systems,” said Dr. Karbat.</p>



<p>Additionally, the same methodology could be applied to drug development, helping to identify precise targets for new drugs while avoiding unintended interactions.</p>



<p>“If you develop a drug that would activate a channel in the human brain, you wouldn’t want the same drug to affect a channel in the human heart and cause a heart attack,” noted Dr. Karbat.</p>



<p>“The power of this pipeline is that we can concentrate on a target, or any molecule that we are interested in, and find its match,” added Dr. Reuveny, emphasizing the effectiveness of this approach. .</p>



<h2 class="wp-block-heading" id="h-expanding-ai-s-role-in-molecular-research">Expanding AI’s role in molecular research</h2>



<p>The success of this AI-powered pipeline extends far beyond the study of cone snail toxins. </p>



<p>The ability to predict molecular interactions accurately could transform the way scientists approach drug discovery, environmental toxicology, and even disease treatment.</p>



<p>One of the most promising applications lies in developing highly specific drugs that target only the intended receptors, thus minimizing side effects. By refining molecular targeting, AI can help create treatments that are both safer and more effective.</p>



<p>Additionally, this approach could be used to study natural toxins other than Cs1, such as <a href="https://www.earth.com/news/deadly-snail-venom-possible-key-to-improving-diabetes-medicine/" target="_blank" rel="noreferrer noopener">venom</a> components from other marine creatures, snakes, scorpions or even plants.</p>



<p>Understanding how these compounds interact with biological systems could inspire new medical treatments, from pain relief to antimicrobial drugs.</p>



<p>The research also holds promise for ecological conservation. By mapping how toxins influence different species, scientists can better predict how environmental changes or chemical pollutants may affect ecosystems.</p>



<p>As AI continues to revolutionize molecular biology, tools like AlphaFold and ET3 will likely become standard in many areas of research, bridging the gap between computational predictions and real-world biological interactions.</p>



<p>The work will be presented at the <a href="https://www.biophysics.org/2025meeting/program/">69th Biophysical Society </a>Annual Meeting in Los Angeles.</p>

Cone snail toxin has inspired a breakthrough in drug discovery

Toxins can give valuable insights into how molecules interact with...

<p>Across Kenya, grasslands serve as a crucial lifeline for both local communities and wildlife, from elephants and giraffes to hyenas. However, climate-driven drought is drying out these habitats, forcing animals and people to vie for diminishing resources - and fueling conflict.&nbsp;</p>



<p>Now, new research shows that restoring more grassland significantly reduces clashes and boosts safety for everyone.</p>



<p>“Grassland restoration is playing a role in reducing <a href="https://www.earth.com/news/human-wildlife-overlap-is-rapidly-rising-across-the-globe/" target="_blank" rel="noreferrer noopener">human-wildlife conflicts</a>, social conflicts and the overall feeling of insecurity in Chyulu Hills, Kenya,” said study leader Camila Donatti, a scientist at Conservation International.&nbsp;</p>



<p>“Grasslands maintain 60% of the livestock produced in Kenya and support 70% of all the wildlife that is found outside protected areas, so people, livestock, and wildlife rely on those grasslands for their survival and live in close proximity. This means this system is ideal for studying the connections between grassland restoration and peace and security.”</p>



<h2 class="wp-block-heading" id="h-droughts-escalate-competition-for-resources">Droughts escalate competition for resources</h2>



<p>With the climate crisis intensifying, <a href="https://www.earth.com/news/droughts-and-extreme-weather-events-are-escalating/" target="_blank" rel="noreferrer noopener">droughts</a> have grown more severe, reducing vegetation and leaving less food for both livestock and wildlife.&nbsp;</p>



<p>In Chyulu Hills, researchers surveyed 1,567 households and found that 89% faced some form of conflict with wildlife, while 32% experienced social disputes with other residents. The area is predicted to suffer even more pronounced droughts in the next 30 years, further imperiling resources and livelihoods.</p>



<p>“Grasslands prevent soil erosion while supporting agriculture and livestock grazing, which sustain the livelihoods of pastoralists and farmers in Kenya,” explained Maureen Mwanzia, formerly with Conservation International Kenya and now a statistician at the World Health Organization.&nbsp;</p>



<p>“Additionally, they support rich biodiversity. Beyond their ecological functions, grasslands hold cultural significance and offer tourism and recreation opportunities, making their protection and restoration essential for both environmental and human well-being.”</p>



<h2 class="wp-block-heading" id="h-tracking-conflicts-in-restored-grasslands-nbsp">Tracking conflicts in restored grasslands&nbsp;</h2>



<p>Beginning in October 2021, 11,000 hectares of grassland in the Chyulu Hills were earmarked for rehabilitation. </p>



<p>From September 2022 to October 2023, researchers interviewed local households near these restored sites to understand the scale of human-wildlife interactions, such as crop raids and livestock attacks. The team also wanted to document social tensions, like disagreements over land use.</p>



<p>“Of the total households interviewed, 23% had at least one member experiencing non-lethal attacks by wildlife,” Donatti said. “<a href="https://www.earth.com/news/human-elephant-conflict-will-escalate-with-climate-change/" target="_blank" rel="noreferrer noopener">Elephants</a>, giraffes, lions, spotted hyenas, and buffalos were the most likely species to be involved.”&nbsp;</p>



<p>Conflicts often spiked during the rainy season, when predators sometimes turn to livestock and herbivores stray into ripening fields.</p>



<p>However, the study revealed that households near larger restored grassland areas encountered fewer wildlife conflicts, though overall conflict levels stayed relatively flat across time. Researchers attribute this to the still-limited size of restored grasslands compared with animals’ broad ranges.</p>



<h2 class="wp-block-heading" id="h-restored-grassland-reduces-community-disputes">Restored grassland reduces community disputes</h2>



<p>Besides curbing wildlife clashes, restored grassland appeared to lower social conflicts and a sense of insecurity within local populations. </p>



<p>Over the study period, people’s perceptions of safety generally improved where more habitat restoration was underway - though women-led households reported more social conflict and uncertainty than male-led households.</p>



<p>“However, we only have 16 months of data,” Donatti cautioned. “Tracking conflicts should continue in the area to understand long-term patterns.”&nbsp;</p>



<p>“Additionally, the information we requested from household members relates to the conflicts and mitigation strategies we have previously identified; other conflicts and strategies may have been happening in the area.”</p>



<p>“Finally, household surveys do not properly capture retaliatory measures on wildlife. These should be assessed using a different methodology.”</p>



<h2 class="wp-block-heading" id="h-potential-of-large-scale-grassland-restoration-nbsp">Potential of large-scale grassland restoration&nbsp;</h2>



<p>Based on these findings, Mwanzia underscored the potential for large-scale grassland restoration to foster both ecological and social benefits.</p>



<p>“I would like to see the integration of grassland restoration into national and international environmental and development strategies, with dedicated funding and resources,” said Mwanzia.&nbsp;</p>

Across Kenya, grasslands serve as a crucial lifeline for both...

<p>A newly published study investigates how complex chemical mixtures respond to repeated environmental fluctuations, providing insights into prebiotic processes that may have paved the way for life on Earth.&nbsp;</p>



<p>By exposing various organic molecules to cycles of drying and rehydration, researchers observed continuous transformations, selective organization, and synchronized shifts among molecular populations. These behaviors help clarify how early chemical systems could have achieved the complexity needed for life.</p>



<p>The study, published in <a href="https://dx.doi.org/10.1038/s41557-025-01734-x" target="_blank" rel="noreferrer noopener"><em>Nature Chemistry</em></a>, demonstrates that repeated wet-dry cycles not only altered chemical compositions but also guided these shifts in a structured, rather than random, way.&nbsp;</p>



<p>The findings suggest that changing environmental factors might have played an active role in fostering the molecular diversity that was necessary for life to emerge on Earth.</p>



<h2 class="wp-block-heading" id="h-simulating-early-environmental-cycles">Simulating early environmental cycles</h2>



<p>To explore how <a href="https://www.earth.com/news/clues-to-lifes-beginnings-found-in-ancient-chemical-reactions/" target="_blank" rel="noreferrer noopener">chemical evolution</a> may have played out billions of years ago, scientists subjected mixtures containing diverse functional groups - such as carboxylic acids, amines, thiols, and hydroxyls - to multiple rounds of drying out and rehydration.&nbsp;</p>



<p>In essence, they mimicked the environmental swings thought to be common on the early Earth, including periods of moisture followed by arid conditions.&nbsp;</p>



<p>Rather than producing disorganized reactions, the mixtures organized themselves and evolved along predictable patterns.</p>



<p>This challenges the notion that early chemical pathways were entirely haphazard. Instead, the results imply that nature’s fluctuations - like brief rain showers in ancient shallow ponds or tidal zones - could have steered molecules in specific, constructive directions.&nbsp;</p>



<p>Over long spans of time, these guided transformations may have led to increasingly sophisticated molecular systems akin to the <a href="https://www.earth.com/news/how-did-the-building-blocks-of-life-form/" target="_blank" rel="noreferrer noopener">building blocks of life</a>.</p>



<h2 class="wp-block-heading" id="h-environmental-changes-and-chemical-reactions">Environmental changes and chemical reactions</h2>



<p>The study was conducted by Dr. Moran Frenkel-Pinter from the Institute of Chemistry at the <a href="https://en.huji.ac.il/" target="_blank" rel="noreferrer noopener">Hebrew University of Jerusalem</a> and Professor Loren Williams from the <a href="https://www.gatech.edu/" target="_blank" rel="noreferrer noopener">Georgia Institute of Technology</a>.</p>



<p>The research team shows how chemical systems evolve steadily while preserving structural coherence. Their focus was on continuous transformation: even as molecules changed or formed new bonds, the overall system avoided devolving into chaos.</p>



<p>Chemical evolution generally refers to the gradual complexification of molecules in conditions that predate life. This concept is essential for explaining how biologically relevant compounds, such as amino acids and nucleotides, eventually appeared.&nbsp;</p>



<p>While much prior research zeroed in on individual chemical reactions or specific molecules, this new work sets up a more all-encompassing model of how an entire mixture might behave under environmental changes.&nbsp;</p>



<h2 class="wp-block-heading" id="h-environmental-cycles-and-molecular-variety">Environmental cycles and molecular variety </h2>



<p>In particular, the researchers uncovered three significant observations. First, chemical systems continued to evolve without reaching a stable equilibrium, suggesting that persistent environmental stimuli, like wet-dry cycles, can keep driving new reactions.&nbsp;</p>



<p>Second, although the mixtures contained many types of molecules, they did not expand into an unwieldy soup of complexity. Instead, certain chemical routes were favored, restricting random pathways and maintaining organization.&nbsp;</p>



<p>Finally, different molecular species showed interlinked patterns of emergence and decline, implying that some molecules depended on or facilitated the formation of others in a coordinated way.</p>



<p>Collectively, these aspects highlight how environmental shifts could encourage the development of molecular variety while preserving orderly growth - characteristics essential to the emergence of living systems.</p>



<h2 class="wp-block-heading" id="h-potential-mechanisms-for-the-emergence-of-life">Potential mechanisms for the emergence of life</h2>



<p>By focusing on how entire mixtures adapt and transform over multiple cycles, the study helps bridge the gap between classical prebiotic chemistry (which often probes single reactions) and the broader question of how life got started.</p>



<p>“This research offers a new perspective on how molecular evolution might have unfolded on early Earth,” said Frenkel-Pinter.</p>



<p>“By demonstrating that chemical systems can self-organize and evolve in structured ways, we provide experimental evidence that may help bridge the gap between prebiotic chemistry and the emergence of biological molecules.”</p>



<p>The team envisions that repeated wet-dry cycles in ancient environments - like shallow basins or tidally influenced regions - could have systematically steered chemical mixtures to form increasingly complex networks.&nbsp;</p>



<p>Over time, such processes could cultivate the right conditions for molecules capable of replication and <a href="https://www.earth.com/news/human-metabolism-has-evolved-to-become-energetically-unique/" target="_blank" rel="noreferrer noopener">metabolism</a>, key signatures of life.</p>



<h2 class="wp-block-heading" id="h-early-stages-of-life-on-earth">Early stages of life on Earth</h2>



<p>Though primarily aimed at unraveling life’s early stages, the study’s findings might also be applied in synthetic biology and nanotechnology.&nbsp;</p>



<p>The authors suggest that controlled chemical evolution - exploiting periodic changes in the environment - could lead to new ways of producing molecular systems with desired traits. This might include specialized polymers, novel catalysts, or even biologically inspired <a href="https://www.earth.com/news/nanotech-material-graphene-passes-human-safety-tests/" target="_blank" rel="noreferrer noopener">nanomaterials</a>.</p>



<p>Additionally, a better understanding of how chemical systems self-organize could inform <a href="https://www.earth.com/news/oral-peptides-pave-the-way-for-new-drug-development/" target="_blank" rel="noreferrer noopener">drug development</a>, helping researchers design molecules that adapt to varied conditions within the human body.&nbsp;</p>



<p>The self-organizing principle could also prove beneficial in engineering tasks where complex, adaptive behavior is desired - much like living cells operate via coordinated chemical pathways.</p>



<h2 class="wp-block-heading" id="h-from-simple-molecules-to-complex-life">From simple molecules to complex life</h2>



<p>While this study highlights how fluctuations in ancient Earth’s environment might have propelled chemical complexity, many questions remain about the full path from simple molecules to the first true life forms.&nbsp;</p>



<p>The authors advocate for broader experiments that expand on the current approach: using more varied chemical compositions, testing different pH levels or temperature ranges, and coupling the results with genetic-like feedback mechanisms.</p>



<p>The researchers hope this approach will unravel further details about how molecules collaborate, outcompete, and reshape one another in dynamic chemical “ecosystems.”&nbsp;</p>



<p>Such knowledge is not only essential for understanding how life may have arisen but could also guide how we harness or replicate these evolutionary tricks in modern science and industry.</p>

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air"><strong>Invisible threat in urban air</strong></h2>



<p>City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.</p>



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge"><strong>Disturbing connections emerge</strong></h2>



<p>Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.</p>



<h2 class="wp-block-heading" id="h-timing-matters"><strong>Timing matters</strong></h2>



<p>The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.</p>



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns"><strong>Genetic vulnerability patterns</strong></h2>



<p>Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.</p>



<h2 class="wp-block-heading" id="h-public-health-implications"><strong>Public health implications</strong></h2>



<p>These findings, published in <em><a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a></em>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.</p>



<p>As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.</p>

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



<p>Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.</p>



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



<p>The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.</p>



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



<p>At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.</p>



<p>"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.</p>



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



<p>The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.</p>



<p>The research, published in <em><a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a></em> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.</p>

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



<p>Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.</p>



<h2 class="wp-block-heading" id="h-the-discovery">The discovery</h2>



<p>Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.</p>



<p>Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."</p>



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



<p>The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.</p>



<p>Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.</p>



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



<p>Published in the journal <em><a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a></em>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.</p>

<h2 class="wp-block-heading" id="h-a-contrasting-climate-response">A contrasting climate response</h2>



<p>Most coastal towns are <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">preparing for higher sea levels</a>, but <a href="https://www.earth.com/news/greenland-no-longer-has-to-worry-about-rising-sea-levels/" target="_blank" rel="noreferrer noopener">Greenland presents</a> a different scenario during climate change. The ground there is rising at a remarkable rate. Over the past decade, some areas have lifted about 20 centimeters, which translates to roughly 2 meters per century. This rate significantly exceeds current projections for sea level rise.</p>



<h2 class="wp-block-heading" id="h-geological-rebound-process-through-climate-change">Geological rebound process through climate change</h2>



<p>The mechanism behind this phenomenon is straightforward. As the ice sheet melts, the immense weight is removed from the bedrock, causing the land to rebound upward. This process resembles the way compressed material springs back when pressure is released.</p>



<h2 class="wp-block-heading" id="h-scientific-monitoring-networks">Scientific monitoring networks</h2>



<p>Researchers at the <a href="https://www.dtu.dk/english/" target="_blank" rel="noreferrer noopener">Technical University of Denmark</a> are documenting this uplift using the GNET network, consisting of 61 GPS stations positioned around Greenland's coast. These sensors can detect movement with millimeter precision, providing detailed measurements of the ongoing changes.</p>



<p>The data reveal that current uplift rates exceed the gradual rebound occurring since the last ice age ended approximately 12,000 years ago. This acceleration corresponds directly with increased ice sheet melting rates.</p>



<h2 class="wp-block-heading" id="h-coastal-transformation">Coastal Transformation</h2>



<p>This uplift is actively reshaping Greenland's coastline. New islands and rocky formations, called "skerries," are emerging as previously submerged land surfaces rise above the water level. This represents a notable contrast to global concerns about rising seas.</p>



<p>The study, published in Geophysical Research Letters, demonstrates the varied regional impacts of climate change. While many locations face rising water levels, Greenland's bedrock is literally rising above the surrounding seas.</p>



<p>The full study was recently published in <em><a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL104851" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a></em>.</p>

<h2 class="wp-block-heading" id="h-ai-agent-training-transforms-the-workplace-fear-factor-into-a-competitive-advantage">AI agent training transforms the workplace 'fear factor' into a competitive advantage</h2>



<p>Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.</p>



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



<p>A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.</p>



<p>Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.</p>



<p>Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents".  In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively.   MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.</p>



<p>MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization.  The training provided by MindStudio is applicable across other AI Agent building platforms as well.</p>



<h2 class="wp-block-heading" id="h-revolutionary-productivity-through-focused-learning">Revolutionary productivity through focused learning</h2>



<p>Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.</p>



<p>Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.</p>



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



<p>The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.</p>



<p>A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.</p>



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



<p>Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.</p>



<p>This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.</p>



<h2 class="wp-block-heading" id="h-financial-benefits-of-increased-retention">Financial benefits of increased retention</h2>



<p>The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.</p>



<p>PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.</p>



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



<p>AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.</p>



<p>In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.</p>



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



<p>The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.</p>



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



<p>Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.</p>



<p>The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.</p>



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



<p>The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.</p>



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



<p>While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.</p>



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



<p>As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.</p>



<p>The study is published in the journal&nbsp;<a href="http://dx.doi.org/10.1038/s41467-023-44335-3" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a>.</p>

<h2 class="wp-block-heading" id="h-other-people-s-reactions-influence-children-s-eating-habits">Other people's reactions influence children's eating habits</h2>



<p>Many children are finicky eaters, but research explains how <a href="https://www.earth.com/news/scientists-have-learned-why-so-many-kids-dislike-vegetables/" target="_blank" rel="noreferrer noopener">watching others eat and social modeling</a> influence the eating habits of children.</p>



<h2 class="wp-block-heading">Study Methodology Demonstrates Social Learning Impact</h2>



<p>Researchers at <a href="https://www.aston.ac.uk/hls/school-of-psychology" target="_blank" rel="noreferrer noopener">Aston University School of Psychology</a> have published findings in Frontiers in Psychology that illuminate the neurobiological foundations of food preference development through observational learning. The investigation employed controlled video stimuli featuring adults consuming raw broccoli while displaying systematically varied facial expressions to measure participant responses.</p>



<h2 class="wp-block-heading">Asymmetrical Response Patterns Identified</h2>



<p>The research, conducted with 204 female participants, revealed a pronounced asymmetry in social modeling effects. Negative facial expressions during vegetable consumption significantly diminished observer food preference ratings, while positive expressions failed to produce corresponding increases in vegetable appeal. This finding challenges conventional assumptions about the bidirectional nature of social influence in dietary behavior formation.</p>



<h2 class="wp-block-heading">Evolutionary Psychology Framework Applied</h2>



<p>Dr. Katie Edwards and her research team propose that these results reflect adaptive mechanisms developed through evolutionary processes. The heightened sensitivity to disgust expressions likely functions as a protective system, enabling individuals to identify potentially harmful foods through social cues without direct risk exposure.</p>



<h2 class="wp-block-heading">Clinical and Educational Implications</h2>



<p>These findings carry substantial implications for pediatric nutrition interventions and family meal dynamics. The research suggests that parental expressions of distaste during vegetable consumption may inadvertently reinforce children's existing food aversions through unconscious social transmission pathways.</p>



<h2 class="wp-block-heading">Future Research Directions</h2>



<p>The study establishes a foundation for expanded investigation into real-time social modeling effects and cross-demographic applicability. Researchers emphasize the necessity for longitudinal studies examining actual consumption behaviors rather than preference ratings alone, particularly within family contexts where social learning occurs most frequently.</p>

<h2 class="wp-block-heading" id="h-cancer-causing-protein-bound-and-blocked">Cancer-causing protein bound and blocked</h2>



<p>In a discovery that can one day revolutionize cancer treatment, researchers at the <a href="https://www.ucr.edu/" target="_blank" rel="noreferrer noopener">University of California, Riverside</a> have successfully developed a means of controlling MYC, a notoriously slippery protein that causes approximately <a href="https://www.earth.com/news/chaotic-protein-that-fuels-75-of-cancers-can-be-controlled/" target="_blank" rel="noreferrer noopener">75% of all cancers in humans</a>.</p>



<h2 class="wp-block-heading" id="h-what-makes-myc-different">What makes MYC different</h2>



<p>MYC presents a unique challenge when studying cancer. Normally, this protein plays a vital role in healthy cells. It carefully controls transcription - the process that converts genetic information from DNA and RNA into proteins.</p>



<p>However, cancer changes everything. In cancer cells, MYC becomes a destructive force. It operates in overdrive mode with no regulation whatsoever.</p>



<p>Professor Min Xue, who led the research team, explains it simply: "MYC is less like food for cancer cells and more like a steroid. It drives cancer's aggressive growth." This superactive behavior makes MYC involved in three out of every four cancer cases.</p>



<h2 class="wp-block-heading" id="h-why-myc-is-hard-to-target">Why MYC is hard to target</h2>



<p>Despite its clear role in cancer, targeting MYC has been one of medicine's biggest challenges. The main problem lies in MYC's unusual structure - or rather, its complete lack of structure.</p>



<p>Professor Xue describes the protein as "basically a glob of randomness." This means conventional drug discovery methods don't work. These traditional approaches rely on sharply defined protein structures. MYC simply doesn't have one.</p>



<h2 class="wp-block-heading">A New Approach to Fighting MYC</h2>



<p>The UCR research team developed a clever solution. They designed a special peptide molecule that could selectively bind to MYC. More importantly, this peptide could block MYC's destructive activity.</p>



<p>The key was fine-tuning two specific features: the peptide's stiffness and its shape. Through careful adjustments, researchers achieved something remarkable. They reached "sub-micro-molar affinity" - meaning their peptide binds as strongly as antibodies do.</p>



<h2 class="wp-block-heading" id="h-breakthrough-results">Breakthrough results</h2>



<p>This accomplishment represents a major leap beyond previous attempts. The researchers enhanced their peptide's binding strength by two orders of magnitude. This dramatic improvement brings the work significantly closer to practical drug development goals.</p>



<p>The research opens new possibilities for treating the vast majority of cancers where MYC plays a destructive role.</p>



<p>The researchers are presently optimizing peptide-delivery systems based on lipid nanoparticles that deliver the peptide effectively into cancer cells. The<a href="https://www.nih.gov/" target="_blank" rel="noreferrer noopener"> National Institutes of Health</a> and the <a href="https://www.defense.gov/" target="_blank" rel="noreferrer noopener">U.S. Department of Defense</a> funded the study, which appeared in the Journal of the <a href="https://www.acs.org/" target="_blank" rel="noreferrer noopener">American Chemical Society</a>.<br>This research offers renewed hope against cancer, and it can potentially open a door to more effective cancer therapies for most cancer patients worldwide.</p>

<p>On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.</p>



<p>This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.</p>



<p>Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.</p>



<p>The find upsets the traditional timeline of sea predators.  Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas.  These worms were building sophisticated food webs several million years before other predator groups arose.</p>



<p>Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.</p>

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



<p>Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.</p>



<p>Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.</p>



<h2 class="wp-block-heading" id="h-the-cairo-forest-discovery">The Cairo forest discovery</h2>



<p>385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.</p>



<p>The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.</p>



<p>Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.</p>



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



<p>The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."</p>



<p>This discovery pushes back advanced tree evolution by millions of years. The research, published in <em><a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a></em> in December 2019, fundamentally changes our understanding of when complex forests first emerged.</p>



<p>Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.</p>



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet <em>Archaeopteris</em>: the first modern tree</h2>



<p>The star of this ancient forest is <em>Archaeopteris</em> – not to be confused with the feathered dinosaur <em>Archaeopteryx</em>. This tree was far older and more revolutionary.</p>



<p>William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.</p>



<p>Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.</p>



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



<p>These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.</p>



<p>This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.</p>



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



<p>The forest was remarkably diverse. Scientists identified <em>Eospermatopteris</em>, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.</p>



<p>All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.</p>



<h2 class="wp-block-heading" id="h-scientific-significance">Scientific significance</h2>



<p>Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.</p>



<p>Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."</p>



<p>The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.</p>



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



<p>In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.</p>



<p>Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.</p>



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



<p>Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.</p>



<p>Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.</p>



<p>These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.</p>



<p>The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.</p>



<p>The full study was published in the journal <em>Current Biology</em>.</p>

</div><figcaption class="wp-element-caption">Our bodies hits two 'aging cliffs' at these ages.</figcaption></figure>



<h2 class="wp-block-heading" id="h-scientists-map-exact-ages-when-your-body-rapidly-ages">Scientists Map Exact Ages When Your Body Rapidly Ages</h2>



<p>Scientists have <a href="https://www.earth.com/news/human-bodies-begin-breaking-down-two-very-precise-ages/#google_vignette">discovered that aging</a> isn't the gradual, steady process many assume it to be. Instead, researchers from Stanford Medicine have found that our bodies undergo dramatic molecular changes at two specific ages: 44 and 60. This research, published in Nature Aging, reveals that aging happens in sudden bursts rather than smooth transitions.</p>



<h2 class="wp-block-heading" id="h-two-waves-of-rapid-aging">Two waves of rapid aging</h2>



<p>The Stanford study tracked over 135,000 different molecules and microbes in 108 participants aged 25 to 75 over several years. Results showed that 81% of all molecules studied exhibited non-linear changes, meaning they shifted dramatically at certain ages rather than changing gradually over time.</p>



<p>Michael Snyder, chair of genetics at Stanford School of Medicine and the study's senior author, noted significant findings. "We're not just changing gradually over time; there are some really dramatic changes. It turns out the mid-40s is a time of dramatic change, as is the early 60s. And that's true no matter what class of molecules you look at."</p>



<p>The first wave of changes occurs around age 44, affecting molecules related to alcohol metabolism, caffeine processing, lipid <a href="https://www.earth.com/news/age-related-changes-in-metabolism-dont-match-our-expectations/" target="_blank" rel="noreferrer noopener">metabolism</a>, <a href="https://www.earth.com/news/heart-disease-remains-the-leading-cause-of-death-worldwide/" target="_blank" rel="noreferrer noopener">cardiovascular disease</a>, and skin and muscle function. The second wave hits around age 60, involving changes in carbohydrate metabolism, immune regulation, kidney function, and again cardiovascular and muscle health.</p>



<h2 class="wp-block-heading" id="h-what-happens-during-these-aging-bursts">What happens during these aging bursts</h2>



<p>During the mid-40s transformation, researchers observed significant changes in how the body processes alcohol and fats. This period often coincides with increased stress levels in many people's lives, potentially contributing to lifestyle factors that accelerate these molecular shifts.</p>



<p>"It's possible some of these changes could be tied to lifestyle or behavioral factors that cluster at these age groups, rather than being driven by biological factors," Snyder explained. For instance, alcohol metabolism dysfunction might result from increased consumption during the typically stressful mid-40s period.</p>



<p>The changes at age 60 are perhaps less surprising, as this is when many age-related diseases begin to manifest more prominently. The molecular shifts affect immune function and kidney health, both critical for maintaining overall wellness as we enter our senior years.</p>



<h2 class="wp-block-heading" id="h-latest-research-confirms-aging-patterns">Latest research confirms aging patterns</h2>



<p>Recent 2025 studies have validated these findings. Research examining tissue samples from 76 people found similar aging patterns, noting an "inflection point" between ages 45 and 55.</p>



<p>Scientists discovered that blood vessels, particularly the aorta, age fastest among all body tissues. This vascular aging may drive aging in other body parts, highlighting cardiovascular health's central role in the aging process.</p>



<h2 class="wp-block-heading" id="h-cellular-changes-and-microbiome-shifts">Cellular changes and microbiome shifts</h2>



<p>The Stanford research revealed that these aging bursts affect our microbiome – the trillions of bacteria, viruses, and fungi living in and on our bodies. These microbial communities undergo substantial shifts during both aging periods, potentially affecting everything from digestion to immune function.</p>



<p>Additionally, researchers found that protein production and gene expression begin to fall out of sync as we age. This breakdown in cellular communication becomes especially pronounced during the two aging waves, contributing to the accumulation of damaged proteins associated with diseases such as <a href="https://www.earth.com/news/alzheimers-may-not-be-brain-disorder-important-data-was-fabricated/" target="_blank" rel="noreferrer noopener">Alzheimer's</a>.</p>



<h2 class="wp-block-heading" id="h-health-implications-and-longevity-considerations">Health implications and longevity considerations</h2>



<p>Understanding these aging patterns has important implications for healthcare strategies. Research suggests that people should pay particular attention to their health during their 40s and 60s, when these dramatic molecular changes occur.</p>



<p>Snyder emphasized the importance of proactive health measures. "I'm a big believer that we should try to adjust our lifestyles while we're still healthy," he noted. This might include increasing exercise to protect heart health and maintain muscle mass, or reducing alcohol consumption in the 40s as the body's ability to metabolize it declines.</p>



<h2 class="wp-block-heading" id="h-new-approaches-to-anti-aging-treatment">New approaches to anti-aging treatment</h2>



<p>Aging research has seen notable advances in 2025. Harvard Medical School scientists developed chemical cocktails that reverse cellular aging without genetic modification. These six combinations restored aged cells to youthfulness in under a week, offering safer alternatives to gene therapy.</p>



<p>Researchers identified new biomarkers like "InflammAge," a saliva-based test measuring chronic inflammation associated with aging. This non-invasive approach could change how we monitor aging and intervention.</p>



<h2 class="wp-block-heading" id="h-future-directions-in-aging-research">Future directions in aging research</h2>



<p>Emerging technologies including artificial intelligence, cellular reprogramming, and senolytic therapies, are opening new possibilities for extending healthspan. Companies develop treatments targeting aging's fundamental mechanisms rather than just managing age-related diseases.</p>



<p>The Stanford findings provide a roadmap for implementing preventive measures. Rather than waiting for symptoms, people can prepare for and potentially mitigate these predictable aging waves.</p>



<p>As aging understanding evolves, one thing becomes clear: aging isn't inevitable decline, but specific biological events we may learn to prevent or reverse. The key is recognizing when these transitions occur and taking proactive health steps during vulnerable periods.</p>

<h2 class="wp-block-heading" id="h-scientists-discover-the-brain-s-tickling-command-center">Scientists discover the brain's 'tickling command center'</h2>



<p>Researchers have finally solved one of humanity's most enduring mysteries: why we can't <a href="https://www.earth.com/news/after-centuries-of-debate-we-still-dont-know-how-tickling-works/" target="_blank" rel="noreferrer noopener">tickle</a> ourselves and what makes some people incredibly ticklish while others barely react? Recent scientific discoveries are revolutionizing our understanding of this peculiar human behavior.</p>



<h2 class="wp-block-heading" id="h-breakthrough-discovery-in-the-brain">Breakthrough discovery in the brain</h2>



<p>In 2023, Dr. Michael Brecht's team at <a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Humboldt University</a>-<a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Berlin</a> made a major discovery published in the <a href="https://www.cell.com/iscience/fulltext/S2589-0042(22)01991-5" target="_blank" rel="noreferrer noopener">journal <em>Neuron</em></a>. They identified the brain's actual "tickling command center" – specific neurons in a region called the periaqueductal gray that control both tickling responses and play behavior.</p>



<p>When researchers used cutting-edge optogenetic technology to shut down these neurons in laboratory rats, something remarkable happened. The animals completely lost their ability to be tickled or engage in playful behavior.</p>



<p>"We found that global blockade of the rat periaqueductal gray with either muscimol or lidocaine interfered with ticklishness and play," the research team reported in their study.</p>



<h2 class="wp-block-heading" id="h-two-types-of-tickling-revealed">Two types of tickling revealed</h2>



<p>What we call "tickling" is two completely different phenomena, according to the latest research. Light tickling – that feathery sensation that makes you want to scratch – is essentially your body's sophisticated bug detection system. This alerts you to potential insects or parasites on your skin.</p>



<p>Deep tickling – the kind that makes you laugh uncontrollably – involves complex brain circuits and is fundamentally social. You literally cannot tickle yourself with this type of stimulation.</p>



<h2 class="wp-block-heading" id="h-why-self-tickling-is-impossible">Why self-tickling is impossible</h2>



<p>Your cerebellum acts like a prediction machine, recent findings show. When you move your own hand to touch yourself, your brain generates precise predictions about what you will feel and then cancels out the tickling sensation through neural inhibition.</p>



<p>When someone else tickles you, your brain can't predict their movements, so the full tickling response activates. It's like your brain's way of distinguishing between self and others.</p>



<h2 class="wp-block-heading" id="h-individual-differences-explained">Individual differences explained</h2>



<p>Individual differences in ticklishness depend on genetics, psychology, and even trust. Dr. Xinzhong Dong at <a href="https://www.jhu.edu/" target="_blank" rel="noreferrer noopener">Johns Hopkins University</a> notes that people with denser nerve endings tend to be more sensitive.</p>



<p>Psychological factors matter just as much. You respond more strongly when tickled by people you trust, and anxiety completely shuts down tickling responses. This explains why the same physical stimulus can produce completely different reactions depending on who's doing the tickling.</p>



<h2 class="wp-block-heading" id="h-controlling-your-ticklishness">Controlling your ticklishness</h2>



<p>Science offers answers for controlling your ticklishness. You can reduce tickling sensitivity through systematic desensitization – gradual exposure in controlled settings.</p>



<p>Dr. Konstantina Kilteni's 2025 research, published in <em><a href="https://www.science.org/doi/10.1126/sciadv.adt0350" target="_blank" rel="noreferrer noopener">Science Advances</a></em>, reveals another technique: place your hand on the tickler's hand. This allows your brain to partially predict the sensations, reducing the tickling response by up to 90 percent.</p>



<p>"Your brain is essentially learning to override its own reflexes," Kilteni explained in her review of tickling research.</p>



<h2 class="wp-block-heading" id="h-evolutionary-purpose-discovered">Evolutionary purpose discovered</h2>



<p>From an evolutionary perspective, tickling serves vital functions according to <a href="https://www.umd.edu" target="_blank" rel="noreferrer noopener">University of Maryland</a> researcher Dr. Robert Provine's extensive studies. It trains our defense reflexes for vulnerable body areas and facilitates social bonding between family members.</p>



<p>Tickling-induced laughter is actually one of the first forms of communication between infants and caregivers. "Tickle involves a neurological self/nonself discrimination, providing the most primitive social scenario," Provine noted in his research.</p>



<h2 class="wp-block-heading" id="h-clinical-applications-emerge">Clinical applications emerge</h2>



<p>Research shows people with autism spectrum disorder perceive touches as more ticklish than people without the condition. Investigating this difference could provide insight into brain differences and help advance autism research.</p>



<p>People with schizophrenia tend to experience self-touches similarly to external tickles, allowing them to essentially tickle themselves. This suggests altered sensory prediction mechanisms in the condition.</p>



<h2 class="wp-block-heading" id="h-animal-research-reveals-universal-nature">Animal research reveals universal nature</h2>



<p>Scientists have discovered that many species beyond humans are ticklish. Rats emit ultrasonic "laughs" when tickled, while chimpanzees, gorillas, and orangutans all respond to tickling stimulation.</p>



<p>This widespread occurrence across species suggests that tickling serves fundamental biological and social functions that evolved long before humans developed complex language and culture.</p>



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



<p>Dr. Kilteni argues that tickling research deserves more scientific attention. "It is a complex interplay of motor, social, neurological, developmental, and evolutionary aspects," she stated in her recent review.</p>



<p>New haptic technologies and advanced research methodologies now permit scientists to investigate tickle sensation with unprecedented precision. Standardized experimental methods using mechanical tickling devices ensure consistent results across studies.</p>



<p>Recent findings published in <em>Science Advances</em> show that tickling research is opening new doors in neuroscience, potentially leading to a better understanding of social behavior, sensory processing, and neurological conditions.</p>

</div><figcaption class="wp-element-caption">Dr. Ronald Mallett from the University of Connecticut reveals secret mission to create working time travel device.</figcaption></figure>



<h2 class="wp-block-heading" id="h-could-an-equation-truly-bend-time-a-physicist-s-decades-long-quest-to-rewrite-reality">Could an equation truly bend time? A physicist's decades-long quest to rewrite reality</h2>



<p>Imagine the impossible: stepping back through time in a time machine, not in fantasy, but through a scientific endeavor driven by profound personal loss. For <a href="https://www.earth.com/news/astrophysicist-says-hes-cracked-the-equation-for-time-travel/" target="_blank" rel="noreferrer noopener">Dr. Ronald Mallett</a>, a distinguished astrophysicist and professor emeritus at the <a href="https://uconn.edu/">University of Connecticut</a>, this deeply human longing has fueled a lifelong mission. He claims to have discovered the equation that could unlock temporal displacement, pushing boundaries once deemed purely science fiction.</p>



<h2 class="wp-block-heading" id="h-a-profound-grief-that-forged-a-vision">A profound grief that forged a vision</h2>



<p>Mallett's extraordinary pursuit began with devastating tragedy in 1955. At merely 10 years old, he endured his father Boyd's sudden death—a television repairman whose passion for science had ignited a similar spark in his young son. Boyd Mallett, only 33, succumbed to a heart attack, leaving behind a grief-stricken child searching for solace.</p>



<p>That solace came through H.G. Wells' <em>The Time Machine</em>. Within its pages, Mallett found a captivating concept: "Time is only a kind of Space." These words transformed from a literary phrase into a guiding principle, becoming the driving force behind his unwavering commitment to unraveling time's fundamental mysteries.</p>



<h2 class="wp-block-heading" id="h-from-humble-beginnings-to-academic-heights">From humble beginnings to academic heights</h2>



<p>Mallett's journey was far from straightforward. After serving in the Air Force during the Vietnam War era, he utilized the GI Bill for higher education, earning his Ph.D. in physics from Pennsylvania State University in 1973 at the age of 28.</p>



<p>In 1975, he made history as the first African American professor in the University of Connecticut's physics department, achieving full professorship in 1987 before retiring in 2024 as professor emeritus.</p>



<p>Throughout these successful academic years, Mallett harbored his radical ambition as a closely guarded secret. "I kept my time travel goal a secret," he confessed. "I worried people would think I was nuts." His public research centered on black holes, serving as a "cover story" while he quietly developed his revolutionary time travel theory.</p>



<h2 class="wp-block-heading" id="h-the-breakthrough-moment">The breakthrough moment</h2>



<p>His pivotal insight arrived while hospitalized for a heart condition—a profound irony given his father's heart attack started this journey. The breakthrough was elegantly simple yet revolutionary: "If gravity can bend time, and light can create gravity, then light can bend time."</p>



<p>"It turns out that black holes can create a gravitational field that could lead to the creation of time loops that could allow us to go back in time," he explained.</p>



<h2 class="wp-block-heading" id="h-the-blueprint-for-a-temporal-vortex">The blueprint for a temporal vortex</h2>



<p>Mallett's vision for a functioning time machine replicates spacetime-warping phenomena around black holes. He offers a compelling analogy: "Picture a cup of coffee. Stir it with a spoon, and the coffee swirls. A spinning black hole does the same to spacetime."</p>



<p>In Einstein's general relativity, the universe is a dynamic fabric woven from space and time. Massive objects like black holes warp this fabric—an effect we perceive as gravity. Mallett theorizes that an intense, continuous, circulating beam of light from a ring of powerful lasers could replicate this gravitational torsion, effectively twisting time into a loop.</p>



<p>This "time loop" would theoretically allow information—or perhaps matter—to travel backward in time. He detailed this mathematical concept in his 2006 autobiography, <em>Time Traveler: A Scientist's Personal Mission to Make Time Travel a Reality</em>.</p>



<h2 class="wp-block-heading" id="h-published-research-and-recognition">Published research and recognition</h2>



<p>His work, published in respected journals including <em><a href="https://www.sciencedirect.com/journal/physics-letters-a" target="_blank" rel="noreferrer noopener">Physics Letters A</a></em> and <em><a href="https://link.springer.com/journal/10701" target="_blank" rel="noreferrer noopener">Foundations of Physics</a></em>, suggests circulating laser light could generate gravitational fields potent enough to create closed timelike curves, enabling time travel for data.</p>



<p>Mallett's research has gained worldwide media attention, featured on <a href="https://www.thisamericanlife.org/" target="_blank" rel="noreferrer noopener">National Public Radio's <em>This American Life</em></a>, the <a href="https://www.history.com/" target="_blank" rel="noreferrer noopener">History Channel</a>, and <a href="https://www.today.com/" target="_blank" rel="noreferrer noopener">NBC's <em>Today Show</em></a>. The widespread interest reflects both his compelling personal story and rigorous scientific approach.</p>



<h2 class="wp-block-heading" id="h-the-galactic-hurdles-and-persistent-skepticism">The galactic hurdles and persistent skepticism</h2>



<p>While Mallett's equations captivate imagination, the path to reality faces immense obstacles. The energy requirement is staggering—Mallett acknowledges needing "galactic amounts of energy," far beyond current technological capabilities.</p>



<p>There's also a poignant limitation: even if realized, his machine could only send information back to when it was first activated, meaning it couldn't transport him to 1955 to prevent his father's death.</p>



<p>The scientific community remains skeptical. Physicists Ken Olum and Allen Everett argue that Mallett's proposed laser ring would need to be larger than the observable universe to achieve the necessary spacetime distortion. They invoke Stephen Hawking's chronology protection conjecture, suggesting physics may prevent macroscopic time travel.</p>



<p>Astrophysicist Paul Sutter has voiced doubts about Mallett's underlying mathematics, while science writer Brian Clegg finds the concept intriguing enough to warrant experimental investigation.</p>



<h2 class="wp-block-heading" id="h-a-legacy-that-transcends-time">A legacy that transcends time</h2>



<p>Now approaching 80, Dr. Mallett remains steadfast. "I believe my work will show time travel is possible," he asserts. "Future generations will build on it in ways we can't yet imagine."</p>



<p>His equations, though yet to physically bend time, have bent our collective imagination. Ongoing public interest, evidenced by his continued media appearances and Spike Lee's film adaptation of his memoir, underscores his ideas' profound impact.</p>



<p>More than a scientific pursuit, Mallett's story testifies to human resilience, intellectual courage, and hope's enduring power. Whether his theoretical time machine ever materializes, his legacy is immeasurable—inspiring countless individuals to challenge conventional limits and perceive time not as an unyielding barrier, but as a boundless frontier awaiting exploration.</p>

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



<p>Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?</p>



<p>The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.</p>



<h2 class="wp-block-heading"><strong>What was acid rain?</strong></h2>



<p>Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.</p>



<h2 class="wp-block-heading"><strong>The science behind it</strong></h2>



<p>Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.</p>



<p>While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.</p>



<h2 class="wp-block-heading"><strong>The crisis at its peak</strong></h2>



<p>During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.</p>



<h2 class="wp-block-heading"><strong>Environmental devastation</strong></h2>



<p>The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.</p>



<p>By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.</p>



<p>Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.</p>



<h2 class="wp-block-heading"><strong>Economic impact</strong></h2>



<p>Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.</p>



<h2 class="wp-block-heading"><strong>The solution: government action and technology</strong></h2>



<p>Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.</p>



<h2 class="wp-block-heading"><strong>The Clean Air Act of 1990</strong></h2>



<p>The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.</p>



<h2 class="wp-block-heading"><strong>Cap-and-trade success</strong></h2>



<p>Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.</p>



<p>The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.</p>



<h2 class="wp-block-heading"><strong>Technology advances</strong></h2>



<p>Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.</p>



<p>The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.</p>



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today"><strong>Why we don't hear about it today</strong></h2>



<p>Why did acid rain disappear from headlines? Simple: the problem was largely solved.</p>



<h2 class="wp-block-heading"><strong>Success doesn't make news</strong></h2>



<p>There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.</p>



<h2 class="wp-block-heading"><strong>Mission accomplished</strong></h2>



<p>The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.</p>



<h2 class="wp-block-heading" id="h-is-it-really-gone"><strong>Is it really gone?</strong></h2>



<p>The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.</p>



<p>EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.</p>



<h2 class="wp-block-heading"><strong>What this teaches us</strong></h2>



<p>The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.</p>



<p>Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.</p>



<h2 class="wp-block-heading"><strong>Conclusion</strong></h2>



<p>Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.</p>



<p>Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.</p>



<p>This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.</p>



<p>Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.</p>

<h2 class="wp-block-heading"><strong>Frequently Asked Questions</strong></h2>



<p><strong>1. Is acid rain completely gone?</strong> No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.</p>



<p><strong>2. How long did solving take?</strong> Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.</p>



<p><strong>3. What made the solution successful?</strong> Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.</p>



<p><strong>4. Do other countries have acid rain problems?</strong> Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.</p>



<p><strong>5. Could acid rain return?</strong> Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.</p>



<p><strong>6. Can you recommend any teaching tools on the subject of "acid rain"?</strong> The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a></p>

<p>Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. </p>



<p>The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.</p>



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

<p>Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. </p>



<p>Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.</p>



<p>Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. </p>



<p>They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).</p>



<p>Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.</p>



<p>Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.</p>



<p>This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.</p>



<p>The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.</p>



<p>"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.</p>



<p>"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.</p>



<p>"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.</p>



<p>To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;</p>



<p>"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.</p>



<p>"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."</p>



<p>"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;</p>



<p>The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;</p>



<p>Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.</p>



<p>In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;</p>



<p>According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;</p>



<p>Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. </p>



<p>Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.</p>



<p>Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians. </p>
