<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>



<p>The study is published in the journal <a href="https://resjournals.onlinelibrary.wiley.com/doi/10.1111/icad.70017" target="_blank" rel="noreferrer noopener"><em>Insect Conservation and Diversity</em></a><em>.</em></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.

<p>The <a href="https://wmo.int/" target="_blank" rel="noreferrer noopener">World Meteorological Organization</a> (WMO) is issuing a dire warning about the accelerated pace of <a href="https://www.earth.com/news/global-warming-is-the-strongest-in-7000-years/">global warming</a>, indicating that recent record-breaking environmental changes pose a severe threat to the planet's climate stability. </p>



<p>The Geneva-based agency's latest "State of the Global Climate" report underscores the failure of global efforts to curtail these <a href="https://www.earth.com/news/januarys-record-heat-marks-an-alarming-milestone/">alarming trends</a> and raises concerns about reaching the critical climate threshold outlined in the Paris agreement.</p>



<h2 class="wp-block-heading" id="h-sounding-the-red-alert">Sounding the red alert</h2>



<p>"Never have we been so close – albeit on a temporary basis at the moment – to the 1.5° C lower limit of the Paris agreement on climate change. The WMO community is sounding the red alert to the world," said WMO's secretary-general Celeste Saulo.</p>



<p>Data from the European Union’s <a href="https://climate.copernicus.eu/" target="_blank" rel="noreferrer noopener">Copernicus Climate Change Service</a> (C3S) revealed that the period from March 2023 to February 2024 surpassed the 1.5-degree Celsius increase over pre-industrial levels, averaging 1.56 C (2.81 F) higher. Although the year 2023 remained slightly below this threshold at 1.48 C (2.66 F), a record hot start to 2024 pushed the 12-month average beyond the limit.</p>



<h2 class="wp-block-heading" id="h-a-distress-call-from-the-earth">A distress call from the Earth</h2>



<p>“Earth’s issuing a distress call. The latest State of the Global Climate report shows a planet on the brink. Fossil fuel pollution is sending climate chaos off the charts,” said U.N. Secretary-General Antonio Guterres.</p>



<p>“So we cannot say definitively about 2024 is going to be the warmest year. But what I would say: There is a high probability that 2024 will again break the record of 2023, but let’s wait and see. January was the warmest January on record. So the records are still being broken,” added WMO’s chief of climate monitoring, Omar Baddour.</p>



<h2 class="wp-block-heading" id="h-alarming-environmental-records">Alarming environmental records</h2>



<p>The report presents numerous alarming environmental <a href="https://www.earth.com/news/record-heat-of-2023-likely-exceeds-that-of-the-last-100000-years/">records</a> set in 2023, including unprecedented ocean heat wave conditions affecting over 90% of the world's oceans, historic <a href="https://www.earth.com/news/alarming-study-previously-stable-glaciers-are-now-rapidly-disappearing/">glacier ice loss</a>, and the lowest ever recorded levels of Antarctic sea ice.</p>



<p>“Topping all the bad news, what worries me the most is that the planet is now in a meltdown phase - literally and figuratively given the warming and mass loss from our polar ice sheets,” warned Jonathan Overpeck, dean of the <a href="https://umich.edu/" target="_blank" rel="noreferrer noopener">University of Michigan</a> School for Environment and Sustainability.</p>



<h2 class="wp-block-heading" id="h-tumbling-climate-records">Tumbling climate records</h2>



<p>“2023 was an exceptional year with climate records tumbling like dominoes. Temperatures during 2023 likely exceed those of any period in at least the last 100,000 years,” said Samantha Burgess, deputy director of the Copernicus Climate Change Service.</p>



<p>Managed by the European Commission, C3S compiles temperature readings from multiple sources, including weather stations, balloons, and satellites, to provide a comprehensive view of global air temperature.</p>



<p>“The extremes we have observed over the last few months provide a dramatic testimony of how far we are now from the climate in which our civilization developed,” said Carlo Buontempo, director of C3S, emphasizing the profound implications for the Paris Agreement and all human endeavors.</p>



<h2 class="wp-block-heading" id="h-urgent-climate-warning-nbsp">Urgent climate warning&nbsp;</h2>



<p>The <a href="https://www.earth.com/news/climate-crisis-global-supply-chains-face-25-trillion-in-losses/">climate crisis</a>, according to Saulo, is a critical challenge that humanity must address, compounded by a growing crisis of inequality that manifests in food insecurity and migration patterns.</p>



<p>Despite the overwhelming evidence of climate change's impact, the report offers a sliver of hope with the significant increase in renewable energy capacity, highlighting the critical need for accelerated action to mitigate greenhouse gas emissions.</p>



<h2 class="wp-block-heading" id="h-climate-action-is-needed">Climate action is needed</h2>



<p>The red alert warning has been released just ahead of a significant climate action meeting in Copenhagen on March 21-22. Experts and officials will discuss enhancing national commitments to combat global warming. </p>



<p>The consensus among scientists and experts is clear: urgent and decisive action is necessary to prevent further catastrophic climate change and preserve the planet for future generations.</p>

"Red alert" climate warning issued after 2023 smashed all records

The World Meteorological Organization (WMO) is issuing a dire warning...

<p>Leveraging the whimsical drinking bird toy as their muse, scientists from Hong Kong and Guangzhou, China, have ingeniously engineered a generator that taps into the power of water evaporation to produce electricity. </p>



<p>Consequently, this innovative approach to <a href="https://www.earth.com/news/kite-power-renewable-energy/" target="_blank" rel="noreferrer noopener">renewable energy solutions</a> transforms a familiar childhood novelty into a device capable of powering small electronics.</p>



<p>Detailed in a study published in the journal <em>Device</em>, this groundbreaking generator marks a major advancement. Furthermore, it showcases an efficient and sustainable method to meet modern energy needs.</p>



<h2 class="wp-block-heading" id="h-the-genesis-of-an-idea">The genesis of an idea</h2>



<p>The drinking bird toy demonstrates thermodynamics through a simple mechanism. It features two glass bulbs connected by a tube, filled with methylene chloride. </p>



<p>When its felt-covered head dips into water, evaporation creates a pressure difference that moves the liquid up the tube, simulating drinking. Intriguingly, this action inspired researchers to explore converting <a href="https://www.earth.com/news/light-can-drive-water-evaporation-without-heat/" target="_blank" rel="noreferrer noopener">evaporation</a> energy into electricity.</p>



<p>Hao Wu, a professor at <a href="https://www.scut.edu.cn/en/" target="_blank" rel="noreferrer noopener">South China University of Technology</a> and the first author of the study, recalls the eureka moment, "I still feel surprised and excited when witnessing the actual results." </p>



<p>The realization that this toy could transcend its educational purpose to become a source of energy was pivotal. </p>



<p>At the time, Wu was a postdoc in Prof. Zuankai Wang’s group at The Hong Kong Polytechnic University (<a href="https://www.polyu.edu.hk/" target="_blank" rel="noreferrer noopener">PolyU</a>). He recognized the potential to transform mechanical energy from evaporation into electricity.</p>



<h2 class="wp-block-heading" id="h-the-drinking-bird-engine">The drinking bird engine</h2>



<p>By reengineering the drinking bird toy, the team developed the "drinking bird triboelectric hydrovoltaic generator." </p>



<p>This innovative device incorporates triboelectric nanogenerator modules on either side of a drinking bird engine, capturing the mechanical energy produced by the toy's motion. </p>



<p>Remarkably, this setup can generate over 100 volts from just 100 milliliters of water. It surpasses other water-based <a href="https://www.earth.com/news/this-solar-powered-device-produces-both-clean-water-and-clean-energy/" target="_blank" rel="noreferrer noopener">electricity generation</a> techniques and maintains power for several days.</p>



<p>Furthermore, this generator serves to power various small electronics, such as liquid crystal displays (LCDs), temperature sensors, and calculators. However, the team encountered a significant challenge: overcoming friction in the generator. </p>



<p>By cleverly integrating patterned fibers as charge transfer materials within the triboelectric nanogenerator modules, they managed to reduce friction and significantly enhance device efficiency.</p>



<h2 class="wp-block-heading" id="h-looking-ahead">Looking ahead</h2>



<p>The research team, led by Prof. Zuankai Wang, is not resting on their laurels. Eagerly, they aim to design a custom drinking bird engine, departing from commercial toys. Their ambitious goal is a system better optimized for converting water evaporation into electrical energy.</p>



<p>"Additionally, we will explore various application opportunities for this device with the ultimate aim of delivering a practical product that can be used in our daily lives," says Wang. This statement underscores the project's goal to weave this technology into the fabric of everyday life.</p>



<p>This study not only underscores the untapped potential of simple physical principles but also sets a precedent for sustainable energy generation. </p>



<p>By reimagining a toy's playful mechanics for powering electronics, the researchers have introduced new paths for renewable energy solutions. This emphasizes the crucial role of innovation in addressing future energy challenges.</p>



<p>The full study was published in the journal <em><a href="https://www.cell.com/device/fulltext/S2666-9986(24)00108-X" target="_blank" rel="noreferrer noopener">Device</a></em>.</p>

Transforming the drinking bird toy into a power generator

Leveraging the whimsical drinking bird toy as their muse, scientists...

<p>A new study has shaken up our understanding of early childhood development. They found that a simple set of five factors, called Thrive 5, when present in an <a href="https://www.earth.com/news/nutrition-for-neurons-the-role-of-breast-milk-in-shaping-our-brains/" target="_blank" rel="noreferrer noopener">infant's first year</a>, sets them up for a lifetime of healthy development and success.</p>



<p>Right from the get-go, it's clear: To unlock a child's potential, these five conditions are non-negotiable. This discovery could drastically change how we approach parenting and public health.</p>



<h2 class="wp-block-heading" id="h-focus-of-the-thrive-5">Focus of the Thrive 5</h2>



<p>The researchers studied over 200 <a href="https://www.earth.com/news/conscious-awareness-when-does-our-sense-of-purpose-emerge/" target="_blank" rel="noreferrer noopener">infants</a> and their mothers, investigating how supportive factors in early development affect the brain. At age 3, the children underwent brain scans, along with evaluations of their cognitive, social, and emotional development. </p>



<p>The findings were remarkable: regardless of background, children who received stronger support in the Thrive 5 areas displayed healthier brain development, stronger cognitive skills, and better social-emotional well-being.</p>



<p>"When they have access to these basic supports, even in the face of adverse environments, it enhances their brain development, cognition (measures of IQ) and social-emotional <a href="https://www.earth.com/news/music-promotes-social-development-in-infants/" target="_blank" rel="noreferrer noopener">development</a>,” said Dr. Joan Luby of <a href="https://wustl.edu" target="_blank" rel="noreferrer noopener">Washington University in St. Louis</a>, one of the study's lead researchers.</p>



<h2 class="wp-block-heading" id="h-what-is-the-thrive-5">What is the "Thrive 5"?</h2>



<p>The Thrive 5 encompasses these crucial elements for a thriving baby:</p>



<h3 class="wp-block-heading">1. Nutrition</h3>



<ul>
<li><strong>Breast milk benefits</strong>: If possible, breast milk is recommended as the primary source of nutrition. It's perfectly tailored to meet your baby's needs, providing the right balance of nutrients, antibodies, and hormones to support healthy development.<br></li>



<li><strong>Formula as an alternative</strong>: For those who cannot or choose not to breastfeed, infant formula is a safe and nutritious alternative. It's important to choose a formula that meets your baby's nutritional needs and to follow preparation instructions carefully.</li>
</ul>



<h3 class="wp-block-heading">2. Stimulation</h3>



<ul>
<li><strong>Interactive play</strong>: Engage with your baby through playful interactions, facial expressions, and gestures. This not only strengthens your bond but also stimulates your baby's cognitive and emotional development.<br></li>



<li><strong>Language exposure</strong>: Talk, read, and <a href="https://www.earth.com/news/mothers-can-use-singing-to-engage-with-infants/" target="_blank" rel="noreferrer noopener">sing</a> to your baby often. Exposure to language from an early age boosts cognitive development and can improve future language skills.<br></li>



<li><strong>Sensory opportunities</strong>: Provide a variety of textures, sounds, and visual stimuli to explore. Sensory play supports brain development and helps your baby learn about their environment.</li>
</ul>



<h3 class="wp-block-heading">3. Safety</h3>



<ul>
<li><strong>Physical safety</strong>: Ensure your home is baby-proofed to protect against potential hazards. A secure environment allows your baby to explore safely as they grow.<br></li>



<li><strong>Emotional security</strong>: A stable and loving environment where caregivers are responsive and sensitive to a baby's needs helps to build trust and emotional well-being.</li>
</ul>



<h3 class="wp-block-heading">4. Positive Caregiving</h3>



<ul>
<li><strong>Responsive care</strong>: Be attentive to your baby's cues and respond with love and consistency. Responsive caregiving supports emotional bonding and secure attachment.<br></li>



<li><strong>Nurturing attention</strong>: Regular cuddles, smiles, and positive interactions reinforce your baby's sense of safety and belonging.</li>
</ul>



<h3 class="wp-block-heading">5. Regular sleep</h3>



<ul>
<li><strong>Consistent routines</strong>: Establishing regular sleep patterns and routines helps regulate your baby's circadian rhythms, crucial for overall health and well-being.<br></li>



<li><strong>Sleep environment</strong>: Create a calm, comfortable sleeping environment to promote uninterrupted sleep, which is essential for growth and development.</li>
</ul>



<h2 class="wp-block-heading" id="h-making-the-thrive-5-a-reality">Making the Thrive 5 a reality</h2>



<p>"The Thrive Factor provides a solid foundation for healthy development. It has been underappreciated in primary care just how malleable the brain is to experience," Dr. Luby notes.</p>



<p>Moreover, the researchers acknowledge the challenges many families face in providing these vital elements to their <a href="https://www.earth.com/news/maternal-chemical-signals-help-infants-bond-with-strangers/" target="_blank" rel="noreferrer noopener">infants</a>. </p>



<p>Dr. Barch emphasizes how factors like poverty and unsafe living conditions make it difficult for even the most dedicated parents. "If you’ve never suffered from financial adversity, you don’t understand how hard that makes life," Barch states.</p>



<h2 class="wp-block-heading" id="h-study-significance">Study significance</h2>



<p>While the importance of each individual factor is established, this study is pioneering in how it frames them together for maximum impact.</p>



<p>"The novelty here is putting them all together and thinking of them as a constellation of things that are necessary and important for a <a href="https://www.earth.com/news/male-babies-talk-more-than-females-during-the-first-year/" target="_blank" rel="noreferrer noopener">child</a> to be able to thrive" says Dr. Deanna Barch, another key researcher on the project.</p>



<p>This study arms pediatricians, policymakers, and parents with a powerful tool. It shows that even when circumstances are challenging, prioritizing the Thrive 5 can lay the foundation for a child's bright future.</p>



<h2 class="wp-block-heading" id="h-let-s-give-every-baby-the-chance-to-thrive-5">Let's give every baby the chance to thrive (5)</h2>



<p>The Thrive 5 has the potential to revolutionize our approach to child development. Supporting families through education about the Thrive 5 and policy changes that address inequality is vital. </p>



<p>As Dr. Barch stresses, "We need to make it so families can have the resources necessary to provide these core things to kids because it’s going to have such a big impact on kids’ <a href="https://www.earth.com/news/caregiver-speech-shapes-infant-language-development/" target="_blank" rel="noreferrer noopener">development</a> across the course of their lifespan.”</p>



<p>By embracing the Thrive 5, we can create a future where all children have the opportunity to reach their full potential.</p>



<p>The study is published in <a href="https://doi.org/10.1001/jamapediatrics.2024.0143" target="_blank" rel="noreferrer noopener">JAMA Pediatrics</a>.</p>

Five scientifically proven steps for thriving infant development

A new study has shaken up our understanding of early...

<p>Hydrogen, or H2, is the most abundant element in the entire universe. Scientists have long suspected that hydrogen gas was the key energy source for <a href="https://www.earth.com/news/scientists-may-have-learned-how-earth-got-its-water/" target="_blank" rel="noreferrer noopener">Earth</a>'s earliest lifeforms. But the question was <em>how</em>?</p>



<p>Living things need a way to convert energy sources into usable forms. For our bodies, that means breaking down food to power everything we do. For the first cells, the challenge was figuring out how to utilize hydrogen.</p>



<p>New insights from teams across Germany and Asia point to a surprisingly simple answer. The research suggests that alkaline hydrothermal vents could be the missing link.</p>



<h2 class="wp-block-heading" id="h-hydrothermal-vents-and-the-origin-of-life">Hydrothermal vents and the origin of life</h2>



<p>Hydrothermal vents are openings in the sea floor where geothermally heated water emerges. They're found in places where the Earth's tectonic plates are moving apart or where volcanic activity is present. </p>



<p>This hot, mineral-rich water, which can reach temperatures exceeding 752°F, mixes with the cold, deep-sea water around it.</p>



<p>Despite the extreme conditions -- immense pressure, scalding temperatures, and no light -- these vents teem with diverse life forms. </p>



<p>Scientists are constantly intrigued by life thriving in such harsh conditions. They believe these vents could reveal how <a href="https://www.earth.com/news/origins-life-simple-molecules/" target="_blank" rel="noreferrer noopener">Earth's life started</a>.</p>



<h2 class="wp-block-heading" id="h-hydrogen-gas-in-pushing-electrons">Hydrogen gas in pushing electrons</h2>



<p>So, how do the deep-sea creatures survive and even flourish? The research helps us understand one of the secrets to life at these vents: harvesting energy from hydrogen gas. </p>



<p>Think of hydrogen gas as a kind of fuel for these microorganisms. But there's a catch. To extract energy from hydrogen, cells have to do something that seems to defy nature -- they have to move electrons in an energetically "uphill" direction.</p>



<p>"In order to harvest energy, cells first have to push the electrons from H2 energetically uphill," explains Max Brabender, one of the study's authors. "That is like asking a river to flow uphill instead of downhill, so cells need engineered solutions."</p>



<h2 class="wp-block-heading" id="h-role-of-iron-in-earth-s-origin">Role of iron in Earth's origin</h2>



<p>The secret to this uphill energy transfer? It turns out, a humble metal – iron – may have played a starring role. </p>



<p>At the alkaline pH of these vents, scientists discovered that iron, produced by natural processes in this environment, could split hydrogen and send those energy-carrying electrons in the right direction. </p>



<p>No fancy enzymes or complex cellular machinery were needed!</p>



<p>"Metals provide answers," says <a href="https://www.mpi-marburg.mpg.de/martina-preiner">Martina Preiner</a> from the Max Planck Institute (MPI)&nbsp;. "At the <a href="https://www.earth.com/news/new-clues-from-asteroid-bennu-about-the-origins-of-life/" target="_blank" rel="noreferrer noopener">onset of life</a>, metals under ancient environmental conditions can send the electrons from H2 uphill, and we can see relicts of that primordial chemistry preserved in the biology of modern cells." But metals alone are not enough. </p>



<p>"H2 needs to be produced by the environment as well," adds co-first author Delfina Pereira from Preiner's lab.</p>



<h2 class="wp-block-heading" id="h-insights-from-hydrogen-gas-study">Insights from hydrogen gas study</h2>



<p>"Several different theories have proposed how the environment might have pushed electrons energetically uphill...we have identified a process that could not be simpler and that works in the natural conditions of hydrothermal vents," notes William F. Martin, lead researcher from the <a href="https://www.hhu.de/en/" target="_blank" rel="noreferrer noopener">University of Düsseldorf</a>.</p>



<p>"That hydrogen can make metallic iron out of minerals is no secret," says Harun Tüysüz, an expert for high-tech materials at the <a href="https://www.kofo.mpg.de" target="_blank" rel="noreferrer noopener">Max-Planck-Institut für Kohlenforschung Mülheim</a> and co-author of the study. </p>



<p>"Many processes in the chemical industry use H2 to make metals out of minerals during the reaction." The surprise is that nature does this too, especially at hydrothermal vents, and that this naturally deposited iron could have played a crucial role in the <a href="https://www.earth.com/news/sulfur-may-have-played-key-role-origin-of-life-on-earth/" target="_blank" rel="noreferrer noopener">origin of life</a>.</p>



<h2 class="wp-block-heading" id="h-study-significance">Study significance</h2>



<p>The beauty of this discovery lies in its simplicity. The same process found in modern microbes might have been the key that kick-started life itself billions of years ago. </p>



<p>It creates an image of Earth's earliest lifeforms. These organisms didn't rely on complex machinery. Instead, they tapped into a natural mechanism to gather the essential energy and make a crucial leap towards life.</p>

<p>As discussed above, hydrothermal vents, the seafloor's mysterious geysers, captivate scientists and oceanographers with their extreme conditions and unique ecosystems. These fascinating features of the deep sea offer insights into the origins of life, the limits of biological endurance, and the potential for life beyond Earth.</p>



<h3 class="wp-block-heading" id="h-definition-and-formation-of-hydrothermal-vents">Definition and formation of hydrothermal vents</h3>



<p>Hydrothermal vents are fissures on the planet's surface from which geothermally heated water discharges. Located primarily on mid-ocean ridges, these vents form when seawater seeps through cracks in the ocean floor, heats up by the magma beneath the Earth's crust, and then gushes back into the ocean, creating plumes of mineral-rich water that support a diverse range of life forms.</p>



<p>The process begins with tectonic plates diverging at mid-ocean ridges, creating new oceanic crust and allowing seawater to penetrate the Earth's crust. As the water interacts with the hot magma, it becomes superheated, dissolving minerals and metals from the surrounding rocks. </p>



<p>This superheated, mineral-rich water, which can reach temperatures of up to 400°C (752°F), then rises and exits through the seafloor, cooling rapidly as it mixes with the ocean water, causing the dissolved minerals to precipitate and form chimney-like structures around the vents.</p>



<h3 class="wp-block-heading" id="h-living-on-hydrogen-gas-in-extreme-conditions">Living on hydrogen gas in extreme conditions</h3>



<p>Hydrothermal vents are home to unique ecosystems that thrive in conditions once thought to be inhospitable to life. These ecosystems rely not on photosynthesis, which is impossible in the dark depths of the ocean, but on chemosynthesis. </p>



<p>Microorganisms at the base of the vent ecosystem convert the chemical energy from the vent minerals into organic compounds, serving as the primary producers and supporting a diverse community of organisms, including giant tube worms, clams, and unique species of fish and crustaceans.</p>



<h3 class="wp-block-heading" id="h-past-present-and-future-significance">Past, present, and future significance</h3>



<p>Hydrothermal vents have significant scientific, economic, and environmental importance. They provide unique natural laboratories for studying the origins of life, as the chemosynthetic processes observed at vents are similar to those that might have occurred on the early Earth. </p>



<p>Additionally, hydrothermal vents are of interest for bioprospecting, as organisms adapted to extreme conditions often produce unique enzymes and compounds that can be of pharmaceutical and industrial use.</p>



<p>Moreover, vents play a crucial role in the geochemical cycles of the ocean, influencing the composition of seawater and the global distribution of minerals. However, they also face threats from deep-sea mining and climate change, raising concerns about the need for their conservation and sustainable management.</p>



<h3 class="wp-block-heading" id="h-challenges-and-opportunities">Challenges and opportunities</h3>



<p>Studying hydrothermal vents poses significant technical challenges due to their deep, remote locations and the extreme conditions present. However, advances in deep-sea exploration technologies, such as remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs), are enabling more detailed and frequent studies of these fascinating systems.</p>



<p>The exploration of hydrothermal vents not only expands our knowledge of Earth's processes and life in extreme environments but also enhances our understanding of the potential for life on other planetary bodies. For instance, Jupiter's moon Europa and Saturn's moon Enceladus, both of which have subsurface oceans, may host hydrothermal vent-like conditions, suggesting the possibility of life beyond Earth.</p>



<h3 class="wp-block-heading" id="h-implications-and-future-study">Implications and future study</h3>



<p>In summary, hydrothermal vents, with their extreme conditions and unique ecosystems, continue to fascinate and challenge our understanding of life and the Earth's processes. </p>



<p>As we explore these enigmatic features of the deep sea, we uncover the secrets of our own planet and open the door to discovering the potential for life in the far reaches of the solar system. </p>



<p>The study of hydrothermal vents represents a thrilling intersection of geology, biology, and astrobiology, offering insights and opportunities that stretch the imagination and drive forward the frontiers of science.</p>

<p>The impact of global warming in the United States is far more severe than previously thought. This is caused, in large part, by the heat index. While an increase of about <a href="https://www.earth.com/news/emissions-gap-report-paris-pledges-are-not-enough-to-avoid-catastrophe/" target="_blank" rel="noreferrer noopener">3 degrees Fahrenheit</a> due to global warming might seem minimal, the actual "experience" of the heat tells a different story.</p>



<p>The research, centered on Texas's climate data from the summer of 2023, reveals that the heat index -- the measure of how hot it really feels, considering humidity -- has risen about three times faster than the actual temperature. </p>



<p>On the most sweltering days, this means Texans are enduring feels-like temperatures between 8 and 11 degrees Fahrenheit hotter than what would be expected without the <a href="https://www.earth.com/news/red-alert-climate-warning-issued-after-2023-smashed-heat-records/" target="_blank" rel="noreferrer noopener">influence of climate change</a>.</p>



<h2 class="wp-block-heading" id="h-rethinking-the-heat-index-and-heat-stress">Rethinking the heat index and heat stress</h2>



<p>David Romps, a professor of earth and planetary science at the <a href="https://www.berkeley.edu/" target="_blank" rel="noreferrer noopener">University of California, Berkeley</a>, and the study's lead author, highlights a significant communication gap in conveying the real dangers of rising temperatures. </p>



<p>Traditional measures, including the heat index itself, fall short of accurately capturing the heat stress experienced by individuals. This discrepancy is primarily caused by not fully accounting for the <a href="https://www.earth.com/news/humans-are-substantially-changing-the-seasons-of-the-ocean/" target="_blank" rel="noreferrer noopener">extremes of temperature</a> and humidity we now face. </p>



<p>Forgetting these factors often leads to a dangerous underestimation of the risks of hyperthermia and heat-related mortality.</p>



<p>The findings from Texas echo a broader, national concern. For instance, Arizona reported a staggering 50% increase in heat-associated deaths from 2022 to 2023, with the majority of these deaths occurring among individuals aged 50 years and older. </p>



<h2 class="wp-block-heading" id="h-insights-for-surviving-the-new-heat">Insights for surviving the "new" heat</h2>



<p>These statistics underscore the urgent need for action to address the escalating risks posed by climate change. Romps stresses the imperative to halt <a href="https://www.earth.com/news/unbearable-heat-could-make-some-parts-of-the-world-uninhabitable/" target="_blank" rel="noreferrer noopener">further warming</a> by ceasing the burning of fossil fuels. </p>



<p>"I mean, the obvious thing to do is to cease additional warming, because this is not going to get better unless we stop burning fossil fuels," Romps asserts.</p>



<p>"That's message No. 1, without doubt. We have only one direction we can really be taking the planet's average temperature, and that's up. And that's through additional burning of fossil fuels. So that's gotta stop and stop fast," he explained.</p>



<p>In the face of these challenges, Romps offers practical advice for coping with the heat, particularly for those without access to air conditioning. </p>



<p>Strategies like seeking shade, using water, and employing fans can significantly aid in preventing hyperthermia. Simple actions, such as wetting one's skin and staying hydrated, can provide essential relief.</p>



<p>"You can coat yourself in water. Get a wet rag, run it under the faucet, get your skin wet and get in front of a fan. As long as you are drinking enough water and you can keep that skin wetted in front of the fan, you're doing a good thing for yourself," Romps advised.</p>



<h2 class="wp-block-heading" id="h-new-method-to-measure-the-heat-index">New method to measure the heat index</h2>



<p>Romps, also an atmospheric physicist, alongside Yi-Chuan Lu, a graduate student turned postdoctoral fellow, embarked on a crucial journey to redefine our understanding of heat stress in the face of global warming. </p>



<p>Their research pivots around the heat index, a measure devised in 1979 to gauge the stress exerted on the human body by combined heat and humidity. </p>



<p>Despite its longstanding use, Romps identified a <a href="https://www.earth.com/news/asymmetric-warming-between-day-and-night-impacts-all-life-on-earth/" target="_blank" rel="noreferrer noopener">critical gap</a>. As mentioned previously, original calculations used for measuring the heat index did not account for the extreme heat and humidity levels we encounter today.</p>



<p>Addressing this gap, Romps and Lu advanced the calculation of the heat index, extending its applicability to encompass even the most severe heatwaves, such as those Texas experienced in the summer of 2023. </p>



<h2 class="wp-block-heading" id="h-true-impact-of-the-scorching-summer-sun">True impact of the scorching summer sun</h2>



<p>This enhancement reveals that the traditional method of extrapolating heat index values by the National Weather Service (<a href="https://www.nws.gov" target="_blank" rel="noreferrer noopener">NWS</a>), part of the National Oceanic and Atmospheric Administration (<a href="https://www.noaa.gov" target="_blank" rel="noreferrer noopener">NOAA</a>), significantly underestimates the stress experienced during extreme conditions.</p>



<p>The duo's findings come from a detailed case study of Texas, chosen due to its alarming heat index values. A particular focus was on Houston’s Ellington Airport, where on <a href="https://www.earth.com/news/july-was-earths-hottest-month-in-120000-years/" target="_blank" rel="noreferrer noopener">July 23, 2023</a>, they recorded a heat index of a staggering 167 degrees Fahrenheit (75 C), with global warming contributing to 12 degrees Fahrenheit (6 C) of this figure. </p>



<p>“It sounds completely insane,” Romps said. “It’s beyond the physiological capacity of a young, healthy person to maintain a standard core temperature. We think it’s hyperthermic, but survivable.”</p>



<h2 class="wp-block-heading" id="h-wet-bulb-temperature-directly-impacts-survival">Wet bulb temperature directly impacts survival</h2>



<p><a href="https://www.earth.com/news/what-temperature-threshold-can-the-human-body-handle/" target="_blank" rel="noreferrer noopener">This survivability</a>, as Romps points out, hinges on the body's ability to cool itself through evaporative cooling -- a process demanding significant cardiovascular effort due to intense sweating. </p>



<p>The generally accepted threshold for maximum survivable temperature is a "wet bulb temperature" of 35 degrees Celsius, which is equivalent to a skin temperature when sweating of 95 degrees Fahrenheit, close to the average person’s core <a href="https://www.earth.com/news/depression-may-be-linked-to-higher-body-temperatures/" target="_blank" rel="noreferrer noopener">body temperature</a>. </p>



<p>Their research suggests that while this may not necessarily result in death for young, healthy adults, it does pose a serious risk of hyperthermia.</p>



<p>"Heat index is very much like the wet bulb thermometer, only it adds the metabolic heat that a human has that a thermometer does not have," Romps explained, expanding on the concept of the wet bulb temperature.</p>



<p>"We think if you kept your skin wet and you were exposed to 167 degrees, even though we're approaching something like a setting on the oven, you'd still be alive. Definitely not happy. But alive," he emphasized.</p>



<h2 class="wp-block-heading" id="h-climate-change-and-the-new-normal">Climate change and the new normal</h2>



<p>Looking to the future, Romps acknowledges the increasing risk of hyperthermic conditions due to <a href="https://www.earth.com/news/climate-change-earth-energy-imbalance-temperature-rise/" target="_blank" rel="noreferrer noopener">climate change</a>, without attempting to predict specific occurrences. </p>



<p>The study’s broader implication warns of a future where, if current fossil fuel consumption continues, a significant portion of the world's population could face life-threatening heat stress levels, especially those who are not young and healthy, or those working or exposed to direct sunlight.</p>



<p>In light of these findings, Romps is keen on investigating other regions using the refined heat index scale, expecting to uncover <a href="https://www.earth.com/news/2024-is-expected-to-exceed-the-1-5c-warming-limit/" target="_blank" rel="noreferrer noopener">similar trends</a> across the globe. </p>



<p>"If humanity goes ahead and burns the fossil fuel available to it, then it is conceivable that half of Earth's population would be exposed to unavoidably hyperthermic conditions, even for young, healthy adults," Romps said. </p>



<p>"People who aren't young and healthy would be suffering even more, as would people who are laboring or are out in the sun -- all of them would be suffering potentially life-threatening levels of heat stress," he concluded.</p>



<h2 class="wp-block-heading" id="h-global-implications-of-a-hotter-heat-index">Global implications of a hotter heat index</h2>



<p>In summary, the research conducted by David Romps and Yi-Chuan Lu serves as a crucial wake-up call to the underestimated impacts of <a href="https://www.earth.com/news/climate-change-accelerated-in-the-last-decade-making-it-the-hottest-on-record/" target="_blank" rel="noreferrer noopener">global warming</a> on heat stress, highlighting the inadequacies of current heat index calculations to capture the extremities of today's climate conditions. </p>



<p>By extending the heat index calculations to cover all possible combinations of temperature and humidity, their work focuses on the severe, yet survivable, conditions experienced in Texas and around the U.S., offering a glimpse into a future where such extremities could become commonplace.</p>



<p>Their eye-opening study emphasizes the urgency for immediate action to curb fossil fuel consumption while advocating for the adoption of innovative strategies to adapt to the unavoidable increases in global temperatures, thereby safeguarding communities against the escalating threat of heat stress.</p>

Heat index, how hot it 'feels' outside, is rising faster than actual temperatures

The impact of global warming in the United States is...

<p>Have you ever wondered why some <a href="https://www.earth.com/news/coffee-improve-group-performance/" target="_blank" rel="noreferrer noopener">groups</a> click instantly, while others struggle to find their rhythm? Scientists think they may have found an answer, and it lies in the power of social bonding.</p>



<p>We humans are inherently social. Our lives revolve around building connections, being part of groups, and finding our place in the world. This study explores the importance of social bonding and the adaptability of our brains in social settings. </p>



<h2 class="wp-block-heading" id="h-social-bonding-among-groups">Social bonding among groups</h2>



<p>To investigate, scientists at <a href="https://english.bnu.edu.cn" target="_blank" rel="noreferrer noopener">Beijing Normal University</a> in China devised a clever experiment. They brought together 176 trios of participants who were strangers prior to the study. Within each group, a leader was democratically selected, leaving them with a leader and two followers in each trio.</p>



<p>Some groups were then assigned to go through a bonding exercise designed to foster a sense of connection which included icebreakers, sharing preferences, etc. Others started the task directly, with no time for bonding. </p>



<p>Next, the groups played a few games that involved making decisions that could benefit their own group or potentially harm others. Scientists were monitoring everyone's brain activity during the games using a non-invasive technique. </p>



<h2 class="wp-block-heading" id="h-changes-in-the-brain">Changes in the brain</h2>



<p>Groups that went through the <a href="https://www.earth.com/news/strong-social-bonds-promote-healthy-behaviors/" target="_blank" rel="noreferrer noopener">bonding</a> session communicated more freely and rapidly. Conversations flowed smoother, with less of that awkward pausing as people searched for the right words.</p>



<p>This communication boost was especially noticeable between leaders and followers who had bonded. It was like they were on the same wavelength.</p>



<p>The scientists found that two brain areas linked to social interaction went into overdrive – and in sync – for leaders and followers who had formed a bond. </p>



<p>This was especially true in two areas of the brain: the right dorsolateral prefrontal cortex (rDLPFC) and the right temporoparietal junction (rTPJ). These areas are the social hubs in our brains, and when leaders and followers in bonded groups interacted, these areas lit up in sync. </p>



<p>In other words, bonding might be the secret that helps leaders anticipate what their followers are thinking, leading to a smoother-running team dynamic.</p>



<h2 class="wp-block-heading" id="h-implications-of-social-bonding-in-groups">Implications of social bonding in groups</h2>



<p>The researchers suggest that social bonding might be the reason some <a href="https://www.earth.com/news/group-decisions-information-loss/" target="_blank" rel="noreferrer noopener">teams</a> work incredibly well together. When we form close connections with those around us, information seems to flow more easily. </p>



<p>Crucially, this effect seems especially powerful in teams with clear hierarchies – those with defined leaders and followers. </p>



<p>Having that bond means more effective communication and a greater understanding between a leader and those they guide.</p>



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



<p>Before we start planning mandatory team trust falls, let's acknowledge that this research is still in its early stages. There are a few caveats worth considering.</p>



<p>The participants were all East Asian Chinese. Culture plays a huge role in how we form bonds and view leadership, so it'll be interesting to see if the results hold true in other societies.</p>



<p>The groups communicated mainly via text, leaving out crucial elements like facial expressions, tone of voice, and all the unspoken signals we rely on.</p>



<h2 class="wp-block-heading" id="h-the-power-of-connection">The power of connection</h2>



<p>Even with its limitations, this research highlights why team-building and icebreakers can have a real impact. </p>



<p>"Social bonding increases information exchange and prefrontal neural synchronization selectively among individuals with different social statuses, providing a potential neurocognitive explanation for how social bonding facilitates the hierarchical structure of human groups," said the researchers.  </p>



<p>Investing time and energy into genuinely connecting with those you work with - especially if you're the one leading the team - might give your team a brain-boosting edge.</p>



<p>After all, we evolved as social beings, and our brains seem to work their best when we feel a sense of belonging.</p>



<p>The study is published in the journal <a href="https://doi.org/10.1371/journal.pbio.3002545" target="_blank" rel="noreferrer noopener">PLOS Biology</a>. </p>

<p>In an unparalleled feat of cosmic cartography, astronomers have unveiled the most expansive map yet of the universe's active supermassive black holes, known as quasars.</p>



<p>Moreover, this new map catalogs a mind-boggling <a href="https://www.earth.com/wp-content/uploads/2024/03/quasar-map_1.3-million_bright-cosmos_ESA_1m.jpg" target="_blank" rel="noreferrer noopener">1.3 million quasars</a> across the visible universe. Consequently, it represents a significant advance in our quest to unravel the mysteries of <a href="https://www.earth.com/news/dark-matter-does-not-exist-universe-27-billion-years-old-study/" target="_blank" rel="noreferrer noopener">dark matter</a> and the fabric of the cosmos.</p>



<p>Quasars - supermassive black holes at galaxy centers - are ironically the brightest <a href="https://www.earth.com/news/feeding-frenzy-study-reveals-the-eating-habits-of-black-holes/" target="_blank" rel="noreferrer noopener">cosmic objects</a>, illuminating space's darkest corners. </p>



<p>Further, the new map tracks quasars across space and time. It notably features those from when the universe was merely 1.5 billion years old, offering a stark contrast to its current age of 13.7 billion years.</p>



<h2 class="wp-block-heading" id="h-a-map-like-no-other">A map like no other</h2>



<p>David Hogg, a senior research scientist at the Flatiron Institute’s <a href="https://astronyc.org/" target="_blank" rel="noreferrer noopener">Center for Computational Astrophysics</a> in New York City and a professor of physics and data science at <a href="https://www.nyu.edu/" target="_blank" rel="noreferrer noopener">New York University</a>, emphasizes the uniqueness of this quasar catalog. </p>



<p>"This catalog offers us a three-dimensional map of the universe's largest-ever volume," Hogg explains. Unlike other catalogs, this one may not have the highest number of quasars or the finest quality measurements. However, it excels in covering an unprecedented expanse of the universe.</p>



<p>The map, unveiled in <em>The Astrophysical Journal</em>, is the creation of Hogg's team, featuring lead author Kate Storey-Fisher, a postdoctoral researcher at Spain's <a href="https://dipc.ehu.eus/en">Donostia International Physics Center</a>. It's based on data from the European Space Agency’s Gaia telescope, which, while mainly mapping the Milky Way, also detects quasars and <a href="https://www.earth.com/news/black-holes-shaped-the-universe-before-galaxies-existed/" target="_blank" rel="noreferrer noopener">galaxies</a> beyond.</p>



<p>Storey-Fisher noted the significance of their work. "We've achieved measurements of early universe matter clustering that rival those from major international survey projects -- a remarkable feat considering our data came as a 'bonus' from the Gaia project, primarily focused on the Milky Way," she said.</p>



<h2 class="wp-block-heading" id="h-quasars-and-the-mystery-of-dark-matter">Quasars and the mystery of dark matter</h2>



<p>Quasars illuminate dark matter's mysteries and the universe's expansion, revealing how dark matter clusters around them. </p>



<p>Consequently, this map has sparked diverse scientific investigations. Researchers are exploring topics ranging from the cosmic web's formation to the distribution of cosmic voids. Additionally, they are examining our solar system's movement through space.</p>



<h2 class="wp-block-heading" id="h-from-gaia-to-the-cosmos">From Gaia to the cosmos</h2>



<p>The team's work was enhanced by Gaia's third <a href="https://www.earth.com/news/gaia-mission-has-obtained-new-details-about-two-billion-stars/" target="_blank" rel="noreferrer noopener">data release</a>, featuring 6.6 million quasar candidates, and data from NASA’s Wide-Field Infrared Survey Explorer and the Sloan Digital Sky Survey. </p>



<p>This approach helped filter non-quasar objects and accurately measure quasar distances. They also created a map to identify areas where dust, stars, and other obstacles could block views of quasars, crucial for accurate interpretation.</p>



<h2 class="wp-block-heading" id="h-a-universal-map-beyond-stars">A universal map beyond stars</h2>



<p>Hogg reflected on the broader significance of their work. "This quasar catalog exemplifies the fruitful outcomes of astronomical projects. Gaia was tasked with mapping our galaxy's stars, yet it inadvertently provided us with a universal map through the discovery of millions of quasars," Hogg explained.</p>



<p>This monumental mapping effort enhances our understanding of the cosmos. It also exemplifies the unexpected discoveries that can emerge from scientific inquiry, paving the way for future explorations of the universe's mysteries.</p>



<h2 class="wp-block-heading">More about supermassive black holes</h2>



<p>As discussed above, supermassive black holes are among the most fascinating and extreme objects in the universe.</p>



<h3 class="wp-block-heading">Unimaginable mass</h3>



<p>Supermassive black holes, located at the centers of galaxies, can have masses millions to billions of times greater than that of the Sun. For example, the supermassive black hole at the center of the Milky Way, known as Sagittarius A*, has a mass about 4.6 million times that of the Sun.</p>



<h3 class="wp-block-heading">Invisible giants</h3>



<p>Despite their massive size, supermassive black holes themselves are invisible because they trap all light within their event horizon. However, they can be detected through their interactions with surrounding matter, such as the accretion disks of glowing gas that often orbit them, and the powerful jets of particles they can emit.</p>



<h3 class="wp-block-heading">Foundational role in galaxies</h3>



<p>Supermassive black holes are believed to play a critical role in the formation and evolution of galaxies. There is a strong correlation between the mass of a supermassive black hole and various properties of its host galaxy, suggesting a deep, intrinsic link between galaxies and their central black holes.</p>



<h3 class="wp-block-heading">Quasars and active galactic nuclei</h3>



<p>Some supermassive black holes are extraordinarily bright because they actively accrete matter from their surroundings at high rates. These actively feeding black holes can power quasars and other types of active galactic nuclei (AGN), making them some of the most luminous objects in the universe, visible across vast cosmic distances.</p>



<h3 class="wp-block-heading">Gravitational waves</h3>



<p>The <a href="https://www.earth.com/news/supermassive-binary-black-holes-secrets-revealed/">merger</a> of supermassive black holes can produce ripples in the fabric of spacetime, known as gravitational waves. Detecting these waves from supermassive black hole mergers requires future space-based observatories, as these events produce low-frequency waves that cannot be detected by current Earth-based facilities.</p>



<h3 class="wp-block-heading">Einstein's predictions</h3>



<p>The study of supermassive black holes and their effects on spacetime and matter around them has provided strong evidence in support of Albert Einstein's theory of general relativity. Observations of stars orbiting closely around Sagittarius A* have confirmed predictions of general relativity with high precision.</p>



<h3 class="wp-block-heading">Mysterious formation of supermassive black holes </h3>



<p>The formation of supermassive black holes remains an area of active research. One theory suggests they could form from the collapse of extremely massive clouds of gas in the early universe, while another proposes they grow from smaller black holes that merge and accumulate mass over time.</p>



<h3 class="wp-block-heading">Event Horizon Telescope achievements</h3>



<p>In 2019, the EHT collaboration released the first-ever "image" of a supermassive black hole, located in the galaxy M87. This historic achievement was actually a picture of the black hole's shadow against its surrounding accretion disk, providing direct visual evidence of a black hole's existence.</p>



<p>These facts highlight just how much supermassive black holes are at the heart of many of the most significant and intriguing astrophysical phenomena in the universe.</p>



<p>The full study was published in <a href="https://iopscience.iop.org/article/10.3847/1538-4357/ad1328" target="_blank" rel="noreferrer noopener">The Astrophysical Journal</a>.</p>

<p>In a development that might soon render snow shovels and salt redundant, <a href="https://drexel.edu/" target="_blank" rel="noreferrer noopener">Drexel University</a> researchers have unveiled a self-heating concrete technology poised to transform winter infrastructure in cold regions. </p>



<p>This innovative concrete, infused with phase-change materials, can autonomously maintain warmth, effectively fending off snow, sleet, and freezing rain. </p>



<p>This advancement promises significant reductions in both the environmental and economic costs associated with winter weather management. Furthermore, it extends the lifespan of concrete surfaces by preventing the wear and tear caused by <a href="https://www.earth.com/news/arctic-sea-ice-cycles-show-impacts-of-climate-change/" target="_blank" rel="noreferrer noopener">freeze-thaw</a> cycles and deicing chemicals.</p>

<p>Located on Drexel University's campus, two experimental concrete slabs have been successfully demonstrating this technology for over three years. </p>



<p>These slabs, each measuring 30 inches by 30 inches, have consistently resisted winter's harshness without any manual intervention. They showcase the potential for a future where icy sidewalks and roads are things of the past.</p>



<h2 class="wp-block-heading" id="h-the-science-of-self-heating-surfaces">The science of self-heating surfaces</h2>



<p>The driving force behind this innovation is the desire to create infrastructure that is both environmentally friendly and resilient against the rigors of northern <a href="https://www.earth.com/news/why-winters-are-getting-colder-while-world-is-getting-warmer/" target="_blank" rel="noreferrer noopener">winters</a>. </p>



<p>The United States, particularly its northern region, spends billions annually on snow and ice removal, not to mention the substantial costs of repairing winter-damaged roads. </p>



<p>According to Dr. Amir Farnam, associate professor at Drexel's College of Engineering, the key to prolonging the life of concrete surfaces lies in their ability to remain above freezing temperatures during winter, thus eliminating the detrimental freeze-thaw cycles.</p>



<h2 class="wp-block-heading" id="h-bringing-self-seating-concrete-into-the-real-world">Bringing self-seating concrete into the real world</h2>



<p>Over five years, Dr. Farnam's team refined the self-heating concrete mix to lessen the need for plowing and salting. Their breakthrough showed its effectiveness in real-world conditions, thanks to low-temperature liquid paraffin. </p>



<p>This phase-change material releases heat during the liquid-to-solid transition, allowing the concrete to maintain surface temperatures between 42- and 55-degrees Fahrenheit for up to 10 hours in <a href="https://www.earth.com/news/natural-antifreeze-could-revolutionize-the-future-of-concrete/" target="_blank" rel="noreferrer noopener">freezing conditions</a>. This prevents ice formation and melts snow efficiently.</p>



<p>The researchers tested two methods for adding phase-change material to concrete. The first method involved pre-treating lightweight aggregate with paraffin. The second method involved mixing micro-capsules of paraffin directly into the concrete. </p>



<p>Over two years and through 32 freeze-thaw events and heavy snowfalls, both methods successfully kept surface temperatures above freezing. This prevented the structural damage typically caused by expansion and contraction.</p>



<h2 class="wp-block-heading" id="h-comparing-warmth">Comparing warmth</h2>



<p>The study revealed two key findings about concrete with phase-change materials. Concrete incorporating phase-change material in lightweight aggregate sustained warmth longer. Conversely, concrete with microencapsulated paraffin warmed up faster but also cooled down more quickly. </p>



<p>This suggests the former is better for deicing, releasing heat slowly, especially in <a href="https://www.earth.com/news/study-reveals-cause-last-winters-brutal-u-s-cold-snap/" target="_blank" rel="noreferrer noopener">sub-zero temperatures</a>. </p>



<p>However, effectiveness varies with factors like ambient temperature and snowfall rate. Although the self-heating concrete can't fully prevent heavy snow accumulation, it's very effective for snowfalls under two inches, providing a greener alternative to road salting.</p>



<h2 class="wp-block-heading" id="h-continuous-improvement-and-long-term-impact">Continuous improvement and long-term impact</h2>



<p>As the Drexel team continues to refine this technology, their research underscores the potential of self-heating concrete to significantly reduce the incidence of freeze-thaw cycles, enhancing the durability of concrete surfaces compared to traditional materials. </p>



<p>This promising development marks a significant stride toward more sustainable and resilient infrastructure capable of withstanding the challenges of winter weather.</p>



<p>The study is published in the journal <em><em><a href="https://ascelibrary.org/doi/10.1061/JMCEE7.MTENG-17048" target="_blank" rel="noreferrer noopener">Materials in Civil Engineering</a></em></em>.</p>

The rise of self-heating concrete technology

In a development that might soon render snow shovels and...

<p>A groundbreaking study led by the <a href="https://www.ulisboa.pt/en">University of Lisbon</a> raises the startling possibility that the Atlantic Ocean might one day vanish, consumed by an expanding subduction zone known as the "Ring of Fire."</p>



<p>According to the research, currently nestled beneath the Strait of Gibraltar - the sliver of sea separating Spain from Morocco - this subduction zone could extend westward into the Atlantic, potentially initiating the ocean basin's gradual closure.&nbsp;</p>



<h2 class="wp-block-heading" id="h-process-may-already-be-underway-nbsp">Process may already be underway&nbsp;</h2>



<p>This significant geological shift is predicted to occur "soon" in geological terms, roughly in 20 million years, suggesting that humanity might witness this monumental change.</p>



<p>Subduction zones, where one <a href="https://www.earth.com/news/major-volcanic-events-linked-to-the-slowing-of-tectonic-plates/">tectonic plate</a> is forced beneath another, are hotspots for intense seismic events. Led by Professor João Duarte at the University of Lisbon's Faculty of Sciences, the study emphasizes that the formation of new subduction zones could herald the eventual disappearance of <a href="https://www.earth.com/news/discovery-ancient-ocean-floor-surrounds-the-earths-core/">entire oceans</a>, a process that might already be underway with the Atlantic.&nbsp;</p>



<p>"We have good reason to think that the Atlantic is starting to close," Duarte said. "Subduction zones are what cause the oceans to close, by pulling their ocean floor back into the mantle, bringing the continents together."</p>



<h2 class="wp-block-heading" id="h-potential-for-subduction-invasion-nbsp">Potential for subduction invasion&nbsp;</h2>



<p>The Strait of Gibraltar, which is just 10 miles wide, marks the junction of the Eurasian and African Plates. Within this subduction zone, the African plate is diving beneath the Eurasian plate, stirring seismic activity and heightening <a href="https://www.earth.com/news/earthquakes-have-long-lasting-impacts-on-forests/">earthquake</a> risks.&nbsp;</p>



<p>Presently, the subduction zone's activity is described as "sleeping," with plate movement into the Earth's mantle occurring at a notably sluggish pace. However, Duarte and his team speculate that subduction zones have the potential to expand, a phenomenon they term "subduction invasion."</p>



<h2 class="wp-block-heading" id="h-atlantic-ocean-could-vanish-gradually">Atlantic Ocean could vanish gradually </h2>



<p>Though the Gibraltar subduction zone currently spans about 125 miles in length and reaches depths exceeding 350 miles, it's among the smallest globally. Yet, Duarte suggests it could stretch to approximately 500 miles in 20 million years.&nbsp;</p>



<p>Through computer simulations tracing the subduction zone's development from the Oligocene epoch (34 million to 23 million years ago) into the future, the researchers anticipate its westward migration through the narrow Strait of Gibraltar over the coming 20 million years.&nbsp;</p>



<p>These models forecast the emergence of a new Atlantic subduction system, akin to the Pacific Ocean's Ring of Fire, which gradually diminishes the ocean floor and draws continents closer, potentially leading to the Atlantic's disappearance.</p>



<h2 class="wp-block-heading" id="h-fundamental-process-in-earth-s-evolution-nbsp">Fundamental process in Earth's evolution&nbsp;</h2>



<p>"The results suggest that the arc will propagate farther into the Atlantic after a period of quiescence," the authors wrote. "The models also show how a subduction zone starting in a closing ocean can migrate into a new opening ocean through a narrow oceanic corridor."</p>



<p>"Subduction invasion is likely a common mechanism of subduction initiation in Atlantic-type oceans and a fundamental process in the recent geological evolution of Earth."</p>



<p>This discovery also underscores the active nature of the Gibraltar subduction and its implications for regional seismic hazards. The devastating 1755 Great Lisbon Earthquake, which virtually obliterated Lisbon and claimed approximately 12,000 lives, serves as a stark reminder of the area's seismic vulnerability, necessitating ongoing preparedness efforts.</p>



<h2 class="wp-block-heading" id="h-new-evidence-of-the-atlantic-subduction-system-nbsp">New evidence of the Atlantic subduction system&nbsp;</h2>



<p>This research marks the first illustration of such an invasion occurring directly. A sophisticated, gravity-driven 3-D model forecasts the expansion of a subduction zone beneath the Gibraltar Strait into the Atlantic, laying the groundwork for an Atlantic subduction system. </p>



<p>Duarte highlighted the technological advancements enabling this discovery: “Subduction invasion is inherently a three-dimensional process that requires advanced modeling tools and supercomputers that were not available a few years ago."</p>



<p>"We can now simulate the formation of the Gibraltar Arc with great detail and also how it may evolve in the deep future.”</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1130/G51654.1" target="_blank" rel="noreferrer noopener"><em>Geology</em></a>.</p>

Why the Atlantic Ocean may ultimately vanish

A groundbreaking study led by the University of Lisbon raises...

<p>Namibia's fairy circles have long captivated the imagination with their enigmatic presence in the dry grasslands on the <a href="https://www.earth.com/news/mysterious-fairy-circles-are-likely-caused-by-termite-activity/" target="_blank" rel="noreferrer noopener">Namib Desert's fringe</a>. These peculiar, circular, bald patches have puzzled scientists for decades, inspiring numerous theories about their formation. </p>



<p>A recent study by researchers from the <a href="https://www.uni-goettingen.de/en/1.html" target="_blank" rel="noreferrer noopener">University of Göttingen</a> in Germany and <a href="https://www.bgu.ac.il/en/" target="_blank" rel="noreferrer noopener">Ben Gurion University</a> in Israel delves deep into this mystery, challenging previously held beliefs and providing new insights into the phenomenon.</p>



<p>The study, published in the journal <em>Perspectives in Plant Ecology, Evolution and Systematics</em>, focuses on the lifecycle of freshly germinated grass within these circles and its struggle for survival. </p>



<h2 class="wp-block-heading" id="h-studying-namibia-s-mysterious-fairy-circles">Studying Namibia's mysterious fairy circles</h2>



<p>Contrary to the popular termite theory, the research reveals that these grass patches wither away due to a critical lack of water, not termite damage. </p>



<p>The top 10 to 12 centimeters of soil, described as a "death zone," proves inhospitable for the young grass, which dies just 10 to 20 days following rainfall.</p>



<p>This research involved meticulous fieldwork, analyzing 500 individual grass plants across <a href="https://www.earth.com/news/fairy-circles-cause-revealed/" target="_blank" rel="noreferrer noopener">four Namib regions</a>. </p>



<p>Through detailed measurements of root and leaf lengths, statistical analyses, and the comparison of photographic evidence, coupled with extensive soil moisture measurements during the 2023 and 2024 rainy seasons, the team uncovered startling findings. </p>



<h2 class="wp-block-heading" id="h-perennial-grasses-vs-new-sprouts">Perennial grasses vs. new sprouts</h2>



<p>The topsoil within fairy circles dries out significantly faster and remains drier compared to surrounding areas, creating an environment where freshly sprouted grass cannot thrive.</p>



<p>In sharp contrast, the study observed that perennial grass clumps around the fairy circles flourish, benefiting from deeper soil moisture levels. These clumps, with well-developed root systems extending 20 to 30 centimeters below the surface, exhibit a remarkable ability to quickly absorb water after rainfall. </p>



<p>"With their well-developed root system, these clumps of grass soak up the water particularly well. After the rain, they have a huge competitive advantage over the freshly germinated grasses in the fairy circle," explains Dr. Stephan Getzin from Göttingen University's Ecosystem Modelling Department.</p>



<p>"The new grass only loses a small amount of water via transpiration from its small leaves, resulting in insufficient ‘suction power’ to pull new water from deeper soil layers," he continued.</p>



<h2 class="wp-block-heading" id="h-importance-of-soil-moisture-in-fairy-circles">Importance of soil moisture in fairy circles</h2>



<p>The researchers also discovered that water's physical conductivity is highest in the soil's upper layers during the first 20 days after rain, favoring the established clumps of grass that primarily draw water from this zone. </p>



<p>"This is the cause of the death of the new grass in the fairy circle. Continuous soil moisture measurements over several years support this conclusion. This is because the soil water in the fairy circle only decreases noticeably quickly with the strengthening and regrowth of the surrounding grass after rain," Gertzin explained further.</p>



<p>This phenomenon further exacerbates the difficulties faced by newly germinated grasses within the fairy circles, leading to their eventual death. </p>



<p>Continuous soil moisture tracking over several years has reinforced these findings, highlighting the role of fairy circles as crucial water reserves for the drought-stricken grasses of the <a href="https://www.earth.com/image/dust-blows-off-the-coast-of-namibia-over-the-atlantic-ocean/" target="_blank" rel="noreferrer noopener">Namib</a>.</p>



<h2 class="wp-block-heading" id="h-disproving-the-popular-termite-theory">Disproving the popular termite theory</h2>



<p>Interestingly, the study also challenges the sand termite theory, which suggests that termites feeding on the roots of new grass contribute to the formation of fairy circles. The researchers provide a compelling argument, backed by systematic data, debunking this theory. </p>



<p>They emphasize the lack of concrete evidence linking termite activity to the creation of these circles, critiquing the misinterpretation of cited research within the termite theory's support base.</p>



<p>The fairy circles, according to Getzin and his colleague Dr. Hezi Yizhaq, represent a fascinating example of "swarm intelligence" or self-organization among plants, as they adapt to scarce resources in arid environments. This survival strategy, manifested in the circles' round shape, maximizes soil water availability, showcasing nature's ingenuity in the face of adversity.</p>



<h2 class="wp-block-heading" id="h-one-step-closer-to-solving-this-namibian-mystery">One step closer to solving this Namibian mystery</h2>



<p>In summary, this study has significantly advanced our understanding of Namibia's fairy circles, though many questions still remain. The scientists debunked the long-held termite theory and highlighted the crucial role of water scarcity in their formation. </p>



<p>Through rigorous fieldwork and analysis, researchers have demonstrated that one significant cause of these enigmatic patterns results from the natural struggle for survival in harsh desert conditions, where perennial grasses outcompete newly germinated ones for limited water resources. </p>



<p>This intriguing research highlights the adaptive strategies of desert flora and underscores the complexity and beauty of natural ecosystems, revealing the intricate balance that sustains life in one of the planet's most unforgiving landscapes.</p>



<p>The full study was published in the journal <em><a href="https://www.sciencedirect.com/science/article/pii/S1433831924000039?via%3Dihub" target="_blank" rel="noreferrer noopener">Perspectives in Plant Ecology, Evolution and Systematics</a>.</em></p>

<p>Celebrated every year on March 20, World Sparrow Day is a special occasion dedicated to raising awareness about the protection of sparrows and other birds that share our environment. This day is a call to action - a reminder of the delicate beauty around us that must be protected.</p>



<h2 class="wp-block-heading" id="h-origins-of-world-sparrow-day">Origins of World Sparrow Day</h2>



<p>World Sparrow Day can be traced back to the collaborative efforts of the <a href="https://www.natureforever.org/" target="_blank" rel="noreferrer noopener">Nature Forever Society of India</a>, founded by Mohammed Dilawar, the Eco-Sys Action Foundation of France, and numerous other global entities. </p>



<p>While the day is named after sparrows, it represents a broader mission - to draw attention to the beauty and biodiversity of all common birds that cohabit our urban and rural spaces.&nbsp;</p>



<p>It was Mohammed Dilawar's passion for conserving house sparrows in Nashik that sparked the official campaign. The inaugural World Sparrow Day was celebrated in 2010, marking the beginning of an ongoing global effort to conserve birdlife.</p>



<p>This initiative has provided a vital platform for bird conservationists to network, share ideas, and foster global <a href="https://www.earth.com/news/half-of-the-worlds-bird-species-are-now-in-decline/">awareness</a> about species that are often overlooked yet integral to our ecosystems.</p>



<h2 class="wp-block-heading" id="h-the-plight-of-the-sparrow">The plight of the sparrow</h2>



<p>House sparrows, known for their cheerful chirping and presence in green patches and backyards of urban areas, are facing threats that push them towards extinction.&nbsp;</p>



<p>Factors such as noise pollution, lack of nesting sites, pesticide usage, and food scarcity have been identified as significant contributors to their declining numbers. Despite their once common presence, sparrows now struggle to survive in environments that have evolved without considering their needs.</p>



<h2 class="wp-block-heading" id="h-fascinating-facts-about-sparrows-nbsp">Fascinating facts about sparrows&nbsp;</h2>



<p>Sparrows may be small, but they play a significant role in our ecosystems and cultures. Here are some interesting facts about sparrows:</p>



<h3 class="wp-block-heading" id="h-adaptability">Adaptability</h3>



<p>Sparrows are incredibly adaptable to various environments, which is why they thrive in diverse habitats, including urban areas. Their ability to <a href="https://www.earth.com/news/birds-have-mastered-the-art-of-coexisting-in-a-changing-world/">live close to humans</a> and make use of human-made structures for nesting and feeding is remarkable.</p>



<p>The house sparrow (Passer domesticus) is one of the most widely distributed bird species in the world, found on every continent except Antarctica.</p>



<h3 class="wp-block-heading" id="h-cultural-significance">Cultural significance</h3>



<p>Sparrows have been symbols of companionship, simplicity, and joy across various cultures throughout history. In ancient Egypt, they were believed to catch the souls of the recently deceased. Greek mythology associated them with Aphrodite, the goddess of love, due to their perceived lustfulness.</p>



<h3 class="wp-block-heading" id="h-social-creatures">Social creatures</h3>



<p>Sparrows are incredibly social birds. They live in colonies known as flocks and often engage in social activities such as dust or water bathing and "social singing," where groups of sparrows sing together in a chorus.</p>



<h3 class="wp-block-heading" id="h-dietary-flexibility">Dietary flexibility</h3>



<p>While primarily seed-eaters, sparrows are opportunistic feeders and can consume a variety of foods based on availability. Their diet can include insects, fruits, and even discarded food from humans in urban areas.</p>



<h3 class="wp-block-heading" id="h-distinctive-features">Distinctive features</h3>



<p>Although often perceived as plain, both male and female sparrows have distinctive <a href="https://www.earth.com/news/savannah-sparrows-are-losing-their-unique-adaptations-in-the-bay-area/">markings</a>. Male house sparrows, for example, can be identified by their gray heads, white cheeks, black bibs, and rufous neck – whereas females and young sparrows sport a more uniform brown plumage.</p>



<h3 class="wp-block-heading" id="h-nesting-habits">Nesting habits</h3>



<p>Sparrows are quite inventive when it comes to nesting. They prefer to nest in close proximity to humans, often utilizing nooks and crannies in buildings, as well as natural cavities. They can also reuse and adapt old nests of other birds.</p>



<h3 class="wp-block-heading" id="h-vocal-variety">Vocal variety</h3>



<p>Sparrows have a wide range of calls and songs which they use to communicate with each other. Their songs are primarily used by males to attract mates and establish territories.</p>



<h3 class="wp-block-heading" id="h-declining-sparrow-populations">Declining sparrow populations</h3>



<p>Despite their adaptability, the population of house sparrows has been declining in many parts of the world. This <a href="https://www.earth.com/news/new-report-confirms-that-bird-species-are-steadily-declining/">decline</a> is attributed to factors such as urbanization, pollution, and the loss of their natural habitats.</p>



<h3 class="wp-block-heading" id="h-symbolism-and-superstition">Symbolism and superstition</h3>



<p>Sparrows have been subjects of various superstitions and symbols. In some cultures, a sparrow flying into one's home symbolizes good luck and happiness.</p>



<p>In Greek mythology, the sparrow was the sacred bird of Aphrodite, the goddess of love, and symbolized true love and spiritual connection.</p>



<h2 class="wp-block-heading" id="h-a-growing-movement">A growing movement</h2>



<p>Over the years, World Sparrow Day has witnessed increasing participation from people across the globe. Individuals and communities are taking proactive steps by creating bird nests and shelters for sparrows and other common birds. Such initiatives not only aid in the conservation of these species but also reconnect people with nature.</p>



<p>World Sparrow Day serves as a reminder of the beauty and significance of sparrows and other common birds. It encourages us to observe, appreciate, and protect these tiny avian companions who share our spaces but often go unnoticed.

Tiny but mighty: The significance of World Sparrow Day

Celebrated every year on March 20, World Sparrow Day is...

<p>A fossil discovered over a century ago has been confirmed as the oldest <a href="https://www.earth.com/wp-content/uploads/2024/03/Trachelosaurus-fischeri_skeleton-comparison_Swiss-Journal-Paleontology_1m.jpg" target="_blank" rel="noreferrer noopener">long-necked marine reptile</a>. A team of international scientists re-examined the <em>Trachelosaurus fischeri</em> fossil, transforming our knowledge of Triassic marine life.</p>



<p>This discovery by <a href="https://www.naturkundemuseum-bw.de/en/" target="_blank" rel="noreferrer noopener">State Museum of Natural History Stuttgart</a> provides a thrilling new chapter in the ancient marine ecosystems.</p>



<h2 class="wp-block-heading" id="h-discovery-of-trachelosaurus-fischeri">Discovery of <em>Trachelosaurus fischeri</em></h2>



<p>The story of <em>Trachelosaurus fischeri </em>began in 19th century Germany, where its fossilized remains were discovered. However, its unusual anatomy caused confusion among scientists. For decades, the true identity of this perplexing creature remained shrouded in mystery.</p>



<p>"Through research on Chinese fossils of the long-necked marine reptile <a href="https://www.earth.com/news/dinocephalosaurus-240-million-year-old-chinese-dragon-was-a-fierce-predator/" target="_blank" rel="noreferrer noopener">Dinocephalosaurus</a>, which I published with colleagues just a few weeks ago, we were able to solve the mystery of <em>Trachelosaurus fischeri</em>. The anatomy shows us that it is closely related to Dinocephalosaurus," explains <a href="https://www.stephanspiekman.com" target="_blank" rel="noreferrer noopener">Dr. Stephan Spiekman</a>, an expert on this group of animals.</p>



<p>"Trachelosaurus fischeri is the first fossil of this reptile group to be found outside of China. It is also the oldest long-necked marine <a href="https://www.earth.com/earthpedia-articles/are-chameleons-reptiles-yes-heres-why/" target="_blank" rel="noreferrer noopener">reptile</a> known to date."</p>



<h2 class="wp-block-heading" id="h-unique-features-of-trachelosaurus-fischeri">Unique features of <em>Trachelosaurus fischeri</em></h2>



<p>The fossil offers a tantalizing glimpse into the evolutionary past. Following are the peculiar details of its anatomy.</p>



<h3 class="wp-block-heading" id="h-disjointed-skeleton">Disjointed skeleton</h3>



<p>The partially disarticulated skeleton of <em>Trachelosaurus fischeri</em> provides valuable clues. It includes skull fragments, a substantial section of the spine, parts of the tail vertebrae, a well-preserved rib cage, sections of the pelvis, a femur, and even a possible foot bone. </p>



<p>These elements, though fragmented, give researchers a strong foundation for comparison with other early archosauromorphs.</p>



<h3 class="wp-block-heading" id="h-elongated-spine">Elongated spine</h3>



<p>Remarkably, <em>Trachelosaurus fischeri</em> boasts a long spine, with at least 21 neck vertebrae and 27 back vertebrae. This elongation is a hallmark of the tanysaurians. Furthermore, the ends of the spine's neural arches widen distinctively, unlike anything seen in other Triassic archosauromorphs. </p>



<h3 class="wp-block-heading" id="h-unusual-ribs">Unusual ribs</h3>



<p>The creature's neck ribs are equally bizarre with their short, forked design, never extending past the length of the vertebra they belong to. This is another unusual trait unseen in its close relatives.</p>



<h3 class="wp-block-heading" id="h-additional-clues">Additional clues</h3>



<p>The fossil's right premaxilla reveals long, slightly curved teeth devoid of serrations – a feature resembling some tanystropheids and trachelosaurids. </p>



<p>Moving beyond the head, <em>Trachelosaurus fischeri</em> lacks a some parts of the pelvis, and its femur is surprisingly stout without a bend. Its barrel-shaped torso and rounded ribs show that this creature was built for life in the water.</p>



<h2 class="wp-block-heading" id="h-survival-strategies">Survival strategies</h2>



<p>Scientists suspect its signature long neck was a crucial weapon in its hunting arsenal. With lightning-fast strikes, it likely ambushed unsuspecting prey. </p>



<p>Furthermore, the discovery of land-dwelling animal footprints near the <em>Trachelosaurus fischeri</em> fossil paints a dramatic scene. It's possible the reptile ventured too close to the shore, or perhaps violent weather washed it ashore into shallow waters. </p>



<p>These footprints reveal the ever-changing nature of prehistoric coastlines, where the boundaries blurred between land and sea. The mix of marine and terrestrial creatures in the same rock layer suggests a thriving and diverse ecosystem. </p>



<p>The coastal waters were likely a bountiful hunting ground for Trachelosaurus fischeri. Yet, these same waters carried a deadly risk, as its fossilized remains tragically attest.</p>



<h2 class="wp-block-heading" id="h-why-the-trachelosaurus-fischeri-fossil-matters">Why the Trachelosaurus fischeri fossil matters</h2>



<p>The discovery of <em>Trachelosaurus fischeri</em> reveals the astonishing resilience of life. After the devastating Permian-Triassic extinction event 252 million years ago, Earth's biodiversity took a massive hit. </p>



<p>Yet, remarkably, life bounced back. Unique creatures like long-necked <a href="https://www.earth.com/news/gondwana-ancient-reptile-species/" target="_blank" rel="noreferrer noopener">reptiles</a> evolved and thrived in the transformed marine world.</p>



<p>The story of <em>Trachelosaurus fischeri</em> is about more than just this single <a href="https://www.earth.com/news/280-million-year-old-fossil-of-tridentinosaurus-antiquus-proven-to-be-a-forgery/" target="_blank" rel="noreferrer noopener">fossil</a>. It reminds us that museum collections hold vast, untapped potential. Old specimens, sometimes overlooked, can unveil incredible secrets when studied with new perspectives and advanced techniques. </p>



<p>This fossil's century-long journey, from discovery to re-examination, highlights how museums and universities continue to unlock the mysteries of our planet's past.</p>



<p>The study is published in the <a href="https://doi.org/10.1186/s13358-024-00309-6" target="_blank" rel="noreferrer noopener">Swiss Journal of Palaeontology</a>.</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>

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



<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>



<p>The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.</p>



<p>As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.</p>



<p>The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.</p>

<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>



<p>The study was published in the journal <em><a href="https://www.nature.com/nataging" target="_blank" rel="noreferrer noopener">Nature Aging</a></em>.</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>

<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.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>
