<p>A recent analysis of the Sapphire Canyon mudstone core, drilled by NASA’s Perseverance rover in July 2024, adds new and convincing evidence to the ongoing search for life on Mars.</p>



<p>The study describes minerals and textures that - on Earth - are often linked to microbial activity. At the same time, the authors stress that some unknown, nonbiological chemistry could also explain the signals.</p>



<p>“This finding by Perseverance is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars,” said acting NASA Administrator Sean Duffy. </p>



<p>“NASA’s commitment to conducting Gold Standard Science will continue as we pursue our goal of putting American boots on Mars’ rocky soil.”</p>



<p>The core was taken from a rock named "<a href="https://www.earth.com/news/perseverance-rover-finds-best-evidence-yet-life-on-mars-cheyava-falls-rock/">Chevaya Falls</a>" in Neretva Vallis, an ancient river channel about a quarter mile wide that once fed Jezero Crater’s lake. </p>



<p>After drilling, <a href="https://www.earth.com/news/perseverance-rover-captures-a-surprise-dust-devil-while-taking-high-resolution-selfie-on-mars/">Perseverance</a> sealed the sample for possible return to Earth, where laboratory instruments can perform tests far beyond the rover’s onboard capabilities.</p>



<h2 class="wp-block-heading" id="h-inside-the-martian-mudstone">Inside the Martian mudstone</h2>



<p>Lead author Joel A. Hurowitz of <a href="https://www.stonybrook.edu/" target="_blank" rel="noreferrer noopener">Stony Brook University</a> (SBU) reports a fine-grained mudstone with circular reaction fronts informally called leopard spots, plus small nodules embedded in layered sediments.</p>



<p>Perseverance’s <a href="https://www.nasa.gov/centers-and-facilities/jpl/the-detective-aboard-nasas-perseverance-rover/" target="_blank" rel="noreferrer noopener">SHERLOC</a> and <a href="https://www.jpl.nasa.gov/news/heres-how-ai-is-changing-nasas-mars-rover-science/" target="_blank" rel="noreferrer noopener">PIXL</a> instruments mapped organic carbon with phosphate, iron, and sulfur arranged in distinct, repeating patterns.</p>



<p>Two minerals stand out: vivianite and greigite. Vivianite is an iron phosphate, while greigite is an iron sulfide associated with iron and sulfur cycling in oxygen-poor settings.</p>



<p>These features show up in rocks that settled from<a href="https://www.earth.com/news/wave-ripples-discovered-mars-surface-indicate-liquid-water-present-4-billion-years-ago/"> water</a>, not in lavas. The site on Mars lies along Bright Angel, a set of outcrops that preserve layers and veins consistent with slow changes after the mud was laid down.</p>



<p>Textures and chemistry point to low temperature reactions that reorganized elements already present in the mud. </p>



<p>That detail matters because low temperatures fit environments that life can handle, while very hot conditions tend to erase delicate signals.</p>



<h2 class="wp-block-heading" id="h-earth-microbes-leave-similar-traces">Earth microbes leave similar traces</h2>



<p>On Earth, vivianite often forms where microbes reduce iron in water-rich sediments and trap phosphorus in blue-green nodules. </p>



<p>Laboratory and field work document biologically mediated vivianite through extracellular electron transfer.</p>



<p><a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/greigite" target="_blank" rel="noreferrer noopener">Greigite</a> frequently appears where sulfate reducing bacteria drive chemistry in anoxic muds. In controlled experiments, greigite was detected only in live biotic setups after months of incubation.</p>



<p>The Martian rock shows rims rich in vivianite surrounding small cores enriched in greigite. That bullseye pattern matches a sequence of electron transfer reactions seen in some Earth sediments.</p>



<p>None of this proves metabolism happened in Bright Angel mud, but it shows the chemistry is right for it. That is a subtle point, and it is the reason scientists keep the language cautious.</p>



<h2 class="wp-block-heading" id="h-evidence-of-life-on-mars">Evidence of life on Mars</h2>



<p>A potential biosignature is a feature that might have a biological origin but still needs more data to rule out nonbiological sources. </p>



<p>NASA points mission teams and the public to the Confidence of Life Detection, or CoLD scale, which encourages staged claims and independent checks.</p>



<p>The CoLD mindset is simple in practice. First detect a signal, then exclude contamination, then tackle alternatives, and only then talk about life on Mars with high confidence.</p>



<p>The Bright Angel work sits early on that ladder. It clears several necessary steps but leaves demanding tests for the lab.</p>



<p>Organic compounds can also arrive by <a href="https://www.earth.com/news/what-meteorites-tell-us-about-their-birthplace-in-space/">meteorites</a> or form without biology. The authors note those routes and describe how future analyses could tell paths apart.</p>



<h2 class="wp-block-heading" id="h-organic-signals-but-no-certainty">Organic signals, but no certainty</h2>



<p>The Mars rover detected organic carbon in several targets within Bright Angel. Reaction fronts rimmed with vivianite surround cores richer in greigite, a pairing consistent with iron and sulfur cycling recorded in the paper.</p>



<p>Mineral veins include calcium sulfate, while the mudstone remains fine-grained and low in magnesium and manganese. There is no sign of intense heating that would reset the rock or scramble tiny textures.</p>



<p>The outcrop sits within layered sediments deposited by water flowing through Neretva Vallis. That channel spans roughly a quarter mile across, which implies sustained flow into Jezero’s ancient lake.</p>



<p>Low temperature context favors life-compatible chemistry, but it does not require life. Abiotic organics and <a href="https://www.earth.com/news/mineral-discovery-sheds-light-on-mars-fiery-past/">mineral</a> reactions can sometimes copy the same shapes and signals.</p>



<h2 class="wp-block-heading" id="h-not-proof-but-potential-life-on-mars">Not proof, but potential life on Mars</h2>



<p>“It’s not life itself,” said Nicky Fox, associate administrator for NASA’s Science Mission Directorate, stressing that this is a potential biosignature, not proof of life. The lead author echoed that caution.&nbsp;</p>



<p>“We cannot claim this is more than a potential biosignature,” said Hurowitz. Other officials also underscored the stakes and the limits.&nbsp;</p>



<p>“[But] this very well could be the clearest sign of life that we’ve ever found on Mars,” said Sean Duffy, acting NASA administrator. </p>



<p>Caution is not hedging for its own sake. It is how science avoids false alarms when the question is this important.</p>

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



<p>If the vivianite and greigite formed through microbe-like metabolisms, then <a href="https://www.earth.com/news/perseverance-rover-begins-steep-climb-up-martian-crater-rim-jezero-crater/">Bright Angel</a> captures a period when surface waters supported the same chemical strategies some cells use for energy today. </p>



<p>That would extend Mars's habitability into a window when this part of Jezero was still wet.</p>



<p>If abiotic paths made the same pattern, the rock still records redox organization of iron, sulfur, and phosphorus in Martian mud. That is a window into how the planet cycles key elements without biology.</p>



<p>Either outcome matters for the bigger story. Mars did not just dry out, it changed its chemistry over time, and these samples let researchers track that change layer by layer.</p>



<p>The work also flags what to measure next. Isotopes, microtextures, and the exact structure of <a href="https://www.earth.com/news/carbon-atoms-in-your-body-took-a-400000-light-year-journey-through-space/">carbon</a> in the core can separate metabolic signatures from chemical lookalikes.</p>



<h2 class="wp-block-heading" id="h-search-for-life-on-mars-moves-forward">Search for life on Mars moves forward</h2>



<p>The authors lay out lab experiments and field analogs on Earth to test whether nonbiological reactions can reproduce these textures and mineral pairings. </p>



<p>They also point to analyses that require the sample in a clean Earth lab, including isotope ratios that biology tends to skew.</p>



<p>Sample return planning will shape how fast those tests happen. Meanwhile, the rover can keep mapping where these features cluster and how they relate to other rock units nearby.</p>



<p>PIXL and SHERLOC have shown enough sensitivity to guide that search. The pairing of elemental maps and Raman detections gives a consistent picture that can be applied to other outcrops.</p>



<p>As new targets are logged, the CoLD framework will help communicate progress without getting ahead of the data. That is how a potential biosignature becomes a result people can trust.</p>

NASA announces discovery of life on Mars with high degree of confidence

A recent analysis of the Sapphire Canyon mudstone core, drilled by NASA’s Perseverance rover in July 2024, adds new and convincing evidence to the ongoing search for life on Mars. The study describes minerals and textures that - on Earth - are often linked to microbial activity. At the same time, the authors stress that some unknown, nonbiological chemistry could also explain the signals. “This finding by Perseverance is the closest we have ever come to discovering life on Mars. The identification of a potential biosignature on...

<p>Neanderthal DNA holds fascinating secrets about our evolutionary past, and offers us a glimpse into a time when humans coexisted with our now-extinct relatives.</p>



<p>One intriguing aspect of this shared history lies in the formation of our teeth - an area not often explored but equally revealing.</p>



<p>A global team of scientists from <a href="https://www.ucl.ac.uk/" target="_blank" rel="noreferrer noopener">University College London</a> (UCL), the Open University, Fudan University in China, Aix-Marseille University in France, and the National University of La Plata in Argentina has uncovered a variety of genetic variants that shape our teeth.</p>



<p>Among their findings is a particular gene, believed to be inherited from the Neanderthals, which was uniquely found in European participants of the study.</p>



<h2 class="wp-block-heading" id="h-neanderthal-insights-etched-on-our-teeth">Neanderthal insights etched on our teeth</h2>



<p>"Teeth can tell us a great deal about&nbsp;<a href="https://www.earth.com/news/human-evolution-was-shaped-by-competition-not-just-climate-change/" target="_blank" rel="noreferrer noopener">human evolution</a>, as well-preserved ancient teeth are particularly important to archaeologists, shedding light on milestones such as when we transitioned to cooked food and human tooth sizes began to shrink," explained study co-lead author Dr. Kaustubh Adhikari.</p>



<p>"But little is known about the genetic basis of variation within the modern human population on tooth size and shape, partly due to challenges in measuring teeth. We have now identified numerous genes that impact the development of our teeth, some of which are responsible for differences between ethnic groups."</p>



<p>Data for this study was gathered from 882 volunteers in Colombia, who were of mixed European, Native American, and African ancestry.</p>



<p>The researchers used 3D scans of dental plaster casts to derive measurements of the dental crown, the part of the tooth visible above the gums.</p>



<h2 class="wp-block-heading" id="h-teeth-across-ethnicities-a-genetic-perspective">Teeth across ethnicities: A genetic perspective</h2>



<p>The scientists compared the dental crown measurements with the participants' genetic information using an advanced approach called multiomics.</p>



<p>This unique method brings together numerous data sources to offer a comprehensive overview of the genetic impact on teeth.</p>



<p>The experts identified 18 genome regions that influence the size and shape of different groups of teeth. Among these, 17 had not been previously linked to tooth dimensions.</p>



<p>Interestingly, the researchers identified a gene that influences tooth development and was inherited from Neanderthals when they <a href="https://www.earth.com/news/neanderthals-and-humans-lived-side-by-side-45000-years-ago/" target="_blank" rel="noreferrer noopener">interbred with ancient humans</a>.</p>



<p>Carriers of this variant, found only in those of European descent, have thinner incisors leading to smaller teeth overall.</p>



<h2 class="wp-block-heading" id="h-from-anomalies-to-therapies">From anomalies to therapies</h2>



<p>Study first author Dr. Qing Li explained that the genes contributing to the normal variations of tooth sizes among healthy people can also lead to pathogenic variation, such as teeth failing to grow or other dental health conditions.</p>



<p>"We hope that our findings could be useful medically, if people with particular dental problems could undergo genetic tests to help in diagnosis, or if some dental anomalies could be treated one day with <a href="https://www.earth.com/news/new-technology-could-safely-treat-hundreds-of-genetic-diseases/" target="_blank" rel="noreferrer noopener">gene therapies</a>," said Dr. Li.</p>



<p>The study, however, points out that these genes may not have been evolutionarily selected for dental health advantages. Instead, they could have been chosen due to influences they have in other areas, with tooth shape differences resulting as a side effect.</p>



<p>The researchers had previously found that <a href="https://www.earth.com/news/neanderthal-genes-still-influence-modern-humans/" target="_blank" rel="noreferrer noopener">genes inherited from Neanderthals</a> might contribute to greater pain sensitivity and impact the shape of our noses.</p>



<p>The fascinating and complex interplay of genes and evolution continues to reveal unexplored aspects of our shared history and contribute to potential future medical advances.</p>



<h2 class="wp-block-heading" id="h-neanderthal-legacy-bridging-the-past-and-present">Neanderthal legacy: Bridging the past and present</h2>



<p>The genetic contributions of Neanderthals extend far beyond teeth, offering valuable clues about their role in shaping modern human traits. </p>



<p>Neanderthal <a href="https://www.earth.com/news/neanderthal-dna-is-more-common-in-people-with-autism/" target="_blank" rel="noreferrer noopener">DNA</a> has been linked to adaptations in areas such as pain perception and immune system function.</p>



<p>This latest research highlights how their genetic legacy has left an indelible mark on the development of our teeth, providing an evolutionary advantage - or in some cases, challenges.</p>



<p>The discovery of thinner incisors associated with Neanderthal-inherited genes raises questions about how these traits impacted survival and adaptation in ancient environments.</p>



<p>For instance, were these dental traits better suited for specific diets or environments? Ongoing research aims to uncover whether these genetic influences were incidental or served a greater evolutionary purpose.</p>



<p>By understanding how Neanderthal DNA continues to shape modern humans, scientists hope to unlock new pathways for both evolutionary biology and medical advances.</p>



<p>This knowledge could pave the way for tailored dental treatments, gene therapies, and even deeper insights into the interconnectedness of our genetic past and present.</p>

Neanderthal genes influence the development of modern teeth

Neanderthal DNA holds fascinating secrets about our evolutionary past, and...

<p>Tucked away in the vast expanse of our oceans, marine animals are capable of making remarkable journeys. Species like the green turtle and loggerhead turtle travel thousands of miles to return to the beaches where they were born to lay eggs.</p>



<p>Humpback whales migrate seasonally between cold, nutrient-rich waters where they feed and warm tropical waters where they breed and give birth.</p>



<p>Regardless of the species, marine animals use specific strategies to conserve energy. In a recent study, researchers have found a common theme among these animals - they all swim at similar relative depths when traveling and not feeding.</p>



<p>The research, led by experts from&nbsp;<a href="https://www.swansea.ac.uk/" target="_blank" rel="noreferrer noopener">Swansea University</a> and Deakin University, highlights how marine species minimize energy loss by swimming in a precise “sweet spot” below the surface.</p>



<h2 class="wp-block-heading" id="h-swimming-patterns-in-marine-animals">Swimming patterns in marine animals</h2>



<p>The study, led by&nbsp;Dr. Kimberley Stokes, Professor Graeme Hays, and&nbsp;Dr. Nicole Esteban, compared the swim depths of sea turtles, penguins, and whales across five countries.</p>



<p>The results showed that these <a href="https://www.earth.com/news/fentanyl-discovered-in-dolphins-what-it-means-for-marine-animals/" target="_blank" rel="noreferrer noopener">animals</a> consistently traveled at depths around&nbsp;three times their body size&nbsp;from the surface. This specific depth reduces the amount of energy that could be lost to wave formation and minimizes vertical travel distance - both of which contribute to efficient swimming.</p>



<p>Some semi-aquatic animals, like mink, swim closer to the surface, where wave generation causes significant energy waste. However, for air-breathing <a href="https://www.earth.com/news/alarming-climate-impacts-threaten-key-marine-species/" target="_blank" rel="noreferrer noopener">marine animals</a> that travel vast distances during migrations or daily commutes, adaptations to reduce energy costs are essential.</p>



<h2 class="wp-block-heading" id="h-long-standing-theory-confirmed-in-wild-animals">Long-standing theory confirmed in wild animals</h2>



<p>Physics has long predicted that drag from wave formation decreases significantly once an object travels at depths greater than three times its diameter. </p>



<p>Until now, proving this theory in wild animals posed a challenge due to limitations in tracking their movements.</p>



<p>The researchers overcame these challenges by using advanced tracking tools. They recorded near-surface swim depths within&nbsp;1.5 centimeters&nbsp;for&nbsp;penguins&nbsp;and&nbsp;loggerhead turtles.</p>



<p>Motion data and video footage from animal-borne cameras were combined with satellite tracking data for long-distance&nbsp;green turtle migrations. Data from previous studies on penguins and whales further supported the findings.</p>



<h2 class="wp-block-heading" id="h-marine-animals-optimize-swim-depth">Marine animals optimize swim depth</h2>



<p>The study was focused on animals traveling for extended distances while not foraging. These patterns showed a clear alignment with the theoretical optimal depths predicted by physics.</p>



<p>“There are of course examples where animal swim depth is driven by other factors, such as searching for prey, but it was exciting to find that all published examples of non-foraging air-breathing marine animals followed the predicted pattern,” said&nbsp;Dr. Kimberley Stokes, lead author of the study.</p>



<p>“This has rarely been recorded because of the difficulty in retrieving depth data from animals that migrate over large distances, so it was great to find enough examples to show a common relationship between swim depth and body size from animals across the size spectrum from 30 cm to about 20 m in length."</p>



<h2 class="wp-block-heading" id="h-implications-for-marine-travel-and-conservation">Implications for marine travel and conservation</h2>



<p>The discovery highlights the energy-efficient swimming strategies that marine animals have evolved over millions of years.</p>



<p>Penguins, whales, and turtles all utilize similar techniques, regardless of their size or species, to reduce energy costs during travel. </p>



<p>For animals covering thousands of kilometers in their lifetimes, such adaptations ensure survival and longevity.</p>



<p>Understanding these patterns could aid marine conservation efforts. Tracking swim depths could help identify migration routes, foraging patches, and key habitats for endangered species. </p>



<p>Conservationists may use this knowledge to create more effective strategies for protecting <a href="https://www.earth.com/news/ecosystem-behavior-earth-first-sea-creatures-stirring-water-drove-evolution/" target="_blank" rel="noreferrer noopener">marine animals</a> and their environments.</p>



<h2 class="wp-block-heading" id="h-relationship-between-swim-depth-and-body-size">Relationship between swim depth and body size</h2>



<p>The study’s findings provide a rare glimpse into the consistent relationship between body size and swim depth among marine animals. </p>



<p>From the smallest little penguin, measuring&nbsp;30 centimeters, to massive whales reaching&nbsp;20 meters, the same energy-efficient pattern emerges. </p>



<p>This highlights a universal principle of physics that governs the behavior of animals across vast size differences.</p>



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



<p>While the study focused on non-foraging travel of marine animals, future research may explore how swim depths change under <a href="https://www.earth.com/news/1-8-million-species-are-yet-to-be-identified-in-the-ocean/" target="_blank" rel="noreferrer noopener">different conditions</a>, such as varying water temperatures, ocean currents, or predator avoidance behaviors. </p>



<p>Advancements in tracking technologies will continue to improve our understanding of <a href="https://www.earth.com/news/deep-sea-mining-forms-dust-clouds-that-devastate-marine-life/" target="_blank" rel="noreferrer noopener">marine animal</a> movements and energy conservation strategies.</p>



<p>Marine mammals, birds, and reptiles have evolved to swim at precise depths that minimize energy loss. This new study confirms a long-held theory with real-world data, showing that <a href="https://www.earth.com/news/climate-change-is-impacting-marine-life-more-than-we-realized/" target="_blank" rel="noreferrer noopener">species</a> as different as turtles, penguins, and whales use the same strategy for efficient long-distance travel. </p>



<p>The work by Swansea and <a href="https://www.deakin.edu.au" target="_blank" rel="noreferrer noopener">Deakin</a> Universities opens new doors for understanding marine animal behavior and enhancing conservation efforts.</p>



<p>The study is published in the journal <a href="https://www.pnas.org/doi/10.1073/pnas.2413768121" target="_blank" rel="noreferrer noopener"><em>Proceedings of the National Academy of Sciences.</em></a></p>

Marine animals swim at the perfect depth to save energy

Tucked away in the vast expanse of our oceans, marine...

<p>In the abandoned lands surrounding the Chernobyl nuclear disaster site, something unexpected is happening. Amid decaying buildings and lingering radiation, Chernobyl dogs are not just surviving -- they're thriving. </p>



<p>These <a href="https://www.earth.com/news/chernobyl-wolves-have-evolved-resistance-to-cancer/" target="_blank" rel="noreferrer noopener">canine communities</a> are offering scientists a unique glimpse into how life adapts in one of the most hostile environments on Earth.</p>



<p>"Somehow, two small populations of dogs managed to survive in that highly toxic environment," head researcher <a href="https://www.publichealth.columbia.edu/profile/norman-kleiman-phd" target="_blank" rel="noreferrer noopener">Dr. Norman J. Kleiman</a> remarked.</p>



<p>Dr. Kleiman's team discovered significant genetic differences between two groups of dogs. </p>



<p>One group roams near the former Chernobyl reactors, while the other lives about 10 miles away in Chernobyl City. This finding suggests that these are two distinct populations that rarely interbreed.</p>



<h2 class="wp-block-heading" id="h-where-is-chernobyl-and-what-happened">Where is Chernobyl and what happened?</h2>



<p>The Chernobyl disaster happened on April 26, 1986, when a nuclear reactor at the Chernobyl Nuclear Power Plant in Ukraine exploded during a late-night safety test. </p>



<p>The test was supposed to simulate a power outage to see if the reactor could operate safely without electricity. But things went horribly wrong due to a mix of poor design, operator errors, and miscommunication. </p>



<p>A sudden power surge caused an uncontrollable reaction in Reactor 4, leading to a massive explosion that blew the reactor’s lid off and released tons of radioactive material into the atmosphere.</p>



<p>The immediate aftermath was chaotic. Fires raged, and radioactive smoke spread across Europe, making it one of the worst nuclear disasters in history. </p>



<h2 class="wp-block-heading" id="h-no-go-zone-becomes-a-dog-and-nature-haven">"No-go zone" becomes a dog and nature haven</h2>



<p>In the months and years that followed, the Chernobyl region became a no-go zone, with widespread environmental damage, health problems for people, dogs, and other animals exposed to radiation, and lingering fears of contamination.</p>



<p>In the first few days, radiation levels were so high that plants turned brown and died, and forests close to the reactor were devastated. </p>



<p>The "Red Forest," just a mile from the plant, got its name because the radiation killed the pine trees, turning them a reddish-brown before they withered away.</p>



<p>Wildlife suffered initially, with high radiation levels causing genetic mutations, reproductive problems, and a sharp decline in populations. </p>



<p>Birds and small mammals in the area were particularly affected, and aquatic life in nearby rivers and lakes also faced significant harm. </p>



<p>However, over time, the absence of humans in the Chernobyl Exclusion Zone allowed nature to rebound in surprising ways. </p>



<p>Without people, many species, including wolves, bears, rare animals like the <a href="https://www.earth.com/news/saving-przewalskis-horse-the-last-surviving-species-of-wild-horse/" target="_blank" rel="noreferrer noopener">Przewalski’s horse</a>, and the Chernobyl dogs discussed in this article have made the area home. </p>



<p>While radiation hotspots remain, wildlife has thrived in the absence of hunting, farming, and urban development, turning Chernobyl into an accidental refuge for nature.</p>



<h2 class="wp-block-heading" id="h-chernobyl-dogs-the-basics">Chernobyl dogs -- the basics</h2>



<p>The Chernobyl dogs are a heart-wrenching part of the disaster's legacy. After the 1986 nuclear meltdown explosion, many residents evacuated and were forced to leave their pets behind. </p>



<p>Among them were countless dogs, now descendants of those left behind, roaming the <a href="https://www.earth.com/news/chernobyls-exclusion-zone-wildlife-refuge/" target="_blank" rel="noreferrer noopener">Chernobyl Exclusion Zone</a>. </p>



<p>These dogs adapted to life in a harsh, radioactive environment, surviving extreme winters, limited food, and lingering radiation. </p>



<p>They live around abandoned villages and near the Chernobyl Nuclear Power Plant, often relying on scraps from workers and visitors.</p>



<p>Many of them form packs for protection and companionship, while some have surprisingly bonded with humans, especially the workers and scientists who still operate in the zone. </p>



<p>Efforts to help these dogs have increased over the years, with organizations stepping in to provide vaccinations, medical care, and even adoption programs to give some of them a chance at a new life outside the zone.</p>



<h2 class="wp-block-heading" id="h-genetic-clues-in-a-toxic-landscape">Genetic clues in a toxic landscape</h2>



<p>This study marks the first time scientists have delved into the genetic makeup of stray dogs living near the Chernobyl nuclear power plant. </p>



<p>"In addition to classifying the population dynamics within these dogs at both locations, we took the first steps towards understanding how chronic exposure to multiple environmental hazards may have impacted these populations," Dr. Kleiman explained.</p>



<p>According to Dr. Matthew Breen from <a href="https://www.ncsu.edu/" target="_blank" rel="noreferrer noopener">NC State</a>, "The overarching question here is: does an environmental disaster of this magnitude have a genetic impact on life in the region?" </p>



<p>By analyzing the dogs' DNA, the team identified 391 outlier regions in their genomes that differed between the two groups.</p>



<p>"Think of these regions as markers, or signposts, on a highway. They identify areas within the genome where we should look more closely at nearby genes," Dr. Breen explained.</p>



<p>Moreover, some of these markers are pointing to genes associated with genetic repair; specifically, with genetic repair after exposures similar to those experienced by the dogs in Chernobyl.</p>



<h2 class="wp-block-heading" id="h-much-still-unknown-about-the-chernobyl-dogs">Much still unknown about the Chernobyl dogs</h2>



<p>Despite these intriguing findings, the researchers caution that there's still much to learn. </p>



<p>"At this stage we cannot say for sure that any <a href="https://www.earth.com/news/dogs-labrador-retrievers-genetic-mutation-pomc-causes-hunger-obesity/" target="_blank" rel="noreferrer noopener">genetic alterations</a> are in response to the multigenerational and complex exposures; we have a lot more work to do to determine if that is the case," Dr. Breen added.</p>



<p>Ph.D. candidate Megan Dillion, a lead author of the study at NC State, is eager to dig deeper. </p>



<p>"The question we must answer now is why are there striking genetic differences between the two dog populations?" she said. </p>



<p>"Are the differences just due to genetic drift, or are they due to the unique environmental stressors at each location?"</p>



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



<p>The research has broader implications beyond <a href="https://www.earth.com/news/dogs-are-evolving-to-fit-the-modern-lives-of-humans/" target="_blank" rel="noreferrer noopener">the canine world</a>, because dogs are a sentinel species with much to teach us about human health.</p>



<p>"By teasing out whether or not the genetic changes we detected in these dogs are the canine genome's response to the exposures the populations have faced, we may be able to understand how the dogs survived in such a hostile environment and what that might mean for any population -- animal or human -- that experiences similar exposures," Breen concluded.</p>



<p>With 37 years having passed since the Chernobyl disaster, the <a href="https://www.earth.com/news/chernobyl-is-teeming-with-worms-resistant-to-radiation/" target="_blank" rel="noreferrer noopener">dangers of radiation</a> haven't faded. </p>



<p>The approximately 30-year-long half-lives of lingering radioisotopes mean the danger posed by radiation exposure is still very much real.</p>



<h2 class="wp-block-heading" id="h-complex-environmental-challenge">Complex environmental challenge</h2>



<p>Radiation isn't the only concern in the <a href="https://www.earth.com/news/frogs-exposed-to-radiation-show-no-signs-of-accelerated-aging/" target="_blank" rel="noreferrer noopener">Chernobyl Exclusion Zone</a>. The area is contaminated with chemicals, toxic metals, pesticides, and organic compounds left behind from years of cleanup efforts and decaying infrastructure. </p>



<p>"When radiation exposure is combined with a complex toxic chemical mixture of uncertain composition, there are very real human health concerns raised for the thousands of people who continue to work within the Exclusion Zone," Dr. Kleiman warned.</p>



<p>"Understanding the genetic and health impacts of these chronic exposures in the dogs will strengthen our broader understanding of how these types of <a href="https://www.earth.com/news/car-tires-shed-pollutants-that-are-especially-toxic-for-humans-and-wildlife/" target="_blank" rel="noreferrer noopener">environmental hazards</a> can impact humans and how best to mitigate health risks."</p>



<p>The research team plans to continue their work, hoping to unravel more of the genetic mysteries held by these resilient dogs. Their findings could pave the way for new insights into genetic adaptation in extreme environments.</p>



<h2 class="wp-block-heading" id="h-learning-from-chernobyl-and-its-dogs">Learning from Chernobyl and its dogs</h2>



<p>To sum it all up, the story of Chernobyl's dogs is a testament to life's resilience. These animals have carved out an existence in a place deemed uninhabitable. </p>



<p>Their journey raises thought-provoking questions: How do organisms adapt to such hostile conditions? What can we learn from their survival?</p>



<p>As scientists continue to explore these questions, one thing is clear: the dogs of Chernobyl have much to teach us. </p>



<p>Their survival offers a unique opportunity to understand the genetic impacts of environmental disasters, potentially informing how we protect both wildlife and ourselves in the face of similar challenges.</p>

Chernobyl dogs are responding to the toxic radiation with rapid genetic evolution

In the abandoned lands surrounding the Chernobyl nuclear disaster site,...

<p>Titanium has emerged as a key player in a recent carbon capture breakthrough that has been unveiled by scientists at Oregon State University.</p>



<p>This innovative research offers new hope in the battle against climate change, and showcases the power of out-of-the-box thinking and interdisciplinary collaboration.</p>



<p>By leveraging titanium’s affordability and abundance, the team has developed a promising method to capture carbon dioxide more efficiently. </p>



<p>Their discovery could pave the way for scalable, cost-effective solutions to reduce greenhouse gas levels in the atmosphere.</p>



<h2 class="wp-block-heading" id="h-transition-metals-and-carbon-capture">Transition metals and carbon capture</h2>



<p>The novel study, led by Professor May Nyman and Karlie Bach from Oregon State University College of Science, revolves around a vital mission: the reduction of <a href="https://www.earth.com/news/how-carbon-dioxide-travels-in-the-atmosphere/" target="_blank" rel="noreferrer noopener">carbon dioxide (CO<sub>2</sub>) levels in the atmosphere</a>.</p>



<p>The research is shedding new light on how carbon capture can be significantly improved - all the way down to the molecular level.</p>



<p>In 2021, Professor Nyman was chosen as the leader of one of nine direct air capture projects funded by the Department of Energy, according to a press <a href="https://news.oregonstate.edu/news/new-chemical-structures-developed-oregon-state-show-vastly-improved-carbon-capture-ability">release</a> from OSU.</p>



<p>Her team is studying how specific transition metal complexes can <a href="https://www.earth.com/news/new-tech-can-capture-carbon-dioxide-from-the-atmosphere/" target="_blank" rel="noreferrer noopener">capture carbon dioxide</a> from the air and transform it into metal carbonate, a compound often found in natural minerals.</p>



<p>What are these mysterious "transition metals"? They are a group of elements found near the center of the periodic table. Transition metals derive their name from the "transition" of their electrons between low and high energy states.</p>



<p>This electron movement results in the emission of distinctive colors, which adds a little splash of dazzle to the complex world of chemistry.</p>



<h2 class="wp-block-heading" id="h-taking-a-closer-look-at-titanium">Taking a closer look at titanium</h2>



<p>While carbon capture is an existing technology that allows for <a href="https://www.earth.com/news/trees-struggling-to-breathe-store-co2-hotter-climate/" target="_blank" rel="noreferrer noopener">CO<sub>2</sub></a> to be filtered from the air, current implementations are cost-prohibitive and energy-intensive. </p>



<p>This is precisely where the OSU team's work comes into play. The researchers decided to focus their attention on the element titanium.</p>



<p>"We opted to look into titanium as it's 100 times cheaper than vanadium, more abundant, more environmentally friendly and already well established in industrial uses," noted Bach. </p>



<p>"It also is right next to vanadium on the periodic table, so we hypothesized that the carbon capture behavior could be similar enough to vanadium to be effective."</p>



<h2 class="wp-block-heading" id="h-carbon-capture-capacity-of-titanium">Carbon capture capacity of titanium</h2>



<p>In the course of their research, the team synthesized several new tetraperoxo titanate structures - compounds containing a titanium atom associated with four peroxide groups. These new compounds showed varying degrees of effectiveness in capturing CO<sub>2</sub>.</p>



<p>"Our favorite carbon capture structure we discovered is potassium tetraperoxo titanate, which is extra unique because it turns out it is also a peroxosolvate," said Bach. </p>



<p>"That means that in addition to having the peroxide bonds to titanium, it also has hydrogen peroxide in the structure, which is what we believe makes it so reactive."</p>



<p>The research indicates that the carbon capture capacity of potassium tetraperoxo titanate is roughly double that of vanadium peroxide - a result which gives the team significant grounds for optimism.</p>



<p>"Titanium is a cheaper, safer material with a significantly higher capacity," said Bach.</p>



<h2 class="wp-block-heading" id="h-the-ongoing-fight-against-climate-change">The ongoing fight against climate change</h2>



<p>While the fight against <a href="https://www.earth.com/news/climate-change-earth-energy-imbalance-temperature-rise/" target="_blank" rel="noreferrer noopener">climate change</a> is ongoing, this research sheds new light on the potential of using an abundant and cost-effective element like titanium to capture CO<sub>2</sub> directly from the air.</p>



<p>The study highlights the critical importance of interdisciplinary collaboration and cutting-edge science for addressing the complexities of climate challenges.</p>



<p>By focusing on scalable and affordable solutions, such advances bring us closer to a future where technological innovation can help restore the balance of our atmosphere.</p>



<p>It is yet another reminder that, with innovative thinking, steadfast commitment, and a good dose of scientific curiosity, we can make strides towards a more <a href="https://www.earth.com/news/nature-inspires-solutions-for-a-sustainable-future/" target="_blank" rel="noreferrer noopener">sustainable future</a>.</p>



<p>The <a href="https://oregonstate.edu/" target="_blank" rel="noreferrer noopener">OSU</a> team included Professor Tim Zuehlsdorff, Professor Konstantinos Goulas, postdoctoral researcher Eduard Garrido Ribó, and crystallographer Lev Zakharov. The team also included graduate students Jacob Hirschi, Zhiwei Mao and Makenzie Nord.</p>



<p>Details of the research are found in this <a href="https://news.oregonstate.edu/news/new-chemical-structures-developed-oregon-state-show-vastly-improved-carbon-capture-ability">press release</a> from OSU.</p>

Titanium is a promising and abundant resource for carbon capture

Titanium has emerged as a key player in a recent...

<p>Astronomers have uncovered a mysterious phenomenon involving a jet from a supermassive black hole that collided with an unidentified object in its path.</p>



<p>This discovery, made using NASA's Chandra X-ray Observatory, comes from observations of the galaxy Centaurus A (Cen A), which is located about 12 million light-years from Earth. </p>



<p>The findings offer a fascinating glimpse into the powerful interactions that happen around black holes.</p>



<h2 class="wp-block-heading" id="h-centaurus-a-and-its-black-hole">Centaurus A and its black hole</h2>



<p>Centaurus A has long been the subject of intrigue for astronomers due to supermassive <a href="https://www.earth.com/news/rare-gamma-ray-flare-unleashed-from-a-supermassive-black-hole/" target="_blank" rel="noreferrer noopener">black hole</a> at its center. This black hole produces jets of high-energy particles, which extend across the galaxy. </p>



<p>The jets are not emitted from within the black hole itself but are generated by the intense gravitational and magnetic fields that surround it.</p>



<p>In a composite image of Cen A, <a href="https://www.nasa.gov/mission/chandra-x-ray-observatory/" target="_blank" rel="noreferrer noopener">Chandra</a>'s data reveals different X-ray energy levels. Low-energy X-rays appear in pink, medium-energy in purple, and high-energy in blue. </p>



<p>This visual distinction helps researchers pinpoint specific phenomena within the galaxy.</p>



<h2 class="wp-block-heading" id="h-understanding-black-hole-jets-the-basics">Understanding black hole jets -- the basics</h2>



<p>Black hole jets are some of the universe’s most spectacular and <a href="https://www.earth.com/news/black-hole-jets-m87-cause-stars-to-erupt-as-they-pass-through-galaxies/" target="_blank" rel="noreferrer noopener">powerful phenomena</a>. When matter spirals into a black hole, it forms a swirling disk called an accretion disk around the black hole. </p>



<p>As the material in this disk gets hotter and moves faster, it generates intense magnetic fields. These magnetic fields can channel some of the infalling matter away from the black hole, <a href="https://www.earth.com/news/black-hole-jets-are-like-million-light-year-long-jedi-lightsabers/" target="_blank" rel="noreferrer noopener">shooting it out into space</a> at nearly the speed of light in narrow, focused beams. </p>



<p>These jets can stretch for thousands or even <a href="https://www.earth.com/news/porphyrion-largest-black-hole-jets-ever-seen-is-23-million-light-years-long/" target="_blank" rel="noreferrer noopener">millions of light-years</a>, lighting up galaxies and influencing their surroundings in incredible ways.</p>



<p>What makes black hole jets so fascinating is their impact on the cosmos. These jets can blow away gas and dust from their host galaxies, regulating star formation and shaping the galaxy’s evolution. </p>



<p>They also play a key role in distributing energy and heavy elements across the universe, which can influence the formation of new stars and planets.</p>



<h2 class="wp-block-heading" id="h-mystery-of-an-unusual-x-ray-feature">Mystery of an unusual X-ray feature</h2>



<p>The highlight of this study is an unusual X-ray feature called C4. This source appears near the jet’s path and exhibits a distinct V-shaped emission that is connected to a bright X-ray source.</p>



<p>The arms of the "V" stretch at least 700 light-years long, emphasizing the scale of this <a href="https://www.earth.com/news/hubble-took-the-closest-ever-image-of-a-quasar-and-captured-some-weird-things/" target="_blank" rel="noreferrer noopener">cosmic event</a>. For comparison, the nearest star to Earth is only about 4 light-years away.</p>



<p>Astronomers believe the X-rays from C4 result from the jet’s particles colliding with gas from stellar wind. This collision generated turbulence, which increased gas density in the jet and sparked the observed X-ray emission.</p>



<p>However, the exact identity of the object that caused this interaction remains elusive.</p>



<h2 class="wp-block-heading" id="h-black-hole-jet-collision">Black hole jet collision</h2>



<p>While Cen A hosts other examples of jet <a href="https://www.earth.com/news/hubble-spots-two-supermassive-black-holes-spiraling-on-collision-course/" target="_blank" rel="noreferrer noopener">interactions</a> with objects -- such as massive stars or gas clouds -- C4 stands apart. Unlike the elliptical blobs seen in previous cases, C4’s V-shape is unique.</p>



<p>"This is not the first time astronomers have seen a black hole jet running into other objects in Cen A. However, C4 stands out from these by having the V-shape in X-rays," explained David Bogensberger, lead author of the study.</p>



<p>The differing post-collision appearances could be linked to the nature of the object struck by the jet or the angle of the impact. </p>



<p>The bottom arm of the "V" aligns roughly with the jet’s path, supporting the idea of turbulence. The top arm, however, poses more questions due to its large angle relative to the jet.</p>



<h2 class="wp-block-heading" id="h-enigmatic-behavior-of-black-holes">Enigmatic behavior of black holes</h2>



<p>Chandra’s unique X-ray capabilities make it the only observatory capable of capturing such features in the distant cosmos. </p>



<p>Researchers aim to decipher why C4’s interaction diverges from others in Cen A. This may unlock insights into how jets behave when encountering different types of obstacles.</p>



<p>The study has been detailed in a recent issue of <em>The Astrophysical Journal</em>, authored by David Bogensberger and a team of international researchers. </p>



<p>The findings contribute to the broader understanding of black hole jets and their dynamic <a href="https://www.earth.com/news/black-holes-capture-magnetic-fields-from-collapsing-stars/" target="_blank" rel="noreferrer noopener">interactions with the cosmos</a>.</p>



<p>As astronomers continue to study these celestial phenomena, mysteries like C4 remind us of the complexity and wonder of the universe. </p>



<p>Each discovery brings us closer to understanding the enigmatic behavior of black holes and their far-reaching influence.</p>



<h2 class="wp-block-heading" id="h-centaurus-a-and-galaxy-mergers">Centaurus A and galaxy mergers</h2>



<p>Centaurus A is one of the brightest radio sources in the sky, making it a key target for astronomers who are studying active galaxies.</p>



<p>Its distinct appearance, featuring a warped dust lane and a surrounding halo of stars, suggests it underwent a collision with another <a href="https://www.earth.com/news/black-holes-captured-redirecting-jets-beams-like-death-star-weapon/" target="_blank" rel="noreferrer noopener">galaxy</a> in the past. </p>



<p>This galactic merger may have contributed to its active central black hole and the formation of its spectacular jets.</p>



<p>Additionally, Cen A is known for its high star formation rate, particularly in regions affected by jets. </p>



<p>These jets compress surrounding gas, triggering the birth of new stars. The jets’ influence on gas density plays a key role in the formation of new stars.</p>



<p>The way the black hole's energy affects the surrounding environment can help astronomers understand the broader processes of galaxy formation and growth over time. It provides insight into how <a href="https://www.earth.com/news/awakening-of-a-black-hole-witnessed-for-the-first-time/" target="_blank" rel="noreferrer noopener">galaxy</a> mergers and black hole activity shape the evolution of galaxies.</p>

Enormous jet from a supermassive black hole crashes into an unidentified object

Astronomers have uncovered a mysterious phenomenon involving a jet from...

<p>Could the decades-long mystery of unusual star movements in Omega Centauri, the largest star cluster in the Milky Way, finally be solved?</p>



<p>Located in the constellation Centaurus, Omega Centauri is a massive cluster containing nearly ten million stars. Astronomers have long puzzled over the unexpected high velocities of stars near its center. </p>



<p>The debate centers on whether these movements are caused by an “<a href="https://www.earth.com/news/intermediate-mass-black-holes-survive-and-thrive-in-giant-star-clusters/" target="_blank" rel="noreferrer noopener">intermediate-mass black hole</a>” (IMBH), weighing around 100,000 times the mass of the Sun, or a cluster of smaller “stellar-mass” black holes, each just a few times the Sun's mass.</p>



<h2 class="wp-block-heading" id="h-a-cluster-or-a-singular-giant">A cluster or a singular giant?</h2>



<p>Astronomers have theorized that Omega Centauri’s center might host a cluster of black holes, naturally forming through stellar evolution. </p>



<p>However, experts also speculated that most of these black holes would have been ejected over time due to gravitational interactions with other stars, which made the presence of a single intermediate-mass black hole more plausible.</p>



<p>The case for an IMBH gained further strength when new evidence suggested that certain fast-moving stars near the cluster's center could only achieve such speeds through interactions with a massive <a href="https://www.earth.com/news/high-speed-stars-reveal-hidden-black-hole-in-omega-centauri/" target="_blank" rel="noreferrer noopener">black hole</a>.</p>



<h2 class="wp-block-heading" id="h-formation-of-supermassive-black-holes">Formation of supermassive black holes</h2>



<p>IMBHs are particularly intriguing to astronomers as they might represent a missing link between stellar-mass black holes and supermassive black holes.&nbsp;</p>



<p>Stellar-mass black holes form when massive stars collapse, while supermassive black holes - millions to billions of times the Sun's mass - dominate the centers of large galaxies. </p>



<p>Understanding how <a href="https://www.earth.com/news/how-do-black-holes-become-supermassive/" target="_blank" rel="noreferrer noopener">supermassive black holes</a> form - possibly starting as IMBHs - remains one of astronomy's greatest mysteries.</p>



<h2 class="wp-block-heading" id="h-star-velocities-in-omega-centauri">Star velocities in Omega Centauri</h2>



<p>In a fresh approach to this enigma, researchers from the <a href="https://www.surrey.ac.uk/">University of Surrey</a>, the <a href="https://www.iac.es/" target="_blank" rel="noreferrer noopener">Instituto de Astrofísica de Canarias</a> (IAC, Spain), and the Annecy-le-Vieux Laboratoire de Physique Théorique (France) examined the anomalous star velocities in Omega Centauri using a new type of data: pulsar accelerations.</p>



<p><a href="https://www.earth.com/news/pulsars-are-helping-astronomers-pinpoint-dark-matter/" target="_blank" rel="noreferrer noopener">Pulsars</a> are remnants of dying stars, typically weighing up to twice the Sun’s mass but only about 20 kilometers in diameter. Spinning up to 700 times per second, they emit radio waves in a lighthouse-like pattern that sweeps past Earth.&nbsp;</p>



<p>Acting as natural, highly precise clocks, pulsars allow scientists to measure their accelerations and, in turn, the gravitational forces acting on them.</p>



<p>For the first time, the team combined pulsar acceleration measurements with data on star velocities. This innovative approach enabled them to probe the gravitational field at the cluster’s center and differentiate between the effects of an IMBH and a cluster of stellar-mass black holes.&nbsp;</p>



<p>The results leaned toward the latter explanation: a cluster of smaller black holes rather than a single IMBH.</p>



<h2 class="wp-block-heading" id="h-the-hunt-for-intermediate-mass-black-holes">The hunt for intermediate-mass black holes </h2>



<p>“The hunt for elusive intermediate-mass black holes continues. There could still be one at the center of Omega Centauri, but our work suggests that it must be less than about six thousand times the mass of the Sun and live alongside a cluster of stellar-mass black holes,” noted study co-author Justin Read, an astronomer at the University of Surrey. </p>



<p>“There is, however, every chance of us finding one soon. More and more pulsar accelerations are coming, allowing us to peer into the centers of dense star clusters and hunt for black holes more precisely than ever before.”</p>



<h2 class="wp-block-heading" id="h-significance-of-studying-omega-centauri">Significance of studying Omega Centauri </h2>



<p>Study lead author Andrés Bañares Hernández, an astronomer at IAC, noted that we have long known about supermassive black holes at galaxy centers and smaller stellar-mass black holes within our own galaxy.&nbsp;</p>



<p>“However, the idea of intermediate-mass black holes, which could bridge the gap between these extremes, remains unproven,” said Hernández.</p>



<p>“By studying Omega Centauri - a remnant of a dwarf galaxy - we have been able to refine our methods and take a step forward in understanding whether such black holes exist and what role they might play in the evolution of star clusters and galaxies." </p>



<p>"This work helps resolve a two-decade-long debate and opens new doors for future exploration.”</p>



<h2 class="wp-block-heading" id="h-pulsars-a-key-to-further-discoveries">Pulsars: A key to further discoveries</h2>



<p>The researchers also highlighted Omega Centauri as a prime environment for studying the formation and behavior of pulsars, given the cluster’s density and gravitational complexity.&nbsp;</p>



<p>The recent discovery of numerous pulsars within Omega Centauri has provided new opportunities to investigate their origins.</p>



<p>“The formation of pulsars is also an active field of study because a large number of them have recently been detected. Omega Centauri is an ideal environment to study models of their formation, which we have been able to do for the first time in our analysis," Hernández noted.</p>



<p>While the mystery of an IMBH in Omega Centauri remains unresolved, this study represents a significant step forward.&nbsp;</p>



<p>The new data and techniques for analyzing gravitational fields and pulsar accelerations could soon reveal whether intermediate-mass black holes exist and, if so, what role they play in the <a href="https://www.earth.com/news/webb-telescope-confirms-hubble-constant-our-understanding-of-universe-expansion-very-wrong/" target="_blank" rel="noreferrer noopener">universe</a>’s cosmic architecture.</p>

Mysterious star movement in Omega Centauri may finally be explained

Could the decades-long mystery of unusual star movements in Omega...

Humpback,Whale,Breaching.,Humpback,Whale,Jumping,Out,Of,The,Water.

<p>Humpback whales have long impressed us with their incredible travel distances, often covering thousands of miles between feeding and breeding areas. </p>



<p>Scientists recently recorded an adult male humpback whale making an unexpected journey from South America to Africa, traveling more than 8,106 miles (13,046 kilometers). </p>



<p>This new finding suggests there is still much to learn about how whales spread across oceans, especially in the Southern Hemisphere.</p>



<p>“These animals are distinct individuals, and they’ll do surprising things. These oceans are very much connected spaces, and whales travel beyond borders," enthused Ted Cheeseman, a marine biologist at <a href="https://www.scu.edu.au/" target="_blank" rel="noreferrer noopener">Southern Cross University</a>.</p>



<h2 class="wp-block-heading" id="h-record-breaking-journey">Record-breaking journey</h2>



<p>A new study detailed this whale’s journey as the longest migration ever recorded for <a href="https://www.earth.com/news/ai-helps-humans-have-20-minute-conversation-with-humpback-whale-named-twain/" target="_blank" rel="noreferrer noopener">a single whale</a>. The trek also marked the first time researchers documented an adult male humpback traveling between the Pacific and Indian oceans. </p>



<p>The whale was first spotted off the coast of Colombia in 2013 and seen again near that area a few years later. But in 2022, it turned up near Zanzibar, off the coast of East Africa. </p>



<p>Researchers noted that the typical migration route can exceed 4,971 miles (8,000 kilometers) one way, and this whale’s path was close to twice that distance, according to the study published in the journal <em>Royal Society Open Science</em>.</p>



<h2 class="wp-block-heading" id="h-humpback-whale-travel-behavior">Humpback whale travel behavior</h2>



<p>Scientists say this unexpected movement sheds light on how adaptable humpbacks can be. They say that global data are needed to better <a href="https://www.earth.com/news/how-a-warming-climate-will-change-the-humpback-whales-diet/" target="_blank" rel="noreferrer noopener">understand whale behavior</a>. </p>



<p>Such large-scale research could show how whales respond to environmental changes and whether factors like shifting ocean temperatures or reduced food availability push them to seek new territories. </p>



<p>The whale’s travel between distinct breeding grounds highlights that humpbacks, while often returning to the same places, are not completely predictable. </p>



<p>“Our dogmatic thinking is that (whales) always go to the place where they came from,” said Ari Friedlaender, professor of ocean sciences at the <a href="https://www.ucsc.edu/" target="_blank" rel="noreferrer noopener">University of California, Santa Cruz</a>, who was not involved in the study. </p>



<p>“But there has to be some movement where you get some (animal) explorers that decide, for whatever reason, to follow a different path," Friedlaender told CNN.</p>



<h2 class="wp-block-heading" id="h-tracking-a-unique-individual">Tracking a unique individual</h2>



<p>Humpbacks exist in <a href="https://www.earth.com/news/humpback-whales-have-moved-their-singing-rituals-away-from-shorelines/" target="_blank" rel="noreferrer noopener">oceans all over the world</a> and are known for covering huge distances. This whale’s journey stands out because it involved switching between two separate breeding areas. </p>



<p>Males often travel widely when competing for mates, and scientists note that these movements may depend on shifting conditions. </p>

<p>They tracked the whale using a platform called <a href="https://happywhale.com/home" target="_blank" rel="noreferrer noopener">Happy Whale</a>, which Cheeseman cofounded. It lets citizen scientists, researchers, and whale watchers share their whale photos, helping experts identify whales by the unique underside of their tails. </p>



<p>“When (whales) dive, they lift their tails, and anyone taking a picture of their tail can record the identity of the animal,” Cheeseman said.</p>



<h2 class="wp-block-heading" id="h-changing-patterns-in-a-changing-world">Changing patterns in a changing world</h2>



<p>Humpbacks generally show strong loyalty to their breeding sites, though occasional shifts happen. </p>



<p>Researchers do not fully understand why whales change their breeding locations, but they see that males and females can both move between different spots. </p>



<p>Scientists think that environmental conditions, competition, and mate availability may influence these changes. Instead of repeating their old routes, some whales may strike out in new directions. </p>



<p>Cheeseman explained that the whale in this study may have left Colombia due to competition with other males for mates or because of food scarcity, noting that these conditions might push whales to <a href="https://www.earth.com/news/humpback-whales-perform-full-body-scrubs-on-their-return-south/" target="_blank" rel="noreferrer noopener">explore new waters</a>.</p>



<h2 class="wp-block-heading" id="h-why-does-this-matter">Why does this matter?</h2>



<p>In the 20th century, whaling in the Indian Ocean killed nearly 95% to 99% of the humpback population there, according to Cheeseman. </p>



<p>That leaves many questions unanswered about their current habits. Researchers say that understanding <a href="https://www.earth.com/news/add-humpback-whales-to-list-of-animals-that-build-and-use-tools/" target="_blank" rel="noreferrer noopener">modern humpback behavior</a> is like observing a classroom full of youngsters without many older individuals around. </p>



<p>“We’re looking at their behavior like going into a kindergarten classroom,” Cheeseman said. “There’s maybe one adult, someone who’s middle-aged and a whole bunch of children.” </p>



<p>These shifting demographics mean whales are making new cultural patterns, and unexpected movements could shape how these creatures interact with each other.</p>



<h2 class="wp-block-heading" id="h-documenting-humpback-whale-travel">Documenting humpback whale travel</h2>



<p>Since the 1970s, whale watchers and scientists have used tail photography to identify individuals. Platforms like Happy Whale now let many people submit images, broadening the amount of information available. </p>



<p>Cheeseman noted that the database currently includes around 109,000 individual whales. The increased collaboration encourages more inclusive <a href="https://www.earth.com/news/humpback-whales-fail-to-respond-to-vessel-noise/" target="_blank" rel="noreferrer noopener">research projects worldwide</a>. </p>



<p>“(Happy Whale) is going to bring more opportunity for sharing and networking to make our global research partnerships more inclusive,” Friedlaender said.</p>



<h2 class="wp-block-heading" id="h-uncertain-futures-and-new-connections">Uncertain futures and new connections</h2>



<p>This whale’s travel outside its usual breeding pattern raises questions about acceptance in its new location. Changes in travel routes may mean whales encounter different populations. </p>



<p>As these movements occur, whales could begin mixing genes and behaviors, influencing how future generations migrate and <a href="https://www.earth.com/news/humpback-whales-felt-less-stressed-during-the-pandemic/" target="_blank" rel="noreferrer noopener">choose their homes</a>. </p>



<p>Cheeseman said that new sightings will provide more clues. “With every photograph we receive we’re looking for every whale we know,” Cheeseman said.</p>



<h2 class="wp-block-heading" id="h-humpback-whale-travel-creates-communities">Humpback whale travel creates communities</h2>



<p>The Indian Ocean now holds younger populations of humpbacks trying to find their way. Some may follow old patterns, while others search for new possibilities. </p>



<p>In addition, shifts in migration might change social bonds and behaviors.</p>



<p>“These different paths can connect populations that we otherwise would never think would be in touch with each other to share information and genes that make these populations into more of a global community," Friedlaender concluded.</p>



<p>No one can say when or where this whale will appear next, but future sightings and photographs may deepen our understanding. The world’s oceans hold many secrets about how humpbacks live, move, and interact. </p>



<p>As more data come to light, researchers and regular folks can pool their knowledge, helping piece together how whales adapt to changing waters and shifting relationships.</p>

Humpback whale travels farther than any mammal ever recorded

Humpback whales have long impressed us with their incredible travel...

<p>Have you ever wondered how our brain stores memories? For two decades, it has been acknowledged that electrical waves in our brains during deep sleep have a crucial role in memory formation. However, the details of this process have remained a mystery. </p>



<p>Following an extensive study, a team of researchers from <a href="https://www.charite.de/en/" target="_blank" rel="noreferrer noopener">Charité - Universitätsmedizin Berlin</a> has proposed a compelling explanation.</p>



<h2 class="wp-block-heading" id="h-deep-sleep-and-memory-formation">Deep sleep and memory formation </h2>



<p>How do memories become permanent? Most experts agree that while we are immersed in the land of dreams, our brains have a quick recap of the day's happenings. Here's how it works.</p>



<p>The short-term memory info in the hippocampus is transferred to the long-term memory in the neocortex. </p>



<p>The unsung heroes of this operation are "slow waves." These are slow, synchronous oscillations of electrical voltage in the cortex that occur during our deepest sleep phase.</p>



<p>"We’ve known for many years that these slow waves contribute to the formation of memory. When slow-wave sleep is artificially augmented from outside, memory improves," explained Professor Jörg Geiger.</p>



<p>But there's been a lingering question - what exactly is happening inside our heads when this process occurs?</p>



<h2 class="wp-block-heading" id="h-slow-waves-and-brain-connectivity">Slow waves and brain connectivity </h2>



<p>"Synaptic mechanisms that contribute to human <a href="https://www.earth.com/news/how-does-our-brain-form-long-term-memories/" target="_blank" rel="noreferrer noopener">memory consolidation</a> remain largely unexplored. Consolidation critically relies on sleep," noted the researchers.</p>



<p>"During slow wave sleep, neurons exhibit characteristic membrane potential oscillations known as UP and DOWN states. Coupling of memory reactivation to these slow oscillations promotes consolidation, though the underlying mechanisms remain elusive."</p>



<p>To put it simply, these slow electrical waves influence the strength of synaptic connections between the neurons in the neocortex, and thus their receptivity.</p>



<h2 class="wp-block-heading" id="h-mysterious-mechanisms-of-memory-formation">Mysterious mechanisms of memory formation </h2>



<p>With the use of unique, intact human brain tissue, the team has been able to uncover some of the processes that are linked to memory formation during <a href="https://www.earth.com/news/deep-sleep-improves-memory-formation-and-recall/" target="_blank" rel="noreferrer noopener">deep sleep</a>.</p>



<p>The study was focused on tissue samples from 45 patients who had undergone treatment for epilepsy or a <a href="https://www.earth.com/news/how-antidepressants-could-help-treat-brain-tumors/" target="_blank" rel="noreferrer noopener">brain tumor</a> at Charité, the Evangelisches Klinikum Bethel (EvKB) hospital, or the University Medical Center Hamburg-Eppendorf (UKE).</p>



<p>The experts managed to simulate the voltage fluctuations of slow waves during deep sleep in this tissue, then gauged the response of the nerve cells.</p>



<h2 class="wp-block-heading" id="h-the-timing-of-long-term-memory-storage">The timing of long-term memory storage</h2>



<p>The researchers discovered that synaptic connections between neurons in the neocortex peak at a very specific moment during the voltage fluctuations. They found that the synapses function most efficiently right after the voltage swings from low to high.</p>



<p>"During that brief time window, the cortex can be thought of as having been placed in a state of elevated readiness. If the brain plays back a memory at exactly this time, it is transferred to long-term memory especially effectively,” explained Franz Xaver Mittermaier, lead author of the study.</p>



<p>Worldwide, research groups are exploring ways to use electrical impulses or auditory signals to influence slow waves during sleep. Current stimulation approaches are optimized through the trial-and-error method, which is time-consuming and laborious.</p>



<p>This new understanding of the "perfect timing" could aid in devising methods to boost memory formation more efficiently.</p>



<h2 class="wp-block-heading" id="h-enhancing-memory-through-sleep">Enhancing memory through sleep</h2>



<p>The insights from this study open the door to new applications for memory enhancement. By understanding the exact timing when synaptic connections are most effective, researchers can refine techniques to influence slow-wave activity.</p>



<p>This could revolutionize treatments for memory-related conditions, such as <a href="https://www.earth.com/news/how-why-some-brains-resist-alzheimers-disease-symptoms/" target="_blank" rel="noreferrer noopener">Alzheimer’s disease</a> or age-related cognitive decline.</p>



<p>Beyond clinical applications, optimizing memory during sleep could benefit learning and performance, offering new possibilities for education and skill acquisition.</p>



<h2 class="wp-block-heading" id="h-broader-applications-of-the-findings">Broader applications of the findings</h2>



<p>The findings of this research extend beyond memory formation and cognitive impairment. By deepening our understanding of how the brain operates during <a href="https://www.earth.com/news/sleep-is-essential-for-memory-formation/" target="_blank" rel="noreferrer noopener">sleep</a>, scientists can explore innovative applications in various fields.</p>



<p>For instance, optimizing sleep-related brain activity could aid in treating sleep disorders or managing stress-related conditions. </p>



<p>Additionally, this knowledge might inspire advances in technology, such as brain-computer interfaces designed to enhance cognitive performance. The findings may even lead to memory retention training programs that are tailored to individual sleep patterns.</p>



<p>Ultimately, the potential to harness the power of deep sleep could transform how we approach mental health and neurological well-being.</p>

Experts pinpoint the exact timing of memory formation during sleep

Have you ever wondered how our brain stores memories? For...

<p>Deep meditative states are often described as “pure consciousness experiences,” where individuals feel alert but do not perceive anything other than “awareness itself.” These states of meditation are frequently characterized as "timeless," with no sense of past, future, or any other temporal features. </p>



<p>Yet, a paradox emerges: if one is consciously aware and alert, wouldn’t one also be aware of the passage of time? Can these profound meditative states genuinely be devoid of any temporal dimension?</p>



<h2 class="wp-block-heading" id="h-understanding-timeless-meditation">Understanding timeless meditation</h2>



<p>In an article published in <a href="https://dx.doi.org/10.1093/pq/pqae081" target="_blank" rel="noreferrer noopener"><em>The Philosophical Quarterly</em></a>, Professor Akiko Frischhut from <a href="https://www.sophia.ac.jp/eng/" target="_blank" rel="noreferrer noopener">Sophia University</a> in Japan examines this intriguing contradiction.</p>



<p>“My paper aims to give a coherent conceptualization of deep meditative states, focusing in particular on phenomenal temporality during meditation,” she explained. </p>



<p>“The central question is whether it is possible to have an experience that is completely timeless, without any temporal feature whatsoever.”</p>



<p>Thomas Metzinger, a prominent philosopher, has argued that first-person accounts of deep meditation from diverse cultures and eras consistently describe these states in strikingly similar terms. </p>



<p>A common theme is that such states of meditation feel both “completely timeless” and “continuously ongoing.”</p>



<p>However, if something is described as “ongoing,” it implies the presence of duration, meaning that it cannot be entirely timeless. </p>



<p>This contradiction forms the basis of Frischhut’s investigation. She argues that deep <a href="https://www.earth.com/news/mindfulness-meditation-is-a-powerful-weapon-against-chronic-pain/" target="_blank" rel="noreferrer noopener">meditative states</a> must inherently involve at least one minimal temporal quality: duration.</p>



<h2 class="wp-block-heading" id="h-timeless-meditation-no-beginning-or-end">Timeless meditation: No beginning or end</h2>



<p>To resolve this paradox, Frischhut introduces the “Extended Now Interpretation (ENI).” This concept identifies a critical ambiguity in the term “timeless.”&nbsp;</p>



<p>While some use the word to mean entirely devoid of any temporal features, others apply it to describe a state with an indeterminate duration that lacks specific temporal structures such as change, order, succession, beginning, or end.&nbsp;</p>



<p>Meditators may describe their experience as “timeless” because they perceive no temporal structure, even though they experience a sense of ongoing duration.</p>



<p>Frischhut’s argument suggests that deep meditative states occur within what can be described as an extended present. </p>



<p>During these states, meditators perceive no change or progression of moments, yet they are immersed in an experience with duration. </p>



<p>According to the ENI, “timelessness” refers not to the absence of <a href="https://www.earth.com/news/nature-experiences-alter-time-perception/" target="_blank" rel="noreferrer noopener">time</a> entirely but rather to the absence of any discernible temporal framework within the experienced duration.</p>



<h2 class="wp-block-heading" id="h-alertness-in-deep-meditative-states">Alertness in deep meditative states</h2>



<p>Frischhut delves deeper into the role of sustained <a href="https://www.earth.com/news/bright-light-instantly-enhances-brain-function-alertness/" target="_blank" rel="noreferrer noopener">alertness</a> in providing meditators with an implicit awareness of duration, even in the absence of explicit temporal markers.&nbsp;</p>



<p>This form of alertness, found in deep meditative states, can be thought of as a poised state of attention. Over time, meditators either maintain this alert state or slip into less attentive conditions.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/12/meditation_awareness_time-perception_graphic_credit-Sophia-University_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/12/meditation_awareness_time-perception_graphic_credit-Sophia-University_1s.webp" alt="In this study, a researcher from Sophia University presents an in-depth analysis of how and why deep meditative states are often described as &quot;atemporal&quot; or &quot;timeless.&quot; Credit: Akiko Frischhut from Sophia University, Japan" class="wp-image-1953771"/></a><figcaption class="wp-element-caption"><em>In this study, a researcher from Sophia University presents an in-depth analysis of how and why deep meditative states are often described as "atemporal" or "timeless." Credit: Akiko Frischhut from Sophia University, Japan</em></figcaption></figure>



<p>The choice to remain alert -- or the potential to lose alertness -- provides a subtle sense of time’s passage, Frischhut argues. This awareness does not require meditators to consciously track successive moments. </p>



<p>Instead, the very act of maintaining attention creates an awareness of duration, even without recognizing the progression of one moment to the next.</p>



<h2 class="wp-block-heading" id="h-addressing-the-lack-of-memory">Addressing the lack of memory</h2>



<p>A significant challenge to Frischhut’s argument lies in the fact that meditators often report an absence of memory during these deep states.&nbsp;</p>



<p>Without <a href="https://www.earth.com/news/sleep-is-essential-for-memory-formation/">memory</a>, how can one perceive any sense of time? To address this, Frischhut posits that the experience of alertness itself carries a unique phenomenological quality that distinguishes it from a lack of alertness.</p>



<p>She draws an analogy to hearing two consecutive knocks on a door: the second knock feels different because it follows the first. </p>



<p>Similarly, even without conscious memory, the flow of alertness from one moment to the next provides meditators with an implicit awareness of duration. </p>



<p>This seamless continuity of momentary alertness allows meditators to experience a sense of ongoing presence, even without actively recalling or recognizing previous moments.</p>



<h2 class="wp-block-heading" id="h-this-is-cool-but-why-does-it-matter">This is cool, but why does it matter?</h2>



<p>This analysis sheds new light on the nature of deep meditative states and helps clarify reports that have emerged consistently throughout human history.&nbsp;</p>



<p>Frischhut, whose academic focus includes unusual states of consciousness, hopes her findings will spark further discussion in this relatively underexplored area.</p>



<p>“In my opinion, non-ordinary states of <a href="https://www.earth.com/news/consciousness-may-stem-from-unseen-dimensions-beyond-our-reality/" target="_blank" rel="noreferrer noopener">consciousness</a> such as deep meditative states, dreams, and psychedelic states have not been sufficiently investigated in contemporary philosophy,” Frischhut said.</p>



<p>She emphasizes that exploring how time is perceived in these altered states could offer profound insights into human cognition and the workings of the mind.&nbsp;</p>



<p>By examining the subtle dynamics of phenomenal temporality, Frischhut’s work paves the way for a deeper understanding of how we experience time across both ordinary and extraordinary states of consciousness.</p>

No past, no future: Why deep meditation experiences feel 'timeless'

Deep meditative states are often described as “pure consciousness experiences,”...

<p>Concerns about TikTok’s influence on youth are common, but a new study led by Emilie Owens provides a more nuanced view.&nbsp;</p>



<p>Published in the journal <a href="https://dx.doi.org/10.3366/ircl.2024.0562" target="_blank" rel="noreferrer noopener"><em>International Research in Children's Literature</em></a>, the study explores how TikTok shapes teenagers' lives and behaviors, offering insights that challenge the platform’s negative reputation.</p>



<h2 class="wp-block-heading" id="h-teenagers-and-their-phones">Teenagers and their phones</h2>



<p>Owens, a doctoral student in media studies at the <a href="https://www.uio.no/english/" target="_blank" rel="noreferrer noopener">University of Oslo</a>, set out to better understand the relationship between teenagers and their phones. “My goal has been to get to know teenagers and their phones. I wanted to be in the room with them,” she explained.&nbsp;</p>



<p>Her curiosity was driven by the often critical attitudes adults hold toward TikTok.&nbsp;</p>



<p>While acknowledging its commercial downsides, Owens emphasizes the positive role the platform can play for teens. “<a href="https://www.earth.com/news/internet-addiction-impairs-brain-function-in-teenagers/" target="_blank" rel="noreferrer noopener">Teenagers</a> in my research say that TikTok makes them happy and provides comfort. They also see it as a social activity.”</p>



<h2 class="wp-block-heading" id="h-exploring-teenagers-use-of-tiktok">Exploring teenagers’ use of TikTok</h2>



<p>Over seven months, Owens conducted her study in an international high school in Oslo.&nbsp;</p>



<p>To capture authentic teenage behavior, she encouraged students to interact with TikTok as they normally would, occasionally assigning tasks such as finding or creating content.&nbsp;</p>



<p>By observing them in action, she gained a deeper understanding of their relationship with the platform.</p>



<p>Owens initially expected significant gender differences in TikTok use, but her findings painted a more complex picture.&nbsp;</p>



<p>While a small group of boys gravitated toward sarcastic, political, and controversial content, the majority of students - regardless of gender - focused on humorous memes, quirky videos, and educational material.</p>



<h2 class="wp-block-heading" id="h-teenagers-learning-through-tiktok">Teenagers learning through TikTok</h2>



<p>One surprising outcome of the study was how much teenagers claimed to learn from TikTok. A 16-year-old girl noted that TikTok often provided clear explanations of current events or academic topics.&nbsp;</p>



<p>“All of these controversies going on? There's always someone explaining it there. Or I have actually seen Russian ladies, like, describe math to me, and I understand it,” she said.&nbsp;</p>



<p>Similarly, a 17-year-old boy praised the platform’s short videos for getting “straight to the point without any explanation,” which he found particularly effective.</p>



<p>TikTok, Owens observed, often acts as a lens through which teenagers view the world. They use it in various contexts, from passing time while waiting for the bus to engaging socially by sharing videos with friends.&nbsp;</p>



<p>“In such cases, TikTok becomes a social focal point, a kind of lens through which they can see the world together,” Owens explained.&nbsp;</p>



<p>This shared experience can bridge cultural divides, particularly in international classrooms where students come from different backgrounds.</p>



<h2 class="wp-block-heading" id="h-balancing-the-good-and-the-bad">Balancing the good and the bad</h2>



<p>Despite TikTok’s positive aspects, teenagers are aware of its potential downsides. Some prefer YouTube, feeling it offers more substantial educational value. Others temporarily delete TikTok to focus on schoolwork.&nbsp;</p>



<p>One teenager mentioned the physical strain of prolonged use, noting that “after twelve hours, your eyes get sore.” While this may not be literal, it reflects the platform’s potential to consume significant amounts of time.</p>



<p>The content on TikTok also elicited mixed reactions. Teenagers recognized that the type of accounts they follow could influence their mood and motivation.&nbsp;</p>



<p>As one 16-year-old boy put it:&nbsp; “If you follow a certain type of people, it can be motivating. But if you follow a certain group, it can be very demotivating as well.”&nbsp;</p>



<p>The term “brain rot” was humorously used by the teens to describe the sillier, less meaningful content, though they didn’t take this label too seriously.</p>



<h2 class="wp-block-heading" id="h-a-customized-digital-world">A customized digital world</h2>



<p>Owens reflects on what it means for today’s teenagers to grow up with TikTok. The platform offers a highly customized experience, where users can easily move on to something else if they don’t like what they see.&nbsp;</p>



<p>“It certainly gives them a more customized world. They learn to expect things to be the way they want them,” Owens noted.&nbsp;</p>



<p>While the long-term implications remain unclear, she suggests this tailored digital environment could shape their expectations and interactions in significant ways.</p>



<h2 class="wp-block-heading" id="h-complex-relationship-between-teenagers-and-tiktok-nbsp">Complex relationship between teenagers and TikTok&nbsp;</h2>



<p>For parents, Owens points to the work of University of Oslo professor Elisabeth Staksrud, who emphasizes the importance of parental involvement in teenagers’ digital lives.&nbsp;</p>



<p>Owens echoes this advice: “It’s probably wise to be realistic. Young people use <a href="https://www.earth.com/news/spending-less-time-on-social-media-improves-your-mental-health/" target="_blank" rel="noreferrer noopener">social media</a> now, and it’s an important part of their lives. Approach it as you would any other issue in a teenager’s life. Ask them what’s happening and show that you care.”</p>



<p>Owens’ study reveals a nuanced relationship between teenagers and TikTok. While the platform poses challenges, it also offers opportunities for <a href="https://www.earth.com/news/secrets-of-learning-how-the-brain-stores-new-information/" target="_blank" rel="noreferrer noopener">learning</a>, social connection, and entertainment.&nbsp;</p>



<p>By understanding this balance, parents, educators, and researchers can better navigate the evolving digital landscape and support teenagers in making the most of their online experiences.</p>

Growing up in a digital world: TikTok makes teenagers happy

Concerns about TikTok’s influence on youth are common, but a...

<p>Proper food intake is essential for pregnant humpback whales to complete their extraordinary annual migration between Hawaii and Alaska.&nbsp;</p>



<p>Researchers with the <a href="https://www.mmrphawaii.org/" target="_blank" rel="noreferrer noopener">Marine Mammal Research Program</a> (MMRP) at the <a href="https://www.himb.hawaii.edu/" target="_blank" rel="noreferrer noopener">Mānoa Hawaiʻi Institute of Marine Biology</a> (HIMB) have revealed the energetic demands and vulnerabilities of these migratory mothers-to-be.&nbsp;</p>



<p>The findings, published in <a href="https://dx.doi.org/10.1113/JP287304" target="_blank" rel="noreferrer noopener"><em>The Journal of Physiology</em></a>, show that while the initial stages of pregnancy are relatively low in energy cost, the final trimester dramatically increases the mother’s energetic needs - just when she must fast and cover great distances without feeding.</p>



<h2 class="wp-block-heading" id="h-humpback-whales-astonishing-migrations">Humpback whales’ astonishing migrations</h2>



<p><a href="https://www.earth.com/news/humpback-whales-felt-less-stressed-during-the-pandemic/" target="_blank" rel="noreferrer noopener">Humpback whales</a> feed in polar waters and then embark on <a href="https://www.earth.com/news/humpback-whale-travels-farther-than-any-mammal-ever-recorded/" target="_blank" rel="noreferrer noopener">migrations</a> reaching up to 5,000 kilometers to the tropical regions where they mate and give birth.&nbsp;</p>



<p>During pregnancy, which lasts about 10 months, these females must travel and fast, relying solely on the energy reserves built up in feeding grounds.&nbsp;</p>



<p>By examining a combination of recent and historical data, the researchers found a direct correlation between maternal size and fetal growth: larger mothers carry larger fetuses that grow at faster rates.</p>



<h2 class="wp-block-heading" id="h-energy-demands-of-pregnant-whales">Energy demands of pregnant whales</h2>



<p>These findings allowed the team to estimate the energy demands for different stages of pregnancy. The first two-thirds of the pregnancy required only minimal extra energy, accounting for just 0.01–1.08% of the mother’s energy expenditure.&nbsp;</p>



<p>The most significant strain came in the final 100 days, when energy needs soared to 98.2% of the pregnancy’s total metabolic cost.</p>



<p>“It was surprising to see how the peak of energy requirements coincided with the onset of fasting in pregnant females, ultimately highlighting how crucial those final 100 days of pregnancy are for this migratory species,” said lead author Martin van Aswegen, a PhD student at MMRP.</p>



<p>“Females that are late in the pregnancy are therefore particularly vulnerable to disruptions in energy balance, given periods of greatest energetic stress coincide with fasting and migration to sub-tropical breeding grounds.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-vulnerable-period-for-pregnant-whales">Vulnerable period for pregnant whales</h2>



<p>According to van Aswegen, the study highlights a particularly vulnerable period for pregnant humpback whales.&nbsp;</p>



<p>“This is important, because once these whales leave their high-latitude feeding grounds, they have a finite amount of energy available to invest in their offspring over a 3–5 month fasting period, with energy requirements being even higher after calf birth.”</p>



<p>Humpback whales depend on abundant feeding during summer months in high-latitude regions to gather the energy reserves necessary for migration and <a href="https://www.earth.com/news/humpback-whale-reproduction-is-linked-to-krill-abundance/" target="_blank" rel="noreferrer noopener">reproduction</a>.&nbsp;</p>



<p>The new data highlights how critical it is for these whales to have access to sufficient prey before beginning their long journeys southward to deliver calves in warmer, predator-scarce waters.</p>



<h2 class="wp-block-heading" id="h-declining-calf-production-raises-concerns">Declining calf production raises concerns</h2>



<p>Recent observations have shown a worrying trend: there has been a 75.6% decline in the number of humpback whale mothers with calves off Hawaiʻi between 2013 and 2018.&nbsp;</p>



<p>In Southeast Alaska, a recent study documented that calf production between 2015 and 2019 was about six times lower than in pre-2015 years, while midsummer calf mortality increased tenfold from 2014 to 2019.&nbsp;</p>



<p>These declines coincided with significant, extended changes in the marine food web, leading to poor feeding conditions for humpback whales.</p>



<h2 class="wp-block-heading" id="h-complex-lives-of-humpback-whales">Complex lives of humpback whales</h2>



<p>“This research underpins future studies on humpback whale energy demands,” said Lars Bejder, co-author of the study and director of MMRP.&nbsp;</p>



<p>“Our drone-collected whale health database, developed in partnership with the <a href="https://www.alaskawhalefoundation.org/" target="_blank" rel="noreferrer noopener">Alaska Whale Foundation</a>, includes over 11,000 measurements from 8,500 individual North Pacific whales. Its extensive temporal and spatial scale offers invaluable insights into the effects of large-scale climatic events on this iconic sentinel species.”&nbsp;</p>



<p>Bejder noted that sustaining such long-term, wide-scale studies is crucial for understanding these impacts within the context of natural variability in whale health.”</p>



<p>“This research underscores the value of collaboration in tackling complex questions about the lives of humpback whales,” added Jens Currie, co-author and chief scientist at <a href="https://www.pacificwhale.org/" target="_blank" rel="noreferrer noopener">Pacific Whale Foundation</a>.&nbsp;</p>



<p>“Through large-scale collaborations, we're able to gain critical insights into the challenges migratory whales face during pregnancy to better inform conservation strategies. Together, we can address large-scale ecological challenges that no single institution could achieve alone.”</p>



<h2 class="wp-block-heading" id="h-the-pressure-faced-by-pregnant-whales">The pressure faced by pregnant whales</h2>



<p>By analyzing the whales’ energy use and nutritional demands, this study sheds light on key factors influencing whale reproductive success.&nbsp;</p>



<p>Understanding the energetic pressures faced by pregnant females can guide future <a href="https://www.earth.com/news/effective-conservation-efforts-key-to-saving-biodiversity/" target="_blank" rel="noreferrer noopener">conservation</a> efforts aimed at safeguarding feeding grounds and migration routes.&nbsp;</p>



<p>In a warming ocean where prey availability and distribution are changing, such science-based insights will prove essential for ensuring that humpback whales continue to complete their life cycle and thrive for generations to come.</p>

The hidden struggles of pregnant humpback whales

Proper food intake is essential for pregnant humpback whales to...

<p>As the holiday season unfolds, shopping reaches its peak. This year, a staggering 197 million people shopped from Black Friday to Cyber Monday, and spent a record $33.6 billion on Black Friday alone. </p>



<p>Behind the shopping frenzy lies a fascinating intersection of brain activity, neuroscience, and economics, as explored by Dr. Uma Karmarkar, a leading expert in neuroeconomics.</p>



<p>Karmarkar investigated the psychological and physical factors that drive consumer behavior, offering insights into why we buy - and how we can make more intentional choices.</p>



<h2 class="wp-block-heading" id="h-brain-science-and-shopping-behavior">Brain science and shopping behavior</h2>



<p>"Neuroeconomics is a field of study that uses theories and methods from neuroscience, psychology, and economics to better understand how people make real-world decisions," said Dr. Karmarkar, an associate professor at <a href="https://ucsd.edu" target="_blank" rel="noreferrer noopener">UC San Diego</a>.</p>



<p>With a PhD in neuroscience, as well as a PhD in consumer behavior, Dr. Karmarkar bridges the gap between basic brain science and <a href="https://www.earth.com/news/happiness-influences-online-shopping-habits/" target="_blank" rel="noreferrer noopener">everyday human actions</a>, such as shopping.</p>



<p>Her journey into neuroeconomics began with studying how brain cells process information for tasks like memory and learning. She found that the decision-making process is complex and engaging.</p>



<p>"I found it very exciting that we could build models from brain to behavior on how we make choices about health or career or finances, or even shop for groceries," said Dr. Karmarkar.</p>



<h2 class="wp-block-heading" id="h-brain-processes-involved-in-shopping">Brain processes involved in shopping </h2>



<p>When shopping, our brains engage in multiple processes. The ventral striatum, a key brain region, evaluates how much we like an <a href="https://www.earth.com/news/fashion-industrys-plastic-waste-is-a-major-environmental-threat/" target="_blank" rel="noreferrer noopener">item</a>, even when we're not actively shopping. </p>



<p>If we consider making a purchase, additional brain regions help weigh the price, willingness to pay, and overall decision.</p>



<p>Interestingly, these processes remain consistent between in-person and online shopping. However, environmental factors like interacting with physical products or being surrounded by other shoppers can create subtle differences in how decisions are made.</p>



<div class="wp-block-sendtonews-playerselector">[sendtonews key="1wHE5lBtkb-4130361-12187" type="single"]</div>



<h2 class="wp-block-heading" id="h-role-of-brands-in-decision-making">Role of brands in decision-making</h2>



<p>Brands play a powerful role in consumer decisions, offering familiarity and confidence. This sense of assurance activates reward centers in the brain. </p>



<p>"These relationships to brands are strong and multi-faceted, but they’re not the same relationships that we have with people," noted Dr. Karmarkar.</p>



<p>Understanding these distinctions can help consumers recognize how brand loyalty shapes their choices.</p>



<h2 class="wp-block-heading" id="h-how-companies-trick-our-brains-into-shopping">How companies trick our brains into shopping</h2>



<p>Businesses leverage insights from neuroeconomics to fine-tune marketing strategies. For instance, Dr. Karmarkar's eye-tracking research highlights how product recommendations can <a href="https://www.earth.com/news/mortality-salience-fear-of-death-main-driver-early-halloween-shopping/" target="_blank" rel="noreferrer noopener">influence purchases</a>.</p>



<p>"I've also done some work with eye-tracking - that is, measuring what people look at, and for how long - to help know what information they paid attention to or found useful," said Dr. Karmarkar.</p>



<p>She found that consumers are more likely to buy an item if it is advertised or displayed among other, similar and recommended items on a page.</p>



<p>Dr. Karmarkar used the example of a person <a href="https://www.earth.com/news/happiness-influences-online-shopping-habits/" target="_blank" rel="noreferrer noopener">searching online</a> for a sweater to purchase. "The presence of matched products on the page helps you feel more engaged with a 'sweater-specific' decision," she explained.</p>



<p>On the other hand, mismatched recommendations, such as unrelated items like earrings or home goods, can distract consumers and make them less likely to buy.</p>



<h2 class="wp-block-heading" id="h-alternatives-for-more-sustainable-joy">Alternatives for more sustainable joy</h2>



<p>The same brain regions that respond to the rewards of shopping also react to other pleasures, suggesting alternatives for more sustainable joy.</p>



<p>"It doesn’t have to be a sacrifice," said Dr. Karmarkar. Activities like massages or finding "new-to-me" items through secondhand shopping can provide similar satisfaction without the environmental cost of buying new products.</p>



<p>Our craving for novelty often drives the impulse to shop, as the reward from new items can feel more intense than the ongoing enjoyment of what we already own. Recognizing this tendency can help consumers find rewarding alternatives that align with their values.</p>



<h2 class="wp-block-heading" id="h-becoming-a-conscious-consumer">Becoming a conscious consumer</h2>



<p>Dr. Karmarkar emphasizes the importance of intentional shopping, and highlights how the brain plays a key role in making conscious choices.</p>



<p>"To be a more conscious consumer, think about what your goals are before you get into shopping situations," she advised. Making a list or setting a budget can help curb impulsive buying, as it’s harder to make deliberate choices in the moment.</p>



<p>The research also suggests expanding your "consideration set" - thinking about other ways to spend your money and time. If a product still feels worthwhile after weighing other options, it might be the right choice.</p>



<h2 class="wp-block-heading" id="h-new-perspective-on-shopping">New perspective on shopping</h2>



<p>Dr. Karmarkar’s work reveals the intricate interplay between our brains and shopping behaviors. By understanding the science behind our choices, we can navigate the holiday season - and everyday shopping - with greater awareness.</p>



<p>Whether it’s embracing sustainable habits or rethinking our relationship with brands, the journey toward intentional consumption starts with a deeper understanding of ourselves.</p>



<p>This information is published in a <a href="https://rady.ucsd.edu/why/news/2024/12-09-the-science-of-shopping.html">report</a> by the Rady School of Management.</p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

<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>

<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>

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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



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



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



<p>Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians. </p>
