<p>A recent analysis of the Sapphire Canyon mudstone core, drilled by NASA’s Perseverance rover in July 2024, adds new 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 nonbiological chemistry could also explain the signals.</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 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 nonbiological chemistry could also explain the signals.

<p>Picture a home being restored after years of neglect - that’s the transformation unfolding in the Yangtze River Basin (YRB), where bird habitats are being revitalized. </p>



<p>Over the past few decades, this biodiversity hotspot - home to a rich variety of bird species - has faced severe habitat degradation driven by climate change and human activities.</p>



<p>Despite these challenges, the Yangtze River Basin stands as a testament to the resilience of nature and the power of rehabilitation. Today, we explore a study that offers glimmers of hope - a story that highlights the possibilities of resilience, restoration, and renewal.</p>



<p>The research was a collaborative effort by scientists from the <a href="https://www.nies.org/ywz/" target="_blank" rel="noreferrer noopener">Nanjing Institute of Environmental Sciences</a>, associated with China's Ministry of Ecology and Environment, and their colleagues at <a href="https://www.princeton.edu" target="_blank" rel="noreferrer noopener">Princeton University</a>.</p>



<h2 class="wp-block-heading" id="h-biodiversity-challenges-in-the-yangtze-river">Biodiversity challenges in the Yangtze River</h2>



<p>"The Yangtze River Basin (YRB) is an area of economic importance in China's development and is also one of the key hotspots of global biodiversity," noted the researchers.</p>



<p>"As the world's third largest river, the Yangtze supports a population of 900 million (or more than 60% of the country), and it harbors a large proportion of China's biodiversity, with at least 14,000 plant species and 1,731 vertebrate animal species."</p>



<p>The study paints a comprehensive picture of bird diversity in the Yangtze River Basin. Beyond just stating facts, the experts evaluated the effectiveness of prior conservation measures.</p>



<p>For the investigation, the team used the Living Planet Index (LPIO), a tool that offers a multi-faceted understanding of bird populations by taking into account species abundance, richness, and information entropy.</p>



<h2 class="wp-block-heading" id="h-bird-s-eye-view-of-the-yangtze-river">Bird's eye view of the Yangtze River</h2>



<p>The researchers focused on the decade between 2010 and 2020, studying 536 sites across the Yangtze River Basin. They found different trends among these regions.</p>



<p>The findings are mostly encouraging, revealing a 6.12% increase in bird <a href="https://www.earth.com/news/hundreds-of-bird-species-face-extinction-risks-in-the-neotropics/" target="_blank" rel="noreferrer noopener">diversity</a>. The improvement was particularly notable among terrestrial bird species and was echoed in increased functional complexity throughout the YRB.</p>



<p>However, challenges persist. In the downstream parts of the Yangtze River Basin, the researchers noted a 2.83% decrease in bird diversity.</p>



<p>This drop links back to the stark decline in wetland bird species, emphasizing the urgency of established and targeted conservation efforts in these areas.</p>



<h2 class="wp-block-heading" id="h-wetland-restoration-is-crucial">Wetland restoration is crucial</h2>



<p>"Our study provides compelling evidence that targeted conservation efforts can halt the <a href="https://www.earth.com/news/bird-extinctions-shatter-the-harmonious-balance-of-nature/" target="_blank" rel="noreferrer noopener">decline of biodiversity</a>," said lead researcher Wei Liu.</p>



<p>The message is clear: continued monitoring and wetland restoration strategies are critical for safeguarding bird biodiversity in the Yangtze River Basin.</p>



<p>The research presents a replicable model for other regions grappling with similar environmental dilemmas. It shows that targeted conservation work can not only enhance biodiversity but also protect vital ecosystem services that underpin human well-being and economic stability.</p>



<p>"The results will improve our understanding of conservation and restoration programs and their impacts on biodiversity. This in turn can provide insights relevant for conservation policies and planning," said the researchers.</p>



<h2 class="wp-block-heading" id="h-ecological-balance-of-the-yangtze-river">Ecological balance of the Yangtze River </h2>



<p>Spanning over 6,300 kilometers, the Yangtze River is more than just Asia's longest river; it is a lifeline for countless ecosystems. Its vast basin supports a mosaic of habitats, from wetlands and forests to grasslands, creating ideal <a href="https://www.earth.com/news/bird-wings-have-a-surprising-effect-on-island-biodiversity/" target="_blank" rel="noreferrer noopener">conditions for avian species</a> to thrive.</p>



<p>These habitats play a crucial role in global biodiversity, acting as a sanctuary for migratory birds and endemic species.</p>



<p>The Yangtze’s ecological balance has been disrupted over the decades by habitat fragmentation, urbanization, and <a href="https://www.earth.com/news/bird-behavior-productivity-being-directly-impacted-by-climate-change/" target="_blank" rel="noreferrer noopener">climate change</a>. Moreover, wetlands, which serve as vital breeding and feeding grounds for birds, have borne the brunt of human activity.</p>



<p>Despite these challenges, the river's resilience, coupled with targeted conservation measures, offers a glimmer of hope for its future.</p>



<p>"In light of the extant legislation and regulations concerning the protection of the Yangtze River, it is incumbent upon the relevant authorities to devise a comprehensive, large-scale wetland ecological restoration program for the downstream area," concluded the researchers.</p>



<p>"Moreover, additional monitoring sites should be established in the upstream area, with an even distribution across farmland, wetland, forest, and other habitat types."</p>

Bird diversity is rebounding in the Yangtze River Basin

Picture a home being restored after years of neglect -...

<p>Every day, countless cups of coffee leave behind piles of waste and grounds that often end up in landfills. People around the globe are seeking ways to reduce this organic trash, and construction researchers have identified a method that may give old coffee grounds a second life.</p>



<p>By finding innovative solutions, they are turning waste into a tool for advancing sustainability across industries, addressing the issue of waste management, and offering benefits to industries beyond the <a href="https://www.earth.com/news/coffee-production-threatened-by-loss-of-pollinators/" target="_blank" rel="noreferrer noopener">coffee sector</a>.</p>



<p>By reimagining a common byproduct, scientists are opening doors to more sustainable and practical applications for organic waste, thereby transforming a problem into a valuable resource, which could redefine how organic waste is utilized.</p>



<h2 class="wp-block-heading" id="h-turning-coffee-grounds-into-stronger-concrete">Turning coffee grounds into stronger concrete</h2>



<p>RMIT University engineer <a href="https://www.rmit.edu.au/profiles/r/rajeev-roychand" target="_blank" rel="noreferrer noopener">Dr. Rajeev Roychand</a> and his colleagues have demonstrated that processing leftover coffee grounds can make concrete significantly stronger.&nbsp;</p>



<p>To unlock these benefits, researchers placed coffee waste in a low-oxygen environment and heated it to over 350 °F (about 660 °F). This heating method, called pyrolysis, changes the grounds into a carbon-rich material.</p>



<p>The treatment alters the coffee grounds at a molecular level, transforming them into a material that integrates well with concrete. More importantly, it enables the production of stronger concrete with reduced environmental impacts.</p>



<h2 class="wp-block-heading" id="h-why-pyrolysis-is-key">Why pyrolysis is key</h2>



<p>Pyrolysis involves heating organic matter in the absence of oxygen. When coffee waste is treated with this process at 350 °C, it transforms into a substance known as biochar, which carries the advantage of being able to bond effectively with cement.</p>



<p>In general, the construction industry has long faced challenges with resource consumption, particularly related to sand extraction. </p>



<p>Using biochar derived from coffee can replace a portion of the sand that goes into concrete, thus lowering demand for natural sand.</p>



<p>This process not only lessens dependency on finite resources but also aligns with the growing push for sustainable construction practices. </p>



<p>The pyrolyzed <a href="https://www.earth.com/news/coffee-flavor-can-be-improved-with-a-simple-trick/" target="_blank" rel="noreferrer noopener">coffee</a> biochar creates a porous structure that improves the way concrete holds together under stress. </p>



<p>This method provides a dual benefit: finding a productive use for waste while simultaneously addressing the ecological impacts of sand extraction.</p>



<h2 class="wp-block-heading" id="h-reducing-organic-waste-and-emissions">Reducing organic waste and emissions</h2>



<p>Experts <a href="https://ico.org/resources/trade-statistics-tables/" target="_blank" rel="noreferrer noopener">estimate</a> that global coffee consumption generates around 10 billion kilograms (22 billion pounds) of spent grounds each year. Much of this waste takes up precious space in landfills, while also releasing methane and carbon dioxide.&nbsp;</p>



<p>Methane is considered to be a more harmful greenhouse gas than carbon dioxide over a 100-year period. Hence, diverting this waste toward sustainable uses could significantly reduce greenhouse gas emissions. </p>



<p>Ultimately, with coffee consumption so widespread, even small changes in recycling practices could have far-reaching effects on the environment.</p>



<p>“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases,” said <a href="https://www.sciencedirect.com/science/article/pii/S0959652623023636" target="_blank" rel="noreferrer noopener">Roychand</a>. By recycling coffee grounds, researchers hope to mitigate these environmental impacts while improving concrete’s quality.</p>



<h2 class="wp-block-heading" id="h-indigenous-perspective-on-sustainability">Indigenous perspective on sustainability</h2>



<p>“Inspiration for my research, from an Indigenous perspective, involves Caring for Country,” said RMIT engineer and co-researcher <a href="https://www.rmit.edu.au/news/all-news/2022/august/indigenous-researcher-ppe-innovation" target="_blank" rel="noreferrer noopener">Dr. Shannon Kilmartin-Lynch</a>.</p>



<p>Sustainable practices that keep organic waste from landfills can protect ecosystems, minimize pollution, and preserve natural resources. </p>



<p>This philosophy integrates cultural respect for the environment with cutting-edge engineering techniques. Using coffee biochar in construction aligns with this idea of managing resources more responsibly.</p>



<h2 class="wp-block-heading" id="h-will-this-really-work">Will this really work?</h2>



<p>The coffee-biochar blend requires further testing to confirm its performance over extended periods. Scientists want to know how it stands up to water exposure, freeze-and-thaw cycles, and constant use.</p>



<p>These durability tests will help determine whether biochar-infused <a href="https://www.earth.com/news/recycled-cement-is-an-absolute-miracle-to-lower-concrete-emissions/" target="_blank" rel="noreferrer noopener">concrete</a> can meet the rigorous demands of modern infrastructure projects.</p>



<p>They are also planning to work with different types of organic waste (like wood scraps, food leftovers, and agricultural byproducts) to see if these can also be converted into materials that improve concrete’s structural properties.</p>



<p>These assessments are critical for determining whether the material can be used in large-scale construction projects. </p>



<p>The research team is committed to exploring the practicality of biochar-based concrete under real-world conditions to ensure its reliability and safety.</p>



<h2 class="wp-block-heading" id="h-future-of-coffee-grounds-and-concrete">Future of coffee grounds and concrete</h2>



<p>As buildings rise and infrastructure expands, the search for more sustainable practices will become even more urgent. This approach of adding coffee biochar to concrete could contribute to the circular economy.</p>



<p>Transforming a problematic waste into a valuable input, is the first push of many required to reduce reliance on raw materials such as natural sand. </p>



<p>The example of this approach sets the stage for industries to adopt similar methods, encouraging broader adoption of waste-to-resource strategies.</p>



<p>Such actions promise to lessen the environmental strain while boosting the long-term resilience of <a href="https://www.earth.com/news/how-ancient-romans-made-such-incredibly-durable-concrete-is-no-longer-a-mystery/" target="_blank" rel="noreferrer noopener">construction methods</a>.</p>



<p>Through continued collaboration between scientists, policymakers, and businesses, innovations like this have the potential to reshape the way we think about resources. </p>



<p>By connecting waste management to infrastructure, this research could redefine sustainability in the modern era.</p>



<p>The research findings were published in the <em><a href="https://www.sciencedirect.com/science/article/pii/S0959652623023636" target="_blank" rel="noreferrer noopener">Journal of Cleaner Production</a></em>.</p>

Adding coffee grounds during the construction process could reinforce buildings

Every day, countless cups of coffee leave behind piles of...

<p>For decades, paleontologists have been debating how and when the era of dinosaurs began, armed mostly with fragmented fossil records and theories.</p>



<p>The widely accepted belief is that dinosaurs first originated on Gondwana, the southern portion of the ancient supercontinent Pangea. </p>



<p>For millions of years, their existence was thought to be confined to this region before they gradually spread to Laurasia, the northern part of Pangea.</p>



<p>This theory suggests that dinosaurs established themselves in the south long before leaving any evidence of their presence in the Northern Hemisphere. A remarkable discovery in Wyoming, however, is changing that narrative.</p>



<h2 class="wp-block-heading" id="h-oldest-dinosaur-in-north-america">Oldest dinosaur in North America </h2>



<p>In 2013, a team from the <a href="https://www.wisc.edu" target="_blank" rel="noreferrer noopener">University of Wisconsin-Madison</a> uncovered fossil remains in the Popo Agie Formation, a region near the equator in ancient Laurasia. </p>



<p>After years of painstaking analysis, the researchers identified the fossils as belonging to a new <a href="https://www.earth.com/news/new-tracks-discovered-on-uks-dinosaur-highway/" target="_blank" rel="noreferrer noopener">dinosaur</a> species:&nbsp;<em>Ahvaytum bahndooiveche</em>.</p>



<p>This dinosaur, estimated to be 230 million years old, is now the oldest known dinosaur from Laurasia, challenging the idea that dinosaurs only thrived in the Southern Hemisphere during this time.</p>



<p>Dr. Dave Lovelace, a scientist at the <a href="https://museum.geoscience.wisc.edu" target="_blank" rel="noreferrer noopener">UW Geology Museum</a>, emphasized the significance of the discovery. "We have, with these fossils, the oldest equatorial dinosaur in the world - it's also North America's oldest dinosaur," he said.</p>



<h2 class="wp-block-heading" id="h-laurasia-north-america-and-dinosaurs">Laurasia, North America, and dinosaurs</h2>



<p>Laurasia was one of two supercontinents that formed during the late <a href="https://www.earth.com/news/500-million-year-old-trilobites-fossils-preserved-in-volcanic-ash/" target="_blank" rel="noreferrer noopener">Paleozoic</a> and early <a href="https://www.earth.com/news/dinosaurs-were-not-the-only-animals-that-grew-fast-during-the-mesozoic/" target="_blank" rel="noreferrer noopener">Mesozoic</a> eras. It was made up of what are now North America, Europe, and Asia.</p>



<p>Around 200 million years ago, Earth’s landmasses were all connected as part of a giant supercontinent called Pangaea. Over time, Pangaea started to break apart, and Laurasia emerged as the northern part of the split.</p>



<p>While it was a vast landmass, it wasn’t just one giant chunk of land - it was split into several regions that would eventually evolve into the continents we know today.</p>



<p>As Laurasia broke apart and drifted into its current position, it played a major role in shaping the world’s geography. </p>



<p>The separation of Laurasia from the southern supercontinent, <a href="https://www.earth.com/earthpedia-articles/supercontinents-101-pannotia-gondwana-and-pangea/" target="_blank" rel="noreferrer noopener">Gondwana</a>, led to the creation of the Atlantic Ocean, which opened up between North America and Europe. </p>



<p>The shifting of Laurasia also influenced global climates and ecosystems, setting the stage for the diverse life forms that would appear in the following millions of years.</p>



<h2 class="wp-block-heading" id="h-characteristics-of-the-dinosaur-fossil">Characteristics of the dinosaur fossil</h2>



<p>Far from the towering giants of later eras,&nbsp;<em>Ahvaytum bahndooiveche</em>&nbsp;was modest in size. </p>



<p>"It was basically the size of a chicken but with a really long tail," Dr. Lovelace explained. Measuring just over one foot tall and three feet long, this <a href="https://www.earth.com/news/the-extinction-of-dinosaurs-was-not-caused-by-volcanic-eruptions/" target="_blank" rel="noreferrer noopener">early dinosaur</a> likely lived an omnivorous lifestyle, similar to its sauropod relatives.</p>



<p>Although the fossil record for&nbsp;<em>Ahvaytum bahndooiveche</em>&nbsp;is incomplete, the team's research places this species in a critical period following the Carnian pluvial episode. </p>

<p>This climatic event, which occurred 234 to 232 million years ago, drastically altered the environment - turning vast, arid deserts into lush and fertile landscapes.</p>



<p>These changes created more hospitable habitats, which likely played a key role in encouraging the diversification and spread of <a href="https://www.earth.com/news/what-did-dinosaurs-sound-like/" target="_blank" rel="noreferrer noopener">early dinosaurs</a>. The period marked an important chapter in dinosaur evolution, as species began to adapt to these new and thriving ecosystems.</p>



<h2 class="wp-block-heading" id="h-timeline-of-dinosaur-evolution">Timeline of dinosaur evolution</h2>



<p>Using high-precision radioisotopic dating, the scientists determined that&nbsp;<em>Ahvaytum bahndooiveche</em>&nbsp;lived in Laurasia about 230 million years ago, making it one of the oldest known dinosaurs from the Northern Hemisphere.</p>



<p>Older tracks in the same region suggest that <a href="https://www.earth.com/news/rare-triassic-fossil-gondwanax-paraisensis-may-rewrite-history-of-dinosaurs/" target="_blank" rel="noreferrer noopener">dinosaur</a>-like creatures were present there even earlier, challenging previous beliefs that dinosaurs originated solely in the Southern Hemisphere before spreading northward.</p>



<p>This discovery alters the timeline of dinosaur evolution in North America while highlighting a significant collaboration with the Eastern Shoshone Tribe.</p>



<p>The species' name,&nbsp;<em>Ahvaytum bahndooiveche</em>, meaning "long ago dinosaur," honors the Indigenous people whose ancestral lands were home to the fossil site. </p>



<p>This partnership reflects a deeper respect for cultural heritage, integrating Indigenous language and perspectives into the scientific process.</p>



<h2 class="wp-block-heading" id="h-new-model-for-research">New model for research</h2>



<p>Amanda LeClair-Diaz, an Eastern Shoshone and Northern Arapaho tribal member, highlighted the importance of this partnership. </p>



<p>"The continuous relationship developed between Dr. Lovelace, his team, and our community is one of the most important outcomes of this discovery," said LeClair-Diaz.</p>



<p>"Typically, the research process in communities, especially Indigenous communities, has been one sided, with the researchers fully benefiting from studies. The work we have done with Dr. Lovelace breaks this cycle and creates an opportunity for reciprocity in the research process."</p>



<h2 class="wp-block-heading" id="h-legacy-of-collaboration">Legacy of collaboration</h2>



<p>The discovery of&nbsp;<em>Ahvaytum bahndooiveche</em>&nbsp;holds significance beyond just expanding our scientific knowledge. It challenges long-held beliefs about <a href="https://www.earth.com/news/qunkasaura-pintiquiniestra-new-sauropod-dinosaur-discovered-in-spain/" target="_blank" rel="noreferrer noopener">dinosaur</a> origins and encourages scientists to rethink established theories. </p>



<p>Additionally, this finding highlights the value of incorporating diverse perspectives in research. </p>



<p>By collaborating with the Eastern Shoshone Tribe in naming the dinosaur and respecting the cultural heritage of the land where the fossils were found, the project sets a new standard for inclusive and ethical scientific practices. </p>

Dinosaur discovery in North America is completely rewriting their history

For decades, paleontologists have been debating how and when the...

<p>Beneath the ocean’s surface, fisheries rely on the health of vibrant and complex ecosystems. Coral reefs, in particular, are the center of underwater life. </p>



<p>They provide essential food and shelter to countless marine species, making them crucial for maintaining marine biodiversity and ecosystem balance. Without coral reefs, many sea creatures would struggle to survive, threatening the entire marine environment.</p>



<p>But these individual ecosystems are in deep trouble. And that can have a ripple effect, impacting not just marine life, but human livelihoods too - particularly in the fisheries sector.</p>



<h2 class="wp-block-heading" id="h-coral-decline-affects-fisheries">Coral decline affects fisheries </h2>



<p>According to a recent study from the Woods Hole Oceanographic Institution (<a href="https://www.whoi.edu/who-we-are/" target="_blank" rel="noreferrer noopener">WHOI</a>), a decline in live <a href="https://www.earth.com/news/extreme-coral-bleaching-event-prompts-emergency-un-session/" target="_blank" rel="noreferrer noopener">coral</a> habitats directly influences the yield of marine fisheries.</p>



<p>The researchers explored the yield trends of nine fisheries in the vicinity of Australia's iconic Great Barrier Reef from 2016 to 2020.</p>



<p>The team uncovered a worrying trend- significant losses could be the unfortunate reality if coral restoration efforts are not amped up.</p>



<p>In 2024, the Great Barrier Reef faced a severe bleaching episode, one of the worst in its history. During this event, an alarming 73% of surveyed reefs showed signs of bleaching, as per the Australian Marine Institute.</p>



<h2 class="wp-block-heading" id="h-coral-bleaching-threat-to-marine-biodiversity">Coral bleaching: Threat to marine biodiversity</h2>



<p>Coral reefs depend on microscopic algae, zooxanthellae, for survival and their bright hues. When ocean temperatures rise, the coral gets stressed and expels these crucial algae, leading to <a href="https://www.earth.com/news/60-percent-global-coral-reefs-face-bleaching-rising-temperatures/" target="_blank" rel="noreferrer noopener">bleaching</a>.</p>



<p>The persistent warming trend means the algae may not return, leaving the coral bleached and on the brink of death. </p>



<p>Over the past 30 years, a staggering 19% of the world's coral reef area has been lost due to bleaching induced by ocean warming.</p>



<h2 class="wp-block-heading" id="h-fish-and-famine-lives-and-livelihoods-at-risk">Fish and famine: Lives and livelihoods at risk</h2>



<p>“This rapid loss of <a href="https://www.earth.com/news/the-worlds-largest-coral-bleaching-event-is-now-underway/" target="_blank" rel="noreferrer noopener">coral</a> will force fish capable of living independently of them to move elsewhere. Less concentrated populations can lead to smaller yields for fisheries," noted Marine (Yaqin) Liu, an environmental economist at WHOI.</p>



<p>When it comes to fish species that directly rely on reefs for food or shelter, like butterflyfish and coral trout, their yield will deplete in parallel with their population decline.</p>



<p>And it's not just marine life at risk. Many fisheries, and the communities they support, are bound for turbulent waters. </p>



<p>The study pointed out coral trout and saddletail snappers, which heavily rely on outer-shelf reefs as their primary habitat, as the two most vulnerable fisheries. </p>



<p>If the live coral cover of the Great Barrier Reef reduces from 30% to 25%, the maximum sustainable yield of coral trout and saddletail snappers would drop by 8% and 19%, respectively. </p>



<p>An even steeper decline from 10% to 5% live coral cover could result in losses of 27% and a startling 56% for coral trout and saddletail snapper fisheries.</p>



<h2 class="wp-block-heading" id="h-coral-decline-economic-impact-on-fisheries">Coral decline: Economic impact on fisheries</h2>



<p>These losses are not only ecological but economic. Professor Qingran Li, from <a href="https://www.clarkson.edu" target="_blank" rel="noreferrer noopener">Clarkson University</a> in New York, shed light on the economic toll.</p>



<p>"Coral trout and saddletail snapper are part of Queensland, Australia’s line fishery, an industry with $27-31 million gross value," said Professor Li.</p>



<p>"While this methodology of this study does not lend itself to making dollar predictions, we can expect a decline in fishing yields to have substantial economic impacts, such as loss of jobs and reduced export."</p>



<h2 class="wp-block-heading" id="h-preserving-coral-reefs-and-fisheries">Preserving coral reefs and fisheries</h2>



<p>As <a href="https://www.earth.com/news/coral-reefs-could-vanish-if-temperatures-continue-to-rise/" target="_blank" rel="noreferrer noopener">coral reefs</a> continue to battle warmer waters and bleaching events become more frequent, their role in nurturing marine life and safeguarding coastal communities from major storms becomes increasingly crucial. Their contribution to tourism and fishing revenues is equally significant.</p>



<p>These ecosystems also act as natural barriers, reducing the impact of storm surges and protecting vulnerable coastlines from erosion.</p>



<p>Data-driven climate change advocacy is so essential. "Responsible fisheries are already safeguarding coral <a href="https://www.earth.com/news/coral-bleaching-hinders-reproduction-in-popular-reef-species/" target="_blank" rel="noreferrer noopener">reefs</a> by integrating sustainable approaches, but human impacts like ocean warming and acidification further threaten coral reefs and fisheries yields," said Liu.</p>



<p>"WHOI’s Reef Solutions Team continues study and develop innovative ways to restore and strengthen coral reefs, with a goal of taking successful learnings and implementing them globally."</p>

Bleaching effect: Coral loss threatens fisheries and livelihoods

Beneath the ocean’s surface, fisheries rely on the health of...

<p>The Mediterranean Sea has always been a hotspot for marine life and many crustacean species. It connects diverse regions and hosts a blend of species shaped by environmental shifts and human activities. </p>



<p>New data about organisms arriving from distant waters has sparked fresh interest among researchers studying these coastal zones. </p>



<p>A recent investigation highlights <a href="https://www.earth.com/wp-content/uploads/2025/01/new-species-crustaceans-mediterranean-waters.jpg" target="_blank" rel="noreferrer noopener">previously unrecorded crustaceans</a> that have been found in areas of the Mediterranean. This may spark changes to our understanding of ecosystem structure.</p>



<h2 class="wp-block-heading" id="h-humans-encroaching-on-marine-life">Humans encroaching on marine life</h2>



<p>Ports and piers are common along coastlines worldwide. They accommodate ships and stimulate commerce, but they can also serve as convenient footholds for newly arrived <a href="https://www.earth.com/news/alarming-climate-impacts-threaten-key-marine-species/" target="_blank" rel="noreferrer noopener">marine species</a>. </p>



<p>As humans construct new docks and other artificial surfaces, unexpected marine travelers and crustacean species may find places to settle. </p>



<p>Some hitch rides on vessels, while others arrive in ballast water. Once they find a suitable location, they can spread and compete with established indigenous life forms. </p>



<p>The research focused on organisms that were attached to local reefs and artificial structures. Findings showed that three species (<a href="https://www.gbif.org/species/4309967" target="_blank" rel="noreferrer noopener"><em>Athanas dimorphus</em></a><em>, </em><a href="https://www.gbif.org/species/2227601" target="_blank" rel="noreferrer noopener"><em>Pilumnus longicornis</em></a><em>, </em>and<em> </em><a href="https://www.gbif.org/species/216384541" target="_blank" rel="noreferrer noopener"><em>Pilumnus savignyi</em></a>) had never before been documented in the Mediterranean Sea. </p>



<p>This discovery opens the door to new questions about how these crustaceans ended up along Israel’s shore.</p>



<h2 class="wp-block-heading" id="h-importance-of-early-detection">Importance of early detection</h2>



<p>A method called <a href="https://naturalhistory.si.edu/research/global-arms-program#:~:text=What%20is%20an%20Autonomous%20Reef,sample%20without%20destroying%20natural%20habitat." target="_blank" rel="noreferrer noopener">ARMS</a> (Automated Reef Monitoring Structures) assists scientists to identify the presence of species that are not immediately visible. </p>



<p>ARMS units look like simple boxes or frames, but they attract tiny organisms and <a href="https://www.earth.com/news/climate-change-is-impacting-marine-life-more-than-we-realized/" target="_blank" rel="noreferrer noopener">other marine life</a> that settle within their layers. </p>



<p>By placing these devices along Israel's coast and checking them regularly, researchers can note newcomers. Early detection matters because once a non-native creature gains a foothold, it can be tough to remove.&nbsp;</p>



<p>If there is a time lag between identifying a new species that is present and trying to remove it or mitigate its effects, the process of removal or mitigation becomes more resource-intensive. </p>



<h2 class="wp-block-heading" id="h-invasive-crustacean-species">Invasive crustacean species</h2>



<p>"Invasive species can have impacts on our marine industries, such as growing on marine structures, killing or competing with marine aquaculture species and by spreading disease," said researchers at the <a href="https://www.plymouth.ac.uk/discover/what-are-invasive-species" target="_blank" rel="noreferrer noopener">University of Plymouth</a>.<br><br>According to the Department for Environment, Food and Rural Affairs (DEFRA), tackling <a href="https://www.earth.com/news/melting-glaciers-unleash-invasive-species-into-unexpected-areas/">invasive species</a> costs the U.K. approximately <a href="https://publications.parliament.uk/pa/cm201919/cmselect/cmenvaud/88/88.pdf" target="_blank" rel="noreferrer noopener">1.8 billion pounds annually</a>. </p>



<p>On a global scale, the cost is estimated to exceed $100 billion per year, which surpasses the financial toll of natural disasters.</p>



<p>These findings line up with the concerns raised by Professor <a href="https://smnh.tau.ac.il/en/research-at-smnh-2/scientific-staff/bella-galil/" target="_blank" rel="noreferrer noopener">Bella S. Galil </a>and her colleagues, who stress the need for consistent programs that could give policymakers a chance to take swift action.</p>



<h2 class="wp-block-heading" id="h-variety-of-new-faces">Variety of new faces</h2>



<p>The study does not only mention the three species that are fresh to the entire region. Two additional species, <em>Sphaerozius nitidus </em>and<em> Liomera rugipes</em>, also appear to be new to Israel’s coast.&nbsp;</p>



<p>Researchers see this as further proof that non-native animals can set up shop wherever conditions suit them. These crustaceans may slip into a niche or bring new challenges to <a href="https://www.earth.com/news/meet-melita-panda-the-black-and-white-crustacean-shrimp/" target="_blank" rel="noreferrer noopener">local ecological structures</a>.<br><br>The nuances of whether they will harm native habitats remain unclear, though similar introductions in other parts of the world have led to shifts in local species interactions.</p>



<h2 class="wp-block-heading" id="h-why-new-crustacean-species-matter">Why new crustacean species matter</h2>



<p>Foreign organisms can be more than a scientific curiosity. They can bring serious economic and environmental consequences. </p>



<p>Sometimes, they feed on shellfish or disrupt fisheries. Tourism can also suffer if non-native pests degrade coral reefs or affect coastal recreation. </p>



<p>While not all alien species become full-blown problems, the possibility remains. That is why prompt discovery is so significant.&nbsp;</p>



<p>“Invasive alien species are a major cause of biodiversity loss,” notes the <a href="https://iucn.org/our-work/biodiversity" target="_blank" rel="noreferrer noopener">IUCN</a> (International Union for Conservation of Nature).</p>



<p>When local ecosystems lose certain species to competition or predation, the broader food web may suffer.</p>



<h2 class="wp-block-heading" id="h-calls-for-wider-monitoring">Calls for wider monitoring</h2>



<p>Scientists advise that Israel’s National Monitoring Program increase its capacity to track these types of arrivals. Installing ARMS at newly developed coastal sites and shipping points could help gather more consistent information.&nbsp;</p>



<p>Some experts also believe that a wider regional push would be beneficial. If neighboring countries used the same approaches, they could share results and identify potential issues sooner. </p>



<p>This might prevent a <a href="https://www.earth.com/news/new-deep-sea-crustacean-species-discovered-in-the-bahamas/" target="_blank" rel="noreferrer noopener">newly arrived crustacean</a> or fish from spreading unnoticed across international boundaries. </p>



<h2 class="wp-block-heading" id="h-what-s-next-for-these-new-crustacean-species">What's next for these new crustacean species?</h2>



<p>In addition to official programs, private operators of marinas or industrial sites could adopt more thorough procedures. Using ARMS as an early warning tool, they might recognize invasive hitchhikers before they disrupt existing habitats.&nbsp;</p>



<p>The reason many professionals keep sounding the alarm is clear. Sometimes, small changes in ocean life pass under the radar until entire fisheries notice declines in catch or find that new diseases have entered the ecosystem. Swift, standardized methods can act like an insurance plan for marine environments.</p>



<p>Monitoring and intervention go hand in hand. Information from the ARMS approach can guide where to focus limited resources. </p>



<p>If a newly arrived species shows signs of becoming a hazard, an immediate response might keep that threat under control. </p>



<p>The recent discoveries in the <a href="https://www.earth.com/news/the-mediterranean-nearly-lost-all-of-its-water-6-million-years-ago/">Mediterranean</a> mark a call to action for all stakeholders. It might seem daunting, but the tools and knowledge are now available to keep this region healthier and more stable in the years ahead.&nbsp;</p>



<p>Details of the full study were published in the <a href="https://www.reabic.net/journals/mbi/2024/4/MBI_2024_Galil_etal.pdf">Management of Biological Invasions</a>. </p>

New invasive crustacean species discovered in the Mediterranean

The Mediterranean Sea has always been a hotspot for marine...

<p>We’ve all seen houseplants tucked in corners far from windows or lush greenery growing under dense tree canopies. Yet, these plants manage to grow and thrive in shade without direct sunlight. How do they do it?</p>



<p>New research reveals that shaded plants capture more light than previously believed. Scientists from Utrecht University and Wageningen University &amp; Research (WUR) found that these plants effectively use light beyond the visible spectrum. </p>



<p>Published in the journal <em>Plant Cell &amp; Environment</em>, the findings could transform photosynthesis research and greenhouse horticulture practices.</p>



<p>“When you have a better understanding of how different colors of light affect photosynthesis and plant growth, you can help growers develop smart ways to supplement natural sunlight with colored light,” noted the researchers.</p>



<h2 class="wp-block-heading" id="h-shaded-plants-capture-far-red-light">Shaded plants capture far-red light </h2>



<p>Shaded plants benefit from light that filters through the leaves of <a href="https://www.earth.com/news/scientists-uncover-how-plants-grow-wider-not-just-taller/" target="_blank" rel="noreferrer noopener">plants</a> above them. When sunlight hits the upper plant leaves, they absorb most of the light for photosynthesis but allow some light to pass through. </p>



<p>This unabsorbed light primarily consists of green and far-red wavelengths, which are less useful to the upper plants but become crucial for the plants below.</p>



<p>Far-red light, in particular, falls within the 700–750 nm range of the light spectrum. Unlike visible light, which plants predominantly use for photosynthesis, far-red light was previously thought to have little impact. </p>



<p>However, the study reveals that shaded plants have adapted to use far-red light effectively for photosynthesis, allowing them to survive and grow even in low-light environments. This ability is vital for plants in dense forests or closely planted crops, where direct sunlight is scarce.</p>



<h2 class="wp-block-heading" id="h-photosynthesis-in-shaded-plants">Photosynthesis in shaded plants</h2>



<p>“Until now, researchers have seldom considered the possibility that plants utilize far-red light for photosynthesis,” said WUR PhD candidate <a href="https://research.wur.nl/en/persons/tinko-jans" target="_blank" rel="noreferrer noopener">Tinko Jans</a>.</p>



<p>Conventional experiments suggested that photosynthesis relied mainly on visible wavelengths (400–700 nm). </p>



<p>However, this study reveals that far-red light significantly <a href="https://www.earth.com/news/booster-plant-gene-discovery-amplifies-plant-growth-up-to-200-percent/" target="_blank" rel="noreferrer noopener">boosts photosynthesis</a> when combined with small amounts of visible light. The team developed a new method to measure and model this contribution.</p>



<h2 class="wp-block-heading" id="h-plants-grow-taller-using-far-red-light">Plants grow taller using far-red light</h2>



<p>Far-red light also affects plant behavior, triggering a “shade avoidance response.” “Many plants react to a relative increase in far-red light by growing straight up, to win the competition for light,” Jans explained.</p>



<p>This response benefits horticulturists, allowing plants to grow closer together in limited spaces.</p>



<p>Recent advances in LED technology have enabled researchers to study far-red light more effectively. </p>



<p>“In earlier experiments, we showed that shade <a href="https://www.earth.com/news/how-do-plants-grow-more-branches-and-become-bushy/" target="_blank" rel="noreferrer noopener">plants grow faster</a> when supplemented with far-red light from LEDs,” noted Utrecht University environmental scientist <a href="https://www.uu.nl/staff/HJdeBoer" target="_blank" rel="noreferrer noopener">Hugo de Boer</a>, who initiated the study.</p>



<p>The findings highlight how controlled light environments can optimize plant growth.</p>



<h2 class="wp-block-heading" id="h-considering-the-full-light-spectrum">Considering the full light spectrum </h2>



<p>The scientists faced challenges in studying the role of far-red light in photosynthesis because existing models only considered visible light (400–700 nm) as the primary <a href="https://www.earth.com/news/world-soil-day-2024-protecting-our-planets-lifeline/" target="_blank" rel="noreferrer noopener">contributor to plant growth</a>.</p>



<p>Far-red light was largely overlooked in traditional research and calculations.</p>



<p>“It turned out to be much more difficult to quantify the color effect on photosynthesis,” explained Hugo de Boer, as earlier models and measurement methods were not designed to account for the influence of far-red light.</p>



<p>To overcome this, the researchers adapted widely used photosynthesis models to include far-red light. They combined measurements of photosynthesis with data from the full spectrum of light reaching plant leaves. </p>



<p>This updated approach allowed them to accurately demonstrate how far-red light, when integrated with visible light, significantly enhances photosynthesis and supports plant growth. </p>



<p>This breakthrough highlights the importance of considering the full light spectrum in both research and agricultural practices.</p>



<h2 class="wp-block-heading" id="h-greenhouse-crop-cultivation">Greenhouse crop cultivation</h2>



<p>The research highlights a previously underestimated <a href="https://www.earth.com/news/predicting-how-climate-change-will-alter-plant-growth-cycles/" target="_blank" rel="noreferrer noopener">factor in plant growth</a>: the role of far-red light in photosynthesis.</p>



<p>Far-red light was once thought to contribute little to photosynthesis. However, the study demonstrates that plants can effectively use this light, especially when combined with visible light, to enhance their growth.</p>



<p>The findings hold significant potential for greenhouse horticulture. By integrating far-red light into lighting strategies, growers can optimize plant growth even in shaded or crowded environments where sunlight is limited.</p>



<p>This approach could improve crop yields while reducing the energy and space required for cultivation.</p>



<p>Leveraging far-red light offers a smarter, more sustainable method of farming, allowing plants to thrive in conditions that were previously considered suboptimal. This advancement could transform modern agriculture, making it more efficient and environmentally friendly.</p>



<p>The study is published in the journal <em><a href="https://onlinelibrary.wiley.com/doi/10.1111/pce.15340" target="_blank" rel="noreferrer noopener">Plant Cell &amp; Environment</a>.</em></p>

Plants living in the shade get much more light than previously believed

We’ve all seen houseplants tucked in corners far from windows...

<p>Nature often surprises us with its ingenious adaptations, and the cricket frog is no exception. Native to Virginia and North Carolina, these tiny frogs display an ability that seems almost magical: moving across water as if it were solid ground. </p>



<p>Known as “skittering,” this behavior has intrigued scientists and inspired visions of futuristic technologies.</p>



<h2 class="wp-block-heading" id="h-capabilities-of-cricket-frogs">Capabilities of cricket frogs</h2>



<p>Jake Socha, a professor of mechanical engineering, and his research team at <a href="https://www.vt.edu" target="_blank" rel="noreferrer noopener">Virginia Tech</a> have examined this phenomenon.</p>



<p>“The humble cricket <a href="https://www.earth.com/news/world-frog-day-addressing-environmental-threats-to-frogs/" target="_blank" rel="noreferrer noopener">frog</a> lives nearby, and yet it still surprised us with its capabilities, further motivating our curiosity to understand the living world,” said Professor Socha.</p>



<p>The research, published in the&nbsp;<em>Journal of Experimental Biology</em>, challenges popular notions about how frogs traverse water.</p>



<p>“Skittering is not actually a well-defined word for this behavior. Part of this research is not only studying this behavior in cricket frogs but to try and give ‘skittering’ a more precise, scientific definition,” explained study lead author and graduate researcher Talia Weiss.</p>



<h2 class="wp-block-heading" id="h-cricket-frogs-don-t-walk-on-water">Cricket frogs don’t walk on water</h2>



<p>Using high-speed cameras shooting at 500 frames per second, the team captured the frogs’ motions in astonishing detail. </p>



<p>Contrary to the idea that these frogs glide effortlessly across water, the footage revealed something unexpected: the frogs sink between each leap.</p>



<p>“It’s fascinating how easily we can be fooled by fast animal movements,” said Professor Socha. “Here, we’re fooled by a <a href="https://www.earth.com/news/frog-saunas-hot-solution-to-fighting-global-amphibian-extinction-apocalypse/" target="_blank" rel="noreferrer noopener">frog</a> that appears like a skipping stone, but is actually jumping and dunking multiple times in a row.”</p>



<h2 class="wp-block-heading" id="h-leaping-frogs-resemble-dolphins-jumping">Leaping frogs resemble dolphins jumping</h2>



<p>The movement of cricket frogs, often mistaken for walking on water, is better described as "porpoising," a motion similar to the way dolphins leap in and out of the water. </p>



<p>Unlike true walking, this behavior involves distinct stages within each jump cycle, which researchers broke down into four key phases:</p>



<ol class="wp-block-list">
<li><strong>Takeoff</strong>: The frog begins completely submerged in water. Using its powerful hind legs, it pushes off against the water, propelling its body upward and into the air. This explosive motion provides the energy needed for the leap.</li>



<li><strong>Aerial</strong>: While in mid-air, the frog's legs remain extended, providing balance and stability during its short flight. This phase gives the impression that the frog is gracefully skipping across the water.</li>



<li><strong>Re-entry</strong>: The frog's front legs are the first to contact the water as it descends. The rest of the body follows, creating a splash and breaking the water's surface as it sinks back under.</li>



<li><strong>Recovery</strong>: Once submerged, the frog rapidly retracts its legs to prepare for the next jump. This resetting phase ensures the frog is ready to push off again almost immediately.</li>
</ol>



<p>Each of these phases occurs in less than a second, allowing the frog to perform up to eight consecutive jumps in quick succession. This rapid, repetitive motion creates the illusion that the <a href="https://www.earth.com/news/common-economic-strategy-could-save-endangered-frogs/" target="_blank" rel="noreferrer noopener">frog</a> is walking or skipping on water, though it is actually sinking and leaping continuously. </p>



<p>The efficiency and speed of these movements highlight the cricket frog’s unique adaptations for this behavior.</p>



<h2 class="wp-block-heading" id="h-frog-movement-inspires-robots">Frog movement inspires robots</h2>



<p>Understanding the mechanics of skittering has implications far beyond biology. This unique locomotion could inspire innovations in robotics and engineering. For instance, amphibious drones designed for water testing or rescue missions might mimic the cricket frog’s efficient movements.</p>



<p>“Frogs are great jumpers, but most of them don’t exhibit this porpoising behavior, and we still don’t know why,” noted Professor Socha. “Is there something special about the frog’s leap, or is it simply a matter of small body size?”</p>



<p>This research highlights how studying even the <a href="https://www.earth.com/news/puddle-frogs-have-a-secret-weapon-against-climate-change/" target="_blank" rel="noreferrer noopener">smallest creatures</a> can lead to big discoveries. The cricket frog’s seemingly simple movement holds secrets that may shape the future of technology.</p>

<p>Cricket frogs may be small, but their anatomy is a masterpiece of adaptation. Their ability to skitter across water is no accident; it’s the result of finely tuned physical traits that allow them to excel at leaping, sinking, and jumping again.</p>



<h3 class="wp-block-heading" id="h-powerful-hind-legs">Powerful hind legs</h3>



<p>The cricket frog’s hind legs are disproportionately long and muscular for its tiny body. These legs provide the explosive force needed to propel the frog both on land and through water. </p>



<p>Their large, well-developed muscles allow for rapid extension and retraction, making it possible to perform consecutive jumps in quick succession.</p>



<h3 class="wp-block-heading" id="h-lightweight-body">Lightweight body</h3>



<p>Weighing less than many other frogs, cricket frogs benefit from a lightweight frame. This reduces resistance when they re-enter the water after a jump, helping them maintain momentum. Their small size also means they create minimal drag during movement.</p>



<h3 class="wp-block-heading" id="h-flexible-joints">Flexible joints</h3>



<p>Their joints, particularly in the hind legs, are highly flexible. This flexibility enables the frogs to fully extend their legs during the takeoff phase and then rapidly retract them underwater to reset for the next leap.</p>



<h3 class="wp-block-heading" id="h-streamlined-body-shape"><strong>Streamlined body shape</strong></h3>



<p>The cricket frog’s body is slightly flattened, which may help reduce resistance during re-entry into the water. This streamlined shape allows for smoother transitions between aerial and submerged phases of their movement.</p>



<h3 class="wp-block-heading" id="h-skin-adaptations">Skin adaptations</h3>



<p>The frog’s skin plays a subtle but critical role. Smooth and water-resistant, it minimizes friction as the frog moves in and out of the water. This feature also helps maintain buoyancy and allows for quicker movement beneath the surface.</p>



<p>Ultimately, the cricket frog’s body is a perfect example of how evolution tailors physical traits to meet specific survival needs. Each aspect of the frogs' anatomy, from powerful legs to streamlined bodies, contributes to their ability to skitter on water.&nbsp;</p>

Cricket frogs can literally walk on water as if it were dry land

Nature often surprises us with its ingenious adaptations, and the...

<p>Have you ever found yourself in a heated discussion with someone of the opposite sex and thought - "it's like we're wired differently"? Well, a recent study from the University of Cambridge suggests that male and female brains are indeed wired differently from the time of birth.</p>



<p>This study, one of the largest of its kind, analyzed the brain anatomy of more than 500 newborns using advanced imaging techniques.</p>



<h2 class="wp-block-heading" id="h-difference-in-male-and-female-brains">Difference in male and female brains</h2>



<p>The findings reveal distinct <a href="https://www.earth.com/news/mens-brains-shrink-in-the-evening-and-reset-overnight/" target="_blank" rel="noreferrer noopener">differences in brain structure</a> between male and female infants in both the grey and white matter regions.</p>



<h3 class="wp-block-heading" id="h-grey-matter">Grey matter</h3>



<p>Female newborns typically have more grey matter in their brains. Grey matter is found in the outermost layer of the brain, known as the cortex. </p>



<p>This tissue is essential for key mental functions including memory processing, emotional regulation, and interpreting information.</p>



<p>This could explain why females often excel in recalling memories and displaying emotional awareness, even from a young age.</p>



<h3 class="wp-block-heading" id="h-white-matter">White matter</h3>



<p>Male newborns generally have more white matter in their <a href="https://www.earth.com/news/ai-reveals-the-secret-to-keeping-your-brain-young/" target="_blank" rel="noreferrer noopener">brains</a>. White matter consists of neural pathways that connect different brain regions, creating a network for fast communication. </p>



<p>It serves as the brain’s "superhighway," and supports semsory processing and motor control.</p>



<p>These differences may contribute to males having stronger spatial awareness and better physical coordination early in life.</p>



<h2 class="wp-block-heading" id="h-nature-and-nurture-in-brain-development">Nature and nurture in brain development</h2>



<p>The study indicates that these differences likely originate during prenatal <a href="https://www.earth.com/news/first-complete-map-of-every-neuron-in-the-brain-revealed/" target="_blank" rel="noreferrer noopener">brain development</a> and may become more pronounced as environmental factors interact with biological wiring.</p>



<p>“Because these sex differences are evident so soon after birth, they might in part reflect biological sex differences during prenatal brain development,” explained study lead author Yumnah Khan.</p>



<p>“We took additional factors into account, such as birth weight, to ensure that these differences are specific to the brain and not due to general size differences between the sexes,” added co-author Dr. Alex Tsompanidis.</p>



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



<p>Professor Simon Baron-Cohen, a co-author of the study, emphasized that the findings do not imply superiority of one sex’s brain over the other.</p>



<p>Instead, they shed light on neurodiversity - the concept that different <a href="https://www.earth.com/news/how-does-the-brain-process-experiences-over-time/" target="_blank" rel="noreferrer noopener">brain structures</a> and functions can lead to diverse strengths and ways of thinking.</p>



<p>Professor Baron-Cohen highlights the potential implications of these findings for understanding conditions like autism, which is more frequently diagnosed in males.</p>



<p>The study's insights into sex-based brain differences may help researchers better understand how neurodevelopmental conditions emerge and why they may differ between sexes.</p>



<h2 class="wp-block-heading" id="h-extreme-male-brain-theory">Extreme male brain theory</h2>



<p>In his "extreme male brain theory," Professor Baron-Cohen proposed that males tend to excel at systemizing, which involves identifying patterns, understanding rules, and solving logical problems.</p>



<p>In contrast, females are generally better at&nbsp;empathizing, which includes understanding and responding to the emotions and perspectives of others. </p>



<p>This study aligns with the idea that these differences are rooted in biology, but the real-world implications remain intricate and influenced by numerous factors, including environment and experience.</p>



<p>The study reinforces the idea that male and female <a href="https://www.earth.com/news/how-does-cannabis-use-affect-brain-structure/" target="_blank" rel="noreferrer noopener">brains</a> are distinct but equally valuable. These differences contribute to a broader understanding of human neurodiversity, and help researchers explore conditions like autism and the varied ways in which brains function across sexes.</p>



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



<p>Not all researchers agree on the significance of brain differences between sexes. </p>



<p>A 2021 study by researchers at <a href="https://www.rosalindfranklin.edu" target="_blank" rel="noreferrer noopener">Rosalind Franklin University</a> found that brain structure variations between men and women were negligible when adjusting for size.</p>



<p>A 2013 <a href="https://www.upenn.edu" target="_blank" rel="noreferrer noopener">University of Pennsylvania</a> study noted “striking” differences in neural wiring, while a 2017 study suggested women’s brains are more active - particularly in areas tied to focus and impulse control.</p>



<h2 class="wp-block-heading" id="h-male-and-female-brains-are-distinct">Male and female brains are distinct</h2>



<p>While this study confirms sex-based brain differences from birth, it also reignites the debate over their relevance in adulthood. </p>



<p>The findings highlight the interplay between biology and environment that shapes the way we think, feel, and interact. As researchers continue to explore this topic, one thing is clear: male and female brains are distinct, but equal in complexity and capability.</p>



<p>"These differences do not imply the brains of males and females are better or worse," said Professor Baron-Cohen. They are simply different, and this adds richness to human diversity.</p>



<p>The study is published in the journal <em><a class="" href="http://dx.doi.org/10.1186/s13293-024-00657-5" target="_blank" rel="noreferrer noopener">Biology of Sex Differences</a>.</em></p>

Male and female brains truly are wired completely differently

Have you ever found yourself in a heated discussion with...

<p>A good night’s sleep does more than help you feel rested - it literally clears your mind. New research reveals how deep sleep removes waste buildup in the brain, a process that is crucial for brain health.</p>



<p>However, sleep aids may disrupt this natural “brainwashing” system, raising questions about their long-term effects on cognitive function.</p>



<h2 class="wp-block-heading" id="h-brain-s-built-in-cleanup-system">Brain’s built-in cleanup system</h2>



<p>The glymphatic system is like a <a href="https://www.earth.com/news/how-sleep-transforms-brain-performance/" target="_blank" rel="noreferrer noopener">cleaning service for your brain</a>. Throughout the day, metabolic waste builds up in the brain, including toxic proteins that, if not removed, can lead to neurological issues like Alzheimer’s disease.</p>



<p>The glymphatic system works by using cerebrospinal fluid (CSF), a clear liquid that surrounds the brain and spinal cord, to flush out these harmful substances.</p>



<p>Think of the CSF as water flowing through pipes and washing away debris. This process happens most effectively during deep sleep, when the brain’s cleaning system kicks into high gear.</p>



<p>While scientists have known about the glymphatic system’s existence for years, they didn’t understand exactly what powered it - until now.</p>



<p>Recent research has shown that norepinephrine, a chemical messenger in the brain, is key. During deep sleep, waves of norepinephrine cause blood vessels in the <a href="https://www.earth.com/news/your-brain-literally-changes-based-on-daily-activities-and-lifestyle/" target="_blank" rel="noreferrer noopener">brain</a> to pulse rhythmically. </p>



<h2 class="wp-block-heading" id="h-role-of-norepinephrine-in-brain-cleaning">Role of norepinephrine in brain cleaning</h2>



<p>Danish scientists have uncovered a crucial role for norepinephrine during deep sleep. They found that the brainstem releases waves of norepinephrine roughly every 50 seconds during this sleep phase. </p>



<p>These waves cause blood vessels in the brain to contract and relax rhythmically, much like a pump. This rhythmic movement generates fluid pulses that help cerebrospinal fluid flow through the brain and flush out waste and toxins.</p>



<p>“It’s like turning on the dishwasher before you go to bed and waking up with a clean brain,” explained Maiken Nedergaard, senior author and researcher at the <a href="https://www.rochester.edu" target="_blank" rel="noreferrer noopener">University of Rochester</a> and <a href="https://www.ku.dk/en" target="_blank" rel="noreferrer noopener">University of Copenhagen</a>.</p>



<h2 class="wp-block-heading" id="h-brain-blood-flow-during-sleep">Brain blood flow during sleep</h2>



<p>Nedergaard's team investigated how norepinephrine affects blood flow during sleep. In sleeping mice, they observed that waves of norepinephrine align with changes in the size of blood vessels.</p>



<p>These waves cause the blood vessels to alternately contract and expand in a steady rhythm. This rhythmic motion acts like a pump, pushing cerebrospinal fluid through the <a href="https://www.earth.com/news/deep-sleep-how-slow-waves-boost-memory-formation/" target="_blank" rel="noreferrer noopener">brain</a> to remove waste.</p>



<p>“You can view norepinephrine as this conductor of an orchestra. There’s a harmony in the constriction and dilation of the arteries, which then drives the cerebrospinal fluid through the brain to remove the waste products,” noted lead author Natalie Hauglund.</p>



<h2 class="wp-block-heading" id="h-are-all-types-of-sleep-equal">Are all types of sleep equal?</h2>



<p>The researchers investigated how zolpidem, a common sleep aid, affects the brain's cleaning system during deep sleep. They found that mice given zolpidem experienced a significant reduction in norepinephrine waves, which are essential for driving the brain’s waste-clearing process. </p>



<p>Specifically, the norepinephrine waves were 50% weaker in mice that were given zolpidem than in mice that slept naturally.</p>



<p>As a result, the fluid transport system responsible for flushing out brain waste slowed down by more than 30 percent. Although zolpidem helped the mice fall asleep faster, their brain’s ability to remove harmful waste was compromised.</p>



<p>This suggests that while sleep aids like zolpidem can promote sleep, they might interfere with the brain's natural cleaning processes, potentially <a href="https://www.earth.com/news/poor-sleep-habits-may-age-the-brain-faster/" target="_blank" rel="noreferrer noopener">affecting long-term brain health</a>.</p>



<p>“If people aren’t getting the full benefits of sleep, they should be aware of that so they can make informed decisions,” Hauglund warned.</p>



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



<p>While this study was focused on mice, the researchers believe the findings are relevant to humans, who also have a glymphatic system.</p>



<p>Similar patterns of norepinephrine waves, blood flow changes, and fluid dynamics have been observed in human brains. Disruptions to these processes may contribute to neurological conditions like Alzheimer’s disease.</p>



<p>“Now we know norepinephrine is driving the cleaning of the brain, we may figure out how to get people a long and restorative sleep,” Nedergaard concluded.</p>



<h2 class="wp-block-heading" id="h-keeping-the-brain-healthy-with-sleep">Keeping the brain healthy with sleep</h2>



<p>The research highlights how critical deep sleep is for keeping the brain healthy. During deep sleep, the brain’s cleaning system removes harmful waste and toxins. This process is essential for preventing neurological disorders and <a href="https://www.earth.com/news/sleep-is-essential-for-memory-formation/" target="_blank" rel="noreferrer noopener">maintaining cognitive function</a>.</p>



<p>While sleep aids can make falling asleep easier, they may interfere with the brain's natural cleaning process by disrupting mechanisms like norepinephrine waves, which drive waste clearance. </p>



<p>This disruption could reduce the benefits of sleep and potentially harm long-term brain health.</p>



<p>By understanding these processes, people can make more informed decisions about their sleep habits, such as prioritizing natural, restorative sleep over relying on sleep medications.</p>



<p>The study is published in the journal <a href="https://www.cell.com/cell/abstract/S0092-8674(24)01343-6" target="_blank" rel="noreferrer noopener"><em>Cell</em></a>.</p>

Deep sleep clears toxic waste from the brain

A good night’s sleep does more than help you feel...

<p>Scientists have long pondered how evolution resulted in the development of both herbivores and carnivores. To understand this, it is important to clarify what type of food did extinct vertebrates eat. But how can we know what the diets of these creatures were?&nbsp;</p>



<p>While in living animals we can directly observe what they feed on, in the case of extinct species researchers must rely on morphological or chemical information supplied by fossils.&nbsp;</p>



<p>Now, a research team led by professor Thomas Tütken from <a href="https://www.uni-mainz.de/en/" target="_blank" rel="noreferrer noopener">Johannes Gutenberg University Mainz</a> (JGU) has compiled a reference framework of isotope compositions for modern reptiles. This dataset stands to improve our ability to identify the diets of <a href="https://www.earth.com/news/study-reveals-secrets-of-the-evolution-of-prehistoric-reptiles/" target="_blank" rel="noreferrer noopener">ancient reptiles</a>, including dinosaurs.</p>



<p>“This reptile reference framework is a convenient toolbox that will enable us to better reconstruct the diet of extinct animals, such as dinosaurs,” Tütken explained. “A set of comparable data of this kind has not previously been available.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-diverse-diets-of-modern-reptiles">Diverse diets of modern reptiles </h2>



<p>Today's reptiles showcase a remarkable range of diets, from strictly plant-based to exclusively carnivorous. Many also exhibit specialized feeding preferences, such as the marine iguana in the Galapagos, which eats only algae, or chameleons, which subsist solely on insects.&nbsp;</p>



<p>Gila monsters prefer eggs, while top predators like the saltwater crocodile and the <a href="https://www.earth.com/news/komodo-dragons-have-iron-tipped-teeth-to-rip-apart-flesh/" target="_blank" rel="noreferrer noopener">Komodo dragon</a> feed entirely on meat. “This diversity makes it difficult to reconstruct the nutritional habits of extinct animals,” Tütken said.</p>



<p>The oldest known ancestors of modern reptiles lived more than 300 million years ago; for instance, the 315-million-year-old <em>Hylonomus</em> resembled a lizard. These early reptiles often bore skulls, jaws, and teeth indicative of insectivory.&nbsp;</p>



<p>The point in geological history when they transitioned from insect-eating to purely carnivorous or herbivorous diets remains unclear.</p>



<h2 class="wp-block-heading" id="h-building-a-geochemical-reference">Building a geochemical reference</h2>



<p>In creating their new framework, Tütken’s team examined 28 modern reptile species by measuring calcium and strontium isotopes in their bones and teeth, which offer chemical clues about what these animals eat.&nbsp;</p>



<p>“To obtain a wide spectrum for comparison, we selected reptiles with pronounced herbivorous or carnivorous behavior, and we also included those with specialized dietary preferences,” Tütken noted. The list included alligators, monitor lizards, chameleons, and more.</p>



<p>Focusing on calcium isotopes, the researchers highlighted the ratio of calcium-44 to calcium-42. They observed a clear trend in which these isotope concentrations decreased at every step in the food chain.&nbsp;</p>



<p>“Overall, the values are highest in insectivorous reptiles, clearly differentiating these from animals with other feeding behaviors,” said lead author Michael Weber, a paleontologist at JGU.&nbsp;</p>



<h2 class="wp-block-heading" id="h-detecting-unique-feeding-patterns-nbsp">Detecting unique feeding patterns&nbsp;</h2>



<p><a href="https://www.earth.com/news/forest-biodiversity-benefits-from-large-herbivores-like-elephants-and-moose/" target="_blank" rel="noreferrer noopener">Herbivores</a> showed lower isotope ratios, while carnivores presented the lowest levels. This approach even allowed them to detect unique feeding patterns, such as the algae diet of marine iguanas and the egg-based diet of other reptiles. The team also examined stable strontium-88 to strontium-86 ratios.&nbsp;</p>



<p>“We set up the first extensive reference system of stable strontium isotopes as a dietary proxy. The results for strontium are largely consistent with those for calcium isotopes in respect of the various nutritional forms,” explained study co-author and paleontologist Katrin Weber.&nbsp;</p>



<p>However, strontium is more vulnerable to alteration over time, making calcium isotopes the more reliable measure for extinct species.</p>



<h2 class="wp-block-heading" id="h-comparing-reptiles-to-mammals">Comparing reptiles to mammals</h2>



<p>In analyzing these isotopes, the researchers discovered that reptiles show greater calcium isotope variability than <a href="https://www.earth.com/news/how-mammals-have-evolved-over-66-million-years/" target="_blank" rel="noreferrer noopener">mammals</a>, even under similar dietary regimes.&nbsp;</p>



<p>This phenomenon is believed to stem from physiological differences, and it illustrates why mammal-based data cannot directly determine the diets of prehistoric reptiles such as dinosaurs.</p>



<h2 class="wp-block-heading" id="h-teeth-wear-patterns-and-animal-diets">Teeth wear patterns and animal diets</h2>



<p>Beyond chemical traces, the scientists also investigated the mechanical wear patterns on modern reptile teeth, collecting data in collaboration with Dr. Daniela Winkler at <a href="https://www.uni-kiel.de/en/" target="_blank" rel="noreferrer noopener">Kiel University</a>.&nbsp;</p>



<p>Scratches on tooth surfaces reveal whether an animal consumed tough materials such as shells or bones, or softer foods.&nbsp;</p>



<p>When combined with isotope data, these wear patterns can distinguish faunivores that ingested abrasive substances from those relying on soft food sources.</p>



<h2 class="wp-block-heading" id="h-discovering-the-diets-of-extinct-species">Discovering the diets of extinct species</h2>



<p>“In order to understand and interpret the data for chemical and mechanical patterns of nutritional behavior from fossil finds, we first had to determine the corresponding information for related modern species with their known dietary preferences,” said Tütken.</p>



<p>“As a result, we now have a reference frame for comparison that enables the precise diet assessment and thus a more accurate reconstruction of the feeding habits of extinct species.”</p>



<p>The study forms part of a larger initiative led by Tütken, who in 2016 received an ERC Consolidator Grant to examine the feeding habits of early land vertebrates.&nbsp;</p>



<p>By combining geochemical and mechanical evidence, Tütken’s team has created an essential resource for scientists to unravel the mystery of what ancient reptiles - and possibly <a href="https://www.earth.com/news/new-tracks-discovered-on-uks-dinosaur-highway/" target="_blank" rel="noreferrer noopener">dinosaurs</a> - might have eaten, guiding us toward a deeper understanding of evolutionary history.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1098/rspb.2024.2002" target="_blank" rel="noreferrer noopener"><em>Proceedings of the Royal Society B</em></a>.</p>

Reptiles provide new clues about the diets of extinct animals

Scientists have long pondered how evolution resulted in the development...

<p>Transformative life decisions, such as changing careers, moving across the world, or ending significant relationships, often redefine who we are and shape the paths we follow. </p>



<p>These decisions carry profound implications, and their outcomes are frequently unpredictable.&nbsp;</p>



<p>A new study by researchers at the <a href="https://www.mpib-berlin.mpg.de/en" target="_blank" rel="noreferrer noopener">Max Planck Institute for Human Development</a> introduces a novel framework for studying and understanding these critical life choices.</p>



<h2 class="wp-block-heading" id="h-moving-beyond-simplified-models">Moving beyond simplified models</h2>



<p>“Understanding life's biggest decisions requires going beyond the oversimplified models often used in the behavioral sciences,” said lead author Shahar Hechtlinger.&nbsp;</p>



<p>She emphasized that traditional research on <a href="https://www.earth.com/news/optimal-decision-making-is-a-balance-of-experience-and-knowledge/" target="_blank" rel="noreferrer noopener">decision-making</a> often relies on overly simplified scenarios, which fail to capture the complexity of real-life transformative decisions.&nbsp;</p>



<p>“In research on judgment and decision-making, we often rely on highly simplified, stylized tasks. However, these controlled scenarios are in stark contrast to the consequential decisions that people face in real life across cultures and contexts,” Hechtlinger explained.&nbsp;</p>



<p>The researchers advocate for examining these choices in their natural context, accounting for cultural and emotional dimensions that are often overlooked.</p>



<h2 class="wp-block-heading" id="h-key-dimensions-of-transformative-decisions">Key dimensions of transformative decisions</h2>



<p>Using a text-based analysis of personal stories, online discussions, books, and other narratives, the researchers identified five core dimensions that define transformative decisions.&nbsp;</p>



<p>Each dimension reflects unique challenges and uncertainties inherent in life-altering choices:</p>



<h3 class="wp-block-heading" id="h-conflicting-cues">Conflicting cues</h3>



<p>Competing <a href="https://www.earth.com/news/peoples-moral-values-literally-change-with-the-weather/" target="_blank" rel="noreferrer noopener">values</a> often complicate transformative choices. For instance, immigrating to another country might promise safety but at the cost of leaving loved ones behind.</p>



<h3 class="wp-block-heading" id="h-change-of-self">Change of self</h3>



<p>Transformative decisions can profoundly reshape personal identity and values. Becoming a parent or leaving a long-term relationship can result in both desired and undesired changes in self-perception.</p>



<h3 class="wp-block-heading" id="h-uncertain-experiential-value">Uncertain experiential value</h3>



<p>The outcomes of transformative choices are often unpredictable. For example, switching careers may spark doubts about whether the new path will lead to satisfaction or regret.</p>



<h3 class="wp-block-heading" id="h-daunting-change">Daunting change</h3>



<p>Many transformative decisions, such as <a href="https://www.earth.com/news/ancient-dna-reveals-human-migration-patterns-in-first-millennium-ad/" target="_blank" rel="noreferrer noopener">migration</a> or divorce, carry a sense of permanence, making them daunting to undertake.</p>



<h3 class="wp-block-heading" id="h-risk-vs-rewards">Risk vs. rewards</h3>



<p>These choices are often accompanied by significant emotional, financial, or social risks, alongside the potential for rewards.</p>



<h2 class="wp-block-heading" id="h-strategies-for-navigating-transformative-decisions">Strategies for navigating transformative decisions</h2>



<p>The researchers proposed several strategies to help individuals make better decisions when faced with transformative choices.&nbsp;</p>



<p>These approaches are grounded in psychological principles and tailored to address the five identified dimensions:</p>



<h3 class="wp-block-heading" id="h-tallying-heuristic-nbsp"><strong>Tallying heuristic</strong>&nbsp;</h3>



<p>When values conflict, this method simplifies comparisons by counting the positive and negative reasons for each option without weighing their importance.</p>



<h3 class="wp-block-heading" id="h-ideal-self-realization-nbsp"><strong>Ideal self-realization</strong>&nbsp;</h3>



<p>This strategy aligns decisions with one’s vision of their ideal self, helping individuals make choices that resonate with their long-term identity goals.</p>



<h3 class="wp-block-heading" id="h-learning-from-others-nbsp"><strong>Learning from others</strong>&nbsp;</h3>



<p>Observing people who have faced similar decisions can provide valuable insights into potential outcomes, reducing uncertainty.</p>



<h3 class="wp-block-heading" id="h-testing-the-waters-nbsp"><strong>Testing the waters</strong>&nbsp;</h3>



<p>For irreversible decisions, taking small, reversible steps - such as renting before committing to a permanent move - can help mitigate risks.</p>



<h3 class="wp-block-heading" id="h-hedge-clipping-nbsp"><strong>Hedge clipping</strong>&nbsp;</h3>



<p>Incremental actions that minimize harm, such as securing financial stability before making a risky choice, offer a safety net during transitions.</p>



<h2 class="wp-block-heading" id="h-expanding-the-theory-of-ecological-rationality">Expanding the theory of ecological rationality</h2>



<p>The framework significantly contributes to ecological rationality, a theory that examines how decision-making strategies succeed when adapted to specific environments.&nbsp;</p>



<p>“Ecological rationality emphasizes the importance of a fit between decision strategies, environments, and individuals,” explains Ralph Hertwig, co-author and director of the Center for Adaptive Rationality at Max Planck.&nbsp;</p>



<p>This research broadens the theory by integrating subjective dimensions, such as personal identity and evolving values, into decision-making processes.&nbsp;</p>



<p>The framework highlights how external constraints, individual aspirations, and decision strategies interact, offering a richer understanding of how people navigate transformative life choices.</p>



<h2 class="wp-block-heading" id="h-understanding-transformative-life-decisions-nbsp">Understanding transformative life decisions&nbsp;</h2>



<p>The framework's implications extend beyond personal decision-making. It provides valuable tools for policymakers, therapists, and organizations supporting individuals through life transitions.&nbsp;</p>



<p>For example, migration policies could incorporate strategies to address risks and irreversibility, while therapists might use the framework to guide clients through significant personal changes.&nbsp;</p>



<p>By understanding the dimensions of transformative decisions, these stakeholders can design programs and interventions tailored to the complexities of such choices.</p>

Navigating uncertainty: How to make transformative life decisions

Transformative life decisions, such as changing careers, moving across the...

<p>When we think of airport neighborhoods, we often imagine the hustle and bustle and the constant sounds of take-offs and landings. However, a recent study led by researchers at the University College London (UCL) highlights an unseen, alarming health risk to those living in such areas: a heightened chance of heart problems.</p>



<p>The study reveals a concerning link between high aircraft noise exposure and poor heart function, increased risks of heart attacks and strokes, and life-threatening heart rhythms.</p>



<h2 class="wp-block-heading" id="h-heart-health-after-living-near-airports">Heart health after living near airports</h2>



<p>The researchers examined 3,635 individuals who resided near major airports in England - specifically Heathrow, Gatwick, Birmingham, and Manchester.</p>



<p>The goal was to assess whether people living in areas with higher aircraft noise levels have decreased heart health compared to those who live in <a href="https://www.earth.com/news/green-environments-and-sidewalks-improve-heart-health/" target="_blank" rel="noreferrer noopener">quieter neighborhoods</a>.</p>



<p>Focusing on heart imaging data, the researchers found a significant association between exposure to higher levels of noise from airports and changes in heart structure and function.</p>



<p>Individuals exposed to more aircraft noise had heart muscles that were less flexible and thicker. These changes make the heart less effective at contracting and expanding, which impairs its ability to pump blood efficiently.</p>



<p>Furthermore, the observed structural changes in the heart translated into reduced overall efficiency in circulating blood throughout the body.</p>



<h2 class="wp-block-heading" id="h-aircraft-noise-at-night">Aircraft noise at night</h2>



<p>The study highlighted that&nbsp;night-time aircraft noise&nbsp;had an even more pronounced impact. This could be due to disruptions in sleep, which is crucial for maintaining heart health, as well as the likelihood of longer exposure during nighttime when people are typically at home.</p>



<p>“Our study is observational so we cannot say with certainty that high levels of aircraft noise caused these differences in heart structure and function," explained senior author Dr. Gaby Captur.</p>



<p>"However, our findings add to a growing body of evidence that aircraft noise can adversely affect heart health." </p>



<h2 class="wp-block-heading" id="h-broader-impact-of-aircraft-noise">Broader impact of aircraft noise </h2>



<p>Noise pollution can trigger stress responses and over-activate the sympathetic nervous system, leading to elevated blood pressure and the release of stress hormones like cortisol. These factors can contribute to <a href="https://www.earth.com/news/heart-disease-patients-have-a-unique-vulnerability-to-air-pollution/" target="_blank" rel="noreferrer noopener">heart abnormalities</a>, inflammation, and atherosclerosis.</p>



<p>“Aircraft noise at night has been shown to affect sleep quality, and this may be an important factor affecting health,” added Professor Anna Hansell of the <a href="https://le.ac.uk" target="_blank" rel="noreferrer noopener">University of Leicester</a>.</p>



<p>The experts estimate that individuals with heart abnormalities linked to aircraft noise may face up to four times the risk of major cardiac events.</p>



<h2 class="wp-block-heading" id="h-mitigating-exposure-to-aircraft-noise">Mitigating exposure to aircraft noise </h2>



<p>The study’s findings emphasize the critical need for action by both government and industry to mitigate aircraft noise exposure, particularly for protecting the heart health of communities near airports. </p>



<p>High noise levels are not just a nuisance but a potential public health risk, with direct links to cardiovascular problems.</p>



<p>Dr. Cristian Topriceanu, the study’s first author, explained that noise exposure can trigger various health issues that, in turn, impact heart health. </p>



<ul class="wp-block-list">
<li><strong>Increased BMI (Body Mass Index):</strong> Noise-related stress and disrupted sleep can contribute to weight gain, a significant <a href="https://www.earth.com/news/climate-change-worsens-cardiovascular-health-risks/" target="_blank" rel="noreferrer noopener">risk factor for heart disease</a>.</li>



<li><strong>Higher blood pressure:</strong> Prolonged noise exposure can activate stress responses, raising blood pressure and straining the heart.</li>
</ul>



<h2 class="wp-block-heading" id="h-protecting-heart-health-near-airports">Protecting heart health near airports</h2>



<p>Given these risks, Professor Anna Hansell stressed the importance of adopting lifestyle measures to protect heart health, regardless of noise exposure. She recommended the following preventive strategies</p>



<ul class="wp-block-list">
<li><strong>A balanced diet:</strong>&nbsp;<a href="https://www.earth.com/news/how-fruits-and-vegetables-improve-heart-health/" target="_blank" rel="noreferrer noopener">Eating nutrient-rich foods</a> supports overall cardiovascular health.</li>



<li><strong>Regular physical activity:</strong>&nbsp;Exercise strengthens the heart and helps maintain a healthy weight.</li>



<li><strong>Managing chronic conditions:</strong>&nbsp;Keeping conditions like diabetes and high blood pressure under control minimizes strain on the heart.</li>
</ul>



<p>These measures not only reduce the risk of heart disease but also build resilience against stressors like environmental noise. </p>



<p>While individual efforts are vital, the study calls for systemic interventions to address the root causes of noise pollution and its health impacts.</p>



<h2 class="wp-block-heading" id="h-damaging-impact-of-noise-pollution">Damaging impact of noise pollution </h2>



<p>“This innovative study reveals the potential invisible impact for those living close to some of our biggest travel hubs," said Professor James Leiper from the <a href="https://www.bhf.org.uk" target="_blank" rel="noreferrer noopener">British Heart Foundation</a>.</p>



<p>"While observational studies like this can’t prove cause and effect, these findings add to previous research showing the damaging impact of noise pollution on our <a href="https://www.earth.com/news/heart-healthy-habits-can-reverse-your-biological-age/" target="_blank" rel="noreferrer noopener">heart health</a>."</p>



<p>The study highlights the need for further research and immediate action to address noise pollution. For those living near airports, understanding these risks is the first step toward safeguarding long-term heart health.</p>



<p>The study is published in the<em> <a href="https://www.sciencedirect.com/science/article/pii/S0735109724097973?via%3Dihub" target="_blank" rel="noreferrer noopener">Journal of the American College of Cardiology</a>. </em></p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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

<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>"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>
