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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

<p>In the quest for better water conservation planning along the <a href="https://www.earth.com/news/biden-administration-proposes-water-rationing-to-save-the-colorado-river/" target="_blank" rel="noreferrer noopener">Colorado River</a>, researchers have turned their focus to the role of mountains in shaping the impact of El Niño and La Niña on precipitation in western North America. </p>



<p>This new study emerges amid a transition from a strong La Niña to a potent El Niño, aiming to enhance the precision of winter precipitation predictions in the intermountain West.</p>



<h2 class="wp-block-heading" id="h-studying-mountains-and-el-nino">Studying mountains and El Niño</h2>



<p>The research team, led by James Stagge, an assistant professor at <a href="https://www.osu.edu/" target="_blank" rel="noreferrer noopener">The Ohio State University</a>, delved into 150 years of rain and snow data and its correlation with historic El Niño-Southern Oscillation (<a href="https://www.earth.com/news/satellite-detects-early-warning-signs-of-an-el-nino-event/" target="_blank" rel="noreferrer noopener">ENSO</a>) patterns. </p>



<p>Their findings reveal a trend of increasing winter precipitation in the north and a decrease in the south, particularly during the late 20th century. The study highlights how mountains amplify or obstruct precipitation, causing heavier rainfall on their western flanks and reduced precipitation eastward.</p>



<p>Stagge emphasizes the significance of accurate winter precipitation forecasts for managing water resources in one of the world's most water-stressed regions. </p>



<p>He points out, “If you can predict how much precipitation you’ll have in the winter, you’ll have a good sense of what your summer dry period will look like in terms of your water allocation.” Improved predictions enable better preparation for droughts and conservation measures.</p>



<h2 class="wp-block-heading" id="h-el-nino-southern-oscillation-enso">El Niño Southern Oscillation (ENSO)</h2>



<p>ENSO, encompassing <a href="https://www.earth.com/news/forecasters-warn-of-weather-chaos-as-el-nino-arrives-early/" target="_blank" rel="noreferrer noopener">El Niño</a> and La Niña, relates to temperature anomalies in the Pacific Ocean and significantly influences global weather patterns. In this study, the focus was on the intermountain West, a region historically overlooked in ENSO studies. Researchers used water gauge readings from 1871 and linked them to ENSO trends recorded by the NOAA's <a href="https://psl.noaa.gov/enso/mei/" target="_blank" rel="noreferrer noopener">Multivariate ENSO Index</a>.</p>



<p>Stagge’s team prioritized observational data over climate models, seeking a closer alignment with reality. They scrutinized the specifics of precipitation changes during El Niño and La Niña years at different elevations and locations. </p>



<p>This approach revealed nuanced historic patterns, especially in the northern intermountain region, where elevation variations complicate the tracking of ENSO's effects on winter precipitation.</p>



<h2 class="wp-block-heading" id="h-orographic-effect-and-regional-variations">Orographic effect and regional variations</h2>



<p>The study underscores the orographic effect, where moist Pacific air ascends over mountains, releasing precipitation, and leaving drier air on the eastern side. This phenomenon, combined with ENSO, results in significant precipitation disparities. The research also noted a dipole effect, with opposing precipitation responses in the north and south during ENSO phases.</p>



<p>The findings suggest that ENSO forecasts are more indicative in the north, while quantitative temperature change estimates might be more beneficial in the south. This disparity is attributed to the varying topography and its influence on air flow and precipitation.</p>



<p>In summary, Stagge’s study offers a valuable tool for water managers and stakeholders in western North America. By enhancing the understanding and prediction of precipitation patterns, it paves the way for more effective water shortage preparation and conservation strategies. </p>



<p>The integration of this research with NOAA's data and modeling tools could further refine short-term forecasts, offering a boon to the region's water-dependent economy and large cities.</p>

<p>The <a href="https://www.un.org/en/" target="_blank" rel="noreferrer noopener">United Nations</a> (UN) has released a critical report which signals an "unprecedented emergency on a planetary scale" due to human-induced <a href="https://www.earth.com/news/climate-change-has-made-droughts-20-times-more-likely/">droughts</a>. </p>



<p>The Global Drought Snapshot, launched at <a href="https://www.cop28.com/en/" target="_blank" rel="noreferrer noopener">COP28</a> climate talks in the UAE, is a comprehensive analysis of recent drought data over the past two years, emphasizing the escalating crisis of drought worldwide.</p>



<p>The analysis was led by the UN Convention to Combat Desertification (UNCCD), established at the 1992 Earth Summit, along with the UNFCCC and UN CBD.</p>



<h2 class="wp-block-heading" id="h-silent-devastation-nbsp">Silent devastation&nbsp;</h2>



<p>“Unlike other disasters that attract media attention, droughts happen silently, often going unnoticed and failing to provoke an immediate public and political response," said UNCCD Executive Secretary Ibrahim Thiaw.</p>



<p>"This silent devastation perpetuates a cycle of neglect, leaving affected populations to bear the burden in isolation."&nbsp;</p>



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



<p>In China, 15–20 percent of the population faces more frequent moderate-to-severe droughts, with drought intensity expected to increase by 80 percent by 2100.</p>



<p>The Horn of Africa has 23 million people severely food insecure, attributed to drought.</p>



<p>The United States experienced severe drought across five percent of its contiguous states in May 2023. The La Plata basin in Brazil–Argentina faced its worst drought in 78 years in 2022, impacting global crop markets.</p>



<p>Europe was hit by its worst drought in 500 years in 2022, affecting an area almost four times the average since 2000.</p>



<h2 class="wp-block-heading" id="h-agriculture-and-forests">Agriculture and forests</h2>



<p>The report also touches on the severe impact of drought on agriculture and forests, including 70 percent damage to cereal crops in the Mediterranean from 2016–2018.</p>



<p>Consecutive rainfall season failures in the Horn of Africa caused the region’s worst drought in 40 years (with Ethiopia, Kenya and Somalia particularly hard hit), contributing to reduced agricultural productivity, food insecurity and high food prices.</p>



<p>There have also been significant losses in grazing land and an expected increase in forest losses in various regions.</p>



<h2 class="wp-block-heading" id="h-water-conditions">Water conditions</h2>



<p>California's Central Valley is facing accelerated groundwater decline and water-quality degradation.</p>



<p>The Rhine and Yangtze rivers experienced drastic reductions in water levels, impacting shipping and affecting millions.&nbsp;</p>



<p>In southern China, five million people have been affected by record-low water levels in the Yangtze River due to drought and prolonged heat.</p>



<p>On the Mississippi River, a backlog of barges in late 2022 due to low water levels caused $20 billion in supply chain disruptions and other economic damage.&nbsp;&nbsp;</p>



<h2 class="wp-block-heading" id="h-social-dimensions-nbsp">Social dimensions&nbsp;</h2>



<p>The social dimensions are equally concerning, with 85 percent of people affected by droughts living in low- or middle-income countries.</p>



<p>Furthermore, the likelihood of being killed by floods, droughts and storms is 15 times greater in the highly vulnerable regions.&nbsp;</p>



<h2 class="wp-block-heading" id="h-call-to-action">Call to action</h2>



<p>The Global Drought Snapshot concludes with a call to action, urging for binding global agreements and proactive measures to mitigate drought impacts.&nbsp;</p>



<p>The report emphasizes the need for nature-based solutions to offset CO2 emissions and agricultural practices that adopt water-efficient technologies.</p>



<p>The experts also stress the importance of respecting the planet's boundaries and ensuring the sustainability of natural hydrological cycles.</p>



<h2 class="wp-block-heading" id="h-wake-up-call-nbsp">Wake-up call&nbsp;</h2>



<p>“The Global Drought Snapshot report speaks volumes about the urgency of this crisis and building global resilience to it," said Thiaw.</p>



<p>"With the frequency and severity of drought events increasing, as reservoir levels dwindle and crop yields decline, as we continue to lose biological diversity and famines spread, transformational change is needed.”&nbsp;</p>



<p>“We hope this publication serves as a wake-up call.”</p>

Global drought crisis: UN warns of unprecedented emergency

The United Nations (UN) has released a critical report which...

<p>A staggering event on October 4-5 in Chicago led to the demise of nearly 1,000 <a href="https://www.earth.com/news/window-collisions-are-a-leading-cause-of-bird-mortality/">birds</a>, as they crashed into a brightly lit glass structure. While such extensive bird fatalities are uncommon, artificial light remains a significant and escalating hazard to migratory birds.</p>



<p>In a comprehensive study published in <a href="http://dx.doi.org/10.1038/s41467-023-43046-z" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a>, researchers employed weather radar data to chart bird stopover densities across the U.S. The study revealed that artificial light is a prime factor influencing where birds land during migration.&nbsp;</p>



<h2 class="wp-block-heading" id="h-birds-face-multiple-challenges-nbsp">Birds face multiple challenges&nbsp;</h2>



<p>Kyle Horton, an assistant professor at <a href="https://www.colostate.edu/" target="_blank" rel="noreferrer noopener">Colorado State University</a>’s Department of Fish, Wildlife and Conservation Biology and the study’s lead author, explained that city lights can entice birds into hazardous urban environments.</p>



<p>The challenges for migrating birds in urban areas are manifold, including dangerous building collisions, habitat loss, limited food availability, and threats from humans and predators like cats. Urban parks offer some respite, but they come with their own set of challenges, such as competition for scarce resources.</p>



<h2 class="wp-block-heading" id="h-migration-stopover-hotspots">Migration stopover hotspots</h2>



<p>Migration is fraught with peril for birds, involving extensive travel that can deplete up to half of their body mass. “These stopover locations are the fueling stations,” Horton said. “If they don’t have a good spot to rebuild energy supplies, migration can’t happen."</p>



<p>This study marks the first time migration stopover hotspots across the contiguous United States have been mapped on such a large scale. Understanding these patterns can aid in developing conservation strategies.</p>



<p>“Cities pose multiple risks to migrating birds,” explained co-author and <a href="https://msu.edu/">Michigan State University</a> Professor Geoff Henebry. “They also offer resources for the tired birds to rest and refuel."&nbsp;</p>



<p>"Our study is notable in that it combines big data – and a lot of processing – from the weather surveillance radar network with big data from multiple spaceborne sensors to address key questions regarding the influence of urban areas on bird migration.”</p>



<h2 class="wp-block-heading" id="h-helping-birds-survive-artificial-light">Helping birds survive artificial light</h2>



<p>However, the attraction of birds to cities raises a conservation dilemma: should urban areas be preserved as vital stopover sites, or should efforts be concentrated on reducing urban lighting? Horton is collaborating with various organizations to tackle both issues, but the multifaceted nature of urban lighting presents complexities.</p>



<p>Light pollution not only affects birds but also disrupts human circadian rhythms, contributing to several health issues. “We don’t often think about light as a pollutant, but it checks all the boxes of what pollution is,” Horton said.</p>



<h2 class="wp-block-heading" id="h-migration-forecasts-nbsp">Migration forecasts&nbsp;</h2>



<p>Initiatives like <a href="https://birdcast.info/">BirdCast</a> offer migration forecasts and real-time maps, enabling individuals and cities to minimize artificial light on critical migration nights. Simple measures, such as retrofitting windows with decals and adjusting light brightness and color, can significantly reduce bird collisions.</p>



<p>The tragic incident at Chicago’s McCormick Place Convention Center is a stark reminder of the dangers of light pollution. Public awareness and simple actions, like turning off unnecessary lights, can have an immediate and beneficial impact on bird safety.&nbsp;</p>



<p>“If we turned off all lights tonight, there would be no birds colliding because of lights tonight,” Horton concluded.</p>

Artificial light is luring birds to their deaths around the world by the millions

A staggering event on October 4-5 in Chicago led to...

<p>In the breathtaking Himalayan mountains, an extraordinary phenomenon is unfolding. Researchers have found that Himalayan <a href="https://www.earth.com/news/melting-arctic-glaciers-are-releasing-a-new-source-of-potent-methane-emissions/">glaciers</a> have a remarkable response to global warming.&nbsp;</p>



<p>Contrary to the expectation of rapid melting, these glaciers are exhibiting a unique self-preserving mechanism by cooling the air around them, leading to the generation of cold winds.&nbsp;</p>



<h2 class="wp-block-heading" id="h-counteracting-climate-change-nbsp">Counteracting climate change&nbsp;</h2>



<p>This phenomenon, observed across the Himalayan range, raises intriguing questions about the glaciers' longevity in counteracting the effects of climate change.</p>



<p>The study was conducted by a team of international researchers led by Professor Francesca Pellicciotti of the <a href="https://ista.ac.at/" target="_blank" rel="noreferrer noopener">Institute of Science and Technology Austria</a> (ISTA). The findings reveal how these glaciers are paradoxically generating cold winds to combat rising temperatures.</p>



<h2 class="wp-block-heading" id="h-puzzling-observation-nbsp">Puzzling observation&nbsp;</h2>



<p>The Pyramid International Laboratory/Observatory climate station is located on the southern slopes of Mount Everest alongside the Khumbu and Lobuche glaciers. The station has continuously recorded hourly meteorological data for nearly three decades.</p>



<p>According to this data, temperatures near the glaciers have remained stable despite global warming. This puzzling observation led to the discovery that, while minimum temperatures rose, the maximum surface temperatures in summer were decreasing.&nbsp;</p>



<h2 class="wp-block-heading" id="h-key-insights">Key insights</h2>



<p>According to Professor Pellicciotti and her colleagues, including Franco Salerno and Nicolas Guyennon of the National Research Council of Italy, this pattern results from the glaciers' increased temperature exchange with the air.&nbsp;</p>



<p>“We found that the overall temperature averages seemed stable for a simple reason. While the minimum temperatures have been steadily on the rise, the surface temperature maxima in summer were consistently dropping,” said Salerno.&nbsp;</p>



<p>The glaciers are reacting to the warming climate by increasing their temperature exchange with the surface, explained Pellicciotti. She noted that global warming causes an increased temperature difference between the warmer environmental air over the glacier and the air mass in direct contact with the glacier's surface.&nbsp;</p>



<p>“This leads to an increase in turbulent heat exchange at the glacier’s surface and stronger cooling of the surface air mass,” said Pellicciotti.&nbsp;</p>



<h2 class="wp-block-heading" id="h-cooling-their-surroundings">Cooling their surroundings</h2>



<p>The colder, denser air masses that are generated flow down the slopes, potentially cooling the lower parts of the glaciers and their surrounding ecosystems.</p>



<p>This counterintuitive response of the glaciers to warming was further supported by data from the ERA5-Land global climate and weather reanalysis. This tool, which combines model data with global observations, confirmed that such katabatic wind phenomena were not limited to Mount Everest but prevalent across the Himalayan range.&nbsp;</p>



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



<p>The team's future research aims to identify specific glacier characteristics that enable this reaction and to determine which glaciers might sustain such responses.</p>



<p>Intriguingly, the team plans to extend their research to the glaciers in the Pamir and Karakoram mountains, where the topography differs significantly from the Himalayas. This could provide crucial insights into whether these glaciers also generate cold winds and if so, whether these winds contribute more to cooling the glaciers themselves rather than their surrounding environments.</p>



<h2 class="wp-block-heading" id="h-emergency-reaction-nbsp">Emergency reaction&nbsp;</h2>



<p>The study also delves into the critical balance of accumulation and ablation in these glaciers. While they gain mass from the Indian subcontinent's summer monsoons, they lose it through melting.&nbsp;</p>



<p>The katabatic winds may be altering this balance by lowering the altitude at which precipitation occurs, potentially threatening the glaciers' mass input. Although it is a response to global warming, the phenomenon may not indicate long-term stability but rather an emergency reaction to the rising temperatures.</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>Ultimately, this means that these Himalayan glaciers may be approaching their preservation tipping point in some places, "but we do not know where and how,” said Pellicciotti. </p>

Himalayan glaciers are cooling the air around them to survive global warming

In the breathtaking Himalayan mountains, an extraordinary phenomenon is unfolding....

<p>The results of a study led by <a href="https://www.ucl.ac.uk/" target="_blank" rel="noreferrer noopener">University College London</a> (UCL) are challenging long-standing beliefs about the development of human brains in <a href="https://www.earth.com/news/babies-are-born-with-the-ability-to-recognize-the-beat-in-music/">newborns</a> compared to other primates.&nbsp;</p>



<p>According to the research, the idea that human newborns have underdeveloped brains is a misconception. The experts found that the brains of newborns are at a development level typical for primates.</p>



<h2 class="wp-block-heading" id="h-false-impression">False impression</h2>



<p>Human brains grow so much larger and more complex than other species after birth. This creates a false impression that newborns are underdeveloped, or “altricial.”</p>



<p>“This new work changes the overall understanding around the evolution of human brain development," said study lead author Dr. Aida Gomez-Robles.</p>



<p>"Humans seem so much more helpless when they’re young compared to other primates not because their brains are comparatively underdeveloped but because they still have much further to go.”</p>



<h2 class="wp-block-heading" id="h-human-brain-development-nbsp">Human brain development&nbsp;</h2>



<p>The research modifies the conventional view that human brains are less developed at birth due to evolutionary compromises, such as the need for babies’ heads to fit through the birth canal.</p>



<p>Traditionally, scientists have assessed brain development across species by comparing brain sizes at birth with adult brain sizes. This suggested that humans are born with a smaller percentage of their adult brain size compared to other primates, leading to the belief in their relative underdevelopment.&nbsp;</p>



<p>However, the UCL study indicates that other measures of human brain development align closely with other primates like chimpanzees, bonobos, gorillas, and orangutans.</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>The study also addresses the implications of these findings for the concept of brain plasticity in human evolution. It has been suggested that the perceived underdevelopment at birth results in greater brain malleability and sensitivity to environmental stimuli during early life, contributing to human intelligence.&nbsp;</p>



<p>The researchers clarify that while human brains do take longer to reach full capacity, this does not stem from significant underdevelopment at birth. Thus, while brain plasticity remains critical in human evolution, it is unlikely to be a result of being less developed at birth than other primates.</p>



<h2 class="wp-block-heading" id="h-how-the-research-was-conducted">How the research was conducted</h2>



<p>To conduct this analysis, the team examined the brain development of 140 different mammal species, including modern primates, rodents, carnivores, and the fossils of early humans and ancestral hominins.&nbsp;</p>



<p>The researchers compared fetal gestation lengths, the relative size of newborn brains and bodies to adult sizes, and overall brain size at birth and adulthood across these species.&nbsp;</p>



<p>The findings revealed that while there are considerable variations in brain development at birth among different mammal species, primates, including humans, show a consistent pattern of development.</p>



<p>This research, supported by the <a href="https://www.nsf.gov/" target="_blank" rel="noreferrer noopener">National Science Foundation</a> and the National Institutes of Health in the US, marks a significant shift in the understanding of human brain development and its evolutionary trajectory, challenging long-held assumptions in the field of anthropology and neurology.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1038/s41559-023-02253-z" target="_blank" rel="noreferrer noopener"><em>Nature Ecology &amp; Evolution</em></a>.</p>

Human brain development aligns closely with other primates

The results of a study led by University College London...

<p>In a concerning revelation, experts predict that global <a href="https://www.earth.com/news/epa-plans-to-eliminate-greenhouse-gas-emissions-from-power-plants-by-2040/">emissions</a> of carbon dioxide are on track to rise by approximately one percent, setting a new record in 2023.&nbsp;</p>



<p>This alarming insight is the conclusion of a preliminary study led by Glen Peters, an expert in the <a href="https://cicero.oslo.no/en">Centre for International Climate Research</a> (CICERO) in Norway.</p>



<p>With the impending threat of catastrophic climate impacts, experts contend that carbon emissions need to be slashed almost by half within this decade in order to meet global targets. These goals are geared towards curbing global warming and preventing dire consequences for the environment.</p>



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



<p>Carbon dioxide pollution is a primary contributor to the greenhouse effect, the process through which heat is trapped near Earth's surface, which leads to global warming.&nbsp;</p>



<p>When human activities (such as burning fossil fuels) release CO2 emissions, these gases trap heat from the sun's rays inside the atmosphere.&nbsp;</p>



<p>The trapped heat drives an increase in global temperatures, which triggers a cascade of impacts that are not yet fully understood. Some of the initial consequences include melting ice caps and glaciers, more frequent and severe weather events, changing precipitation patterns, and rising sea levels.&nbsp;</p>



<h2 class="wp-block-heading" id="h-rising-emissions">Rising emissions</h2>



<p>While Peters suggests that the best scenario would be a decline in global CO2 emissions by five percent this year, his study paints a starkly different picture. According to the research, instead of witnessing a decline, the most likely scenario for 2023 is an increase in emissions ranging from 0.5 percent to 1.5 percent.&nbsp;</p>



<p>The current trajectory of rising emissions poses a massive challenge to the objectives outlined in the Paris Agreement. This international treaty aims to restrict global warming to 1.5 degrees Celsius above pre-industrial levels.&nbsp;</p>



<p>Exceeding the target limit could trigger global climate tipping points, a possible outcome that is cause for grave concern. "Each year that emissions keep rising makes it all the harder to reach pathways consistent with Paris," said Peters.</p>



<h2 class="wp-block-heading" id="h-cop28">COP28</h2>



<p>The final analysis will be published in December, as world leaders meet in the United Arab Emirates for the UN climate change conference (COP28).</p>



<p>Of the four paradigm shifts that will be prioritized at COP28, the first is slashing emissions by 2030. Sultan Ahmed Al Jaber, Minister of Industry and Advanced Technology and UAE Special Envoy for Climate Change, has been appointed to serve as COP 28 the President-Designate.</p>



<h2 class="wp-block-heading" id="h-energy-transition-nbsp">Energy transition&nbsp;</h2>



<p>In a <a href="https://www.cop28.com/en/letter-to-parties">letter</a> to colleagues, Al Jaber states: "The world must urgently accelerate the energy transition in an orderly, just and equitable way that accounts for energy security and ensures that finance and technology is available for developing countries to implement the transition."&nbsp;</p>



<p>"All countries will need to act, all elements of the energy system will need to be addressed, and we must have an honest conversation about what it will take to deliver a responsible and just transition that empowers climate-positive development everywhere, in particular across the Global South."</p>



<h2 class="wp-block-heading" id="h-investments-in-fossil-fuels">Investments in fossil fuels</h2>



<p>Earlier in the year, the International Energy Agency (IEA) reported an expected peak in global demand for fossil fuels such as oil, gas, and coal within this decade. This forecast was attributed to the exponential growth in cleaner energy technologies and the rise of electric cars.&nbsp;</p>



<p>However, the IEA also raised concerns regarding increased investments in fossil fuels and persistently high emissions, especially in the backdrop of the post-pandemic economic surge and the energy crisis precipitated by Russia's invasion of Ukraine.</p>



<h2 class="wp-block-heading" id="h-lack-of-progress-nbsp">Lack of progress&nbsp;</h2>



<p>Peters commented on the lack of significant progress in transitioning to clean energy. He recalled that scientists were optimistic in 2015, hoping that emission levels might peak.&nbsp;</p>



<p>"Yet, here we are again, with a new peak in 2022, and yet another peak expected again in 2023," said Peters. "My concern is that we are doing half the job, growing clean energy, and not doing the other half of the job, transitioning away from fossil fuels."</p>



<p>The Global Carbon Budget report for 2023 will be published in December. It will reveal CO2 emissions from all sources, with calculations based on data from IEA reports.</p>

<p>Polar bears, the majestic icons of the Arctic, are elusive and vulnerable, making their conservation a challenging task. However, a breakthrough in DNA analysis using skin cells shed in their footprints offers new hope for monitoring these endangered species.</p>



<p>This innovative method, developed by a team of international scientists, promises a less invasive and more efficient way to gather essential data on <a href="https://www.earth.com/news/study-confirms-direct-link-between-polar-bear-survival-and-harmful-emissions/" target="_blank" rel="noreferrer noopener">polar bear populations</a>.</p>



<h2 class="wp-block-heading" id="h-monitoring-polar-bears-with-footprint-dna">Monitoring polar bears with footprint DNA</h2>



<p>Dr. Melanie Lancaster of the World Wide Fund for Nature <a href="https://www.arcticwwf.org/" target="_blank" rel="noreferrer noopener">Global Arctic Programme</a> is the senior author of the study. “It is particularly challenging, expensive, and time-consuming to find polar bears in the Arctic, let alone count them and understand how they are coping with climate change,” said Lancaster.</p>



<p>The difficulties in locating and counting these bears, combined with the need to understand their response to climate change, has left a gap in critical data regarding their population size and connectivity.</p>



<p>Inspired by forensic techniques suited for tiny, degraded DNA samples, the scientists developed a method that avoids the physical capture of bears. This method avoids an often stressful and dangerous situation for both the animals and humans. Elisabeth Kruger of the <a href="https://www.worldwildlife.org/" target="_blank" rel="noreferrer noopener">World Wildlife Fund</a>, another author of the article, highlights the significance of this method. </p>



<p>“Many Inuit express concern about invasive research methods,” said Kruger. “People are concerned about the welfare of the individual <a href="https://www.earth.com/news/scientists-unravel-the-secrets-of-polar-bear-fur/" target="_blank" rel="noreferrer noopener">polar bear</a> and the health and safety of people who may harvest the bear later. This is one of the reasons we are so excited about new methods like this - the person collecting the sample never needs to even see or be seen by the polar bear.”</p>



<h2 class="wp-block-heading" id="h-edna-from-animal-tracks">eDNA from animal tracks</h2>



<p>A unique aspect of this research involves the use of <a href="https://www.earth.com/news/environmental-dna-can-help-monitor-pollinators/" target="_blank" rel="noreferrer noopener">environmental DNA</a> (eDNA) found in the snow track footprints of polar bears. Dr. Micaela Hellström of <a href="https://www.mixresearch.se/" target="_blank" rel="noreferrer noopener">MIX Research Sweden AB</a>, the lead author of the study, explains that the tracks contain fresh cells with intact DNA.</p>



<p>“The tracks usually contain fresh cells, and the DNA is intact because of the cold ‘storage’ temperature. DNA that has passed the gut is much more degraded and therefore more challenging to work on,” said Hellström.</p>



<p>The team collected snow from individual tracks of Alaskan <a href="https://www.earth.com/news/radar-imaging-will-help-protect-polar-bears-from-human-disturbances/" target="_blank" rel="noreferrer noopener">polar bears</a> and Swedish Eurasian lynxes, both in the wild and captivity, as well as from a captive snow leopard. Confirming the accuracy of the genotypes derived from this snow track DNA, additional materials like hair, saliva, and mucus were also sampled. </p>



<h2 class="wp-block-heading" id="h-footprint-dna-analysis-results">Footprint DNA analysis results</h2>



<p>The researchers sampled 24 wild polar bear tracks and 44 wild <a href="https://www.earth.com/news/lynx-habitat-selection-is-heavily-influenced-by-human-disturbance/" target="_blank" rel="noreferrer noopener">lynx</a> tracks. They melted and filtered the snow from these tracks to collect environmental DNA, which they then analyzed using microsatellite analysis. </p>



<p>Despite the low concentrations of DNA in the tracks collected from the wild, they successfully retrieved nuclear DNA from 87.5% of the wild <a href="https://www.earth.com/news/how-do-polar-bears-get-traction-on-ice/" target="_blank" rel="noreferrer noopener">polar bear</a> tracks and 59.1% of the wild <a href="https://www.earth.com/news/lynx-population-in-france-is-on-the-brink-of-extinction/" target="_blank" rel="noreferrer noopener">lynx</a> tracks. They managed to genotype 13 of the wild polar bear samples, identifying 12 different individuals.</p>



<p>When focusing on the lynx tracks sampled by trained personnel, the genotyping success rate improved significantly. The scientists retrieved nuclear DNA from 76% of the samples collected by these trained individuals, and they successfully genotyped 24% of these samples.</p>



<p>This non-invasive sampling technique, despite a lower success rate compared to traditional methods, offers considerable advantages. It not only reduces the stress and danger associated with physical capture but also allows for larger sample sizes due to its ease of collection. </p>



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



<p>The potential of this technique to inform conservation strategies, understand animal populations and behaviors, and manage human-animal conflicts is immense.</p>



<p>Dr. Lancaster expresses hope that this method will be adopted widely by the polar bear research community, involving hunters, volunteers, and Indigenous communities. She says, “We hope this method will be taken up by the <a href="https://www.earth.com/news/polar-bears-threatened-by-toxic-chemicals-in-melting-sea-ice/" target="_blank" rel="noreferrer noopener">polar bear</a> research community, with the involvement of hunters, volunteers, and Indigenous communities, as a new way to collect information on polar bears.”</p>



<p>The team also anticipates the expansion of this technique to other animals living in snowy environments, having already demonstrated its effectiveness with lynx and snow leopards.</p>



<p>In summary, this groundbreaking research in DNA analysis using <a href="https://www.earth.com/news/scientists-vacuumed-animal-dna-from-a-forest-and-the-results-are-amazing/" target="_blank" rel="noreferrer noopener">environmental DNA</a> from snow tracks and footprints opens a new chapter in wildlife conservation. It promises a more humane, efficient, and inclusive approach to studying and protecting one of the Arctic's most iconic inhabitants, the polar bear, and potentially other species in similar environments.</p>



<p>The full study was published in the journal <em><a href="https://www.frontiersin.org/articles/10.3389/fcosc.2023.1250996/full" target="_blank" rel="noreferrer noopener">Frontiers in Conservation Science</a></em>.</p>

Footprint DNA helps scientists monitor elusive animals like polar bears

Polar bears, the majestic icons of the Arctic, are elusive...

<p>In late 2017, the Thomas Fire in Santa Barbara County became one of the most destructive <a href="https://www.earth.com/news/canadian-wildfires-of-2023-were-a-global-environmental-setback/">wildfires</a> in California's history. The fire led to the unprecedented closure of classes at <a href="https://www.ucsb.edu/" target="_blank" rel="noreferrer noopener">UC Santa Barbara</a> and widespread use of N95 masks. </p>



<p>This catastrophic event, however, presented a unique opportunity for scientists at the university. Huge amounts of wildfire ash had settled into the oceans, and the experts wanted to investigate what effect it might have on marine life.</p>



<h2 class="wp-block-heading" id="h-significant-discovery-nbsp">Significant discovery&nbsp;</h2>



<p>The team embarked on a mission to understand the effects of wildfire ash on ocean ecosystems - a subject that has been relatively unexplored compared to freshwater systems.</p>



<p>The researchers made a significant discovery: wildfire ash can actually fertilize marine ecosystems. This is in stark contrast to its toxic effects in freshwater environments.&nbsp;</p>



<h2 class="wp-block-heading" id="h-research-expedition-nbsp">Research expedition&nbsp;</h2>



<p>The team, led by Tanika Ladd, had to rapidly adapt their pre-planned expedition. "With a research cruise already on the calendar, the team jumped on the opportunity to investigate. “We planned this out in just a few weeks,” said Ladd.</p>



<p>“The fire broke out Dec. 4; our cruise was scheduled to go out on Dec. 17, and this clearly wasn’t in our plans for all of the cruise prep before the fire started.” The group quickly pivoted the entire cruise itinerary. Senior scientists sent off a flurry of grant applications, and the team revised the schedule a couple weeks before setting sail."</p>



<h2 class="wp-block-heading" id="h-how-the-research-was-conducted-nbsp">How the research was conducted&nbsp;</h2>



<p>Study co-author Eleanor Arrington collected ash samples from car windshields across Santa Barbara, creating a saltwater solution with the ash and then filtering out solid particles.&nbsp;</p>



<p>This solution was added to seawater cultures, which were incubated on deck of the research vessel. </p>



<h2 class="wp-block-heading" id="h-key-nutrients-nbsp">Key nutrients&nbsp;</h2>



<p>The team's measurements indicated a significant increase in particulate organic carbon in samples with added ash leachate, suggesting enhanced plankton growth and increased carbon drawdown from the atmosphere through photosynthesis.</p>



<p>Further analysis showed that the ash was enriching the seawater with key nutrients like nitrate, nitrite, ammonium, and silicic acid, which are essential for the growth of phytoplankton such as diatoms.&nbsp;</p>



<h2 class="wp-block-heading" id="h-potentially-toxic-metals">Potentially toxic metals</h2>



<p>The ash also introduced metals like copper and iron to the seawater. While essential in small quantities, these metals can be toxic at higher concentrations in freshwater ecosystems.&nbsp;</p>



<p>However, the vastness of the ocean dilutes these elements, reducing their potential harm.</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>This study sheds light on the complex interactions between terrestrial and marine ecosystems, particularly in the context of increasing wildfires.&nbsp;</p>



<p>The nutrients carried by wildfire ash into the ocean may boost primary production in coastal areas, especially in nutrient-limited regions like the Santa Barbara Channel.&nbsp;</p>



<p>"Coastal ecosystems may have increased primary production during these wildfires, but we need to know what this actually means on a global scale," said Ladd.</p>



<p>The study is published in the journal <a href="https://royalsocietypublishing.org/doi/10.1098/rspb.2023.1817" target="_blank" rel="noreferrer noopener"><em>Proceedings of the Royal Society B Biological Sciences</em></a>.</p>

Wildfire ash fertilizes the ocean and boosts marine life

In late 2017, the Thomas Fire in Santa Barbara County...

<p>In an unprecedented move, <a href="https://www.insta360.com/" target="_blank" rel="noreferrer noopener">Insta360</a> has successfully launched the first ultra-high-resolution cameras into Earth's orbit, offering an unparalleled view of our <a href="https://www.earth.com/news/massive-earth-like-planet-may-be-hiding-just-beyond-neptune/">planet</a>.&nbsp;</p>



<p>This monumental feat, which involved over a year of research, development, and testing, marks a significant milestone in space imaging.</p>



<h2 class="wp-block-heading" id="h-insta360-s-x2-cameras">Insta360's X2 cameras</h2>



<p>Insta360, a leading camera company based in Shenzhen, China, initiated the project in 2021. The team focused on adapting their commercially available X2 cameras for the rigors of space.&nbsp;</p>



<p>On January 16, the company launched two X2 cameras 500 kilometers into space and attached them to satellites. The cameras were designed to withstand the extreme conditions of space, including extreme temperatures and cosmic radiation.</p>



<h2 class="wp-block-heading" id="h-successful-project">Successful project</h2>



<p>"The project runs on hard work, but a fair bit of luck, too. Space can be unpredictable, and there is no backup hardware or software if the camera runs into any issues," said Insta360.</p>



<p>"Luckily, both cameras and their sensors are still fully functioning and offer an incredible look at outer space."</p>



<p>The cameras have now captured <a href="https://www.instagram.com/reel/C0MZ87HLEQb/" target="_blank" rel="noreferrer noopener">stunning images</a> of Earth, presenting the "Blue Marble" in extraordinary detail and from a unique 360-degree perspective.</p>



<h2 class="wp-block-heading" id="h-testing-insta360-cameras-for-space">Testing Insta360 cameras for space</h2>



<p>To prepare for the space environment, Insta360 utilized a thermal vacuum chamber or Space Environment Simulator.&nbsp;</p>



<p>The engineers faced the daunting task of modifying the cameras to endure the harsh conditions of space.&nbsp;</p>



<p>This process involved extensive testing, including exposure to extreme temperatures, radiation, and vacuum simulations, to ensure the cameras' functionality in orbit.</p>



<h2 class="wp-block-heading" id="h-overcoming-obstacles-nbsp">Overcoming obstacles&nbsp;</h2>



<p>One of the critical challenges was the cameras' response to extreme cold, leading to system crashes, and the impact of radiation on the sealing glue.&nbsp;</p>



<p>In addition, the vacuum environment tests revealed potential issues with lens pressure, threatening image resolution and quality. These hurdles were addressed to ensure the cameras' resilience and operational excellence in space.</p>



<h2 class="wp-block-heading" id="h-advanced-technology-nbsp">Advanced technology&nbsp;</h2>



<p>The X2 cameras boast an impressive 5.7K resolution, capturing 360-degree videos and photos of Earth against the backdrop of space.&nbsp;</p>



<p>The quality of these images surpasses the capabilities of standard viewing platforms, including YouTube and many high-end 4K TVs.</p>



<h2 class="wp-block-heading" id="h-extraordinary-earth-images">Extraordinary Earth images </h2>



<p>The success of this mission is attributed to collaborations with Media Storm and Spacety, a satellite company employing synthetic-aperture radar (SAR) systems. These systems enable high-resolution imaging comparable to larger satellites but with smaller antennas, showcasing innovative approaches in satellite technology.</p>



<p>Insta360's X2 cameras are set to orbit Earth every 90 minutes for two years, after which they will exit Earth's orbit and disintegrate in space.&nbsp;</p>



<p>This time frame offers a unique window for capturing extraordinary images of our planet and beyond, heralding a new era in space photography and exploration.</p>

Mega-high-resolution Earth images captured from orbit

In an unprecedented move, Insta360 has successfully launched the first...

<p>A recent study led by the <a href="https://www.uq.edu.au/" target="_blank" rel="noreferrer noopener">University of Queensland</a> has confirmed that being overweight impacts the body's immune response to SARS-CoV-2, the virus responsible for <a href="https://www.earth.com/news/air-pollution-associated-with-lower-covid-19-vaccine-responses/">COVID-19</a>. </p>



<p>This research was led by Marcus Tong, a PhD candidate in the School of Chemistry and Molecular Biosciences. The study provides crucial information for shaping future policies, particularly concerning vaccination and public health strategies.</p>



<h2 class="wp-block-heading" id="h-impaired-antibody-response-nbsp">Impaired antibody response&nbsp;</h2>



<p>The findings are primarily focused on the distinction between the body's response to SARS-CoV-2 infection and its response to COVID-19 vaccination in overweight individuals.&nbsp;</p>



<p>“We’ve previously shown that being overweight – not just being obese – increases the severity of SARS-CoV-2,” said Tong. “But this work shows that being overweight creates an impaired antibody response to SARS-CoV-2 infection but not to vaccination.”</p>



<h2 class="wp-block-heading" id="h-focus-of-the-study-nbsp">Focus of the study&nbsp;</h2>



<p>The research highlights a critical differentiation in how the body's immune system reacts to the virus naturally versus through the aid of vaccines.</p>



<p>To reach these conclusions, the experts collected and analyzed blood samples from individuals who had recovered from COVID-19. The participants were not reinfected during the study period, which spanned approximately 3 months and 13 months post-infection.&nbsp;</p>



<h2 class="wp-block-heading" id="h-critical-insights-nbsp">Critical insights&nbsp;</h2>



<p>“At 3 months post-infection, an elevated BMI was associated with reduced antibody levels,” explained Tong. “And at 13 months post-infection, an elevated BMI was associated with both reduced antibody activity and a reduced percentage of the relevant B cells, a type of cell that helps build these COVID-fighting antibodies.”</p>



<p>By contrast, the experts found that an elevated BMI did not affect the antibody response to the COVID-19 vaccination. This was observed approximately 6 months after the administration of the second vaccine dose.&nbsp;</p>



<p>This insight is particularly significant as it suggests that vaccination can offer effective protection against COVID-19 for overweight individuals, despite their impaired natural immune response to the virus.</p>



<h2 class="wp-block-heading" id="h-increased-risk-of-reinfection-nbsp">Increased risk of reinfection&nbsp;</h2>



<p>Professor Kirsty Short, commenting on the implications of these findings, emphasized the need for tailored health policies.&nbsp;</p>



<p>“If infection is associated with an increased risk of severe disease and an impaired immune response for the overweight, this group has a potentially increased risk of reinfection,” explained Dr. Short. “It makes it more important than ever for this group to ensure they’re vaccinated.”</p>



<h2 class="wp-block-heading" id="h-public-health-nbsp">Public health&nbsp;</h2>



<p>Dr. Short said that from a public health perspective, this data draws into question policies around boosters and lockdowns.</p>



<p>“We’d suggest that more personalized recommendations are needed for overweight people, both for ongoing COVID-19 management and future pandemics."</p>



<p>“Finally, the data provides an added impetus to improve SARS-CoV-2 vaccination in low-income countries, where there’s a high percentage of people who are overweight and are dependent on infection-induced immunity," said Dr. Short.</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>The study not only sheds light on the immediate concerns of managing COVID-19 but also underscores the broader implications for global health, particularly in low-income countries.&nbsp;</p>



<p>These regions, characterized by a high percentage of overweight individuals who rely on infection-induced immunity, face unique challenges in ensuring adequate SARS-CoV-2 vaccination coverage.</p>

Extra weight impairs the body's immune response to COVID-19

A recent study led by the University of Queensland has...

<p>Scientists at the <a href="https://www.virginia.edu/" target="_blank" rel="noreferrer noopener">University of Virginia</a> School of Medicine have made a remarkable discovery in the field of mental health. They have identified how Lactobacillus, a bacterium commonly found in fermented foods and yogurt, plays a crucial role in managing stress and potentially preventing mental health issues like depression and anxiety. </p>



<h2 class="wp-block-heading" id="h-much-needed-therapeutics">Much-needed therapeutics</h2>



<p>This research, led by Dr. Alban Gaultier and his team, is a significant advancement in understanding the individual roles of microorganisms in our body, particularly those that comprise our microbiota.</p>



<p>“Our discovery illuminates how gut-resident Lactobacillus influences mood disorders, by tuning the immune system,” said Dr. Gaultier. “Our research could pave the way towards discovering much-needed therapeutics for anxiety and depression.”</p>



<h2 class="wp-block-heading" id="h-targeting-microbiota-nbsp">Targeting microbiota&nbsp;</h2>



<p>The microbiota, consisting of various microorganisms living in and on our bodies, has become a focus of scientific research due to its profound impact on our health, both physical and mental.&nbsp;</p>



<p>Disruptions in the microbiota have been linked to numerous diseases, including the spread of cancer. Consequently, targeting these microorganisms has emerged as a promising strategy to combat various illnesses.</p>



<h2 class="wp-block-heading" id="h-lactobacillus-bacteria">Lactobacillus bacteria</h2>



<p>Dr. Gaultier's team has concentrated on the Lactobacillus bacteria. Previous research from his lab showed the potential of this bacteria in reversing depression in lab mice. However, the mechanisms behind this effect were not fully understood.&nbsp;</p>



<p>“We were aware from our prior research that Lactobacillus was beneficial in improving mood disorders and was lost following psychological stress, but the underlying reasons remained unclear, primarily due to the technical challenges associated with studying the microbiome,” said Dr. Gaultier.</p>



<h2 class="wp-block-heading" id="h-critical-insights">Critical insights</h2>



<p>To investigate further, the team focused on a collection of bacteria known as Altered Schaedler Flora, which includes Lactobacillus, to conduct their studies without the need for antibiotics.</p>



<p>The research clarified the role of Lactobacilli in influencing behavior. The experts discovered that these bacteria maintain levels of interferon gamma, an immune mediator that regulates the body’s stress response and helps prevent depression.&nbsp;</p>



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



<p>This finding is pivotal as it opens new avenues for developing treatments for mental health conditions where Lactobacillus plays a vital role.</p>



<p>For example, specially formulated probiotic supplements could be developed for patients struggling with depression that will optimize their levels of helpful Lactobacillus.</p>



<p>“With these results in hand, we have new tools to optimize the development of probiotics, which should speed up discoveries for novel therapies,” said study co-author Dr. Andrea R. Merchak. “Most importantly, we can now explore how maintaining a healthy level of Lactobacillus and/or interferon gamma could be investigated to prevent and treat anxiety and depression.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-more-about-fermented-foods">More about fermented foods</h2>



<p>Fermented foods are a diverse group of food items that have undergone a process of fermentation, where natural bacteria feed on the sugar and starch in the food, creating lactic acid.&nbsp;</p>



<p>This process not only preserves the food but also creates beneficial enzymes, b-vitamins, Omega-3 fatty acids, and various strains of probiotics.&nbsp;</p>



<h3 class="wp-block-heading" id="h-origin">Origin</h3>



<p>The origin of fermentation is deep-rooted in human history, having been used for thousands of years as a way to preserve food and enhance its nutritional value.</p>



<h3 class="wp-block-heading" id="h-examples-nbsp">Examples&nbsp;</h3>



<p>Common examples of fermented foods include yogurt, kefir, sauerkraut, tempeh, kimchi, and miso. Each of these foods undergoes a unique fermentation process that contributes to its distinct flavor and texture.&nbsp;</p>



<p>Yogurt and kefir, for instance, are made by fermenting milk, which results in a creamy product rich in probiotics. Sauerkraut and kimchi are fermented cabbage products known for their sour taste and digestive benefits.</p>



<h3 class="wp-block-heading" id="h-physical-health-benefits-nbsp">Physical health benefits&nbsp;</h3>



<p>The health benefits of fermented foods are significant. They are known to improve digestion and gut health due to the presence of probiotics, which help balance the gut microbiome. This balance is crucial for proper digestion, absorption of nutrients, and even the functioning of the immune system.&nbsp;</p>



<p>Additionally, the fermentation process can increase the availability of vitamins and minerals in food, making these nutrients easier for the body to absorb.</p>



<h3 class="wp-block-heading" id="h-mental-health-benefits">Mental health benefits</h3>



<p>Moreover, recent research has linked the consumption of fermented foods to improved mental health. The gut-brain axis, a complex communication network between the gut and the brain, plays a crucial role in this regard.&nbsp;</p>



<p>By enhancing gut health, fermented foods can potentially influence brain health, leading to reductions in anxiety and depression symptoms.</p>



<p>Despite their benefits, fermented foods may not be suitable for everyone. People with histamine intolerance or those using certain types of medication should consult with a healthcare provider before incorporating them into their diet.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1016/j.bbi.2023.11.001" target="_blank" rel="noreferrer noopener"><em>Brain Behavior and Immunity</em></a>. </p>

Fermented foods combat depression and anxiety

Scientists at the University of Virginia School of Medicine have...

<p>Scientists at the <a href="https://www.tum.de/en/" target="_blank" rel="noreferrer noopener">Technical University of Munich</a> (TUM) have discovered that a day on Earth could eventually extend to 25 hours. The research marks a significant advancement in understanding Earth's rotation through rotational dynamics.</p>



<p>Contrary to common belief, Earth's rotation does not adhere to a precise 24-hour cycle. This inconsistency is attributed to the Earth's heterogeneous composition - a blend of various solids and liquids, each influencing the planet's rotational speed.</p>



<h2 class="wp-block-heading" id="h-improving-climate-models">Improving climate models</h2>



<p>“Fluctuations in rotation are not only important for astronomy, we also urgently need them to create accurate climate models and to better understand <a href="https://www.earth.com/news/forecasters-warn-of-weather-chaos-as-el-nino-arrives-early/">weather</a> phenomena like El Niño,” said Ulrich Schreiber, the project lead at the Observatory for TUM. “And the more precise the data, the more accurate the predictions.”</p>



<p>TUM's breakthrough centers on the enhancement of a ring laser, a sophisticated device capable of measuring the Earth's rotation with remarkable precision.&nbsp;</p>



<p>This laser, housed within the <a href="https://www.gfz-potsdam.de/en/section/hydrology/infrastructure/geodetic-observatory-wettzell" target="_blank" rel="noreferrer noopener">Geodetic Observatory Wettzell</a>, operates within a specially designed pressurized chamber buried 20 feet underground. It comprises a laser ring gyroscope and a 13.1-foot-wide "racetrack," all meticulously calibrated to ensure that external factors minimally influence the laser's readings.</p>



<h2 class="wp-block-heading" id="h-earth-s-rotation-speed-varies">Earth's rotation speed varies</h2>



<p>The device uses a complex system of lasers and mirrors to accurately detect variances in the speed of Earth’s rotation. These differences are indicated by the fluctuating frequencies between two laser beams, with larger discrepancies signifying faster rotation. </p>



<p>For instance, at the equator, where the Earth rotates at 15 degrees per hour, the ring laser records a frequency of 348.5 Hz, which subtly changes by mere millionths of a Hertz daily.&nbsp;</p>



<p>However, achieving exact measurements with this technology is challenging due to the inherent asymmetry in the device's design.&nbsp;</p>



<h2 class="wp-block-heading" id="h-precise-measurements-of-earth-s-rotation">Precise measurements of Earth's rotation </h2>



<p>Over the past four years, geodesists have developed a theoretical model for laser oscillations to account for these systematic effects.&nbsp;</p>



<p>By incorporating a corrective algorithm, they can now precisely eliminate these discrepancies from their measurements, enabling them to measure Earth's rotation to an astonishing nine decimal places. This equates to a variance of approximately a fraction of a millisecond each day.</p>



<p>"In geosciences, time resolution levels this high are absolutely novel for standalone ring lasers. In contrast to other systems, the laser functions completely independently and doesn't require reference points in space," said Professor Urs Hugentobler.</p>



<p>"With conventional systems, these reference points are created by observing the stars or using satellite data. But we're independent of that kind of thing and also extremely precise."</p>



<h2 class="wp-block-heading" id="h-evolving-dynamics">Evolving dynamics</h2>



<p>Interestingly, the Earth's day length has been gradually increasing over time. During the era of the dinosaurs, a day lasted only 23 hours, and 1.4 billion years ago, it was a mere 18 hours and 41 minutes.&nbsp;</p>



<p>Projections suggest that in 200 million years, a day will extend to 25 hours. This evolving dynamic of Earth's rotation underscores the importance of advanced measurements, though it leaves one to wonder who or what might be around to witness these changes in the distant future.</p>



<h2 class="wp-block-heading" id="h-more-about-earth-s-rotation">More about Earth's rotation</h2>



<p>As previously discussed, Earth's rotation, a fundamental aspect of our planet's existence, presents a fascinating subject combining aspects of astronomy, physics, and geology. Let's now dive deeper into the intricate details of how and why Earth rotates, the effects this rotation has on life and the environment, and the scientific methods used to study it.</p>



<h3 class="wp-block-heading" id="h-understanding-earth-s-rotation">Understanding Earth's rotation</h3>



<p>Earth rotates on its axis, an imaginary line that runs from the North Pole to the South Pole, which is how we have the recurring cycle of day and night. This rotation occurs in a counterclockwise direction when viewed from above the North Pole, and it takes approximately 24 hours to complete one full turn. Although, as we learned above, that time period is slowly increasing.</p>



<p>The rotation of Earth stems from the planet's formation. About 4.6 billion years ago, Earth formed from a cloud of gas and dust. As this material coalesced under gravity, it began to spin, leading to the rotation we observe today. The conservation of angular momentum, a principle in physics, dictates that Earth maintains this rotation unless acted upon by an external force.</p>



<h3 class="wp-block-heading" id="h-effects-of-earth-s-rotation">Effects of Earth's rotation</h3>



<p>The most direct effect of Earth's rotation is the alternation between day and night. As Earth spins, different parts of the planet face the Sun, experiencing daylight, while others turn away, falling into night.</p>



<p>Earth's rotation also influences climate and weather patterns. The Coriolis effect, resulting from the rotation, causes moving air and water to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection plays a crucial role in shaping weather systems and ocean currents.</p>



<p>The division of Earth into 24 time zones relates directly to its rotation. Each zone represents the section of Earth that experiences a particular hour of the day, aligning daily activities with the position of the Sun in the sky.</p>



<h3 class="wp-block-heading" id="h-studying-earth-s-rotation">Studying Earth's rotation</h3>



<p>Scientists use astronomical observations to study Earth's rotation. By monitoring the positions of stars and other celestial bodies, they can measure the precise rate and changes in Earth's spin.</p>



<p>Satellites equipped with advanced sensors provide another means to study Earth's rotation. These instruments can detect subtle changes in the rotation speed and the orientation of the Earth's axis.</p>



<p>Geological records, such as sediment layers and ice cores, also offer insights into historical changes in Earth's rotation. These records help scientists understand how the rotation has varied over millions of years.</p>



<p>In summary, Earth's rotation is a dynamic process with profound impacts on the planet. It shapes our daily experience of time, influences weather and climate patterns, and plays a key role in the functioning of our world. Through a combination of astronomical, satellite, and geological studies, scientists continue to unravel the complexities of Earth's rotation, deepening our understanding of this fundamental planetary feature.</p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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



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



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



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