<p>A small, cool star 40 light-years away has a planet that just might hold on to an atmosphere. Astronomers used the James Webb Space Telescope (JWST) to watch that world, TRAPPIST-1e, pass in front of its star four times and extract the planet’s faint atmospheric fingerprint.</p>



<p>A new paper reports those observations and what they can - and cannot - show about the gases above this rocky surface. </p>



<p>The team can already reject a thick, hydrogen-dominated atmosphere, but the data are not yet strong enough to prove what is there on the planet instead.</p>



<p>Néstor Espinoza from the <a href="https://www.stsci.edu/home" target="_blank" rel="noreferrer noopener">Space Telescope Science Institute</a> (STScI) led the analysis with the JWST Telescope Scientist Team.</p>



<h2 class="wp-block-heading" id="h-star-activity-masks-trappist-1e">Star activity masks TRAPPIST-1e</h2>



<p>TRAPPIST-1 is a <a href="https://www.earth.com/news/planets-orbiting-red-dwarf-stars-may-not-be-habitable-ultraviolet-uv-radiation/">red dwarf star</a>, a compact and relatively cool star type that often flares and develops spots in ways that upset precise measurements. </p>



<p>That activity complicates the search for air around its planets because changes from the star can masquerade as signs from a planet’s atmosphere.</p>



<p>TRAPPIST-1e sits in the star’s habitable zone - the region where a planet could support liquid water on its surface if pressure and temperature are suitable. </p>



<p>That alone does not make it hospitable, since the star’s outbursts could strip or scramble any atmosphere over time.</p>



<p>Earlier Webb data on the inner siblings, such as TRAPPIST-1b, found little evidence of a substantial atmosphere. </p>



<p>That result keeps expectations in check and places more weight on careful, repeated measurements for the middle worlds.</p>



<p>NASA shared a technical feature explaining that the first four TRAPPIST-1e observations are not enough to confirm an atmosphere. </p>



<p>The figure shows that models with and without an atmosphere still overlap in the range allowed by today’s data.</p>



<h2 class="wp-block-heading" id="h-what-the-telescope-actually-measured">What the telescope actually measured</h2>



<p>TRAPPIST-1e is an exoplanet, a planet beyond our solar system. When it crosses the star, a tiny bit of starlight filters through any air at the planet’s edge, and that light carries molecular fingerprints.</p>



<p>This method is called transmission spectroscopy, and it spreads the light into wavelengths to see where particular gases absorb. </p>



<p>Webb’s NIRSpec instrument recorded four such transits in 2023, covering wavelengths where gases like water vapor, methane, and carbon dioxide could show up clearly.</p>



<p>Because the <a href="https://www.earth.com/news/interstellar-tunnel-cosmic-channel-discovered-connects-our-solar-system-to-other-stars/">star</a> itself has features that can change over minutes to hours, the team built models to separate stellar effects from any possible planetary signals. </p>



<p>They also combined the four events to reduce random noise while being careful not to blur out real, repeatable features.</p>



<h2 class="wp-block-heading" id="h-no-primary-atmosphere-detected">No primary atmosphere detected</h2>



<p>A hydrogen-rich atmosphere on the planet would have produced large, easily seen features in the spectrum. </p>



<p>The team reports that such primary atmospheres - dominated by hydrogen at levels above roughly 80 percent by volume - are inconsistent with the data.</p>



<p>Ana Glidden is a postdoctoral researcher in MIT's Department of Earth, Atmospheric and Planetary Sciences and the MIT <a href="https://www.space.mit.edu/" target="_blank" rel="noreferrer noopener">Kavli Institute for Astrophysics and Space Research.</a></p>



<p>“The idea is: If we assume that the planet is not airless, can we constrain different atmospheric scenarios? Do those scenarios still allow for liquid water at the surface?” she said. </p>



<p>Glidden noted that the results rule out a hydrogen-dominated atmosphere and tighten limits on several secondary-atmosphere scenarios.&nbsp;</p>



<p>A warm, nitrogen-rich mix remains possible, along with other secondary atmospheres that could arise from volcanic outgassing. </p>



<p>Those would appear much subtler in the data than hydrogen and require more than four transits to emerge from the noise.</p>



<h2 class="wp-block-heading" id="h-stellar-flares-complicate-tests">Stellar flares complicate tests</h2>



<p><a href="https://www.earth.com/news/trappist-1-has-seven-earth-like-planets-that-may-support-life/">TRAPPIST-1</a>’s surface has star spots and frequent flares that change its spectrum over time. </p>



<p>That “stellar contamination” can either add or remove features in the planetary spectrum and, if not modeled correctly, can be misleading.</p>



<p>To tackle that, the authors used Gaussian processes, a flexible statistical tool that learns the typical shape and size of the star’s variations and then subtracts them. </p>



<p>That approach does not assume a perfect star model, which is wise when the star is as active as this one.</p>



<p>The goal is to treat any wiggles that change from one visit to the next as coming from the star, and any persistent pattern as likely belonging to the planet. Webb’s stability helps here, but the source star’s behavior still sets the pace.</p>



<h2 class="wp-block-heading" id="h-trappist-1e-air-circulation">TRAPPIST-1e air circulation</h2>



<p>A nitrogen-rich atmosphere would resemble Earth in broad strokes, though details such as oxygen, water vapor, and methane would matter greatly. </p>



<p><a href="https://www.earth.com/news/nitrogen-was-plentiful-for-early-life-on-earth/">Nitrogen</a> alone does not prove anything about life on the planet, but it suggests a heavier, secondary atmosphere capable of maintaining surface pressure.</p>



<p>“We are seeing two possible explanations," said Ryan MacDonald, Lecturer in Extrasolar Planets in the School of Physics and Astronomy at the <a href="https://www.st-andrews.ac.uk/" target="_blank" rel="noreferrer noopener">University of St Andrews</a>.</p>



<p>"The most exciting possibility is that TRAPPIST-1e could have a so-called secondary atmosphere containing heavy gases like nitrogen. But our initial observations cannot yet rule out a bare rock with no atmosphere.” </p>



<p>Independent of biology, an atmosphere changes surface temperature and how heat moves from day to night. On a tidally locked world, that could be the difference between an ice cap and a stable ocean.</p>



<h2 class="wp-block-heading" id="h-webb-and-trappist-1e">Webb and TRAPPIST-1e</h2>



<p>The team plans many more transits to shrink error bars and test for specific gases. More visits let the statistics work, and they also average over the star’s mood swings.</p>



<p>“In the coming years we will go from four JWST observations of TRAPPIST-1e to nearly twenty," said MacDonald. </p>



<p>"We finally have the telescope and tools to search for habitable conditions in other star systems, which makes today one of the most exciting times for astronomy.”</p>



<p>As the dataset grows, scientists can check for methane and <a href="https://www.earth.com/news/carbon-dioxide-hydrogen-peroxide-discovered-on-plutos-moon-charon/">carbon dioxide</a> together and run climate models that test whether liquid water could persist at the surface. </p>



<p>Caution remains the watchword until a clear atmospheric pattern repeats across many passes.</p>

Nearby rocky planet may hold an atmosphere fit for life

A small, cool star 40 light-years away has a planet that just might hold on to an atmosphere. Astronomers used the James Webb Space Telescope (JWST) to watch that world, TRAPPIST-1e, pass in front of its star four times and extract the planet’s faint atmospheric fingerprint. A new paper reports those observations and what they can - and cannot - show about the gases above this rocky surface. The team can already reject a thick, hydrogen-dominated atmosphere, but the data are not yet strong enough to prove...

<p>Humans stand apart from many other primates by taking more time to mature, relying on a supportive network of parents, grandparents, and community members during a long period of childhood. </p>



<p>This extended period of growth has long been considered crucial for acquiring the abilities required to thrive in a socially complex environment. </p>



<p>For a while, scientists have connected this slow development to the considerable energy demands of a growing brain. Experts remain intrigued by these social patterns.</p>



<p>Yet, a near-adult fossil of early Homo from the Dmanisi site in Georgia suggests there could be another explanation.</p>



<p>The remains, dated to about 1.77 million years ago, shed light on the interplay between cultural learning and childhood length, raising the idea that the traditional “big brain - long childhood” concept may not be the full story. </p>



<p>Christoph Zollikofer from the <a href="https://www.uzh.ch/en.html" target="_blank" rel="noreferrer noopener">University of Zurich</a> played a central part in investigating the unexpected details that have come to light. This site reshaped views on early ancestry.</p>



<h2 class="wp-block-heading" id="h-tracing-human-childhood-in-ancient-fossils">Tracing human childhood in ancient fossils</h2>



<p>Researchers applied synchrotron imaging to examine dental microstructures. </p>



<p>“Childhood and cognition do not fossilize, so we have to rely on indirect information. Teeth are ideal because they fossilize well and produce daily rings, in the same way that trees produce annual rings, which record their development,” explains Zollikofer. </p>



<p>This approach allowed the team to chart growth phases with remarkable precision. Such approaches boost accuracy in fossil studies.</p>



<p>“Dental development is strongly correlated with the development of the rest of the body, including brain development," another specialist, Paul Tafforeau from the ESRF, remarks.</p>



<p>"Access to the details of a fossil <a href="https://www.earth.com/news/early-humans-thrived-on-plant-based-diets-not-meat-alone-780000-years-ago/" target="_blank" rel="noreferrer noopener">hominid's dental growth</a> therefore provides a great deal of information about its general growth.” </p>



<p>The group’s effort began in 2005 and spanned about 18 years, benefiting from technological advances in synchrotron tomography. </p>



<p>The first scans took place in 2006, followed by initial results in 2007. High-resolution scans now guide innovative anthropological work.</p>



<h2 class="wp-block-heading" id="h-reconstructing-growth-from-dental-clues">Reconstructing growth from dental clues</h2>



<p>The team discovered something that defied the usual categories. </p>



<p>“We expected to find either dental development typical of <a href="https://www.earth.com/news/pierolapithecus-catalaunicus-recreating-face-of-an-ancient-human-ancestor/" target="_blank" rel="noreferrer noopener">early hominids</a>, close to that of the <a href="https://www.earth.com/news/world-gorilla-day-supporting-the-guardians-of-the-forest/" target="_blank" rel="noreferrer noopener">great apes</a>, or dental development close to that of modern humans," explains Tafforeau.</p>



<p>"When we obtained the first results, we couldn't believe what we saw, because it was something different that implied faster molar crown growth than in any other fossil hominin or living great ape. It’s been a slow maturation, both technically and intellectually, to finally arrive at the hypothesis we are publishing today.” </p>



<p>In addition, the high-quality scans allowed the scientists to track growth from birth to death without damaging the specimen. Incremental examination helped reveal unexpected growth patterns.</p>

<p>Alongside that surprise, the analysis revealed a specific timeline for this individual’s life. </p>



<p>“The results showed that this individual died between 11 and 12 years of age, when his wisdom teeth had already erupted, as is the case in great apes at this age,” explains Vincent Beyrand, co-author of the study. </p>



<p>The front teeth initially progressed more quickly, while the back teeth took longer to complete. Every tooth layer illuminated unique ancient development.</p>



<h2 class="wp-block-heading" id="h-slower-development-in-human-childhood">Slower development in human childhood</h2>



<p>Additional evidence highlights that youth in this early Homo likely depended on adults for an extended stretch. </p>



<p>“This suggests that milk teeth were used for longer than in the great apes and that the children of this early Homo species were dependent on adult support for longer than those of the great apes,” explains Marcia Ponce de León from the University of Zurich and co-author of the study. </p>



<p>“This could be the first evolutionary experiment of prolonged childhood.” </p>



<p>One skeleton found at Dmanisi belonged to a much older individual who had lost all teeth but survived with help from others. Communal responsibilities likely shaped new social conventions.</p>



<p>According to David Lordkipadnize of the <a href="https://museum.ge/index.php?m=350&amp;lang=eng&amp;museum=54&amp;lng=eng" target="_blank" rel="noreferrer noopener">National Museum of Georgia</a>, “The fact that such an old individual was able to survive without any teeth for several years indicates that the rest of the group took good care of him.” </p>



<p>The presence of multiple generations within the same community could have enabled knowledge to flow more freely. </p>



<p>That knowledge might have included food processing strategies, tool use, or group coordination. Older guardians offered knowledge to younger members.</p>



<h2 class="wp-block-heading" id="h-what-does-all-of-this-mean">What does all of this mean?</h2>



<p>Scientists propose that lengthening childhood in early humans might have come first, driving <a href="https://www.earth.com/news/when-did-early-humans-first-start-wearing-clothes-and-why-parasites-lice/" target="_blank" rel="noreferrer noopener">cultural transmission</a> and social learning. </p>



<p>Over time, this dynamic may have supported brain expansion, rather than the brain growing first and pushing for extended development. </p>



<p>It appears that maturing slowly allowed young individuals to absorb a growing body of information from older members of the group. </p>



<p>It also permitted older members to share their hard-earned expertise for a lengthier period. Continued support helped cultivate lasting cultural capacities.</p>



<p>Then, as the amount of information to be transmitted increased, evolution would have favored an increase in brain size and a delay in adulthood, allowing us both to learn more in childhood and to have the time to grow a larger brain despite limited food resources. </p>



<p>By focusing on how children rely on social networks early in life, this fossil from Dmanisi emphasizes the possibility that extended childhood and intergenerational support played a decisive role in shaping the path toward modern Homo sapiens. </p>



<p>Researchers are now poised to reexamine the conventional views on what sparked the long adolescence so familiar to us today. Ongoing research keeps clarifying childhood’s formative contribution to humanity.</p>

Fossil teeth discovery may explain why humans have such long childhoods

Humans stand apart from many other primates by taking more...

<p>Climate targets set by nations under the Paris Agreement outline voluntary commitments to reducing greenhouse gas emissions. These targets, known as Percentage Reduction Pledges (PRPs), reflect the commitments of individual countries to combating climate change. </p>



<p>However, this does not necessarily reflect the willingness of citizens in these countries to contribute financially to climate action.</p>



<p>A recent study from the <a href="https://uol.de/en" target="_blank" rel="noreferrer noopener">University of Oldenburg</a> in Germany examines the question of how closely the PRPs represent citizen buy in, in terms of willingness to contribute financially. The research explores the relationship between national climate targets and the public's willingness to support <a href="https://www.earth.com/news/climate-initiative-led-to-health-benefits-for-800-u-s-children/" target="_blank" rel="noreferrer noopener">climate initiatives</a> financially. </p>



<p>The findings reveal that, while higher-income countries tend to set more ambitious reduction goals, their populations are often less willing to contribute personally.</p>



<h2 class="wp-block-heading" id="h-climate-targets-and-public-willingness">Climate targets and public willingness</h2>



<p>The experts analyzed climate pledges from 123 countries, and used data from nearly 130,000 individuals surveyed in 125 nations as part of the Global Climate Change Survey.</p>



<p>The findings highlight that, while 89% of respondents believe their governments should take stronger <a href="https://www.earth.com/news/conservatives-liberals-unite-climate-action-despite-different-beliefs/" target="_blank" rel="noreferrer noopener">climate action</a>, only 69% expressed willingness to allocate 1% of their income toward climate mitigation.</p>



<p>The analysis uncovered key economic and environmental factors that influence both national pledges and individual contributions. Higher per-capita income and emissions correlated with more ambitious governmental targets. However, the same factors negatively influenced public willingness to contribute. </p>



<p>In wealthier, high-emission nations, citizens were less inclined to accept personal financial sacrifices in support of climate initiatives.</p>



<p>Temperature trends further shaped responses. <a href="https://www.earth.com/news/brutal-effects-of-climate-change-have-already-arrived-in-the-uk/" target="_blank" rel="noreferrer noopener">Warmer countries</a> demonstrated higher individual willingness to contribute, whereas colder countries adopted stronger national targets. </p>



<p>The study suggests that residents of colder regions may perceive climate change as a less immediate threat, making them less willing to engage in mitigation efforts.</p>



<h2 class="wp-block-heading" id="h-public-support-of-climate-policies">Public support of climate policies </h2>



<p><a href="https://www.earth.com/news/the-flood-disaster-in-germany-raises-new-questions-about-extreme-precipitation/" target="_blank" rel="noreferrer noopener">Germany</a> exemplifies this trend. It ranks among the top nations in climate pledges, committing to a 39.7% emissions reduction between 2019 and 2030. This places it 12th out of 123 countries in terms of its PRP.</p>



<p>Yet, despite its ambitious government targets, public willingness to contribute financially remains lower than in many other countries. Germany ranks 74th in this category, with 67.9% of its citizens agreeing to allocate a portion of their income toward climate action. </p>



<p>Meanwhile, only 86% of German respondents supported stronger governmental climate policies, ranking the country 89th globally.</p>



<h2 class="wp-block-heading" id="h-the-ethical-and-political-dilemma">The ethical and political dilemma</h2>



<p>The study interprets these findings as a reflection of a broader tension between climate policy and public perception. </p>



<p>The United Nations’ principle of "common but differentiated responsibilities" emphasizes equity in climate action. However, individuals often prioritize economic considerations over ethical responsibility.</p>



<p>"People assume that the lower the temperatures in a country are, the less impact climate change will have there," explained Dr. Heinz Welsch, an environmental economist at the University of Oldenburg.</p>



<p>Additionally, individuals in <a href="https://www.earth.com/news/industrialized-countries-owe-roughly-170-trillion-for-co2-emissions/" target="_blank" rel="noreferrer noopener">high-emission nations</a> worry about economic setbacks caused by strict climate regulations. </p>



<p>"Cost-benefit calculations, therefore, make it likely that in colder, richer and more carbon-intensive countries there will be less willingness to contribute to climate protection," said Dr. Welsch.</p>



<p>Another layer to this issue is democratic satisfaction. The research highlights a notable pattern: when a government's climate targets exceed public willingness to contribute, citizens report lower satisfaction with democracy.</p>



<p>While the study does not establish causation, it suggests that climate policies requiring public sacrifices without broad support could create political challenges.</p>



<h2 class="wp-block-heading" id="h-solutions-for-bridging-the-gap">Solutions for bridging the gap</h2>



<p>To bridge this gap, the report recommends policy strategies that minimize the economic cost of climate action for citizens. One such strategy can be a climate fund that recycles revenue from carbon taxes and uses it to benefit poorer citizens. </p>



<p>These structures can make effective climate policies that are ambitious and also acceptable to people, so action is not undertaken at the risk of political destabilization.</p>



<p>The study underlines the complexity of climate policy. While governments might make firm commitments, public involvement is still necessary for significant progress.</p>



<p>To develop effective, long-lasting climate policies, understanding the determinants of both policy and individual willingness is vital.</p>



<h2 class="wp-block-heading" id="h-urgency-of-achieving-climate-targets">Urgency of achieving climate targets</h2>



<p>Climate change is not an inevitable fate - it is a challenge that can be mitigated through decisive action.</p>



<p>Meeting climate targets is crucial to slowing global warming, reducing extreme weather events, and protecting ecosystems for future generations. </p>



<p>Every degree of warming prevented means fewer droughts, wildfires and damaging storms, and less increase in sea level.</p>



<p>The window for meaningful action is closing, but success remains within reach if nations commit to real, enforceable solutions. The future depends on turning promises into progress before it’s too late.</p>

Wealthier nations set bold climate targets,  but citizens give less

Climate targets set by nations under the Paris Agreement outline...

<p>Researchers have identified a measurable link between events in the earliest days of embryo development and a person’s long-term health. </p>



<p>Many people don't think much about what happens right after conception, yet those first steps can influence how <a href="https://www.earth.com/news/embryo-formation-is-shaped-by-electric-fields/" target="_blank" rel="noreferrer noopener">cells</a> stay strong over time.</p>



<p>In a recent study led by Professor Rebecca Robker from the <a href="https://www.adelaide.edu.au/" target="_blank" rel="noreferrer noopener">University of Adelaide</a>, scientists analyzed key components of DNA called <a href="https://www.nature.com/articles/s41467-025-57794-7" target="_blank" rel="noreferrer noopener">telomeres</a>, which act like protective ends on each chromosome.</p>



<h2 class="wp-block-heading" id="h-how-embryo-telomeres-protect-health">How embryo telomeres protect health</h2>



<p><a href="https://www.genome.gov/genetics-glossary/Telomere" target="_blank" rel="noreferrer noopener">Telomeres</a> have a special <a href="https://www.ahajournals.org/doi/10.1161/CIRCGENETICS.113.000485" target="_blank" rel="noreferrer noopener">DNA sequence</a> that shields our genetic material whenever cells split. They tend to shrink a little with each cell division, which is why older individuals often have shorter telomeres.</p>



<p>“Telomeres are the parts of chromosomes that influence growth and rejuvenation of our <a href="https://www.earth.com/news/embryo-development-shows-how-evolution-had-many-options-to-choose-from/" target="_blank" rel="noreferrer noopener">tissues</a>,” said Professor Robker. </p>



<p>Not only do they affect how efficiently our bodies manage cellular renewal, but telomeres also connect with how we handle stress.</p>



<h2 class="wp-block-heading" id="h-looking-inside-embryo-growth">Looking inside embryo growth</h2>



<p>“Reduced telomere length can be caused by embryonic cellular damage,” said study co-lead Dr. Yasmyn Winstanley. </p>



<p>The researchers found that the body’s condition at conception seems to shape how well these chromosomal ends develop. </p>



<p>“There are specific types of <a href="https://www.earth.com/news/hidden-viral-dna-may-control-human-embryonic-growth/" target="_blank" rel="noreferrer noopener">cellular damage</a> during the very first days of embryo development which cause the defect in the telomeres of the embryo. The process is highly responsive to signals from the mother’s body,” explained Dr. Winstanley. </p>



<h2 class="wp-block-heading" id="h-maternal-health-shapes-embryo-health">Maternal health shapes embryo health</h2>



<p>Conditions such as obesity can raise the risk of having shorter telomeres <a href="https://pubmed.ncbi.nlm.nih.gov/27751173/" target="_blank" rel="noreferrer noopener">at birth</a>. This has caught the attention of public health advocates because shorter telomeres in children can mean increased vulnerability to later challenges.</p>



<p>“Some babies are born with shorter telomeres than others, increasing their lifetime risk of chronic diseases associated with aging,” said Professor Robker. </p>



<p>Offspring may inherit a greater susceptibility to problems linked to heart function and other metabolic <a href="https://www.earth.com/news/plastic-pollution-kills-ocean-embryos-during-development/" target="_blank" rel="noreferrer noopener">processes</a>.</p>



<h2 class="wp-block-heading" id="h-a-possible-break-in-the-chain">A possible break in the chain</h2>



<p>“Until now it has not been clear how the length of telomeres is determined before birth,” said Professor Robker. </p>



<p>But her group has demonstrated that pre-conception factors set off cellular signals that change how these protective caps are established.</p>



<p>“We provide proof-of-concept that DNA resetting can be modulated in embryos where it is deficient, using currently available drugs,” said Professor Robker. </p>



<p>The researchers tested strategies to repair such damage in the embryo’s early hours.&nbsp;</p>



<h2 class="wp-block-heading" id="h-drugs-restore-embryo-telomere-health">Drugs restore embryo telomere health</h2>



<p>Therapies that support healthy <a href="https://www.science.org/doi/10.1126/science.1201940" target="_blank" rel="noreferrer noopener">mitochondria</a> inside eggs appear to help maintain or restore telomeres. Mitochondria drive cellular energy, and they also produce byproducts that can harm DNA when not balanced.</p>



<p>“Our identification of specific pharmaceutical compounds that can modulate telomeres during preconception and immediately following fertilization, means that there are therapeutic opportunities to optimise this biology,” explained Professor Robker.</p>



<p>The researchers are now working with <a href="https://www.globenewswire.com/search/organization/Vitaleon%2520Pharma" target="_blank" rel="noreferrer noopener">Vitaleon Pharma</a> to develop these findings for fertility specialists.</p>



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



<p>“These findings highlight that the health of women and girls should be a major focus of public health policies,” said Dr. Winstanley. </p>



<p>Public awareness around maintaining a healthy weight, balanced nutrition, and a supportive environment may therefore be key.</p>



<p>For many, the best start comes from paying attention to signs of metabolic strain. Experts advise timely monitoring of overall wellness, especially in individuals aiming to have children.</p>



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

Mom's health shapes how well an embryo develops

Researchers have identified a measurable link between events in the...

<p>For centuries, people have wondered how humans differ from other primates, particularly in terms of brain characteristics. </p>



<p>Recent scientific advancements suggest that some neural pathways in humans function with unique connections not seen in chimpanzees or macaques.</p>



<p>In a recent study, researchers examined these specialized <a href="https://www.earth.com/news/subtle-dna-changes-shaped-human-brain-evolution/" target="_blank" rel="noreferrer noopener">brain circuits</a> and found potential links to emotional regulation, social intelligence, and language capabilities. </p>



<p>The research was led by Rogier Mars from the <a href="https://www.ox.ac.uk" target="_blank" rel="noreferrer noopener">University of Oxford</a> and Katherine Bryant from <a href="https://www.univ-amu.fr/en" target="_blank" rel="noreferrer noopener">Aix-Marseille University</a>.</p>



<h2 class="wp-block-heading" id="h-human-brains-process-emotions-uniquely">Human brains process emotions uniquely</h2>



<p>Many <a href="https://royalsocietypublishing.org/doi/10.1098/rstb.2002.1099" target="_blank" rel="noreferrer noopener">studies</a> have pointed to the <a href="https://www.ncbi.nlm.nih.gov/books/NBK499919/" target="_blank" rel="noreferrer noopener">prefrontal cortex</a> as a major player in our capacity for focused attention, strategic thinking, and impulse control. </p>



<p>The new data suggests that the neural regions governing emotions and interpersonal bonds also have remarkable features in <a href="https://www.earth.com/news/from-genes-to-genius-what-makes-the-human-brain-unique/" target="_blank" rel="noreferrer noopener">humans</a>.</p>



<p>Areas governing empathy, reading facial cues, and interpreting subtle social signals exhibit patterns of connectivity that appear notably different in our species. </p>



<p>This could mean that group cooperation, moral reasoning, and emotional nuance are molded by unique brain pathways.</p>



<h2 class="wp-block-heading" id="h-prefrontal-cortex-and-beyond">Prefrontal cortex and beyond</h2>



<p>Peer-reviewed research has linked the prefrontal cortex to a variety of higher-order functions, including planning and problem-solving. </p>



<p>For decades, scientists assumed that these executive tasks primarily distinguished us from other primates.</p>



<p>Now, evidence indicates that other networks, particularly those involved with emotional learning, may be equally pivotal to our advanced behavior. The interplay between cognition and emotion adds another layer to the conversation about what makes us <a href="https://www.earth.com/news/dna-changes-supercharged-the-human-brain-but-at-a-cost/" target="_blank" rel="noreferrer noopener">human</a>.</p>



<h2 class="wp-block-heading" id="h-differences-in-human-and-chimp-brains">Differences in human and chimp brains</h2>



<p>Chimpanzees share over 98% of our DNA, a <a href="https://pubmed.ncbi.nlm.nih.gov/11170892/" target="_blank" rel="noreferrer noopener">fact</a> that highlights how closely related we are biologically.</p>



<p>Still, scans from a publicly accessible archive, which were collected prior to the 2015 guidelines by the U.S. Fish and Wildlife Service and the National Institutes of Health, reveal surprising differences in certain brain areas.</p>



<p>These structural distinctions include connections associated with communication, emotional depth, and social dynamics. By comparing chimpanzee, macaque, and human brains side by side, researchers can pinpoint pathways that might underlie our species’ unique traits.</p>



<h2 class="wp-block-heading" id="h-shifts-in-connectivity">Shifts in connectivity</h2>



<p>Specialized circuits in the <a href="https://my.clevelandclinic.org/health/body/16799-temporal-lobe" target="_blank" rel="noreferrer noopener">temporal</a> and <a href="https://my.clevelandclinic.org/health/body/24628-parietal-lobe" target="_blank" rel="noreferrer noopener">parietal lobes</a> appear to handle processes such as combining sensory input, linking events to context, and supporting sophisticated language. </p>



<p>By mapping these neural webs, scientists discover clusters of activity that seem exclusive to <a href="https://www.earth.com/news/can-ai-systems-learn-like-the-human-brain/" target="_blank" rel="noreferrer noopener">humans</a>.</p>



<p>According to the researchers, these hotspots could account for our tendency to form complex social alliances, interpret subtle linguistic cues, and adapt to changing environments. </p>



<p>When these findings are added to our understanding of the prefrontal cortex, the result is a bigger picture of how the human brain navigates everyday life.</p>



<h2 class="wp-block-heading" id="h-networks-in-brain-set-humans-apart">Networks in brain set humans apart</h2>



<p>Some neuroscience <a href="https://journals.physiology.org/doi/10.1152/physrev.00006.2011" target="_blank" rel="noreferrer noopener">investigations</a> relate language to specialized regions in the temporal lobe, where phonological and semantic processing occurs. </p>



<p>This aspect of connectivity might underpin our ability to learn thousands of words, structure them into sentences, and convey intricate ideas with ease.</p>



<p>Strong language networks show how communication evolved beyond simple sounds. Researchers believe that these changes did not arise from a single “language gene” but from a reconfiguration of multiple interlinked neural systems.</p>



<h2 class="wp-block-heading" id="h-what-it-all-means">What it all means</h2>



<p>“Our <a href="https://www.jneurosci.org/content/early/2025/02/23/JNEUROSCI.2017-24.2025" target="_blank" rel="noreferrer noopener">results</a> counter models that assign primacy to prefrontal cortex for human uniqueness,” wrote Bryant and colleagues. Human's social and emotional wiring might be as influential to our humanity as the well-studied prefrontal cortex.&nbsp;</p>



<p>This perspective broadens our view of what makes us tick, giving new weight to the roles of empathy, social signaling, and emotional interplay in setting our species apart. It also emphasizes that the human story is about more than just rational thinking.</p>



<p>In the future, scientists may examine how these specialized connections develop over a lifetime and whether they shift in different cultures. Such research could reveal how malleable our brains are and how our capacity for compassion, language, and community evolves.</p>



<p>Each study provides a stepping stone for deeper inquiries into the complexity of our neural wiring. Findings like these remind us that the human brain is not defined by a single region, but by a tapestry of linked networks.</p>



<h2 class="wp-block-heading" id="h-another-perspective-on-evolution">Another perspective on evolution</h2>



<p>Some anthropologists note that major shifts in diet, group size, and tool use likely influenced how certain networks in the brain matured over thousands of years. </p>

New brain pathways identified as being unique to humans

For centuries, people have wondered how humans differ from other...

<p>Feathers did not arrive in nature as fully formed tools for flight. Their development began long before birds took to the sky. The fossil record tells a story that stretches back over 200 million years.</p>



<p>Now, with the help of genetic tools and carefully timed experiments, scientists can reawaken ancient traits inside of modern embryos.</p>



<p>This is not just about feathers. It's about how complexity arises, how it endures, and how biology protects the structures it builds. By reversing certain steps in feather <a href="https://www.earth.com/news/from-dinosaurs-to-birds-the-mysterious-origin-of-feathers/" target="_blank" rel="noreferrer noopener">development</a>, researchers reveal a hidden resilience. </p>



<h2 class="wp-block-heading" id="h-feather-development-before-birds">Feather development before birds</h2>



<p>The earliest feathers didn’t help animals fly. Instead, they started as simple, hollow filaments. These "proto-feathers" likely emerged in some dinosaurs during the Triassic period, around 200 million years ago. </p>



<p>There’s even evidence they may have evolved earlier, in a common ancestor of dinosaurs and pterosaurs nearly 240 million years ago.</p>



<p>Unlike modern feathers, proto-feathers had no central shaft, no branching barbs, and no follicle. But they still served a purpose. They helped with insulation and may have acted as colorful or patterned signals during social interaction. </p>



<p>Over time, <a href="https://www.earth.com/news/bird-evolution-timeline-pushed-back-20-million-years-by-baminornis-zhenghensis-discovery/" target="_blank" rel="noreferrer noopener">natural selection</a> shaped feathers into complex tools that now support everything from flight to waterproofing.</p>



<p>This progression - from basic filaments to branched, aerodynamic feathers - didn’t happen randomly. It followed a path written in genes, using signaling pathways shared across the animal kingdom.</p>



<h2 class="wp-block-heading" id="h-clues-hidden-in-bird-embryos">Clues hidden in bird embryos</h2>



<p>Modern bird embryos offer a way to retrace this path. At the <a href="https://www.unige.ch/en/" target="_blank" rel="noreferrer noopener">University of Geneva</a>, Professor Michel Milinkovitch and his team have explored the genetics of feather formation. Their lab focuses on how molecular signals drive the development of skin structures like scales, hair, and feathers.</p>



<p>One such signaling system, the Sonic Hedgehog (Shh) pathway, plays a crucial role in shaping feathers. In earlier studies, the team activated this pathway in chicken embryos. </p>



<p>The result was remarkable - scales on the feet of the birds transformed into permanent feathers. That experiment proved how a single shift in signaling can alter skin identity.</p>



<p>But what would happen if the Shh pathway were blocked instead?</p>



<p>"Feathers, ancient and intricate, still hold secrets that science is just beginning to unlock," noted Rory Cooper, lead author of the study.</p>



<h2 class="wp-block-heading" id="h-ancient-feather-development-recreated">Ancient feather development recreated</h2>



<p>To investigate, the researchers injected a drug called sonidegib into <a href="https://www.earth.com/news/bird-wings-inspire-improvements-in-airplane-safety/" target="_blank" rel="noreferrer noopener">chicken</a> embryos on their ninth day of development.</p>



<p>This drug shuts down the Shh pathway by targeting a key protein called Smoothened. The timing was crucial - day nine is when feather placodes begin to form, marking the start of feather bud development.</p>



<p>The results were dramatic. Feather buds failed to grow and remained short and unbranched. The typical invagination that forms a feather follicle was absent. Instead, the skin developed smooth, hollow filaments - almost identical to proto-feathers seen in fossils.</p>



<p>This temporary block in development held until the fourteenth day. After that, something unexpected happened. Feather growth resumed on its own. Chicks that hatched had patches of bare skin, but over the next several weeks, those areas filled in with normal feathers.</p>



<h2 class="wp-block-heading" id="h-a-closer-look-at-how-feathers-recover">A closer look at how feathers recover</h2>



<p>The researchers tracked development from embryo to hatchling using imaging and RNA sequencing. They confirmed that the Shh pathway was indeed suppressed. </p>



<p>Key genes like Ptch1, Ptch2, and Gli1 were all turned down. These genes normally guide outgrowth, branching, and follicle formation. Blocking them prevented barbs and ridges from forming.</p>



<p>Microscopy revealed that in high-dose treatments, feather buds remained fused, stubby, and lacked branching. </p>



<p>Follicle invagination - the folding-in of the skin to support feather roots - was completely absent. But despite all this, the system rebounded. By 49 days after hatching, the chicks showed normal feather coverage.</p>



<p>The only part that didn’t return to normal? The flight feathers. These specialized feathers, located on the posterior edge of the wing, failed to form correctly in high-dose embryos. </p>



<p>Even weeks later, their positions were filled by smaller, contour-type <a href="https://www.earth.com/news/how-and-why-tropical-birds-are-so-strikingly-colorful-and-iridescent/" target="_blank" rel="noreferrer noopener">feathers</a>. This indicated that some aspects of feather identity are locked to narrow developmental windows.</p>



<h2 class="wp-block-heading" id="h-timing-is-everything">Timing is everything</h2>



<p>To verify that the observed effects were specific to Shh signaling, the team ran a second experiment. They combined the Shh-blocking drug with a Shh activator known as SAG. If feathers could be restored this way, it would confirm that both molecules act directly on the same pathway.</p>



<p>And they were. Chicks treated with both sonidegib and SAG developed normal feathers. Even when SAG was delivered one or two days after sonidegib, the feathers grew, branched, and invaginated as they should. </p>



<p>Only late treatment - beyond day eleven - led to partial recovery. This showed that timing is everything in embryonic development.</p>



<p>"Our experiments show that while a transient disturbance in the development of foot scales can permanently turn them into feathers, it is much harder to permanently disrupt feather development itself," noted Michel Milinkovitch.</p>



<h2 class="wp-block-heading" id="h-feathers-recover-scales-do-not">Feathers recover, scales do not</h2>



<p>This recovery points to something fundamental about feathers. They grow from follicles that contain stem cells. These cells regenerate feathers cyclically throughout a bird’s life. </p>



<p>In contrast, scales - like those on a bird’s foot - do not grow from follicles and cannot regenerate. That may explain why transformed foot scales remain feathers, while disrupted feathers bounce back.</p>



<p>Even at the gene expression level, this distinction is clear. After sonidegib treatment, the feathers showed temporary suppression of hundreds of genes tied to structure and shape - keratin production, signaling gradients, and branching formation. </p>



<p>But the spatial map of feather follicles remained intact. Once signaling returned, so did the feathers.</p>



<p>Flight feathers, however, rely on precise placement and signaling levels during a short developmental window. If Shh signaling is missing at that moment, the opportunity is lost. The feather becomes ordinary, not aerodynamic.</p>



<h2 class="wp-block-heading" id="h-ancient-mechanisms-modern-precision">Ancient mechanisms, modern precision</h2>



<p>The entire experiment rests on a principle called reaction-diffusion. It’s a model that explains how patterns like stripes, spots, and ridges form in living tissues. </p>



<p>The Shh protein works as an activator, while another molecule, Bmp2, acts as its inhibitor. Together, they create a spatial map that tells cells where to grow barbs, shafts, or follicles.</p>



<p>By altering the Shh signal, scientists rewrote this map. The result: broad stripes of gene activity replaced the usual dotted pattern of feather placodes. This type of disruption aligns with theories on how feathers evolved from simpler, unbranched structures. </p>



<p>Proto-feathers didn’t have a patterned map yet - just the beginnings of one.</p>



<h2 class="wp-block-heading" id="h-feather-development-and-evolution">Feather development and evolution</h2>



<p>The study does more than recreate an ancient structure. It shows that feather development is built to recover from disruption. </p>



<p>This makes sense from an evolutionary point of view. Feathers are essential to survival in many bird species. Evolution may have shaped them to resist failure - much like a city has backup systems to keep it running.</p>



<p>And yet, these systems remain open to change. By manipulating just one pathway, scientists can trigger a full shift in identity - from scale to feather. Or they can recreate traits that vanished millions of years ago.</p>



<p>It’s a reminder that the genetic blueprint of life is both sturdy and flexible. The key lies not in the parts themselves, but in the timing and tuning of their signals. Feathers evolved through such changes - and continue to teach us how form and function intertwine across deep time.</p>

Chicken embryos reveal secrets of early feather development

Feathers did not arrive in nature as fully formed tools...

Photo,Of,Fresh,Pistachios,On,A,Tree

<p>California grows nearly all of the nation’s pistachios, producing 99% of the crop and contributing close to $3 billion annually to the state’s economy. </p>



<p>Despite their value, pistachios haven’t received as much scientific attention as other crops - mainly due to the absence of a complete, high-quality genetic map. But that is finally changing.</p>



<p>Scientists at the <a href="https://www.ucdavis.edu/" target="_blank" rel="noreferrer noopener">University of California, Davis</a> have created the most detailed genome sequence of the pistachio to date. </p>



<p>The work opens the door to developing better pistachio varieties that are potentially more nutritious and resilient to climate change. </p>



<p>Alongside the genome, the team also charted the full development cycle of the <a href="https://www.earth.com/news/eating-nuts-every-day-does-not-cause-weight-gain-but-it-does-improve-health/" target="_blank" rel="noreferrer noopener">nut</a>, offering insights that could help farmers grow and harvest their crops more efficiently and sustainably.</p>



<h2 class="wp-block-heading" id="h-a-sharper-view-of-pistachio-genetics">A sharper view of pistachio genetics</h2>



<p>While previous studies have sequenced pistachio DNA, the new genetic map stands apart for its depth and precision.</p>



<p>“The improvement in accuracy of the new reference <a href="https://www.earth.com/news/how-does-genome-size-impact-evolutionary-success/" target="_blank" rel="noreferrer noopener">genome</a> is like going from a hand-drawn map of a landscape to a satellite image from Google Earth,” said study co-author J. Grey Monroe, an assistant professor with the Department of Plant Sciences.</p>



<p>The team focused on the Kerman cultivar, the most widely grown pistachio variety in California. By zeroing in on this standard, the researchers made their findings directly relevant to commercial growers.</p>



<h2 class="wp-block-heading" id="h-climate-change-threatens-cold-loving-trees">Climate change threatens cold-loving trees</h2>



<p><a href="https://www.earth.com/image/springtime-brings-greenery-and-dust-to-turkmenistan/" target="_blank" rel="noreferrer noopener">Pistachio trees</a> are famously tough. They handle drought and salty soil better than many crops. But they also have a weakness: they need cold winters to flower and produce nuts. </p>



<p>Warmer winters in recent years, along with less fog in California’s Central Valley, have disrupted that process and reduced yields.</p>



<p>Since pistachio trees can live and produce nuts for up to 50 years, any decision about what to plant carries long-term consequences. With climate patterns shifting, growers are understandably worried about the future of their <a href="https://www.earth.com/news/megafire-smoke-has-long-lasting-impacts-on-orchard-trees/" target="_blank" rel="noreferrer noopener">orchards</a>.</p>



<p>This is where the new genome map could help. It gives plant breeders a powerful tool to create new pistachio varieties that can adapt to warmer conditions while maintaining - or even improving - nut quality.</p>



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



<p>The research didn’t stop at the genetic level. The team also tracked how pistachios develop over time, identifying four key stages from flowering to harvest. This includes when the shell hardens and when the kernel inside grows.</p>



<p>“Knowing how the nut changes through development will help farmers make better decisions, like when to water their trees, leading to more sustainable pistachio production,” said study co-author Bárbara Blanco-Ulate.</p>



<p>This information could also help farmers better time their harvests and reduce losses from insects or fungal infections. </p>



<p>Beyond the physical stages, the researchers also studied the genetic activity at each step, offering a full picture of how the nut grows and changes.</p>



<h2 class="wp-block-heading" id="h-pistachios-with-enhanced-health-benefits">Pistachios with enhanced health benefits </h2>



<p>Pistachios are known for being a <a href="https://www.earth.com/news/eating-pistachios-daily-proven-to-boost-eyes-vision-and-overall-health/" target="_blank" rel="noreferrer noopener">healthy snack</a> packed with protein and unsaturated fats. Now, researchers have pinpointed the specific genes and molecular pathways responsible for these benefits.</p>



<p>“We’re getting information about how all these nutritional characteristics are gained in pistachios and how we can improve that from a management perspective,” said Blanco-Ulate.&nbsp;</p>



<p>Understanding how nutrients build up in the nut over time could help producers fine-tune growing practices or even develop pistachios with enhanced health benefits and longer shelf life.</p>



<h2 class="wp-block-heading" id="h-a-future-rooted-in-science">A future rooted in science</h2>



<p>With this new genetic map and a clearer picture of how pistachios grow, researchers and farmers are better equipped to face the challenges of tomorrow. </p>



<p>Whether it’s adapting to climate change or improving nut quality, California’s pistachio industry now has powerful new tools to work with - one gene at a time.</p>



<p>The implications go beyond scientific curiosity. As climate pressures intensify and global demand for nutritious, sustainably grown food rises, advances like these can help secure the future of an industry that supports thousands of jobs and contributes billions to the economy. </p>



<p>From breeding better trees to optimizing harvest times, science is now firmly planted at the root of pistachio production.</p>

How pistachio DNA is shaping the future of farming

California grows nearly all of the nation’s pistachios, producing 99%...

<p>In the face of climate change, forests have become more than green landscapes. They regulate temperatures, purify air and water, protect soil, and support biodiversity. </p>



<p>Forests also absorb carbon dioxide from the atmosphere and store it in trees and soil, helping to reduce global warming.</p>



<p>Oceans do the same, but forests offer a land-based solution, one that we can manage directly. The idea of planting more trees has taken hold worldwide. But the story doesn’t end there.</p>



<p>Not all <a href="https://www.earth.com/news/trees-are-losing-the-battle-against-climate-change/" target="_blank" rel="noreferrer noopener">trees</a> offer the same benefits. Some grow quickly, others slowly. Some survive tough climates, others do well only in ideal conditions. </p>



<p>The challenge for forest managers is figuring out which trees will trap the most carbon where they are planted.</p>



<p>The answer lies in matching tree traits with the land on which they grow.</p>



<h2 class="wp-block-heading" id="h-a-global-study-seeks-answers">A global study seeks answers</h2>



<p>To explore this issue, researchers from&nbsp;<a href="https://www.inrae.fr/en" target="_blank" rel="noreferrer noopener">INRAE</a>&nbsp;and&nbsp;<a href="https://www.agro-bordeaux.fr/" target="_blank" rel="noreferrer noopener">Bordeaux Sciences Agro</a>&nbsp;teamed up with global partners. The project brought together the&nbsp;French National Forest Office (<a href="https://www.onf.fr/" target="_blank" rel="noreferrer noopener">ONF</a>)&nbsp;and the&nbsp;French National Center for Private Forest Ownership (<a href="https://www.cnpf.fr/" target="_blank" rel="noreferrer noopener">CNPF</a>).</p>



<p>Together, they studied 223 tree species in 160 forest sites around the world. These included locations in Western Europe, the United States, Brazil, Ethiopia, Cameroon, and South-East Asia.</p>



<p>Each species was chosen to represent one of the world’s major forest biomes. The team focused on functional traits - specific characteristics that affect how a <a href="https://www.earth.com/news/tree-crops-a-path-to-feeding-the-world-and-saving-the-planet/" target="_blank" rel="noreferrer noopener">tree</a> grows, uses water and nutrients, and stores carbon. </p>



<p>Their goal was simple yet ambitious: to identify which traits lead to better growth and carbon capture in real-world forest conditions.</p>



<h2 class="wp-block-heading" id="h-old-beliefs-on-carbon-and-trees">Old beliefs on carbon and trees</h2>



<p>For a long time, scientists believed that trees with acquisitive traits grew the fastest. These trees absorb resources like sunlight, water, and soil nutrients very efficiently. In controlled experiments, such as those in greenhouses, they outperform other trees in height, leaf size, and biomass.</p>



<p>Examples include maples, poplars, English oaks, and sessile oaks. These species have large leaves and long roots that gather nutrients quickly. Their leaves also contain large amounts of nitrogen, which supports rapid photosynthesis. All these features make them ideal candidates for storing carbon - at least on paper.</p>



<p>On the other side are conservative species. These trees invest less energy in fast growth. Instead, they survive by conserving internal resources like water and energy. Fir trees, downy oaks, and holm oaks fit this model. They usually grow more slowly but are better at handling environmental stress.</p>



<h2 class="wp-block-heading" id="h-a-surprise-from-real-forests">A surprise from real forests</h2>



<p>When the team took their research into real forests, their findings turned the old beliefs upside down. Under natural conditions in boreal and temperate zones, conservative <a href="https://www.earth.com/news/future-forests-which-tree-species-can-survive-climate-change/" target="_blank" rel="noreferrer noopener">tree species</a> actually stored more carbon and grew faster than acquisitive ones. That may seem surprising, but the explanation lies in how these forests function.</p>



<p>Boreal and temperate forests often have cold climates, poor soil, or both. In such settings, being efficient with internal resources becomes more important than fast nutrient absorption.</p>



<p>In tropical forests, the story changes again. These regions have ideal growing conditions - warm temperatures and high rainfall. Here, acquisitive and conservative species grow at similar speeds. Neither group holds a strong advantage.</p>



<h2 class="wp-block-heading" id="h-matching-trees-with-their-environment">Matching trees with their environment</h2>



<p>The biggest lesson from this research is that one size does not fit all. You cannot plant fast-growing trees everywhere and expect success. Tree performance depends heavily on local soil and climate conditions.</p>



<p>In rich, well-watered environments, acquisitive species like maples and poplars will outperform others. They can absorb nutrients quickly and convert them into biomass, storing more carbon. But in dry, cold, or nutrient-poor conditions, conservative species shine. Oaks, firs, and pines may grow more slowly, but they store more carbon over time because they survive and grow when others cannot.</p>



<p>The study highlights the need for precision in reforestation efforts. Forest managers must consider each site’s unique conditions. Planting the right <a href="https://www.earth.com/news/trees-have-an-amazing-ability-to-adapt-to-new-climates/" target="_blank" rel="noreferrer noopener">tree</a> in the right place is far more effective than planting the same fast-growers everywhere.</p>



<h2 class="wp-block-heading" id="h-choosing-trees-for-better-carbon-impact">Choosing trees for better carbon impact</h2>



<p>This new understanding gives forest managers a sharper tool in the fight against climate change. They can now look beyond growth speed and consider how a <a href="https://www.earth.com/news/trees-are-relocating-in-a-race-against-global-warming/" target="_blank" rel="noreferrer noopener">tree’s traits</a> interact with its environment. This leads to smarter choices and healthier forests.</p>



<p>Climate action often demands quick results. But nature does not always work that way. Sometimes the slow-growing, stress-tolerant tree is the one that captures the most carbon in the long run. </p>



<p>With this knowledge, reforestation can become both more effective and more sustainable.</p>

Slow and steady tree growth wins the race for carbon capture

In the face of climate change, forests have become more...

<p>The hidden interiors of Uranus and Neptune have long puzzled scientists who try to understand how these distant ice giants formed and evolved. </p>



<p>Past proposals included the possibility of diamond rain falling through their cores or super-ionic water lurking beneath their bluish exteriors. </p>



<p>Each idea sparked interest, yet questions persisted about the unusual nature of these planets’ <a href="https://www.earth.com/news/earths-magnetic-field-is-shifting-and-putting-navigation-at-risk/" target="_blank" rel="noreferrer noopener">magnetic fields</a> and internal structures.</p>



<p>Recent work proposes a different view. After many years of study and advanced computer simulations, a new theory suggests that materials in Uranus and Neptune could separate into layers as pressures rise. </p>



<p>Burkhard Militzer, a professor of Earth and planetary science at the <a href="https://www.berkeley.edu/" target="_blank" rel="noreferrer noopener">University of California, Berkeley</a>, has put forth a model that challenges older notions and draws on the principles of immiscibility - when substances refuse to mix, like oil and water.</p>



<h2 class="wp-block-heading" id="h-layered-interiors-and-magnetic-fields">Layered interiors and magnetic fields</h2>



<p>Militzer believes that under the extreme conditions found in the deep layers of these planets, ingredients such as water (H₂O), methane (CH₄), and ammonia (NH₃) behave in unexpected ways. </p>



<p>“We now have, I would say, a good theory about why Uranus and Neptune have really different fields, and it's very different from Earth, Jupiter, and Saturn,” Militzer explained. </p>



<p>“It's like oil and water, except the hydrogen-rich layer goes on top, and the heavier material stays below.”</p>



<p>His findings also align with magnetic field readings collected by <a href="https://www.earth.com/news/decades-after-voyager-2-flew-by-uranus-we-finally-know-what-it-saw/" target="_blank" rel="noreferrer noopener">NASA’s Voyager 2</a> in the 1980s. Instead of a tidy, dipolar field like Earth’s, Uranus and Neptune show disorganized magnetic fields. </p>



<p>Militzer’s model proposes that the water-rich layer under the atmospheres can move enough to create these irregular fields, while the deeper hydrocarbon-rich layer remains stable and resists mixing.</p>



<h2 class="wp-block-heading" id="h-extreme-pressures-and-new-simulations">Extreme pressures and new simulations</h2>



<p>Militzer used computer models to simulate conditions at pressures reaching 3.4 million times Earth’s atmospheric pressure and temperatures around 8,000°F. </p>



<p>A decade ago, he ran calculations with 100 atoms but could not confirm layered separation. </p>



<p>Recently, he expanded those simulations to 540 atoms, leveraging machine learning and stronger computing power. </p>



<p>“One day, I looked at the model, and the water had separated from the carbon and nitrogen,” he said. “What I couldn't do 10 years ago was now happening.”</p>



<p>As depth increases, hydrogen is squeezed out of <a href="https://www.earth.com/news/discovery-about-jupiters-clouds-not-ammonia-ice-leaves-astronomers-astonished/" target="_blank" rel="noreferrer noopener">methane and ammonia</a>, creating a carbon-nitrogen-hydrogen fluid that sits below a water-rich zone. </p>



<p>According to Militzer’s gravity calculations, this layering matches readings taken by Voyager 2 nearly 40 years ago. </p>



<p>Beneath Uranus’ 3,000-mile-thick atmosphere, the model points to a 5,000-mile-thick layer of water-rich fluid. A <a href="https://www.earth.com/news/uranus-is-more-gassy-less-icy-than-we-ever-imagined/" target="_blank" rel="noreferrer noopener">hydrocarbon-rich layer</a> of similar thickness lies underneath, ending at a rocky core roughly the size of Mercury. </p>



<p>Neptune follows the same layout but has a thinner atmosphere and a slightly larger rocky core, about the size of Mars.</p>



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



<p>Ice giants comparable to Uranus and Neptune appear to be common in other star systems, where they are often referred to as <a href="https://www.earth.com/news/neptune-like-exoplanets-atmospheres-interesting-earth-size-neighbors/" target="_blank" rel="noreferrer noopener">sub-Neptune exoplanets</a>. </p>



<p>“If other star systems have similar compositions to ours, ice giants around those stars could well have <a href="https://www.earth.com/news/miranda-uranus-moon-may-have-hidden-ocean-possibly-extraterrestrial-life/" target="_blank" rel="noreferrer noopener">similar internal structures</a>,” Militzer noted. </p>



<p>He sees this model as a way to explain varied planetary magnetic fields beyond our solar neighborhood.</p>



<p>Militzer aims to collaborate with experimental physicists to test these concepts in the lab. </p>



<p>By recreating the extreme conditions of water, methane, and ammonia in the right proportions, researchers could discover whether layers form on their own. </p>



<p>He believes this work could confirm the immiscible behavior that sets the stage for the stability of these deep <a href="https://www.earth.com/news/three-new-moons-discovered-around-neptune-and-uranus/" target="_blank" rel="noreferrer noopener">planetary zones</a>.</p>



<h2 class="wp-block-heading" id="h-diamond-rain-is-cool-but-not-important">Diamond rain is cool, but not important</h2>



<p>Talk of diamond rain and super-ionic water once captured imaginations, but Militzer’s simulations question those ideas. </p>



<p>“If you ask my colleagues, ‘What do you think explains the fields of Uranus and Neptune?’ they may say, ‘Well, maybe it’s this diamond rain, but maybe it’s this water property which we call super-ionic,’” he said. </p>



<p>“From my perspective, this is not plausible. But if we have this separation into two separate layers, that should explain it.”</p>



<p>Upcoming space missions might shed more light on the issue. A proposed NASA <a href="https://www.earth.com/news/new-photos-of-uranus-from-hubble-and-new-horizons/" target="_blank" rel="noreferrer noopener">trip to Uranus</a> could carry instruments to measure the planet’s vibrations through Doppler imaging. </p>



<p>A non-mixing interior would jiggle in different ways than one with full convection. Militzer plans to use his computational model to predict those vibrations, offering a fresh way to confirm or refute his layered theory.</p>



<h2 class="wp-block-heading" id="h-what-s-next-for-uranus-and-neptune">What's next for Uranus and Neptune?</h2>



<p>This perspective on Uranus and Neptune adds a personal dimension to the centuries-long quest to understand our solar system. </p>



<p>Each discovery builds on a chain of data, from telescopes to spacecraft, and now advanced simulations. </p>



<p>Militzer’s decade of effort offers an approach that explains how water and hydrocarbon fluids might settle into distinct bands deep inside these ice giants.</p>



<p>His findings suggest a layered format that explains their odd magnetic fields and gravitational measurements. </p>



<p>The model supplies a framework for designing experiments, planning future probes, and even exploring how exoplanets might evolve. </p>



<p>By identifying the presence of two immiscible layers - one water-rich and one made of highly compressed hydrocarbons - this theory marks another step toward unraveling Uranus and Neptune’s secrets, one simulation at a time.</p>



<p>The full study was published in the journal <a href="http://dx.doi.org/10.1073/pnas.2403981121" target="_blank" rel="noreferrer noopener"><em>Proceedings of the National Academy of Sciences</em></a>.</p>

Claim: Uranus and Neptune have oceans that are 5000 miles deep

The hidden interiors of Uranus and Neptune have long puzzled...

<p>Out of all the planets in our solar system beyond Earth, most consider Saturn's beauty to be the most spectacular, with a set of rings that have inspired curiosity for hundreds of years. </p>



<p>In the 17th century, Italian astronomer Galileo Galilei described this distant world as having "ears," showing how limited his view was at the time. </p>



<p>Even with basic tools, he sensed something unusual about the planet’s appearance, although he could not fully explain it.</p>



<h2 class="wp-block-heading" id="h-beauty-and-awe-of-saturn-s-rings">Beauty and awe of Saturn's rings</h2>



<p>Modern telescopes and worldwide observatories have transformed our <a href="https://www.earth.com/news/massive-energy-imbalance-discovered-on-saturn/" target="_blank" rel="noreferrer noopener">understanding of Saturn</a>. They reveal swirling collections of ice and rocks orbiting the massive planet in broad arcs that we call rings. </p>



<p>These ribbons of debris are more than a mere celestial decoration for us humans to admire; they shed light on the gravitational forces at work in our solar system.</p>



<p>By studying Saturn's rings, astronomers gain a better understanding of how cosmic particles behave when bound by gravity, and why their appearance changes when viewed from Earth. </p>



<p>Jonah Peter, a doctoral student at Harvard-Smithsonian Center for Astrophysics (<a href="https://www.cfa.harvard.edu/" target="_blank" rel="noreferrer noopener">CfA</a>), has focused on how Saturn’s moons affect the <a href="https://www.earth.com/news/new-image-of-saturn-and-its-ring-spokes-from-the-hubble-space-telescope/" target="_blank" rel="noreferrer noopener">ring environment</a>.</p>



<p>His work connects the motions of this ring material to the broader story of our cosmic neighborhood, all of which is driven by a process known as orbital mechanics, or celestial mechanics. </p>



<h2 class="wp-block-heading" id="h-mechanics-of-orbiting-planets-the-basics">Mechanics of orbiting planets - the basics</h2>



<p>Orbital mechanics describes how bodies move under the pull of gravity. Planets circle the Sun, moons circle planets, and satellites stay in orbit around Earth. </p>



<p>These paths depend on factors like velocity and orbital shape, all of which keep objects traveling in predictable loops.</p>



<p>Saturn’s tilt plays a role in how we see the rings. As the planet continues on its journey, our viewpoint changes over time. </p>



<p>In some phases, the rings show off their full width. In others, they line up edge-on, turning into a thin band that seems ready to vanish.</p>



<h2 class="wp-block-heading" id="h-how-saturn-s-rings-will-disappear">How Saturn's rings will disappear</h2>



<p>A striking event called a "ring plane crossing" will occur on March 23, 2025. The rings will appear to have completely vanished because their thin edges will be aimed at Earth.</p>



<p>This alignment happens when Saturn’s tilt and location match up so that we no longer see the bright swath of particles head-on.<br><br>Once the rings vanish from easy sight in March 2025, Saturn will look like a pale yellow sphere through most telescopes. A subtle line may be visible around the planet’s middle, but only through the most powerful telescopes.</p>

<p>Some enthusiasts might miss the typical glow, yet there is a certain thrill in waiting for that grand display to reappear.</p>



<p>As Earth and Saturn shift positions, the rings will come back into full view around November 2025. The planet’s looping debris will stand out again, along with glimpses of its many moons. </p>



<p><a href="https://www.earth.com/news/megastorms-on-saturn-are-larger-than-the-earth-and-last-for-hundreds-of-years/" target="_blank" rel="noreferrer noopener">This recurring pattern</a> reminds observers that our perspective can change, even when Saturn itself remains the same majestic world it has always been.</p>



<h2 class="wp-block-heading" id="h-composition-and-structure-of-saturn-s-rings">Composition and structure of Saturn's rings</h2>



<p>The rings are <a href="https://www.earth.com/news/saturns-rings-may-have-formed-after-two-icy-moons-collided/" target="_blank" rel="noreferrer noopener">divided into sections</a> called the A, B, and C rings, plus a few fainter ones labeled D, E, F, and G. Between the A and B rings lies the Cassini Division, measuring around 2,982 miles wide. </p>



<p>Scientists note that spaces like this can form when orbital motions and gravitational tugs clear out certain pathways.</p>



<p>These rings are not solid sheets. They're made of pieces that range from dust-size grains to lumps as large as buses. </p>



<p>Some researchers think the rings sprang from a moon ripped apart by Saturn’s gravity. Others propose that leftover material from the planet’s formation helped craft <a href="https://www.earth.com/news/we-now-know-the-age-of-saturns-rings-and-the-number-might-surprise-you/" target="_blank" rel="noreferrer noopener">these looping bands</a> more than four billion years ago.</p>



<h2 class="wp-block-heading" id="h-moons-and-their-gravitational-pull">Moons and their gravitational pull</h2>



<p>Saturn hosts <a href="https://www.earth.com/news/saturn-now-leads-the-solar-system-moon-race-with-145/" target="_blank" rel="noreferrer noopener">at least 145 moons</a>. Some are called shepherd moons, and they drift near the ring edges. </p>



<p>Their gravity holds ring particles in place, preventing them from scattering too far in one direction or another. This process helps the rings maintain their recognizable gaps and bands.</p>



<p>Beyond those shepherds, Saturn’s system includes larger bodies that have unique properties. <a href="https://www.earth.com/news/saturns-moon-titan-has-shorelines-shaped-by-waves/" target="_blank" rel="noreferrer noopener">The biggest, Titan</a>, is a place of ongoing study. It has an atmosphere mostly made of nitrogen. </p>



<p>Scientists have also measured a magnetic field around Titan that, while weaker than Jupiter’s, surpasses Earth’s field in relative strength.</p>



<h2 class="wp-block-heading" id="h-saturn-s-mystery-and-majesty">Saturn's mystery and majesty</h2>



<p>Galileo’s old remark about Saturn’s "ears" underscores how far we have come. Early astronomers had limited tools, yet they still glimpsed something remarkable. </p>



<p>Modern instruments add detail, but the sense of wonder remains. Saturn shows how our solar system is filled with surprises that motivate fresh discoveries.</p>



<p>As amateurs and experts keep pointing their lenses skyward, they continue to find reasons to appreciate this planet’s evolving appearance. </p>



<p>The rings may fade from view temporarily, but people know they will return. Each phase allows us to learn a little more about how cosmic objects behave and how life might emerge under new conditions.</p>

Saturn's mesmerizing rings are disappearing this weekend

Out of all the planets in our solar system beyond...

<p>In the scorching deserts of Namibia, Oman, and Saudi Arabia, scientists have discovered a curious feature in the rocks - thin, orderly tubes running through marble and limestone, possibly created by ancient microbes.</p>



<p>These structures don’t resemble any known geological process, and researchers believe they may be the work of an unidentified form of microbial life. If confirmed, this discovery could reshape our understanding of <a href="https://www.earth.com/news/evolution-itself-found-to-be-evolving-as-life-constantly-learns-to-adapt/" target="_blank" rel="noreferrer noopener">how life adapts</a> to extreme environments.</p>



<p>The investigation began with scientists from <a href="https://www.uni-mainz.de/en/" target="_blank" rel="noreferrer noopener">Johannes Gutenberg University Mainz</a> (JGU), who noticed the phenomenon during fieldwork in Namibia. Later analysis confirmed the presence of biological material inside the rocks.</p>



<p>“We were surprised because these tubes are clearly not the result of a geological process,” said Professor Cees Passchier of JGU, who first spotted the strange formations. “We don’t currently know whether this is a life form that has become extinct or is still alive somewhere.”</p>



<h2 class="wp-block-heading" id="h-a-puzzle-millions-of-years-in-the-making">A puzzle millions of years in the making</h2>



<p>The discovery was made in samples of ancient marble that formed when carbonate deposits were subjected to pressure and heat over hundreds of millions of years. The tiny micro-burrows line the edges of fractures inside the rock.</p>



<p>“We noticed strange structures in this marble that were not the result of geological events,” remarked Passchier.</p>



<p>The tubes are no wider than half a millimeter and can stretch up to three centimeters in length. They run parallel to each other in long bands, some spanning up to ten meters.</p>



<h2 class="wp-block-heading" id="h-highly-organized-patterns-in-the-rocks">Highly organized patterns in the rocks</h2>



<p>Unlike erosion patterns that are typically left behind by wind or water, these formations appear highly organized, and hint at a biological origin. In some places, crusts of calcrete had formed around the edges of the bands, adding to their uniqueness.</p>



<p>The phenomenon was first observed in Namibia 15 years ago, but more recent samples have shown similar features in rocks from Oman and Saudi Arabia. The tubes in Oman appeared in limestone, while those in Saudi Arabia were found in marble.</p>



<p>In every case, the tunnels were filled not with empty space, but with fine calcium carbonate powder - suggesting that the <a href="https://www.earth.com/news/microbes-hitch-rides-on-winds-across-continents/" target="_blank" rel="noreferrer noopener">microorganisms</a> may have extracted nutrients from the rock and left the residue behind.</p>



<h2 class="wp-block-heading" id="h-microbes-that-thrive-in-the-dark">Microbes that thrive in the dark</h2>



<p>The research team from Mainz University collaborated with Dr. Trudy Wassenaar, head of Molecular Microbiology and Genomics Consultants, to explore the biological aspects of the formations. </p>



<p>They suspect the tubes were created by endolithic microbes - <a href="https://www.earth.com/news/organisms-called-protosterol-biota-lived-1-6-billion-years-ago/" target="_blank" rel="noreferrer noopener">organisms</a> that live inside rock.</p>



<p>These types of microbes, including <a href="https://www.earth.com/news/bacteria-pass-down-memories-to-future-generations/" target="_blank" rel="noreferrer noopener">bacteria</a>, <a href="https://www.earth.com/news/fungi-can-think-and-make-smart-decisions-without-a-brain/" target="_blank" rel="noreferrer noopener">fungi</a>, and lichens, are known to survive in some of the world’s harshest environments.</p>



<p>But there’s a twist: the structures are likely one or two million years old, and may have formed during a time when the desert climate was more humid. And while biological traces were found, the structures were too old to preserve any DNA or protein that could help identify the organism.</p>



<p>“What is so exciting about our discovery is that we do not know which endolithic microorganism this is," said Passchier. "Is it a known form of life or a completely unknown organism?”</p>



<p>The tubes are located deep inside the rock, far from any light source, meaning the life form must have existed without sunlight.</p>



<h2 class="wp-block-heading" id="h-rock-microbes-and-earth-s-carbon-balance">Rock microbes and Earth's carbon balance</h2>



<p>While the exact identity of the tunnel-making organism remains unknown, the implications could be far-reaching.</p>



<p>Microbial life that interacts with rock can influence the global carbon cycle by breaking down minerals and releasing carbon.</p>



<p>Professor Passchier said that while we do not know whether this form of life still exists, it could be important for the global carbon cycle. "It is therefore essential that the scientific community becomes aware of it."</p>



<p>If these microorganisms played a role in transforming calcium carbonate, they might have contributed to the Earth’s CO₂ balance in ways we don’t yet understand. </p>



<p>Their potential influence on long-term climate regulation highlights the need for further investigation.</p>



<p>For now, the mystery remains buried in the rock. But with further study, these tiny tunnels might one day tell a much bigger story.</p>



<p>The full study was published in the journal <em><a href="https://www.tandfonline.com/doi/full/10.1080/01490451.2025.2467417" target="_blank" rel="noreferrer noopener">Geomicrobiology Journal</a></em>.</p>

Unknown life forms discovered living in marble and limestone rocks

In the scorching deserts of Namibia, Oman, and Saudi Arabia,...

<p>Cannabidiol (CBD) is popularly used for its painkilling, anti-inflammatory, and neuroprotective effects. It has been used to treat illnesses like epilepsy and multiple sclerosis.</p>



<p>But there has been one key limitation preventing it from being used to its full potential - CBD does not dissolve easily in water, so the body has trouble absorbing it efficiently.</p>



<p>Researchers at the <a href="https://www.unisa.edu.au/" target="_blank" rel="noreferrer noopener">University of South Australia</a> have created a new method to address this issue.</p>



<p>By forming a phospholipid complex using a fat-based molecule that contains phosphorus, scientists have greatly enhanced CBD’s solubility and absorption in the human body.</p>



<h2 class="wp-block-heading" id="h-enhancing-cbd-s-bioavailability">Enhancing CBD's bioavailability </h2>



<p>Today, only a fraction of orally consumed CBD is absorbed into the bloodstream. This restricts its efficacy, and necessitates the use of increased doses to produce therapeutic effects.</p>



<p>Over the years, scientists have tried different methods to enhance CBD’s bioavailability, including using synthetic forms, self-emulsifying systems, and gelatine-based encapsulation. These attempts have only yielded minimal gains.</p>



<p>In the new study, researchers experimented to find the optimal composition of <a href="https://www.earth.com/news/phospholipids-tiny-bubbles-that-may-have-been-earths-first-cells/" target="_blank" rel="noreferrer noopener">phospholipids</a> to create nanosized CBD-PLC (phospholipid complex) particles.</p>



<p>The CBD-phospholipid complex particles enhanced dissolution from 0% (without the CBD-PLC particles) to 67.1% after only three hours. This tremendous improvement in drug release guarantees a more uniform and potent treatment for patients.</p>



<h2 class="wp-block-heading" id="h-a-more-stable-treatment-option">A more stable treatment option</h2>



<p>In addition to better solubility, the phospholipid complex demonstrated a 32.7% increase in permeability during cellular uptake studies. </p>



<p>This means more of the drug can pass through the intestinal wall, leading to greater absorption and improved therapeutic effects.</p>



<p>Traditional formulations degrade when exposed to heat, light, or oxygen, which reduces their potency over time. However, testing over 12 months showed that the new CBD-PLC formulation maintained its performance under various storage conditions. </p>



<p>This makes it a more stable and reliable option for pharmaceutical use.</p>



<h2 class="wp-block-heading" id="h-implications-for-cbd-based-therapies">Implications for CBD-based therapies</h2>



<p>“Improved bioavailability means that lower doses can achieve the same therapeutic effect, potentially reducing <a href="https://www.earth.com/news/prenatal-exposure-to-cannabis-linked-to-health-risks-later-in-life/" target="_blank" rel="noreferrer noopener">side effects</a> and making treatment more cost effective,” said study first author Thabata Muta, a PhD candidate at the University of South Australia.</p>



<p>This discovery could go beyond CBD. Many drugs with poor water solubility face similar challenges. </p>



<p>The phospholipid complex approach may provide a blueprint for enhancing the absorption of other medications as well.</p>



<h2 class="wp-block-heading" id="h-the-road-to-real-world-impact">The road to real-world impact</h2>



<p>With the international CBD market projected to expand from $7.59 billion in 2023 to $202.45 billion by 2032, this innovation comes at an opportune time. </p>



<p>By overcoming a key challenge in CBD treatment, this technology could make cannabinoid-based therapy more accessible, affordable, and effective for millions worldwide.</p>



<p>The team is currently looking into commercialization prospects and preparing to conduct clinical trials that will confirm the recipe.</p>



<h2 class="wp-block-heading" id="h-safer-cbd-based-medications">Safer CBD-based medications</h2>



<p>CBD’s low water solubility has been a long-standing problem for scientists and <a href="https://www.earth.com/news/machine-learning-could-revolutionize-drug-discovery/" target="_blank" rel="noreferrer noopener">drug</a> developers.</p>



<p>Nanoemulsions, liposomal carriers, and solid dispersions are some of the techniques that have been tried in order to increase the bioavailability of CBD.</p>



<p>Most of these techniques use complicated manufacturing processes, involve the inclusion of extra stabilizing agents, or don't deliver consistent absorption rates.</p>



<p>The phospholipid complex (CBD-PLC) of the UniSA research group is a more hopeful option. </p>



<p>By naturally blending in with biological membranes, phospholipids aid in more efficient CBD transport by the digestive tract. This would render artificial surfactants obsolete, and so CBD-based medications could be safer and more tolerable in the long term.</p>



<h2 class="wp-block-heading" id="h-potential-pharmaceutical-applications">Potential pharmaceutical applications </h2>



<p>In addition to enhancing CBD for general consumer applications, this method may have a seminal role in pharmaceutical applications.</p>



<p>Patients dependent on CBD-based medication for <a href="https://www.earth.com/news/medicinal-cannabis-reduces-epileptic-seizures-by-86-percent/" target="_blank" rel="noreferrer noopener">epilepsy</a>, multiple sclerosis, and <a href="https://www.earth.com/news/cbd-can-help-ease-chronic-pain-anxiety-and-mood-disorders/" target="_blank" rel="noreferrer noopener">pain</a> treatment are frequently exposed to unpredictable therapeutic responses because of the variability of absorption.</p>



<p>The improved solubility and stability of CBD-PLC might allow dosing to be more exact which, in turn, may decrease variability of drug action and side effects.</p>



<p>Pharmaceutical companies can also utilize this technology to create advanced cannabinoid medicines with better delivery systems. </p>



<p>This may open the way for better pain relief, neurological therapies, and potentially even the use of CBD in mental health disorders like anxiety and PTSD.</p>



<p>In addition, by addressing CBD’s issues with bioavailability, this technology may help lower the dosage requirements, ultimately leading to safer and more economical treatments for patients.</p>

Revolutionizing CBD treatment for epilepsy and multiple sclerosis

Cannabidiol (CBD) is popularly used for its painkilling, anti-inflammatory, and...

<p>Every great civilization began by a river. Empires rose where water flowed freely. Today, we live in a world more connected than ever, yet 2.2 billion people still lack access to safe water. </p>



<p>Each year on March 22, World Water Day reminds us that the water crisis is not a distant issue - it is already here, and it is growing. </p>



<p>Since 1993, this <a href="https://www.un.org/en/" target="_blank" rel="noreferrer noopener">United Nations</a> observance has emphasized the critical role of freshwater, the lifeblood of our planet.</p>



<h2 class="wp-block-heading" id="h-themes-of-world-water-day">Themes of World Water Day </h2>



<p>Each year, UN-Water selects a theme to reflect the world’s most pressing <a href="https://www.earth.com/news/wave-ripples-discovered-mars-surface-indicate-liquid-water-present-4-billion-years-ago/" target="_blank" rel="noreferrer noopener">water</a> concern. </p>



<p>In 2023, we were asked to speed up progress with "Accelerating Change." In <a href="https://www.earth.com/news/world-water-day-a-focus-on-prosperity-and-peace/" target="_blank" rel="noreferrer noopener">2024</a>, we saw water as a bridge, not a boundary, with "Leveraging Water for Peace." </p>



<p>In 2025, the world will turn its focus to "Glacier Preservation," as the silent towers of ice that hold our freshwater reserves are now vanishing at alarming speed.</p>



<p>Glaciers store nearly 70% of the world’s freshwater. They feed rivers, support agriculture, and cool the planet. But they are melting faster than ever. In many parts of the world, these icy reserves are shrinking to record lows. Their disappearance threatens billions of lives.</p>



<p>​According to reports from&nbsp;<a href="https://www.unesco.org/en/days/world-glaciers" target="_blank" rel="noreferrer noopener">UNESCO</a>&nbsp;and the&nbsp;<a href="https://public.wmo.int/en" target="_blank" rel="noreferrer noopener">World Meteorological Organization</a>, many tropical glaciers may vanish completely by the end of this century.&nbsp;This loss signifies more than just rising sea levels; it threatens the primary freshwater sources for millions, especially during dry seasons.</p>



<h2 class="wp-block-heading" id="h-why-glaciers-matter-to-everyone">Why glaciers matter to everyone</h2>



<p>Even if you’re far from the Himalayas or Andes, melting glaciers still affect you. They influence river flow, alter ocean currents, and shape weather patterns. Their decline impacts agriculture, drinking water, wildlife, and energy resources across the globe.</p>



<p>Glacial retreat also destabilizes the surrounding land. Floods, droughts, and landslides become more frequent. In countries like Peru and Bhutan, entire communities face relocation as their water sources dry up.</p>



<p>Glaciers serve as climate indicators. When they melt too fast, they show us something is deeply wrong. </p>



<h2 class="wp-block-heading" id="h-from-climate-crisis-to-water-crisis">From climate crisis to water crisis</h2>



<p>Climate change and the water crisis are deeply intertwined. Rising global temperatures accelerate glacier melt and destabilize freshwater sources, creating scarcity and fueling conflict.</p>



<p>The 2024 theme, "Leveraging Water for Peace," recognized that water stress can spark geopolitical tensions. Rivers that cross borders often become points of disagreement. </p>



<p>But they can also become grounds for cooperation. Joint management and fair sharing of water resources can build trust and prevent conflict.</p>



<p>With glacier-fed rivers drying up, disputes will likely rise. World Water Day 2025 aims to make nations act before tensions escalate.</p>



<h2 class="wp-block-heading" id="h-global-goals-on-world-water-day">Global goals on World Water Day </h2>



<p>World Water Day supports Sustainable Development <a href="https://sdgs.un.org/goals/goal6" target="_blank" rel="noreferrer noopener">Goal 6</a>: water and sanitation for all by 2030. Glaciers are central to that mission. Preserving them isn’t just about protecting nature - it’s about protecting human rights.</p>



<p>Without consistent water, schools can’t operate, hospitals can’t function, and economies collapse. Women and children often bear the burden, walking miles for a daily bucket of <a href="https://www.earth.com/news/water-arrived-on-earth-gradually-not-in-one-big-event/" target="_blank" rel="noreferrer noopener">water</a>. In mountain communities, where glacier melt is the main supply, that burden grows heavier with each passing year.</p>



<p>Preserving glaciers helps us ensure future generations are not born into thirst. It means infrastructure today must account for shrinking ice tomorrow.</p>



<h2 class="wp-block-heading" id="h-take-action-on-world-water-day">Take action on World Water Day </h2>



<p>World Water Day doesn’t just ask governments to act. It invites everyone to participate. From households to corporations, everyone has a role in managing <a href="https://www.earth.com/news/water-might-have-formed-long-before-galaxies/" target="_blank" rel="noreferrer noopener">water</a> wisely.</p>



<p>It starts with understanding the issue. Education remains a powerful tool. People need to know where their water comes from, how it is used, and how it is wasted. Campaigns, school programs, and media outreach matter more than ever.</p>



<p>On a policy level, governments must invest in glacier monitoring, support clean energy to slow climate change, and ensure mountain communities are protected. Cross-border cooperation will also be essential in managing shared water sources.</p>



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



<p>Glaciers stay silent, never protest - yet their silence signals danger, not peace. Their absence will be felt in rivers that dry, crops that fail, and cities that burn in thirst. </p>



<p>By observing World Water Day, we give glaciers a voice. We turn their melting into a message.</p>



<p><a href="https://www.earth.com/news/water-appears-to-have-a-secret-liquid-phase/" target="_blank" rel="noreferrer noopener">Water</a> connects us all. It flows through our histories, our cultures, and our futures. If we choose not to act, future generations will look back and wonder why.</p>



<p>This World Water Day, let’s be remembered not for our silence, but for our action.</p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

Scientists discover we age in bursts

<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>
