<p>Not everything in the universe is what it seems. Some things, like tiny red objects captured by NASA’s James Webb Space Telescope (JWST), might look like stars or galaxies. But new research suggests they could be something else entirely - something we’ve never seen before.</p>



<p>The objects, called “little red dots,” were first spotted when Webb returned its initial pictures in 2022. The dots appeared where <a href="https://www.earth.com/news/young-galaxy-shows-us-what-the-early-milky-way-looked-like/">young galaxies</a> would be alone, 500 to 700 million years after the Big Bang. But they were too bright and too big to be galaxies that early in the universe. Something wasn’t adding up.</p>



<p>For a while, researchers thought they had discovered ancient, mature galaxies that somehow formed way faster than expected - so fast they started calling them “universe breakers.” But after digging deeper, a new idea started to form. Maybe these weren’t <a href="https://www.earth.com/news/thousands-of-galaxies-revealed-in-a-single-webb-image/">galaxies</a> at all.</p>



<h2 class="wp-block-heading" id="h-a-star-that-s-hiding-a-black-hole">A star that's hiding a black hole</h2>



<p>In a recent study, scientists proposed a bold theory: the red dots might be something called a <a href="https://www.earth.com/news/free-floating-black-hole-appears-to-be-feeding-on-a-star/">black hole</a> star. Picture a huge sphere of gas that looks like a cold, low-energy star - but inside, it’s hiding a growing supermassive black hole.</p>



<p>Instead of getting its energy from fusion like a normal star, this object feeds off matter falling into the black hole at its core. That process generates energy and gives off light, creating the bright signal scientists saw.</p>



<p>“Basically, we looked at enough red dots until we saw one that had so much atmosphere that it couldn't be explained as typical stars we’d expect from a galaxy,” said Joel Leja, an associate professor of astrophysics at <a href="https://www.psu.edu/" target="_blank" rel="noreferrer noopener">Penn State</a>. </p>



<p>“It’s an elegant answer really, because we thought it was a tiny galaxy full of many separate cold stars, but it’s actually, effectively, one gigantic, very cold star.”</p>



<h2 class="wp-block-heading" id="h-cold-stars-that-shine-strangely">Cold stars that shine strangely</h2>



<p><a href="https://www.earth.com/video/earth-humans-and-all-living-creatures-are-made-from-stars/">Stars</a> that are cold emit very little visible light. They glow mainly in the red or near-infrared part of the spectrum - a type of light our eyes can’t see. These stars are usually small and faint, which makes them hard to find.</p>



<p>But these red dots stood out. The light they gave off wasn’t from a hot, bright region like we usually see near black holes. Instead, it came from very cold gas, similar to what’s found around low-mass stars.</p>



<p>Webb was built to pick up exactly this kind of ancient, stretched-out infrared light. Its infrared sensors can see light that traveled across the universe for over 13 billion years. That makes it perfect for spotting objects from the very early days of the cosmos.</p>



<h2 class="wp-block-heading" id="h-the-most-extreme-red-dot">The most extreme red dot</h2>



<p>Between January and December 2024, the team gathered spectra - a kind of light fingerprint - from 4,500 galaxies. Spectra can tell scientists how bright something is across different wavelengths, which helps them figure out what it’s made of and how massive it is.</p>



<p>One of these objects stood out. Nicknamed “The Cliff,” it turned out to be the most extreme of all the red dots. It was so far away that its light took about 11.9 billion years to reach Earth.</p>



<p>“The extreme properties of The Cliff forced us to go back to the drawing board, and come up with entirely new models,” said Anna de Graaff, a researcher for the <a href="https://www.mpia.de/en" target="_blank" rel="noreferrer noopener">Max Planck Institute for Astronomy</a>.</p>



<p>Spectral analysis showed that The Cliff wasn’t made up of countless tiny stars. It was a single, massive object - a black hole pulling in gas so fast that it wrapped itself in a glowing shell of <a href="https://www.earth.com/news/massive-star-forming-hydrogen-cloud-discovered-surprisingly-close-to-earth-eos/">hydrogen</a>.</p>



<h2 class="wp-block-heading" id="h-are-black-hole-stars-a-missing-link">Are black hole stars a missing link?</h2>



<p>Black holes are found at the center of most galaxies. Some of them are enormous - millions or even billions of times more massive than our sun. But no one knows exactly how they got that big, or how they formed in the first place.</p>



<p>“No one's ever really known why or where these gigantic black holes at the center of galaxies come from,” said Leja. “These black hole stars might be the first phase of formation for the black holes that we see in galaxies today - <a href="https://www.earth.com/news/supermassive-black-holes-are-much-more-common-in-the-universe-than-believed/">supermassive black holes</a> in their little infancy stage.”</p>



<p>That idea could help solve a major puzzle in astronomy. If these red dots are actually black hole stars, then maybe they’re the missing link - the early-stage objects that grow into the supermassive black holes we see in today’s galaxies.</p>



<h2 class="wp-block-heading" id="h-following-clues-from-the-universe">Following clues from the universe </h2>



<p>The team plans to keep studying these black hole star candidates, especially by looking at how dense the gas is and how strong the light output is. That might help confirm whether they’re really seeing a new type of object.</p>



<p>“This is the best idea we have and really the first one that fits nearly all of the data, so now we need to flesh it out more,” said Leja. </p>



<p>“It's okay to be wrong. The universe is much weirder than we can imagine and all we can do is follow its clues. There are still big surprises out there for us.”</p>

Mystery objects in the early universe may be black hole stars

Not everything in the universe is what it seems. Some things, like tiny red objects captured by NASA’s James Webb Space Telescope (JWST), might look like stars or galaxies. But new research suggests they could be something else entirely - something we’ve never seen before. The objects, called “little red dots,” were first spotted when Webb returned its initial pictures in 2022. The dots appeared where young galaxies would be alone, 500 to 700 million years after the Big Bang. But they were too bright and too...

<p>What if everything we thought we knew about a condition was turned on its head? Imagine Alzheimer's, the notorious affliction of the mind, not being a brain ailment after all, but an autoimmune disorder.</p>



<p>Dr. Donald Weaver, with his team at the <a href="https://www.uhn.ca/Krembil" target="_blank" rel="noreferrer noopener">Krembil Brain Institute</a>, Toronto, has a radical new theory that presents this exact proposition.</p>



<h2 class="wp-block-heading" id="h-doubts-about-alzheimer-s-and-the-brain">Doubts about Alzheimer's and the brain</h2>



<p>The ongoing pursuit of an Alzheimer's cure is a journey fraught with controversies and conflicts. A recent revelation in Science magazine stated that the <a href="https://www.nature.com/articles/nature04533" target="_blank" rel="noreferrer noopener">2006 research paper</a> identifying the beta-amyloid brain protein as the Alzheimer's cause might have been built on erroneous data.</p>



<p>Around the same time, the U.S. Food and Drug Administration (<a href="https://www.fda.gov/" target="_blank" rel="noreferrer noopener">FDA</a>) approved a drug, aducanumab, meant to target beta-amyloid -- an approval mired in controversy due to incomplete and conflicting data.</p>



<p>This approval resulted in an unsettling divide among physicians, with some supporting its chance, and others convinced it should never have seen the light of day.</p>



<h2 class="wp-block-heading" id="h-dilemma-of-beta-amyloid">Dilemma of beta-amyloid</h2>



<p>The pervasive concentration, over the years, on beta-amyloid as the main culprit, appears to have led us through a <a href="https://www.earth.com/news/dopamine-may-help-restore-memory-in-alzheimers-patients/" target="_blank" rel="noreferrer noopener">proverbial rabbit hole</a>. </p>



<p>Regrettably, this unwavering focus has not borne fruit in the form of a working drug or therapy.</p>



<p>Dr. Weaver's lab now redirects the spotlight onto the immune system within the brain, presenting Alzheimer's as not just a <a href="https://www.earth.com/news/dementia-was-extremely-rare-in-ancient-times-so-why-is-it-now-so-prevalent/" target="_blank" rel="noreferrer noopener">brain disease</a>, but an autoimmune disorder.</p>



<h2 class="wp-block-heading" id="h-immune-system-gone-rogue">Immune system gone rogue</h2>



<p>Like any part of our bodies, our brain has an immune system that kicks into action when required - mending wounds, fighting bacterial invasions, and helping repair after trauma.</p>



<p>Dr. Weaver's team suggests the infamous beta-amyloid might not be an abnormal protein after all, but a normal compound that forms part of the <a href="https://www.earth.com/news/ai-tool-better-predicting-alzheimers-disease-than-current-tests/" target="_blank" rel="noreferrer noopener">brain's immune system</a>.</p>



<p>Trouble brews when beta-amyloid's inability to differentiate between invading bacteria and brain cells causes it to attack and destroy the very cells it should protect, eventually leading to a loss of brain function and, finally, dementia.</p>



<h2 class="wp-block-heading" id="h-curing-alzheimer-s-outside-the-brain">Curing Alzheimer's outside the brain</h2>



<p>Promisingly, this new perspective on Alzheimer's opens up the exploration of alternative immune-regulating pathways, paving the way for <a href="https://www.earth.com/news/blood-tests-offer-new-hope-in-detecting-alzheimers/" target="_blank" rel="noreferrer noopener">potential new treatments</a>.</p>



<p>Conventional drugs used for autoimmune diseases may not work, but don't lose heart. The answer might lie in tackling other immune-modulating pathways in the brain, providing hope for new and effective treatments.</p>



<p>This is not the only new theory cropping up around Alzheimer's. Some scientists speculate that Alzheimer's is a disease of mitochondria, while others argue that it might stem from an infection, particularly by mouth bacteria. </p>



<p>Other scientists are looking into abnormal handling of metals like zinc, copper, or iron in the brain.</p>



<h2 class="wp-block-heading" id="h-alzheimer-s-disease-is-a-global-issue">Alzheimer's disease is a global issue</h2>



<p>Alzheimer's, affecting over 50 million people across the globe, with a new diagnosis every three seconds, is a growing <a href="https://www.earth.com/news/alzheimers-disease-earliest-biomarker-protein-psd-95-identified/" target="_blank" rel="noreferrer noopener">public health crisis</a>. </p>



<p>People with Alzheimer's sometimes fail to recognize their own children or lifelong partners, underscoring the devastating impact of this formidable disease.</p>



<p>As researchers investigate these diverse avenues, collaboration across disciplines becomes imperative. </p>



<p>The challenges of Alzheimer's demand a consolidated effort from neurologists, immunologists, and pharmacologists, fostering interdisciplinary dialogue to unravel this complex condition.</p>



<p>The urgency to comprehend the <a href="https://www.earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">multifaceted nature of Alzheimer's</a> cannot be overstated, for every insight brings us one step closer to not only understanding but potentially eradicating a disease that diminishes quality of life for millions.</p>



<h2 class="wp-block-heading" id="h-future-of-alzheimer-s-and-brain-research">Future of Alzheimer's and brain research</h2>



<p>In a refreshing new avenue of research, Dr. Douglas Kelley from the <a href="https://www.rochester.edu/" target="_blank" rel="noreferrer noopener">University of Rochester</a> and his team have found an intriguing link between a type of drug used to induce labor in pregnant women and Alzheimer's.</p>



<p>They found that these drugs could potentially speed up the brain's waste clearing system, which is dysfunctional in those suffering from Alzheimer's.</p>



<p>By applying these drugs, which cause muscle contractions, they found some restorative effects. "One can see how this approach, perhaps combined with other interventions, could be the basis for future therapies for these diseases," Dr. Kelley said.</p>



<p>Whether the answer lies in shifting our view of Alzheimer's from a brain disorder to an autoimmune disease or in using existing drugs in new ways, the journey to find a solution continues with inexhaustible determination. Through persistent research, the world still hopes for light at the end of the Alzheimer's tunnel.</p>

Alzheimer's may not be a brain disorder, important data was fabricated

What if everything we thought we knew about a condition...

<p>The realities of fatherhood are shifting as more men are choosing to <a href="https://www.earth.com/news/fatherhood-takes-a-toll-on-heart-health/" target="_blank" rel="noreferrer noopener">have children later in life</a>. This surprising new trend, often associated with the affluent and famous, actually extends to a diversity of individuals – professionals, laborers, and those of varied racial and educational backgrounds.</p>



<p>Albert Ha, a distinguished researcher from <a href="https://www.stanford.edu" target="_blank" rel="noreferrer noopener">Stanford University</a>, has led an enlightening study on this emerging pattern. </p>



<p>By examining over 46 million U.S. births from 2011 to 2022, he and his team made some startling discoveries that challenge societal norms surrounding fatherhood.</p>



<h2 class="wp-block-heading" id="h-changing-face-of-late-fatherhood">Changing face of late fatherhood</h2>



<p>According to Ha's research, the number of babies born to fathers aged 50 and above is slowly inching upward. But contrary to widely held beliefs, older fathers aren't predominantly wealthy tycoons or A-list celebrities. </p>



<p>This trend spans diverse racial backgrounds and education levels, debunking stereotypes with solid facts and statistics. </p>



<p>So, who are these older dads? They mostly include university professors, skilled tradesmen like electricians and plumbers, retired military personnel, and professionals in various fields like engineering and healthcare.</p>



<p>These older fathers are not just a newset of statistics. There's a nuanced story here - their decision to have children later in life can potentially impact their offspring's health and future. </p>



<p>Ha's research showed that babies born to fathers aged 50 and above have slightly higher risks of premature birth and low birth weight. While these are not alarmingly high risks, they do warrant attention and further investigation.</p>



<h2 class="wp-block-heading" id="h-twist-in-the-tale">Twist in the tale</h2>



<p>In an interesting turn of events, Ha's study revealed that men over 70 were less likely to have male children. While this bucks expectations, it also adds a fascinating layer to our understanding of how paternal age can influence the sex of a child.</p>



<p>Assisted reproductive technology (ART) is also being increasingly employed by older would-be fathers. As these men age, they turn to science and technology to help them become dads. This reflects the significant role that fertility treatments now play in family planning.</p>



<p>The study also presented the increasing trend of older men fathering children with first-time mothers over the age of 25. This finding indicates a shift in family trends as more couples choose to delay starting families.</p>



<p>“These ongoing societal shifts underscore the need for <a href="https://www.earth.com/news/2024-resolutions-better-parenting-and-family-health-are-top-priorities/" target="_blank" rel="noreferrer noopener">public education</a> and further research into the benefits and drawbacks of delayed fatherhood,” noted the study authors.</p>



<h2 class="wp-block-heading" id="h-fathers-aged-50-and-above">Fathers aged 50 and above</h2>



<p>Ha's team relied on data from the National Vital Statistics System, which aggregates information from all U.S. birth certificates. They scrutinized several factors, including paternal age, race, education, and maternal characteristics. To account for any data gaps, they employed a statistical method known as inverse probability weighting.</p>



<p>The results showed that the percentage of births to fathers aged 50 and above increased from 1.1% in 2011 to 1.3% in 2022. This rise also saw a surge in racial diversity among these fathers and a range in education levels. Additionally, the study found that the use of ART was much higher within this demographic.</p>



<p>The study, however, does have its limitations – it rests heavily on birth certificate data, which may not capture every relevant detail. Additionally, while the researchers accounted for many factors, they couldn't control for everything. Other unmeasured influences might still impact the results.</p>



<h2 class="wp-block-heading" id="h-digging-deeper-into-late-fatherhood">Digging deeper into late fatherhood</h2>



<p>The research doesn't just challenge stereotypes about older fatherhood. It makes a compelling case for more public education and conversation around delayed parenthood. </p>



<p>Along with potential liabilities, older fatherhood might also offer benefits like financial stability and emotional maturity. Ha's work emphasizes the importance of considering paternal age in <a href="https://www.earth.com/news/parents-who-use-humor-have-better-relationships-with-their-children/" target="_blank" rel="noreferrer noopener">family planning</a> discussions and medical care.</p>



<p>The study was carried out by researchers at Stanford University. For the sake of transparency, one researcher, Dr. Michael L. Eisenberg, reported serving as a consultant for several companies in the fertility industry. This allows readers to weigh any potential conflicts of interest.</p>



<p>So, as we witness these societal shifts that are changing the face of fatherhood, we must keep an open mind. The time has come to unpack and understand the implications of delayed fatherhood, both for the parents and their children.</p>



<p>The study is published in the journal <em><a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2821811" target="_blank" rel="noreferrer noopener">JAMA Network Open</a></em>.</p>

Late fatherhood is becoming increasingly popular in the U.S.

The realities of fatherhood are shifting as more men are...

<p>With a click of a button, we are transported from one side of the planet to the other, thanks to the world of online videos. However, have you ever wondered about the paradox of feeling more bored after making a "digital switch," that is, <a href="https://www.earth.com/news/doomscrolling-threatens-our-mental-well-being/" target="_blank" rel="noreferrer noopener">moving from one video to another</a> as a way to relieve your boredom?</p>



<p>Recent research has extensively investigated this phenomenon. And the results? Well, they might make you re-think your video watching habits.</p>



<p>Released by the <a href="https://www.apa.org" target="_blank" rel="noreferrer noopener">American Psychological Association</a>, the research picked the brains of more than 1,200 participants - both from the populace of the United States as well as college scholars at the <a href="https://www.utoronto.ca" target="_blank" rel="noreferrer noopener">University of Toronto</a>.</p>



<h2 class="wp-block-heading" id="h-digital-switching-and-boredom">Digital switching and boredom</h2>



<p>The mastermind behind this enlightening study is Dr. Katy Tam. She is a postdoctoral researcher at the University of Toronto and has earned her stripes in exploring the nuances of the human psyche. </p>



<p>"If people want a more enjoyable experience when watching videos, they can try to stay focused on the content and minimize digital switching. Just like paying for a more immersive experience in a movie theater, more enjoyment comes from immersing oneself in online videos rather than swiping through them," noted Dr. Tam.</p>



<h2 class="wp-block-heading" id="h-watching-online-videos-to-cure-boredom">Watching online videos to cure boredom</h2>



<p>Spread across seven experiments, the participants were asked to engage with various video-viewing activities. The baseline experiments had the participants <a href="https://www.earth.com/news/gen-ai-and-social-media-divert-peoples-attention-from-climate-crisis/" target="_blank" rel="noreferrer noopener">switch from one online video</a> to another when they felt bored.</p>



<p>By contrast, other experiments had the participants watch a single 10-minute YouTube video without the option to fast forward. Alternately, they could switch through several five-minute videos within the same 10-minute timeframe. You'd think switching would be less boring, right? Quite the opposite, according to Dr. Tam's findings.</p>



<p>The participants reported that they felt less bored when they watched a single video. They found the viewing experience to be more satisfying, engaging, and meaningful than when they were jumping from video to video.</p>



<h2 class="wp-block-heading" id="h-implications-of-digital-switching">Implications of digital switching</h2>



<p>The findings from Dr. Tam's research raise important questions about the consequences of our increasingly fragmented online viewing habits. </p>



<p>In our fast-paced, digital environment, it can be easy to underestimate the impact of constant switching on our capacity for engagement and satisfaction. </p>



<p>The sheer availability of content often leads users to chase novelty rather than depth, potentially diminishing the overall enjoyment and meaning derived from video consumption. </p>



<p>As we navigate this landscape filled with competing stimuli, it becomes crucial to consider how our choices shape not only our immediate experiences but also our longer-term relationship with digital media.</p>



<h2 class="wp-block-heading" id="h-suggestions-for-mindful-viewing">Suggestions for mindful viewing</h2>



<p>For a more fulfilling digital experience, viewers may benefit from adopting mindful video-watching practices. </p>



<p>These can include setting aside dedicated time for viewing without distractions, prioritizing longer formats that encourage deeper engagement, and consciously selecting content that resonates with one’s interests and values.</p>



<p>By embracing this approach, individuals could cultivate a more appreciative relationship with audiovisual media - transforming passive consumption into a more enriching and enjoyable experience.</p>



<p>Ultimately, by redefining our engagement with online videos, we not only enhance our entertainment but also contribute to our overall well-being in the digital age.</p>



<h2 class="wp-block-heading" id="h-online-videos-don-t-always-increase-boredom">Online videos don't always increase boredom </h2>



<p>The results of this study might make us re-evaluate our boredom coping mechanisms. Perhaps sticking to one video and absorbing its content is more beneficial than being digital butterflies, fluttering from one video to the next.</p>



<p>Note that this study hasn't examined whether short attention spans contribute to any increase in boredom or switching online videos. Since the participants in several experiments were primarily Canadian college students, there might be differences based on age or experience with digital media.</p>



<p>While we may love to whip out our smartphones while standing in a queue, prior research has shown that smartphone use can increase boredom. Adding to that, digital switching might be<a href="https://www.earth.com/news/boredom-can-make-children-more-creative-and-teach-new-skills/" target="_blank" rel="noreferrer noopener"> another source</a> of boredom, perhaps leading to negative mental health consequences.</p>



<p>So the next time you find yourself mindlessly thumbing through an endless stream of videos, remember Dr. Tam's words. Press pause on your digital switching, and who knows, you might just find yourself less bored. After all, aren't we all in pursuit of enjoying online content more and being bored less?</p>



<p>The study is published in the <em><a href="https://psycnet.apa.org/doiLanding?doi=10.1037%2Fxge0001639" target="_blank" rel="noreferrer noopener">Journal of Experimental Psychology</a>.</em></p>

Scrolling online videos is not a good cure for boredom

With a click of a button, we are transported from...

<p>Scientists have discovered promising clues for treating diabetes and hormone disorders in an unexpected source: the venom of one of the world’s most toxic creatures, the marine <a href="https://www.earth.com/news/cone-snail-venom-could-be-used-to-produce-painkillers/" target="_blank" rel="noreferrer noopener">cone snail</a>. </p>



<p>A research team led by scientists from the <a href="https://www.utah.edu/" target="_blank" rel="noreferrer noopener">University of Utah</a> has identified a component in the venom of the geography cone, a species of cone snail, that mimics a human hormone known as somatostatin. This hormone regulates <a href="https://www.earth.com/news/evening-workouts-are-best-for-blood-sugar-control/" target="_blank" rel="noreferrer noopener">blood sugar</a> levels and various hormones in the body. </p>



<h2 class="wp-block-heading" id="h-snail-venom-as-a-blueprint-nbsp">Snail venom as a blueprint<strong>&nbsp;</strong></h2>



<p>The snail’s venom, which has evolved to assist in hunting prey, could potentially offer a blueprint for developing more effective drugs to treat diabetes and hormone-related conditions, which can be severe and life-threatening.</p>



<p>The venom component identified by the researchers, named consomatin, could be key to improving medications for managing diabetes and hormone disorders.&nbsp;</p>



<p>In humans, somatostatin acts as a regulator, preventing blood sugar and hormone levels from rising to dangerous levels. The cone snail’s consomatin behaves similarly but is more stable and precise than the human hormone, making it a promising model for drug development.</p>



<h2 class="wp-block-heading" id="h-precise-targeting-of-snail-venom">Precise targeting of snail venom</h2>



<p>The researchers conducted experiments to see how consomatin interacts with somatostatin’s targets in human cells. They discovered that while somatostatin interacts with multiple proteins, consomatin specifically targets only one.&nbsp;</p>



<p>This precise targeting means that the toxin from the cone snail can influence hormone and blood sugar levels without affecting many other molecules in the body.</p>



<p>Notably, consomatin’s precision surpasses even the most advanced synthetic drugs currently used to regulate hormone levels, such as those used to control growth hormone. These drugs are vital for treating individuals whose bodies produce excessive growth hormone.&nbsp;</p>



<p>While consomatin’s effect on blood sugar might make it unsuitable for direct therapeutic use, its structure could inspire the creation of drugs for <a href="https://www.earth.com/news/contaminants-water-supply-endocrine/" target="_blank" rel="noreferrer noopener">endocrine disorders</a> with fewer side effects.</p>



<h2 class="wp-block-heading" id="h-valuable-insights-for-drug-development-nbsp">Valuable insights for drug development<strong>&nbsp;</strong></h2>



<p>Moreover, consomatin has another advantage: it remains active in the body much longer than human somatostatin due to the presence of an unusual amino acid that makes it resistant to breakdown. This durability is a valuable trait for pharmaceutical researchers aiming to develop drugs that provide prolonged benefits.</p>



<p>The idea of finding new drugs by studying deadly venoms might seem counterintuitive. However, the precision of these venoms in targeting specific molecules can be highly useful in treating diseases, noted Helena Safavi, an associate professor of biochemistry at the University of Utah’s Spencer Fox Eccles School of Medicine (SFESOM) and the senior author of the study.</p>



<p>“<a href="https://www.earth.com/news/dangerous-desert-creatures/" target="_blank" rel="noreferrer noopener">Venomous animals</a> have, through evolution, fine-tuned venom components to hit a particular target in the prey and disrupt it,” said Professor Safavi. This specificity, when isolated and studied, often reveals pathways that are highly relevant in disease treatment. For medicinal chemists, this can serve as a significant shortcut in drug development.</p>



<h2 class="wp-block-heading" id="h-snail-venom-and-blood-sugar-regulation-nbsp">Snail venom and blood sugar regulation<strong>&nbsp;</strong></h2>



<p>Consomatin, while related to somatostatin, has been modified by millions of years of evolution to serve as a potent weapon for the cone snail. The snail uses this toxin to disrupt its prey’s blood sugar regulation, rendering the prey incapacitated.</p>



<p>The research team had previously discovered that the cone snail’s venom includes another toxin similar to insulin, which rapidly lowers blood sugar levels, making the prey unresponsive. Consomatin then keeps the blood sugar levels low, preventing recovery.</p>



<p>“We think the cone snail developed this highly selective toxin to work together with the insulin-like toxin to bring down blood glucose to a really low level,” said Ho Yan Yeung, a postdoctoral researcher at SFESOM and the study’s first author.</p>



<h2 class="wp-block-heading" id="h-broader-implications-of-the-study-nbsp">Broader implications of the study<strong>&nbsp;</strong></h2>



<p>The presence of multiple toxins in the snail’s venom that target blood sugar regulation suggests that there may be even more compounds with similar properties waiting to be discovered. These could potentially be used to design better medications for <a href="https://www.earth.com/news/exercise-can-counteract-the-genetic-risk-for-diabetes/" target="_blank" rel="noreferrer noopener">diabetes</a>.</p>



<p>It might be surprising that a snail can outperform human chemists in designing effective drugs, but as Professor Safavi points out, the cone snails have had millions of years to perfect their biochemistry.&nbsp;</p>



<p>“We’ve been trying to do medicinal chemistry and drug development for a few hundred years, sometimes badly,” she said. “Cone snails have had a lot of time to do it really well.”</p>



<p>Or, as Yeung aptly concludes, “cone snails are just really good chemists.”</p>

Deadly snail venom could be key to improving diabetes medicine

Scientists have discovered promising clues for treating diabetes and hormone...

<p>In the bustling world of <a href="https://www.earth.com/news/global-biodiversity-crisis-is-actually-worse-than-we-thought/" target="_blank" rel="noreferrer noopener">biodiversity</a>, ants have long been the missing piece in a puzzle we've been assembling for nearly 150 years. </p>



<p>While it's a well-established fact that species distribution around the globe is influenced by a blend of evolutionary mechanisms and environmental factors, our understanding has been based exclusively on vertebrates and plants - until now.</p>



<p>These "little things that run the world" have finally taken center stage, revealing new insights into the biogeographic realms that shape life on Earth.</p>



<h2 class="wp-block-heading" id="h-biogeographic-realms-in-biodiversity">Biogeographic realms in biodiversity</h2>



<p>The <a href="https://www.earth.com/news/how-do-temperature-extremes-change-the-distribution-of-species/" target="_blank" rel="noreferrer noopener">distribution of species</a> around the globe is not a random process but an outcome of evolutionary mechanisms and environmental limitations, both past and present. </p>



<p>Since the mid-19th century, biologists have identified key regions, known as biogeographic realms, that depict these large ensembles of species around the world. </p>



<p>These realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used across various biological fields.</p>



<h2 class="wp-block-heading" id="h-filling-the-insect-knowledge-gap">Filling the insect knowledge gap</h2>



<p>However, for nearly 150 years, the characterization of these biogeographic units has been based solely on vertebrates (e.g., birds, mammals) and plant groups. </p>



<p>These groups represent only a small fraction of <a href="https://www.earth.com/news/sounding-the-alarm-half-of-earths-species-are-experiencing-rapid-population-decline/" target="_blank" rel="noreferrer noopener">Earth's species</a>, leaving hyperdiverse organisms like insects largely out of the picture. </p>



<p>This gap in knowledge has posed a significant challenge for conservation planning and understanding biodiversity distribution.</p>



<h2 class="wp-block-heading" id="h-mapping-the-biodiversity-of-ants">Mapping the biodiversity of ants</h2>



<p>Recently, ecologists from <a href="https://www.hku.hk/" target="_blank" rel="noreferrer noopener">The University of Hong Kong</a> (HKU) and their collaborators in Japan took a major step to fill this gap by mapping the global biogeographic regions for ants. </p>



<p>This work, published in <em>Nature Communications</em>, provides the first comprehensive effort to include insects in such studies and offers new approaches to understanding their distribution. The study marks a significant milestone in global conservation efforts.</p>



<h2 class="wp-block-heading" id="h-ants-the-little-giants-of-biodiversity">Ants: The little giants of biodiversity</h2>



<p>Insects make up over 55% of all described species, yet the knowledge gap regarding their distribution has hindered scientists' ability to map their biogeographic regions. </p>



<p>"A first step to protect species, and thus biodiversity, is to understand where those are located," noted Professor Benoit Guénard, senior author of the study and head of the Insect Biodiversity and Biogeography Laboratory at HKU’s School of Biological Sciences (SBS).</p>



<p>To tackle this challenge, Professor Guénard has led an international team for more than a decade to assemble distribution data for nearly 16,000 <a href="https://www.earth.com/news/newly-discovered-leptanilla-ant-named-after-harry-potter-villain/" target="_blank" rel="noreferrer noopener">ant species</a>.</p>



<p>Ants are among the most widespread and ecologically dominant insects, with a combined mass that exceeds that of all wild birds and mammals, as shown in a previous study by Professor Guénard's team.</p>



<h2 class="wp-block-heading" id="h-first-global-biogeographic-map-of-ants">First global biogeographic map of ants</h2>



<p>For an insect group, ants are relatively well-documented. The team's extensive work, compiling data from over 300 years of ant research, enabled them to use advanced techniques, including bioinformatics and machine learning, to predict and analyze their distribution.</p>



<p>This effort culminated in the creation of the first-ever biogeographic <a href="https://www.earth.com/news/treasure-map-will-help-experts-find-new-ant-species/" target="_blank" rel="noreferrer noopener">map of ants</a>. The map reveals the division of ants' global territory into nine large biogeographic realms.</p>



<p>"Interestingly, when I was comparing this map with those for vertebrates and plants, I saw so many similarities," said study first author Runxi Wang, a PhD candidate in HKU’s School of Biological Sciences. "Ants and plants share several regions that are not found in vertebrates."</p>



<h2 class="wp-block-heading" id="h-ecological-relationship-of-ants-and-plants">Ecological relationship of ants and plants </h2>



<p>Further analysis confirmed these observations - the biogeographic regions are strikingly similar across different taxa, but ants and plants share a closer resemblance than any vertebrate groups.</p>



<p>"It's not very surprising because we know that ants and plants have very close ecological and evolutionary relationships," explained Professor Guénard.</p>



<p>"For instance, ants help tens of thousands of plants to disperse their seeds and protect many more from herbivores. They have co-evolved for millions of years, but this is one of the first pieces of evidence showing such significant biogeographic consequences."</p>



<h2 class="wp-block-heading" id="h-ants-and-future-biodiversity-research">Ants and future biodiversity research </h2>



<p>The results of the study suggest that many similarities between animals and plants might not be captured by looking only at vertebrates.</p>



<p>"Ants alone cannot represent the hyperdiversity of all insects, but their similarities to plants are probably not an exception," said Wang. "We certainly need greater efforts to include more insect groups in the future to depict the global picture of biodiversity."</p>



<p>The full study was published in the journal <em><a href="https://www.nature.com/articles/s41467-024-49918-2" target="_blank" rel="noreferrer noopener">Nature Communications</a></em>.</p>

Ants fill a 150-year gap in biodiversity research

In the bustling world of biodiversity, ants have long been...

<p>Despite significant progress in clean energy, global <a href="https://www.earth.com/news/global-carbon-dioxide-emissions-hit-a-record-high-in-2023/" target="_blank" rel="noreferrer noopener">CO2 emissions</a> continue to rise. This highlights the need for a more integrated approach that combines technological advancements with strong institutional capacities to formulate effective policies to reach global climate goals. </p>



<p>Researchers from the <a href="https://iiasa.ac.at/" target="_blank" rel="noreferrer noopener">International Institute for Applied Systems Analysis</a> (IIASA) have contributed to a new international study that emphasizes this crucial integration as essential for meeting the ambitious goals of the Paris Agreement.</p>



<h2 class="wp-block-heading" id="h-co2-emissions-on-the-rise">CO2 emissions on the rise</h2>



<p>The Paris Agreement aims to limit global warming to 1.5°C, a target that requires rapid reductions in CO2 emissions and a greater focus on reducing non-CO2 greenhouse gases.&nbsp;</p>



<p>However, despite advancements in clean energy technologies, global CO2 emissions have been on the rise for the past three years, reversing the temporary decline observed during the <a href="https://www.earth.com/news/the-pandemic-shows-us-how-to-tackle-the-climate-crisis/" target="_blank" rel="noreferrer noopener">COVID-19 pandemic</a> in 2020.</p>



<p>Published in <a href="https://dx.doi.org/10.1038/s41558-024-02073-4"><em>Nature Climate Change</em></a>, the study was led by the <a href="https://cgs.umd.edu/" target="_blank" rel="noreferrer noopener">Center for Global Sustainability</a> (CGS) at the University of Maryland, in collaboration with the IIASA-led <a href="https://iiasa.ac.at/projects/engage" target="_blank" rel="noreferrer noopener">ENGAGE project</a> (Exploring National and Global Actions to reduce Greenhouse gas Emissions). This global consortium brings together leading research groups from various disciplines to address the complex challenges of climate change.</p>



<p>“These new insights highlight the critical challenges in meeting the Paris Agreement's long-term goals given recent global climate-damaging emissions trends,” said Bas van Ruijven, a co-author of the study and coordinator of the ENGAGE project.</p>



<h2 class="wp-block-heading" id="h-feasible-pathways-to-climate-goals">Feasible pathways to climate goals</h2>



<p>The researchers aimed to generate knowledge that could inform the design of cost-effective, technologically viable, and socially and politically feasible pathways to achieve the Paris Agreement's objectives.&nbsp;</p>



<p>Using eight advanced multi-regional and process-based global integrated assessment models (IAMs) and analyzing 20 different feasibility scenarios, the researchers found that the institutional dimension - specifically, the capacity of countries to implement effective climate regulation - plays the most significant role in determining feasible peak temperatures.</p>



<p>“Through rigorous analysis of <a href="https://www.earth.com/news/worst-case-climate-scenarios-are-no-longer-plausible/" target="_blank" rel="noreferrer noopener">climate scenarios</a> across eight different models, our research underscores the importance of accounting for the varying capacities of countries as well as regional differences,” explained Christoph Bertram, an associate research professor at CGS and lead author of the study.</p>



<h2 class="wp-block-heading" id="h-new-approach-to-climate-goals">New approach to climate goals</h2>



<p>The study demonstrates that when institutional constraints are considered alongside technological and socio-cultural factors, the most feasible pathways to achieving the Paris climate goals differ significantly from the cost-effective benchmarks that are often used.</p>



<p>“From an international fairness perspective, this also means that today's affluent countries like the US and the EU not only need to reach their net-zero targets, but they need to think about multilateral collaborations to enhance governance and institutional capacity in vulnerable regions,” added Keywan Riahi, co-author of the study and director of the Energy, Climate, and Environment Program at IIASA.</p>



<p>By incorporating region-specific governance indicators, the study showcases the varying capacities of regions to implement climate mitigation policies effectively.&nbsp;</p>



<p>This approach builds on earlier work conducted under the ENGAGE project, which assessed the feasibility of transformation pathways for achieving the Paris Climate Agreement and served as a foundation for developing the new scenarios.</p>



<h2 class="wp-block-heading" id="h-institutional-capacity-across-different-regions-nbsp">Institutional capacity across different regions<strong>&nbsp;</strong></h2>



<p>The tools and methodologies developed as part of the ENGAGE project to explore the multidimensional feasibility of decarbonization pathways have been made available to decision-makers in a Summary for Policymakers.&nbsp;</p>



<p>The new study adds a nuanced framework that can be used in future research to represent institutional capacity across different regions and over time.</p>



<p>“These new scenarios explore the implications of having many countries that potentially lack the institutional capacity to implement ambitious climate policies,” said Elina Brutschin, a co-author of the study and researcher in the IIASA Transformative Institutional and Social Solutions Research Group.&nbsp;</p>



<p>“With additional strategies such as rapid demand-side transformation (especially in affluent countries) combined with fast electrification, it could still be possible to limit peak temperature to below 1.7°C.”</p>



<h2 class="wp-block-heading" id="h-technological-feasibility-of-climate-neutrality">Technological feasibility of climate-neutrality</h2>



<p>Study co-author Gunnar Luderer leads the Energy Systems Group at the <a href="https://www.pik-potsdam.de/en/home" target="_blank" rel="noreferrer noopener">Potsdam Institute for Climate Impact Research</a> (PIK) and is a professor of global energy systems analysis at the <a href="https://www.tu.berlin/en/" target="_blank" rel="noreferrer noopener">Technical University of Berlin</a>. </p>



<p>Luderer noted that thanks to the latest advances in low carbon technology deployment such as solar, wind, or electric vehicles, the technological feasibility of climate-neutrality is no longer the most crucial issue. “It is much more about how fast climate policy ambition can be ramped up by governments.”</p>



<p>The research underscores the critical need to balance technological advancements with institutional capabilities when formulating effective climate policies. It demonstrates that inadequate institutional capacity could hinder the achievement of even a 2°C target, while improved global institutional support could increase the likelihood of meeting the 1.6°C target by up to 45 percent.</p>



<p>As the global community intensifies its efforts toward the 1.5°C goal, it is imperative to identify pathways that enhance the feasibility of climate actions and reduce <a href="https://www.earth.com/news/calculating-cost-climate-change-2/" target="_blank" rel="noreferrer noopener">carbon costs</a>. </p>



<p>The study's findings offer valuable insights for guiding ongoing climate policy discussions and future scenario assessments, thereby supporting informed decision-making on global climate ambitions.</p>

Capable countries must take the lead on climate goals

Despite significant progress in clean energy, global CO2 emissions continue...

<p>When walking your dog during the scorching summer heat, you should think twice about allowing them to drink from public water sources. That is the recent warning issued by veterinarians.</p>



<p>it may be tempting to let your furry friend drink from various water sources encountered along the way, such as puddles, fountains, or even streams.</p>



<p>However, it's important to understand that these shared public water sources can pose significant dangers to your dog’s health.</p>



<p>Contaminated water can harbor harmful bacteria, parasites, or chemicals that may lead to gastrointestinal issues or more severe illnesses.</p>



<p>Lori Teller, a clinical professor at the <a href="https://vetmed.tamu.edu/" target="_blank" rel="noreferrer noopener">Texas A&amp;M</a> School of Veterinary Medicine and Biomedical Sciences, has identified the main risks dogs are exposed to when consuming water outside their homes.</p>



<h2 class="wp-block-heading" id="h-importance-of-keeping-dogs-hydrated">Importance of keeping dogs hydrated</h2>



<p>Keeping your dog well-hydrated is really important for their overall health and happiness. Just as it is with humans, water is essential for most of your dog's body functions, like digestion and temperature control. A well-hydrated pup is likely to have more energy, a healthy appetite, and better resistance to illness.</p>



<p>On average, your dog needs about one ounce of water for every pound they weigh each day. This can change based on how active they are, what they eat, and the weather. </p>



<p>When you are out and about in hot weather, it's very important that you keep a close eye on your furry friend in order to spot signs of dehydration. These include dry gums, lethargy, sunken eyes, and less elastic skin, to help keep your pet healthy.</p>



<h2 class="wp-block-heading" id="h-quality-of-public-water-sources">Quality of public water sources</h2>



<p>Teller recommends <a href="https://www.earth.com/news/dogs-humans-close/" target="_blank" rel="noreferrer noopener">dog owners</a> to take into consideration the quality of the public <a href="https://www.earth.com/news/forever-chemicals-are-an-underestimated-source-of-water-contamination/" target="_blank" rel="noreferrer noopener">water</a> sources before letting their pets drink from them, since a well-meaning gesture by a neighbor or local business owner may in fact contain various contaminants. </p>



<p>“This is of particular concern if the bowl is not cleaned regularly or if the water is left standing for extended periods of time,” said Teller.</p>



<p>“Stagnant water can retain environmental contaminants, such as plant material, parasites, toxins, mold, and more. Dogs that have stepped in fecal matter and then played in the bowl could leave parasites and bacteria in the water.”</p>



<h2 class="wp-block-heading" id="h-health-risks-for-dogs-drinking-public-water">Health risks for dogs drinking public water </h2>



<p>According to her, there are many possible diseases which can be transmitted from public water bowls, including:</p>



<ul class="wp-block-list">
<li>Kennel cough: a respiratory infection leading to a gag-like cough, appetite loss, and breathing difficulties;<br></li>



<li>Canine papilloma: a virus spread through saliva causing warts in and around the mouth;<br></li>



<li>Salmonella: an infection causing vomiting, fever, and bloody diarrhea;<br></li>



<li>Giardia: a parasite that leads to vomiting, diarrhea, and weight loss;<br></li>



<li><a href="https://www.earth.com/news/why-dangerous-e-coli-strains-come-from-cattle/" target="_blank" rel="noreferrer noopener">E. coli</a>: a bacterium causing lack of appetite, diarrhea, and dehydration; and <br></li>



<li>Leptospirosis: a bacterial infection frequently spread through rodent urine, leading to kidney or liver disease.</li>
</ul>



<p>Awareness of these risks is essential for protecting dogs, particularly if owners consider their pets’ water needs before leaving the house.</p>



<p>“Ideally, owners would carry a collapsible, portable bowl and some fresh water with them to give to their dog,” Teller advised. </p>



<p>“Alternatively, they could stop at a restaurant or convenience store and request a cup of water for their dog.”</p>



<h2 class="wp-block-heading" id="h-use-your-best-judgement">Use your best judgement</h2>



<p>Nonetheless, although potential risks will always be present in public water sources, there are certain situations when these risks are worth taking.&nbsp;</p>



<p>“If your dog is hot and thirsty and at risk of <a href="https://www.earth.com/news/birds-dehydration-climate-change/" target="_blank" rel="noreferrer noopener">dehydration</a>, then that may take precedence over avoiding the water in the bowl,” Teller said.</p>



<p>Excessive panting can be a sign of dehydration, especially if it continues after the dog has cooled down. In addition, your dog's nose and gums may become dry and sticky due to dehydration.&nbsp;</p>



<h2 class="wp-block-heading" id="h-multiple-pets-sharing-food-bowl">Multiple pets sharing food bowl</h2>



<p>Besides taking into consideration the safety concerns linked to publicly shared water bowls, Teller recommends owners to also consider the risks associated with multiple pets sharing the same food bowl in the same home.&nbsp;</p>



<p>“Often, dogs may need different portions of food, and in many cases, one dog may need a diet change due to a medical condition; that can be much more challenging to manage if the dogs share a bowl,” Teller said. “Or, one dog may prevent another from eating out of the bowl.”</p>



<p>However, as she makes clear, using the same water bowl in a household of multiple pets does not bring similar problems as food bowl sharing.&nbsp;</p>



<p>“In most cases, dogs living in the same house will be exposed to similar infectious agents, so sharing a water bowl will not have a tremendous impact on that,” she said. “It is still important that water bowls (and food bowls) be washed with soap and hot water on a regular basis.”</p>



<p>Determining whether a public water bowl is safe for your thirsty dog should be evaluated on a case-by-case basis. Teller emphasizes that if the water resembles pond water, it's best to prevent your dog from drinking it.&nbsp;</p>



<p>When uncertain, it's always wiser to err on the side of caution, as risking your beloved pet's health isn't worth the gamble.</p>

Warning: Letting dogs drink from public water sources is dangerous

When walking your dog during the scorching summer heat, you...

<p>The heavens are getting ready to roll out a stunning red carpet for a rare "supermoon blue moon" that's about to light up our skies. </p>



<p>This isn’t just any full moon; it's set to outshine and outsize all the other moons we've seen this year, grabbing the attention of stargazers and casual viewers alike.</p>



<p>Make sure to look up on August 19, when the <a href="https://www.earth.com/news/august-nights-perseid-meteor-shower-peaks-this-weekend/" target="_blank" rel="noreferrer noopener">August full moon</a> -- lovingly called the 'Sturgeon Moon' -- will sprinkle its brilliance across the twilight, lighting up the night with its enchanting glow. </p>



<p>This particular moon also goes by the "moon names" of the red, corn, green corn, barley, herb, grain, or dog moon; Raksha Bandhan or Rakhi Purnima; and Tu B'Av.</p>



<p>This supermoon will shine about 30 percent brighter than your average moonlit night, casting long shadows and creating a magical vibe for anyone lucky enough to catch it.</p>



<p>Worried about missing this incredible sight? No need! Over the next few months, the sky will host several of these amazing supermoons, each with its own unique charm.</p>



<h2 class="wp-block-heading" id="h-prime-time-to-view-supermoon">Prime time to view supermoon</h2>



<p><a href="https://www.earth.com/news/super-sturgeon-moon-is-coming-next-week-followed-by-a-rare-blue-moon/" target="_blank" rel="noreferrer noopener">Our Sturgeon moon</a> will reach its zenith at 2:26pm ET on August 19. Those located in the United States may not get a glimpse of it at this time. This is because our lone satellite will be on the other side of our home planet, Earth.</p>



<p>You can still feast your eyes on this celestial marvel at moonrise, which is slated to happen around 8:07 p.m. ET. And you can trust this timing - it's straight from the Farmer's Almanac, known for its reliability.</p>



<p>For spectators on the East Coast, the supermoon will arise in the east-southeastern skies. It will ascend about one-third of the way across the sky before taking a bow at approximately 7:00 a.m. in the west-southwest.</p>



<h2 class="wp-block-heading" id="h-supermoon-when-and-how">Supermoon: When and how?</h2>



<p>If you find yourself pondering over why supermoons look so incredibly large and brilliant, allow us to let you in on the secret. </p>



<p>A supermoon comes into its own, appearing at its maximum size and brightness when it's closest to the horizon. This happens just after moonrise or before moonset. </p>



<p>With the moon playing off against terrestrial objects like trees and buildings, an optical illusion is created that pumps up the moon's size.</p>



<p>This spectacle takes place when the full moon is at 'perigee,' which is the point in its orbit when it's its closest to Earth. </p>



<p>Supermoons scatter about 30 percent more light on our planet than the moon at its dimmest. This is because more of the sun's rays bouncing off the moon's surface reach us on Earth.</p>



<h2 class="wp-block-heading" id="h-more-supermoons-coming-up">More supermoons coming up</h2>



<p>In case you can't make it for this event, there's no reason to be upset. More stargazing opportunities are waiting in the wings. </p>



<p>After the <a href="https://www.earth.com/news/sturgeon-moon-final-supermoon-of-2022-peaks-tonight/" target="_blank" rel="noreferrer noopener">Sturgeon moon</a>, the next supermoons of 2024 are scheduled for September 18, October 17, and November 15.</p>



<p>It's typical to be graced with supermoons three to four times per year, and they always appear in consecutive months.</p>



<h2 class="wp-block-heading" id="h-this-supermoon-is-also-a-blue-moon">This supermoon is also a "blue moon"</h2>



<p>Even though it won't actually look blue, the third full moon in a season with four full moons is called a blue moon. </p>



<p>The first time "<a href="https://www.earth.com/news/august-will-host-two-supermoons-including-a-rare-blue-moon/" target="_blank" rel="noreferrer noopener">blue moon</a>" showed up in English was back in 1528. There's some speculation about where the term comes from -- some say it comes from an old English phrase meaning "betrayer moon," since it messed up the dates for Lent and Easter. </p>



<p>Others think it might refer to those rare times when dust in the atmosphere makes the moon look blue. Since the 1940s, "blue moon" has also been used to describe the second full moon in a month that has two full moons.</p>



<h2 class="wp-block-heading" id="h-get-set-for-the-show">Get set for the show</h2>



<p>To make the most of this experience, find a spot with a clear view of the horizon, like a beach, hill, or open field. If you find yourself in an urban setting, darker skies offer a better view as light pollution can put a damper on the moon's brightness. </p>



<p>To really delve into details like craters, think about bringing binoculars or a telescope. These tools will boost your ability to take in the <a href="https://www.earth.com/news/two-meteor-showers-delta-aquarids-alpha-capricornids-light-up-night-skies-august-2024/" target="_blank" rel="noreferrer noopener">moon's beauty</a> up close. </p>



<p>Carefully picking the right place and equipment will turn this into an unforgettable experience. It will let you forge a deeper connection with the marvels of the night sky.</p>



<h2 class="wp-block-heading" id="h-moonlight-magic">Moonlight magic</h2>



<p>Appreciating these celestial shows can be even more enjoyable once we understand the science behind the moon's light. Moonlight isn't generated by the moon itself. Instead, it’s sunlight reflecting off the moon's surface. </p>



<p>This reflection can alter depending on the moon's phase and position relative to Earth. This, in turn, influences how bright or dim the moon appears in our night sky. </p>



<p>For instance, during a supermoon, when the moon is at its perigee, the sunlight that reaches us is maximized due to the moon's closeness to Earth. </p>



<p>This results in a breathtaking show that grabs attention worldwide. The interplay of light and distance creates an ever-evolving sight that continues to spark scientific interest and artistic inspiration.</p>



<h2 class="wp-block-heading" id="h-dance-between-earth-and-moon">Dance between Earth and moon</h2>



<p>The distance between Earth and the moon is always changing because of the moon's elliptical orbit around our planet. This fluctuation can range up to around 226,000 miles. </p>



<p>When the moon is nearest to Earth, it appears larger and brighter, and when it's farthest, it appears smaller and dimmer. If the moon's orbit were a perfect circle, we would not see these changes in size and brightness during a full moon.</p>



<p>Understanding this phenomenon sheds light on the dynamic relationship between Earth and its natural satellite, showing us the meticulous ballet of <a href="https://www.earth.com/news/mars-and-jupiter-will-have-a-close-encounter-in-the-sky-this-week/" target="_blank" rel="noreferrer noopener">celestial bodies</a> in our solar system.</p>

Tonight's rare 'supermoon blue moon' is the biggest and brightest of 2024

The heavens are getting ready to roll out a stunning...

<p>We can often find the stunning beauty and fascination that nature has to offer right in our own backyard. However, could there be a plant lurking in your outdoors that's not quite as benign as it appears? </p>



<p>Recently, researchers delved into the dark side of the <a href="https://www.earth.com/news/what-are-the-biggest-drivers-of-biodiversity-loss/" target="_blank" rel="noreferrer noopener">plant world</a> where a (commonly found) toxic specimen is causing quite a stir -giant hogweed.</p>



<h2 class="wp-block-heading" id="h-giant-hogweed-the-toxic-plant">Giant hogweed: The toxic plant</h2>



<p>Giant hogweed, a plant that comfortably sprouts 10 to 20 feet high, seems like just another pretty flora - striking in appearance and sporting a radiant white bloom in summer.</p>



<p>As it turns out, this attractive facade conceals a weapon - sap laden with toxins. This sap can cause painful blisters, but it doesn't stop there. </p>



<p>The sap amalgamates with your skin's DNA. The UV rays from the sun then aid in the demolition of these DNA molecules. So, while your eyes enjoy the spectacle, your DNA suffers an onslaught.</p>



<h2 class="wp-block-heading" id="h-understanding-invasive-giant-hogweed">Understanding invasive giant hogweed</h2>



<p>Giant hogweed (<em>Heracleum mantegazzianum</em>) has thick, hollow stem usually sports dark reddish-purple spots and can grow up to 4 inches in diameter, covered in fine white hairs that make it stand out in any landscape.</p>



<p>The plant boasts massive leaves that can stretch up to 5 feet wide. These deeply lobed and sharply serrated leaves form a rosette pattern at the base, adding to its imposing presence. </p>



<p>In late spring to early summer, giant hogweed bursts into bloom with expansive, umbrella-shaped clusters of small white flowers, known as umbels. Each plant has the potential to produce thousands of seeds, showcasing its impressive reproductive capabilities.</p>



<p>The seeds themselves are light brown, oval-shaped, and flat, featuring ridged edges. A single plant can generate up to 50,000 seeds, which get dispersed by wind, water, or even human activity. They can linger in the soil for several years, complicating efforts to control this invasive species.</p>



<p>Unfortunately, its rapid growth and large size enable it to outcompete native plants, threatening biodiversity and disrupting ecosystems. Its deep roots can also destabilize soil, increasing the risk of erosion, especially near waterways.</p>



<h2 class="wp-block-heading" id="h-growing-concern-of-toxic-plants">Growing concern of toxic plants</h2>



<p>This is not some isolated, once-in-a-blue-moon occurrence. The spread of giant hogweed has triggered warnings in several regions, including New York. The impact of this <a href="https://www.earth.com/news/effective-conservation-efforts-key-to-saving-biodiversity/" target="_blank" rel="noreferrer noopener">invasive species</a> on public health and the environment is profound.</p>



<p>When you brush against this plant, your skin can experience an intense reaction such as blisters, burns, and even DNA damage.</p>



<p>The repercussion of this exposure is immediate and discomforting. Burn-like marks show up within a day, followed by swellings filled with fluid. </p>



<p>Although the irritation subsides over time, the UV sensitivity of the affected areas might persist.</p>



<h2 class="wp-block-heading" id="h-invisible-invader-in-the-united-states">Invisible invader in the United States </h2>



<p>Is that the end of the horror tale? Unfortunately, no. On a microscopic level, the toxins infiltrate your skin cells, causing DNA and cell destruction. This ghastly process results in the burn-like blisters synonymous with the giant hogweed encounter.</p>



<p>This toxic terror is a foreign <a href="https://www.earth.com/news/economic-time-bomb-costs-of-invasive-species-are-greatly-underestimated/" target="_blank" rel="noreferrer noopener">invasive species</a>. Giant hogweed has its roots in the Caucasus Mountains, nestled between Asia and Europe, and Central Asia.</p>



<p>However, its journey to the United States began when it was sown in a New York City garden in 1917. Since then, it has invaded the Northeast, the Great Lakes region, and even Washington and Oregon.</p>



<p>Being <a href="https://www.earth.com/news/scientists-create-plants-that-change-colors-when-toxic-chemicals-are-present/" target="_blank" rel="noreferrer noopener">toxic</a> is not the only claim to fame for the giant hogweed. It's also exceptionally fertile, as each plant is capable of producing up to 100,000 seeds.</p>



<p>This fertility makes it incredibly challenging to remove. Despite the best efforts of the <a href="https://dec.ny.gov" target="_blank" rel="noreferrer noopener">New York Department of Environmental Conservation</a>, these plants are holding their ground in more than a thousand sites across the state.</p>



<h2 class="wp-block-heading" id="h-battling-toxic-and-invasive-giant-hogweed">Battling toxic and invasive giant hogweed</h2>



<p>As the giant hogweed continues to assert its dominance, concerted efforts to manage its spread have become paramount. </p>



<p>Various methods have been employed to combat this invasive species, ranging from mechanical removal to the use of herbicides.</p>



<p>Mechanical removal, while effective, demands caution and protective gear, as the risk of exposure to its toxic sap persists. </p>



<p>Alternatively, herbicides can be used strategically to target the plant while minimizing impact on surrounding ecosystems. However, timing and application must be meticulously controlled to ensure success.</p>



<p>Education plays a vital role in these efforts. Increasing public awareness can help in early identification and reporting, thereby curtailing the plant's spread.</p>



<h2 class="wp-block-heading" id="h-future-of-our-landscapes">Future of our landscapes</h2>



<p>Looking ahead, the battle against giant hogweed requires collective action from communities, policymakers, and environmentalists.</p>



<p>Continued research into effective control strategies is necessary, alongside the collaboration of local agencies to monitor and address outbreaks systematically. </p>



<p>As we continue to enjoy our green spaces, it is crucial to remain informed about local flora and <a href="https://www.earth.com/news/toxic-plants-can-be-easily-confused-with-edible-ones/" target="_blank" rel="noreferrer noopener">report concerning sightings</a>.</p>



<p>By fostering a deeper understanding of our environment and being proactive in our approach to invasive species, we can help preserve the integrity of our natural landscapes for future generations. </p>



<p>The beauty of our surroundings should not come at a hidden cost, and together, we can work to ensure that the tale of giant hogweed concludes with a resounding victory over this botanical intruder.</p>



<h2 class="wp-block-heading" id="h-what-should-you-do">What should you do?</h2>



<p>Considering this alarming scenario, what's your best line of defense if you encounter giant hogweed? First off, report it to the authorities.</p>



<p>In addition, do not try to remove it yourself. If you do come into contact with the plant, wash off the sap immediately, avoid any sunlight exposure, and keep the area covered.</p>



<p>The next time you spot a large plant with spiky leaves and white blossoms, the story of giant hogweed should spring to mind. </p>



<p>This cautionary tale serves to remind us that no matter how alluring, nature has its own rules. Approach with knowledge, respect, and, most importantly, a safe distance.</p>

Rapidly spreading invasive plant alters DNA and causes severe burns

We can often find the stunning beauty and fascination that...

<p>What truly defines our consciousness? How does it arise from mere biological processes? These questions have sparked countless debates and studies. Some fascinating new research in the quantum realm might bring a glimmer of light into this abyss of questions, potentially unraveling the enigma that is human consciousness.</p>



<p>The <a href="https://www.earth.com/news/panpsychism-what-if-all-things-humans-plants-atoms-have-universal-consciousness/" target="_blank" rel="noreferrer noopener">mystery of consciousness</a> has tied us in knots for centuries, captivating philosophers, scientists, and thinkers alike. We marvel at the brilliance of our own minds, exploring the depth of our thoughts, emotions, and experiences, only to find it equally baffling and elusive.</p>



<p>Through neuroscience, psychology, and philosophy, we can begin to piece together the puzzle of what it means to be aware and alive.</p>



<p>Meet Yong-Cong Chen, an esteemed professor from <a href="https://en.shu.edu.cn/" target="_blank" rel="noreferrer noopener">Shanghai University</a> and the Shanghai Center for Quantitative Life Sciences. Chen is dedicated to unraveling those mind-bending questions that keep us awake at night. </p>



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



<p>The greatest challenge in <a href="https://www.earth.com/news/when-do-babies-start-gaining-their-consciousness/" target="_blank" rel="noreferrer noopener">understanding consciousness</a> lies in its inherent complexity. </p>



<p>How do our brains, composed solely of biological tissue, manage to generate intricate processes such as thoughts, emotions, and the remarkable phenomenon of self-awareness? </p>



<p>This perplexing question has intrigued philosophers and scientists for centuries.</p>



<p>While intriguing theories like neural synchronization -- which posits that various regions of the brain collaborate seamlessly -- and neurotransmitter interactions influencing mood and behavior provide valuable insights, they do not offer a comprehensive explanation. </p>



<p>The synchronous <a href="https://www.earth.com/news/where-in-the-brain-does-consciousness-reside-scientists-think-they-might-know/" target="_blank" rel="noreferrer noopener">firing of millions of neurons</a> that creates the rich tapestry of human experience remains a mystery. </p>



<p>Some researchers even speculate that quantum mechanics might hold the key to <a href="https://www.earth.com/news/quantum-consciousness-and-you-what-happens-when-machines-become-sentient/" target="_blank" rel="noreferrer noopener">unraveling the secrets of consciousness</a>. In particular, the fascinating notion of instantaneous communication between particles across vast distances known as <a href="https://www.earth.com/news/elusive-quantum-negative-entanglement-entropy-deciphered-in-the-lab/" target="_blank" rel="noreferrer noopener">quantum entanglement</a>.</p>



<h2 class="wp-block-heading" id="h-exploring-quantum-consciousness-theories">Exploring quantum consciousness theories</h2>



<p>Striding into this relatively unexplored territory, Chen and his team speculated that quantum mechanics, specifically quantum entanglement, could have a role in brain communication. </p>



<p>They have zoomed in on the myelin sheath, a protective layer encasing nerve fibers, which seems to play a huge role in <a href="https://www.earth.com/news/rebooting-the-brain-experts-can-transform-cells-into-neurons/" target="_blank" rel="noreferrer noopener">neuron synchronization</a>.</p>



<p>The myelin sheath, our neural bodyguard, not only shields axons (neuron transmitters) but also boosts neural transmission speed. </p>



<p>However, the puzzle remains unsolved as the neural signals tend to travel slower than sound, prompting us to ask, how do our brains <a href="https://www.earth.com/news/meditation-reveals-common-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">synchronize countless neurons</a> efficiently? Chen and his crew believe quantum entanglement could hold the answer.</p>



<h2 class="wp-block-heading" id="h-studying-consciousness-in-the-quantum-realm">Studying consciousness in the quantum realm</h2>



<p>Chen's team, in their pursuit of answers, treated photons and their surrounding electromagnetic fields in the <a href="https://www.earth.com/news/heart-conditions-linked-hidden-brain-changes/" target="_blank" rel="noreferrer noopener">myelin sheath</a> as quantum entities. </p>



<p>They unearthed that the myelin sheath traps energy within, acting as an electromagnetic cavity, producing highly entangled photons. </p>



<p>These entangled photons defy the basic principles of <a href="https://www.earth.com/news/radical-new-theory-finally-unites-gravity-spacetime-and-the-quantum-realm/" target="_blank" rel="noreferrer noopener">classical physics</a> where changing the state of one photon, would instantly affect the other, regardless of the distance between them.</p>



<p>"We showed that the two photons can indeed have a higher rate of being entangled under certain conditions," Chen explained.</p>



<p>This intriguing discovery implies that our brains might be using quantum mechanics to promote faster <a href="https://www.earth.com/news/zombie-neurons-shed-new-light-on-learning/" target="_blank" rel="noreferrer noopener">neuron communication</a>, potentially rewriting our understanding of neural communication, and ultimately, consciousness.</p>



<h2 class="wp-block-heading" id="h-real-world-implications">Real-world implications</h2>



<p>Imagine if we unraveled the <a href="https://www.earth.com/news/mindfulness-can-lead-to-altered-states-of-consciousness/" target="_blank" rel="noreferrer noopener">mystery of consciousness</a>. It would change the way we understand not only our minds but perhaps offer profound insights into brain diseases, improve brain-machine interfaces, and maybe even advance artificial intelligence. The potential applications of these findings are vast.</p>



<p>Consider the possibility of this photon entanglement extending to potassium ion channels in neurons. This could mean a quantum effect on neuron firing, opening up new perspectives on brain signaling.</p>



<p>Chen highlights, "at this early stage, our primary goal is to identify possible mechanisms of <a href="https://www.earth.com/news/social-bonding-can-positively-shape-the-success-of-a-group/" target="_blank" rel="noreferrer noopener">neural synchronization</a>, which affects numerous neurobiological processes." </p>



<p>His work is a testament to the boundless mysteries that our brains hold and the extent of our efforts to understand it.</p>



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



<p>Our brains, the most complex organs in our bodies, continue to amaze and challenge us. Chen's research offers a new lens to view these wonders, suggesting that <a href="https://www.earth.com/news/impossibility-paradox-calculating-incalculable-quantum-realm-particles/" target="_blank" rel="noreferrer noopener">quantum mechanics might be a silent player</a> in our brain communication. </p>



<p>As we grapple with consciousness's intricacies, mind-bending research like Chen's reminds us of the limitless possibilities that stretch before us.</p>



<p>Could quantum mechanics and the human brain be entwined in ways we never imagined? The story of the origin and emergence of consciousness is only just beginning.</p>



<p>The full study was published in the journal <em><a href="https://link.aps.org/doi/10.1103/PhysRevE.110.024402">Physical Review E</a></em>.</p>

Quantum connection behind brain signals and human consciousness

What truly defines our consciousness? How does it arise from...

<p>Over 700 million years ago, our planet experienced a deep freeze known as Snowball Earth. During this time, ice nearly covered the entire globe, setting the stage for life as we know it. </p>



<p>Recent research from University College London (UCL) has revealed a significant rock formation that may hold the most complete record of this icy chapter in Earth's history.</p>



<p>The Port Askaig Formation spans across Ireland and Scotland, with rock layers reaching up to 1.1 kilometers thick. </p>



<p>These rocks likely formed during the Sturtian glaciation, one of the planet's most severe ice ages, which occurred between 662 and 720 million years ago. This period is thought to have been crucial for the <a href="https://www.earth.com/news/past-snowball-earth-conditions-drove-evolution-complex-multicellular-life/" target="_blank" rel="noreferrer noopener">evolution of complex, multicellular life</a>.</p>



<p>Researchers believe these ancient rocks could signal the beginning of the Cryogenian Period. In geology, this important marker is known as a Global Boundary Stratotype Section and Point (GSSP), often symbolized by a "golden spike" embedded in the rock.</p>



<h2 class="wp-block-heading" id="h-glimpse-into-the-snowball-earth-record">Glimpse into the Snowball Earth record</h2>



<p>One exposed outcrop of the formation, found on the Scottish islands known as the Garvellachs, is unique as it shows the transition into Snowball Earth from a previously warm, tropical environment. </p>



<p>Other rocks formed at a similar time, such as those in North America and Namibia, are missing this critical transition.</p>



<p>“These rocks record a time when <a href="https://www.earth.com/news/earth-was-a-giant-snowball-700-million-years-ago-and-now-scientists-know-why/" target="_blank" rel="noreferrer noopener">Earth was covered in ice</a>. All complex, multicellular life, such as animals, arose out of this deep freeze, with the first evidence in the fossil record appearing shortly after the planet thawed,” explained Senior Author Professor Graham Shields, of <a href="https://www.ucl.ac.uk/earth-sciences/" target="_blank" rel="noreferrer noopener">UCL Earth Sciences</a>.</p>



<h2 class="wp-block-heading" id="h-from-warm-seas-to-ice-age">From warm seas to Ice-age</h2>



<p>The layers of rock exposed on the Garvellachs are globally unique. </p>



<p>Beneath the rocks laid down during the frigid Sturtian glaciation, 70 meters of older carbonate rocks formed in tropical waters showcase a time of flourishing cyanobacterial life that gradually cooled, ending a billion-year span of <a href="https://www.earth.com/news/summers-seasons-warm-faster-than-winters-earths-climate-history/" target="_blank" rel="noreferrer noopener">Earth's temperate climate</a>. </p>



<p>“Most areas of the world are missing this remarkable transition because the ancient glaciers scraped and eroded away the rocks underneath, but in Scotland, by some miracle, the transition can be seen,” said Elias Rugen, the study's first author and a PhD candidate at UCL Earth Sciences.</p>



<h2 class="wp-block-heading" id="h-snowball-earth-and-the-cryogenian-period">Snowball Earth and the Cryogenian period</h2>



<p>The Sturtian glaciation, which lasted approximately 60 million years, was one of two big freezes during the Cryogenian Period (635 to 720 million years ago). </p>



<p>For billions of years before this period, life consisted only of <a href="https://www.earth.com/news/organisms-called-protosterol-biota-lived-1-6-billion-years-ago/" target="_blank" rel="noreferrer noopener">single-celled organisms</a> and algae. </p>



<p>After this period, complex life emerged rapidly, with most animals today similar in fundamental ways to <a href="https://www.earth.com/news/ecosystem-behavior-earth-first-sea-creatures-stirring-water-drove-evolution/" target="_blank" rel="noreferrer noopener">life forms that evolved</a> over 500 million years ago.</p>



<p>One theory is that the extreme cold may have prompted the emergence of cooperation among single-celled organisms, leading to the formation of multicellular life. </p>



<p>“The retreat of the ice would have been catastrophic. Life had been used to tens of millions of years of deep freeze. As soon as the world warmed up, all of life would have had to compete in an arms race to adapt. Whatever survived were the ancestors of all animals,” Professor Shields added.</p>



<h2 class="wp-block-heading" id="h-legacy-of-the-port-askaig-formation">Legacy of the port Askaig formation</h2>



<p>For the new study, the research team collected samples of sandstone from the 1.1km-thick Port Askaig Formation and the older, 70-meter-thick Garbh Eileach Formation underneath. </p>



<p>They analyzed durable minerals called zircons within the rock, which contain the radioactive element uranium. </p>



<p>By examining the decay of uranium to lead, the researchers precisely dated the rocks to between 662 and 720 million years ago.</p>



<p>The researchers believe these new age constraints may support the case for the site to be declared a marker for the start of the Cryogenian Period. </p>



<p>Such markers, known as Global Boundary Stratotype Section and Point (GSSP) or 'golden spikes,' often attract international visitors and can even lead to the establishment of museums at these geological landmarks.</p>



<p>A group from the International Commission on Stratigraphy, part of the International Union of Geological Sciences, visited the Garvellachs in July to assess the potential for a golden spike on the archipelago. Currently, these islands are accessible only by chartering a boat or by sailing or kayaking to them.</p>



<h2 class="wp-block-heading" id="h-snowball-earth-s-past-holds-the-key-to-earth-s-future">Snowball Earth's past holds the key to Earth's future</h2>



<p>To sum it all up, the discovery of the Port Askaig Formation highlights one of Earth’s most amazing periods, giving us a rare look at a time when our planet was completely frozen. </p>



<p>This formation shares a story of survival and how complex life emerged from tough conditions. As researchers keep exploring this site, they’re uncovering insights that help us understand life's resilience and adaptability.</p>



<p>If the Port Askaig Formation gets designated as a golden spike, it could put this remote Scottish spot on the map internationally. This recognition would not only secure its place in the geological record but also remind us of the importance of preserving and studying our planet’s ancient past. </p>



<p>In a time when we’re facing rapid environmental changes, these insights serve as a reminder of the delicate balance that supports life on Earth and the significant effects climate shifts can have on our future.</p>



<p>The study involved researchers from UCL, the <a href="https://en.unimib.it/" target="_blank" rel="noreferrer noopener">University of Milano-Bicocca</a>, Italy, and <a href="https://www.bbk.ac.uk/" target="_blank" rel="noreferrer noopener">Birkbeck University</a> of London. The work was funded by the Natural Environment Research Council (NERC).</p>



<p>The full study was published in the journal <em><a href="https://chooser.crossref.org/?doi=10.1144%2Fjgs2024-029" target="_blank" rel="noreferrer noopener">Journal of the Geological Society</a></em>.</p>

'Golden spike' discovered in rock formation reveals when Earth became a snowball

Over 700 million years ago, our planet experienced a deep...

<p>Life on Earth was once ruled by the small, single-celled organisms swimming in the vast oceans. For an epoch, these tiny powerhouses were the kings and queens of the world, dominating for well over a billion years. Then came the period known as "Snowball Earth" that changed everything.</p>



<p>The reign of these <a href="https://www.earth.com/news/cyanobacteria-may-shed-new-light-on-the-history-of-life-on-earth/" target="_blank" rel="noreferrer noopener">single-celled organisms</a> was seemingly endless, until Snowball Earth turned all known models of life upside down, roughly 700 million years ago.</p>



<p>This icy era was no ordinary winter. The entire globe was ensnared in such <a href="https://www.earth.com/news/earth-was-a-giant-snowball-700-million-years-ago-and-now-scientists-know-why/" target="_blank" rel="noreferrer noopener">extreme glaciation conditions</a> that even the equator may have been blanketed in ice. </p>



<p>However, it was during this frigid epoch that a marvel of evolution occurred -- the birth of multicellular organisms.</p>



<h2 class="wp-block-heading" id="h-multicellular-life-and-the-oxygen-paradox">Multicellular life and the oxygen paradox</h2>



<p>One of the biggest enigmas in biology is the sudden emergence and dominance of <a href="https://www.earth.com/news/fossils-capture-a-turning-point-in-the-evolution-of-life/" target="_blank" rel="noreferrer noopener">multicellular life</a>. Imagine a world where single-celled eukaryotes (organisms with intricate cells containing a nucleus) were the unrivaled rulers. </p>



<p>Then, in the wink of a geological eye, multicellular life blossomed amid the frosty reign of Snowball Earth. The prevailing theory suggests that oxygen levels had to reach a critical point before single cells could band together, forming multicellular colonies. </p>



<p>However, this theory falls short of explaining why the ancestors of today's animals, plants, and fungi all popped up simultaneously during this icy epoch.</p>



<p>The answer to this billion-year-old riddle has led researchers to delve deeper into the <a href="https://www.earth.com/news/snowball-earth-may-not-have-been-frozen-solid/" target="_blank" rel="noreferrer noopener">unique conditions</a> of Snowball Earth. </p>



<p>One such scientist is William Crockett, a former Undergraduate Complexity Researcher at <a href="https://www.santafe.edu/" target="_blank" rel="noreferrer noopener">Santa Fe Institute</a>, who put forward a compelling new model.</p>



<h2 class="wp-block-heading" id="h-snowball-earth-and-the-viscosity-factor">Snowball Earth and the viscosity factor</h2>



<p>Crockett's study sheds light on the Snowball Earth mystery. The research team suggests that the physical conditions during this icy period, such as the increased viscosity of the oceans and scarcity of resources, might have led to the rise of <a href="https://www.earth.com/news/cannibalism-cellular-level-common-across-various-life-forms/" target="_blank" rel="noreferrer noopener">multicellular life</a>.</p>



<p>During this glaciated period, oceans were choked with ice, inhibiting sunlight, and hindering photosynthesis. These conditions led to a significant reduction in nutrients, creating a struggle for survival. </p>



<p>According to the study, larger organisms, capable of filtering more water and seizing scarce resources, would have had a significant edge over their smaller, single-celled counterparts.</p>



<p>Crockett observes, "It seems almost counterintuitive that these really harsh conditions, this frozen planet, could actually select for larger, more <a href="https://www.earth.com/news/rewrite-the-textbooks-life-on-earth-did-not-arise-due-to-increased-oxygen-levels/" target="_blank" rel="noreferrer noopener">complex organisms</a>, rather than causing species to go extinct or reduce in size."</p>



<h2 class="wp-block-heading" id="h-survival-of-the-largest-early-animals-thrive">Survival of the largest: Early animals thrive</h2>



<p>By developing scaling theories, the researchers modeled how <a href="https://www.earth.com/news/organisms-called-protosterol-biota-lived-1-6-billion-years-ago/" target="_blank" rel="noreferrer noopener">different organisms</a> would have fared during these harsh conditions. </p>



<p>The findings indicated that early ancestors of animals, similar to modern-day swimming algae that consume prey instead of relying on <a href="https://www.earth.com/news/key-to-life-on-earth-photosynthesis-begins-on-the-quantum-level-with-a-single-photon/" target="_blank" rel="noreferrer noopener">photosynthesis</a>, would have prospered in this freezing environment. </p>



<p>In stark contrast, single-celled organisms that depend on diffusion for movement and feeding, such as bacteria, may have shrunk in size. </p>



<p>These findings highlight the selective pressure of environmental conditions during Snowball Earth, favoring larger, more complex organisms, and paving the way for <a href="https://www.earth.com/news/animals-exist-today-ediacaran-period-earth-weak-magnetic-field/" target="_blank" rel="noreferrer noopener">multicellular life’s emergence</a>.</p>



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



<p>The melting of Snowball Earth’s icy grip marked a new era for the newly evolved multicellular organisms. Liberated from the icy world's constraints, they diversified, leading to the wide variety of life we see today.</p>



<p>"The world is different after Snowball Earth because there's a new form of life on the planet," explains SFI Professor Christopher Kempes, the senior author of the study. </p>



<p>"Our research suggests that these pivotal moments in Earth's history are not random occurrences, but rather predictable outcomes of planetary evolution." </p>



<p>By understanding these patterns, scientists can gain insight into the fundamental processes that shape life's journey from simple beginnings to <a href="https://www.earth.com/news/rna-world-unraveling-mysteries-life-origin/" target="_blank" rel="noreferrer noopener">complex ecosystems</a> and even intelligent civilizations.</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>

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

<p>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>
