<p>A new study by researchers from the University of Leeds, University of Oxford, and <a href="https://www.ucl.ac.uk" target="_blank" rel="noreferrer noopener">University College London</a> provides fresh insight. </p>

<p>The makeup of Earth’s <a href="https://www.earth.com/news/earths-inner-core-proven-to-be-rapidly-changing-and-now-rotating-backwards/">core</a> determines not only its density but also its thermal and magnetic behavior. </p>



<p>Seismology shows that the core is less dense than pure iron, meaning lighter elements must be present. Candidates like silicon, sulphur, oxygen, and carbon have all been considered.</p>



<p>The latest simulations show that carbon, in particular, may have been essential. Without it, the inner core’s crystallization would have required impossible conditions, making its very existence a mystery.</p>

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



<p>Liquids rarely freeze solid the instant they cool past their <a href="https://www.britannica.com/science/melting-point" target="_blank" rel="noreferrer noopener">melting point</a>. Instead, they must be supercooled, chilled further before crystals can form. </p>



<p>For molten iron alone, estimates suggested that a massive 800 to 1000 °C (1472 to 1832 °F) of supercooling would be needed.</p>



<p>If that had occurred, the consequences for our planet would have been dramatic. </p>



<p>The inner core would have grown far too quickly, disrupting the delicate balance of heat flow inside <a href="https://www.earth.com/news/earths-inner-core-is-not-solid-it-is-shape-shifting-time-for-textbooks-to-be-rewritten/">Earth</a> and destabilizing the magnetic field that protects life from harmful solar and cosmic radiation.</p>



<p>Scientists know this did not happen. Geophysical evidence points instead to a modest level of supercooling, limited to about 250 °C (482 °F). </p>



<p>That small difference between theoretical predictions and observational reality has puzzled researchers for decades.</p>



<p>This contradiction, known as the inner core nucleation paradox, continues to inspire debate, experiments, and advanced simulations aimed at uncovering the true chemistry of Earth’s deepest layers.</p>



<h2 class="wp-block-heading" id="h-simulating-the-impossible">Simulating the impossible</h2>



<p>To resolve the paradox, the research team ran atomic-scale simulations of iron mixed with different light elements. </p>



<p>They tested silicon, sulfur, oxygen, and carbon, and watched how each affected the first step of freezing: nucleation.</p>



<p>“Each of these elements exists in the overlying <a href="https://www.earth.com/news/how-an-ocean-of-fire-shaped-early-earths-core-according-to-a-new-study/">mantle</a> and could therefore have been dissolved into the core during Earth’s history,” explained co-author Associate Professor Andrew Walker from the <a href="https://www.ox.ac.uk" target="_blank" rel="noreferrer noopener">University of Oxford</a>.</p>



<p>“As a result, these could explain why we have a solid inner core with relatively little supercooling at this depth. The presence of one or more of these elements could also rationalize why the core is less dense than pure iron, a key observation from seismology.”</p>

<h2 class="wp-block-heading" id="h-carbon-drives-earth-s-core-freezing">Carbon drives Earth's core freezing</h2>



<p>The simulations revealed that silicon and sulfur actually hindered freezing, which would have increased the supercooling requirement. Carbon, however, had the opposite effect.</p>



<p>With 2.4 % carbon, the required supercooling dropped to about 420 °C (788 °F). Still too high, but much closer to reality. </p>



<p>Extrapolating further, a carbon content of 3.8 % reduced the figure to 266 °C (511 °F), which is consistent with geological evidence.</p>



<p>This makes carbon the only element so far shown to both enable nucleation and align with seismic observations.</p>



<h2 class="wp-block-heading" id="h-no-seeds-needed">No seeds needed</h2>



<p>Unlike hail forming around dust in clouds, Earth’s <a href="https://www.earth.com/news/scientists-discover-how-gold-reaches-earths-surface-from-the-mantle/">core</a> appears to have frozen without “nucleation seeds.” </p>



<p>Tests of possible seed materials, like oxides or metals, show they would melt or dissolve before reaching the center. That leaves chemistry itself, specifically the presence of carbon, as the driver of solidification.</p>



<p>“It is exciting to see how atomic scale processes control the fundamental structure and dynamics of our planet," said lead author Dr. Alfred Wilson from the <a href="https://www.leeds.ac.uk" target="_blank" rel="noreferrer noopener">University of Leeds</a>. </p>



<p>"By studying how Earth’s inner core formed, we are not just learning about our planet’s past. We’re getting a rare glimpse into the chemistry of a region we can never hope to reach directly and learning about how it could change in the future.”</p>

<p>This enables a better understanding of how Earth’s deep engine has evolved to influence the magnetic field, surface conditions, and even the long-term habitability of our planet.</p>

Scientists have changed their minds again about the composition of Earth's core

Far beneath our feet, beyond the Earth's rocky mantle and molten outer core, lies a dense, solid sphere of iron and other elements like carbon. This inner core is Earth’s deepest secret, shaping the magnetic field that shields our planet. Yet, scientists still puzzle over how it first formed and what ingredients allowed it to crystallize. A new study by researchers from the University of Leeds, University of Oxford, and University College London provides fresh insight. Their findings reveal that carbon may have been the key element...

<p>Our brain's ability to absorb fresh information - whether that means mastering a new task at work, memorizing the refrain of a song, or navigating unfamiliar streets - depends on a remarkable talent for neural self‑reinvention. </p>



<p>Every time we practice something novel, millions of tiny contacts between nerve cells subtly adjust their strength and neurons use multiple mechanisms to store knowledge.</p>



<h2 class="wp-block-heading" id="h-mystery-of-how-the-brain-learns">Mystery of how the brain learns</h2>



<p>Some connections, called <a href="https://www.earth.com/news/electrical-synapses-are-key-to-decision-making-in-animal-brains/" target="_blank" rel="noreferrer noopener">synapses</a>, amplify their signals to stamp in crucial details; others turn down the volume to clear away noise. Collectively these shifts are known as synaptic plasticity and for decades neuroscientists have cataloged dozens of molecular pathways that can nudge a synapse up or down.</p>



<p>What has remained mysterious is how the brain decides which synapses to retune and which to leave alone. Each synapse has access only to its own local activity, yet the organism as a whole must reinforce precisely those connections that improve future behavior.</p>



<p>This computational puzzle - nicknamed the “credit assignment problem” - is roughly analogous to an ant colony whose workers know only their immediate chores, yet somehow build an efficient nest. </p>



<p>A new study from the <a href="https://www.ucsd.edu/" target="_blank" rel="noreferrer noopener">University of California San Diego</a> now offers an unexpected solution and challenges long‑held assumptions about how neurons <a href="https://www.earth.com/news/neurons-can-predict-human-speech-before-we-say-a-word/" target="_blank" rel="noreferrer noopener">learn</a>.</p>



<h2 class="wp-block-heading" id="h-unprecedented-look-at-learning">Unprecedented look at learning</h2>



<p>To tackle the problem, postdoctoral researcher William Wright and colleagues Nathan Hedrick and Takaki Komiyama turned to state‑of‑the‑art brain‑imaging technology. </p>



<p>Leveraging two‑photon microscopy - a technique that can record activity deep inside living tissue with single‑synapse resolution - the team observed the brains of mice while the animals acquired a new motor skill.</p>



<p>Over multiple training sessions the microscope tracked both the incoming “input” spines on each neuron’s dendrites and the outgoing “output” firing patterns of the same cell. Achieving such granular detail required several years of technical refinement, funded primarily through <a href="https://www.nih.gov/" target="_blank" rel="noreferrer noopener">National Institutes of Health</a> research and training grants. </p>



<p>The investigators combined genetically encoded fluorescent sensors, robotics to stabilize the mouse’s head, and custom analysis software capable of aligning thousands of microscopic images collected over days and weeks. The payoff was an unprecedented movie of learning unfolding in real time.</p>



<h2 class="wp-block-heading" id="h-the-brain-changes-as-we-learn">The brain changes as we learn</h2>



<p>Conventional wisdom has treated a neuron as if it obeys a single plasticity rule throughout its structure. If a particular pattern of electrical spikes strengthens one synapse on a cell, the same pattern should have a similar effect elsewhere on that neuron.</p>



<p>Yet the scientists discovered a very different scenario. They found that separate compartments of the same neuron - such as dendritic branches pointing toward different input sources - could follow distinct learning rules simultaneously.  </p>



<p>One group of synapses might strengthen when the cell fired, another group might weaken under identical circumstances, and a third set might remain unchanged. “When people talk about synaptic plasticity, it’s typically regarded as uniform within the brain,” Wright explained. </p>



<p>“Our research provides a clearer understanding of how synapses are being modified during <a href="https://www.earth.com/news/variable-learning-the-key-to-more-effective-study-habits/" target="_blank" rel="noreferrer noopener">learning</a>, with potentially important health implications since many diseases in the brain involve some form of synaptic dysfunction.”</p>



<p>The patterns were robust across multiple mice and persisted after the animals had mastered the task, suggesting the brain intentionally segregates information streams and applies custom rule sets depending on location. In computational terms, a single neuron acts more like a multi‑core processor executing parallel algorithms than a simple on‑off relay.</p>



<h2 class="wp-block-heading" id="h-neurons-are-multi-tasking">Neurons are multi-tasking </h2>



<p>Because each neurite compartment appears to evaluate its performance locally, the broader credit assignment mystery takes on a new complexion. Instead of requiring a global scoreboard that distributes reinforcement back to every contributing synapse, the neuron itself can run several internal scoreboards at once - one per compartment.</p>



<p>“This discovery fundamentally changes the way we understand how the brain solves the credit assignment problem, with the concept that individual neurons perform distinct computations in parallel in different subcellular compartments,” said senior author Takaki Komiyama, a neurobiologist at UC San Diego.</p>



<p>In other words, the ant colony analogy breaks down at the level of a single worker. Each ant, or each compartment, carries its own tiny map of colony objectives, drastically simplifying how useful modifications are selected during learning.</p>



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



<p>Most modern artificial neural networks rely on a single learning rule - back propagation - applied uniformly across all units. The new biological data suggest a richer palette could yield more efficient or flexible machines.</p>



<p>Future <a href="https://www.earth.com/news/can-ai-systems-learn-like-the-human-brain/" target="_blank" rel="noreferrer noopener">AI</a> architectures might assign different plasticity schemes to distinct dendrite‑like structures within a single node, enabling networks to solve complex problems without cumbersome global error signals.</p>



<p>Engineers already explore approaches such as local learning rules and neuromorphic dendrites, but the UC San Diego results provide empirical evidence that nature has long exploited such diversity. </p>



<p>Designing hardware or software that mimics compartment‑specific learning could improve energy efficiency, accelerate adaptation, or boost robustness in changing environments.</p>



<h2 class="wp-block-heading" id="h-a-new-look-at-neurological-disorders">A new look at neurological disorders </h2>



<p>On the medical front, many neurological and psychiatric disorders - from addiction and post‑traumatic stress disorder (<a href="https://www.earth.com/news/witnessing-trauma-may-cause-ptsd-in-a-different-way/" target="_blank" rel="noreferrer noopener">PTSD</a>) to Alzheimer’s disease and autism - involve maladaptive synaptic plasticity. </p>



<p>By revealing that neurons adjust different sets of synapses under separate guidelines, the study offers clinicians fresh targets.</p>



<p>Drugs or stimulation protocols might be tuned to specific compartments, minimizing side effects compared with blanket interventions.</p>



<p>“This work is laying a potential foundation of trying to understand how the brain normally works to allow us to better understand what’s going wrong in these different diseases,” Wright noted.</p>



<p>For example, selectively dampening overactive compartments in fear‑related circuits could reduce traumatic memories. This would not impair other cognitive functions.</p>



<h2 class="wp-block-heading" id="h-research-on-how-the-brain-learns">Research on how the brain learns</h2>



<p>Having demonstrated that neurons juggle multiple instructional manuals, the researchers aim to decode the biochemical tags that assign each synapse to a particular rule set. </p>



<p>Are different neurotransmitter receptors responsible? Do local glial cells or gene‑expression profiles dictate the choice? And how do neurons coordinate compartment decisions to achieve a coherent behavioral output?</p>



<p>Answering these questions will require even finer imaging tools, genetic manipulations that label specific compartments, and sophisticated computational models. Yet the core insight remains: a single neuron is not a one‑rule machine but a mosaic of learning specialists. </p>



<p>Recognizing that complexity pushes neuroscience closer to deciphering the full score of the brain’s symphony of adaptation - and opens new avenues for treating disorders and crafting smarter artificial minds.</p>



<p>The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.ads4706" target="_blank" rel="noreferrer noopener"><em>Science</em></a>.</p>

How the brain learns: Study reveals an unexpected twist

Our brain's ability to absorb fresh information - whether that...

<p>Scientists have long puzzled over why Mars, once protected by a global magnetic field like Earth, now shows only a magnetic imprint mostly concentrated in the planet’s southern hemisphere. </p>



<p>A new study from the <a href="https://ig.utexas.edu/" target="_blank" rel="noreferrer noopener">University of Texas Institute for Geophysics</a> (UTIG) offers a compelling explanation: perhaps <a href="https://www.earth.com/news/mars-captured-in-true-color-like-youve-never-seen-the-red-planet-before/" target="_blank" rel="noreferrer noopener">Mars</a>’ ancient magnetic field was one-sided from the start.</p>



<p>The experts present a model showing that a hemispheric, or one-sided, magnetic field could have emerged if Mars’ core had been entirely liquid during the time its magnetic field was active.</p>



<h2 class="wp-block-heading" id="h-a-mystery-buried-in-martian-rock"><a></a>A mystery buried in Martian rock</h2>



<p>Today, Mars does not have a global <a href="https://www.earth.com/news/earths-magnetic-field-has-a-dent-and-nasa-is-watching-closely/" target="_blank" rel="noreferrer noopener">magnetic field</a>. However, scientists believe that billions of years ago, the planet did possess one. It was likely generated by a planetary dynamo - a self-sustaining process powered by the movement of molten metal within Mars’s core.</p>



<p>While Earth’s magnetic field wraps around the entire planet, Mars left behind a lopsided magnetic signature. Most of the crustal magnetism - what’s essentially a fossil record of the planet’s magnetic past - is preserved in the southern hemisphere. </p>



<p>For decades, that imbalance has puzzled scientists. Chi Yan, a research associate at UTIG and lead author of the study, believes the explanation may be buried deep within <a href="https://www.earth.com/news/the-internal-structure-of-mars-core-is-finally-revealed/">Mars’ core</a>.</p>



<p>“The logic here is that with no solid inner core, it’s much easier to produce hemispheric (one-sided) magnetic fields,” Yan explained. “That could have implications for Mars’ ancient dynamo and possibly how long it was able to sustain an atmosphere.”</p>



<h2 class="wp-block-heading" id="h-liquid-core-changes-the-game">Liquid core changes the game</h2>



<p>Most prior models of Mars’ ancient magnetic field were based on assumptions drawn from Earth’s internal structure: a solid inner core surrounded by molten metal. But in recent years, that picture of Mars has started to shift.</p>



<p>In particular, <a href="https://www.earth.com/news/nasas-insight-lander-is-still-teaching-us-about-mars-after-its-retirement/" target="_blank" rel="noreferrer noopener">NASA’s InSight mission</a>, which studied Martian seismic activity, revealed that Mars’ core contains more light elements - such as sulfur and oxygen - than previously thought. These lighter elements lower the melting point of the core, making it more likely to be entirely molten.</p>



<p>“If Mars’ core is molten now, it almost certainly would have been molten 4 billion years ago when Mars’ magnetic field is known to have been active,” said study co-author Sabine Stanley, a professor at <a href="https://www.jhu.edu/" target="_blank" rel="noreferrer noopener">Johns Hopkins University</a>.</p>



<p>With a liquid core possibility in mind, the team ran a new set of simulations. Instead of a solid inner core, they modeled a young Mars with a fully liquid core.</p>



<p>The team then added a slight temperature difference between the planet’s northern and southern hemispheres. In the model, the northern mantle was made just a bit hotter than the southern mantle.</p>



<h2 class="wp-block-heading" id="h-heat-flow-shaped-the-magnetic-field">Heat flow shaped the magnetic field</h2>



<p>The results were striking. As the simulation ran, heat from the molten core escaped preferentially through the cooler southern hemisphere. </p>



<p>That focused outflow of heat proved sufficient to power a magnetic dynamo - but only in the south. This simulated southern-hemisphere-only magnetic field matches what we observe today in Martian rock.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2025/04/mars_molten-core_magnetic-field-quirks_illustration_credit-UTexas_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2025/04/mars_molten-core_magnetic-field-quirks_illustration_credit-UTexas_1s.webp" alt="Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics.

<p>“We had no idea if it was going to explain the magnetic field, so it’s exciting to see that we can create a (single) hemispheric magnetic field with an interior structure that matches what InSight told us Mars’ interior is like today,” Stanley said.</p>



<p>These findings suggest that Mars didn’t necessarily have a planet-wide magnetic field that was later erased from its northern hemisphere - as some researchers have proposed. Instead, the field may have always been asymmetrical.</p>



<h2 class="wp-block-heading" id="h-rethinking-the-hemispheric-mystery"><a></a>Rethinking the hemispheric mystery</h2>



<p>The difference between Mars’ northern and southern hemispheres has long intrigued scientists. The north features relatively low, smooth terrain, while the south is higher, more rugged, and more strongly magnetized. </p>



<p>Some earlier theories suggested that massive <a href="https://www.earth.com/news/space-rocks-nasa-dart-asteroid-deflection-mission-may-impact-mars/" target="_blank" rel="noreferrer noopener">asteroid</a> impacts may have obliterated magnetic traces from the northern hemisphere. But the new study offers a different idea: what if the northern rocks were never magnetized in the first place?</p>



<p>“Mars is naturally interesting to look at because it’s like Earth in some ways and it’s the closest planet that we can imagine actually setting up shop on,” said UTIG planetary researcher Doug Hemingway, who was not involved in the study.</p>



<p>“But then, it’s got this dramatic hemispheric dichotomy where the topography, the terrain and the magnetic field of the northern hemisphere and southern hemisphere are dramatically different. Anything that gives a clue at what could account for some of that asymmetry is valuable.”</p>



<h2 class="wp-block-heading" id="h-ancient-mars-and-planetary-habitability">Ancient Mars and planetary habitability</h2>



<p>Understanding how Mars lost its magnetic field is more than just a question of planetary history - it has implications for the planet’s climate and potential for life. A global magnetic field helps shield a planet’s atmosphere from solar wind, the stream of charged particles constantly blowing from the Sun. </p>



<p>When Mars lost its magnetic protection, the atmosphere thinned, <a href="https://www.earth.com/news/wave-ripples-discovered-mars-surface-indicate-liquid-water-present-4-billion-years-ago/" target="_blank" rel="noreferrer noopener">water</a> evaporated, and surface conditions became too harsh for life as we know it. The new research suggests that Mars’ magnetic dynamo may have been patchy from the beginning, raising the possibility that atmospheric loss began earlier than previously thought.</p>



<p>By revealing how a small thermal asymmetry in a planet’s mantle could produce a lopsided magnetic field, the study may also help scientists understand other planetary bodies with unusual magnetic features. This includes the planet Mercury and even some of the moons in our solar system.</p>



<p>As planetary scientists continue to digest InSight’s seismic data and refine their models of Mars’ interior, more findings may be on the way. </p>



<p>For now, this study marks a significant step toward explaining one of the Red Planet’s most persistent mysteries - and suggests that Mars’ inner life may have been every bit as strange as its landscape.</p>

Mars once had a strong magnetic field, but now only traces remain

Scientists have long puzzled over why Mars, once protected by...

<p>In the dense rainforests of the Republic of Congo, western lowland gorillas are often seen foraging through the soil. They were long assumed to be foraging for insects, but recent research has turned this assumption on its head. </p>



<p>The real prize hidden in the dirt is not insects at all, but deer truffles - specifically, a species known as <em>Elaphomyces labyrinthinus</em>.</p>



<p>This revelation not only reshapes our understanding of <a href="https://www.earth.com/news/male-infertility-humans-linked-same-genes-gorilla-small-penises/" target="_blank" rel="noreferrer noopener">gorilla</a> behavior, but also highlights the deep value of traditional ecological knowledge. The research, from the Nouabalé-Ndoki National Park, reveals how primates are deeply connected to their forest environment.</p>



<h2 class="wp-block-heading" id="h-discovery-of-truffle-eating-gorillas">Discovery of truffle-eating gorillas</h2>



<p>The study was led by Gaston Abea, a member of the semi-nomadic Bangombe people and the first Indigenous person in Ndoki to become the lead author of a peer-reviewed scientific paper. </p>



<p>Born in the village of Bomassa, Abea brought together deep cultural understanding, sharp observational skills, and modern scientific methods to uncover the truth behind soil-scratching <a href="https://www.earth.com/news/are-gorillas-self-aware-new-research-challenges-old-assumptions/" target="_blank" rel="noreferrer noopener">gorillas</a>.</p>



<p>Abea spent over a decade working at the Mondika and Goualougo field stations, tracking gorilla behavior. His local tracker background gave him a unique perspective, helping him spot patterns others might miss.</p>



<p>"My people's traditional knowledge of these forests is endangered by modern lifestyles but is proving invaluable in continuing to study and preserve these ecosystems," said Abea.</p>



<p>His work strengthens the growing recognition of Indigenous perspectives in conservation, though academic research still often overlooks them.</p>



<h2 class="wp-block-heading" id="h-truffle-digging-is-a-regular-behavior">Truffle digging is a regular behavior </h2>



<p>To understand this behavior, the researchers conducted daily observations of four different gorilla <a href="https://www.earth.com/news/primate-bonds-are-not-just-about-love-theyre-strategic/" target="_blank" rel="noreferrer noopener">groups</a> across two sites: the Goualougo Triangle and the Djéké Triangle. They observed these groups nearly every day for almost ten years, documenting each instance of soil scratching.</p>



<p>The team also used molecular classification tools to identify the truffles being foraged. They conducted group scans to determine how much time gorillas spent searching for truffles. </p>



<p>Then, the researchers used video observations to measure how efficient the animals were during these foraging bouts. Over time, the pattern became clear: soil scratching was a consistent strategy to find deer truffles, not an aimless search or an insect hunt.</p>



<h2 class="wp-block-heading" id="h-some-gorillas-dig-more-than-others">Some gorillas dig more than others</h2>



<p>Interestingly, not all gorilla groups embraced this <a href="https://www.earth.com/news/primate-bonds-are-not-just-about-love-theyre-strategic/" target="_blank" rel="noreferrer noopener">behavior</a> equally. Soil scratching was most frequent in Buka’s group, followed by Kingo’s and Mététélé’s groups. </p>



<p>In contrast, the Loya-Makassa group rarely engaged in truffle foraging. The behavior’s distribution seems tied partly to the availability of truffles, but not entirely.</p>



<p>Social factors appear to influence the practice as well. In one striking example, an adult female gorilla moved from a group that rarely scratched soil to one that did so almost daily. She soon began to mirror the habits of her new group, suggesting that cultural transmission may shape how gorillas forage.</p>



<p>"This is an exciting finding for our understanding of gorilla foraging behavior," said David Morgan of the <a href="https://www.lpzoo.org" target="_blank" rel="noreferrer noopener">Lincoln Park Zoo</a>, who worked on the study and has spent years researching in Ndoki.</p>



<h2 class="wp-block-heading" id="h-gorillas-carefully-select-truffles">Gorillas carefully select truffles</h2>



<p>One of the most vivid pieces of evidence came from a gorilla named Jeanne. Photographed in the Goualougo Triangle, Jeanne was seen scraping away forest leaf litter with her hands. </p>



<p>Once the gorilla exposed the soil, she pinched her fingers together and brought a small round object - presumably a truffle - to her mouth. This precise motion defined a successful foraging attempt and offered a glimpse into just how deliberate the behavior is.</p>



<p>The study's inclusion in a special issue of the journal <em>Primates</em> marked a milestone. The issue celebrated 25 years of research in the Ndoki forest and brought attention to <a href="https://www.earth.com/news/most-early-primates-lived-in-pairs-and-were-not-solitary-creatures/" target="_blank" rel="noreferrer noopener">behaviors</a> that may have otherwise gone unnoticed.</p>



<h2 class="wp-block-heading" id="h-protecting-truffle-foraging-traditions">Protecting truffle-foraging traditions</h2>



<p>Abea’s findings were incorporated into an ecological impact assessment for the Djéké Triangle.</p>



<p>As a result, conservation managers decided to adjust planned locations for tourism-related infrastructure. The aim was to protect areas where truffle foraging occurs regularly, ensuring this unique behavior could continue undisturbed.</p>



<p>"This is Gaston's first article as lead author - a milestone for his career and for our capacity-building efforts," said Morgan. "He is the first research assistant of Indigenous People's origin to become first author, in the Ndoki landscape." </p>



<p>The decision to shift construction plans also highlights a growing understanding of cultural behavior in wildlife. These are not just instinctive acts but socially-influenced practices that may vary by group and change with experience.</p>



<h2 class="wp-block-heading" id="h-from-gorilla-hunters-to-guardians">From gorilla hunters to guardians</h2>



<p>Abea’s story represents more than scientific achievement. It also reflects a cultural shift within his own community. He is one of over 100 Congolese research assistants trained since 2005 at Ndoki, many of whom come from nearby villages and Indigenous Ba’Aka communities.</p>



<p>"Our ancestors used to hunt gorillas, now we protect them, and I hope to inspire other Ba'Akas to do the same," said Abea.</p>



<p>His journey, from a boy in Bomassa to lead author of a major scientific article, mirrors the broader transformation in conservation thinking - one that values the voices and wisdom of local communities.</p>



<h2 class="wp-block-heading" id="h-local-insights-shape-global-research">Local insights shape global research</h2>



<p>While the knowledge about gorillas and foraging for truffles is slowly gaining recognition in the sciences, it still appears too rarely in published research. This study shows how blending local knowledge with science can reveal key insights into animal behavior and ecosystem health.</p>



<p>"This paper shows how much traditional ecological knowledge, scientific research, and conservation can benefit from each other," said Dr. Sydney Ndolo, second author of the paper and now professor of Botany at Université Marien Ngouabi in Brazzaville.</p>



<p>"Local cultures will only survive if they are properly valued, and research is an important means of achieving this."</p>



<p>Through Abea’s work and this study, a hidden part of gorilla life now comes into view - one shaped by truffles, food, forest, and social bonds. And alongside it, the role of Indigenous knowledge in science gains new ground.</p>

<p>Nature-based activities are showing real promise in improving mental health, with visible benefits reported in as little as 12 weeks. </p>



<p>In a recent evaluation of a community program for people with mild to moderate mental health conditions, participants experienced better mood and lower anxiety levels after joining weekly outdoor sessions. </p>



<h2 class="wp-block-heading" id="h-reshaping-mental-health-through-nature"><strong>Reshaping mental health</strong> through nature</h2>



<p>This study is part of the UK government’s larger effort to rethink how mental health care is delivered.</p>



<p>One initiative included setting up seven “test and learn” green social prescribing sites across England. The first site to release its findings comes from Humber and North Yorkshire, where researchers from the <a href="https://www.york.ac.uk/" target="_blank" rel="noreferrer noopener">University of York</a> led the evaluation.</p>



<p>Green social prescribing works by linking people with community-based nature activities instead of, or alongside, traditional medical treatments. </p>



<p>Healthcare professionals can refer patients to activities that bring them outdoors and into contact with the natural world. Though still in the testing phase, the evidence is growing stronger that this approach can be a useful tool in mental health support.</p>



<p>More than 220 participants took part in the Humber and North Yorkshire program. The researchers measured their mental health using the Office for National Statistics’ personal well-being metrics and the Hospital Anxiety and Depression Scale (HADS). The participants ranged in age from 18 to 85 and included people of all genders.</p>



<h2 class="wp-block-heading" id="h-longer-activities-deeper-impact">Longer activities, deeper impact</h2>



<p>The results showed consistent improvement across the board, but participants in longer sessions - typically nine to 12 weeks - saw the most progress.</p>



<p>Activities that involved direct interaction with nature, such as horticulture and care farming, had a bigger effect than sports, crafts, or mindfulness sessions alone.</p>



<p>Professor Peter Coventry from the University of York’s Department of Health Sciences elaborated on the findings.</p>



<p>“We have known for some time that nature has a positive impact on <a href="https://www.earth.com/news/natures-scents-linked-to-improved-health-and-well-being/" target="_blank" rel="noreferrer noopener">health and wellbeing</a>, but in more recent years, a stronger evidence base has grown that proves this to be true for mental health in particular," he said.</p>



<p>“The fact that activities such as gardening, tending allotments, and care farming had the most impact on the participants in our study, demonstrated that it is not just about being passive in nature, but connecting with it in a meaningful way." </p>



<p>Professor Coventry added that spending time in nature with others from your community can ease <a href="https://www.earth.com/news/where-do-fear-and-anxiety-reside-in-the-brain-new-cells-identified/" target="_blank" rel="noreferrer noopener">anxiety</a> and depression by reducing loneliness and fostering connection. Participating in local activities that support the environment can boost mood and promote a sense of belonging.</p>



<h2 class="wp-block-heading" id="h-accessible-and-enjoyable-nature-activities">Accessible and enjoyable nature activities</h2>



<p>The benefits of the program were seen across different age groups and income levels. Of the participants, 65% came from low socioeconomic backgrounds. </p>



<p>Horticulture-based sessions had particularly high attendance, suggesting these activities were both accessible and enjoyable for a wide range of people.</p>



<p>“This intervention might not work for everyone, but through an initial exploratory conversation a social prescriber will discuss with a patient or user of the service if nature-based activities would be suited to them," said Trish Darcy, a research associate from the University’s Mental Health and Addiction Research Group. </p>



<p>"For that choice to happen, we need more investment to support these community-based activities."</p>



<p>“In our study, 65% of participants were from low socioeconomic groups and we now know that not only can it help improve their mental health, but participation was high for horticultural based activities in particular, meaning that not only is it good for the individual, but for the local community environment too."</p>



<h2 class="wp-block-heading" id="h-a-new-green-partner-in-healthcare">A new green partner in healthcare</h2>



<p>The experts conducted the study in partnership with The HEY Smile Foundation and the NHS Humber and North Yorkshire Integrated Care Board. </p>



<p>The research is part of a national cross-government initiative, with backing from DEFRA and several departments and agencies including the Department of Health and Social Care and Sport England.</p>



<p>Dr Hannah Armitt, clinical lead for the regional program, emphasized the potential to bridge medical care with community programs.</p>



<p>“The research conducted in our region has the potential to enhance service delivery by connecting statutory services with local providers of nature-based and <a href="https://www.earth.com/news/outdoor-classes-improve-childrens-mental-health/" target="_blank" rel="noreferrer noopener">outdoor activities</a>," said Dr. Armitt.</p>



<p>“It is important to evidence the potential of green space and nature to ensure clinicians and patients alike can harness the benefits of this wonderful free natural resource we have in abundance in Yorkshire and Humber.”</p>



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



<p>As more of healthcare shifts into the community, the role of local organizations is becoming increasingly important. </p>



<p>Anthony Hurd is the program manager of the <a href="https://www.york.ac.uk/healthsciences/research/mental-health/projects/humber-north-yorkshire-green-social-prescribing/" target="_blank" rel="noreferrer noopener">Humber and North Yorkshire Green Social Prescribing</a>.</p>



<p>“This work has not only shown the positive outcomes that nature-based activities have on mental health, it has also highlighted the role that community-based organizations play in supporting the health and wellbeing of communities," said Hurd.</p>



<p>“As healthcare begins to move more into the community, and with a focus on prevention, the community-based organizations delivering activities such as <a href="https://www.earth.com/news/gardening-is-beneficial-for-physical-and-mental-health/" target="_blank" rel="noreferrer noopener">gardening</a>, care farming, and walking groups need to be recognized as key players in our national health service and be resourced appropriately.”</p>



<p>With continued investment, green social prescribing could become a trusted and lasting part of mental health care across the country - offering hope, healing, and a healthy dose of fresh air.</p>



<p>The research is published in the journal&nbsp;<em><a href="https://onlinelibrary.wiley.com/doi/full/10.1155/hsc/2016261" target="_blank" rel="noreferrer noopener">Health &amp; Social Care in the Community</a></em>.</p>

How nature heals: Outdoor activities greatly improve mental health

Nature-based activities are showing real promise in improving mental health,...

<p>A team of researchers has recently identified the right frontal lobe as a vital part of logical thinking and the ability to tackle new problems.</p>



<p>The study reveals that when the right brain is damaged, people’s capacity for reasoning suffers, implying that this area is central to our day-to-day cognitive functions.</p>



<p>The research was led by experts at <a href="https://www.ucl.ac.uk/" target="_blank" rel="noreferrer noopener">University College London</a> (UCL) and <a href="https://www.uclh.nhs.uk/" target="_blank" rel="noreferrer noopener">University College London Hospitals</a> (UCLH).</p>



<h2 class="wp-block-heading" id="h-damage-to-the-right-frontal-lobe">Damage to the right frontal lobe </h2>



<p>Scientists have long used functional imaging (fMRI) to study cognition in healthy individuals. These studies, however, only show correlations rather than proving which parts of the <a href="https://www.earth.com/news/how-do-specialized-regions-develop-in-the-brain/" target="_blank" rel="noreferrer noopener">brain</a> are essential. </p>



<p>To pinpoint causation, experts rely on lesion-deficit mapping, a technique that examines how specific types of brain damage affect behavior.</p>



<p>Finding sufficient patients with carefully localized right frontal lobe damage can be challenging. The research team overcame that hurdle by enrolling 247 patients with unilateral focal brain lesions (either in the left or right, frontal or posterior regions).</p>



<p>Another 81 healthy adults served as a baseline for comparison. By systematically observing what happens when parts of the brain are damaged, the team could identify the areas indispensable for particular <a href="https://www.earth.com/news/lifestyle-choices-in-young-adulthood-impact-cognitive-ability-in-midlife/" target="_blank" rel="noreferrer noopener">cognitive skills</a>.</p>



<h2 class="wp-block-heading" id="h-measuring-the-brain-s-reasoning-ability">Measuring the brain's reasoning ability</h2>



<p>To measure <a href="https://www.earth.com/news/bumblebees-showcase-smart-logical-reasoning-abilities/" target="_blank" rel="noreferrer noopener">logical reasoning</a>, the researchers created two original tests. One verbal analogical reasoning task asked participants to determine relationships between words. </p>



<p>A question might read: “If Sarah is smarter than Diana, and Sarah is smarter than Heather, is Diana smarter than Heather?” Such questions test one’s ability to deduce logical conclusions from given statements.</p>



<p>The second was a nonverbal deductive reasoning task that required spotting patterns or similarities among shapes, pictures, or numbers. </p>



<p>One sample query stated: “Which set of numbers is 1, 2, 3 most similar to 5, 6, 7 or 6, 5, 7?” The goal was to see how patients reason about relationships without relying on language.</p>



<h2 class="wp-block-heading" id="h-right-brain-is-essential-for-reasoning">Right brain is essential for reasoning </h2>



<p>When the researchers compared test results, one detail stood out: patients with injuries in the right frontal lobe scored significantly worse on both tests than those with lesions in other areas. These patients were about 15% more prone to errors than their counterparts and the healthy controls. </p>



<p>This outcome supports the idea that the right brain is essential for reasoning. It's especially important when interpreting novel information and drawing logical conclusions.</p>



<p>Lead author Joseph Mole of the <a href="https://www.ucl.ac.uk/ion/ucl-queen-square-institute-neurology" target="_blank" rel="noreferrer noopener">UCL Queen Square Institute of Neurology and Department of Neuropsychology</a> emphasized the importance of these findings in spotting reasoning issues early.</p>



<p>“Our study explores how the front right part of the brain helps people think and solve new problems,” said Mole. “It also shows that our two new tests can help detect reasoning problems in individuals with brain damage, improving diagnosis and treatment.”</p>



<h2 class="wp-block-heading" id="h-ties-to-fluid-intelligence"><a></a>Ties to fluid intelligence</h2>



<p>Another important takeaway involves what neuroscientists call fluid <a href="https://www.earth.com/news/every-part-of-the-brain-works-together-to-support-intelligence/" target="_blank" rel="noreferrer noopener">intelligence</a> - our capacity to solve problems in new or unfamiliar situations.</p>



<p>Senior author Lisa Cipolotti, a professor in the same institute at UCLH, noted that the study shows a substantial overlap between the brain networks responsible for fluid intelligence and reasoning. Both networks appear to rely heavily on the right frontal lobe.</p>



<p>The experts used advanced lesion mapping techniques developed by Professor Parashkev Nachev and colleagues at the UCL Queen Square Institute of Neurology. These tools made it possible to explore precisely which portions of the frontal lobe, when damaged, most affect reasoning.</p>



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



<p>The practical impact is significant. Brain injuries from <a href="https://www.earth.com/news/stroke-risk-is-elevated-by-air-pollution-and-traffic-noise/" target="_blank" rel="noreferrer noopener">strokes</a> or tumors can affect daily life in subtle ways. These injuries require the early identification of cognitive deficits. </p>



<p>Many neurological assessments miss right frontal lobe dysfunction because standard tests often focus on memory, language, or motor skills. By contrast, the tasks introduced here specifically examine higher-order reasoning.</p>



<p>The researchers hope that once validated further, these tests can be integrated into clinical settings. For patients, that means more thorough evaluations and, potentially, more focused rehabilitation programs.</p>



<p>If doctors know that a person’s right frontal region has sustained damage, they can anticipate potential problems in logical thinking and develop strategies. This type of cognitive training or specialized therapy will help patients manage symptoms.</p>



<h2 class="wp-block-heading" id="h-more-right-brain-studies-are-needed">More right-brain studies are needed</h2>



<p>Future studies may refine the new tasks to confirm their effectiveness. Additional testing will also detect right-brain deficits across a wider range of patient populations. </p>



<p>Researchers also aim to examine whether training that targets reasoning skills can bolster recovery, potentially improving quality of life for people with frontal lobe injuries.</p>



<p>As this line of research advances, the main lesson is clear: while multiple parts of the brain support different aspects of cognition, the right frontal lobe’s role in reasoning appears especially vital. </p>



<p>For anyone dealing with brain damage - or anyone working to help those who are - this knowledge reshapes how we assess, treat, and ultimately understand the very nature of human thought.</p>



<p>The study is published in the journal <a href="https://academic.oup.com/brain/advance-article/doi/10.1093/brain/awaf062/8104772?searchresult=1" target="_blank" rel="noreferrer noopener"><em>Brain</em></a><em>.</em></p>

Where logic lives: Brain region responsible for reasoning revealed

A team of researchers has recently identified the right frontal...

<p>A honeybee colony seems like a perfect model of unity. Inside the hive, thousands of individuals work in rhythm. Foragers seek nectar. Water collectors hydrate the group. Ventilators fan their wings to cool the brood. Guard bees monitor the entrance. </p>



<p>In this coordinated dance, defense is critical - but personality plays a role, and not all bees choose to sting.</p>



<p>What triggers a bee to sting? Why do some launch themselves into action while others hold back? A new study from the <a href="https://www.uni-konstanz.de/en/" target="_blank" rel="noreferrer noopener">University of Konstanz</a> has explored these questions.</p>



<p>Researchers discovered that not only do <a href="https://www.earth.com/news/why-bees-choose-the-same-flowers-again-and-again/" target="_blank" rel="noreferrer noopener">bees</a> differ in their readiness to sting, but their personalities remain consistent across time and context. The hive may move as one, but decisions start within the individual.</p>



<h2 class="wp-block-heading" id="h-bees-choose-to-sting-or-abstain">Bees choose to sting or abstain</h2>



<p>Doctoral student Kavitha Kannan and neurobiologist Morgane Nouvian led the research at the University of Konstanz. To examine stinging behavior, they needed a reliable group. They selected guard <a href="https://www.earth.com/news/urban-wildflowers-may-be-harming-bees/" target="_blank" rel="noreferrer noopener">bees</a> - those that are naturally closer to the frontlines.</p>



<p>"Basically, you can expect that, simply by the distribution of tasks, a collector will have a different stinging behaviour than a guard. As we wanted to exclude as many influencing factors as possible, this selection was the first logical step. We were then able to gradually test other influencing factors," explained Kannan.</p>



<p>The bees were exposed to a rotating dummy that simulated a predator. The setup allowed repeated trials without harming the <a href="https://www.earth.com/news/world-honey-bee-day-protecting-our-vital-pollinators/" target="_blank" rel="noreferrer noopener">bees</a>. When a bee stings in natural conditions, its stinger is lost and it dies. Here, the bees could engage or abstain multiple times without being harmed. Each action or lack of action was logged.</p>



<h2 class="wp-block-heading" id="h-alarm-scents-don-t-trigger-all-bees">Alarm scents don’t trigger all bees</h2>



<p>In honeybees, a sting is more than a weapon. It is a call to arms. When a <a href="https://www.earth.com/news/artificial-diet-offers-hope-for-saving-endangered-honey-bees/" target="_blank" rel="noreferrer noopener">bee</a> stings, it releases a complex scent signal known as the sting alarm pheromone (SAP), which is primarily composed of iso-amyl acetate (IAA).</p>



<p>This alerts others and encourages them to join in the group defense. As more bees respond, the concentration of IAA increases. Eventually, the response declines - a strategy that may ensure not too many casualties occur. </p>



<p>The study found that SAP does influence bees, but not equally. When exposed to synthetic IAA, bees showed varied reactions. The presence of this signal raised the odds of stinging - but some bees still held back.</p>



<p>"Ultimately, it turned out that although these factors had an influence, they did not impact the predictability of individual stinging behavior," said Nouvian. The bees that chose to sting in one trial often did so again. Others remained passive, regardless of the alarm.</p>



<h2 class="wp-block-heading" id="h-bee-personality-and-stinging-behavior">Bee personality and stinging behavior </h2>



<p>To probe deeper, the researchers tracked <a href="https://www.earth.com/news/world-wildlife-day-2025-a-global-call-to-protect-nature/" target="_blank" rel="noreferrer noopener">bee</a> responses over four repeated trials. The results were striking. Stinging behavior stayed consistent in most individuals. Some stung every time, others never stung, and very few wavered between the two choices.</p>



<p>Even more interestingly, the bees showed greater consistency in behavior when the time between trials was less. This suggests that internal states - perhaps neurological or hormonal - affect decisions. A bee wasn’t flipping a coin each time. It was acting from a semi-stable inner condition.</p>



<p>This state dependence was especially clear when patterns like 1−0−1−0 (stinging, not stinging, stinging, not stinging) were rare. Instead, most bees either kept attacking or kept abstaining. These temporal patterns implied that bees make evaluations based on more than stimulus alone - they carry a mood-like persistence.</p>



<h2 class="wp-block-heading" id="h-peers-aren-t-always-influential">Peers aren't always influential</h2>



<p>Bees are famously social. Still, the presence of another bee had a surprising effect. Rather than encouraging aggression, it reduced it. Pairs of bees were less likely to sting than solo bees, even when faced with the same threat.</p>



<p>This finding challenges currently-held assumptions. Larger groups don’t necessarily mean higher per-bee aggression. In fact, the data aligns with older studies suggesting that larger colonies can show less per-capita defense.</p>



<p>When tested in pairs, real bees stung less than would be predicted by combining data from singles. The effect appeared again, even when both bees could detect IAA. "Pairs as entities did [respond to IAA] (z = −4.327, p &lt; 0.001) … individual bees within pairs (z = −3.68, p &lt; 0.001)," the research paper noted.</p>



<p>Yet, the experts also found that SAP, when released naturally by one bee, could recruit another. The first bee’s sting raised the odds that its partner would follow. But over multiple exposures, this recruitment faded. Responsiveness to IAA dropped, trial by trial. Even social signals have an expiry date.</p>



<h2 class="wp-block-heading" id="h-bees-with-gentle-personalities-sting-less">Bees with gentle personalities sting less</h2>



<p>Another part of the study tested whether bees adjust based on their companions' personalities. After identifying aggressive and gentle bees, the team mixed them in various combinations. Would gentle bees become bolder when placed among aggressive peers?</p>



<p>The answer was no. Bees classified as gentle stayed that way, even in groups full of stingers. Aggressive bees also stayed true to type. The only thing that influenced changes was the SAP level in the arena. More SAP raised the chance of stinging, less reduced it.</p>



<p>These results reveal that honeybees don’t mirror the behavior of those around them. They react to chemical signals, not peer pressure. </p>



<p>“We propose that [Lecomte’s] results were rather the consequence of the reduced group size,” noted the researchers, questioning earlier claims about social inhibition among bees.</p>



<h2 class="wp-block-heading" id="h-bees-resist-group-influence">Bees resist group influence</h2>



<p>What does this mean for our understanding of bee society? This study breaks the idea of a hive acting as one. Each bee carries an internal threshold. That threshold can be nudged by alarm pheromones or dulled by time. It can be lowered by a sense of threat or raised by the presence of others.</p>



<p>Still, the final decision lies with the bee. Stinging isn’t a hive decision. It’s an individual one, shaped by subtle internal states and stable personality.</p>



<p>"That bees stop responding to the SAP but not to the threat itself might be another example of social information being less valued than personal information," the researchers suggested.</p>



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



<p>This study paves the way for deeper research into honeybee behavior. By proving the stability of individual responses, it opens doors for exploring the biological roots of personality. Future work could look into the neurobiology of aggression or the hormonal triggers behind it.</p>



<p>The hive may appear unified, but it is made of diverse minds. Some are ready to die for the colony. Others prefer to wait, even when the alarm is raised. Both types are part of nature’s plan - and together, they balance risk and survival.</p>



<p>The study was published in the journal <em><a href="https://royalsocietypublishing.org/doi/10.1098/rsos.241295" target="_blank" rel="noreferrer noopener">Royal Society Open Science</a>.</em></p>

Bees have unique personalities that determine whether they sting

A honeybee colony seems like a perfect model of unity....

<p>Warm sunshine, soft sand, rolling dunes, and the scent of saltwater can make it easy to forget that every beach getaway relies on a fragile coastal balance. In many regions, that balance is maintained by barrier islands - narrow offshore landforms that serve as nature’s protective shield for inland communities.</p>



<p>Researchers have been investigating how these islands stand firm against <a href="https://www.earth.com/news/star-dunes-lala-lallia-origin-of-earths-largest-desert-sands-mystery-solved/" target="_blank" rel="noreferrer noopener">storms</a> and shifting sea levels. </p>



<p>One such effort has been led by Orencio Duran Vinent, an assistant professor in the <a href="https://engineering.tamu.edu/ocean/index.html" target="_blank" rel="noreferrer noopener">Department of Ocean Engineering</a> at Texas A&amp;M University, who recently studied how an island’s dunes factor into its survival.</p>



<h2 class="wp-block-heading" id="h-dunes-lose-strength-after-storms">Dunes lose strength after storms</h2>



<p>Many coastal communities rely on these islands to slow down erosion and reduce the force of crashing waves. When a major <a href="https://www.earth.com/news/ancient-arabia-was-once-green-and-lush-with-rivers-lakes-and-grasslands/" target="_blank" rel="noreferrer noopener">storm</a> hits, a robust dune system can keep floodwaters and pounding surf from destroying roads and homes.</p>



<p>These dunes work like natural walls, but they need healthy vegetation and enough elevation to hold their ground. A recent <a href="https://www.nature.com/articles/s43247-024-01611-4" target="_blank" rel="noreferrer noopener">paper</a> co-authored by Professor Duran Vinent highlights how storms and sea-level shifts can strip away that plant cover, leaving behind a sandy expanse that gives no real protection.</p>



<p>Once the dunes vanish, the shoreline can begin to lose land at a rapid pace. Some researchers call the bare expanse a barren state, and see it as  marking a low point from which it is difficult to rebound.</p>



<h2 class="wp-block-heading" id="h-tall-dunes-protect-beaches">Tall dunes protect beaches </h2>



<p>Dunes sprout where winds carry sand <a href="https://www.earth.com/news/major-coastal-cities-around-the-world-could-disappear-under-rising-seas-by-2100/" target="_blank" rel="noreferrer noopener">inland</a>, then vegetation anchors those grains in place. That green cover also helps the dunes grow tall enough to act as a sturdy barricade.</p>



<p>When dunes stand at a comfortable height, they are sometimes called the high state, hinting at their role in keeping storm waters at bay. This state represents more than just a sand pile because it supports plants, habitats for local wildlife, and a measure of safety for property owners.</p>



<p>If strong floods sweep over these dunes, they can break apart and lose the vegetation that once solidified the structure. Recovery is possible if the plant life can take root again, but everything depends on how frequently storms bombard the <a href="https://www.earth.com/news/rising-seas-are-already-toppling-coastal-cities/" target="_blank" rel="noreferrer noopener">island</a>.</p>



<h2 class="wp-block-heading" id="h-when-dunes-cannot-recover">When dunes cannot recover</h2>



<p>The recent findings mention a key threshold that separates a healthy dune system from a flattened shoreline. Once the island’s elevation dips below that point, its chances of bouncing back get slimmer with every wave.</p>



<p>If flooding becomes a regular event, the island’s dunes may fail to restore themselves in time. That path leads toward the barren state, in which the dunes lack enough height to safeguard the land behind them.</p>



<p>According to a <a href="https://geonarrative.usgs.gov/cch-bi/" target="_blank" rel="noreferrer noopener">USGS</a> overview, these islands often have two fates: they either hold onto dunes or end up with a barren profile. The difference lies in how quickly vegetation can regrow and how much time passes between storm assaults.</p>



<h2 class="wp-block-heading" id="h-using-nature-to-rebuild-island-dunes">Using nature to rebuild island dunes</h2>



<p>“Modern coastal engineering aims to use natural <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">dynamics</a> rather than concrete constructions, promoting sustainable approaches that include and protect natural systems,” said Professor Duran Vinent.</p>



<p>He and his collaborators see a chance to protect shorelines by working with wind, waves, and plants instead of fighting them head-on.</p>



<p>Interventions could involve planting hardy vegetation or creating gentle slopes that encourage natural sand buildup. Small changes may cut down the frequency of flooding events that push islands toward a barren state.</p>



<p>This approach has gained attention because it costs less in the long run and blends better with local habitats. Some designs even factor in shifting tides and seasonal wind patterns to allow dunes to expand naturally.</p>



<h2 class="wp-block-heading" id="h-dunes-protect-homes-and-tourism">Dunes protect homes and tourism</h2>



<p>From seafood joints to boardwalk shops, many livelihoods sit on the strip of land just behind these protective islands. One big storm could wash away tourism revenue, so local leaders are tuning in to research that highlights these natural defenses.</p>



<p>Whenever dunes flourish, families, restaurants, and entire ecosystems see fewer disruptions from flooding. That stability can help keep roads open, preserve local wildlife, and maintain the scenic charm that folks love.</p>



<p>“A better understanding of the natural dynamics of barrier islands will allow a more timely and effective intervention from coastal engineers, mitigating the risks to coastal infrastructure,” said Duran Vinent.</p>



<p>He noted that this outlook calls for close collaboration among ecologists, geologists, and city planners who share a stake in a stable shoreline.</p>



<h2 class="wp-block-heading" id="h-planning-for-tomorrow">Planning for tomorrow</h2>



<p>Communities that sit near the water can help by limiting construction in sensitive dune zones. Strong dunes form more easily when the beach isn’t overcrowded with walls or heavy equipment that deflect windblown sand.</p>



<p>Local governments might offer guidelines that restrict development near fragile dune ecosystems, thus ensuring that vegetation can grow where it’s needed most. Scientists suggest that these proactive steps stop small storms from doing big harm.</p>



<p>Such measures can be tough decisions for places that depend on beach tourism, but they are essential for long-term safety. If the barrier island dips below that critical elevation, it may never return to a robust dune profile.</p>



<h2 class="wp-block-heading" id="h-monitoring-and-protecting-island-dunes">Monitoring and protecting island dunes</h2>



<p><a href="https://www.careerexplorer.com/careers/coastal-engineer/" target="_blank" rel="noreferrer noopener">Coastal engineers</a> are looking beyond sand and concrete by joining forces with ecologists who track plant growth. That teamwork reveals how dunes can flourish or fail under shifting water levels and changing climates.</p>



<p>“A deeper understanding of the connection between the natural environment and coastal engineering is essential. Fresh insights might help everyone predict which spots are most at risk and how to keep vital vegetation alive,” explained Professor Duran Vinent.&nbsp;</p>



<p>Future research could include advanced computer models that pinpoint weak links in these systems. Better data might also guide decisions on restoring islands that have already flattened out.</p>



<h2 class="wp-block-heading" id="h-restoring-dunes-to-save-islands">Restoring dunes to save islands</h2>



<p>Efforts that restore a failing barrier island offer big payoffs for marine life, beach-goers, and folks who worry about eroding coastlines. These efforts can bring back the taller dunes that block storm surge and protect local homes.</p>



<p>It may take patience, but many see no better way to keep beaches safe and welcoming for future generations. Prioritizing natural systems can save money, preserve landscapes, and keep that salty breeze blowing over sandy shores.</p>



<p>Discussions around climate change make the role of barrier islands even more pressing. Some predict stronger storms and higher sea levels, which calls for solutions that nurture dunes in a natural way.</p>



<p>Research continues to offer new ideas that blend ecological wisdom with engineering know-how. Beach lovers everywhere stand to gain if these protective stretches of sand stay healthy in the face of future challenges.</p>

Healthy dune systems on barrier islands protect coastal cities

Warm sunshine, soft sand, rolling dunes, and the scent of...

<p>Mars is a planet of dramatic contrasts. Roughly one hemisphere of the globe is rugged and ancient, scarred with craters that indicate its age. The other is smoother, having been shaped by lava flows that have covered the underlying rugged surface.</p>



<p>A recent image from the Mars Express spacecraft offers a vivid glimpse of these two faces in a region known as Acheron Fossae. This area lies between two massive volcanoes - <a href="https://www.earth.com/news/mars-gravity-map-exposes-ancient-structures-and-volcanic-activity/" target="_blank" rel="noreferrer noopener">Olympus Mons</a> to the south and Alba Mons to the northeast. </p>



<p>Scientists from the <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">European Space Agency</a> (ESA) studied the new images to understand better how volcanic and tectonic activity once reshaped the Martian surface.</p>



<h2 class="wp-block-heading" id="h-ancient-structures-reveal-tectonic-past">Ancient structures reveal tectonic past</h2>



<p>The right side of the image reveals a network of long, trench-like structures known as grabens. These geological features formed on Mars when the planet's crust was pulled apart by tectonic stress.</p>



<p>Huge blocks of land cracked, sank, and created deep troughs that are separated by ridges. The grabens formed nearly four billion years ago and stretch about 800 kilometers (500 miles) - roughly the length of Germany.</p>



<p>The crustal tension responsible for the grabens likely came from the shifting of Mars’s surface during periods of intense volcanic activity. </p>



<p>The presence of nearby volcanoes, such as Olympus Mons and Alba Mons, suggests a strong link between volcanic activity and surface deformation in this area.</p>



<h2 class="wp-block-heading" id="h-glaciers-and-lava-shape-younger-plains">Glaciers and lava shape younger plains</h2>



<p>Just below the center of the image is a smooth region that marks the beginning of younger plains. These plains were likely formed by glacial movement and lava flows. </p>



<p>Close to the grabens, evidence points to rock glaciers - combinations of ice and rock - that flowed slowly over time. These glaciers appear to have crept away from the cliffs, leaving behind patterns that resemble waves lapping at a shoreline. </p>



<p>The movement ends in gently sloping piles of debris, known as "debris aprons," that spread away from the cliff bases.</p>



<h2 class="wp-block-heading" id="h-older-features-of-mars">Older features of Mars</h2>



<p>Zoomed-in 3D views highlight the grabens, glacial flow, and areas where lava poured over older features. </p>



<p>One clear example is a half-visible impact crater, about 28 kilometers (17 miles) wide, that is partially buried beneath a smooth lava field. This suggests the crater existed before the volcanic activity that resurfaced the terrain.</p>



<p>In the upper right of the main image, three cone-shaped peaks rise above the plains. These domes are likely volcanic in origin. </p>



<p>What’s fascinating is that the grabens slice through some of these features, indicating that the crust continued to stretch and shift even after the volcanic domes formed.</p>



<h2 class="wp-block-heading" id="h-powerful-geological-changes-on-mars">Powerful geological changes on Mars</h2>



<p>Since launching in 2003, ESA’s Mars Express has been <a href="https://www.earth.com/news/mars-captured-in-true-color-like-youve-never-seen-the-red-planet-before/" target="_blank" rel="noreferrer noopener">photographing Mars in color</a> and 3D with high resolution. For over 20 years, it has offered scientists a window into the Red Planet’s layered history. </p>



<p>Today, the spacecraft continues to reveal how time, lava, and ice worked together to shape the Martian landscape.</p>



<p>The Acheron Fossae image is just one example of how Mars, though quiet today, was once a planet of powerful geological change.</p>



<h2 class="wp-block-heading" id="h-a-window-into-planetary-evolution">A window into planetary evolution</h2>



<p>Scientists continue to investigate areas such as Acheron Fossae in order to learn more about the forces that sculpted not just Mars, but rocky planets in general. </p>



<p>The <a href="https://www.earth.com/news/odyssey-orbiter-captures-unprecedented-images-of-mars/" target="_blank" rel="noreferrer noopener">Red Planet</a> offers a special geological record. Mars does not have plate tectonics and has very little wind or water erosion, unlike Earth, so its surface features have been preserved for billions of years. </p>



<p>These historic landscapes are snapshots of planetary processes locked in time. By examining the cracks, flows, and plains of Mars, scientists can reconstruct how the planet cooled, stretched, and changed. </p>



<p>The fact that there are ancient grabens, glacial landforms, and volcanic plains indicates a complicated and energetic past, even though today the planet is geologically calm. </p>



<p>These findings also assist scientists in constructing improved models of the appearance of other planets in the distant past.</p>



<p>With additional missions in the pipeline, including future sample-return missions and eventual crewed missions, Mars will continue to provide new opportunities to study planetary history, climate evolution, and the <a href="https://www.earth.com/news/mars-curiosity-rover-finds-sulfur-crystals-martian-rock-hints-at-possible-life/" target="_blank" rel="noreferrer noopener">possibility of ancient life</a>.</p>

Split personality of Mars revealed in its striking features

Mars is a planet of dramatic contrasts. Roughly one hemisphere...

<p>Comets streak in from the outer solar system, shed streams of dust, and sometimes trigger brief meteor storms on Earth. For years, astronomers blamed the random tug of the planets for the way these meteoroid streams gradually drift in and out of Earth’s path.</p>



<p>However, a new study led by <a href="https://www.seti.org/" target="_blank" rel="noreferrer noopener">SETI Institute</a> scientists Stuart Pilorz and Peter Jenniskens argues that the real architect is more subtle. The research points to the Sun’s own motion around the solar‑system barycenter, the shared center of mass for all planets and the Sun.</p>



<p>“Contrary to popular conception, everything in the <a href="https://www.earth.com/news/spiral-structure-discovered-at-the-edge-of-our-solar-system-oort-cloud/" target="_blank" rel="noreferrer noopener">solar system</a> does not orbit the Sun,” explained Pilorz. “Rather, the Sun and planets all orbit their common center of mass, known to scientists as the solar system barycenter.”</p>



<p>That off‑center dance gives long‑period comets - and the dust grains they release - a tiny gravitational nudge each time they dive toward the inner solar system. Over centuries, those nudges unravel a needle‑thin meteoroid ribbon into a broad, wandering sheet.</p>



<h2 class="wp-block-heading" id="h-position-and-velocity-of-the-sun">Position and velocity of the Sun</h2>



<p>Most orbital models anchor the <a href="https://www.earth.com/news/see-the-sun-in-exquisite-detail-in-rare-solar-orbiter-video/" target="_blank" rel="noreferrer noopener">Sun</a> at the exact center, a convenient simplification because it holds more than 99 percent of the solar system’s mass. But the new work shows that the simplification hides the critical mechanism that disperses long‑period comet streams.</p>



<p>“Long‑period comets spend most of their lives so far away from the solar system that they feel the tug from the barycenter,” Pilorz said. “But every few hundred years they swoop inside Jupiter’s orbit and come under the Sun’s influence.”</p>



<p>During that brief inner‑system swing, solar heating triggers jets of gas that eject dust grains. The grains initially follow the comet’s path, forming a ribbon so narrow that Earth almost never encounters it. </p>



<p>Yet when each grain nears the Sun again, it experiences a gravitational boost or braking because the Sun has shifted slightly in both position and velocity. This shift is relative to the barycenter since the previous visit.</p>



<p>“That kick is exactly in the same way that we use planetary encounters to speed or slow down spacecraft,” Pilorz stated. If you imagine bouncing a tennis ball off the front or back of a moving train, the analogy fits: the ball’s speed changes only because the train itself is moving.</p>



<h2 class="wp-block-heading" id="h-meteor-showers-and-the-sun-s-wobble">Meteor showers and the Sun's wobble </h2>



<p>Jenniskens first suspected the Sun’s wobble was important in 1995, when he noticed that certain ephemeral meteor showers - sometimes lasting less than an hour - seemed to recur on a 60‑year rhythm. </p>



<p>That period matched the combined gravitational influence of Jupiter’s 12‑year orbit and Saturn’s 30‑year orbit, which together dictate the Sun’s main oscillation around the barycenter.</p>



<p>“We traveled to Spain in an attempt to record one of these showers and saw what was described in the past as ‘stars fall at midnight.' The whole shower lasted only 40 minutes, but there was a bright meteor every minute at the peak," noted Jenniskens.</p>



<p>The observation validated his prediction method: track where Jupiter and <a href="https://www.earth.com/news/massive-energy-imbalance-discovered-on-saturn/" target="_blank" rel="noreferrer noopener">Saturn</a> will push the Sun, then forecast when a dust stream - nudged by that same motion - will intersect Earth.</p>



<h2 class="wp-block-heading" id="h-subtle-jumps-reshape-meteoroid-path">Subtle jumps reshape meteoroid path</h2>



<p>Inside <a href="https://www.earth.com/news/secrets-of-jupiters-magnetosphere-will-help-us-predict-space-weather/" target="_blank" rel="noreferrer noopener">Jupiter</a>’s orbit, a meteoroid abandons the barycenter frame and orbits the Sun directly. When it retreats beyond Jupiter, it switches back to barycentric motion.</p>



<p>“We found that the two jumps in the plane of motion, when the Sun takes control as the comet approaches and then again when it hands control back to the barycenter as the comet heads away, kicked the inclination and node of the orbit by a small amount,” said Pilorz.</p>



<p>Grains at different points in the stream meet the Sun at different barycentric phases, so each accrues a slightly different orbital tweak. </p>



<p>Over centuries the narrow ribbon diffuses, weaving above and below Earth’s path - sometimes delivering a brief meteor outburst, other times leaving the night sky empty.</p>



<h2 class="wp-block-heading" id="h-reframing-the-random-comet-streams">Reframing the random comet streams</h2>



<p>“We’re used to telling ourselves that a comet’s motion changes randomly due to a series of complex perturbations from the planets,” said Pilorz. “That isn’t wrong, but if we recall that the Sun also orbits the barycenter, the explanation becomes much simpler.”</p>



<p>Planetary tugs still matter: between Jupiter and Saturn, their combined <a href="https://www.earth.com/news/mars-gravity-pulls-earth-closer-to-the-sun-warming-our-climate-scientists-say/" target="_blank" rel="noreferrer noopener">gravity</a> exerts a steady torque that slowly precesses a meteoroid stream’s orbit. </p>



<p>Yet the study shows that the dominant driver of the short‑term, seemingly erratic spreading is the Sun’s own wander.</p>



<h2 class="wp-block-heading" id="h-meteor-forecasts-and-lost-comets">Meteor forecasts and lost comets</h2>



<p>Understanding how quickly a meteoroid stream disperses helps astronomers trace the dusty breadcrumb trail. Trails are traced back to a parent comet, even if the comet itself has grown faint or disappeared. </p>



<p>The new framework gives modelers a cleaner way to predict when Earth will next plow through a dense filament - information useful for both sky watchers and satellite operators wary of high‑speed dust impacts.</p>



<p>By recognizing that our star is a fellow traveler around the solar system’s barycenter, astronomers can now see the graceful mechanism behind what once looked like cosmic caprice. </p>



<p>The Sun’s gentle sway sets the rhythm for meteor showers that occasionally turn the night sky into a fleeting storm of falling stars.</p>



<p>The study is published in the journal <a href="https://www.sciencedirect.com/science/article/abs/pii/S001910352500106X?via%3Dihub" target="_blank" rel="noreferrer noopener"><em>Icarus</em></a>.</p>

How the wobbling Sun can help us predict meteor showers

Comets streak in from the outer solar system, shed streams...

<p>Recent research points to protein-rich food choices as powerful drivers of health. Many people are now asking whether a meat-heavy approach to protein is truly the best strategy when it comes to living longer.</p>



<p>The recent findings show that countries with higher levels of animal-based protein see lower mortality rates among children under five, yet plant-based protein is linked with longer lifespans for adults.</p>



<p>The study was conducted out by PhD candidate Caitlin Andrews and her team, led by Dr. Alistair Senior at the <a href="https://www.sydney.edu.au" target="_blank" rel="noreferrer noopener">University of Sydney</a>.</p>



<h2 class="wp-block-heading" id="h-from-plants-to-meat-protein">From plants to meat <strong>protein</strong></h2>



<p>Populations worldwide seem to be trading vegetables for meat. Researchers have observed that animal-based protein consumption has climbed across various regions over the past several decades. More societies are gravitating toward protein-dense foods derived from cattle, poultry, and pigs.</p>



<p>These shifts are not uniform, though. In several corners of the globe, chickpeas, beans, and other legumes are still mainstays, along with certain dairy and egg products. In resource-constrained nations, individuals often rely on whatever is the most affordable form of protein.</p>



<h2 class="wp-block-heading" id="h-meat-protein-lowers-child-death-rates">Meat protein lowers child death rates</h2>



<p>“For the <a href="https://www.who.int/news-room/fact-sheets/detail/child-mortality-under-5-years" target="_blank" rel="noreferrer noopener">under-fives</a>, a food system that supplies large amounts of animal-based proteins and fats lowered rates of infant mortality,” said Andrews.</p>



<p>In places where young children miss out on ample nutrition, extra amounts of animal-based protein can be tied to better early survival rates.&nbsp;</p>



<p>One explanation involves the nutrients found in eggs, dairy, and meat. These foods contain essential amino acids, iron, zinc, and vitamins that help children grow. They also provide energy-dense fat, which supports early development.</p>



<p>Families who live in impoverished settings, however, often struggle to access such staples.</p>



<h2 class="wp-block-heading" id="h-plant-protein-helps-adults-live-longer">Plant protein helps adults live longer</h2>



<p>“For adults, plant-based proteins increased overall life expectancy,” said Andrews.</p>



<p>Higher plant-based protein intake appears to bring key advantages. Diets built around legumes, peas, lentils, and nuts are linked with fewer chronic conditions, including <a href="https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.109.924977" target="_blank" rel="noreferrer noopener">cardiovascular disease</a>.</p>



<p>Adults who rely on beans, lentils, or tofu may also get more dietary fiber. That <a href="https://www.hsph.harvard.edu/nutritionsource/carbohydrates/fiber/" target="_blank" rel="noreferrer noopener">fiber</a> supports normal digestion and can lower the risk of type 2 diabetes. Meanwhile, too much red or processed meat is often linked with harmful effects that might shorten lifespan.</p>



<h2 class="wp-block-heading" id="h-good-fats-early-less-later">Good fats early, less later</h2>



<p>Another interesting aspect involves fat. Research suggests that in infancy and early childhood, certain animal fats might help reduce malnutrition. </p>



<p>Later in life, though, cutting back on high-fat products can aid weight management, possibly easing issues like <a href="https://www.ncbi.nlm.nih.gov/books/NBK572145/" target="_blank" rel="noreferrer noopener">type 2 diabetes</a> and <a href="https://my.clevelandclinic.org/health/diseases/4314-hypertension-high-blood-pressure" target="_blank" rel="noreferrer noopener">hypertension</a>.</p>



<p>Foods loaded with saturated fat may disrupt the balance if combined with processed sugars and a sedentary lifestyle. Such combinations might trigger an inflammatory state and higher vulnerability to illnesses. </p>



<p>This pattern emphasizes how dietary composition can be more important than any single <a href="https://www.earth.com/news/animals-are-suffering-from-declining-plant-quality/" target="_blank" rel="noreferrer noopener">nutrient</a>.</p>



<h2 class="wp-block-heading" id="h-a-higher-cost-for-the-planet">A higher cost for the planet</h2>



<p>“Protein is a crucial part of the human diet, but as eating habits change and developed countries look to decarbonize, where we get our protein from has come under greater scrutiny,” noted the research team.</p>



<p>Meat production draws attention for environmental reasons. Livestock farming typically requires more land and water compared to growing legumes or grains.</p>



<p>Those aiming to reduce <a href="https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions" target="_blank" rel="noreferrer noopener">greenhouse gas emissions</a> often look to pea or chickpea farming as lower-impact methods. This is sparking interest in alternative proteins, such as <a href="https://www.earth.com/news/plant-based-foods-promote-weight-loss-regardless-of-processing/" target="_blank" rel="noreferrer noopener">plant-based</a> meat.</p>



<p>But these shifts need to be carefully approached, given how vital animal-sourced protein appears to be for child development.</p>



<h2 class="wp-block-heading" id="h-shifting-protein-needs">Shifting protein needs</h2>



<p>What each person puts on the plate can differ by budget and culture. For families with small children, variety may be the safest bet. Adults seeking to improve their longevity might gain from swapping out meat for beans, peas, or other plant-based sources.</p>



<p>Some individuals find plant protein more economical, while others view meat as a valued tradition. Experts advise that local resources and medical concerns shape the ideal balance. </p>



<p>The best approach might be a mixed plan, adjusting as people move from childhood into later stages of life.</p>



<h2 class="wp-block-heading" id="h-rethinking-protein-for-global-well-being">Rethinking protein for global well-being </h2>



<p>These results highlight a pattern: keep an eye on total protein intake first, then prioritize more plant-based sources past childhood. </p>



<p>Future innovations may focus on improving vegetarian options for children at risk of malnutrition. Researchers also stress the need for more accessible programs, especially in areas with low food security.</p>



<p>Shifting the global menu can pose challenges. It involves policy support, agricultural reforms, and nutrition education. The end goal is to see infants thrive and older people enjoy extra years, while also safeguarding natural resources.</p>



<p>The study is published in <a href="https://www.nature.com/articles/s41467-025-58475-1" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a>.</p>

Meat protein boosts survival, but plants boost longevity

Recent research points to protein-rich food choices as powerful drivers...

<p>Every day, we face distractions that fight for our attention like vivid billboards. Yet, we often brush them aside without meaning to, as if our minds quietly file them under the “not needed” category.</p>



<p>Recent findings indicate that repeated exposure teaches our <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">brains</a> to downplay flashy elements and rather focus attention on relevant information. The researchers point to this process as a key reason why we can eventually tune out bold visuals.</p>



<p>The study's lead author, Dock Duncan of <a href="https://vu.nl/en" target="_blank" rel="noreferrer noopener">Vrije Universiteit Amsterdam</a>, collaborated with co-author Dr. Norman Forschack from the Wilhelm Wundt Institute of Psychology at <a href="https://www.uni-leipzig.de/en" target="_blank" rel="noreferrer noopener">Leipzig University</a>.</p>



<h2 class="wp-block-heading" id="h-attention-fades-with-repeated-distraction">Attention fades with repeated distraction</h2>



<p>In a set of <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3491357/" target="_blank" rel="noreferrer noopener">EEG studies</a>, 24 volunteers were tasked with picking out a standout shape. The participants were asked to locate a specific object, for example a green circle among green diamonds, while a distracting stimulus - a red diamond - was repeatedly planted in a particular spot in the field of view.</p>



<p>Analysis of brain activity showed that, over time, participants got better at ignoring the attention-grabbing stimulus. Their brains began to suppress information from that position within the very first moments of visual processing. </p>



<p>“We found consistent evidence that <a href="https://www.earth.com/news/brain-mapping-research-mouse-neurons-revolutionary-advance/" target="_blank" rel="noreferrer noopener">learning</a> alters the early responses of the visual system to these stimuli,” said Dr. Forschack.</p>



<p>The distractor seemed less alarming with each appearance, suggesting that our brains swiftly adapt to repeated signals.</p>



<h2 class="wp-block-heading" id="h-distractions-in-the-same-location">Distractions in the same location</h2>



<p>Experts say that it's not just about what the flashy item looks like, but also where it sits. If something overwhelming pops up in one spot again and again, that area gradually becomes a mental gray zone.</p>



<p>“Interestingly, we also observed reduced visual processing for target stimuli when they appeared in the position where the distractor had been frequently shown,” said Dr.  Forschack.</p>



<p>This suggests that even helpful information can slip under the radar if it shows up in a place that our <a href="https://www.earth.com/news/new-brain-pathways-identified-as-being-unique-to-humans/" target="_blank" rel="noreferrer noopener">minds</a> have learned to disregard.</p>



<h2 class="wp-block-heading" id="h-our-brain-filters-out-irrelevant-information">Our brain filters out irrelevant information </h2>



<p>Some <a href="https://pubmed.ncbi.nlm.nih.gov/25631249/" target="_blank" rel="noreferrer noopener">scientists</a> refer to this as a hallmark of <a href="https://www.statlearning.com/" target="_blank" rel="noreferrer noopener">statistical learning</a>, the mind’s built-in knack for noticing patterns that pop up often in daily life. </p>



<p>By homing in on what truly matters, we avoid being swarmed by the same old signs and icons that rarely have new meaning.</p>



<p>Many believe this adaptation is a crucial mental shortcut. It spares us from a flood of distraction, and helps us focus attention on important tasks and signals.</p>



<h2 class="wp-block-heading" id="h-repeated-designs-lose-attention-over-time">Repeated designs lose attention over time</h2>



<p>In traffic, repeated ads and placards might fade into the background, freeing drivers from constant sensory overload. Consistent layouts on highways can help people navigate more smoothly, with less stress.</p>



<p>Still, a new caution sign might get lost if it looks too much like a familiar roadside poster. That same principle applies to web design or app layouts, where a fresh alert might blend too easily with older, repetitive elements.</p>



<h2 class="wp-block-heading" id="h-familiar-distractions-can-hide-alerts">Familiar distractions can hide alerts </h2>



<p>“It is clear that people automatically recognize familiar user interfaces or textbook chapter layouts and find these useful, and that this effect is already reflected in basic visual processing,” noted Duncan.</p>



<p>While this is handy for quick browsing, it can also mean that we miss the latest updates when they appear in a well-worn spot.</p>



<p>Designers might want to vary the look of alerts or shift their placement to counteract these autopilot habits. The goal is to make sure truly important notifications stand out in a crowd of familiar banners.</p>



<h2 class="wp-block-heading" id="h-tuning-out-repeated-visuals">Tuning out repeated visuals</h2>



<p>The mechanism behind this type of <a href="https://www.earth.com/news/how-our-brains-build-mental-maps-of-the-world/" target="_blank" rel="noreferrer noopener">learned</a> filtering is still under active study. Some researchers wonder if it relies on quiet shifts in brain connectivity or if it springs into action only when a bright item appears again.</p>



<p>So far, these experiments highlight how the mind fine-tunes attention and filters out distractions. They also show how repeated exposure can form mental blind spots that help us stay calm in busy surroundings but might also make us ignore fresh warnings.</p>

Our brain stops paying attention to repeated distractions

Every day, we face distractions that fight for our attention...

<p>When country music legend Glen Campbell took the stage during his final tour, his memory was fading fast due to Alzheimer’s disease. </p>



<p>Yet somehow, despite not recognizing his closest loved ones or remembering what day it was, he could still play his guitar and sing every lyric of his greatest hits thanks to the science behind the connection of music and the brain.</p>



<h2 class="wp-block-heading" id="h-the-power-of-music">The power of music </h2>



<p>Rhonda Winegar is a nurse practitioner in neurology and assistant professor at the University of Texas at Arlington. She found Campbell's uncanny ability to be more than just touching - it sparked her scientific curiosity.</p>



<p>“He kept wandering off, and they’d have to push him back on stage,” noted Winegar. “Yet he could still play all those difficult chords and remember the lyrics to his songs.”</p>



<p>This striking example of music’s resilience in the face of neurodegeneration became the foundation for Winegar’s research into the profound <a href="https://www.earth.com/news/music-therapy-key-features-of-healing-music-identified/" target="_blank" rel="noreferrer noopener">therapeutic power</a> of music. </p>



<p>Her findings, recently published with co-author Dustin Hixenbaugh in <a href="https://linkinghub.elsevier.com/retrieve/pii/S1555415525000327" target="_blank" rel="noreferrer noopener"><em>The Journal for Nurse Practitioners</em></a>, reinforce what many have intuitively known for centuries: music isn’t just entertainment - it’s medicine.</p>



<h2 class="wp-block-heading" id="h-chemistry-of-the-musical-experience">Chemistry of the musical experience</h2>



<p>“Music delays neurodegeneration in conditions such as <a href="https://www.earth.com/news/new-blood-test-can-track-the-progression-of-alzheimers/" target="_blank" rel="noreferrer noopener">Alzheimer’s</a>,” Winegar explained. “Sometimes, patients with memory issues get anxious and upset, which can start affecting their speech and ability to communicate. But if they’re able to sing, they can express their feelings, which helps reduce anxiety, stress, and depression.”</p>



<p>While Winegar’s work highlights music’s ability to soothe and strengthen neurological function, a recent imaging study from the Turku PET Center in Finland delves even deeper. The study dives into the molecular chemistry of the musical experience. </p>



<p>Published in the <a href="https://link.springer.com/article/10.1007/s00259-025-07232-z" target="_blank" rel="noreferrer noopener"><em>European Journal of Nuclear Medicine</em></a>, the research has found that listening to favorite music activates the brain’s opioid system, the same reward system that governs pleasure from food, social bonding, and even <a href="https://www.earth.com/news/music-as-a-pain-reliever-the-power-of-your-playlist/" target="_blank" rel="noreferrer noopener">pain relief</a>.</p>



<h2 class="wp-block-heading" id="h-pleasure-pathways-in-the-brain">Pleasure pathways in the brain</h2>



<p>“These results show for the first time directly that listening to music activates the brain’s opioid system,” said Vesa Putkinen from the <a href="https://www.utu.fi/en" target="_blank" rel="noreferrer noopener">University of Turku</a>. </p>



<p>“The release of opioids explains why music can produce such strong feelings of pleasure, even though it is not a primary reward necessary for survival or reproduction, like food or sexual pleasure.”</p>



<p>Using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), the Finnish research team measured the release of natural opioids in the brain as participants listened to music that gave them chills. </p>



<p>The more opioid receptors a person had, the stronger their <a href="https://www.earth.com/news/music-triggers-unique-prediction-zones-in-the-brain/" target="_blank" rel="noreferrer noopener">brain</a> responded to the music - suggesting a biological basis for why some people are deeply moved by a favorite song while others remain unmoved.</p>



<p>“The brain’s opioid system is also involved in pain relief. Based on our findings, the previously observed pain-relieving effects of music may be due to music-induced opioid responses in the brain,” noted Lauri Nummenmaa, a professor at the University of Turku.</p>



<h2 class="wp-block-heading" id="h-music-therapy-heals-the-brain">Music therapy heals the brain</h2>



<p>Back in Texas, Winegar describes the ways in which this pleasurable response to music can be practically applied in medicine and caregiving. Active music therapy - where patients sing or play instruments - can help stroke survivors regain language skills.</p>



<p>Music therapy can also be beneficial for people with <a href="https://www.earth.com/news/dopamine-plays-an-unexpected-role-in-movement-and-parkinsons-disease/" target="_blank" rel="noreferrer noopener">Parkinson’s</a>, as it may improve walking rhythm and motor control. Passive listening also shows benefits, such as reducing heart rate, blood pressure, and seizure activity.</p>



<p>“In neurology, music has been shown to decrease seizure activity by calming abnormal electrical impulses in the brain,” she said. “Research also shows that music can regulate heart rate and blood pressure by reducing over excitation in the nervous system.”</p>



<h2 class="wp-block-heading" id="h-right-song-right-person">Right song, right person</h2>



<p>The power of music therapy isn’t restricted to one genre, either. Winegar’s own research was presented through the lens of country music, which she describes as “a support group in song.” </p>



<p>However, the emotional and physiological effects vary widely depending on personal preference. Whether someone finds peace in heavy metal or motivation in gospel, the brain’s response is most powerful when the music resonates personally.</p>



<p>“We focused on how country music can be used in a clinical setting,” Winegar said. “It often tells the stories of struggle - my wife left me, I’m an alcoholic, my truck won’t start. We framed our presentation around the idea that music can serve as a support group, helping people connect with others facing similar struggles.”</p>



<h2 class="wp-block-heading" id="h-using-music-to-heal-the-brain">Using music to heal the brain</h2>



<p>With neuroscience revealing the biological underpinnings of music’s effects and clinicians harnessing its healing potential, the implications for health care are enormous. </p>



<p>From managing chronic pain and regulating mood to enhancing mobility and preserving memory, music offers an accessible way to heal the brain and treat mental health conditions.</p>



<p>“The most important takeaway from this research is that music has always been there for us. It doesn’t cost anything to turn on the radio, and it can be there for you during rough patches - whether you’re feeling anxious, depressed or in pain. It can motivate you, help you exercise or provide comfort,” said Winegar.</p>



<p>As science continues to explore the symphony between mind and music, it’s becoming increasingly clear that this universal human experience is more than just background noise. It’s a form of therapy written into our biology - a healing harmony available to all.</p>

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

</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>

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.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>

<p>Today’s <strong>Video of the Day</strong> from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.</p>



<p>“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. </p>



<p>The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.</p>



<p>“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;</p>



<p>“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”</p>



<p>The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;</p>



<p>The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?</p>



<p>One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;</p>



<p>While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Santiago, the capital city of Chile. The city is located in the center of the Santiago Metropolitan Region, which has a population of about eight million people.&nbsp;</p>



<p>'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."</p>



<p>"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.</p>
