<p>Inside our bodies, countless decisions play out silently at the cellular level. Some cells divide, some die, and others are forced out when they no longer serve their purpose. </p>



<p>A study from <a href="https://www.kcl.ac.uk" target="_blank" rel="noreferrer noopener">King’s College London</a> and the <a href="https://www.crick.ac.uk" target="_blank" rel="noreferrer noopener">Francis Crick Institute</a> reveals that epithelial cells use electricity to spot weak neighbors and remove them. This breakthrough offers fresh insight into how diseases like cancer and stroke arise when energy balance within cells is disturbed.</p>



<h2 class="wp-block-heading" id="h-cells-renew-constantly">Cells renew constantly</h2>



<p>Epithelial <a href="https://www.earth.com/news/hemifusome-newly-discovered-organelle-inside-human-cells-with-immense-potential/">cells</a> form the barrier that lines organs, renewing rapidly to stay protective. Their balance depends on extrusion, the process of ejecting damaged or excess cells. This keeps tissues tightly packed and efficient. </p>



<p>If extrusion falters, cell numbers become chaotic, creating openings for disease. Without this constant regulation, unhealthy cells may linger, disrupt organ integrity, and interfere with critical signaling pathways. </p>



<p>Over time, these disturbances can weaken the protective barrier, encourage unchecked growth, and increase vulnerability to conditions such as cancer, chronic inflammation, or infections that compromise overall tissue health and resilience.</p>



<h2 class="wp-block-heading" id="h-electricity-targets-weak-cells">Electricity targets weak cells</h2>



<p>Earlier work showed that overcrowding forces some <a href="https://www.earth.com/news/how-did-the-first-cells-life-form-on-earth-scientists-think-they-finally-figured-it-out/">cells</a> to be squeezed out mechanically. The latest discovery goes further. It shows that extrusion is not random but targets energy-poor cells. Crowding pushes sodium into cells through specialized ion channels, altering their electrical signals. </p>



<p>Healthy cells restore balance, but weak ones cannot, triggering shrinkage and eventual extrusion. This reveals a precise surveillance system where tissues actively monitor cellular energy, ensuring only the strongest cells remain. </p>



<p>Such control preserves organ stability, while defects in this mechanism may promote disease progression and unchecked cellular growth.</p>



<h2 class="wp-block-heading" id="h-cells-sense-crowding-with-electricity">Cells sense crowding with electricity</h2>



<p>The researchers noticed a striking prelude to extrusion: cells briefly shrank before being expelled. This stage, termed homeostatic early shrinkage, reflects water leaving the cell. </p>



<p>Roughly 70 percent of extruding cells undergo this <a href="https://www.earth.com/news/cells-vomit-waste-to-speed-up-healing-in-our-body/">shrinkage</a>. It is not caused by contractile forces but by ion channels regulating water movement. Key players include the potassium channels Kv1.1 and Kv1.2, and the chloride channel SWELL1.</p>



<p>The study revealed that an epithelial sodium channel, ENaC, senses crowding. It acts as a tension detector, letting sodium rush in when cells press against one another.</p>



<p>If a cell has enough ATP, it pumps sodium back out and stabilizes. If not, depolarization occurs, potassium and chloride exit, water follows, and the cell shrinks, crossing the threshold that triggers extrusion.</p>



<h2 class="wp-block-heading" id="h-low-energy-as-a-trigger">Low energy as a trigger</h2>



<p>Time-lapse experiments revealed that cells destined for extrusion show falling ATP levels before they depolarize and shrink. When ATP levels were artificially lowered, extrusion increased. </p>



<p>This shows energy deficiency directly selects <a href="https://www.earth.com/news/how-space-changes-our-cells-insights-from-the-iss/">cells</a> for removal. In essence, epithelial tissue runs a built-in fitness test: cells unable to maintain their electrical balance are expelled.</p>



<p>"We see this sodium channel acting as a sensor, exposing cells with the least amount of energy and targeting those cells for death," noted study lead author Dr. Saranne Mitchell. </p>



<p>"This mechanism gives epithelia a constant surveillance system to rapidly detect weak cells and remove them. It's like an electrical quality-control check, keeping tissues robust and functional."</p>



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



<p>The study highlights how epithelial tissues are not passive layers but dynamic communities constantly testing their members. By identifying weaker cells early, they can preserve strength and protect organ function.</p>



<p>"By revealing that cells with low energy are targeted for extrusion, our work also adds a new layer into how metabolism can impact many diseases," said Professor Jody Rosenblatt.</p>



<p>"This new insight could suggest how overconsumption, through eating more and consuming more calories, might override this 'low energy trigger' for extrusion and prevent the elimination of defective cells, allowing them to accumulate into cancers." </p>



<p>"It might also reveal how energy deprivation following a stroke, caused by impacted blood supply, could lead to excess extrusion and organ damage."</p>



<h2 class="wp-block-heading" id="h-cells-use-electricity-effectively">Cells use electricity effectively</h2>



<p>This model highlights energy sufficiency as a deciding factor in cell survival. Much like how mitochondria regulate apoptosis, epithelial extrusion uses energy balance as a checkpoint. </p>



<p>The findings also connect to conditions like cystic fibrosis and cancer, where ion channel malfunctions are common. By linking ion flow, energy, and crowding, this study reframes how tissues maintain integrity.</p>



<p>The discovery paints epithelia as more than static barriers. They are dynamic, electrically sensitive tissues constantly probing their members for weakness. </p>



<p>Cells that cannot meet the energy demands are removed for the greater good of the tissue. Even the faintest electrical flicker within these cellular communities can tip the balance between health and disease.</p>

<p>If you were to rewind the clock to the 1980s and tune your ear to the deep-sea waters off the coast of New Zealand, a peculiar sound might have caught your attention. </p>



<p>This sound, reminiscent of a "quack," echoed through the South Fiji Basin's underwater soundscape in July 1982, presenting a unique mystery for researchers investigating marine acoustics at the time.</p>



<p>This strange, quack-like sound quickly became a topic of widespread interest, and its continuous repetition earned it the nickname "Bio-Duck."</p>



<p>Initially recorded during an experiment designed to characterize the marine audio environment of the region, the sound's repetitive and patterned nature left researchers astonished and intrigued at the possibility that it was biological in origin.</p>



<h2 class="wp-block-heading" id="h-the-source-of-the-quack-still-unknown">The source of the quack still unknown</h2>



<p>One of the pivotal contributors to this research was Ross Chapman who, at the time, was associated with the <a href="https://www.uvic.ca/" target="_blank" rel="noreferrer noopener">University of Victoria</a>. He reflects about how the sound generated heated discussions among scientists who were perplexed about its source.</p>



<p>"The sound was so repeatable, we couldn't believe at first that it was biological. But in talking to other colleagues in Australia about the data, we discovered that a similar sound was heard quite often in other regions around New Zealand and Australia."</p>



<p>The mysterious <a href="https://www.earth.com/news/baleen-whales-cannot-escape-human-noise/" target="_blank" rel="noreferrer noopener">underwater communications</a> became a major point of discussion at the 187th Meeting of the Acoustical Society of America in November, 2024, where Chapman and his team presented their findings. They have yet to identify the makers of these enigmatic sounds.</p>



<h2 class="wp-block-heading" id="h-unchartered-territory-of-ocean-noise-exploration">Unchartered territory of ocean noise exploration</h2>



<p>Chapman’s journey into deciphering the mystery began in 1986 with the analysis of the data from the experiment. </p>



<p>"We discovered that the data contained a gold mine of new information about many kinds of sound in the ocean, including sounds from <a href="https://www.earth.com/news/marine-mammals-in-the-us-are-highly-vulnerable-to-climate-change/" target="_blank" rel="noreferrer noopener">marine mammals</a>," he recalled.  </p>



<p>The field of marine acoustics was in its fledgling stages in the '80s, and every day was an opportunity for a new discovery. </p>



<p>Despite the thrill and excitement, the source of the Bio-Duck sounds remained an enigma, with some theories suggesting that the sounds could be originating from <a href="https://www.earth.com/news/whales-may-have-ultrasonic-hearing-as-a-form-of-defense/" target="_blank" rel="noreferrer noopener">Antarctic minke whales</a>.</p>



<h2 class="wp-block-heading" id="h-engaging-in-a-deep-sea-dialogue">Engaging in a deep-sea dialogue</h2>



<p>Chapman, however, had a different hypothesis. He believed these sounds were something more than just random noises - they could be a conversation. </p>



<p>This hypothesis was supported by the pattern of the sounds recorded by an acoustic antenna, an array of hydrophones towed behind a ship. </p>



<p>The acoustic array's unique design allowed the researchers to identify the direction the sounds were originating from and revealed that they came from different directions all around the ship.</p>



<p>"The most amazing thing was that when one speaker was talking, the others were quiet, as though they were listening. Then the first speaker would stop talking and listen to responses from others," Chapman noted.</p>



<p>This observation hinted at an organized communication pattern among the unseen marine speakers. He likened this to a conversation where one individual speaks while the others wait to respond.</p>



<h2 class="wp-block-heading" id="h-a-story-unfolds-in-the-deep-sea">A story unfolds in the deep sea</h2>



<p>"Maybe they were talking about dinner, maybe it was parents talking to children, or maybe they were simply commenting on that crazy ship that kept going back and forth towing that long string behind it," said Chapman.</p>



<p>While the mystery of the Bio-Duck is yet to be conclusively solved, the intriguing possibility of a deep-sea dialogue continues to fascinate us. </p>



<p>It offers a reminder that the <a href="https://www.earth.com/news/monitoring-ocean-life-through-underwater-soundscapes/" target="_blank" rel="noreferrer noopener">underwater</a> universe is rich with life and communication, and humbles us with the realization that there is so much more left for us to understand about the world beneath the waves.</p>



<h2 class="wp-block-heading" id="h-the-legacy-of-the-bio-duck-mystery">The legacy of the Bio-Duck mystery</h2>



<p>The quack-like sounds of the Bio-Duck are not just a relic of past research; they’ve become a cornerstone for understanding the complexity of deep-sea ecosystems. </p>



<p>These sounds have inspired decades of study into marine <a href="https://www.earth.com/news/language-like-patterns-decoded-in-sperm-whale-communication/" target="_blank" rel="noreferrer noopener">animal communication</a>, particularly among whales and other cetaceans. </p>



<p>Today, advancements in acoustic technology allow scientists to revisit these historical recordings with modern tools, uncovering new layers of information that were previously inaccessible.</p>



<p>In recent years, the Bio-Duck has been referenced in studies seeking to map marine animal behaviors and migration patterns. </p>



<p>These efforts emphasize the importance of long-term data collection, proving that even recordings from the 1980s can yield fresh insights when paired with today’s computational power.</p>



<p>The continued analysis of sounds like the Bio-Duck serves as a reminder of the mysteries still hidden in the deep sea. </p>



<p>They highlight the need for sustainable marine exploration to protect these habitats and preserve the uncharted conversations of the underwater world.</p>

Unknown origin: 'Quack-like' sounds heard in the deep ocean remain a mystery

If you were to rewind the clock to the 1980s...

<p>There is a fruit called the 'squirting cucumber' that fires its seeds like mini ballistic missiles. But how does it do this? Researchers seem to have solved this mystery -- a question that has baffled scientists for hundreds of years.</p>



<p>The results of a recent study, based on a myriad of experiments, high-speed videography, image scrutiny, and advanced mathematical modeling, are published in the journal <em>Proceedings of the National Academy of Sciences</em> (PNAS).</p>



<h2 class="wp-block-heading" id="h-understanding-the-squirting-cucumber">Understanding the squirting cucumber</h2>



<p>The squirting cucumber, or <em>Ecballium elaterium</em>, derives its name from its unique method of <a href="https://www.earth.com/news/plant-seeds-go-dormant-to-avoid-harsh-conditions/" target="_blank" rel="noreferrer noopener">seed</a> dispersal.</p>



<p>As the fruit ripens, it transitions into a seed-launching machine, that can shoot out seeds enveloped in a jet of mucus-like fluid.</p>



<p>In a minuscule span of just 30 milliseconds, the seeds are propelled at speeds of around 20 meters per second or 44 miles per hour, enabling them to land a considerable distance away (approximately 10 meters or 33 feet). </p>



<p>This is equal to around 250 times the length of the fruit itself .</p>



<h2 class="wp-block-heading" id="h-decoding-seed-dispersal">Decoding seed dispersal</h2>



<p>Despite the fruit's intriguing <a href="https://www.earth.com/news/birds-increase-forest-recovery-by-dispersing-seeds/" target="_blank" rel="noreferrer noopener">seed dispersal</a> method, the mechanism behind it -- as well as its impact on the plant's reproduction -- remained elusive until recently.</p>



<p>Scientists from the <a href="https://www.ox.ac.uk" target="_blank" rel="noreferrer noopener">University of Oxford</a> and the <a href="https://www.manchester.ac.uk" target="_blank" rel="noreferrer noopener">University of Manchester</a> ran a battery of tests on <em>Ecballium</em> specimens grown at the University of Oxford Botanic Garden.</p>



<p>These experiments included capturing the seed dispersal in motion using a high-speed camera, conducting indentation tests, measuring the volume of the fruit and stem before and after dispersal, and observing the fruit's changes through time-lapse photography. </p>



<p>Armed with this data, the team devised mathematical models to describe and understand the internal and external mechanics at play.</p>



<h2 class="wp-block-heading" id="h-fluid-distribution-in-squirting-cucumber">Fluid distribution in squirting cucumber</h2>



<p>The team's rigorous approach resulted in the identification of key features of the plant's <a href="https://www.earth.com/news/insects-play-a-much-bigger-role-in-seed-dispersal-than-we-thought/" target="_blank" rel="noreferrer noopener">seed dispersal strategy</a>. </p>



<p>These involve a highly pressurized system, fluid redistribution, rapid recoil, and variable launch - that together form a sophisticated launch system.</p>



<p>The fluid redistribution from the fruit back into the stem, a feature thought to be unique to the squirting cucumber, was among the most significant findings.</p>



<div class="wp-block-sendtonews-playerselector">[sendtonews key="4NlCX5nNI6-4062310-12187" type="single"]</div>



<h2 class="wp-block-heading" id="h-fine-tuning-for-successful-seed-dispersal">Fine-tuning for successful  seed dispersal</h2>



<p>The team's mathematical model helped them explore the effects of altering different parameters, and revealed that the squirting cucumber's seed projection method has been naturally fine-tuned for optimal dispersal and propagation.</p>



<p>For instance, making the stem thicker and stiffer led to a narrower <a href="https://www.earth.com/news/woodlice-prove-crucial-players-plant-seed-dispersal/" target="_blank" rel="noreferrer noopener">dispersal area</a> and, therefore, a lower survival rate.</p>



<p>On the other hand, reducing the fluid transferred from the fruit to the stem caused the seeds to be ejected at accelerated speeds but with a nearly vertical launch angle, again resulting in reduced dispersal and survival rates.</p>



<h2 class="wp-block-heading" id="h-mechanisms-of-a-unique-plant">Mechanisms of a unique plant</h2>



<p>"For centuries people have asked how and why this extraordinary plant sends its seeds into the world in such a violent way," said Dr. Chris Thorogood, Deputy Director and Head of Science at the <a href="https://obga.ox.ac.uk/" target="_blank" rel="noreferrer noopener">Oxford Botanic Garden</a>.</p>



<p>"Now, as a team of biologists and mathematicians, we’ve finally begun to unravel this great botanical enigma." </p>



<p>Dr. Derek Moulton, professor of Applied Mathematics at the Oxford <a href="https://www.maths.ox.ac.uk" target="_blank" rel="noreferrer noopener">Mathematical Institute</a>, also participated in the research.</p>



<p>"The first time we inspected this plant in the Botanic Garden, the <a href="https://www.earth.com/news/one-third-of-europes-plants-at-risk-due-to-decline-in-seed-dispersers/" target="_blank" rel="noreferrer noopener">seed</a> launch was so fast that we weren’t sure that it had actually happened. It was very exciting to dig in and uncover the mechanism of this unique plant," Dr. Moulton explained.</p>



<h2 class="wp-block-heading" id="h-beyond-seed-dispersal">Beyond seed dispersal</h2>



<p>According to Dr. Finn Box, a Royal Society University Research Fellow at the University of Manchester, this study has implications beyond botany.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/11/squirting-cucumber_Ecballium-elaterium_squirting-seeds_UOxford_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/11/squirting-cucumber_Ecballium-elaterium_squirting-seeds_UOxford_1s.webp" alt="A still showing the jet ejected from a squirting cucumber, which carries its seeds distances of up to 10m away from the mother plant.

<p>"This research offers potential applications in bio-inspired engineering and material science, particularly on-demand drug delivery systems, for instance microcapsules that eject nanoparticles where precise control of rapid, directional release is crucial," said Dr. Box.</p>



<h2 class="wp-block-heading" id="h-the-squirting-cucumber-a-part-of-history">The squirting cucumber: A part of history</h2>



<p><em>Ecballium elaterium</em>, a member of the Cucurbitaceae family, which also includes melon, pumpkin, squash, and courgette, is native to the Mediterranean region where it is commonly regarded as a weed due to its effective seed-dispersal strategy.</p>



<p>This plant caught the attention of ancient Greeks and Romans alike, with naturalist Pliny the Elder describing its powerful <a href="https://www.earth.com/news/fossil-reveals-how-plants-use-winged-seeds-to-expand-their-habitats/" target="_blank" rel="noreferrer noopener">seed launch</a> centuries ago.</p>



<h2 class="wp-block-heading" id="h-conservation-and-future-research">Conservation and future research</h2>



<p>Given the squirting cucumber's extensive use as a model for understanding complex biological phenomena, conserving its natural habitats becomes imperative. This plant holds significant scientific and ecological value.</p>



<p>Future research could investigate the genetic underpinnings of its unique <a href="https://www.earth.com/news/insects-play-a-much-bigger-role-in-seed-dispersal-than-we-thought/" target="_blank" rel="noreferrer noopener">dispersal system</a>, linking it to other species within the Cucurbitaceae family to unravel shared evolutionary traits.</p>



<p>Additionally, exploring the potential for cross-disciplinary applications, from environmental management to biomimicry in engineering, could broaden our perspective on how such ecological marvels can benefit human society while preserving biodiversity.</p>



<p>The study is published in the journal <em><a href="https://www.pnas.org/doi/10.1073/pnas.2410420121" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.</em></p>

How the 'squirting cucumber' squirts and the trigger that makes it happen

There is a fruit called the 'squirting cucumber' that fires...

<p>Filter feeders are widespread across the animal kingdom, from krill and coral to baleen whales and basking sharks.&nbsp;</p>



<p>Now, researchers at <a href="https://www.mit.edu/" target="_blank" rel="noreferrer noopener">MIT</a> have uncovered a unique filter-feeding mechanism in mobula <a href="https://www.earth.com/news/ancient-rays-were-more-diverse-than-previously-thought/" target="_blank" rel="noreferrer noopener">rays</a> - a group that includes manta and devil rays - that could inspire breakthroughs in industrial water filtration.</p>



<p>The study reveals how the mobula ray’s adaptations balance feeding efficiency with breathing. The findings offer insights into optimizing industrial cross-flow filters, crucial in water treatment and other industries.</p>



<h2 class="wp-block-heading" id="h-the-manta-ray-s-ingenious-filter-design">The manta ray’s ingenious filter design</h2>



<p>Mobula rays feed by swimming open-mouthed through <a href="https://www.earth.com/news/plankton-help-predict-ocean-biodiversity-losses/" target="_blank" rel="noreferrer noopener">plankton</a>-rich waters, directing water into their mouths and out through their gills. Parallel, comb-like plates line the floor of their mouths, directing water flow while filtering out plankton particles.</p>



<p>The MIT researchers found that these plates are specifically sized to ensure that plankton particles bounce across the plates into the ray’s cavity rather than escaping through its gills. Simultaneously, the outflowing water allows the ray to breathe by oxygenating its gills.</p>



<p>“We show that the mobula ray has evolved the geometry of these plates to be the perfect size to balance feeding and breathing,” said senior author Anette “Peko” Hosoi, a professor of mechanical engineering at MIT.</p>



<h2 class="wp-block-heading" id="h-learning-from-nature-a-new-approach-to-water-filters">Learning from nature: A new approach to water filters</h2>



<p>Inspired by the mobula ray, the researchers designed a simple water filter that mimics the ray’s feeding features. They tested the filter with 3D-printed plates modeled after the ray’s structures and found it could provide a blueprint for improving industrial cross-flow filters.</p>



<p>Cross-flow filters are used in water treatment plants and other industries to separate particles from fluids. These filters work by allowing fluid to flow across a permeable membrane, with clean fluid passing through while particles are carried away into waste reservoirs.</p>



<p>“We want to expand the design space of traditional crossflow <a href="https://www.earth.com/news/new-filtration-system-removes-forever-chemicals-from-water/" target="_blank" rel="noreferrer noopener">filtration</a> with new knowledge from the manta ray,” explained lead author Xinyu Mao, an MIT postdoc.</p>



<p>By examining the ray’s filtration mechanism, the team identified new parameters for optimizing filter performance, particularly regarding the trade-off between permeability and selectivity.</p>



<h2 class="wp-block-heading" id="h-manta-ray-inspiration-for-water-filters">Manta ray inspiration for water filters</h2>



<p>Industrial filters often face a balancing act: filters with larger pores are highly permeable, allowing fluid to flow through easily but letting small particles escape. Filters with smaller pores, on the other hand, are more selective but require more energy to push fluid through.</p>



<p>The mobula ray’s feeding system offers a natural solution to this dilemma. The ray allows water to flow freely enough to breathe while retaining the plankton particles it feeds on.</p>



<p>“We asked ourselves, how do we do better with this trade-off between permeability and selectivity?” Hosoi said.</p>



<p>By studying the ray’s adaptations, the researchers discovered that vortices - tiny swirling flows of water - play a critical role in its feeding efficiency.</p>



<h2 class="wp-block-heading" id="h-the-key-to-efficient-filtering">The key to efficient filtering</h2>



<p>The team’s experiments showed that when water flows through the ray-inspired filter, it creates small vortices at the grooves of the plates. These vortices trap particles while allowing water to flow through unimpeded.</p>



<p>“This vortex is not blocking water, but it is blocking particles,” Hosoi explained. “At higher flow rates, particles try to get through the filter but are blocked by this vortex and are shot down the channel instead.”</p>



<p>The vortices even capture particles smaller than the spacing between the plates, forcing them to bounce across the plates into the ray’s cavity. This mechanism prevents particles from escaping while maintaining high water flow, a feature industrial filters could replicate.</p>



<h2 class="wp-block-heading" id="h-broader-implications-of-the-research">Broader implications of the research</h2>



<p>Using the mobula ray as a model, the researchers developed guidelines for designing cross-flow filters. Their blueprint specifies how factors like pore size, spacing, and flow rate can be adjusted to create vortices for optimal filtration.</p>



<p>“You want to design a filter such that you’re in the regime where you generate vortices,” Hosoi said. “Our guidelines tell you: If you want your plant to pump at a certain rate, then your filter has to have a particular pore diameter and spacing to generate vortices that will filter out particles of this size.”</p>



<p>The findings are particularly relevant to industries like water treatment, where filters must balance efficiency and sustainability.</p>



<h2 class="wp-block-heading" id="h-bridging-nature-and-technology">Bridging nature and technology</h2>



<p>During the COVID-19 pandemic, the team initially focused on designing <a href="https://www.earth.com/news/covid-masks-may-expose-users-to-harmful-chemicals/" target="_blank" rel="noreferrer noopener">face masks</a> capable of filtering viruses. This work eventually shifted to studying natural filtration systems, leading them to the mobula ray.</p>



<p>The ray’s evolved mechanism provides a clear example of how nature can solve engineering challenges. By mimicking this system, industries can create more efficient filters that require less energy while maintaining high selectivity.</p>



<p>“The mobula ray is giving us a really nice rule of thumb for rational design,” Hosoi noted.</p>



<p>The study highlights the potential of biomimicry, where insights from the natural world inspire innovative technological solutions. With the mobula ray as a guide, engineers can refine filtration systems to meet modern demands for cleaner, more sustainable processes.</p>



<p>This research not only advances our understanding of filter-feeding animals but also paves the way for practical applications in technology and industry, demonstrating the profound value of learning from nature.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1073/pnas.2410018121" target="_blank" rel="noreferrer noopener"><em>Proceedings of the National Academy of Sciences</em></a>.</p>

<p>By producing a much-improved assembly of the <em>Amborella</em> genome and its sex chromosomes, the researchers have gained valuable insights into <a href="https://www.earth.com/news/fibonacci-spirals-an-unexpected-twist-in-plant-evolution/" target="_blank" rel="noreferrer noopener">plant evolution</a> and reproduction.</p>



<h2 class="wp-block-heading" id="h-evolution-of-the-amborella-genome">Evolution of the <em>Amborella</em> genome</h2>



<p><em>Amborella trichopoda</em> is the sole surviving member of a lineage that branched off early from all other flowering plants. Its genome provides essential information about the genetic foundations of <a href="https://www.earth.com/news/how-plant-diversity-can-help-combat-climate-change/" target="_blank" rel="noreferrer noopener">plant diversity</a>.</p>



<p>Eleven years ago, an international team of researchers co-led by Jim Leebens-Mack, a professor of plant biology at the University of Georgia, completed the first <em>Amborella</em> genome. The results, published in <a href="https://www.science.org/doi/10.1126/science.1241089?adobe_mc=MCMID%3D90780648708216300104417575982572668868%7CMCORGID%3D242B6472541199F70A4C98A6%2540AdobeOrg%7CTS%3D1732616953"><em>Science</em></a> in 2013, have been cited over 575 times.</p>



<p>“The evolutionary lineage leading to <em>Amborella</em> diverged from all other flowering plant lineages approximately 150 million years ago, so our draft genome published in 2013 has been a foundation for comparative analyses of genes tracing back to the origin of <a href="https://www.earth.com/news/tree-of-life-created-for-flowering-plants-using-400-million-specimens/" target="_blank" rel="noreferrer noopener">flowering plants</a> and earlier,” Leebens-Mack said.</p>



<h2 class="wp-block-heading" id="h-new-insights-into-the-evolution-of-flowers">New insights into the evolution of flowers</h2>



<p>The new insights from the improved genome assembly are particularly exciting for HudsonAlpha Faculty Investigator Alex Harkess, who was a PhD student in Leebens-Mack's lab during the original <em>Amborella</em> genome project.&nbsp;</p>



<p>Now leading his own lab at HudsonAlpha, Harkess and his mentee, senior scientist Sarah Carey, collaborated with Leebens-Mack and HudsonAlphafFaculty investigators Jeremy Schmutz and Jane Grimwood, on the new genome analyses.</p>



<p>“Working on the original <em>Amborella</em> genome in Jim's lab was transformative because it allowed me as a first-year PhD student to be on the very edge of newly developing technologies and software that was coming out to help handle all of this massive genomic data we were creating,” Harkess reflected.&nbsp;</p>



<p>“This <a href="https://www.earth.com/news/how-does-genome-size-impact-evolutionary-success/">genome</a> reveals so much about the evolution of flowers, but also about the evolution of my own research career and the way I, and now my entire laboratory, view reproduction through the lens of diversity.”</p>



<p>Carey, who was a postdoctoral fellow in the Harkess lab when the new genome assembly was completed, led much of the genome analysis, including the study of the <em>Amborella</em> sex chromosomes.</p>



<h2 class="wp-block-heading" id="h-advanced-technology-and-plant-reproduction">Advanced technology and plant reproduction </h2>



<p>Thanks to advanced sequencing and assembly technology, as well as emerging computational tools, Carey and the team at the HudsonAlpha Genome Sequencing Center were able to assemble a significantly improved <em>Amborella</em> genome.&nbsp;</p>



<p>The new, highly contiguous genome reference made it easier to search for the <em>Amborella</em> <a href="https://www.earth.com/news/how-do-animals-balance-their-sex-chromosomes/" target="_blank" rel="noreferrer noopener">sex chromosomes</a>, which are Z and W chromosomes, unlike the familiar human X and Y chromosomes.</p>



<p>“The first <em>Amborella</em> genome was a mixture of short segments of DNA from different sequencing types and technologies,” Carey explained.&nbsp;</p>



<p>“Advancements in long-read sequencing and access to other pieces of information, like Hi-C data, allowed us to assemble larger pieces that made it easier to search for the ZW chromosomes than if it were in lots of smaller pieces.”</p>



<p>In addition to the improved sequencing tools, the team stayed at the forefront of new computational methods.&nbsp;</p>



<p>They developed a pipeline called cytogenetics-by-sequencing to more easily and cost-effectively identify and characterize sex chromosomes in plants, successfully applying it to nearly 30 dioecious plant and animal species.</p>



<h2 class="wp-block-heading" id="h-the-mechanisms-of-sex-determination">The mechanisms of sex determination</h2>



<p>Through their analysis of the <em>Amborella</em> sex chromosomes, the researchers discovered intriguing aspects of the plant's sex-determination system.&nbsp;</p>



<p>Notably, the Z and W chromosomes are relatively young, having emerged more than 100 million years after <em>Amborella</em> diverged from other flowering plant lineages.</p>



<p>In many sex-determination systems, such as the human Y chromosome, the sex chromosomes stop exchanging genetic material with their partner chromosome - a phenomenon known as recombination suppression.&nbsp;</p>



<p>This allows the two sex chromosomes to diverge over time due to different rearrangements, deletions, and insertions.</p>



<h2 class="wp-block-heading" id="h-genes-associated-with-flower-evolution">Genes associated with flower evolution</h2>



<p>While the team found evidence of suppressed recombination in <em>Amborella</em>, the Z and W chromosomes appear very similar, making their assembly more challenging.</p>



<p>“The cytogenetics-by-sequencing pipeline helped us to identify a difficult border on the <em>Amborella</em> sex chromosomes: where they no longer recombine,” Carey noted.&nbsp;</p>



<p>“This is an important task because within this region of non-recombination are expected to be the carpel and stamen sterility genes associated with the evolution of separate female and male plants.”</p>



<p>By carefully analyzing the sex chromosomes, Carey and the team identified two genes hypothesized to be responsible for sex determination in <em>Amborella</em>.</p>



<h2 class="wp-block-heading" id="h-implications-for-agriculture-and-plant-breeding">Implications for agriculture and plant breeding</h2>



<p>“The big picture takeaway from this study is that we're learning another exception for how you can maintain separate sexes in plants,” Harkess said.&nbsp;</p>



<p>“That gives us another tool in our toolkit for engineering new ways to do plant breeding, creating separate sexes, preventing plants from self-pollinating, and enforcing outcrossing in a way that is controllable and predictable.”</p>



<p>The new <em>Amborella</em> genome project was part of the <a href="https://jgi.doe.gov/csp-2018-leebens-mack-open-green-genomes-initiative/" target="_blank" rel="noreferrer noopener">Open Green Genomes Initiative</a>, a Department of Energy Joint Genome Institute Community Science Program.</p>



<p>“The Open Green Genomes initiative is filling phylogenetic gaps in the availability of reference-quality genomes for land plants,” said Leebens-Mack, lead principal investigator for the initiative.&nbsp;</p>



<p>“Our haplotype-resolved chromosomal assembly of the <em>Amborella</em> genome has enabled us to better understand aspects of the ancestral angiosperm genome and the derived characteristics of <em>Amborella</em>'s sex chromosomes."</p>



<p>This research not only advances our understanding of plant reproduction but also offers practical applications for agriculture and plant breeding.&nbsp;</p>



<p>By unraveling the genetic mechanisms behind sex determination in plants, scientists can develop new strategies to improve crop yields, enhance biodiversity, and ensure <a href="https://www.earth.com/news/vaccinating-plants-could-boost-global-food-security/" target="_blank" rel="noreferrer noopener">food security</a>.</p>

A new window into the early evolution of flowering plants

Plant reproduction is fundamental to our food systems and ecological...

<p>Every living being has a unique way of dealing with adversity. Amid the length and breadth of fauna, bats have always stunned us with their exceptional navigational skills, largely attributable to their acute sense of hearing. But what happens when these creatures lose their most critical sense - can they still find their way in the dark?</p>



<p>New research from The Johns Hopkins University breaks fresh ground in this area, revealing that bats, in fact, do switch to a backup plan when their hearing takes a hit. </p>



<p>This extraordinary discovery broadens our understanding of the adaptability of the brain in the face of sensory deprivation. But, is this ability exclusive to bats, or could it be lurking in other animals or even us humans?</p>



<h2 class="wp-block-heading" id="h-how-bats-adapt-to-hearing-loss">How bats adapt to hearing loss</h2>



<p>Picture a scenario where <a href="https://www.earth.com/news/bats-have-acoustic-mental-maps-to-navigate-total-darkness/" target="_blank" rel="noreferrer noopener">echolocating bats</a>, who rely heavily on hearing, face a sudden shutdown of a key auditory region in their brain. </p>



<p>One would anticipate some serious navigational glitches. Not really, as the research team at <a href="https://www.jhu.edu" target="_blank" rel="noreferrer noopener">Johns Hopkins</a> found out.</p>



<p>We've seen animals and humans alike adapt to sensory deprivation. Amid the clamor of a crowded bar, you might lean closer to a friend to hear them better. Your pet might cock its head to catch a faint rustling. </p>



<p>The question here is - how does an echolocating bat, for whom hearing is a lifeline, cope with such a loss?</p>



<h2 class="wp-block-heading" id="h-bats-adapt-to-compromised-hearing">Bats adapt to compromised hearing </h2>



<p>To explore this, the researchers designed a unique experiment. The bats were trained to fly down a corridor and through a window to fetch a treat from a platform. </p>



<p>Next, the same task was repeated, but with a twist. A critical <a href="https://www.earth.com/news/fruit-bats-can-remember-the-past-and-plan-for-the-future/" target="_blank" rel="noreferrer noopener">auditory pathway</a> in the bats' midbrain was temporarily blocked, an effect equivalent to most auditory signals from reaching the brain's deep regions.</p>



<p>The results are nothing short of surprising. Despite their compromised hearing, the bats were able to navigate the course quite impressively, right from the first attempt. </p>



<p>No, they weren't as sleek as before and did bump into things. But what mattered was that every bat adapted instantly.</p>



<div class="wp-block-sendtonews-playerselector">[sendtonews key="vjQug3TsGx-4062597-12187" type="single"]</div>



<h2 class="wp-block-heading" id="h-changes-in-flight-and-vocalizations">Changes in flight and vocalizations</h2>



<p>“Bats have this amazing flexible adaptive behavior that they can employ anytime,” said study senior author&nbsp;Cynthia F. Moss, a Johns Hopkins neuroscientist who studies bats.</p>



<p>The bats chose to fly lower, aligned themselves along walls, and made more frequent and lengthier calls. This amplification of echo signals compensated for their <a href="https://www.earth.com/news/how-bats-navigate-noisy-world/" target="_blank" rel="noreferrer noopener">navigation</a>.</p>



<p>“Echolocation acts like strobes, so they were basically taking more snapshots to help them get the missing information,” said study co-author Clarice A. Diebold, a former Johns Hopkins graduate student who is now a postdoctoral student at <a href="https://washu.edu" target="_blank" rel="noreferrer noopener">Washington University</a> in St. Louis.</p>



<p>Interestingly, these adaptations are usually observed when bats counteract external noise, but in this case, the sound processing deficit was internal.</p>



<h2 class="wp-block-heading" id="h-hardwired-adaptation-what-it-means">Hardwired adaptation: What it means</h2>



<p>Despite repeated experiments, the bats' compensation skills didn't refine further, implying these weren't learned behaviors. The adaptations were innate, hardwired into their brain circuits.</p>



<p>The research team was taken aback by the bats' residual hearing, despite a disabled auditory region. Moss theorizes that bats could be leveraging an unidentified auditory pathway or that unaffected neurons could be aiding hearing in ways unknown.</p>



<h2 class="wp-block-heading" id="h-beyond-hearing-role-of-other-senses-of-bats">Beyond hearing: Role of other senses of bats</h2>



<p>This remarkable adaptability raises questions about the role of other senses in bats' navigational prowess. <a href="https://www.earth.com/news/international-bat-appreciation-day-the-crucial-role-of-bats-in-nature/" target="_blank" rel="noreferrer noopener">Bats</a> are known to possess highly sensitive tactile receptors on their wings, enabling them to gather environmental information through subtle air currents. </p>



<p>These tactile cues may offer supplementary, albeit less precise, spatial information when auditory guidance falters. Furthermore, olfactory and visual inputs could contribute to forming a cohesive map of their surroundings, providing a multi-sensory approach to navigation. </p>



<p>Understanding how bats integrate these various sensory inputs enriches our knowledge of their survival strategies and sheds light on the remarkable plasticity of neural pathways in response to sensory impairments.</p>



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



<p>The findings from this study offer novel insights that could influence approaches in human sensory rehabilitation. </p>



<p>Drawing parallels between bats' innate adaptation to auditory deficits and human attempts to cope with sensory loss opens avenues for developing more effective prosthetic devices or training protocols. </p>



<p>Just as bats utilize a combination of residual hearing and other sensory inputs, humans can potentially harness multi-sensory strategies to compensate for deficits, enhancing quality of life. </p>



<p>The research invites further exploration into the brain's capacity for adaptation and may ultimately lead to groundbreaking advancements in sensory repair and augmentation technologies.</p>



<h2 class="wp-block-heading" id="h-insights-into-auditory-processing">Insights into auditory processing </h2>



<p>This study doesn't just highlight how bats navigate through a hearing crisis, but also nudges us to ponder - could this phenomenon hold true for other creatures or even humans?</p>



<p>“You’d think an animal wouldn’t be able to hear at all,” Moss said. “But it suggests that there might be multiple pathways for sound to travel to the auditory cortex.”</p>



<p>Although it's a path less tread, the insights we could gain about auditory processing and adaptive responses in humans could be monumental. It's a thrilling prospect, one that could potentially revolutionize the way we perceive and address sensory deficits in the future.</p>



<p>The study is published in the journal <em><a href="https://www.cell.com/current-biology/abstract/S0960-9822(24)01440-4" target="_blank" rel="noreferrer noopener">Current Biology</a>.</em></p>

Can bats still navigate in the dark without their hearing?

Every living being has a unique way of dealing with...

<p>In the pursuit of a more sustainable future, the scientific community tirelessly works on innovative solutions to confront the plastic crisis. Now, an exciting development paves the way towards a different form of ocean-friendly plastic that promotes environmental sustainability.</p>



<p>The team behind this novel innovation comes from the prestigious RIKEN Center for Emergent Matter Science, led by Takuzo Aida.</p>



<p>The study, published in the journal <em>Science</em>, presents a new plastic variant that is both sturdy and biodegradable with a unique attribute - it disintegrates in seawater. </p>



<p>This means the plastic will not contribute to the mounting issue of microplastic pollution.</p>



<h2 class="wp-block-heading" id="h-understanding-microplastics-and-nanoplastics">Understanding microplastics and nanoplastics</h2>



<p>Current plastics never fully degrade, they shrink and become even more harmful. Microplastics and nanoplastics are tiny pieces of plastic that have broken down from larger plastic items or are manufactured at small sizes. </p>



<p><a href="https://www.earth.com/news/microplastics-are-steadily-increasing-in-freshwater-environments/" target="_blank" rel="noreferrer noopener">Microplastics</a> are generally defined as plastic particles smaller than 5 millimeters, while <a href="https://www.earth.com/news/nanoplastics-can-alter-the-course-of-antibiotics-within-our-body/" target="_blank" rel="noreferrer noopener">nanoplastics</a> are even smaller, typically less than 100 nanometers. </p>



<p>You can find them in everyday products like cosmetics, cleaning supplies, and synthetic clothing, as well as from the degradation of larger plastic debris in the environment. </p>



<p>These minuscule plastics are everywhere -- from the <a href="https://www.earth.com/news/microplastics-found-in-the-tissue-and-skeletons-of-corals/" target="_blank" rel="noreferrer noopener">deepest oceans</a> to the highest mountains -- because they’re so small and lightweight that they easily spread through air, water, and soil.</p>



<p>These tiny particles can be ingested by marine life, birds, and even humans, potentially causing physical harm or introducing harmful chemicals into the food chain. </p>



<p>In ecosystems, they can disrupt habitats and harm organisms that mistake them for food. For humans, there’s ongoing research into the different ways these plastics <a href="https://www.earth.com/news/microplastics-found-in-every-semen-sample-tested/" target="_blank" rel="noreferrer noopener">affect our health</a>.</p>



<h2 class="wp-block-heading" id="h-overcoming-the-plastic-pitfall">Overcoming the plastic pitfall</h2>



<p>Ironically, it is the durability of plastic that is its most desirable feature but this also causes its most significant environmental issue.</p>



<p>Plastics linger in the environment for centuries, wreaking havoc on ecosystems, particularly in the ocean. Traditional plastics, which are non-biodegradable, gradually fragment and contribute enormously to environmental harm.</p>



<p>The current biodegradable counterparts like polylactic acid (<a href="https://www.earth.com/news/biodegradable-plastic-materials-do-not-biodegrade-in-the-ocean/" target="_blank" rel="noreferrer noopener">PLA</a>), while a step forward, remain water insoluble, and fail to degrade in the ocean.</p>



<p>The result is the accumulation of harmful microplastics in our oceans, that threaten <a href="https://www.earth.com/news/microplastic-pollution-found-in-every-aquatic-species-tested/" target="_blank" rel="noreferrer noopener">aquatic life</a> and infiltrate our food chains.</p>



<p>Recognizing these challenges, Aida and his team ventured into the realm of supramolecular plastics. These <a href="https://www.earth.com/news/plastics-may-live-an-immortal-life-thanks-to-new-techniques/" target="_blank" rel="noreferrer noopener">polymers</a>, with structures held together by reversible interactions, provided a new avenue for exploration.</p>



<p>By combining two ionic monomers, the researchers created a new type of plastic that displays both strength and flexibility.</p>



<h2 class="wp-block-heading" id="h-new-plastic-material-in-ocean">New plastic material in ocean</h2>



<p>The initial tests used sodium hexametaphosphate, a common food additive, and different guanidinium ion-based monomers. </p>



<p>Since both monomers can be metabolized by bacteria, the plastic biodegrades once dissolved into its components.</p>



<p>The team found that the key to the stability of these plastics  lies in the use of cross-linked salt bridges. The bonds in the plastics are not weak but rather strong and stable.</p>



<p>The critical discovery was creating cross links that are irreversible - unless exposed to electrolytes like those found in seawater.</p>



<h2 class="wp-block-heading" id="h-creation-of-new-plastics">Creation of new plastics</h2>



<p>After mixing the two monomers in water, the team noticed two separate liquids. One was thick and viscous, containing the necessary cross-linked salt bridges, while the other was watery with salt ions.</p>



<p>The 'desalting' process became a critical step as, without it, the resulting material was a brittle crystal that was unusable as a plastic.</p>



<p>These plastics exhibit an array of desirable characteristics such as non-toxicity, non-flammability, and the capacity to reshape at temperatures above 120°C, similar to other thermoplastics.</p>



<p>Different types of guanidinium sulfates yielded plastics of varying hardnesses and tensile strengths, comparable or even superior to conventional plastics. </p>



<p>The versatility of the plastic suggests that it can be customized according to necessity.</p>



<h2 class="wp-block-heading" id="h-future-of-ocean-friendly-plastics">Future of ocean-friendly plastics</h2>



<p>The researchers also tested the new <a href="https://www.earth.com/news/upcycling-plastic-waste-into-valuable-products/" target="_blank" rel="noreferrer noopener">plastic's recyclability</a> and biodegradability. Astonishingly, they were able to recover 91% hexametaphosphate and 82% guanidinium after dissolving the plastic in salt water.</p>



<p>Soil tests revealed complete degradation of the new plastic over ten days, even proving beneficial by supplying the soil with phosphorous and nitrogen, akin to a fertilizer effect.</p>



<p>“With this new material, we have created a new family of plastics that are strong, stable, recyclable, can serve multiple functions and, importantly, do not generate microplastics,” said Aida.</p>



<p>This powerful innovation exemplifies the possibilities of combining science, ingenuity, and a commitment to sustainability. With these ocean-friendly plastics, we are one step closer to a cleaner, healthier, and more sustainable world.</p>



<h2 class="wp-block-heading" id="h-from-the-lab-to-the-real-world">From the lab to the real world</h2>



<p>While this breakthrough from <a href="https://www.riken.jp/en/research/labs/cems/" target="_blank" rel="noreferrer noopener">RIKEN Center for Emergent Matter Science</a> is exciting, moving it from the lab to real-world use is no small task.</p>



<p>Scaling up production will require fine-tuning the manufacturing process to ensure it's both cost-effective and practical for widespread adoption. </p>



<p>One critical hurdle is how to optimize the desalting step, which plays a vital role in creating the plastic’s unique properties, without driving up production costs. This innovation is a small but significant step toward tackling the massive <a href="https://www.earth.com/news/ocean-plastic-pollution-has-become-a-global-crisis/" target="_blank" rel="noreferrer noopener">plastic problem</a>.</p>



<p>It offers a glimpse of what’s possible when cutting-edge science and environmental responsibility come together. </p>



<p>While challenges remain, this new plastic material could pave the way for a cleaner, healthier world of oceans.</p>

New type of plastic is recyclable and fully dissolves in ocean water

In the pursuit of a more sustainable future, the scientific...

<p>Cold sores are annoying, unwanted, and often catch us off-guard, but new research suggests these small nuisances could be an unexpected caution flag for a much scarier health concern - dementia.</p>



<p>Researchers in Sweden have unearthed a link between cold sores and a heightened risk of developing the memory-stealing ailment.</p>



<p>In a long-term study that followed over a thousand elderly individuals for 15 years, a worrying pattern emerged.</p>



<p>The participants who had endured an infection by HSV-1, the pesky herpes virus that causes cold sores, were twice as likely to fall prey to <a href="https://www.earth.com/news/dementia-was-extremely-rare-in-ancient-times-so-why-is-it-now-so-prevalent/" target="_blank" rel="noreferrer noopener">dementia</a>.</p>



<p>Even though the team couldn't pinpoint a concrete reason for this alarming correlation, they theorized it might lie with the virus's insidious behavior.</p>



<h2 class="wp-block-heading" id="h-cold-sores-harbingers-of-inflammation">Cold sores: harbingers of inflammation?</h2>



<p>Once inside your body, the herpes virus (HSV-1) makes its home in the nerve cells - indefinitely. It gives rise to intermittent flare-ups, which could trigger <a href="https://www.earth.com/news/even-mild-inflammation-can-majorly-damage-the-brain/" target="_blank" rel="noreferrer noopener">inflammation</a> within the nervous system.</p>



<p>This inflammation may stress and harm the delicate tissue within your nervous system and <a href="https://www.earth.com/news/covid-impacts-the-brain-through-inflammation-not-infection/" target="_blank" rel="noreferrer noopener">brain</a>. </p>



<p>Over time, the resulting damage might potentially set the stage for symptoms associated with dementia, like confusion, memory impairment, and gradual breakdown of brain tissue.</p>



<p>This new understanding adds another layer of complexity to the ongoing investigation regarding the link between common <a href="https://www.earth.com/news/viruses-have-eyes-and-ears-on-their-hosts/" target="_blank" rel="noreferrer noopener">viruses</a> and an increased risk of dementia in later life.</p>



<p>In fact, researchers have also implicated the varicella-zoster virus, the culprit behind ailments like chickenpox and shingles, in affecting brain health. </p>



<p>However, the evidence does not point unequivocally towards a positive correlation in this case, and some studies have refuted any link between these viruses and cognitive decline.</p>



<h2 class="wp-block-heading" id="h-hsv-1-and-us-an-unwanted-relationship">HSV-1 and us: an unwanted relationship?</h2>



<p>According to data from Johns Hopkins University, the HSV-1 virus affects between 50 and 80 percent of American adults.</p>



<p>Although closely related, this virus is distinct from HSV-2, the pathogen involved in sexually transmitted herpes. </p>



<p>HSV-1 primarily spreads through intimate contact such as <a href="https://www.earth.com/news/bizarre-history-of-kissing-it-wasnt-always-romantic/" target="_blank" rel="noreferrer noopener">kissing</a> or oral sex, and can even pass from mother to child in the womb, potentially causing serious side effects in children.</p>



<h2 class="wp-block-heading" id="h-hsv-1-a-manageable-menace">HSV-1: a manageable menace?</h2>



<p>Once infected, the symptoms can be mild and manageable. </p>



<p>Usual initial signs include a fever, swollen lymph nodes, a sore throat, and sores on the mouth and gums.</p>



<p>After the first flare-up, symptoms can disappear entirely, only to reappear periodically as a red, ulcerous sore on the mouth or lip. </p>



<p>In such instances, doctors usually prescribe antiviral medication or suggest over-the-counter painkillers to alleviate the discomfort and manage inflammation.</p>



<p>For the longest time, we were under the impression that these unsightly cold sores were the only lingering effects of HSV-1, but recent years have brought a more sinister link to light.</p>



<h2 class="wp-block-heading" id="h-the-swedish-study-cold-sores-and-dementia-risk">The Swedish study: cold sores and dementia risk</h2>



<p>The team of researchers who brought this potential link to our attention hail from <a href="https://www.uu.se/en" target="_blank" rel="noreferrer noopener">Uppsala University</a> and published their findings in the <em>Journal of Alzheimer’s Disease</em> in December 2023.</p>



<p>Their rigorous study followed 1,002 Swedes, of which 80 percent carried HSV-1, over a 15-year span. </p>



<p>By the end of the study, 32 subjects had developed Alzheimer's disease and 63 percent developed some form of dementia - representing 11 percent of the participants in total.</p>



<p>The majority of these individuals, about 89 percent, had herpes.</p>



<p>Even though the team took into account factors like education and genetic predisposition to Alzheimer's, they were unable to adjust for the effect of age or the potential impact of other health concerns like heart disease and diabetes.</p>



<h2 class="wp-block-heading" id="h-a-tale-of-two-studies">A tale of two studies</h2>



<p>The Uppsala study is not the first to explore the relationship between herpes and dementia. </p>



<p>A 2024 study from South Korea involving over 750,000 participants also found that those with HSV and the varicella-zoster virus were more likely to develop dementia.</p>



<p>However, a 2019 review from several UK universities found the link between dementia and HSV-1 inconclusive, and it failed to establish a strong association.</p>



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



<p>Dr Jagan PillaI from the Cleveland Clinic believes the studies are not convincing enough to conclude that herpes could cause dementia. </p>



<p>Regarding the 2019 UK study, he suggests that we need better quality studies in future.</p>



<p>Along the same lines, Dr Monica Gandhi, an infectious disease specialist at UC San Francisco, points out that herpes infection rates are significantly higher than dementia rates, casting doubt on a potential connection.</p>



<p>"Given how common herpes virus infection is [in] young people, I would not let this study concern you too much," she states, reassuringly. </p>

Cold sores and dementia: The unexpected connection

Cold sores are annoying, unwanted, and often catch us off-guard,...

<p>Is America losing its battle against obesity? According to recent data, around 72-75% of U.S. adults are either overweight or obese. </p>



<p>The harsh reality is that approximately 86 million people struggle to maintain a healthy body mass index (BMI) of under 25.</p>



<p>This alarming statistic, as described by the researchers in a new study, is nothing short of an "epidemic."</p>



<p>The findings highlight how these trends have become steadily worse over decades, signaling a persistent public health crisis.</p>



<h2 class="wp-block-heading" id="h-obesity-rates-in-america">Obesity rates in America</h2>



<p>Despite this bleak prognosis, there may still be a silver lining in sight. Separate research conducted by the CDC hints towards a possible decline in <a href="https://www.earth.com/news/childhood-obesity-rates-spiked-during-the-pandemic/" target="_blank" rel="noreferrer noopener">obesity rates</a>, referred to as the "Ozempic effect."</p>



<p>The CDC's national survey, spanning from 2021 to 2023, provides a glimpse into the most recent health trends and shines a ray of hope that mitigates some of the concern arising from the raw data.</p>



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



<p>Why is there this large-scale concern over obesity? The answer lies in the myriad <a href="https://www.earth.com/news/obesity-now-affects-more-than-a-billion-people/" target="_blank" rel="noreferrer noopener">health issues</a> that come part and parcel with being overweight, such as diabetes, heart disease, and cancer.</p>



<p>Moreover, the burden of obesity extends beyond the individual, as healthcare costs related to obesity totaled a staggering $481 billion in 2016. </p>



<p>The mounting costs and the rising tide of obesity are fueled by several factors, including the accessibility and affordability of healthy, fresh food and the consumer's choice to eat processed foods that are <a href="https://www.earth.com/news/the-average-american-consumes-80-pounds-of-sugar-per-year/" target="_blank" rel="noreferrer noopener">high in sugar</a> and fat.</p>



<h2 class="wp-block-heading" id="h-failure-to-tackle-the-epidemic">Failure to tackle the epidemic </h2>



<p>This comprehensive study on obesity rates in America was published recently in the journal <em>The Lancet</em>. The experts collated data from 134 sources that dated from 1980 to 2021.</p>



<p>The research was conducted by a team of over 100 scientists from international organizations, forming a group known as the GBD 2021 U.S. Obesity Forecasting Collaborators.</p>



<p>The CDC's surveys, Gallup polls and long-term studies, like Women's Health Across the Nation, were all part of the rich mosaic of data sources used to curate this extensive research material.</p>



<p>Study lead author Professor Emmanuela Gakidou is an expert in the Institute for Health Metrics and Evaluation (IHME) at the <a href="https://www.washington.edu/" target="_blank" rel="noreferrer noopener">University of Washington</a>.  </p>



<p>“Our analysis lays bare the decades-long failure to tackle the growing overweight and obesity epidemic in the USA," said Professor Gakidou.</p>



<p>"The catastrophic consequences of the surge in overweight and obesity among children are already evident in the rising prevalence of childhood hypertension and type 2 diabetes."</p>



<h2 class="wp-block-heading" id="h-future-of-obesity-in-america">Future of obesity in America</h2>



<p>The research team devised maps depicting areas of obesity prevalence from 1990 to 2021, after segregating data by age and gender. </p>



<p>The experts further extrapolated these trends and built a model to predict scenarios for the next 25 years.</p>



<p>The model predicts that, by 2050, there will be 43.1 million obese or <a href="https://www.earth.com/news/being-overweight-makes-it-harder-for-brain-to-resist-unhealthy-food/" target="_blank" rel="noreferrer noopener">overweight</a> children and adolescents, and 213 million obese or overweight adults. </p>



<p>This translates to one in three adolescents and two in three adults who will be grappling with obesity.</p>



<p>The most concerning revelation was the increasing trend of obesity among children. </p>



<p>According to research from the <a href="https://illinois.edu/" target="_blank" rel="noreferrer noopener">University of Illinois</a>, children struggling with their weight are more likely to develop health issues like diabetes, heart disease, high blood pressure, and psychological problems.</p>



<p>They also have a higher risk of dying young compared to children of average weight.</p>



<h2 class="wp-block-heading" id="h-role-of-pop-culture">Role of pop culture</h2>



<p>Modern pop culture has played a pivotal role in shaping perceptions about food intake and obesity in America.</p>



<p>Muk-bang creators like Nicholas Perry, better known by his username Nikocado Avocado, share videos of themselves binging on massive amounts of food, consuming more than 10,000 calories in a single sitting. </p>



<p>These motivations are predominantly monetary, with Perry amassing 150 pounds and a net worth of $2 million over seven years as a food creator.</p>



<p>However, this trend is not without its casualties. The grim reality of <a href="https://www.earth.com/news/binge-eating-linked-to-a-specific-set-of-brain-cells/" target="_blank" rel="noreferrer noopener">binge eating</a> was highlighted by the tragic death of TikToker Brittany Sauer, who felt she had "ruined her life" with binge eating.</p>



<h2 class="wp-block-heading" id="h-call-for-institutional-change">Call for institutional change</h2>



<p>While there have been recent strides made in weight loss - especially with more people turning to GLP-1 inhibitors like Ozempic - experts suggest that institutional change is necessary to curb obesity in America.</p>



<p>Changes could include everything from widening insurance coverage for weight loss procedures to tightening regulations on sugar and fat content in consumer products, and even making healthy options more affordable.</p>



<p>Public health campaigns focusing on education and awareness are also critical to empowering individuals to make healthier lifestyle choices.</p>



<p>"Without major reform, the forecasted trends will be devastating at the individual and population level, and the associated disease burden and economic costs will continue to escalate," concluded the researchers.</p>



<p>The full study is published in <a href="https://www.healthdata.org/news-events/newsroom/news-releases/lancet-without-immediate-action-nearly-260-million-people-usa#:~:text=Continuation%20of%20these%20trends%20would,%25%20to%2082.1"><em>The Lancet</em></a>.</p>

75% of U.S. adults are overweight in what doctors are now calling "an epidemic"

Is America losing its battle against obesity? According to recent...

<p>Once purely the stuff of science fiction, we are steadily realizing that our primate cousins, the chimpanzees, have been quietly upgrading their technology tools. </p>



<p>They have been doing so for thousands of years, and it seems their progress is fueled by the exchange of ideas through migrations among different populations. </p>



<h2 class="wp-block-heading" id="h-art-of-tool-use-in-chimpanzees">Art of tool use in chimpanzees</h2>



<p>While chimpanzees might not develop smartphones or launch spaceships anytime soon, they have been exhibiting an intriguing trend. </p>



<p>Gradually, <a href="https://www.earth.com/news/chimpanzee-cultures-are-more-complex-than-we-realized/" target="_blank" rel="noreferrer noopener">chimps</a> are enhancing their tool-using prowess, a process that has transpired over epochs - quite similar to us humans. </p>



<p>In fact, the study proposes the idea that our distant ape ancestors also utilized the power of social networks to better their technologies.</p>



<h2 class="wp-block-heading" id="h-the-amazing-chimpanzee-realm">The amazing chimpanzee realm</h2>



<p>The scientists were enthralled by the observation that <a href="https://www.earth.com/news/chimpanzees-feel-the-pressure-to-perform-with-an-audience/" target="_blank" rel="noreferrer noopener">chimps</a> have a knack for performing complex tasks such as tool use and then passing these skills onto the next generation. Now, that's quite a feat for a creature that many still consider to be "less evolved."</p>



<p>But here's the twist. Despite us humans progressing from stone tools to space shuttles, the chimp "culture" - defined as socially learned behaviors - appeared somewhat stuck in time.</p>



<p>And this is precisely what Cassandra Gunasekaram, a doctoral student at the University of Zurich, decided to question.</p>



<h2 class="wp-block-heading" id="h-chimpanzees-use-connections-to-upgrade-tools">Chimpanzees use connections to upgrade tools</h2>



<p>The researchers combined genetic data from historic chimpanzee migrations across Africa with observations of 15 unique foraging <a href="https://www.earth.com/news/chimpanzees-use-rapid-gestures-in-conversations-like-humans/" target="_blank" rel="noreferrer noopener">behaviors</a> across various populations and sub-groups.</p>



<p>The behaviors were segmented into three categories: those requiring no tools, those needing simple tools, and those involving complex toolsets.</p>



<p>The researchers were particularly impressed by the Congo chimps' remarkable toolset use, where they utilized a sturdy stick to bore a tunnel into the ground to reach termite nests. </p>



<p>Then, with a plant stem modified into a brush by chewing, they would "fish" for termites in the tunnel they created.</p>



<h2 class="wp-block-heading" id="h-catalysts-for-enhanced-tool-use">Catalysts for enhanced tool use</h2>



<p>The study unveiled that advanced tool use was significantly linked to populations connected by genetic exchanges over the last 5,000–15,000 years. </p>



<p>This stirred the idea that such behaviors proliferated when groups interacted. The most complex tool use was observed where three subspecies overlapped, demonstrating how inter-group relations enrich cultural knowledge.</p>



<p>On the other hand, simpler behaviors, such as foraging without tools, appear less associated with migration and likely evolved autonomously in different regions.</p>



<h2 class="wp-block-heading" id="h-humans-chimpanzees-and-tool-evolution">Humans, chimpanzees, and tool evolution</h2>



<p>Gunasekaram hammers home how this mirrors our own species' journey wherein the exchange of ideas and incremental innovation have been pivotal to our technological leaps - right from the humble abacus to the modern smartphone.</p>



<p>"They've become so complex that one person alone could not reinvent them from scratch," Gunasekaram said.</p>



<p>Yet, unlike humans, chimps have sparse chances to meet new individuals and ideas. This is mainly because migrations unfold slowly, propelled by sexually mature females relocating to new communities to evade inbreeding.</p>



<h2 class="wp-block-heading" id="h-overcoming-the-challenges">Overcoming the challenges</h2>



<p>Turning to ancient genetic flows analysis helped the research team tackle one of the largest hurdles in studying the evolution of <a href="https://www.earth.com/news/chimpanzees-continue-learning-as-adults/" target="_blank" rel="noreferrer noopener">chimpanzee</a> culture: the limited observation window. </p>



<p>This historical data was important considering that we have been scientifically studying the species for only around a century.</p>



<p>Moreover, as Gunasekaram pinpointed, chimpanzee tools consist of perishable materials like sticks and stems, making it nearly impossible to track how their artifacts have evolved over time.</p>



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



<p>So, are we anticipating chimps matching human ingenuity? Highly unlikely. But given enough time, they could potentially become more efficient foragers.</p>



<p>Already, some populations show advancements in cracking nuts with stone-made hammers and anvils. One group has even invented a stabilizer for the anvil, according to Gunasekaram.</p>



<p>Indeed, this research reveals that chimpanzees' tool-using capabilities embody a form of "culture" - one that is dynamic, adaptable, and, most importantly, unique to separate communities.</p>



<p>Who knows what other surprises our primate counterparts might have in store as they continue to evolve through the ebbs and flows of time?</p>



<p>The study titled "Population connectivity shapes the distribution and complexity of chimpanzee cumulative culture" is published in the journal <a href="https://www.science.org/doi/10.1126/science.adk3381" target="_blank" rel="noreferrer noopener"><em>Science</em></a>.</p>

Chimpanzees are constantly mastering new tools

<p>In the midst of our busy lives, those seemingly insignificant everyday experiences - like booking a flight home for Thanksgiving or writing a thank-you note - may feel less meaningful.</p>



<p>But according to Erin Westgate, assistant professor of psychology at the University of Florida, these experiences carry more value than we attribute them.</p>



<h2 class="wp-block-heading" id="h-purpose-behind-the-research">Purpose behind the research</h2>



<p>Alongside her team at the <a href="https://socialcognition.psych.ufl.edu" target="_blank" rel="noreferrer noopener">Florida Social Cognition and Emotion Lab</a>, Westgate recently secured a grant from the National Science Foundation.</p>



<p>The researchers intended to examine why people underestimate the significance of future life <a href="https://www.earth.com/news/facial-expressions-arent-enough-to-understand-human-emotions/" target="_blank" rel="noreferrer noopener">experiences</a>. The spark for this exploration ignited during Westgate's school days.</p>



<p>“This started a long time ago when I was in grad school where I was talking to another student who asked me if we know how meaningful events will be in the future,” Westgate said.</p>



<h2 class="wp-block-heading" id="h-meaningful-experience-of-thanksgiving">Meaningful experience of Thanksgiving</h2>



<p>The question prompted an interesting study involving <a href="https://www.virginia.edu" target="_blank" rel="noreferrer noopener">University of Virginia</a> undergraduates. The students were asked about their expectations of the upcoming Thanksgiving holiday's meaningfulness and their thoughts afterward. </p>



<p>“Surely people know how significant Thanksgiving will be, right? It’s the poster child for gratitude and meaning,” Westgate said.</p>



<p>Much to Westgate's surprise, the students extensively misjudged their <a href="https://www.earth.com/news/social-media-likes-have-a-strong-emotional-effect-on-young-people/" target="_blank" rel="noreferrer noopener">feelings</a> about the holiday.</p>



<h2 class="wp-block-heading" id="h-missing-out-on-meaningful-experiences">Missing out on meaningful experiences </h2>



<p>Fast forward to the pandemic-ridden 2020. Westgate revisited her initial findings, asking, “We found it once, but can we find it again?”</p>



<p>With a larger sample of University of Florida undergraduates, the results echoed the first study. People chronically underestimated the value of their Thanksgiving holiday.</p>



<p>“We want to live meaningful lives, we want to do meaningful things and so if we are not realizing that an experience is going to be meaningful, we may be less likely to do it and miss out on these potential sources of meaning in our own lives,” Westgate said.</p>



<h2 class="wp-block-heading" id="h-decision-factors-in-meaningful-experiences">Decision factors in meaningful experiences</h2>



<p>The research indicated a key factor in decision-making - anticipated <a href="https://www.earth.com/news/mixed-emotions-linked-to-unique-brain-activity/" target="_blank" rel="noreferrer noopener">feelings</a>.</p>



<p>Whether it's a life-altering decision like a career choice or a family start, or a minor one like attending a holiday event, our decisions lean towards promoting a sense of purpose and fulfillment.</p>



<p>Over the course of a three-year study, Westgate aims to condense the reasons behind our underestimation of experiences - from our career choices to the seemingly mundane task of writing thank-you notes.</p>



<p>The research considers both positive and negative experiences, including the acceptance or rejection of medical school applications.</p>



<h2 class="wp-block-heading" id="h-making-sense-of-events">Making sense of events</h2>



<p>The study also explores personal growth experiences that entail discomfort, leading to avoiding certain decisions out of fear.</p>



<p>Still, these very decisions could play an instrumental role in developing resilience and yielding deep satisfaction.</p>



<p>“We don’t make sense of events until they actually happen. We don’t process events until we need to, when they actually happen and not before,” said Westgate. Jumping the gun might lead us to underestimate the potential meaning of certain events.</p>



<h2 class="wp-block-heading" id="h-seeking-solutions-for-underestimation">Seeking solutions for underestimation</h2>



<p>The research aims to go beyond merely identifying problems; it seeks actionable solutions. Many of us often overlook the true value of meaningful experiences. </p>



<p>This oversight can lead to a less fulfilling life, as we fail to appreciate the depth and significance of our everyday moments. By delving into the reasons behind this underestimation, Westgate’s work strives to illuminate the cognitive biases and misconceptions that cloud our perception of meaning.</p>



<p>Understanding the root of these misconceptions is crucial. It involves exploring psychological patterns and societal influences that lead individuals to undervalue their <a href="https://www.earth.com/news/emotional-intelligence-may-be-secret-to-academic-success/" target="_blank" rel="noreferrer noopener">experiences</a>. </p>



<p>By identifying these patterns, the research can offer strategies to shift our perspectives and encourage a deeper appreciation of our lives. This shift could not only enhance individual well-being but also promote a more profound connection with others and the world around us.</p>



<h2 class="wp-block-heading" id="h-harnessing-meaningful-experiences-in-daily-life">Harnessing meaningful experiences in daily life</h2>



<p>The findings suggest that by becoming more aware of our tendency to underestimate the meaningfulness of experiences, individuals can purposefully cultivate more fulfilling daily lives.</p>



<p>Simple changes, such as being more present in the moment, keeping a gratitude journal, or actively reflecting on past experiences, can enhance appreciation for life's ordinary events. </p>



<p>These practices can help individuals recognize the intrinsic value in seemingly minor experiences, thereby enriching personal happiness and well-being.</p>



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



<p>The research carries significant implications for psychological interventions aiming to promote mental well-being. Interventions could focus on enhancing awareness of meaningful experiences and encouraging individuals to engage in activities that nurture a sense of purpose.</p>



<p>By integrating these insights into therapy and counseling, mental health practitioners can better support clients in recognizing and capitalizing on the meaningful dimensions of their lives, potentially improving mental resilience and overall life satisfaction.</p>



<p>“Sometimes we go into a project, and we know what we are going to find. This is one of those projects that surprised us,” concluded Westgate.</p>

We often undervalue the most meaningful experiences in life

In the midst of our busy lives, those seemingly insignificant...

<p>A recent fossil discovery may revolutionize our understanding of bird brain evolution, shedding light on how the intelligence of modern birds developed.&nbsp;</p>



<p>Researchers from the <a href="https://www.cam.ac.uk/" target="_blank" rel="noreferrer noopener">University of Cambridge</a> and the Natural History Museum of Los Angeles County have identified a remarkably well-preserved <a href="https://www.earth.com/news/terror-bird-phorusrhacid-discovery-was-largest-meat-eating-bird-of-its-time/" target="_blank" rel="noreferrer noopener">bird</a> fossil from the Mesozoic Era, approximately 80 million years old, named <em>Navaornis hestiae</em>.&nbsp;</p>



<p>This ancient bird’s complete skull, roughly the size of a starling’s, was found in Brazil and offers a rare and detailed glimpse into the brains of early avian species.</p>



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



<p>Scientists believe that <em>Navaornis hestiae</em> could serve as a kind of “Rosetta Stone” for understanding <a href="https://www.earth.com/news/how-birds-brains-evolved-to-enable-them-to-fly/" target="_blank" rel="noreferrer noopener">avian brain evolution</a>.&nbsp;</p>



<p>The fossilized skull bridges a 70-million-year gap in the evolutionary timeline between the 150-million-year-old <em>Archaeopteryx</em>, one of the earliest bird-like dinosaurs, and today’s birds.&nbsp;</p>



<p>Its well-preserved structure has enabled researchers to digitally reconstruct the brain and understand the evolutionary steps leading to the unique cognitive abilities of modern birds.</p>



<p>“The brain structure of <em>Navaornis</em> is almost exactly intermediate between <em>Archaeopteryx</em> and modern birds,” said co-lead author Guillermo Navalón from Cambridge’s Department of Earth Sciences. “It was one of these moments in which the missing piece fits absolutely perfectly.”&nbsp;</p>



<p>The skull’s preservation allowed for advanced micro-CT scanning, revealing a brain structure that suggests it had a larger cerebrum than <em>Archaeopteryx</em>, hinting at advanced cognitive functions not yet seen in other ancient bird-like dinosaurs.</p>



<h2 class="wp-block-heading" id="h-insights-into-cognitive-evolution">Insights into cognitive evolution</h2>



<p>While <em>Navaornis</em> was equipped with a more developed cerebrum, its cerebellum - a critical area for flight control in modern birds - was less evolved, indicating that its flight capabilities may have been simpler.&nbsp;</p>



<p>“<a href="https://www.earth.com/news/modern-bird-feathers-contain-traces-of-dinosaur-feathers/" target="_blank" rel="noreferrer noopener">Modern birds</a> have some of the most advanced cognitive capabilities in the animal kingdom, comparable only with mammals,” said senior author Daniel Field, a paleontologist at Cambridge.&nbsp;</p>



<p>But understanding how and when these traits evolved has been elusive until now.&nbsp;</p>



<p>The fossil offers direct insight into an important transitional phase for bird cognition, suggesting that <em>Navaornis</em> might have been capable of complex behaviors like finding food, shelter, or even engaging in elaborate social interactions.</p>



<h2 class="wp-block-heading" id="h-abilities-of-opposite-birds">Abilities of “opposite birds”</h2>



<p>Though <em>Navaornis</em> has some similarities to modern birds, it belongs to a group called enantiornithines, or “opposite birds,” which diverged from modern avians more than 130 million years ago.&nbsp;</p>



<p>Enantiornithines had developed feathers and could likely fly, but they lacked some of the brain features essential for the precise flight control seen in living birds.&nbsp;</p>



<p>“This discovery shows that some of the birds flying over the heads of dinosaurs already had a fully modern skull geometry more than 80 million years ago,” said lead author Luis Chiappe from the Natural History Museum of Los Angeles County.&nbsp;&nbsp;</p>



<p>But the brain anatomy of <em>Navaornis</em> raises new questions about how opposite birds achieved flight without the advanced cerebellar structures seen in contemporary birds.</p>



<h2 class="wp-block-heading" id="h-a-perfectly-preserved-fossil">A perfectly preserved fossil</h2>



<p>Navaornis was discovered by William Nava, director of the Museum of Paleontology in Marília, Brazil, at a site that tens of millions of years ago likely consisted of slow-moving creeks, creating the ideal conditions for fossil preservation.&nbsp;</p>



<p>This discovery marks the fourth major Mesozoic bird fossil identified by Field’s team, following <em>Ichthyornis</em>, <em>Asteriornis</em> (also called the “Wonderchicken”), and <em>Janavis</em>.&nbsp;</p>



<p>Each of these fossils has been pivotal in helping to reconstruct the evolutionary path of birds, the most diverse group of living vertebrate animals.</p>



<p>Navalón, who co-led the study, expressed awe at the specimen’s remarkable state: “This fossil is truly so one-of-a-kind that I was awestruck from the moment I first saw it to the moment I finished assembling all the skull bones and the brain.”&nbsp;</p>



<p>The research team hopes that this fossil’s exceptional quality is just the beginning; additional findings at this Brazilian site could yield even more insights into avian evolution.</p>



<h2 class="wp-block-heading" id="h-advancing-our-understanding-of-bird-cognition">Advancing our understanding of bird cognition</h2>



<p>“This might be just one fossil, but it’s a key piece in the puzzle of bird brain evolution,” Field said.&nbsp;</p>



<p>With the findings on <em>Navaornis</em>, researchers now have a clearer picture of the evolutionary transitions that led from early bird-like dinosaurs to today’s intelligent avian species, such as <a href="https://www.earth.com/news/crows-hold-grudges-for-up-to-17-years/" target="_blank" rel="noreferrer noopener">crows</a> and parrots.&nbsp;</p>



<p>Still, the discovery is just a first step. Future studies will focus on understanding <em>Navaornis</em>’s behavior and interaction with its environment, aiming to answer broader questions about how bird cognition has developed over time.</p>



<h2 class="wp-block-heading" id="h-an-early-era-in-bird-evolution">An early era in bird evolution</h2>



<p>The team’s ongoing research on Mesozoic bird fossils combined with advanced imaging techniques is providing an unprecedented view of the evolutionary leaps in bird anatomy and cognition.&nbsp;</p>



<p>The next steps include investigating how <em>Navaornis</em> and its contemporaries adapted to their surroundings and exploring whether their evolving brain structures offered an advantage in survival and <a href="https://www.earth.com/news/birds-social-networks-greatly-influence-their-food-choices/" target="_blank" rel="noreferrer noopener">social behavior</a>.</p>



<p>This discovery stands as a significant milestone in the field, offering a unique window into an era when birds were just beginning to develop the traits that would eventually make them some of the most cognitively advanced animals on Earth.&nbsp;</p>



<p>With continued research, <em>Navaornis hestiae</em> may reveal even more about the mysteries of bird brain evolution, helping scientists piece together the fascinating journey from ancient feathered dinosaurs to the vibrant bird species we see today.</p>



<p>The study is published in the journal <a href="https://www.nature.com/articles/s41586-024-08114-4" target="_blank" rel="noreferrer noopener"><em>Nature</em></a><em>.</em></p>

<p>Welcome to a world where climate change adaptation isn't just about doomsday scenarios and mitigations. </p>



<p>Rather, it's a world where we utilize our creativity, envision future possibilities, and work towards desirable and resilient outcomes. </p>



<p>This concept has been echoed by ten pioneering scientists in an article published in one of the prestigious <em>Nature Partner Journals</em>.</p>



<p>"We scientists should not merely outline doomsday scenarios, but create a vision for people to believe in and work towards," said Professor Chris Zevenbergen from <a href="https://www.tudelft.nl/en/" target="_blank" rel="noreferrer noopener">Delft University of Technology</a>, one of the study's lead authors.</p>



<p>This radical shift of focus is a potential game-changer, particularly for the vulnerable urban river deltas.</p>

<p>Urban river deltas - regions of immense social and economic significance - are at the mercy of the escalating <a href="https://www.earth.com/news/climate-crisis-global-supply-chains-face-25-trillion-in-losses/" target="_blank" rel="noreferrer noopener">climate crisis</a>. Rising sea levels, extreme weather events, and soil subsidence pose constant threats.</p>



<p>While affluent regions like the Netherlands grapple with escalating costs and complexity to overhaul existing systems, deltas in low- and middle-income countries also wrestle with rapid urbanization and scarce resources.</p>



<p>Traditional mitigation models seem inadequate to furnish these deltas for an uncertain future. </p>



<p>The solution, as Zevenbergen suggests, lies in evolving more flexible approaches and using <a href="https://www.earth.com/news/new-technology-can-visually-depict-what-we-are-imagining/" target="_blank" rel="noreferrer noopener">imagination</a> and "design-based research."</p>



<p>"Ask the wider society: what do we want our country to look like in 100 years? What do we really care about? And then visualize possible futures," suggests Zevenberger.</p>



<p>This stimulates civic engagement and makes climate adaptation both tangible and motivating.</p>



<h2 class="wp-block-heading" id="h-the-netherlands-as-a-role-model">The Netherlands as a role model</h2>



<p>What if we could draw lessons from successful models? </p>



<p>The Netherlands, as the authors noted, could serve as an exemplary model for deltas worldwide.</p>



<p>The country's "Delta Works," a visionary program designed by Johan van Veen, stands as an example of future-facing vision and deep understanding of <a href="https://www.earth.com/news/food-production-affects-earths-natural-processes/" target="_blank" rel="noreferrer noopener">natural processes</a>.</p>



<p>"Johan van Veen did not think in years, but in generations; he had deep knowledge of natural processes; and he had an appealing vision for the future," explained Zevenbergen.</p>



<p>This understanding of the dynamic natural processes, coupled with long-term thinking, can be a compelling force for positive change.</p>



<p>The authors, however, caution that these efforts should be seen as a step in the process, and not a permanent solution.</p>



<p>They urge us to adapt, envision, and innovate continually, using the power of design and <a href="https://www.earth.com/news/global-climate-adaptation-lacks-coordination/" target="_blank" rel="noreferrer noopener">imagination</a> to shape our coasts and our future.</p>



<h2 class="wp-block-heading" id="h-integration-of-imagination-in-climate-adaptation">Integration of imagination in climate adaptation </h2>



<p>The capacity to imagine and create should become integral to delta management. </p>



<p>Scientists must interweave imagination and interdisciplinary approaches with climate adaptation research.</p>



<p>Policymakers are encouraged to invest in vision and creative research, as these aspirational plans could translate into a significant economic impact when put into practice.</p>



<p>The role of education is equally crucial. Universities should cultivate creativity and nurture "design thinking" among students, empowering them to conceive and realize visionary solutions for the future.</p>



<p>"We want students with the ability to create and the motivation to realise visions of the future: who seek large-scale and unique solutions," said Zevenbergen.</p>



<p>This thought-provoking article by the ten scientists working at Delft University of Technology challenges us to reimagine our approach towards climate change adaptation. </p>



<p>The power to reshape the future, it appears, lies just as much in our minds and our creative capacities as it does in the physical measures we take.</p>



<h2 class="wp-block-heading" id="h-empowering-communities-to-shape-climate-resilience">Empowering communities to shape climate resilience</h2>



<p>While scientists, policymakers, and educators play critical roles in climate adaptation, active participation by local communities cannot be overlooked.</p>



<p>Engaging the people most affected by climate change is essential for creating effective and inclusive <a href="https://www.earth.com/news/nature-based-climate-solutions-are-now-more-critical-than-ever/" target="_blank" rel="noreferrer noopener">solutions</a>. </p>



<p>Communities living in urban river deltas often possess deep, lived knowledge of their environments, which can guide more culturally relevant and practical designs.</p>



<p>Participatory workshops, citizen science initiatives, and co-design projects are powerful tools for bridging the gap between experts and the public. </p>



<p>These approaches build trust and empower residents to take ownership of climate adaptation strategies.</p>



<p>For instance, in regions like Bangladesh's Ganges-Brahmaputra Delta, local input has been instrumental in developing adaptive strategies that integrate traditional knowledge with modern innovation.</p>



<p>By embedding community-driven processes into delta management, societies can craft solutions that are both visionary and grounded in reality, ensuring that resilience is not just a scientific ambition but a shared societal goal.</p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



<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>

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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



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



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



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