<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>A breakthrough clinical trial has revealed that an injection given during asthma and COPD (chronic obstructive pulmonary disease) flare-ups is significantly more effective than the traditional treatment of steroid tablets.&nbsp;</p>



<p>According to findings published in <a href="https://www.thelancet.com/journals/lanres/article/PIIS2213-2600(24)00299-6/fulltext" target="_blank" rel="noreferrer noopener"><em>The Lancet Respiratory Medicine</em></a>, the injection reduces the need for further treatment by 30%, offering a potential “game-changing” solution for millions worldwide.</p>



<p><a href="https://www.earth.com/news/nearly-one-third-of-asthma-cases-linked-to-air-pollution/">Asthma</a> and COPD flare-ups, known as exacerbations, can be life-threatening. In the UK alone, four people with asthma and 85 with COPD tragically lose their lives each day.&nbsp;</p>



<p>These conditions are not only deadly but also widespread, with someone in the UK experiencing an asthma attack every 10 seconds. Combined, asthma and COPD cost the NHS £5.9 billion annually.</p>



<h2 class="wp-block-heading" id="h-targeted-approach-to-asthma-treatment-nbsp">Targeted approach to asthma treatment&nbsp;</h2>



<p>The injection specifically targets “eosinophilic exacerbations,” which account for up to 30% of COPD flare-ups and nearly 50% of asthma attacks.&nbsp;</p>



<p>These exacerbations result from inflammation caused by elevated levels of eosinophils, a type of white blood cell, leading to symptoms such as wheezing, coughing, and chest tightness.</p>



<p>Historically, the standard treatment for such flare-ups has been steroids like prednisolone, which reduce lung inflammation. However, these drugs come with significant side effects, including an increased risk of <a href="https://www.earth.com/news/exercise-can-counteract-the-genetic-risk-for-diabetes/" target="_blank" rel="noreferrer noopener">diabetes</a> and osteoporosis.&nbsp;</p>



<p>Furthermore, many patients do not respond adequately to steroids, leading to repeated hospitalizations or, in severe cases, death within 90 days of treatment.</p>



<h2 class="wp-block-heading" id="h-testing-the-new-asthma-treatment-nbsp">Testing the new asthma treatment&nbsp;</h2>



<p>The ABRA trial, led by researchers from <a href="https://www.kcl.ac.uk/" target="_blank" rel="noreferrer noopener">King's College London</a>, tested the efficacy of a <a href="https://www.earth.com/news/experts-have-found-powerful-antibodies-that-neutralize-all-covid-variants/" target="_blank" rel="noreferrer noopener">monoclonal antibody</a> called benralizumab, already approved for managing severe asthma.&nbsp;</p>



<p>The drug targets eosinophils, reducing lung inflammation. For the trial, the drug was repurposed as a one-time injection administered during exacerbations.</p>



<p>The multi-center trial, conducted at <a href="https://www.ouh.nhs.uk/" target="_blank" rel="noreferrer noopener">Oxford University Hospitals NHS Foundation Trust</a> and <a href="https://www.guysandstthomas.nhs.uk/" target="_blank" rel="noreferrer noopener">Guy's and St Thomas' NHS Foundation Trust</a>, randomized participants into three groups.</p>



<p>One group received the benralizumab injection with placebo tablets, while another received standard steroid treatment (prednisolone) with a placebo injection. The third group received both the injection and standard care.</p>



<p>As a double-blind, placebo-controlled study, neither the participants nor the researchers knew which treatment was being administered.</p>



<h2 class="wp-block-heading" id="h-game-changing-treatment-for-people-with-asthma-nbsp">Game-changing treatment for people with asthma&nbsp;</h2>



<p>The results were striking. After 28 days, participants in the benralizumab group showed significant improvements in respiratory symptoms such as coughing, wheezing, and breathlessness compared to those receiving steroids.&nbsp;</p>



<p>By the 90-day mark, treatment failure rates were four times lower in the benralizumab group than in the steroid group.</p>



<p>Not only did the injection reduce the need for doctor visits or hospitalizations, but it also improved patients' overall quality of life.</p>



<p>“This could be a game-changer for people with asthma and COPD,” said Professor Mona Bafadhel, lead investigator of the trial.&nbsp;</p>



<p>“Treatment for asthma and COPD exacerbations has not changed in 50 years despite causing 3.8 million deaths worldwide a year combined. The big advance in the ABRA study is the finding that targeted therapy works in asthma and COPD attacks.”</p>



<h2 class="wp-block-heading" id="h-a-safe-and-versatile-treatment">A safe and versatile treatment</h2>



<p>The study demonstrated that benralizumab is safe, with no significant side effects compared to past studies of the drug. </p>



<p>While healthcare professionals administered the injections during the trial, the drug could potentially be delivered at home, in GP practices, or in emergency departments in the future.</p>



<p>Professor Bafadhel emphasized the importance of personalized treatment: “Instead of giving everyone the same treatment, we found targeting the highest risk patients with very targeted treatment, with the right level of inflammation, was much better than guessing what treatment they needed.”</p>



<h2 class="wp-block-heading" id="h-addressing-a-critical-need-in-lung-health">Addressing a critical need in lung health</h2>



<p>The findings underscore a critical gap in research and treatment for <a href="https://www.earth.com/news/viruses-can-hide-in-lung-cells-and-cause-chronic-disease/" target="_blank" rel="noreferrer noopener">lung</a> conditions. Dr. Samantha Walker, Director of Research and Innovation at <a href="https://www.asthmaandlung.org.uk/" target="_blank" rel="noreferrer noopener">Asthma + Lung UK</a>, celebrated the breakthrough but highlighted the long delay in innovation.&nbsp;</p>



<p>“It's appalling that this is the first new treatment for those suffering from asthma and COPD attacks in 50 years, indicating how desperately underfunded lung health research is.”</p>



<p>“Every four minutes in the UK, someone dies from a lung condition. Thousands more live with the terror of struggling to breathe every day,” she added.</p>



<h2 class="wp-block-heading" id="h-the-future-of-asthma-treatment">The future of asthma treatment</h2>



<p>The ABRA trial's success highlights the importance of collaboration between universities and healthcare systems.&nbsp;</p>



<p>“The ABRA trial was only possible with collaboration between the NHS and universities and shows how this close relationship can innovate health care and improve people's lives,” said lead author Sanjay Ramakrishnan, a clinical research fellow at the <a href="https://www.uwa.edu.au/" target="_blank" rel="noreferrer noopener">University of Western Australia</a> and the <a href="https://www.ox.ac.uk/" target="_blank" rel="noreferrer noopener">University of Oxford</a>.</p>



<p>As researchers continue to explore benralizumab's potential, the hope is that it will transform how asthma and COPD exacerbations are managed globally.&nbsp;</p>



<p>“We hope these pivotal studies will change how asthma and COPD exacerbations are treated for the future, ultimately improving the health for over a billion people living with asthma and COPD across the world,” Bafadhel concluded.</p>

First new asthma treatment in 50 years offers hope for millions

A breakthrough clinical trial has revealed that an injection given...

<p>The development of a big brain in humans and its connection to social bonding has been a hot topic of debate, and secrets found in fossil teeth may hold the answers.</p>



<p>Researchers have been studying the fossilized teeth of an early Homo species from Georgia, dating back approximately 1.77 million years.</p>



<p>The findings suggest that despite having a small brain and reaching adulthood at a similar pace to great apes, these early humans had a prolonged childhood. </p>



<p>This could mean that the large brain of modern humans resulted from an extended childhood along with cultural transmission across generations instead of vice versa.</p>



<h2 class="wp-block-heading" id="h-long-childhood-big-brains">Long childhood, big brains</h2>



<p>A team of scientists has challenged the theory that the long and extended childhoods of modern humans is directly linked to their large brains.</p>



<p>The team, which included specialists from Switzerland's <a href="https://www.uzh.ch/en.html" target="_blank" rel="noreferrer noopener">University of Zurich</a>, the <a href="https://www.esrf.fr/home.html" target="_blank" rel="noreferrer noopener">European Synchrotron Radiation Facility</a> and Georgia's National Museum, analyzed dental development in an early Homo species that was almost an adult. </p>



<p>The results suggest that though these early humans reached adulthood at a similar age as <a href="https://www.earth.com/news/buronius-manfredschmidi-tiny-great-ape-species-lived-11-million-years-ago/" target="_blank" rel="noreferrer noopener">great apes</a>, their tooth development followed a longer timeline similar to modern humans.</p>



<p>This proposes the distinct possibility of a longer dependency on adults and an elongated childhood for these early humans.</p>



<p>Remarkably, the brain size of these early Homo specimens was only marginally larger than that of a chimpanzee. </p>



<h2 class="wp-block-heading" id="h-what-makes-longer-childhoods-better">What makes longer childhoods better?</h2>



<p>This made the researchers question the link between the prolonged development and cultural transmission across generations. Having a longer childhood gives species a prime opportunity to learn essential survival skills. </p>



<p>During these extended early years, young individuals can observe and mimic the behaviors of adults, picking up everything from foraging and hunting techniques to recognizing dangers in their environment. </p>



<p>This hands-on learning ensures that when they’re fully grown, they’re well-equipped to handle the challenges of their habitat. It’s like having extra time to go to school, but for life skills instead of math and history.</p>



<p>Additionally, longer childhoods foster stronger social bonds and cooperation within a group. These strong social connections can lead to better teamwork when it comes to tasks like hunting, building shelters, or protecting the group from threats. </p>



<p>Moreover, the extended period of dependency helps ensure that knowledge and traditions are passed down accurately from one generation to the next. </p>



<p>Eventually, this led to the development of larger brains and longer life spans, traits characteristic of modern humans.</p>



<h2 class="wp-block-heading" id="h-dental-development-in-early-homo">Dental development in early Homo</h2>



<p>An enduring assumption has been that humans' extended growth period is a consequence of <a href="https://www.earth.com/news/our-brain-sizes-are-growing-possibly-lowering-dementia-risk/" target="_blank" rel="noreferrer noopener">increased brain volume</a> since a larger organ requires more energy resources to grow. </p>



<p>But analysis of the fossil's dental growth has caused researchers to question this hypothesis.</p>



<p>The research team used synchrotron imaging to study the dental development of a near-adult fossil of early <em>Homo</em> from the Dmanisi site in Georgia, dated to around 1.77 million years ago. </p>



<div class="wp-block-sendtonews-playerselector">[sendtonews key="CWxiqQg039-4024544-12187" type="single"]</div>



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



<h2 class="wp-block-heading" id="h-big-brains-connection-to-teeth">Big brains' connection to teeth</h2>



<p>“Dental development is strongly correlated with the development of the rest of the body, including brain development," explained study co-author Paul Tafforeau, scientist at the ESRF.</p>



<p>"Access to the details of a <a href="https://www.earth.com/search-results/?search=fossil%20hominid&amp;start=0" target="_blank" rel="noreferrer noopener">fossil</a> hominid's dental growth therefore provides a great deal of information about its general growth."</p>



<p>After almost two decades of research beginning in 2005, the initial results startled researchers. </p>



<p>“We expected to find either dental development typical of early hominids, close to that of the great apes, or dental development close to that of <a href="https://www.earth.com/news/neanderthal-genes-still-influence-modern-humans/" target="_blank" rel="noreferrer noopener">modern humans</a>," said Tafforeau.</p>



<p>"When we obtained the first results, we couldn’t believe what we saw, because it was something different that implied faster molar crown growth than in any other fossil hominin or living great ape."</p>



<h2 class="wp-block-heading" id="h-follow-up-experiments">Follow-up experiments</h2>



<p>In the following years, the team conducted five series of experiments and completed four full analyses, employing various methods as dental synchrotron imaging technology advanced.</p>



<p>As the consistent results suggested significant implications for the "big brain - long childhood" hypothesis, the scientists needed to think creatively to interpret this fossil's findings.</p>



<p>“It's been a slow maturation, both technically and intellectually, to finally arrive at the hypothesis we are publishing today,” said Tafforeau.</p>



<h2 class="wp-block-heading" id="h-passing-culture-through-generations">Passing culture through generations</h2>



<p>The dental development of the studied fossil suggested that milk teeth were used longer than in great apes, implying that early Homo children were dependent on adult care for a longer duration.</p>



<p>This could be the first experiment evolution took towards a prolonged childhood. Despite having brains only slightly larger than australopithecines or great apes, early Homo are believed to have lived longer.</p>



<p>The survival of a very old individual with no teeth for several years indicates that the group sufficiently cared for him. This alludes to a three-generation structure, a key aspect of <a href="https://www.earth.com/news/humans-started-cumulative-culture-around-600000-years-ago/" target="_blank" rel="noreferrer noopener">cultural transmission in humans</a>.</p>



<p>The new hypothesis begins with children's growth slowing down as cultural transmission increased. </p>



<p>The accumulation of information from older to younger individuals had an advantageous effect on resource utilization and the development of complex behaviors, thus favoring a longer childhood. </p>



<p>Once this mechanism was established, natural selection acted on cultural transmission, not just biological traits. </p>



<h2 class="wp-block-heading" id="h-big-brains-and-delayed-adulthood">Big brains and delayed adulthood</h2>



<p>As the volume of transferrable information grew, evolution supported a larger brain and delayed adulthood, enabling a longer learning period in childhood and time to grow a bigger brain despite limited food resources.</p>



<p>The large brain of modern humans could be attributed to an extended childhood and a three-generation structure encouraging bio-cultural evolution. </p>



<p>These mechanisms may have led to increased brain size, delayed adulthood, and longer lifespan.</p>



<p>The study of this exceptional fossil could motivate researchers to rethink the evolutionary mechanisms that led to Homo sapiens.</p>

<p>The human body excels at maintaining internal balance in a process known as homeostasis. This vital mechanism keeps our core temperature steady at 37°C, regardless of external conditions. </p>



<p>But now, breakthrough research from the Ikmi Group at EMBL Heidelberg reveals that homeostasis goes beyond internal regulation - it can actively redefine an organism’s shape.</p>



<p>The starlet sea anemone (<em>Nematostella vectensis</em>) provides a stunning example of this phenomenon. Renowned for its extraordinary regenerative abilities, this <a href="https://www.earth.com/news/sea-anemones-use-their-shyness-survive-heatwaves/" target="_blank" rel="noreferrer noopener">creature</a> can regrow a lost head or foot and even rebuild a complete, functional body from a sliced fragment.&nbsp;</p>



<p>But unlike many regenerating animals that restore parts in proportion to what remains, the sea anemone reshapes its entire body to preserve its overall form, even adjusting undamaged areas.</p>



<h2 class="wp-block-heading" id="h-regeneration-in-sea-anemones">Regeneration in sea anemones<br></h2>



<p>“<a href="https://www.earth.com/news/axolotls-regeneration-powers-critically-endangered/" target="_blank" rel="noreferrer noopener">Regeneration</a> is about restoring function after tissue loss or damage,” explained Aissam Ikmi, <a href="https://www.embl.org/sites/heidelberg/" target="_blank" rel="noreferrer noopener">EMBL Heidelberg</a> Group Leader and senior author of a new study published in the journal <a href="http://dx.doi.org/10.1016/j.devcel.2024.11.001" target="_blank" rel="noreferrer noopener"><em>Developmental Cell</em></a>.&nbsp;</p>



<p>“Most research studies mainly consider patterns and sizes in regeneration, but our findings show that maintaining shape is also crucial - and it’s something the organism actively controls.”</p>



<p>The discovery started when Stephanie Cheung, a doctoral researcher in Ikmi’s group, noticed an unexpected phenomenon: when a sea anemone’s foot was injured, cell division occurred not only at the wound site but also at the opposite end of the body near the mouth. This hinted at signals being sent across the entire organism in response to injury.</p>



<h2 class="wp-block-heading" id="h-molecular-changes-triggered-by-injury">Molecular changes triggered by injury</h2>



<p>Using spatial transcriptomics and advanced imaging techniques, the research team mapped gene activity across the anemone’s body during regeneration.&nbsp;</p>



<p>They found that injury triggered molecular changes both near and far from the wound. Cells moved, tissues reorganized, and the entire body reshaped itself to maintain its original proportions.</p>



<p>The extent of this reshaping depended on the severity of the injury. Losing a foot caused mild adjustments, while being cut in half led to significant remodeling.&nbsp;</p>



<p>A key player in this process was a family of enzymes called metalloproteases, which became more active as more tissue was lost. These enzymes helped realign tissues, not just at the wound site but throughout the body.</p>



<p>“Metalloprotease activity has never been shown before in animals like this,” said Petrus Steenbergen, one of the study’s lead authors and an Ikmi Group Senior Research Technician.&nbsp;</p>



<p>“I had to design and optimize experimental conditions for <em>Nematostella</em> based on the sparse literature available from other species. This took some time, but the final results were very rewarding.”</p>



<h2 class="wp-block-heading" id="h-sea-anemones-restore-their-shapes">Sea anemones restore their shapes</h2>



<p>The team discovered that the sea anemone prioritizes restoring its shape, even after significant injury.&nbsp;</p>



<p>By measuring the aspect ratio - the ratio of length to width - they found that the anemone consistently returned to its pre-injury proportions. This proportional response allowed the organism to maintain its shape, even if it became smaller.</p>



<p>“We were able to witness the body-wide coordination that drives this remodeling,” Ikmi explained. “This proportional response allows the anemone to restore its shape, highlighting how organisms like <em>Nematostella</em> interpret and respond to tissue loss in a way that’s scaled to the damage incurred.”</p>



<h2 class="wp-block-heading" id="h-collaborative-efforts-and-advanced-techniques">Collaborative efforts and advanced techniques</h2>



<p>The study was a collaborative endeavor. Rik Korswagen’s team at the <a href="https://www.hubrecht.eu/" target="_blank" rel="noreferrer noopener">Hubrecht Institute</a> in the Netherlands helped implement spatial transcriptomics in the sea anemone.&nbsp;</p>



<p>Additionally, Oliver Stegle’s team at EMBL Heidelberg and the <a href="https://www.dkfz.de/en/index.html" target="_blank" rel="noreferrer noopener">German Cancer Research Center</a> (DKFZ) provided bioinformatics expertise and statistical methods to analyze spatial <a href="https://www.earth.com/news/personality-has-a-profound-influence-on-gene-expression/" target="_blank" rel="noreferrer noopener">gene expression</a> data.</p>



<p>“It was a pleasure to puzzle out the findings of the study together by uniting the team’s expertise in data analysis and cell biology,” said Tobias Gerber, another of the study’s lead authors. “This work was a truly collaborative journey, and I am glad I was part of it.”</p>



<h2 class="wp-block-heading" id="h-questions-remain-about-sea-anemone-regeneration-nbsp">Questions remain about sea anemone regeneration&nbsp;</h2>



<p>While the research offers fascinating insights into how <em>Nematostella</em> maintains its shape during regeneration, it raises new questions.</p>



<p>“The next big question is why maintaining shape is so important,” Ikmi said. “And how does the organism sense its own shape? How does it know what it currently looks like?”</p>



<p>With the starlet sea anemone as their model, the team is eager to explore the mechanisms underlying these abilities. Their work holds promise for understanding how organisms heal, maintain balance, and adapt to injury, potentially unlocking new avenues in <a href="https://www.earth.com/news/secrets-of-killifish-regeneration-may-help-us-heal-humans/" target="_blank" rel="noreferrer noopener">regenerative medicine</a> and biology.</p>

<p>The unending stretch of the Greenland Ice Sheet, like a seasoned custodian of countless secrets, has concealed a Cold War-era ice camp beneath its surface.</p>



<p>This hidden camp came to light in 2024 when NASA scientist Chad Greene, aboard the Gulfstream III with his team of engineers, embarked on the expedition of a lifetime.</p>



<p>While probing the depths of the ice sheet about 150 miles east of Pituffik Space Base in northern Greenland, the radar readings showed a <a href="https://www.earth.com/wp-content/uploads/2024/11/greenland_camp-century_hidden-base_buried-under-ice_NASA_1m.jpg" target="_blank" rel="noreferrer noopener">curious blip that sparked their interest</a>.</p>

<h2 class="wp-block-heading" id="h-camp-century-city-under-the-ice">Camp Century: City under the ice</h2>



<p>"We were looking for the bed of the&nbsp;ice, and out pops&nbsp;Camp&nbsp;Century," exclaimed Alex Gardner, a cryospheric scientist at NASA's Jet Propulsion Laboratory (<a href="https://www.jpl.nasa.gov" target="_blank" rel="noreferrer noopener">JPL</a>), who had assisted in spearheading the project.</p>



<p>Camp Century, also affectionately known as the "city under the ice," is a vestige of the chilling days when the Cold War was in full swing. </p>



<p>Constructed in 1959 by the U.S. Army Corps of Engineers, this hidden military base was etched out within the layers of the <a href="https://www.earth.com/news/greenland-ice-sheet-discovery-transforms-sea-level-predictions/" target="_blank" rel="noreferrer noopener">ice sheet</a> itself.</p>



<p>Traces of the facility, which has been abandoned since 1967, now lie encased approximately 30 meters (100 feet) beneath the icy surface, waiting to narrate their intriguing past.</p>



<h2 class="wp-block-heading" id="h-what-exactly-went-on-at-camp-century">What exactly went on at Camp Century?</h2>



<p>Camp Century's main goal was to explore the feasibility of living and operating in extreme cold conditions, which was crucial during the Cold War era. </p>



<p>The base was constructed using large, <a href="https://eoimages.gsfc.nasa.gov/images/imagerecords/153000/153616/campcentury_pho_1966_lrg.jpg" target="_blank" rel="noreferrer noopener">prefabricated modules connected by tunnels</a>, all insulated and heated to keep the inhabitants comfortable despite the freezing temperatures outside. </p>



<p>About 25 scientists and military personnel lived there, conducting experiments in geology, hydrology, and glaciology, while also testing technologies that could support long-term Arctic missions.</p>



<p>One of the most intriguing aspects of Camp Century is its innovative use of nuclear power. </p>



<p>The base was powered by a portable nuclear reactor, making it one of the first of its kind to operate in such harsh environments. </p>



<p>However, when the base was abandoned in 1967, concerns arose about the disposal of nuclear waste left behind.</p>



<h2 class="wp-block-heading" id="h-deciphering-the-indicators">Deciphering the indicators</h2>



<p>Akin to an ultrasound meant for ice sheets, radar plays a pivotal role in unraveling the truths kept secret by nature.</p>



<p>Radar works on a simple principle - it emits radio waves and times their reflections back to the source. This allows scientists to map out the ice surface meticulously, along with its various internal layers, and the bedrock underneath.</p>



<p>Previous airborne surveys that flew over Camp Century managed to detect signs of the base encapsulated within the ice sheets. </p>



<p>These surveys utilized conventional, ground-penetrating radar that aims directly downwards, which yielded a 2D profile of the ice sheet. </p>



<p>This gave an impression of Camp Century's solid structures that appeared like an anomaly in the deformed layers of ice.</p>



<h2 class="wp-block-heading" id="h-generating-maps-with-advanced-technology">Generating maps with advanced technology </h2>



<p>The April 2024 flights, however, could go a step further with NASA's <a href="https://uavsar.jpl.nasa.gov" target="_blank" rel="noreferrer noopener">UAVSAR</a> (Uninhabited Aerial Vehicle Synthetic Aperture Radar) adorning the belly of the aircraft.</p>



<p>This cutting-edge system introduces a wider angle of view, and looks both downward and sideways, thus generating maps that teem with additional dimensions.</p>



<p>"In the new data, individual structures in the secret city are visible in a way that they've never been seen before," explained Greene.</p>



<h2 class="wp-block-heading" id="h-determining-the-camp-s-alignment-under-ice">Determining the camp's alignment under ice</h2>



<p>When juxtaposed with historical maps of the base's planned layout, the parallel structures demonstrate a striking alignment with the tunnels initially built to house a myriad of facilities.</p>



<p>Yet, the added dimensionality comes with its own challenges in terms of interpretation. </p>



<p>For instance, the long line that seems to appear "above" the base is actually the ice bed, lying at least a mile below the ice sheet's surface, and well beneath the depth of Camp Century.</p>



<p>This apparent "inversion" is caused by the radar's return showing part of the <a href="https://www.earth.com/news/satellite-records-a-650-foot-tsunami-in-greenland-that-lasted-9-days/" target="_blank" rel="noreferrer noopener">ice</a> bed far in the distance.</p>



<h2 class="wp-block-heading" id="h-camp-century-more-than-a-historical-curiosity">Camp Century: More than a historical curiosity</h2>



<p>Apart from their historical significance, maps created with conventional radar have aided scientists in corroborating estimates of Camp Century's depth.</p>



<p>This information is crucial in estimating when the melting and thinning of the ice sheet could potentially re-expose the camp and any leftover biological, chemical, and radioactive waste buried with it.</p>



<p>The scientific utility of the new UAVSAR image of Camp Century remains uncertain. For the moment, it's a novelty - an amazing discovery made purely by chance. However, the principal aim of Greene and Gardner was not to capture this image of Camp Century.</p>



<p>Their principal objective was to "calibrate, validate, and understand the capabilities and limitations of UAVSAR for mapping the ice sheet's internal layers and the ice-bed interface," as Greene clarified.</p>



<h2 class="wp-block-heading" id="h-the-future-of-measuring-ice-thickness">The future of measuring ice thickness</h2>



<p>Such instruments hold the key to a future where scientists might efficiently measure the thickness of ice sheets in similar <a href="https://www.earth.com/news/greenland-transformation-ice-melt-plant-growth-vegetation-cascading-effects/" target="_blank" rel="noreferrer noopener">environments</a> in Antarctica. Such data is critical in modeling estimates of future sea level rise.</p>



<p>"Without a detailed knowledge of ice thickness, it is impossible to know how the ice sheets will respond to rapidly warming oceans and atmosphere, greatly limiting our ability to project rates of sea level rise," Gardner explained.</p>



<p>The test flights that captured Camp Century will undoubtedly usher in the next generation of mapping campaigns focused on ice in Greenland, Antarctica, and beyond.</p>

"City under the ice": NASA finds secret base buried in Greenland

The unending stretch of the Greenland Ice Sheet, like a...

<p>With over 30,000 weather stations worldwide collecting daily data on temperature, precipitation, and other climate indicators, analyzing this immense dataset is a monumental task for researchers.&nbsp;</p>



<p>Traditionally, climate scientists have relied on statistical methods to interpret these datasets, but a recent breakthrough demonstrates the power of artificial intelligence (AI) to revolutionize this process.</p>



<h2 class="wp-block-heading" id="h-previously-unrecorded-climate-extremes">Previously unrecorded climate extremes</h2>



<p>A team led by Étienne Plésiat of the <a href="https://www.dkrz.de/en/dkrz-partner-for-climate-research?set_language=en" target="_blank" rel="noreferrer noopener">German Climate Computing Center</a> in Hamburg, alongside colleagues from the UK and Spain, applied AI to reconstruct European climate extremes.</p>



<p>The research not only confirmed known climate trends but also revealed previously unrecorded extreme <a href="https://www.earth.com/news/climate-change-earth-energy-imbalance-temperature-rise/" target="_blank" rel="noreferrer noopener">events</a>.</p>



<p>As climate change accelerates, understanding how temperature and precipitation extremes are evolving is critical for adaptation and planning.&nbsp;</p>



<p>Recent studies have shown that heat and <a href="https://www.earth.com/news/rainfall-is-increasingly-unpredictable-due-to-climate-change/" target="_blank" rel="noreferrer noopener">rainfall</a> extremes are increasing dramatically. For instance, heavy rainfall events in some regions are now classified as “far outside the historical climate,” while heat extremes have expanded, affecting over 30% of global land areas annually compared to just 1% in 1950.</p>



<h2 class="wp-block-heading" id="h-ai-offers-a-solution-to-data-gaps">AI offers a solution to data gaps</h2>



<p>Despite the increasing prevalence of climate extremes, analyzing historical temperature data is challenging due to gaps in records. </p>



<p>Weather stations - particularly in the early 20th century - often faced interruptions, whether due to damaged equipment, station closures, or the lack of replacements.&nbsp;</p>



<p>Sparse data from regions like Africa and the polar areas further complicate comprehensive analysis.</p>



<p>Data homogenization, a research area focused on standardizing and filling gaps in datasets, has long been used to address these issues.&nbsp;</p>



<p>However, traditional statistical methods often struggle in areas with scarce weather stations, leaving uncertainties in extreme climate reconstructions.</p>



<p>Recognizing the limitations of traditional methods, Plésiat and his colleagues turned to <a href="https://www.earth.com/news/ai-predicts-global-warmings-impact-on-extreme-weather/" target="_blank" rel="noreferrer noopener">AI</a>, specifically neural network techniques, to reconstruct temperature extremes.&nbsp;</p>



<h2 class="wp-block-heading" id="h-climate-extremes-in-europe-nbsp">Climate extremes in Europe&nbsp;</h2>



<p>Europe, with its dense network of weather stations and long historical records - such as the Hadley Central England Temperature dataset, which dates back to 1659 - offered an ideal testing ground.</p>



<p>The team’s AI, dubbed CRAI (Climate Reconstruction AI), focused on extreme events such as unusually warm or cold days and nights. </p>



<p>CRAI outperformed traditional interpolation methods like Kriging and Inverse Distance Weighting, which predict temperatures at unmeasured locations using nearby weather station data.&nbsp;</p>



<p>These traditional methods often falter when station density is low, a gap that CRAI bridged effectively.</p>



<h2 class="wp-block-heading" id="h-reconstructing-climate-history">Reconstructing climate history</h2>



<p>Using historical simulations from the CMIP6 archive (Coupled Model Intercomparison Project), the team trained CRAI to reconstruct past climate data.&nbsp;</p>



<p>The experts validated their results using standard metrics such as root mean square error and Spearman’s rank-order correlation coefficient, which measure accuracy and association between variables.</p>



<p>The results were promising. CRAI outperformed conventional methods in reconstructing the frequency of extreme events—such as the percentage of days with temperatures above the 90th percentile (warm days) or below the 10th percentile (cool days).</p>



<p>The researchers then applied CRAI to the HadEX3 dataset, which includes over 80 indices of extreme temperature and precipitation from 1901 to 2018. CRAI not only reconstructed past extremes with high accuracy but also uncovered long-forgotten events.</p>



<h2 class="wp-block-heading" id="h-unearthing-unknown-climate-extremes">Unearthing unknown climate extremes</h2>



<p>One of the most striking findings was CRAI’s ability to reveal previously unrecorded climate extremes. For instance, the AI uncovered a severe cold spell in 1929 and a major <a href="https://www.earth.com/news/marine-heatwaves-are-expanding-their-reach-across-the-globe/" target="_blank" rel="noreferrer noopener">heatwave</a> in 1911, events that were only hinted at anecdotally due to sparse data at the time.</p>



<p>“Our research demonstrates both the necessity and the potential benefits of applying this approach to the global scale or other regions with scarce data,” the authors explained.&nbsp;</p>



<p>They emphasized that AI-based reconstruction enhances accuracy, particularly in data-poor regions, and opens new possibilities for climate research.</p>



<h2 class="wp-block-heading" id="h-the-potential-of-ai-in-climate-science">The potential of AI in climate science</h2>



<p>The study highlights AI’s transformative potential to improve our understanding of climate extremes and their long-term changes.&nbsp;</p>



<p>By training models like CRAI on larger datasets, researchers can achieve even greater accuracy and uncover hidden patterns in global climate history.</p>



<p>“This work underscores the transformative potential of AI to improve our understanding of climate extremes and their long-term changes,” the researchers concluded.</p>



<p>As climate change continues to intensify, AI tools like CRAI offer a powerful means to analyze past data, predict future trends, and guide adaptation strategies in an increasingly extreme world.</p>



<p>The study is published in the journal <em><a href="https://www.nature.com/articles/s41467-024-53464-2" target="_blank" rel="noreferrer noopener">Nature Communications</a></em>.</p>

AI reveals hidden climate extremes in Europe

With over 30,000 weather stations worldwide collecting daily data on...

<p>Light is something we interact with every day, but have you ever wondered what the shape of a single particle of light -- the photon -- actually looks like? </p>



<p>For the first time, researchers have defined the <a href="https://www.earth.com/wp-content/uploads/2024/11/photon-single_precise-shape_credit-Benjamin-Yuen_1m.jpg" target="_blank" rel="noreferrer noopener">precise shape</a> of a single photon, a huge leap forward in quantum physics and material science.</p>



<p>Dr. Benjamin Yuen from the <a href="https://www.birmingham.ac.uk/" target="_blank" rel="noreferrer noopener">University of Birmingham</a> led the groundbreaking research that delves deep into the quantum level of light and matter interaction. </p>



<p>His team's findings, published in <em>Physical Review Letters</em>, provide a visual representation of a photon while enhancing our understanding of how photons are emitted and shaped by their environment.</p>



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



<p>A photon is the fundamental unit of light and all <a href="https://www.earth.com/news/lightning-sparks-the-discovery-of-a-new-electromagnetic-wave/" target="_blank" rel="noreferrer noopener">electromagnetic radiation</a>. Unlike particles that have mass, photons are massless and always move at the speed of light.</p>



<p>They exhibit both particle-like and wave-like properties, a concept known as <a href="https://www.earth.com/news/quantum-tunneling-allow-particles-break-light-speed-barrier/" target="_blank" rel="noreferrer noopener">wave-particle duality</a>.</p>



<p>Photons carry energy and momentum, determined by their frequency or wavelength. Simply put, the higher the frequency, the more energy a photon possesses. </p>



<p>This unique dual nature allows photons to interact with matter in special ways, such as being absorbed or emitted by atoms. </p>



<p>These interactions are essential for processes like vision, <a href="https://www.earth.com/news/key-to-life-on-earth-photosynthesis-begins-on-the-quantum-level-with-a-single-photon/" target="_blank" rel="noreferrer noopener">photosynthesis</a>, and the technology behind our electronic devices.</p>



<h2 class="wp-block-heading" id="h-photon-shape-and-the-far-field">Photon shape and the "far field"</h2>



<p>The interaction between photons and their environment leads to endless possibilities for how light exists and travels. </p>



<p>This limitless potential makes modeling these interactions exceptionally challenging -- a puzzle that quantum physicists have been trying to solve for decades.</p>



<p>"Our calculations enabled us to convert a seemingly unsolvable problem into something that can be computed," Dr. Yuen explained.</p>



<p>"And, almost as a byproduct of the model, we were able to produce this image of a photon, something that hasn't been seen before in physics."</p>



<p>By grouping the infinite possibilities of photon interactions into distinct sets, the team produced a model that describes not only <a href="https://www.earth.com/news/quantum-leap-making-light-waves-stand-still-photonic-crystals/" target="_blank" rel="noreferrer noopener">how photons interact </a>with the atoms or molecules that emit them, but also how the energy from that interaction travels into the distant surroundings, known as the "far field."</p>



<h2 class="wp-block-heading" id="h-why-do-we-care-about-photon-shape">Why do we care about photon shape?</h2>



<p>We depend on photons more than we might realize. Our eyes detect photons, allowing us to see the world around us. </p>



<p>In technology, photons are crucial for solar panels that convert light into electricity and fiber optic cables that provide high-speed <a href="https://www.earth.com/news/artificial-atoms-qkd-quantum-communication-revolutionizing-data-protection-privacy/" target="_blank" rel="noreferrer noopener">internet and communications</a>.</p>



<p>Photons also play a significant role in scientific research. They are central to <a href="https://www.earth.com/news/like-charged-particles-attract-each-other-defying-coulombs-laws-of-physics/" target="_blank" rel="noreferrer noopener">quantum electrodynamics</a> (QED), the theory that describes how light and matter interact. </p>



<p>Photons act as force carriers for the electromagnetic force, one of the four fundamental forces in the universe. </p>



<p>They facilitate interactions between charged particles like electrons and protons, governing a wide range of physical phenomena.</p>



<h2 class="wp-block-heading" id="h-advancing-quantum-physics">Advancing quantum physics</h2>



<p>"The geometry and optical properties of the environment have profound consequences for how photons are emitted, including defining the photons' shape, color, and even how likely it is to exist," explained co-author Professor Angela Demetriadou.</p>



<p>Understanding the precise shape and behavior of photons could revolutionize the way we design <a href="https://www.earth.com/news/trapped-atoms-forced-to-serve-as-transistors-quantum-network/" target="_blank" rel="noreferrer noopener">nanophotonic technologies</a>. </p>



<p>This could lead to advancements in <a href="https://www.earth.com/news/unbreakable-encryption-brings-quantum-internet-communication-closer-to-reality/" target="_blank" rel="noreferrer noopener">secure communication methods</a>, improved detection of pathogens, and even control over chemical reactions at a molecular level.</p>



<p>"This work helps us to increase our understanding of the energy exchange between light and matter, and to better understand how light radiates into its nearby and distant surroundings," Dr. Yuen added.</p>



<p>"Lots of this information had previously been thought of as just 'noise' -- but there's so much information within it that we can now make sense of and make use of."</p>



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



<p>By comprehending how photons interact with their environment, scientists can engineer <a href="https://www.earth.com/news/if-shadows-are-created-by-light-how-can-laser-light-cast-a-shadow/" target="_blank" rel="noreferrer noopener">light-matter interactions</a> for future applications. </p>



<p>Imagine better sensors that can detect diseases at an early stage, more efficient solar cells that provide cleaner energy, or advancements in quantum computing that could solve complex problems in seconds.</p>



<p>"By understanding this, we set the foundations to be able to engineer <a href="https://www.earth.com/news/quantum-ping-pong-game-played-by-two-atoms-controlling-photons/" target="_blank" rel="noreferrer noopener">light-matter interactions</a> for future applications," says Dr. Yuen. </p>



<p>The possibilities are vast and could significantly impact various fields, from healthcare to technology and environmental science.</p>



<h2 class="wp-block-heading" id="h-photon-shape-and-future-technology">Photon shape and future technology</h2>



<p>To sum it all up, this fascinating research represents a significant step forward in quantum physics. </p>



<p>By defining the precise shape of a single photon, the team has provided a tool that could help scientists and engineers design new technologies that harness the unique properties of light.</p>



<p>The findings not only answer long-standing questions about the fundamental nature of photons but also open up new questions and research paths. </p>



<p>As we continue to explore the <a href="https://www.earth.com/news/how-quantum-revolution-will-impact-all-aspects-of-society/" target="_blank" rel="noreferrer noopener">quantum world</a>, understanding the building blocks of light will be crucial in pushing the boundaries of what's possible.</p>



<p>The visualization of a photon is a testament to human curiosity and our desire to understand the universe at its most fundamental level. </p>



<p>With this new knowledge, we're not just looking at light differently -- we're poised to use it in ways we never thought possible.</p>



<p>The full study was published in the journal <em><a href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.133.203604" target="_blank" rel="noreferrer noopener">Physical Review Letters</a></em>.</p>

Exact shape of a single photon revealed for the first time

Light is something we interact with every day, but have...

<p>For Neanderthals, the most advanced technology wasn't necessarily metal or stone; it could have been a simple piece of sticky plant matter.</p>



<p>This remarkable adhesive, used to bind tools or even chewed for health benefits, played a crucial role in  daily life.</p>



<p>While it's long been known that Neanderthals relied on birch tar, the mystery of how they extracted and processed this valuable substance has remained unsolved - until now.</p>



<h2 class="wp-block-heading" id="h-the-forgotten-neanderthal-pit">The forgotten Neanderthal pit</h2>



<p>A remarkable study involving researchers from the <a href="https://ics-seville.org/university-of-seville/" target="_blank" rel="noreferrer noopener">University of Seville</a> has offered the answers we've been looking for.</p>



<p>Inside the Vanguard Cave in Gibraltar, researchers unearthed a structure that aligns with theories about how the Neanderthals could have obtained the resinous tar from processing different plants.</p>



<p>The humble structure appears to be a simple pit, but it has monumental implications as a presumed anoxic heating chamber. Its simplicity meant that the pit's potential significance was overlooked.</p>



<p>However, this structure's discovery in a UNESCO World Heritage Site, known as Gorham’s Caves Complex, is foundational in our understanding of <a href="https://www.earth.com/news/early-humans-impacted-earth-than-previously-thought-2/" target="_blank" rel="noreferrer noopener">ancient human activities</a>.</p>



<p>The site's preservation is due to its swift encapsulation by a dune.</p>



<h2 class="wp-block-heading" id="h-exceptional-cognitive-abilities-of-neanderthals">Exceptional cognitive abilities of Neanderthals </h2>



<p>The discovery was not a one-man job. A team of 31 researchers, hailing from more than five countries and specializing in 15 different fields, collaborated to establish that this structure indeed dates back 60,000 years to Neanderthal times.</p>



<p>The University of Seville's own Fernando Muñiz clarifies that Neanderthals were not, as often depicted, crude and brutal beings.</p>



<p>In fact, the discovery reaffirms that they demonstrated <a href="https://www.earth.com/news/neanderthal-behavior-provides-clues-about-their-extinction/" target="_blank" rel="noreferrer noopener">exceptional cognitive abilities</a> as they were able to use chemical processes to create a resinous adhesive for their tools.</p>



<h2 class="wp-block-heading" id="h-how-smart-were-neanderthals">How smart were Neanderthals?</h2>



<p>Neanderthals were smarter than many people give them credit for. They crafted sophisticated tools using the Mousterian technique, which shows they could plan and execute complex tasks. </p>



<p>These early humans hunted large game together, suggesting they worked well in teams and communicated effectively. </p>



<p>They also managed to control fire, build sturdy shelters, and make clothing from animal hides, which kept them warm in harsh climates. All these activities point to strong problem-solving skills and adaptability.</p>



<p>Beyond their practical skills, Neanderthals showed signs of creativity and social complexity. They buried their dead, which might indicate a sense of ritual or respect for others. </p>



<p>Some archaeological finds suggest they created art or decorative items, hinting at symbolic thinking. Their brains were as large as or even larger than ours, which likely gave them the capacity for language and complex thought. </p>



<h2 class="wp-block-heading" id="h-neanderthals-were-masters-of-technology">Neanderthals were masters of technology</h2>



<p>According to Clive Finlayson, the excavation manager, creating this adhesive substance would have required a thoughtful process. This includes selecting the appropriate plants and extracting the resin without incinerating them.</p>



<p>To validate that the Neanderthals constructed the structure, the team developed methodologies and even completed an archaeological exercise. </p>



<p>Evidence also suggests that the adhesive resin may have been extracted from the prickly <a href="https://www.earth.com/news/how-do-plants-handle-competition-during-extreme-drought/" target="_blank" rel="noreferrer noopener">rockrose plant</a>, a tree that was more prevalent in Mediterranean latitudes during Neanderthal times.</p>



<p>This transformative project sets a precedent in understanding the technological prowess and organizational capacity of the Neanderthals.</p>



<p>Led by the Gibraltar Museum, the University of Murcia, the Andalusian Earth Sciences Institute, and with contributions from the University of Seville, the project is shedding new light on <a href="https://www.earth.com/news/study-provides-insights-into-the-lives-of-neanderthals/" target="_blank" rel="noreferrer noopener">Neanderthal life</a>.</p>



<h2 class="wp-block-heading" id="h-uncovering-evidence-of-early-artistry">Uncovering evidence of early artistry</h2>



<p>Finlayson's team also discovered a unique hashtag-like mark on a piece of limestone in 2012. This simple yet significant engraving is seen by experts as evidence of early artistry.</p>



<p>Neanderthals also collected feathers - specifically black ones - from a variety of birds, possibly for decorative or ceremonial purposes.</p>



<p>Neanderthals had an understanding of medicinal plants and even buried their dead. Jewelry-making and specialized <a href="https://www.earth.com/news/neanderthals-glue-created-and-used-underestimated-intelligence/" target="_blank" rel="noreferrer noopener">tool creation</a> were also part of their innovation basket.</p>



<p>According to Muñiz, they could communicate vocally and possibly had high-pitched, hoarse voices.</p>



<p>As our understanding of these prehistoric humans deepens, it becomes increasingly clear that there was more to them than meets the eye. Through ingenuity, organization, and craft, they were indeed masters of their primitive world.</p>



<h2 class="wp-block-heading" id="h-an-impressive-legacy-of-innovation">An impressive legacy of innovation</h2>



<p>The discovery of the adhesive-making pit in Gibraltar challenges our modern perception of innovation. </p>



<p>While technology today is often associated with complexity, the Neanderthals demonstrate that simplicity and ingenuity can coexist. </p>



<p>Their ability to adapt natural resources to solve practical problems, like binding tools with resinous extracts, highlights an advanced understanding of materials science and environmental management.</p>



<h2 class="wp-block-heading" id="h-early-form-of-experimental-circumstances">Early form of experimental circumstances </h2>



<p>Beyond practicality, their actions reveal a deeper connection to their environment. By selecting specific plants and mastering controlled heating techniques, Neanderthals showcased an early form of experimental learning that enabled them to refine processes through observation and iteration.</p>



<p>This suggests they not only developed innovative methods but also passed down this knowledge across generations, forming the building blocks of technological heritage.</p>



<p>This discovery also serves as a reminder of the fragility of human history. Structures like the resin pit are rare finds, preserved only under exceptional circumstances. </p>



<p>The swift encapsulation of the site by sand dunes has protected a story that might otherwise have been lost to time. </p>



<p>These ancient innovations, hidden beneath layers of sediment, remind us of the resilience and ingenuity of our distant relatives, and inspire us to look at innovation through a broader, more inclusive lens.</p>

<p>An old saying would have us believe that "age is just a number." But in the context of our organs, aging is not a uniform process. Because of this, doctors often use the term "biological age," which has quickly become the hottest new health and wellness buzzword.</p>



<p>It turns out, your heart might be older than your chronological age, while your brain could be equivalent to that of someone who is much younger.</p>



<h2 class="wp-block-heading" id="h-biological-age-what-does-that-mean">"Biological age" -- what does that mean?</h2>



<p>You'd imagine that, as we age, our body follows suit as a whole. But recent research suggests that it's not so simple. What's happening under the skin is much more complex.</p>



<p>When people refer to "biological age" they're talking about how your <a href="https://www.earth.com/news/human-bodies-undergo-very-rapid-change-aging-at-two-very-specific-times/" target="_blank" rel="noreferrer noopener">body is really aging</a>, which might be different from the number of years you've been alive.</p>



<p>While <a href="https://www.earth.com/news/time-flies-by-much-faster-as-we-get-older-human-perception/" target="_blank" rel="noreferrer noopener">chronological age</a> counts the actual time since you were born, biological age looks at factors like how well your organs are functioning, your muscle strength, and even things like your skin elasticity.</p>



<p>It's influenced by your lifestyle choices, such as diet, exercise, sleep, and stress levels, as well as your genetics.</p>



<h2 class="wp-block-heading" id="h-how-biological-age-correlates-to-health">How biological age correlates to health</h2>



<p>For example, two people who are both 50 years old chronologically might have very different biological ages depending on how they've taken care of their bodies over the years.</p>



<p>Comparing biological age to chronological age gives a more personalized picture of your overall health and aging process.</p>



<p>If your biological age is lower than your chronological age, it usually means you're leading a healthy lifestyle and your body is functioning better than average for your age.</p>



<p>On the flip side, a higher biological age might indicate that you need to make some changes to improve your health and slow down the aging process.</p>



<h2 class="wp-block-heading" id="h-measuring-the-age-of-organs">Measuring the age of organs</h2>



<p>As mentioned, biological age refers to how well a specific organ is functioning. This "functional age" can be dramatically different across all parts of your body.</p>



<p>It's possible for different organs can have different biological or functional ages. </p>



<p>For instance, if a person is a smoker but does not drink alcohol, you can assume that the functional and biological age of that person's lungs is much lower than the biological age of their liver.</p>



<p>So, how do scientists figure out the biological age of your organs? They've developed sophisticated tools known as "aging clocks."</p>



<p>These clocks analyze the levels of protein markers in your blood samples. The protein markers are the tattletales of your organs, and reveal the secrets of their functional age.</p>



<p>By studying these markers, the researchers can figure out if you're a "heart ager" or a "brain ager."</p>



<h2 class="wp-block-heading" id="h-impact-of-premature-aging">Impact of premature aging</h2>



<p>Is your heart punching above its weight, age-wise? If so, this could increase your risk of heart failure by a staggering 250 percent.</p>



<p>And what about the brain? If it's aging faster than it should, <a href="https://www.earth.com/news/alzheimers-disease-attacks-the-brain-in-two-separate-phases/" target="_blank" rel="noreferrer noopener">Alzheimer's disease</a> may become a realistic concern.</p>



<p>These are just a few examples of the profound consequences of premature aging in particular organs.</p>



<p>On the flip side, a youthful brain might potentially mean less risk of dementia, and a longer life.</p>



<h2 class="wp-block-heading" id="h-why-is-biological-age-important">Why is biological age important?</h2>



<p>It turns out that the <a href="https://www.earth.com/news/tricking-cells-into-thinking-they-ate-less-food-can-slow-aging-process/" target="_blank" rel="noreferrer noopener">aging process</a> in our organs is interconnected. If one organ begins to age prematurely, it might send a biochemical postcard that accelerates the aging process in others.</p>



<p>This chain reaction underscores the importance of keeping our organs healthy and "young" for as long as we can.</p>



<p>The findings of these studies offer a glimmer of hope. If we can figure out which organs are aging faster in our bodies, we could potentially slow down the whole process.</p>



<p>Scientists could tailor medical treatments or suggest <a href="https://www.earth.com/news/simple-lifestyle-changes-could-prevent-half-of-all-cancer-deaths/" target="_blank" rel="noreferrer noopener">lifestyle changes</a> specifically suited to support our older organs. The dream is to manage aging, organ by organ.</p>



<h2 class="wp-block-heading" id="h-aging-and-personalized-medicine">Aging and personalized medicine</h2>



<p>Advancements in personalized medicine are paving the way for innovative approaches to tackling organ-specific aging.</p>



<p>By leveraging the insights from <a href="https://www.earth.com/news/human-bodies-begin-breaking-down-very-precise-age/" target="_blank" rel="noreferrer noopener">aging clocks</a> and biomarkers, researchers can design targeted interventions that address the unique needs of each organ.</p>



<p>For instance, a heart exhibiting advanced biological aging may benefit from treatments aimed at reducing arterial stiffness or improving cardiac tissue regeneration.</p>



<p>Meanwhile, therapies focusing on <a href="https://www.earth.com/news/cannabinol-could-be-key-to-preventing-brain-disorders/" target="_blank" rel="noreferrer noopener">neuroprotection</a> could support a prematurely aging brain.</p>



<p>Such precision not only marks a major leap in age management but also allows for preventive measures that are tailored to the individual and reduce the risk of debilitating conditions before they arise.</p>



<p>This personalized approach holds immense promise for fostering healthier and more vibrant aging.</p>



<h2 class="wp-block-heading" id="h-how-to-stay-young">How to stay young</h2>



<p>While breakthroughs in medical science are exhilarating, the importance of lifestyle choices cannot be overstated.</p>



<p>Diet, exercise, sleep, and stress management play pivotal roles in the biological aging of our organs. <a href="https://www.earth.com/news/inaoside-new-antioxidant-discovered-laetiporus-cremeiporus-mushrooms/" target="_blank" rel="noreferrer noopener">Antioxidant-rich foods</a>, for example, combat oxidative stress, which is a major contributor to aging at the cellular level.</p>



<p>Regular physical activity enhances cardiovascular health and encourages neurogenesis, supporting both heart and brain longevity.</p>



<p>Additionally, quality sleep aids cellular repair, while effective stress management reduces the production of harmful hormones that can accelerate aging.</p>



<p>Simply put, the choices we make every day <a href="https://www.earth.com/news/social-aging-what-animals-can-teach-us-about-getting-older/" target="_blank" rel="noreferrer noopener">act as powerful tools</a> in influencing the age of our internal organs. Small improvements in habits can lead to profound results over time.</p>



<h2 class="wp-block-heading" id="h-what-we-learned">What we learned</h2>



<p>To sum it all up, aging isn't the same for every part of your body, even if you’re the same age as someone else. While your heart might show signs of being older, your brain could be functioning like it's much younger. </p>



<p>This difference is what scientists call "biological age," which looks at how well your organs are doing based on things like muscle strength, skin elasticity, and overall organ function. </p>



<p>Unlike your chronological age, which is just the number of years you've lived, your biological age can vary depending on your lifestyle choices, such as your diet, exercise habits, sleep quality, and stress levels, as well as your genetics. </p>



<p>So, two people who are both 50 years old might have very different biological ages if one leads a healthier lifestyle than the other.</p>



<p>Our understanding and perception of aging needs to shift from a broad stroke approach to a more finely focused one.</p>



<p>By concentrating on the distinct aging patterns of our organs, we just might be able to crack the code and halt or even reverse the aging process.</p>

Which is more important - 'biological age' or 'chronological age'?

An old saying would have us believe that "age is...

<p>They say the sea has many secrets, but the intriguing tale of coral adaptation to oceanic temperature changes, amid the impacts of climate change, may not be hidden for much longer.</p>



<p>The stakes are high; without swift curbs on global greenhouse gas emissions, our coral reefs might not keep up with the demands of a warming sea. </p>



<p>This revelation comes courtesy of an international team of scientists who are striving to peer beyond the turbid waters of environmental uncertainty.</p>



<h2 class="wp-block-heading" id="h-coral-bleaching-from-climate-change">Coral bleaching from climate change</h2>



<p>At the lead of this crucial research is Dr. Liam Lachs, an esteemed figure from <a href="https://www.ncl.ac.uk" target="_blank" rel="noreferrer noopener">Newcastle University</a>. With his dedicated team, he has introduced us to a startling possibility. </p>



<p><a href="https://www.earth.com/news/coral-reefs-may-be-more-resilient-than-we-thought/" target="_blank" rel="noreferrer noopener">Coral reefs</a> might weather the heat of our warming oceans, but only if we rally behind the commitments of the Paris Agreement and keep global warming within the reasonable limit of two degrees Celsius.</p>



<p>“The reality is that marine heatwaves are triggering mass coral bleaching mortality events across the world’s shallow tropical reef ecosystems, and the&nbsp;increasing frequency and intensity&nbsp;of these events is set to ramp up under climate change,” explained Dr. Lachs.</p>



<p>While there are ripples of hope from recent studies that suggest the potential for adaptation among corals, one fundamental question remains. Can this adaptation, driven by natural selection, keep pace with global warming?</p>



<h2 class="wp-block-heading" id="h-the-case-of-the-palau-corals">The case of the Palau Corals</h2>



<p>For answers, the researchers turned to the serene corals of Palau in the western Pacific Ocean. The team built an eco-evolutionary simulation model of <a href="https://www.earth.com/news/healthy-coral-transplants-could-revolutionize-reef-restoration/" target="_blank" rel="noreferrer noopener">coral populations</a> using these corals.</p>



<p>They integrated data regarding the evolutionary biology of common but thermally sensitive corals and their ecology.</p>



<p>With this, the researchers determined the potential consequences of various future scenarios, considering global development and fossil fuel usage.</p>



<p>"Our world is expected to warm by 3-5 degrees by the end of this century if we do not achieve Paris Agreement commitments. Under such levels of warming, natural selection may be insufficient to ensure the survival of some of the more sensitive yet important coral species," cautioned study co-author Professor Peter Mumby from the <a href="https://uq.edu.au" target="_blank" rel="noreferrer noopener">University of Queensland</a>.</p>



<h2 class="wp-block-heading" id="h-future-of-corals-and-climate-change">Future of corals and climate change</h2>



<p>The models suggest dire consequences. We can foresee drastic reductions in reef health that will potentially push thermally sensitive coral species towards local extinction.</p>



<p>However, there is still room for hope as we don't yet fully understand the "evolvability" of coral populations.</p>



<p>Dr. James Guest, who leads the Coralassist Lab, emphasized the urgency for climate-smart management options. He also stressed the significance of collaborative efforts among researchers, conservationists, and policymakers to tackle the challenges faced by <a href="https://www.earth.com/news/multivitamins-could-save-coral-reefs-from-climate-destruction/" target="_blank" rel="noreferrer noopener">coral populations</a>.</p>



<p>By promoting interdisciplinary collaborations and knowledge-sharing, we can develop comprehensive strategies that address the complex interplay of environmental and genetic factors impacting coral resilience. </p>



<p>This multidisciplinary approach will be crucial in formulating effective management plans and conservation initiatives.</p>



<h2 class="wp-block-heading" id="h-investing-in-research-and-innovation">Investing in research and innovation</h2>



<p>According to Dr. Guest, there is a crucial need to invest in research and innovation to mitigate the threats faced by coral populations.</p>



<p>"One such option, still at the experimental stages to date, would be the use of targeted assisted evolution interventions that, for&nbsp;instance, could improve heat tolerance through selective breeding," Dr. Guest said, offering up a glimmer of hope.</p>



<p>By expanding our understanding of coral evolvability and exploring novel techniques, such as assisted evolution interventions, we can unlock innovative solutions to enhance coral resilience.</p>



<p>Increased funding and support for scientific research will enable us to develop new tools, technologies, and strategies that empower us to safeguard coral <a href="https://www.earth.com/news/crown-of-thorns-starfish-thrive-in-degraded-coral-reefs/" target="_blank" rel="noreferrer noopener">ecosystems</a> for generations to come.</p>



<h2 class="wp-block-heading" id="h-urgent-need-for-climate-action">Urgent need for climate action</h2>



<p>In the end, it all circles back to the dire need for immediate climate action. </p>



<p>“Taken together, the results of our models suggest that genetic adaptation could offset some of the projected loss of coral reef functioning and biodiversity over the 21<sup>st</sup>&nbsp;Century, if rapid climate action can be achieved,” concluded Dr. Lachs.</p>



<p>Coral reefs - home to an astonishing range of marine life - are pivotal to our marine ecosystems. They are nature's treasure, and losing them would be tantamount to facing cultural and ecological bankruptcy.</p>



<p>The question remains: will we act in time to save coral reefs from climate change? Or will we merely spectate as these reefs slowly fade into extinction?</p>



<p>The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.adl6480" target="_blank" rel="noreferrer noopener"><em>Science</em></a>.</p>

Coral reefs may not adapt quickly enough to survive climate change

They say the sea has many secrets, but the intriguing...

<p>Imagine&nbsp;being&nbsp;able&nbsp;to&nbsp;add&nbsp;years to your life with just&nbsp;a little&nbsp;bit of&nbsp;physical activity. This&nbsp;is&nbsp;not a&nbsp;pipe dream.</p>



<p>Researchers&nbsp;from&nbsp;Griffith&nbsp;University have conducted&nbsp;a new study that found raising the level of&nbsp;movement may make a significant difference&nbsp;in&nbsp;extending&nbsp;one's&nbsp;lifespan.</p>



<p>The&nbsp;researchers&nbsp;concluded&nbsp;that&nbsp;being as active as the top 25&nbsp;percent&nbsp;of the population could help someone over&nbsp;40&nbsp;live&nbsp;for&nbsp;five extra years. That's&nbsp;equivalent&nbsp;to&nbsp;gaining an extra half-decade&nbsp;just&nbsp;by making movement a regular part of your day.</p>



<p>Whether it's a <a href="https://www.earth.com/news/walk-20-minutes-daily-to-boost-your-brain-power/" target="_blank" rel="noreferrer noopener">daily walk</a>, a cycling routine, or even taking the stairs more often, the path to a longer, healthier life is surprisingly accessible.</p>



<h2 class="wp-block-heading" id="h-physically-active-people-live-longer">Physically active people live longer</h2>



<p>Physical activity has long been known to improve health, but estimates on the specific benefits of different activity levels have varied. </p>



<p>This recent study used accelerometry - a more precise method than traditional surveys - to track physical activity levels across populations.</p>



<p>The findings? The benefits of physical activity were about twice as robust as previously believed.</p>



<p>According to the study, the most active quarter of individuals had a 73% <a href="https://www.earth.com/news/stair-climbing-linked-to-a-24-percent-lower-risk-of-mortality/" target="_blank" rel="noreferrer noopener">lower risk of death</a> compared to their least active counterparts. For the least physically active, even small changes could make a massive difference.</p>



<p>"A single, one-hour walk could potentially return a benefit of around six additional hours of life," said lead researcher Professor Lennert Veerman.</p>



<h2 class="wp-block-heading" id="h-potential-in-the-least-physically-active-people">Potential in the least physically active people</h2>



<p>Professor Veerman emphasized the opportunity of physical activity - particularly for the least active segment of the population.</p>



<p>"If the least active quartile of the population over age 40 were to increase their activity level to that of the most active quartile, however, they might live, on average, about 11 years longer," he explained.</p>



<p>While those who are already highly active may not see significant additional benefits, for others, the equivalent of just under three hours of walking per day could be transformative.</p>



<p>"This is not an unreasonable prospect, as 25% of the population is already doing it," Veerman noted.</p>



<h2 class="wp-block-heading" id="h-physical-inactivity-rivals-smoking">Physical inactivity rivals smoking</h2>



<p>The research team suggested that inactivity could rival <a href="https://www.earth.com/news/quitting-smoking-at-any-age-brings-big-and-immediate-health-benefits/" target="_blank" rel="noreferrer noopener">smoking</a> in terms of its health risks.</p>



<p>With other studies finding that each cigarette can take 11 minutes off a smoker’s life, the implications for doing some physical activity are profound.</p>



<p>Dr. Veerman highlighted the underestimated potential of exercise. "If there's something you could do to more than halve your risk of death, physical activity is enormously powerful," he said.</p>



<h2 class="wp-block-heading" id="h-building-a-healthier-future">Building a healthier future</h2>



<p>The findings also highlight the importance of creating environments that encourage movement. </p>



<p>For example, <a href="https://www.earth.com/news/walkable-neighborhoods-help-reduce-cardiovascular-risk/" target="_blank" rel="noreferrer noopener">walkable neighborhoods</a> and accessible cycling paths could promote activity, reduce healthcare pressures, and improve environmental sustainability.</p>



<p>This study from <a href="https://www.griffith.edu.au/" target="_blank" rel="noreferrer noopener">Griffith University</a> reinforces the need for governments to revisit national physical activity guidelines.</p>



<p>The message is clear: even modest increases in movement can unlock extraordinary health benefits and transform societal well-being. </p>



<h2 class="wp-block-heading" id="h-global-implications-of-physical-activity">Global implications of physical activity</h2>



<p>The benefits of becoming more physically active extend beyond individual health. On a global scale, promoting <a href="https://www.earth.com/news/active-aging-physical-activity-has-a-direct-impact-on-life-quality/" target="_blank" rel="noreferrer noopener">active lifestyles</a> could reduce the burden of chronic diseases, lower healthcare costs, and even combat climate change.</p>



<p>As cities around the world grapple with rising rates of sedentary behavior, the study’s findings offer a powerful incentive to invest in infrastructure that encourages movement.</p>



<p>Studies have shown that active commuters often report better mental health and lower rates of chronic illnesses, making this a win-win for both personal and planetary health.</p>



<h2 class="wp-block-heading" id="h-bringing-movement-into-the-workplace">Bringing movement into the workplace</h2>



<p>This study also shines a light on how workplaces can make a difference. Let’s face it, many of us spend most of our day sitting at a desk - barely moving.</p>



<p>But what if workplaces could encourage healthier habits? Small changes like standing desks, walking meetings, or even rewards for taking the stairs could make a big impact.</p>



<p>Not only would this help employees stay healthier, but it could also make work more enjoyable. </p>



<p>Studies show that moving more can reduce stress, boost energy levels, and even help with focus.</p>



<p>By creating spaces that make it easier to stay active, companies could help employees feel better and be more productive.</p>



<p>The full study is published in the <em><a href="https://pubmed.ncbi.nlm.nih.gov/39542739/">British Journal of Sports Medicine</a></em>.</p>

Becoming more physically active could add 11 years to your life

Imagine&nbsp;being&nbsp;able&nbsp;to&nbsp;add&nbsp;years to your life with just&nbsp;a little&nbsp;bit of&nbsp;physical activity. This&nbsp;is&nbsp;not...

<p>Over the past 20 years, scientists have observed a subtle but widespread shift in the color of our oceans. While these changes might not be noticeable during a day at the beach, you can easily see them from airplanes and satellites in space.</p>



<p>This is happening on a massive, global scale, signaling to anyone paying attention that significant transformations are taking place beneath the surface of our seas.</p>



<h2 class="wp-block-heading" id="h-sounding-alarm-bells">Sounding alarm bells</h2>



<p>Stephanie Dutkiewicz, a senior research scientist at <a href="https://www.mit.edu" target="_blank" rel="noreferrer noopener">MIT</a>, has been studying this phenomenon closely. She's part of a team that's raising concerns about what these color changes mean for the health of our planet.</p>



<p>"We hope people take this seriously," says Dutkiewicz. "It's not only models predicting these changes; we can now see them happening, and the ocean is changing."</p>



<p>In a study published in <em>Nature</em>, researchers from the <a href="https://noc.ac.uk/" target="_blank" rel="noreferrer noopener">National Oceanography Center</a> in the UK and other institutions revealed that more than half of the world's oceans have experienced a shift in color. </p>



<p>They found that these changes can't be chalked up to natural variations alone -- they're likely a result of human-driven climate change.</p>



<h2 class="wp-block-heading" id="h-greener-ocean-color-near-the-equator">Greener ocean color near the equator</h2>



<p>Tropical regions near the equator have become noticeably greener over time. This isn't just a visual tweak; it's a sign that the ecosystems within the surface ocean are changing. </p>



<p>The color of the ocean is influenced by what's in its upper layers, especially tiny organisms like phytoplankton.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/11/earth-ocean-waters_south-carolina-coast_landsat8_green-color_nasa-1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/11/earth-ocean-waters_south-carolina-coast_landsat8_green-color_nasa-1s.webp" alt="Winyah Bay (roughly midway between Charleston and Myrtle Beach, South Carolina) receives input from a number of blackwater rivers whose dark, reddish hues arise from the absorptive properties of colored dissolved organic matter (CDOM) which some have likened to nature's tea.

<p><a href="https://www.earth.com/news/invisible-forest-of-phytoplankton-thrives-in-a-warming-climate/" target="_blank" rel="noreferrer noopener">Phytoplankton</a> are microscopic, plant-like creatures that contain chlorophyll, giving them their green tint. They're a cornerstone of the marine food web and play a key role in capturing carbon dioxide from the atmosphere. </p>



<p>Shifts in their populations can have ripple effects throughout marine ecosystems and impact the global carbon cycle.</p>



<h2 class="wp-block-heading" id="h-blame-the-humans-of-course">Blame the humans, of course</h2>



<p>Lead author B.B. Cael from the National Oceanography Center points out that this isn't a random occurrence. </p>



<p>"This evidence shows how human activities are affecting life on Earth on a vast scale," he says. "It's another way humans are impacting the biosphere, affecting even the most extensive environments on the planet."</p>



<p>Traditionally, scientists have monitored <a href="https://www.earth.com/news/marine-algae-genes-chlorophyll-boost-crop-yields-land-plants/" target="_blank" rel="noreferrer noopener">chlorophyll levels</a> to keep tabs on phytoplankton populations. But tracking changes using chlorophyll alone can take decades because of natural year-to-year fluctuations. </p>



<p>Back in 2019, Dutkiewicz and her colleagues suggested that looking at the full spectrum of ocean colors could reveal climate change-driven trends more quickly. They estimated that such changes could become apparent within 20 years.</p>



<h2 class="wp-block-heading" id="h-satellites-spot-the-difference">Satellites spot the difference</h2>



<p>The team analyzed data from the Moderate Resolution Imaging Spectroradiometer (<a href="https://modis.gsfc.nasa.gov/" target="_blank" rel="noreferrer noopener">MODIS</a>) on NASA's Aqua satellite. </p>



<p>Since 2002, this instrument has been observing ocean color across seven visible wavelengths. Their analysis showed a clear trend over two decades, lining up with what their models had predicted.</p>



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/11/earth-ocean-waters_new-zealand-coast_modis-satellite_nasa_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/11/earth-ocean-waters_new-zealand-coast_modis-satellite_nasa_1s.webp" alt="Phytoplankton blooms are evident throughout the South Pacific Ocean with sediment re-suspended from the ocean floor by waves and tides along much of the New Zealand coastline.

<p>Cael explains that these trends match up with the effects of <a href="https://www.earth.com/news/human-induced-changes-in-ocean-salinity-threaten-biodiversity-and-marine-ecosystems/" target="_blank" rel="noreferrer noopener">human-induced</a> climate change, not just random shifts in the Earth's system. </p>



<p>This means the changes in ocean color are a direct response to how we're altering the planet's climate.</p>



<h2 class="wp-block-heading" id="h-why-does-ocean-color-matter">Why does ocean color matter?</h2>



<p>So, what's the big deal about the ocean turning a bit greener? It suggests that the types of <a href="https://www.earth.com/news/plankton-at-risk-global-warming-threatens-the-oceans-lifeline/" target="_blank" rel="noreferrer noopener">phytoplankton communities</a> are changing. </p>



<p>Different phytoplankton have varying abilities to capture carbon and support marine life. Changes in these communities can affect the entire food web, from tiny marine organisms all the way up to fish and whales.</p>



<p>Dutkiewicz emphasizes that these shifts will impact all creatures that rely on plankton for food. </p>



<p>"Different types of plankton influence how much carbon the ocean can absorb," she notes, highlighting the broader implications for climate regulation.</p>



<h2 class="wp-block-heading" id="h-visible-sign-of-invisible-changes">Visible sign of invisible changes</h2>



<p>This research shines a light on the far-reaching effects of climate change on <a href="https://www.earth.com/news/overfishing-and-habitat-degradation-have-devastated-marine-ecosystems/" target="_blank" rel="noreferrer noopener">marine ecosystems</a>. Monitoring ocean color offers a tangible way to detect and understand these shifts. </p>



<p>The findings are a stark reminder of the significant impact human activities have on Earth's complex systems.</p>



<p>"The evidence is clear: human activities are altering the very color of our oceans," says Cael. This isn't just about aesthetics; it's about the intricate balance of marine life that keeps our planet healthy.</p>

<p>This shift in the ocean's hue is more than just a scientific curiosity -- it's a call to action. </p>



<p>Scientists are continuing to study these trends to grasp the full impact on marine ecosystems and the global climate.</p>



<p>By keeping a closer eye on the full spectrum of ocean colors, researchers hope to gain a quicker understanding of how climate change is affecting the oceans.</p>

<p>This could lead to faster responses and more effective strategies to lessen the impacts.</p>



<p>As we face the realities of climate change, understanding what's happening in our oceans is crucial. Changes in the oceans can affect weather patterns, sea levels, and biodiversity on a global scale.</p>



<p>Addressing these challenges isn't something scientists can do alone. It requires all of us to pitch in -- from reducing our carbon footprints to supporting policies that protect marine environments. </p>



<p>Every action, no matter how small, contributes to the bigger picture.</p>



<h2 class="wp-block-heading" id="h-ocean-color-climate-change-and-human-health">Ocean color, climate change, and human health</h2>



<p>To sum it all up, scientists have noticed that over the past 20 years, more than half of the world's oceans have subtly changed color. </p>



<p>Stephanie Dutkiewicz points out that this shift matches what climate change models have been predicting. </p>



<p>The color change is linked to alterations in phytoplankton communities -- tiny, plant-like organisms with chlorophyll that give the ocean its green tint. </p>



<p>These little guys are essential for marine life and play a big role in capturing carbon dioxide from the atmosphere.</p>



<p>By analyzing satellite data, researchers found that these changes aren't just natural fluctuations; they're consistent with human-driven climate change. </p>



<p>The shift in ocean color suggests significant changes in marine ecosystems, which could impact the entire food web -- from microscopic organisms to large marine animals. </p>



<p>This finding highlights how human activities are affecting the planet in profound ways, even down to changing the very color of our oceans. It's a clear sign that we need to take climate change seriously and start making changes now.</p>

Earth's oceans are rapidly changing colors, and humans are directly to blame

Over the past 20 years, scientists have observed a subtle...

<p>For those observing Arctic climate change from a distance, the picture often seems straightforward - warming is a detrimental process that leads to melting ice caps and rising sea levels. However, as is often the case, the reality is far more complex.</p>



<p>A group of Japanese researchers studying the intricacies of the Arctic have provided further proof of this complexity.</p>



<p>When considering the Arctic climate, one truth emerges: things are heating up, and fast. The region is warming at a rate of two to four times faster than the global average. This raises a critical question - what is driving the rapid escalation in Arctic temperatures?</p>



<p>This phenomenon, known as <a href="https://www.earth.com/news/arctic-amplification-is-destabilizing-the-delicate-balance-of-the-ecosystem/" target="_blank" rel="noreferrer noopener">Arctic amplification</a>, is not only reshaping the local environment but is also influencing global climate systems.</p>



<p>Unraveling its causes requires looking beyond ice and temperatures to less obvious factors, like Arctic dust.</p>



<h2 class="wp-block-heading" id="h-arctic-dust-an-unexpected-player">Arctic dust: An unexpected player</h2>



<p>In a world where we often view dust as little more than an inconvenience, researchers have found that it plays a significant role in Arctic warming.</p>



<p>According to the results of a recent study, dust (specifically that originating from snow- and ice-free areas of the Arctic) has been linked to the accelerated warming of the region.</p>



<p>In the prevalent understanding, it's commonly believed that increases in <a href="https://www.earth.com/news/arctic-temperatures-rise-when-plants-stop-breathing/" target="_blank" rel="noreferrer noopener">Arctic temperatures</a> are associated with more liquid droplets and fewer ice crystals populating the region's clouds.</p>



<p>This combination is thought to give rise to thicker, longer-lasting clouds that have a higher likelihood of reflecting sunlight, thereby potentially cooling the region during summer. This is what is generally known as temperature feedback.</p>



<h2 class="wp-block-heading" id="h-expansion-of-snow-and-ice-free-areas">Expansion of snow- and ice-free areas</h2>



<p>However, the Japanese researchers paint a different picture. Their study has shown that the warming Arctic is associated with an expansion of snow- and ice-free areas.</p>



<p>This increase leads to a concomitant rise in dust emissions, which encourage the formation of ice crystals in the clouds. </p>



<p>Thinner, less lasting clouds are one consequence of the ice crystals in the clouds, meaning that less sunlight is reflected and the Arctic becomes warmer during summer. The researchers have termed this the "emission feedback."</p>



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



<p>The lead author of the study, Professor Hitoshi Matsui of <a href="https://en.nagoya-u.ac.jp/" target="_blank" rel="noreferrer noopener">Nagoya University</a>, provides valuable insight into this intricate phenomenon.</p>



<p>"Increasing amounts of dust due to <a href="https://www.earth.com/news/arctic-warming-permafrost-melt-devastating-role-accelerating-global-climate-change/" target="_blank" rel="noreferrer noopener">Arctic warming</a> may cause the opposite phenomenon of the conventional understanding of ice crystal changes," he remarked.</p>



<p>"Our previous study found that a large amount of Arctic dust is distributed in the lower troposphere (below about 3 km in altitude) over the region in summer and early fall, with the dust acting as a very efficient nucleus for ice formation in clouds at this altitude during the season."</p>



<h2 class="wp-block-heading" id="h-looking-back-looking-ahead">Looking back, looking ahead</h2>



<p>For their investigation, Professor Matsui, Dr. Kei Kawai, and their colleagues from the National Institute of Polar Research and Hokkaido University, utilized the CAM-ATRAS global aerosol-climate model. </p>



<p>They examined how dust emissions from the Arctic land surface have changed over a span of forty years, from 1981 to 2020.</p>



<p>The findings were telling - dust emissions rose by 20% in this period, as the Arctic continued to warm.</p>



<h2 class="wp-block-heading" id="h-arctic-dust-and-ice-crystal-formation">Arctic dust and ice crystal formation</h2>



<p>The increase in Arctic dust emissions bolsters ice nucleation in clouds in the lower troposphere, undermining the efficiency of clouds to carry more liquid droplets and fewer ice crystals as the Arctic warms. </p>



<p>The researchers found that in 30% of the region annually, and 70% in summer, the growth in ice crystal formation due to increased dust outweighs the reduction brought about by temperature feedback.</p>



<p>"Most <a href="https://www.earth.com/news/weather-in-dry-regions-isnt-behaving-as-climate-models-predict/" target="_blank" rel="noreferrer noopener">climate models</a> have not considered the effects of dust from the Arctic land surface. Our research suggests that the counterbalancing temperature and emission feedbacks should be considered to improve the accuracy of climate change predictions in the Arctic," noted Matsui.</p>



<p>So, as we continue to grapple with the realities of <a href="https://www.earth.com/news/climate-change-earth-energy-imbalance-temperature-rise/" target="_blank" rel="noreferrer noopener">climate change</a>, these insights underline the need to recognize the nuanced relationship between Arctic warming and Arctic dust.</p>



<p>It's a reminder of how interconnected our world is, and how a deeper understanding of these connections can help us make better predictions and, perhaps, better decisions for our planet's future.</p>



<p>The full study was published in the journal <em><a href="https://www.nature.com/articles/s41612-024-00811-1" target="_blank" rel="noreferrer noopener">npj Climate and Atmospheric Science</a></em>.</p>

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

Scientists discover we age in bursts

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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



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



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



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