We tend to explain the world by pointing to what things are, not what they’re interacting with. A new analysis argues that this bias has repeatedly steered science down blind alleys. 



The pattern shows up in classic missteps and in how people, even experts, reason today. The upshot: human cognition nudges theory toward inherent properties and away from the environment.



A team of psychology researchers from the <a href="https://www.ed.ac.uk/" target="_blank" rel="noreferrer noopener">University of Edinburgh</a> and <a href="https://www.nyu.edu/" target="_blank" rel="noreferrer noopener">New York University</a> mapped this recurring bias across history and in modern minds.



“Early scientific theories across multiple fields share a common pattern, in that they focus too much on built-in features and too little on interactions with surroundings,” said Zachary Horne, a lecturer in psychology at the University of Edinburgh and the paper’s lead author.



“This bias appears throughout the history of science, and its ‘fingerprints’ can even be seen among scientists today.”



<h2 class="wp-block-heading" id="h-the-bias-behind-early-theories"><a></a>The bias behind early theories</h2>



The authors argue that many foundational explanations leaned on assumed inner essences. Medieval accounts of motion, for example, claimed projectiles carried an internal “impetus” that kept them going until it ran out. Only later did Galileo and Newton replace this with dynamics grounded in external forces.



Study co-author Andrei Cimpian highlighted the cost of our default lens: “Some of the most significant achievements have come about as a result of scientific ingenuity," he said.



"But our <a href="https://www.earth.com/news/how-does-the-brain-process-experiences-over-time/">cognitive processes</a>, which favor explaining phenomena in terms of their inherent properties rather than external factors, seem to have historically slowed scientific discovery.” 



The researchers use the label “inherence bias” for this systematic tilt toward built-in features.



<h2 class="wp-block-heading" id="h-repeated-bias-in-science">Repeated bias in science</h2>



To test whether this pattern is widespread, the team surveyed historians of science in the U.S., Canada, and the U.K. Each historian listed major transitions: the initial explanation for an observation and the later, more accurate account. 



One example is the explanation of tides. Early observers described them simply as the “tidal motions of Earth’s large bodies of water.” 



Galileo suggested they were caused by the sloshing of oceans due to Earth’s motion, an idea researchers later categorized as an “inherent” explanation. 



Over time, however, this view was replaced by a more accurate understanding. Johannes Kepler and Isaac Newton demonstrated that tides are driven by the gravitational pull of the Moon - a model coded as “extrinsic” by the researchers.



Doctoral students trained in philosophy of science coded the responses as “inherent” or “extrinsic.” The vast majority of the nearly 80 initial explanations emphasized inherent properties; later explanations showed much less of that emphasis.



<h2 class="wp-block-heading" id="h-brownian-motion-as-a-case-study"><a></a>Brownian motion as a case study</h2>



Robert Brown’s 1827 observations offer a vivid example. Under the microscope, pollen grains suspended in water jittered. 



Early on, many biologists invoked a “vital force” inside living matter. But the pattern didn’t fit the data.



Decades later, the correct mechanism pointed outward: rapid, unseen <a href="https://www.earth.com/news/organic-molecules-found-throughout-the-universe-hint-that-life-began-in-deep-space/">molecules</a> in the surrounding water battering the grains. What looked like life’s essence was really interaction - now textbook “Brownian motion.”



<h2 class="wp-block-heading" id="h-today-s-scientists-fall-for-bias">Today’s scientists fall for bias</h2>



The authors then asked whether contemporary minds fall into the same groove. They ran experiments with practicing scientists, adult non-scientists, and children aged five to nine. Participants received real scientific observations they were unlikely to know and were asked to explain them.



Children, for instance, got: “why a hammer fell at the same speed as a feather on the Moon.” Adult non-scientists were asked to explain sediment appearing in distilled water after boiling. 



Scientists confronted harder puzzles, such as why some <a href="https://www.earth.com/news/astronomers-announce-evidence-suggesting-that-our-solar-system-has-nine-planets-again/">planets</a> lose mass over time, why a planet might have a given magnetosphere size, or why the tadpoles of the poisonous dart frog are not poisonous.



Across groups, first-pass theories leaned inward. When faced with sediment in boiled distilled water, one non-scientist reasoned that “heat caused the water to begin to turn into soil” - a throwback to ancient thinking.



Even experts showed the same pull, if in more technical language. On planetary mass loss, some cited “ejecta from volcanoes” and “transformation of matter on the planet into gas that dissipates away from the planet,” proposals that downplayed complex star-planet interactions.



<h2 class="wp-block-heading" id="h-fixing-science-starts-with-minds">Fixing science starts with minds</h2>



The researchers emphasized that these are not failures of scientists so much as features of human cognition. The world’s messiness tempts us to reach for what seems built in. That tendency can be productive at times, but it also detours progress when the real drivers are external forces and interactions.



“The path from initial explanatory intuitions to mature scientific understanding is rarely straightforward,” the authors wrote.



“This work suggests that one systematic source of detours may lie in our cognitive architecture itself - in the basic <a href="https://www.earth.com/news/how-the-human-brain-processes-visual-information/">information processing</a> constraints that guide how we first attempt to make sense of unfamiliar phenomena." 



"Understanding these constraints is crucial not just for advancing cognitive science, but also for improving how we train future generations of scientists.”



<h2 class="wp-block-heading" id="h-one-bias-shapes-science-s-path">One bias shapes science’s path</h2>



History’s wrong turns were not random. They followed a recognizable bias toward inherent properties. That same bias shows up today in children, laypeople, and trained researchers when they explain unfamiliar phenomena.



Recognizing the pull of “inherence bias” can help teachers and scientists nudge thinking outward - toward context, interaction, and the environment - so our next theories start closer to the truth.



 The study is published in the journal <a href="https://doi.org/10.1073/pnas.2424725122" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.

Centuries of scientific errors reveal a hidden human bias

We tend to explain the world by pointing to what things are, not what they’re interacting with. A new analysis argues that this bias has repeatedly steered science down blind alleys. The pattern shows up in classic missteps and in how people, even experts, reason today. The upshot: human cognition nudges theory toward inherent properties and away from the environment. A team of psychology researchers from the University of Edinburgh and New York University mapped this recurring bias across history and in modern minds. “Early scientific theories...

Experts at <a href="https://wustl.edu/">Washington University in St. Louis</a> are describing how hummingbirds use torpor, a hibernation-like state of inactivity, to survive harsh <a href="https://www.earth.com/news/environmental-dna-can-help-monitor-pollinators/">environments</a>. According to the study, hummingbirds use torpor in different ways depending on their physical state and the environmental conditions they are facing.&nbsp;



In collaboration with biologists in Colombia, the researchers caught 249 hummingbirds (29 different species) living in the middle to high altitudes of the Andes Mountains. The experts wanted to measure torpor under various semi-natural conditions.&nbsp;



“Torpor is somewhere between a power nap and hibernation,” said study first author Justin Baldwin. “Earlier research had suggested that torpor was a way of completely shutting metabolism down to minimal levels."



"Our findings join a growing body of evidence to suggest that when animals enter torpor, they have diverse options to calibrate aspects of torpor to their environment.”



The study revealed that hummingbirds can enter into deep or shallow torpor, and they can remain in this state for just a few hours or for the entire night. In addition, the birds can begin to emerge from torpor hours or just minutes before sunrise.&nbsp;



"Small birds were more likely to use torpor than large birds, but only at low ambient temperatures, where torpor was prolonged. We also found effects of proxy variables for body condition and energy expenditure on the use of torpor, its characteristics, and impacts," wrote the researchers.



Study co-author Gustavo Londoño is a professor at the Universidad Icesi in Cali, Colombia. He explained that torpor can be the difference between surviving through cold night-time temperatures encountered at high elevations, or dying trying to regulate their body temperature using fuel from their internal reserves.



“One of the new things we learned with this study is that hummingbirds start exiting torpor more or less one hour before sunrise,” said Professor Londoño. “Being out of torpor and ready to fly with the first sunlight is key to ensuring that their first meal will be from flowers that are full of nectar. The flowers then get depleted through the morning.”



By studying many hummingbird species at once, the researchers were able to analyze how torpor may have contributed to their evolution and colonization of harsh environments.



“Species that more readily deployed torpor at our study sites also occurred at higher elevations across the entire Andean region,” said Baldwin. “This is exciting, because it suggests that a characteristic of bird physiology can tell us something about their distribution across the entire continent."



“Even though we don’t know which came first - an increase in readiness to use torpor or the ability to persist at high elevations - we think that hummingbirds’ readiness to use torpor is likely tied to their evolutionary conquest of mountain habitats.”



&nbsp;The study is published in the journal <a href="http://dx.doi.org/10.1098/rspb.2022.2099">Proceedings of the Royal Society B Biological Sciences</a>.

Hummingbirds have evolved to survive harsh environments 

Experts at Washington University in St. Louis are describing how...

Over 85 percent of the Earth’s mammal, bird, and amphibian species live in mountain forests. Unfortunately, these forests are disappearing at an alarming rate.



According to a new study led by the <a href="https://www.leeds.ac.uk/">University of Leeds</a> in the UK and the <a href="https://www.sustech.edu.cn/en/">Southern University of Science and Technology</a> in China, 78.1 million hectares (7.1 percent) of mountain forests have been lost since the beginning of the new millennium. This is an area larger than the size of Texas. Most of this loss has occurred in tropical <a href="https://www.earth.com/news/protected-areas-are-failing-to-safeguard-biodiversity/">biodiversity</a> hotspots, thus significantly threatening a variety of already endangered animal species.&nbsp;



Forested mountain areas were previously protected from deforestation by their rugged location. But as lowland regions became depleted or subject to protection at the beginning of the 21st centuries, mountain forests became increasingly exploited. 



To clarify the current situation, the experts tracked changes in mountain forests on an annual basis from 2001 to 2018, measuring both losses and gains in tree cover, estimating the rate at which change was occurring, comparing different elevations and types of forests (such as boreal, tropical, or temperate), and exploring the impacts of forest loss on biodiversity.



“Knowledge of the dynamics of forest loss along elevation gradients worldwide is crucial for understanding how and where the amount of forested area available for forest species will change as they shift in response to warming,” the authors explained.



The investigation revealed that logging was the main driver of forest loss (42 percent), followed by wildfires (29 percent), shifting or “slash-and-burn” cultivation (15 percent), and permanent or semi-permanent agricultural practices (10 percent). However, the importance of these factors was found to differ from region to region. The most significant losses occurred in Asia, South America, Africa, Europe, and Australia, with North America and Oceania appearing to fare slightly better.



Unfortunately, the rate of mountain forest loss appears to be accelerating, with the annual rate of loss rising by 50 percent from the 21st century’s first to second decade (which witnessed about 5.2 million hectares annual losses). This acceleration is likely driven by the rapid agricultural expansion into highland regions in mainland Southeast Asia, as well as by increased logging due to either depletion or protection of lowland forests.



Although tropical forests experienced the greatest loss (42 percent of the global total), they also had a faster rate of regrowth compared to temperate and boreal mountain forests. While protected areas experienced less forest loss than unprotected ones, this may not be sufficient to protect endangered species.



“Regarding sensitive species in biodiversity hotspots, the critical issue extends beyond simply preventing forest loss. We must also maintain the integrity of forests in large enough zones to allow natural movements and sufficient space for ranging species,” the authors wrote.



The researchers concluded by highlighting the importance of reaching a balance between the protection of forests and human livelihoods. “Any new measures to protect mountain forests should be adapted to local conditions and contexts and need to reconcile the need for enhanced forest protection with ensuring food production and human wellbeing.”

Besides warmer weather and blooming flowers, spring also brings the unfortunate re-emergence of the <a href="https://www.earth.com/news/spotted-lanternflies-damage-young-maple-trees/">spotted lanternfly</a>, a prolific invasive insect originating from Asia that wreaks havoc on both forests and croplands. Since their initial detection in Pennsylvania in 2014, these insects have spread to over 100 counties across 14 states. 



Now, a study published in the journal <a href="http://dx.doi.org/10.1038/s41598-022-25989-3">Nature Scientific Reports</a> has found that the spread of spotted lanternflies is largely due to human-mediated dispersal via transportation by cars, trucks, and trains.



“Spotted lanternflies can spread quickly into suitable habitat and have the potential to cause significant economic damage to crops and hardwood trees,” said study co-author Tara Trammell, an associated professor of Urban Forestry at the <a href="https://www.udel.edu/">University of Delaware</a>. “Studying potential dispersal mechanisms, such as human transportation, can help us develop management approaches to reduce further spread.”



To simulate spotted lanternfly spread dynamics, the experts used agent-based models incorporating information on life history, habitat suitability, movement, and natural dispersal behaviors. The analysis revealed an overwhelming effect of human-mediated dispersal that supports current observational data and could finally explain the mysterious long-distance jumps across states this insect has made. 



Human-mediated dispersal most likely occurs during the period between June and September, when both juvenile and adult lanternflies are present. This is also when mating and egg laying take place.&nbsp;



“The primary mode of human-mediated dispersal is still to be determined. For example, it could be egg masses laid on vehicles or gravid females hitchhiking on vehicles,” said study lead author Zach Ladin, a supervisory wildlife biologist at the <a href="https://www.fws.gov/">U.S. Fish and Wildlife Service</a>.



“That would be a great follow-up experiment. Future studies could mark and track egg masses on train cars and measure egg mass survival, or mark and track hitchhiking nymphs and adults on tractor trailers.”&nbsp;



While proving the critical role of human behavior in the wide dispersal of this invasive species is a crucial first step, slowing their spread requires further public education and outreach. If measures to modify human behavior are not urgently taken, the spotted lanternflies will spread quickly to every suitable habitat across North America, with unpredictable economic and ecological impacts.



“The number one suggestion is to follow state recommended guidelines for monitoring vehicles. We suggest people in areas with established spotted lanternfly populations be vigilant when traveling across state lines and follow suggested protocols for monitoring their vehicles when going on long-distance trips,”&nbsp;Ladin advised.



Other measures could include the use of insecticides and traps in late spring, summer, and early fall, and scraping egg masses to prevent the next generation of lanternflies from hatching in winter and early spring.



“Additionally, management and removal of the suite of host trees that spotted lanternflies use to reproduce will help diminish the number of individuals on the landscape, which can lower the likelihood of spotted lanternfly hitchhikers and the establishment in previously unoccupied habitat,” Ladin concluded.

A recent experimental study led by the <a href="https://www.oist.jp/">Okinawa Institute of Science and Technology</a> (OIST) in Japan has found that future ocean warming and marine heatwaves may impact the growth and development of <a href="https://www.earth.com/news/clownfish-adapt-their-size-to-fit-their-environment/">clownfish</a> (Amphiprion ocellaris) during their earliest life stages, with the larvae growing faster, having higher metabolic rates, and showing changes in the activity of certain genes in warmer temperatures.



During the first 20 days of their lives, clownfish pass through several developmental stages, marked by important environmental and behavioral changes in the wild. Soon after hatching, clownfish larvae are carried from their home reef to the open ocean where, after roughly ten days, they start to develop their iconic orange-white colors. Around day 14, they find a new reef where they seek out and settle into an anemone host.&nbsp;



To assess how warmer temperatures may impact this developmental timeline, the experts reared clownfish in captivity at water temperatures of either 28°C (the current summer ocean temperature in Okinawa) or 31°C (the estimated seawater temperatures triggered by global warming by the end of the century). The experiment revealed that the larvae reared at higher temperatures hit their developmental milestones around two days earlier than those reared at current temperatures, and exhibited higher metabolic rates, most likely driving their faster growth rates.&nbsp;



In addition, at each stage of their development, clownfish reared at 31°C showed either increased or decreased activity in over 450 genes, with several genes associated with heat-stress being more active from the earliest developmental stages, while genes involved in neurotransmission decreasing their activity at later stages, meaning that higher temperatures could lead to changes in clownfish cognition and behavior.



However, predicting how these metabolic and genetic modifications will impact the survival of clownfish under increased heat stress remains a major challenge. “On the one hand, the majority of clownfish do not survive the larval period due to predation, so shortening this time could increase their chances of survival and settlement. On the other hand, faster development may mean the clownfish disperse to new reefs less effectively, and the larvae may not be able to take in sufficient food to meet their increased energy demands,” explained lead author Billy Moore, a doctoral student in Marine Biology at OIST.



Finally, the experiments also revealed changes in the epigenome (the set of chemical compounds which modify the genome in ways “telling” it what to do, where to do it, and when to do it) of clownfish raised in warmer temperatures.&nbsp;



“We are now beginning experiments to study how the epigenome differs between clownfish raised at 31°C compared to 28°C. This could have really important implications as epigenetic changes laid down in the early stages of development impact how individuals respond to changes and stresses in the environment during their adult life,” Moore concluded.



The study is published in the journal <a href="http://dx.doi.org/10.1016/j.scitotenv.2023.162296">Science of the Total Environment</a>.

Ocean warming impacts the development of clownfish

A recent experimental study led by the Okinawa Institute of...

During the past decades, <a href="https://www.earth.com/news/southern-resident-killer-whales-are-undernourished/">Southern resident killer whale</a> populations in the Pacific Northwest have declined substantially, leading researchers to look for causes of this worrisome trend. Some of the threats that have been identified include fluctuations in salmon prey, exposure to toxic pollutants, and disturbance and noise from ships and other vessels.&nbsp;



Now, by combining modern genomics with decades of field observations, an international team of scientists has found that the small size and isolation of the endangered population of Southern residents in the Pacific Northwest have led to high levels of inbreeding. This phenomenon has significantly contributed to their decline.



“For a long time, we’ve struggled to understand why this population has consistently lower survival and birth rates than other killer whales in the region, and this research highlights a strong link between inbred individuals and increased risk of death,” said study co-author Eric Ward, a statistician at the <a href="https://www.fisheries.noaa.gov/about/northwest-fisheries-science-center">Northwest Fisheries Science Center</a>. “It’s a view we’ve never had before, and it begins to fill a gap in our understanding.”



Killer whales reproduce for the first time at around ten years of age and reach their reproductive prime in their twenties. However, the researchers discovered that, compared to the least inbred whales, highly inbred ones had less than half the chance of surviving through those years to reach 40. While females with low levels of inbreeding usually live long enough to produce an average of 2.6 offspring during their lifespan, those with high levels of inbreeding produce an average of only 1.6 offspring during their significantly shorter lives – which is insufficient for animal populations to remain stable or increase.&nbsp;



Moreover, since inbreeding significantly limits the population’s growth and recovery, the whales become much more vulnerable to a variety of other threats, such as disease, limited prey, or exposure to contaminants and human disturbances.



“The whales are not necessarily dying of inbreeding itself, they are dying prematurely because inbreeding has set them up to be more vulnerable to diseases or other problems,” said co-author Bradley Hanson, a research scientist at the Northwest Fisheries Science Center. “We need to minimize the potential for those factors to have an impact.”



“It would be a mistake to see this as inbreeding alone causing the decline. Over the last 50 years, this population has been impacted by multiple stressors, and the relative impact of various threats on the Southern resident population has fluctuated through time. These combined impacts, coupled with the mating system of killer whales—where only a few males are contributing to the gene pool—may have made inbreeding a more significant threat in recent years,” Ward concluded.



The study is published in the journal <a href="https://www.nature.com/articles/s41559-023-01995-0">Nature Ecology &amp; Evolution</a>.

All over the world, forests are being increasingly reduced by human activities to smaller remnants scattered among the agricultural lands that have often replaced them. This has a marked negative impact on the ecosystems previously supported by forests, including a variety of bird populations, with the majority of bird species now struggling to survive in an increasingly human-dominated environment.&nbsp;



According to a recent study led by the <a href="https://www.utah.edu/">University of Utah</a>, for birds which used to inhabit the vast forests of Central America, the massive replacement of forested land with <a href="https://www.earth.com/news/coffee-plantations-tropical-birds/">coffee plantations</a> has significantly diminished the amount of their preferred foods, forcing them to change their diets and habitats in order to survive.



To examine changes in their diets, the researchers conducted isotope analyses of the feathers of four bird species (the orange-billed nightingale thrush, the silver-throated tanager, the white-throated thrush, and the ochre-bellied flycatcher) living in the land around the Las Cruces Biological Station in Costa Rica, whose previously luxurious forests have been largely replaced in recent years by coffee plantations.&nbsp;



Along with the radio tracking of their movements, the isotope analyses have revealed that birds eat fewer invertebrates in coffee plantations than in forests, suggesting that disruptions in their ecosystem significantly impacts their dietary options.



“Growing human ecological impact on the planet, especially via habitat loss and degradation and climate change, often impacts bird diets negatively as well,” said study lead author Çağan H. Şekercioğlu, a professor of Ecology and Ornithology at Utah. “These negative changes, including declines in key dietary resources like insects and other invertebrates can lead to reduced survival, especially of rapidly growing young, often leading to population declines and losses of these undernourished birds.”&nbsp;



To consume enough invertebrates – which offer them the necessary nutrients to survive – birds living in and around coffee plantations need to forage frequently in the small forest fragments and narrow forest corridors alongside rivers. While more mobile birds, such as the silver-throated tanager or the white-throated thrush move constantly to get their preferred, protein-rich food, less mobile species like the orange-billed nightingale thrush are forced to adapt to the poorer diets they can find in coffee plantations.&nbsp;



However, even for mobile birds, the situation is worse than it used to be. “These birds’ shifting their feeding to other places may result in new ecological interactions that can themselves have negative consequences,” Şekercioğlu explained. “For example, increased competition with birds in these new places or overpredation on a prey species that was formerly not consumed as much.”



To help protecting these bird populations, local governments in tropical regions should prioritize the conservation of intact forests, secondary growth forests, and strips of forest alongside rivers to increase the connectivity of forest remnants, while coffee-drinkers all around the world can choose to buy&nbsp;<a href="https://www.audubon.org/news/how-choose-bird-friendly-coffee">bird-friendly coffee</a> that is grown in plantations with more tree cover and forest remnants, which are beneficial for native birds.

California mountain lions continue to be threatened by human activities, despite being classified as specially protected mammals, according to a study led by the <a href="https://www.unl.edu/">University of Nebraska-Lincoln</a>.&nbsp;



The California Wildlife Protection Act of 1990 made it illegal to hunt mountain lions, but the researchers have determined that human-caused mortality is still more common than natural mortality among these animals. The biggest threats were found to be vehicle collisions and conflict with humans over <a href="https://www.earth.com/news/livestock-are-reservoirs-for-antimicrobial-resistant-pathogens/">livestock</a>.



For the investigation, experts from multiple universities, government agencies, and private organizations tracked hundreds of mountain lions across the state of California. The animals were located in many different study areas, including the Sierra Nevada Mountains and the city of Los Angeles.



“Population dynamics of large carnivores operate at large scales, making it critical for researchers to collaborate across broad geographic regions that go beyond typical study areas to better understand population processes and connectivity,” explained study co-lead author Professor John Benson.



The analysis revealed that mountain lions were at greater risk of human-caused mortality when they were closer to rural development. Mountain lions were found to be less threatened in areas where more voters favored pro-environmental initiatives.



“Ecologists believe that human tolerance is critical to conserving large carnivores in landscapes shared with humans. However, it is rare that data on tolerance are included in the models we use to understand mortality risk,” said Professor Benson. “Of course, we acknowledge that voting records on environmental issues are not a direct reflection of this tolerance, but the strength of this result suggests that human mindset may be an important driver of mortality risk for mountain lions.”



According to the experts, the new research highlights the importance of understanding interrelationships between different populations across California for long-term conservation of the species.



“Young male mountain lions often move and breed long distances from where they were born, and are largely responsible for maintaining gene flow between populations,” said study co-lead author Kyle Dougherty. “Immigration of mountain lions from adjacent or more distant populations can also help compensate for high rates of human-caused mortality and maintain population persistence through a process known as ‘source-sink’ dynamics.”



“We tend to focus on survival of adult females because of their strong influence on growth or decline of individual populations,” said study co-author Justin Dellinger. “However, young males are the ones that move between populations meaning that their mortality, combined with barriers to movement imposed by roads and development, could limit the utility of seemingly healthy populations to act as ‘sources’ of new animals and genes for small, isolated populations.”



The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.&nbsp;

California mountain lions are not fully protected from humans

California mountain lions continue to be threatened by human activities,...

Pet technologies have reached new heights in sophistication and pet owners can now purchase gadgets that monitor their pet’s activities, food intake, calorie use, sleep hours and location. Some of the apps allow the owner to observe the pet, talk to it in order to comfort it in their absence, or even activate toys that entertain it through the day. However, these apps may have a hidden cost in terms of cybersecurity.



Computer scientists from <a href="https://www.ncl.ac.uk/">Newcastle University</a> and Royal Holloway, University of London, have evaluated the privacy and security status of 40 popular Android apps for pets, companion animals and farm animals. The team presented the <a href="http://dx.doi.org/10.1145/3567445.3571102">results</a> at the&nbsp;2022 IEEE European Symposium on Security and Privacy Workshops conference, and published them in the Proceedings of this conference.



The researchers found that many of these apps, designed to put the minds of pet owners at ease, also put their privacy and <a href="https://www.earth.com/news/tighter-school-security-linked-to-lower-test-scores/">security</a> at risk in various ways by exposing their login or location details. The apps relate to the use of smart gadgets as diverse as cameras, water and food dispensers, GPS trackers, wearable devices that track pet activity, and toys that can be activated remotely. There are also apps and platforms that allow owners to track and manage their pets’ health records and connect with veterinary professionals.



Scott Harper is a PhD student at Newcastle University’s School of Computing and the lead author of the study. “Pet tech such as smart collars and GPS trackers for your cat or dog, is a rapidly growing industry and it brings with it new security, privacy, and safety risks to the pet owners," said Harper. "While owners might use these apps for peace of mind about the health of their dog or where their cat is, they may not be happy to find out about the risks the apps hold for their own cybersecurity.”



Password vulnerability&nbsp;was one of the areas exposed by the team. They identified three applications that had the user's login details visible in plain text within non-secure HTTP traffic.&nbsp;This means that anyone is able to observe the internet traffic of someone using one of these apps and will also be able to find out their login information. In addition to login information, two of the apps also showed user details, such as their location, which may enable someone to gain access to the devices and mount a cyber-attack.



Another area of concern identified in the study was the&nbsp;use of trackers.&nbsp;All but four of the applications were found to feature some form of tracking software.&nbsp;A tracker gathers information on the person using the application, on how they use it, or on the smartphone being used.



The scientists also warn that the apps perform very poorly in terms of notifying the user of their privacy policy. Their analysis shows that 21 of the apps are tracking the user in some way before the user even has a chance to consent to this, which violates current data protection regulations.



“We would urge anyone using these apps to take the time to ensure they are using a unique password, check the settings and ensure that they consider how much data they are sharing or willing to share,” said Harper.



“We are using modern technologies to improve several aspects of our lives. However, some of these (often) cheap technologies come at the price of our privacy, security, and safety," said study co-author Dr. Maryam Mehrnezhad. "Animal technologies can create complex risks and harms that are not easy to recognize and address. In this interdisciplinary project, we are working on solutions to mitigate such risks and allow the animal owners to use such technologies without risk or fear.”



In a second, related study, the research team surveyed almost 600 pet owners from the UK, USA and Germany. They asked questions about the technologies used, the incidents that have occurred or that participants believe may occur, and the methods used by participants to protect their online security and privacy and whether they apply these to their pet tech.



The results show that participants do believe they are vulnerable to a range of attacks that may target their pet tech. Despite this, they take few precautions to protect themselves or their pets from the possible risks and harms of these technologies.



“We would urge those developing these technologies to increase the security of these devices and applications to reduce risk of their personal information or location being shared," said study co-author Dr. Matt Leach.



The researchers also urge those who are using pet tech to ensure they are using a unique password, check the settings, and consider what data they are sharing. &nbsp;Users should be cautious about any new IoT (Internet of Things) devices they bring into their homes. They should download apps associated with animal tech from known app stores and constantly check the permissions of such apps and revoke any unnecessary permission from them. Guides such as&nbsp;<a href="https://foundation.mozilla.org/en/privacynotincluded/">Mozilla's `*Privacy Not Included' project</a>&nbsp;are available to help inform consumers of the potential security and privacy risks.

Are our pets leaking information about us?

Pet technologies have reached new heights in sophistication and pet...

The latest <a href="https://www.ipcc.ch/">Intergovernmental Panel on Climate Change</a> (IPCC) report was released today, and the message is abundantly clear - climate action is urgently needed to keep our planet habitable. The message is also somewhat hopeful, as the experts say there are feasible and effective options to reduce greenhouse gas emissions and adapt to human-caused climate change that are available now.



Erin Coughlan de Perez, a lead author of one of the underlying analyses, says the IPCC report serves as a stark reminder that climate change is driving humanitarian crises and human suffering around the world.&nbsp;



"The window is closing, but the report also shows that it is not too late yet. It is time for the international community to take urgent action to reduce emissions to stay below the 1.5 degrees warming limit and work with communities to adapt and prepare for climate change impacts."



While the 1.5-degree target seemed like a major hurdle when the 2018 IPCC report was released, the challenge has become even greater over the last five years as heat-trapping greenhouse gas emissions have only increased. The experts say that the pace and scale of what has been done are insufficient to tackle climate change.



Climate warming is causing brutal weather extremes such as deadly storms and heatwaves, and these extremes will become much worse with every small increase in the average global temperature. The risks of food and water insecurity are also rising alongside temperatures.



The authors emphasize that the impacts of climate change are not evenly distributed, and the most vulnerable people are often hit the hardest. They say that urgent action is needed for a sustainable, equitable world.



“Climate justice is crucial because those who have contributed least to climate change are being disproportionately affected,” said Aditi Mukherji, one of the 93 authors of this Synthesis Report. “Almost half of the world’s population lives in regions that are highly vulnerable to climate change. In the last decade, deaths from floods, droughts and storms were 15 times higher in highly vulnerable regions."



According to the report, in order to limit global warming to 1.5°C, emissions will need to be cut by almost half by 2030. The experts say that accelerated action to adapt to climate change is essential to close the gap between existing adaptation and what is needed.&nbsp;



"What is interesting about this report is that we usually talk about different parts of the climate crisis separately - reducing emissions, adapting to save lives, or responding to losses and damages," said Coughlan de Perez.



"This report acknowledges that we need to do everything at once, and it gives a roadmap for how we can achieve this. That roadmap is not a simple one, where we just make a few minor changes and keep going with the status quo. Instead, it is a call to transformation - fundamentally altering society to achieve climate-resilient development."

IPCC: Climate action urgently needed to end human suffering

The link between obesity and severe Covid-19 infection may be explained by an underactive immune response, according to a study by scientists at the <a href="https://www.citiid.cam.ac.uk/">Cambridge Institute of Therapeutic Immunology and Infectious Disease</a> (CITIID) and Wellcome Sanger Institute. The researchers demonstrated that immune cells show a blunted inflammatory response in patients who are obese.&nbsp;



Nearly 6.9 million people have died from Covid-19, and <a href="https://www.earth.com/news/study-reveals-link-between-air-pollution-and-obesity/">obesity</a> is one of the major risk factors for severe infection. However, the underlying cause of the link between obesity and severe Covid has not been clear.&nbsp;



“During the pandemic, the majority of younger patients I saw on the COVID wards were obese. Given what we know about obesity, if you’d asked me why this was the case, I would have said that it was most likely due to excessive inflammation. What we found was the absolute opposite," explained Professor Menna Clatworthy.



The researchers analyzed blood and lung samples from 13 obese patients with severe cases of Covid that required mechanical ventilation. While studying the activity of cells in the samples, the experts discovered that the obese patients had underactive immune and inflammatory responses in their lungs.&nbsp;&nbsp;



“This was really surprising and unexpected," said Professor Clatworthy. "Across every cell type we looked at, we found that the genes responsible for the classical antiviral response were less active. They were completely muted.”



According to the researchers, the findings could have important implications both for the treatment of COVID-19 and in the design of clinical trials to test new treatments.



“What we’ve shown is that not all patients are the same, so we might need to tailor treatments," said study co-author Dr. Conway Morris. "Obese subjects might need less anti-inflammatory treatments and potentially more help for their immune system.”



The study is published in the <a href="http://dx.doi.org/10.1164/rccm.202204-0751OC">American Journal of Respiratory and Critical Care Medicine</a>.

On March 20, 2023, at 5:24 p.m. ET, <a href="https://www.earth.com/news/spring-finally-arrives-this-weekend/">spring</a> begins in the Northern Hemisphere, marked by the so-called spring, or vernal, equinox – which, along with the autumn equinox in September, is one of the two moments in the year when the sun is directly above the equator. With days becoming longer and the weather warmer, flowers and trees starting to bloom, and birds and butterflies migrating back northward along the path of the sun, this period is celebrated by many cultures as a time of renewal and rebirth.&nbsp;



The word “equinox” comes from Latin, through the juxtaposition of the terms aequus (equal) and nox (night), signifying that days and nights are equal in length. While for our ancestors, whose timekeeping was less precise than ours, days and nights did seem perfectly equal at this time of the year, today we know that in fact we actually get a bit more daylight than darkness at the equinox, particularly at higher latitudes, since it takes the sun longer to rise and set the closer we get to the poles.



According to the website&nbsp;<a href="https://earthsky.org/?p=106531#:~:text=The%20March%202021%20equinox%20happens,autumn%20in%20the%20Southern%20Hemisphere.">EarthSky</a>, for sky watchers equinoxes are a perfect time to orient themselves since they are the only two times a year the sun rises due east and sets due west everywhere on our planet. As they put it, the equinox is “a good day for finding east and west from your yard or other favorite site for watching the sky. Just go outside around sunset or sunrise and notice the location of the sun on the horizon with respect to familiar landmarks.” 



Moreover, in both hemispheres, the sun sets faster during the equinoxes, since it hits the horizon at the steepest possible angle from the Earth. By contrast, during the winter and summer solstices, the Earth’s tilt is the most extreme, and the sun sets more slowly.



Since thousands of years, people all over the world have celebrated the spring equinox. For instance, at the Mayan site&nbsp;Chichén Itzá in today’s Mexico, the massive pyramid El Castillo was aligned in such a way that a shadow outlining the form of a so-called “snake of light” (Kukulcán) descends the steps at the equinoxes, while in England, Druids and Wiccans used to gather at Stonehenge before dawn to welcome to return of spring.



Nowadays, many cultures around the world have special celebrations at the equinox, such as the Persian New Year - also known as Nauryz, Navruz, or Nowrouz (meaning “new day”) - when people honor new beginnings by welcoming the future and shedding away the past. While the Chinese are trying to stand an egg upright during the equinox – which, according to an old tradition, will bring them good luck - in Japan the Vernal Equinox Day is a public holiday, with people visiting family graves and holding family reunions, in celebration of both past and future.&nbsp;

Spring has arrived in the Northern Hemisphere

On March 20, 2023, at 5:24 p.m. ET, spring begins...

Recently, the <a href="https://www.sydney.edu.au/">University of Sydney</a> in Australia has signed a contract with <a href="https://www.endurosat.com/">EnduroSat</a>, a major provider of micro-satellites and other space services, in order to explore the possibility of <a href="https://www.earth.com/news/new-signals-identified-in-the-search-for-extraterrestrial-life/">extraterrestrial life</a>. The search will begin with our nearest neighbor star system, Alpha Centaury.&nbsp;



The mission is called TOLIMAN after the star’s ancient Arabic name and is funded by the&nbsp;<a href="https://breakthroughinitiatives.org/">Breakthrough Initiatives</a>, an organization in California searching for other habitable worlds in the universe. The experts will look for planets in the habitable zone around two Sun-like stars in the system (Alpha Centaury A and B), which are located only four light years away from Earth.



“That’s tantalizingly close to home. Astronomers have discovered thousands of exoplanets outside our own solar system but most are thousands of light years away and beyond our reach,” said mission leader Peter Tuthill, an astrophysicist at Sydney who helped develop the technology behind the groundbreaking James Webb Space Telescope. “Modern satellite technology will allow us to explore our celestial backyard and perhaps lay the groundwork for visionary future missions spanning the interstellar voids to the Centauri system.”



Since discovering exoplanets is a significant technological challenge, even for large telescopes, the experts are using state-of-the-art methods for developing a small space telescope capable of extremely fine measurements which needs to fit the telescope within a limited volume of 12 liters, while maintaining its mechanical and thermal stability with exquisite precision. To do this, they will use EnduroSat’s flight-proven MicroSat technology, which can download payload data at a speed of over 125 Mbps. If this mini-satellite will manage to discover any exoplanets in the Alpha Centaury, other instruments can be further employed to analyze their atmospheres and surface chemistry in order to search for signs of possible biospheres.



“We are exceptionally proud to partner in this mission. The challenges are enormous, and it will drive our engineering efforts to the extreme. The mission is a first-of-its-kind exploration science effort and will help open the doors for low-cost astronomy missions,” said Founder and CEO of EnduroSat Raycho Raychev.



“It’s very exciting to see this program come to life. With these partnerships, we can create a new kind of astronomical mission and make real progress on understanding the planetary systems right next door,” concluded Executive Director of Breakthrough Initiatives Pete Worden.

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



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.



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



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.



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



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.



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



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.



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



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, 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.



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.

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



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.



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



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.



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



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.



"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.



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



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.



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

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



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.



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



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.



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."



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



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.



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.



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



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, 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.

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



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.



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



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.



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



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.



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.



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



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.



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.



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

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.



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



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.



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.



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.



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.



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



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.



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.



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



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.



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.



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



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.



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.



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



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.



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



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



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.



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%.



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



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.



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.



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.

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



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.



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



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.



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.



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



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.



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



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.



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



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.



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">Nature Communications</a>.

<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>



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.



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



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.



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



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.



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



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.



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



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.



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



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.

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



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>.



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



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.



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



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.



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



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.



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.



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



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.



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.



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



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.



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



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>. This research offers renewed hope against cancer, and it can potentially open a door to more effective cancer therapies for most cancer patients worldwide.

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.



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.



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.



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.



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.

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



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.



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.



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



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.



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.



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.



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



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."



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



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.



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



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



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.



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.



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



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.



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.



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



The forest was remarkably diverse. Scientists identified Eospermatopteris, 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.



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.



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



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.



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."



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.



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



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.



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.



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



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.



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.



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.



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.



The full study was published in the journal Current Biology.

</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>



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.



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



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.



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."



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.



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



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.



"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.



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.



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



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.



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.



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



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.



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>.



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



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.



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.



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



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.



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.



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



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.



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.



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.

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>



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.



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



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 Neuron</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.



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.



"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.



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



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.



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.



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



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.



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.



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



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.



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.



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



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



Dr. Konstantina Kilteni's 2025 research, published in <a href="https://www.science.org/doi/10.1126/sciadv.adt0350" target="_blank" rel="noreferrer noopener">Science Advances</a>, 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.



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



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



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.



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.



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



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.



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.



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



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.



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



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



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.



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.



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

</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>



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.



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



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.



That solace came through H.G. Wells' The Time Machine. 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.



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



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.



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.



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.



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



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."



"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.



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



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."



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.



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



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



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



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 This American Life</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 Today Show</a>. The widespread interest reflects both his compelling personal story and rigorous scientific approach.



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



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.



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.



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.



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.



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



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."



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.



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.

</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>



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?



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.



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



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.



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



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.



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.



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



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.



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



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.



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.



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.



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



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.



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



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



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



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.



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



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.



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.



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



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.



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.



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



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



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



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.



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



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.



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



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.



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.



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



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.



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.



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



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.



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.



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.



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

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



1. Is acid rain completely gone? 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.



2. How long did solving take? 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.



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



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



5. Could acid rain return? 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.



6. Can you recommend any teaching tools on the subject of "acid rain"? 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>

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. 



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



<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">

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



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



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. 



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).



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



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.



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.



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>.

Today’s Video of the Day 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.



"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.



"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."

Today's Video of the Day 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.



"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.



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.

Today’s Video of the Day 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;



"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.



"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."



"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."

Today's Video of the Day 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;



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;



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.

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



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;



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;



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. 



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.



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.
