Strength training often brings to mind toned arms and powerful legs. But new research suggests that the benefits extend much further. Lifting weights may also reshape the trillions of microbes living in our gut, which influence everything from metabolism to immunity.



The <a href="https://www.earth.com/news/studies-learn-the-exact-amount-of-time-you-should-spend-training-to-build-muscle/">gut</a> microbiome is closely linked to both health and aging. Inside of it are microbes like Faecalibacterium, Akkermansia, and Roseburia hominis. These tiny organisms produce short-chain fatty acids that strengthen the gut lining and ease inflammation.



Endurance activities like running or cycling are known to boost these helpful microbes. But when it comes to resistance training, the picture has remained far less clear.



<h2 class="wp-block-heading" id="h-conflicting-past-studies">Conflicting past studies</h2>



Until recently, research painted a mixed picture. Some trials found that weight training shifted microbial communities, while others reported almost no changes. 



Matthieu Clauss of the <a href="https://www.nih.no/english/" target="_blank" rel="noreferrer noopener">Norwegian School of Sport Sciences</a> in Oslo noted that the existing research remains limited.



To settle this uncertainty, Sven Nahnsen and colleagues at the <a href="https://uni-tuebingen.de/en/" target="_blank" rel="noreferrer noopener">University of Tübingen</a> studied 150 sedentary adults. Participants engaged in an eight-week resistance program using advanced machines that adjusted loads in real time and tracked every lift.



<h2 class="wp-block-heading" id="h-tracking-strength-and-gut-microbes">Tracking strength and gut microbes</h2>



This digital system created detailed performance records while ensuring progressive, individualized training. Stool samples collected before, during, and after the program allowed researchers to map microbial changes.



When researchers looked at the whole group, they saw no clear changes in microbial diversity. The story shifted, however, once strength gains came into focus. 



Participants who made the biggest improvements showed noticeable rises in Faecalibacterium and Roseburia hominis. In fact, these microbes were especially abundant in individuals who gained far more <a href="https://www.earth.com/news/strength-training-may-be-the-best-exercise-for-insomnia/">strength</a> than everyone else.



<h2 class="wp-block-heading" id="h-microbes-differ-in-strong-lifters">Microbes differ in strong lifters</h2>



The study revealed clear differences between high and low responders. The strongest gains were linked with distinct changes in <a href="https://www.earth.com/news/natures-sweet-remedy-honey-is-a-microbial-marvel/">microbial</a> composition.



High performers also showed enrichment of members of the Lachnospiraceae family, many of which are linked to anti-inflammatory effects.



Notably, an amplicon sequence variant classified as Roseburia hominis showed the most significant increase in high responders by week eight.



Other enriched microbes included Bacteroides massiliensis and certain Prevotellaceae. Meanwhile, taxa like Lachnoclostridium and Oscillospiraceae declined.



<h2 class="wp-block-heading" id="h-gut-shifts-depend-on-training-progress">Gut shifts depend on training progress</h2>



Why do only some people experience these changes? <a href="https://www.earth.com/news/weight-training-shields-the-aging-brain-from-dementia/">Training</a> compliance was similar, and diet surveys showed no clear differences. 



This suggests factors beyond effort or food intake. One possibility is that microbial shifts themselves supported muscle gains by increasing production of short-chain fatty acids, which enhance energy metabolism and recovery.



Resistance training did not increase overall microbial richness (alpha diversity), unlike endurance training, but it did remodel microbial composition (beta diversity) in high responders. 



This points to a dose-response effect: only when strength improvements cross a certain threshold do microbiome shifts emerge.



<h2 class="wp-block-heading" id="h-lifting-and-running-converge">Lifting and running converge</h2>



Despite differences between <a href="https://www.earth.com/news/why-running-can-help-you-move-think-and-feel-better/">running</a> and lifting, both exercise types seem to converge on similar microbial outcomes. 



Enriched short-chain fatty acid producers like Faecalibacterium and Roseburia suggest common pathways that support gut integrity, regulate glucose, and reduce systemic inflammation.



The changes occurred without dietary modification, meaning resistance training alone can act as a driver of gut remodeling. This highlights its role not only for musculoskeletal health but also for metabolic and immune regulation.



<h2 class="wp-block-heading" id="h-exercise-benefits-are-clear">Exercise benefits are clear</h2>



Some mysteries remain. Stool metabolomics showed no significant changes, which may indicate that functional shifts were subtle, localized, or required longer adaptation. 



The study also lacked a non-exercising control group, leaving room for further confirmation.



Even so, outside experts remain hopeful. The results suggest that <a href="https://www.earth.com/news/exercise-reduces-depression-and-anxiety-in-children-and-teens-with-mental-health-issues/">exercise</a> of any kind can benefit gut health. They also point to the possibility that resistance training sparks unique, health-related shifts in the microbiome.



<h2 class="wp-block-heading" id="h-strength-training-as-gut-medicine">Strength training as gut medicine</h2>



From a public health perspective, resistance training may offer far more than toned muscles. It could serve as a non-drug approach to improving gut health, especially for people facing chronic inflammation or the challenges of aging.



The changes happening inside the gut are striking. Beneficial microbes increase, the gut lining becomes stronger, and <a href="https://www.earth.com/news/fasting-helps-the-body-fight-inflammation-and-chronic-diseases/">inflammation</a> settles down. These microbes also help regulate blood sugar and energy use, lowering the risk of long-term conditions such as diabetes, heart disease, and digestive problems.



What makes this especially interesting is that participants did not need to change their diets. The exercise itself appeared to reshape the gut community, suggesting that strength training works as its own form of medicine.



For many, this shifts how we think about working out. Exercise is not only about muscles or appearance - it is about keeping the body resilient from within. Regular resistance training might help people recover faster, age more gracefully, and carry less risk of disease throughout life.



The study is published in the journal <a href="https://www.biorxiv.org/content/10.1101/2025.08.13.670057v1" target="_blank" rel="noreferrer noopener">bioRxiv</a>.

Strength training can boost healthy gut bacteria

Strength training often brings to mind toned arms and powerful legs. But new research suggests that the benefits extend much further. Lifting weights may also reshape the trillions of microbes living in our gut, which influence everything from metabolism to immunity. The gut microbiome is closely linked to both health and aging.

New LED Technology Could Reduce Greenhouse Gas <a href="https://www.bing.com/search?q=emissions&amp;cvid=ca0ef38668c24fff9bbf018c8dae5c21&amp;FORM=ANAB01&amp;PC=HCTS">Emissions</a>. Highly efficient, light-emitting diodes -- LEDs -- could slash the world's electricity consumption. They are already sold in stores, but more widespread adoption of the <a href="http://www.earth.com/news/new-technology-transforms-paper-into-an-electronic-device/">technology</a> has been hindered by high costs due to limited availability of raw materials and difficulties in achieving acceptable light quality. But researchers will report today that they have overcome these obstacles and have developed a less expensive, more sustainable white LED.

The scientists will discuss their research at the 250th National Meeting &amp; Exposition of the American Chemical Society (ACS). ACS is the world's largest scientific society. The national meeting, which takes place here through Thursday, features more than 9,000 presentations on a wide range of science topics.New LED Technology Could Reduce Greenhouse Gas Emissions

"If more people in the U.S. used LEDs in their homes and businesses, the country's electricity consumption could be cut in half," says Zhichao Hu, Ph.D., a member of the Rutgers University team that performed the research under the direction of Jing Li, Ph.D. At that time, he was a graduate student. He is now a postdoc at Rutgers and is studying the recovery of rare-earth elements there. Zhichao adds that studies show substituting one LED light for a common incandescent light bulb in every American household could save the nation $700 million annually in energy costs.

To achieve the common, soft white light that consumers expect, current LED technologies typically use a single semiconductor chip to produce light, usually blue, and then rely on a yellow-emitting "phosphor" coating to shift the color to white. That's because LEDs do not emit a white light. The phosphor is made from materials, such as cerium-doped yttrium aluminum garnet, that are composed of rare-earth elements. These elements are expensive and in limited supply, since they are primarily available only from mining operations outside the U.S. Additionally, the light output of these phosphors tends to be harsh, "cold" colors.

Li's team is developing hybrid phosphor-based technologies that are much more sustainable, efficient and low-cost. They combine common, earth-abundant metals with organic luminescent molecules to produce phosphors that emit a controllable white light from LEDs. By varying the metal and organic components, the researchers can systematically tune the color of the phosphors to regions of the visible light spectrum that are most acceptable to the human eye, Hu and Li note. The team is continuing to experiment and develop other rare-earth-free LED phosphors based on different metals and organic compounds.

Many material combinations are possible, so they use a computational approach to initially sort through the possibilities and to predict what color of light the various metals and organics combinations will emit. They then test the best combinations experimentally.

Their approach allows a systematic fine tuning of band gaps and optical emissions that cover the entire visible range, including yellow and white colors. As a result, their LEDs can be fine-tuned to create a warmer white light, similar to cheaper but inefficient incandescent lights. Their approach shows significant promise for use in general lighting applications.

"One of challenges we had to overcome was to figure out the right conditions to synthesize the compound," Hu notes. "Like cooking, the synthesis requires a 'recipe.' It's often not the case that one can simply mix the starting materials together and get the desired product. We optimized the reaction conditions -- temperature and the addition of a solvent -- and developed an easy procedure to make the compound with high yield."

Experiments with some materials have shown that the team's technology can cut LED costs by as much as 90 percent from current methods that rely on rare-earth elements. They have several granted and pending U.S. patents and are exploring manufacturing possibilities.

Poll: Few Catholics Know Pope's Stance On Curbing Climate Change. A new survey has found fewer than half of U.S. Roman Catholics said they knew of Pope Francis' bombshell encyclical on curbing climate change - and only a fraction of those heard about it from the pulpit - in the month after he released the document with an unprecedented call for the church to take up his message.
Forty percent of American Catholics and 31 percent of all adults said they were aware of the encyclical, according to the poll by The Associated Press-NORC Center for Public Affairs Research and Yale University. Among Catholics who knew about the document, just 23 percent said they heard about it at Mass.Poll: Few Catholics Know Pope's Stance On Curbing Climate Change
The survey, conducted July 17-19, provides an early measure of the impact of the encyclical in the U.S., where Francis is expected to press his teaching on the environment in his first visit to the country next month.
The U.S. is home to some of the staunchest objectors to mainstream science on climate change and to government intervention aimed at easing global warming, along with a segment of Catholics who think the pope should be talking far more about marriage and abortion than the environment.
In the encyclical, released June 18, Francis called global warming a largely manmade problem driven by overconsumption, a "structurally perverse" world economic system and an unfettered pursuit of profit that exploited the poor and risked turning the Earth into an "immense pile of filth." He urged people of all faiths and no faith to save God's creation for future generations.
Environmental advocates hoped the encyclical would transform public discussion of climate change from a scientific to a moral issue. But Catholics in the survey were not significantly more likely than Americans in general to think of global warming in moral terms. Just 43 percent of Catholics and 39 percent of all adults said they considered global warming a moral issue. A very small percentage viewed climate change as having a connection to religion or poverty.
"That's unfortunate," said Dan Misleh, executive director of the Catholic Climate Covenant, which works closely with the U.S. bishops on environmental protection and has distributed model sermons and parish bulletin inserts on the encyclical. "There's a clear human impact. That's going to be our challenge - to explain that this environmental question is really a human thriving question."
The document had a rollout unlike any other. The encyclical was introduced at the Vatican by a secular climate scientist and a top Orthodox Christian leader, with simultaneous news conferences by Catholic leaders in many countries and the chiming of church bells for emphasis. Francis underscored the importance of the document by sending it to the world's bishops with a handwritten note.
But questions arose about whether American bishops and parishioners would embrace the message with any enthusiasm. While the bishops for decades have issued statements calling environmental protection a religious duty for Catholics, the issue has not been atop their public agenda.
For years, the U.S. Conference of Catholic Bishops has focused its resources on upholding marriage as the union of a man and a woman, seeking religious exemptions from laws the bishops consider immoral, fighting abortion and clergy sex abuse, and bringing back fallen-away Catholics.
This summer, bishops in Iowa, Illinois and Ohio have held news conferences on the encyclical, urging political leaders to take up the pope's call for bold leadership and pledging to reduce carbon emissions or water and power usage in their own dioceses.
In California, the Diocese of Orange held an Aug. 8 conference on the theology of the encyclical and the science of climate change, drawing 450 attendees and an additional 500 viewers via livestream, a spokesman said. And Miami Archbishop Thomas Wenski, the U.S. bishops' point person on the environment, has cited the encyclical in expressing support for President Barack Obama's clean power plant rules announced this month.
But Terry Majewski, 67, a Pensacola, Florida, resident who said he attends Mass weekly, said he has heard no preaching about the encyclical at his local church. He's glad he hasn't. Majewski thinks highly of the pope, but disagrees with his position on global warming and wishes the pontiff hadn't taken up the issue. In the survey, about two-thirds of Catholics said it was appropriate for Francis to take a position on global warming, and 55 percent of all adults agreed.
"He can talk about his own belief, but don't sit there and bring it down on the church," Majewski said, adding Francis should talk about "things that relate to religion, not climate change."
At St. Camillus Catholic Church in Silver Spring, Maryland, last weekend, about 1,000 of the estimated 4,800 people who usually attend Masses there signed a petition urging immediate action to curb carbon emissions, said the Rev. Jacek Orzechowski. He said it was a sign that interest in the pope's statement and in climate change is "percolating" among Catholics, despite the survey findings.
"I think it's beginning to take root within the parishes within the archdiocese," Orzechowski said. "One can be dissatisfied it has not produced more fruit, but the seeds are germinating."
Francis is widely expected to reiterate his plea for bold policy measures on global warming when he travels to the U.S., where he will address a joint meeting of Congress on Sept. 24 and the U.N. General Assembly the next day.
Climate change activists had hoped Francis' rock-star popularity would amplify his views. But a recent Gallup poll found double-digit drops in his favorability, fueled mainly by conservatives who think he has gone too far with his reforms and statements, and liberals who believe he hasn't gone far enough.
The AP-NORC poll found 62 percent of Catholics and 39 percent of Americans overall had a somewhat or very favorable view of Francis. One-third of Catholics and nearly half of all adults said they didn't know enough about the pope to form an opinion.
In the survey, Catholics held views of global warming in line with the general public. About three-quarters of Catholics and 69 percent of all adults said global warming is happening. About half of both groups say climate change is mostly or entirely man-made, while 46 percent of Catholics and 38 percent of all adults blame a mix of human activity and natural changes in the environment.
The AP-NORC poll of 1,030 adults was conducted using a sample drawn from NORC's probability-based AmeriSpeak panel, which is designed to be representative of the U.S. population. The margin of sampling error for all respondents is plus or minus 4.4 percentage points, and larger for subgroups. Respondents were first selected randomly using address-based sampling methods, and later interviewed online. People selected for AmeriSpeak who didn't otherwise have access to the Internet were interviewed over the phone.

Warming Temperatures Are Forcing Eastern Brook Trout To Relocate. When trying to explain the potential effects of climate change on plants, fish and wildlife, scientists usually resort to language that fails to convey the impact of warming. Now, a study by Penn State's College of <a href="http://www.earth.com/news/climate-smart-agricultural-practices-will-boost-global-food-security/">Agricultural</a> Sciences fisheries researchers clearly explains the impact of projected warming waters on wild brook trout in the eastern U.S. for fishermen.

The eastern brook trout is a socially and economically important fish that occurs in small cold water streams and lakes, and self-sustaining populations support angling throughout the Appalachian Mountains, from Maine to Georgia. However, warming air temperatures are expected to reduce available cold-water habitat and result in a smaller brook trout distribution and fewer angling opportunities.Warming Temperatures Are Forcing Eastern Brook Trout To Relocate

Building on recent research at Penn State, Tyler Wagner, adjunct professor of fisheries and Tyrell DeWeber, now a postdoctoral scholar at <a href="https://www.bing.com/search?q=oregon&amp;cvid=593c3a59910343438ec4024e80ddd9c7&amp;FORM=ANAB01&amp;PC=HCTS">Oregon</a> State University, used two models they previously developed, one predicting stream temperature and one predicting where brook trout might occur, to identify streams likely to support wild brook trout under current and future climate scenarios.

The researchers then calculated the distance required to drive from the centers of 23 cities spread throughout the eastern brook trout range to the 10 nearest stream segments likely to have wild brook trout under current and future conditions. They published their study in a recent issue of Fisheries.

"Climate change is expected to result in widespread changes in species distributions for freshwater fish species. Although anglers and other resource users could be greatly affected by these predicted changes, changes are rarely reported in ways that can be easily understood by the general public," said Wagner, who is assistant unit leader of the Pennsylvania Cooperative Fish and Wildlife Research Unit at Penn State.

The effects of climate change on fish and wildlife are usually reported to the general public using summary metrics or maps designed to communicate concepts that are not normally encountered in everyday life, including changes in habitat suitability, range shifts, or increasing risks from disease or extreme events, according to Wagner. "Though these metrics are necessary, meaningful, and understood by scientists, many people lack the necessary training and background to readily understand them."

"Further, scientists and nonscientists alike may struggle to convert these metrics into a currency that directly affects day-to-day life. Climate science is a complex issue, and when we communicate potential responses of vegetation, fish and wildlife to nonscientists, creative thinking with respect to the currency of communication will facilitate discussions between scientists, policy makers and the public."

DeWeber, who was a doctoral student at Penn State when the research was conducted, noted that travel costs based on distance have been widely used to value ecosystem services such as angling under climate-change scenarios, but have not been used for communicating potential changes to the public, despite the intrinsic link to everyday life.

"Under current conditions, brook trout are predicted to occur in streams throughout the region, and average driving distances from cities to the nearest streams predicted to offer angling opportunities ranged from 4 to 87 miles. As a result of projected warming, driving distance to go fishing for wild brook trout was predicted to increase, on average, by almost 164 miles over the next 70 to 80 years."

For example, the driving route from Philadelphia to the nearest brook trout stream was predicted to cover 249 miles in a warmer future, much longer than the current 48 miles.

The lengths of trips from many northern cities, such as Bangor, Maine, were predicted to increase but were still relatively short in the future because nearby streams were still predicted to support brook trout under warmer conditions.

In contrast, anglers in southern cities, such as Cleveland, Tennessee, would experience dramatic increases in the lengths of trips because brook trout are predicted to be lost in surrounding areas.

Although anglers tend to be very dedicated, DeWeber pointed out, it is unlikely that many would drive great distances to fish very often due to cost, especially if those last remaining streams become popular and crowded. He believes that losses of wild brook trout populations and increased trip lengths would likely result in reduced resource use in many areas.

But he suggested that people are unlikely to be concerned about the potential effects of warming if they do not understand what may be coming. "Communicating species responses to climate change in everyday language could greatly increase the ability of resource users and other members of the general public to understand and relate to predicted changes," he said. "A clear understanding of potential changes might not lead to greater societal concern about species' responses, but it may enable people to make informed decisions."

"I've literally trained when there's ash falling on me, where they say `Do not go outside,'" said Lieberg, a 36-year-old from Helena. "My lungs are definitely ready."
Seven years after the Olympics sparked talk of a dramatic clean-up of heavy air pollution in Beijing, a milky haze still covers the city on most days and is expected to be there when the marathons take place - Saturday for the men, and Aug. 30 for the women.
According to a recent study conducted by physicists at the University of California, Berkeley, 1.6 million people die each year in China from heart, lung and stroke-related problems due to polluted air. The statistic is a reminder that while the Olympics may serve to shed light on a host city's environmental problems, they don't necessarily solve them.
With the 2022 Winter Olympics set to also take place in Beijing, the environment is likely to stay in the spotlight, in part because of plans to bring tons of artificial snow to the relatively dry mountains outside Beijing.
It's as true for Rio de Janeiro today as it was for Beijing in 2008, Athens in 2004, Sydney in 2000 or almost any other host, all of which have had their problems with air and/or water, said John Karamichas, author of the 2013 book "The Olympic Games and the Environment."
"All these issues were, in one way or another, addressed for the duration of the games," Karamichas said. "Environmental legacy will depend on the post-event political processes."
An expert from the World Health Organization, Martin Taylor, said government figures have shown some improvements in Beijing's air quality since the Olympics left town "but there is still some way to go before (it) meets international safe standards."
Competition conditions for the Olympic athletes have been at the forefront recently with the Rio Games less than a year away.
An analysis commissioned by The Associated Press found viruses running rampant in Rio's sewage-strewn water. The International Olympic Committee has made no plans to test for viruses, sticking with a plan to only monitor bacteria. Some swimmers have fallen ill after competing in the water, though the direct correlation between the water and the illness is difficult to make.
Running in heavily polluted air carries some health risk because of particulates that can clog up passageways and increased ozone that mainly bothers people with asthma. It can also affect finely tuned athletes who operate at maximum lung capacity. In 2008, the marathon world record holder, asthma sufferer Haile Gebrselassie, said he wouldn't run the race. "The pollution in China is a threat to my health," he said.
But he was an exception. And even though pollution readings distributed by the U.S. Embassy's Beijing Air Quality Monitor frequently shows the air quality in the "unhealthy" range, the races at world championships will go on.
Questions about if runners should wear masks for competition are resurfacing. Scientists think that would produce, at best, mixed results. The masks do filter out particulates but most elite runners are creatures of habit and not used to wearing them. Distance runner Galen Rupp won U.S. championships wearing a mask in 2011, but he had trained extensively with it, and it was used to filter out pollen, not pollution.
"One can't with a straight face say that it doesn't do anything," said Dr. Sverre Vedal, a health science professor at the University of Washington. "But one of the issues that comes up is the practicality of wearing a mask if you're performing."
Last October, the Beijing Marathon began with thousands of participants wearing masks. The air quality reading that day was considered hazardous, and a level at which the U.S. Embassy says everyone should avoid all outdoor exertion.
Big events such as the Olympics and world championships put authorities on timelines to mitigate the problems, at least temporarily.
For the track meet, local organizers are following a model nicknamed "APEC Blue" - a Chinese government program that produced blue skies last November for the Asia-Pacific Economic Cooperation summit.
This approach calls on nearby provinces to cut down on the amount of pollution drifting in from factories outside the city limits. Officials also will restrict the number of cars on the streets of Beijing starting Thursday, two days before the world championships begin. They took half the cars off the road each day starting a few weeks before the Olympics.
A handful of athletes the AP interviewed said they're heading to Beijing knowing they can't do much about the pollution.
"I'm running for only 12 seconds," American hurdler David Oliver said. "Now, if I were a marathoner, maybe I'd pay more attention."

Study: Dying Wildlife And Bigger Fires If Drought Continues. The carcasses of salmon, trout and more than a dozen other newly extinct native species lie in dry streambeds around California.
Exhausted firefighters in the Sierra Nevada battle some of the biggest wildfires they've ever seen. And in Central Valley farm towns, more and more mothers hear the squeal of empty pipes when they turn on water taps to cook dinner.Study: Dying Wildlife And Bigger Fires If Drought Continues
A new report by the Public Policy Institute of California non-profit think-tank paints that distressing picture of California for the next two years if the state's driest four years on record stretches further into the future.
Written by water and watershed experts working at the policy center, at the University of California, Davis, and elsewhere, the report urges California to do more now to deal with what researchers project to be the biggest drought crises of 2016 and 2017 - crashing wildlife populations, raging wildfires and more and more poor <a href="http://www.earth.com/news/rising-suicide-rates-rural-counties/">rural</a> communities running out of water entirely.
So far, of all the sectors dealing with the drought, <a href="https://www.bing.com/search?q=california&amp;cvid=959b5795b215418bb2b813f28e952351&amp;FORM=ANAB01&amp;PC=HCTS">California</a> cities are doing relatively well thanks to the lessons of past droughts, the report concludes. Meanwhile, farms have been able to turn to pumping well water to make up for having half as much surface water for irrigation as normal.
With California wildlife, by contrast, "we're really looking at widespread crisis" if the drought continues, Ellen Hanak, director of the think-tank's water policy center, said in an interview Wednesday.
California's fresh-water habitats and forests, along with their wildlife, have experienced the most severe impacts of the drought so far, the study concluded.
Lack of water means 18 species of native California fish, including most native salmon and steelhead trout, face an immediate threat of going extinct in the wild, the report said.
Greatly reduced water deliveries to bird refuges and rice fields - the flooding of which provides crucial habitat - means there is dangerously little room and food for the 5 million migratory birds that fly through the Central Valley each year and a high risk of deadly disease for the birds, the study said.
For California's environment, officials should be thinking more strategically about how best to use what water is left for wildlife, and preparing "conservation hatcheries" to safeguard native fish species that are on the verge of extinction in the wild, it said.
Hanak also called wildfires a tremendous risk as overgrown forests dry in the drought. Fire and forest agencies already are working to reduce the overgrowth that contributes to making those fires bigger and harder to control, researchers said.
After the environment, rural communities have been hardest-hit by the drought, the study said. As of last month, more than 2,000 domestic wells were reported to have gone dry, mostly in the Central Valley and Sierra Nevada. More than 100 small public-water systems around the state have been cited as needing emergency water supplies.California's fresh-water habitats and forests, along with their wildlife, have experienced the most severe impacts of the drought so far
State and federal efforts to help those communities have been increasing but remain stop-gap, the study concluded. It urges the state to do more to track areas in need of help and come up with longer-term water supplies to replace wells that have likely gone dry for good.

BP Oil Spill Settlement Money Found In Strange Places. Clusters of landlocked municipalities more than 100 miles from the Gulf Coast have secured millions of dollars in BP money through settlements designed to compensate local governments for lost tourism dollars and other economic damage from the company's 2010 oil spill, according to records obtained by The Associated Press.
This week, BP finished making approximately $687.4 million in settlement payments to 383 local government entities in the five Gulf states. Nearly $8 million of that money went to 32 government entities that are more than 100 miles from the coast, in places like the<a href="https://www.bing.com/search?q=mississippi&amp;cvid=a6dd128c0c76464cb2b2849ff061a493&amp;FORM=ANAB01&amp;PC=HCTS"> Mississippi</a> Delta and suburbs of central Alabama, the records show.BP Oil Spill Settlement Money Found In Strange Places
BP's well blowout off Louisiana's coast triggered a deadly explosion that killed 11 rig workers and spewed millions of gallons of oil into the Gulf of Mexico, staining beaches, killing wildlife and scaring away tourists.
The company agreed last month to pay up to $1 billion to resolve economic claims by local governments, but the settlement payouts have fallen well short of that maximum amount. The records obtained by the AP provide the most comprehensive accounting of where the money went and what types of government entities received shares.
The AP analyzed minimum distances from the center point of each city or town to the coastline to determine which locations were farther than 100 miles away from the coast.
Jackson, Mississippi, approximately 175 miles from the coast, received $1.3 million. Birmingham, Alabama, more than 200 miles from the coast, received $1 million.
Among the smaller cities receiving money is Ruleville, a Mississippi Delta city that landed $40,748. Ruleville, which is nearly 300 miles from the coast and has about 3,000 residents, said it lost revenue from sales taxes and other sources due to a drop in tourist travel after the spill. The city, perhaps best known as the hometown of civil rights activist Fannie Lou Hamer, is in an area that is a popular destination for blues music fans.
"Everybody in Mississippi suffered to varying degrees," said Danny Griffith, Ruleville's city attorney.
Irondale Mayor Tommy Joe Alexander - whose city in the <a href="http://www.earth.com/news/drinking-cocoa-can-make-your-brain-sharper-and-faster/">Birmingham</a> suburbs received a $57,225 settlement award - said a seafood shortage after BP's spill led to a decrease in sales tax generated by local restaurants.
"We're very fortunate that we did get something," he said. "There was an impact on the whole state."
BP's settlements with local governments are part of its broader $18.7 billion agreement with the five Gulf Coast states and the federal government. Larger portions of settlement money are dedicated to coastal restoration work. BP already has paid billions of dollars in compensation to Gulf Coast businesses and residents who claim the spill cost them money.
July 15 was the deadline for local governments to decide whether to accept the settlement offer, which could not be renegotiated. BP, which couldn't veto individual payments, accepted the package of settlements on July 27.
A modest "windfall" for several communities far from the coast must have been an afterthought for BP given the broader deal's high stakes, according to Ed Sherman, a Tulane University Law School professor emeritus and expert in complex litigation.
"It's not a great deal of money when you consider the total amount of the settlement," Sherman said.
Only a handful of local governments have publicly announced that they rejected a settlement offer. They are free to continue pursuing their claims, but may have to wait for a trial date if BP is unwilling to negotiate a separate deal.
Many local governments that sued BP over the spill enlisted help from private attorneys who handled their claims on a contingency basis, typically in exchange for at least 20 percent of the settlement amount.
Ike Gulas, an attorney who filed claims for several government entities in the Birmingham area, said officials from other local communities contacted him after the settlement was announced last month and were disappointed to learn it was too late to file their own claims.
"A lot of lawyers looked at it and didn't think there was a claim there, but we did," Gulas said.
Many communities sought significantly more than what they ultimately accepted. Bessemer, another Birmingham suburb, accepted a $310,392 settlement, even though city attorney Shan Paden said independent accountants pegged Bessemer's spill-related losses at roughly $590,000.
"The timing was bad," Paden said of the spill. "The general economy was in bad shape. We can show objectively that the revenues were down for that period of time."
The federal judge overseeing most of the spill-related litigation against BP appointed a panel of neutral parties, including former FBI director Louis Freeh and Lafayette-based attorney Patrick Juneau, to determine the amounts of each settlement offer. The formulas and criteria used by the panel members have not been publicly disclosed.
The panel made offers to each local government that met certain legal requirements. To qualify, each government entity had to formally present its Oil Pollution Act claim to BP and either file a lawsuit or submit a two-page claim form directly to the federal court in New Orleans.
The $687.4 million in payments doesn't include awards to local governments that resolved their BP claims before the broader settlement was announced on July 2.
Nearly $371 million - more than half of the total settlement money - was awarded to local governments in Louisiana. Approximately $210 million is going to local governments in Florida, where the tourism industry cratered in the spill's aftermath even though few places in the state ever felt any direct impact from BP's oil. Local governments in Texas are getting $39.9 million, while those in Mississippi are receiving $37.3 million. Local governments in Alabama are getting $28.8 million.
The bulk of the settlement money - which was paid by BP in lump sums and can be spent on anything - is going to city and county or parish governments along the coast. Nearly $157 million, almost one quarter of the total, is going to more than 50 public school districts. Law-enforcement agencies are receiving around $21 million. Airports are getting nearly $15 million. About $6 million is going to hospitals.
William Husfelt, schools superintendent in Bay County, Florida, said the spill led to losses in property and sales tax revenues that fund public schools across the state.
"It was a terrible time for it to happen. It was right after the recession," he said. "The budgets were cut. Pay raises were flat."
Henry Kelley, a spokesman for the Okaloosa County, Florida, public schools, said the school board hadn't yet decided how to use its $2 million settlement award.
"We're not flush with cash. If spent properly, this will make a big impact," he said.

This story has been corrected to indicate that 32 recipients, not 33, are more than 100 miles away from the coast, and that the amount of money going to those entities is nearly $8 million instead of nearly $8.2 million.

Western Wildfires Burning Unchecked Due To Lack Of Firefighters. This summer's massive western wildfires have strained resources to the point that<a href="https://www.bing.com/search?q=wildfire&amp;cvid=3d1e2b511a104aeaa6d8b0656bf735b0&amp;FORM=ANAB01&amp;PC=HCTS"> wildfire</a> managers are being forced to let some fires burn unchecked, and that has renewed a longstanding debate about whether it is better to fight a fire - or to sometimes just let it burn out.
Drought and heat have combined to make this one of the most active fire seasons in the Lower 48 in recent years. Nearly 29,000 firefighters are battling some 100 large blazes across the West, but it hasn't been enough. In northern Idaho, private citizens have even jumped on fire lines to help overwhelmed firefighters. Western Wildfires Burning Unchecked Due To Lack Of Firefighters
"What we're getting now are much more intense fires because of all those years of suppression," said John Freemuth, a Boise State University professor and a public lands expert. "Those kinds of intense fires are usually not allowed to burn."
But fire managers have little choice this year.
Some 11,000 square miles have burned so far. Most of that has been in Alaska, but an increase in fires in the Idaho, Oregon, Montana, Washington and California has caused competition for firefighting resources with some requests going unmet.
Some fires have simply been unstoppable. Steve Ellis, deputy director of the U.S. Bureau of Land Management, earlier this week flew over a 443-square-mile rangeland fire in southwest Idaho and said he could see where retardant bombers put in lines that the fire easily crossed.
"It's always tough when we get to this point where we have much more fire than we have resources," said John Segar, one of eight members on an interagency group based in Boise that decides how to deploy the nation's wildland firefighters. "The decisions are essentially triage decisions."
Segar, chief of Fire Management for the U.S. Fish and Wildlife Service, sits on the National Multi-Agency Coordination Group at the National Interagency Fire Center.
While there's been a longstanding debate about whether it's better to fight a fire or just let it burn out, Sager said conditions are so volatile right now that every current fire or new fire start is being attacked with the intent of putting it out if resources are available.
"It's just been too dry and too hot," he said. Letting fires burn "really hasn't been a consideration this year."
Freemuth said land managers have moved toward recognizing using fire as a tool to reduce fuels that lead to intense fires, particularly after the giant fires in Yellowstone National Park in the late 1980s.
"Having fire on the landscape in the right conditions has been accepted management now," Freemuth said.
But efforts to reduce the threat of fires have been hampered by a lack of money for prescribed burns or work to clear brush.
Some Western lawmakers, including Republican Sens. Mike Crapo and Jim Risch of Idaho and Democratic Sen. Ron Wyden of Oregon, have been pushing for letting firefighting agencies use dollars meant for natural disasters. Currently, agencies have been dipping into money set aside for fire prevention, such as prescribed burns.
"It's sort of an East-West issue where other members of Congress and other parts of the country don't get it because they don't see these kinds of fires," Freemuth said.
Even some <a href="http://www.earth.com/news/scientists-track-endangered-green-turtles-in-western-australia/">Western</a> residents don't want to allow beneficial fires to burn because of the smoke, he noted. "It's like two environmental values having to be reconciled - the need for the right kind of fire and the need for good air quality."
Arguments have also been made for decades that more logging to remove trees and grazing by livestock to mow down grasses could remove fuels that would otherwise burn.
"Those can be legitimate tools," Freemuth said. "But that gets to the question of what's the purpose of our federal lands. Other people are going to say the No. 1 purpose should be ecosystem health."
Segar said the fires this year will likely burn until a season-ending weather event with rain or snow arrives, which could be weeks.
"We have so much fire on the ground we don't have enough people to put them out," he said. "They'll go out at the end of the season."

July Was The Hottest Month Ever Recorded On Earth. Earth just keeps getting hotter. July was the planet's hottest month on record, smashing old marks, U.S. weather officials said.
And it's almost a dead certain lock that this year will beat last year as the warmest year on record, they said.
July's average temperature was 61.86 degrees <a href="http://www.earth.com/news/babbler-birds-are-shifting-their-behavior-in-the-wrong-direction/">Fahrenheit</a>, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree, according to figures released Thursday by the National Oceanic and Atmospheric Administration. That's a large margin for weather records, with previous monthly heat records broken by a 20th of a degree or less.
"It just reaffirms what we already know: that the Earth is warming," said NOAA climate scientist Jake Crouch. "The warming is accelerating and we're really seeing it this year."
NOAA records go back to 1880. Separate calculations by NASA and the Japanese weather agency also found July 2015 to be a record.
The first seven months of 2015 were the hottest January-to-July span on record, according to NOAA. The seven-month average temperature of 58.43 degrees is 1.53 degrees warmer than the 20th-century average and a sixth of a degree warmer than the old record set in 2010.
Given that the temperatures have already been so high already - especially the oceans, which are slow to cool - NOAA climate scientist Jessica Blunden said she is "99 percent certain" that 2015 will be the hottest on record for the globe. The oceans would have to cool dramatically to prevent it, and they are trending warmer, not cooler, she said.
Crouch, Blunden and other scientists outside of the government said these temperatures are caused by a combination of man-made climate change and a strong, near-record El Nino. An El Nino is a warming of the equatorial Pacific Ocean that alters weather worldwide for about a year.
The oceans drove the globe to record levels. Not only were the world's oceans the warmest they've been in July, but they were 1.35 degrees warmer than the 20th-century average.
The heat hit hard in much of Europe and the Middle East. It was the hottest July on record in Austria, where records go back to 1767. Parts of France had temperatures that were on average 7 degrees above normal and temperatures broke 100 in the Netherlands, which is a rarity. And an Iranian city had a heat index (the "feels like" temperature) of 165 degrees, which was still not quite record.
Nine of the 10 hottest months on record have happened since 2005, according to NOAA. Twenty-two of the 25 hottest months on record have occurred after the year 2000. The other three were in 1998 and 1997.
This shows that despite what climate change doubters say, there is no pause in warming since 1998, Blunden said.
It doesn't matter if a month or a year is No. 1 or No. 2 or No. 5 hottest on record, said University of Georgia climate scientist Marshall Shepherd.
"The records are getting attention but I worry the public will grow weary of reports of new records each month," Shepherd said in an email. "I am more concerned about how the Earth is starting to respond to the changes and the implications for my children."

<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>.

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



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.

</div><figcaption class="wp-element-caption">Chaotic cancer protein finally controlled after decades of mystery</figcaption></figure>



<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.



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

<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.

<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.
