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

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.

Group Fails To Reach Agreement To Save Bluefin Tuna. An international body that monitors fisheries in most of the Pacific Ocean ended a meeting in Japan on Thursday without agreement on fresh measures to protect the dwindling bluefin tuna.
The Western and Central Pacific Fisheries Commission was unable to get a consensus on either short-term or long-term measures to help restore the bluefin population, whose numbers are estimated to have fallen 96 percent from unfished levels.
Last year, the 10-nation commission recommended that the catch of juvenile tuna be cut to half of its average level in 2002-2004. But conservation groups say more must be done to counter the sharp decline of the species.
The lack of a required three-quarters quorum prevented any agreement, since representatives from China, the Cook Islands, Vanuatu and the Philippines did not attend. So any decisions on new long-term measures were pushed back to 2016, the <a href="http://www.earth.com/news/nearly-all-native-japanese-bats-are-endangered/">Japanese</a> Fisheries Agency said.
Further inaction would likely prompt efforts by conservationists to get Pacific bluefin tuna banned from international trading, said a statement by The Pew Charitable Trusts, which is working to save the species.
"Unfortunately, the only outcome of this week's meeting is a guarantee that the Pacific bluefin tuna population will decline even further because of the continued inaction of ten governments responsible for the management of this species," Amanda Nickson, director of global tuna conservation for the group.
"The international community may be forced to look at a <a href="https://www.bing.com/search?q=global&amp;cvid=387298aa6d544428ae813fc60dfa7e57&amp;FORM=ANAB01&amp;PC=HCTS">global</a> trade ban to help save this species," she said in a statement.
The fisheries group also did not agree to a request by researchers to study the results of stricter fisheries management during their four-day meeting in the northern city of Sapporo.
Japanese eat 80 percent of the world's bluefin tuna, or "hon maguro," a sushi mainstay, and demand elsewhere in the world has kept growing. At a ritual new year auction, the top price for the fish jumped to about $7,000 a kilogram in 2013 but was a more reasonable $208 per kilogram this year.
Most of the fish caught are juveniles that have not had a chance to reproduce. The species could recover relatively quickly, however, since they are highly productive, spawning millions of eggs a year.
The environmental group Greenpeace praised <a href="http://www.earth.com/news/nearly-all-native-japanese-bats-are-endangered/">Japanese</a> representatives for proposing emergency measures to help the bluefin tuna, but said given the severity of its decline Japan should restrict sales of the fish. Group Fails To Reach Agreement To Save Bluefin Tuna
A stock assessment by the International Scientific Committee for Tuna and Tuna-like Species in the Northern Pacific Ocean found the levels of bluefin in 2012 at near their lowest ever of just 4 percent of original stocks.

Extra CO2 Can Help Plants But Only At Low Temperatures. Researchers say it's important to better understand the interplay between plant communities and the changing ratios of chemicals in the atmosphere and ocean.

Phytoplankton are plant-like microorganisms that serve as the foundation for many marine food chains. Like plants, phytoplankton covert sunlight into chemical energy and carbon dioxide into oxygen.

Logic suggests that extra CO2 would be advantageous to <a href="https://www.bing.com/search?q=phytoplankton&amp;cvid=054a1ef2ea6044099a93c43e641009e3&amp;FORM=ANAB01&amp;PC=HCTS">phytoplankton</a>. But a new study in the Arctic Ocean suggests growing levels of carbon dioxide offer a boost only at low temperatures.

According to researchers at the University of Western Australia, rising CO2 concentrations in Arctic waters are having a positive effect on phytoplankton growth -- but that effect fades as water temperatures rise. Extra CO2 Can Help Plants But Only At Low Temperatures

"This influx of CO2 could benefit primary producers, but we cannot forget that the temperature of the Arctic Ocean is also increasing almost three times faster than global temperatures," Lara Garcia-Corral, a researcher with UWA's Oceans Institute and School of Plant Biology, explained in a press release. "With the advent of the summer, when the temperature increases, the fertilizing effect of carbon dioxide diminishes to nothing and the ability of phytoplankton to capture CO2 decreases."

Even though CO2's plant-boosting effects may be limited to specific temperature ranges, researchers say it's important to better understand the interplay between plant communities and the changing ratios of chemicals in the atmosphere and ocean. Extra CO2 Can Help Plants But Only At Low Temperatures

"These changes have a significant impact on ecosystems and the regulation of CO2," Garcia-Corral said. "Therefore, they are fundamental to elaborate projections of future impacts of climate change."

Washington State Sues Feds Over Nuclear Waste . Washington state is suing the federal government again over cleanup of nuclear waste tanks at the Hanford Nuclear Reservation - this time over the danger posed to workers by vapor releases from underground waste-storage tanks.
In a federal lawsuit filed in Spokane on Wednesday, state Attorney General Bob Ferguson said the U.S. Department of Energy has known about vapors sickening workers at the site since at least the late 1980s, but hasn't fixed it - even though agencies have issued 19 reports on the problem. Hanford, on the Columbia River in eastern Washington, produced plutonium for<a href="http://www.earth.com/news/radioactive-carbon-from-nuclear-bomb-tests/"> nuclear</a> weapons from 1943 to 1987.
There were more than 50 reports of workers being exposed to vapors between January 2014 and April 2015, Ferguson said, and hundreds over the past few decades, with victims suffering from symptoms that include nosebleeds, brain damage and permanent loss of lung capacity. One longtime worker, Gary Sall, died from brain swelling linked to chemical vapors in 2011. Washington State Sues Feds Over Nuclear Waste Tanks
"Neither the Department of Energy nor its contractors have followed through to finally fix the problem and keep our workers safe," Ferguson told a news conference. "If you visited Hanford today, you'd find some workers at the tank farms still exposed to vapors seeping out of these tanks."
The lawsuit also names the Energy Department's contractor at Hanford, <a href="https://www.bing.com/search?q=Washington&amp;cvid=e3b63710753b4b7d9fbd974d38e5ed5a&amp;FORM=ANAB01&amp;PC=HCTS">Washington</a> River Protection Solutions, as a defendant. An advocacy group for Hanford workers, Hanford Challenge, and a union representing some of them, United Association of Steamfitters and Plumbers Local 598, filed a companion lawsuit.
In statements Wednesday, the department and its contractor said steps have already been taken to improve worker safety at the site, such as by increasing the use of self-contained breathing devices in areas of potential vapor exposure. Washington State Sues Feds Over Nuclear Waste Tanks
"The Department's top priority is the protection of our workforce, the public and the environment," Energy spokeswoman Carrie Meyer said in an email. Washington State Sues Feds Over Nuclear Waste Tanks
Washington River Protection Solutions said that since it took over as the contractor for tank operations in 2008, it has increased and improved sampling methods for detecting vapors and created wider vapor control zones for workers, and it's working on a multiyear plan to improve monitoring for vapors, among other things.
Washington sued the Energy Department in 2008 over the glacial pace of cleanup at Hanford, and the federal government agreed to a timeline for cleanup in a 2010 settlement. It's lagging in meeting those goals.
The Energy Department already asked for a one-year extension of its deadline for emptying nine leak-prone tanks, saying that having more employees wear respirators was slowing down the work.
Some 56 million gallons of toxic waste - much of it radioactive - is stored in 177 underground tanks on the 586-square-mile reservation. Most of the tanks are single-shelled and considered inadequate, and workers have been transferring the waste inside them to double-shelled tanks. The tanks are vented to keep dangerous gases from building up inside and causing explosions. While the vents do have filters that capture toxic particulates, the filters don't capture chemical vapors.
Current and former Hanford workers who attended Ferguson's news conference described a patchwork of safety practices that lead to some people carrying full breathing apparatus - like the air tanks firefighters carry into a burning building - while others nearby have no protection.
Pete Nicacio, business manager for Local 598, scoffed at Hanford's use of a rope delineating where workers need to wear breathing gear and where they don't, saying workers call it "the magic rope." He said his union members insist on breathing gear, and as a result, bosses have sometimes taken work away from them.
Tom Carpenter, executive director of Hanford Challenge, said a major problem is that Hanford doesn't have monitoring systems sophisticated enough to know what gases workers have been exposed to - some of which are dangerous enough to cause health problems at infinitesimally low concentrations. More than 1,500 chemical gases have been found in the tanks, and doctors are often forced to try to figure out which ones workers might have been exposed to based only on their symptoms.
Diana Gegg, 64, was working as a heavy equipment operator at Hanford one day in 2007 when she smelled something like chlorine or ammonia. She became dizzy and developed "flu-like symptoms which never went away and still haven't," as well as a bad stutter and memory problems.
After the news conference, she handed a reporter a typed statement because of her difficulty speaking.
Another worker, electrician Steve Lewis, said he has experienced inflamed skin and continual congestion in his throat. But, he added, "I've watched other people deal with things that were way worse than that."

Kivalina, Alaska Will Be A Global Warming Casualty Within A Decade. Residents of a Native village threatened by erosion were thankful for President Barack Obama's attention to their plight, saying they hope his visit to Alaska will help them secure funding to build a critical evacuation road to drier ground.
Even with a protective ocean rock wall, the impoverished Inupiat Eskimo community of Kivalina has no more than a decade left before erosion begins to force people from their homes, said Millie Hawley, president of Kivalina's tribal council.
Villagers say a couple homes near the village lagoon are already threatened by <a href="http://www.earth.com/news/oahu-could-lose-40-percent-of-its-beaches-to-coastal-erosion/">erosion</a>, which has come within 3 feet of the foundation of one dwelling. Kivalina, Alaska Will Be A Global Warming Casualty Within A Decade
With about 400 people, Kivalina is located at the tip of a barrier reef 80 miles northwest of the regional hub of Kotzebue, where Obama was scheduled to visit Wednesday during his tour of Alaska to show the effects of climate change.
In July, a White House advance team visited Kivalina about 625 miles northwest of Anchorage to scope it out as a possible stop for the president, but the visit didn't materialize.
The president, however, did get a look at Kivalina on Wednesday as Air Force One did a flyover when it was en route to Kotzebue. The president's plane came down low to the ground, and the village was visible on the left side of the plane.
The pilots turned the plane around to fly over Kivalina again so the president could get a second look.
"On my way here, I flew over the island of Kivalina, which is already receding into the ocean," Obama said during his address in Kotzebue.
He described how waves sweep across the entire barrier island at times.
"For many of those Alaskans, it's no longer a question of if they are going to relocate, but when," Obama said. "Think about that. If another country tried to do wipe out an entire town, we'd do everything in our power to protect it."
Hawley was among 10 village leaders who flew by charter plane to Kotzebue, and she introduced the president before his address.
"I think we're in a prominent place to get our issues addressed on climate change," Hawley said. "It's all about life safety and food security."
Brian Deese, Obama's senior adviser for climate and energy issues, said the federal government was working to address concerns in Kivalina and similar villages that find it hard to access federal funds for relocation.
He said that Alaska Natives had identified USDA water infrastructure grants as a particular source of funding that could be helpful.
Hawley said the village wants to build a 7-mile evacuation road and causeway to the mainland where residents voted several years ago to build a future school at a potential relocation site.
Erosion is only part of the impact of climate change, which is accelerating in the Arctic. Villagers say the migrations of animals they rely on for much of their diet, such as bearded seal and caribou, have become unpredictable and is taking place far earlier. That is forcing residents to travel farther to hunt.
For the past few years, the caribou that used to show up by the thousands near the village have all but disappeared.
Also, the ice that protects the shores from storm surges is forming later and melting earlier, allowing stronger storms to lash out at the eroding coastline.
Joseph Swan Jr., who manages Kivalina's water plant, has lived in the village all his 47 years. He welcomed the opportunity for the village to be on Obama's radar because the president has global influence.
"It's great that somebody's finally paying attention, real attention, and letting us know we're not invisible," Swan said.

Global Climate Pact Starting To Take Shape. U.N. climate talks are plodding ahead toward a worldwide deal to fight global warming, with negotiators agreeing to start work on a draft agreement for a global climate pact.
A weeklong session in Bonn finished Friday with the two officials leading the talks getting the green light to turn a sprawling negotiating text into a coherent draft by the next round of talks in October. The deal is expected to be signed in <a href="https://www.bing.com/search?q=paris&amp;cvid=921d165e7ba74c23a98f3a5357617f19&amp;FORM=ANAB01&amp;PC=HCTS">Paris</a> in December.
Crunch issues that remain include resolving how to share the burden of slashing climate-warming carbon emissions and helping poor countries adapt to rising sea levels and other effects of global warming.
The U.S., European Union and other developed nations want the new deal to reflect evolving national circumstances so <a href="http://www.earth.com/news/less-vegetation-is-appearing-in-countries-that-need-it-most/">countries</a> take on more responsibilities as their economies and their carbon emissions grow. But India and others want to retain the firewall between developed and developing countries that's been at the core of previous agreements, requiring only developed nations to set binding targets to cut emissions.
"Some countries have a GDP per capita of more than $20,000, others have just $400," India's chief negotiator Ravi Prasad told The Associated Press. "There is a clear differentiation in the real world ... so how can we not have a difference in how we deal with climate change?"
China and India say the industrialized countries have a historical responsibility for climate change because they've released the most emissions over time, mainly from burning oil, coal and gas. However, developed country negotiators said the two sides are moving closer on the issue.
"We are not that far away," EU delegate Sarah Blau said.
In practice, the rich-poor division is already blurred. Except for the very poorest, all countries are supposed to submit pledges to cut emissions for the new deal. China submitted its pledge in June; India is expected to do so this month.
Also, several developing countries including South Korea, Mexico and Colombia have joined rich nations in pledging contributions to a climate fund to help the poorest countries deal with climate change.
Delegates in Bonn appeared to move closer on another controversial issue: how to help vulnerable nations deal with climate impacts they cannot adapt to, such as rising seas that threaten their coastlines and drinking water. Global Climate Pact Starting To Take Shape
The U.S. and other Western countries are concerned the issue could lead to claims of liability and compensation for climate change losses. The U.S. presented a proposal in Bonn to continue discussions on the issue, even if it's not enshrined in the Paris deal.
"I'm sure throughout the negotiations we'll be able to find suitable language that caters to the interests of both us and the U.S.," said Amjad Abdulla of the Maldives, the chief negotiator for small island states.
Some delegates and environmental groups were disappointed with the slow pace in Bonn but U.N. climate chief Christiana Figueres urged patience.

Global Climate Pact Starting To Take Shape

Global Climate Pact Starting To Take Shape. U.N. climate talks...

Work On 10 Sites Suspended After Colorado Spill. Site investigations and some cleanup work at 10 polluted mining complexes in four states were suspended because of conditions similar to those that led to a massive wastewater blowout from an inactive Colorado gold mine, U.S. Environmental Protection Agency officials said.
The sites include three in California, four in Colorado, two in Montana and one in Missouri, according to details obtained by The Associated Press following repeated requests for the information. Work On 10 Sites Suspended After Colorado Spill
They have the potential for contaminated water to build up inside mine workings, EPA Assistant Administrator Mathy Stanislaus said. That would set the stage for a possible spill such as last month's near Silverton, Colorado, where an EPA team triggered a 3 million gallon blowout of toxic sludge while doing excavation work on the inactive Gold King Mine.
The accident fouled rivers in three states and attracted harsh criticism of the EPA for not being prepared despite prior warnings that such a spill could happen.
"We want to take extra caution before we initiate any work," Stanislaus said of the work suspensions. Some the mines were abandoned decades ago and have grown more unstable over time, raising the risk of an accident.
The stop-work order was issued last month but officials for weeks refused to disclose specifics.
Cleanup efforts on some of the mines have been going on for years yet remain unfinished, underscoring the complexity of a long-running attempt to address an estimated 500,000 abandoned mines across the U.S. Work on others was in the early stages.
In a report to Congress delivered Friday, the Government Accountability Office said federal agencies identified thousands of contaminated mine sites in recent years - even as their attempts to assess what harm is being done to people and the environment have lagged.
Further investigations were needed to gauge the danger posed by the 10 mining complexes under the suspension before work could safely resume, according to internal EPA documents released by the agency.
That includes categorizing their level of hazard. For those deemed a "probable hazard," the EPA plans to keep the work stoppage in place until emergency plans are drawn up to deal with any accident.
The agency also wants to get the results of an Interior Department investigation into the Colorado accident before proceeding on most of the other sites. That's expected in late October, department officials said.
Prior to the Aug. 5 Gold King spill, the EPA and its contractor, Environmental Restoration LLC of St. Louis, appeared to have only a cursory emergency response plan in the event of a spill, according to documents released under public records requests.
There was no cellphone coverage at the remote site in the San Juan Mountains, and the workers did not have a satellite phone, according to EPA documents. As a result, they had no way to immediately communicate with the outside world when the rust-colored water loaded with heavy metals, including lead and arsenic, began rushing toward downstream communities.
One of the sites where cleanup work was subsequently halted was the Standard Mine in the mountains above Crested Butte, a ski town in west-central Colorado. Crested Butte Mayor Aaron Huckstep said that after work was suspended, the EPA met with residents and officials and made sure cleanup workers could communicate directly with the town in an emergency.
"They understood that they needed to make sure that the communication channels and the communication protocols were in place and the folks knew who to call and when to call them," Huckstep said.
EPA documents show wastewater at the site periodically spills over a crudely-built impoundment, raising concerns about a "potential catastrophic failure" and the possibility of tainting Crested Butte's drinking water. But Huckstep said he didn't believe the Standard Mine was a threat to blow out, based on EPA statements and differences in the land.
The EPA said the town's water meets safety standards.
Colorado Department of Public Health and Environment spokesman Warren Smith said wastewater flowing from the mine was not considered an acute health threat. Work on the site resumed Sept. 4 after officials determined appropriate safety measures were in place.
The Aug. 12 stop-work order from EPA Administrator Gina McCarthy did not apply to sites where halting operations would pose a threat to people or increase the potential for harm to the environment, according to internal EPA documents.
Also exempted were portions of the 10 stopped projects where construction already was completed, such as treatment systems for contaminated water that pours continually from many abandoned mine shafts.
That's the case for two sites listed in northern <a href="https://www.bing.com/search?q=california&amp;cvid=fd080693bd5c40978847ead77d982ee9&amp;FORM=ANAB01&amp;PC=HCTS">California</a> - the Leviathan sulfur mine near the town of Markleeville and the Iron Mountain metals mine near Redding. Water continues to be collected at the sites, to be treated and then discharged.
"We have not received any direction from EPA to shut down our treatment. It's been business as usual for us out there," said Scott Ferguson with the Lahonton Regional Water Quality Control Board, which is involved with the Leviathan mine.
EPA spokeswoman Laura Allen said other work at the two mines has stopped, including plans to remove a beaver dam at Leviathan.
The following mining sites are affected by a U.S. <a href="https://www.earth.com/news/sea-stars-may-be-drowning-in-their-environment/">Environmental</a> Protection Agency decision to suspend investigations and some cleanup work at locations with similarities to a mine involved in a 3-million-gallon wastewater spill near Silverton, Colorado, in August:
-Leviathan Mine, near Markleeville, California. An open-pit sulfur mine that closed in 1962. Acid mine water drains from the 250-acre site and has killed off aquatic life in nearby creeks.
-Iron Mountain Mine, northwest of Redding, California. After operating for a century, the mine closed in 1963. Periodic uncontrolled spills have caused major fish kills in surrounding waterways.
-Standard Mine, near Crested Butte, Colorado. The former zinc, lead, silver and gold mine in the Gunnison National Forest shut down in 1966. Heavy metals including cadmium, zinc, lead and copper have contaminated Elk Creek, which drains into another stream that provides drinking water for Crested Butte.
-Southwest Jefferson County mining complex, near De Soto, Missouri. As many as 190 mines once operated in this 166-square-mile area first developed in the early 1800s. Lead has contaminated the soil and groundwater of residential properties in the area.
-Argonaut Mine, Jackson, California. A former gold mine that closed in 1942, Argonaut was the site of a 1922 fire that killed 47 workers. The 65-acre site contains highly contaminated soils and mine tailings.
-Flat Creek/Iron Mountain Mine, near Superior, Montana. It produced silver, lead, gold and other ores and closed in 1953. Mine tailings were used as fill and roadway material in Superior. Flooding has spread piles of contaminated waste throughout the Flat Creek flood plain.
-Upper Tenmile Creek mining area, southwest of Helena, Montana. Mining in the area, which is upstream of drinking-water sources for Helena, largely ceased in the 1930s. Surface waters and river sediments contain high levels of leads, arsenic, cadmium, copper and zinc that drained from the mines.
-Camp Bird Mine, near Ouray, Colorado. A former gold and silver mine that also produced other metals and operated from 1900 to 1990. Colorado health officials said they were not aware of any cleanup work being done.
-James Creek, 40 miles northwest of Denver. Colorado health officials said they were not aware of any cleanup work being done. No further information was available.
-Eagle River, central Colorado. No further information was available.

Work On 10 Sites Suspended After Spill

Work On 10 Sites Suspended After Colorado Spill. Site investigations...

Global Climate Pact Starting To Take Shape. U.N. climate talks are plodding ahead toward a worldwide deal to fight global warming, with negotiators agreeing to start work on a draft agreement for a global climate pact.
A weeklong session in Bonn finished Friday with the two officials leading the talks getting the green light to turn a sprawling negotiating text into a coherent draft by the next round of talks in October. The deal is expected to be signed in<a href="https://www.bing.com/search?q=paris&amp;cvid=921d165e7ba74c23a98f3a5357617f19&amp;FORM=ANAB01&amp;PC=HCTS"> Paris</a> in December.
Crunch issues that remain include resolving how to share the burden of slashing <a href="http://www.earth.com/news/mangrove-forests-in-oman-were-wiped-out-by-climate-change/">climate</a>-warming carbon emissions and helping poor countries adapt to rising sea levels and other effects of global warming. Global Climate Pact Starting To Take Shape
The U.S., European Union and other developed nations want the new deal to reflect evolving national circumstances so countries take on more responsibilities as their economies and their carbon emissions grow. But India and others want to retain the firewall between developed and developing countries that's been at the core of previous agreements, requiring only developed nations to set binding targets to cut emissions.
"Some countries have a GDP per capita of more than $20,000, others have just $400," India's chief negotiator Ravi Prasad told The Associated Press. "There is a clear differentiation in the real world ... so how can we not have a difference in how we deal with climate change?"
China and India say the industrialized countries have a historical responsibility for climate change because they've released the most emissions over time, mainly from burning oil, coal and gas. However, developed country negotiators said the two sides are moving closer on the issue.
"We are not that far away," EU delegate Sarah Blau said.
In practice, the rich-poor division is already blurred. Except for the very poorest, all countries are supposed to submit pledges to cut emissions for the new deal. China submitted its pledge in June; India is expected to do so this month.
Also, several developing countries including South Korea, Mexico and Colombia have joined rich nations in pledging contributions to a climate fund to help the poorest countries deal with climate change.
Delegates in Bonn appeared to move closer on another controversial issue: how to help vulnerable nations deal with climate impacts they cannot adapt to, such as rising seas that threaten their coastlines and drinking water.
The U.S. and other Western countries are concerned the issue could lead to claims of liability and compensation for climate change losses. The U.S. presented a proposal in Bonn to continue discussions on the issue, even if it's not enshrined in the Paris deal.
"I'm sure throughout the negotiations we'll be able to find suitable language that caters to the interests of both us and the U.S.," said Amjad Abdulla of the Maldives, the chief negotiator for small island states.
Some delegates and environmental groups were disappointed with the slow pace in Bonn but U.N. climate chief Christiana Figueres urged patience.
"The proof is in the pudding," she said. "And the pudding is going to come out of the oven in Paris."

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



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



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.

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.

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



The full study was published in the journal Current Biology.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

</div></figure>



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."

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.

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



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



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



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



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



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



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

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



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



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

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



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



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