Plastic may not always float where we expect it. The ocean’s surface might look clean in some places, but far beneath the waves, a different story is unfolding. 



In the southeastern Mediterranean, the deep seafloor is turning into a massive storage ground for plastic packaging, especially bags. A new study shows how this <a href="https://www.earth.com/news/large-retailers-are-replacing-plastic-bags-with-eco-friendly-paper-bags/">waste</a> ends up thousands of feet below the surface, and the answer isn’t as simple as trash just “sinking.”



<h2 class="wp-block-heading" id="h-plastic-in-the-deep-sea">Plastic in the deep sea</h2>



Plastic debris has entered every corner of the ocean, but previously, most of the research has concentrated on floating plastic or beach trash. That changed with this latest study, which took a closer look at what is occurring on the ocean floor. 



Scientists discovered that the Levant Basin - a deep section of the eastern <a href="https://www.earth.com/image/two-continents-meet-along-the-mediterranean-coastline/">Mediterranean</a> off the coasts of Israel, Egypt, and Turkey - is among the world's most contaminated deep-sea areas.



“We used trawls to survey the seafloor and we mainly found plastic bags and packaging that dominate the debris,” said Xing-Yu Li from the <a href="https://www.haifa.ac.il/?lang=en">University of Haifa</a>, the study’s lead author.



This raised a question: how does something so light - something meant to float - end up nearly a mile underwater?



<h2 class="wp-block-heading" id="h-a-forensic-approach-to-trash">A forensic approach to trash</h2>



To answer that, the team decided to treat each plastic item like a crime scene. Every piece of debris was carefully examined using a method called multi-marker analysis. 



This approach looks at everything about the plastic - size, shape, color, material, surface features, and even what kinds of things are stuck to it, like tar or <a href="https://www.earth.com/news/marine-organisms-may-adapt-to-climate-change-but-with-hidden-costs/">marine organisms</a>.



“In the multi-marker approach anything that is found on a piece of plastic is an evidence,” said Xing-yu. “We extracted as many evidence as possible from every piece of waste, more than many previous studies, to build a fuller, more detailed view of the bottom waste.”



Instead of just counting how much trash was found, this method helped researchers understand how it got there, why it sank, and where it might have come from.



<h2 class="wp-block-heading" id="h-why-some-plastic-doesn-t-sink">Why some plastic doesn’t sink</h2>



Most of the plastics found were <a href="https://www.earth.com/news/everyday-kitchen-tool-that-could-be-leaching-toxins-into-your-food-polypropylene-cutting-board/">polyethylene</a> - the same material used in grocery bags. Normally, this kind of plastic floats. But when additives like calcium carbonate (CaCO₃) are mixed in during manufacturing, the plastic becomes heavier. 



Those with CaCO₃ sank closer to the shore. Others, without these additives, drifted farther out before eventually settling on the seafloor.



The study also revealed that the deep basin at over 3,000 feet deep acts like a trap. Pressure and fine sediments help keep the plastic down. 



<a href="https://www.earth.com/news/biofilms-could-change-the-way-we-track-plastic-pollution/">Biofilms</a>, which are slimy layers formed by microbes, usually help weigh plastics down too, but they don’t grow well in this part of the sea. Instead, things like tar, sand, and tiny shells helped plastics stay put.



The scientists noted that these plastic films - while thin and lightweight - are ending up where they can do the most long-term damage. 



Even more troubling, the team found that some of this plastic could become buoyant again if disturbed, but because of how the deep sea works, that rarely happens. Once the plastic settles, it stays.



<h2 class="wp-block-heading" id="h-where-the-trash-is-coming-from">Where the trash is coming from</h2>



The plastic pollution isn’t only from local beaches. According to the research, land-based sources from Egypt, Israel, and Turkey are a big part of the problem. 



Shipping also plays a role, especially in deeper waters. Surprisingly, fishing was not a major contributor - possibly due to strict Israeli regulations.



For years, scientists noticed high levels of plastic at the seafloor, but they didn’t fully understand why. 



“For years in our monitoring reports we have reported a high concentration of plastic debris in this area. It was an unsolved mystery as we know that <a href="https://www.earth.com/news/ocean-floor-harbors-up-to-11-million-tons-of-plastic-debris/">plastic debris</a> should remain floating on the sea surface. Now we have a deep understanding of how it happens,” said Dr. Yael Segal from Israel Oceanographic and Limnological Research (IOLR). 



“The Eastern Mediterranean is the most polluted area in the world, and we must take action for the sake of the next generation.”



<h2 class="wp-block-heading" id="h-long-term-risks-to-marine-life">Long-term risks to marine life</h2>



<a href="https://www.earth.com/news/grapevines-could-offer-a-breakthrough-alternative-to-plastic-packaging/">Plastic packaging</a> is cheap, easy to produce, and used globally - but it doesn’t go away. It breaks into smaller pieces and can remain in the environment for hundreds of years. 



Deep-sea habitats are already fragile, and adding plastic into the mix could disrupt food webs, introduce toxins, and harm species that haven’t even been fully studied yet.



“As the head of the national monitoring program, I see firsthand how plastic pollution is impacting the entire sea environment: beaches, water, sea bottom, and even local turtle populations,” said Dr. Segal.



Professor Revital Bookman said that the discovery is fascinating in the worst possible way. 



"The eastern Mediterranean is quietly turning into a deep-sea landfill. Plastics that we use for only a few minutes are ending up trapped for centuries, threatening deep marine ecosystems we barely understand," noted Professor Bookman. 



<h2 class="wp-block-heading" id="h-what-needs-to-happen-next">What needs to happen next</h2>



According to the researchers, this study changes how we should think about ocean pollution. Plastic doesn’t just float around until it hits a beach. It travels far, interacts with other pollutants like tar, and ends up in hidden places. 



“This previously overlooked dynamic necessitates a broader perspective on pollution processes in marine environments,” said Professor Bookman. 



“Without systematic deep-sea accounting, we risk underestimating the true environmental footprint of plastic pollution and misallocating mitigation efforts by neglecting offshore and deep-sea sinks.”



To deal with this, the experts call for coordinated efforts across the region. Countries that share the sea need to work together on monitoring, cleanup, and prevention. 



Without a shared strategy, plastics will continue piling up, silently choking one of the planet’s most mysterious ecosystems.



The full study was published in the journal <a href="https://www.sciencedirect.com/science/article/abs/pii/S0025326X25009671?via%3Dihub" target="_blank" rel="noreferrer noopener">Marine Pollution Bulletin</a>.

Hidden plastic graveyard uncovered in the deep Mediterranean Sea

Plastic may not always float where we expect it. The ocean’s surface might look clean in some places, but far beneath the waves, a different story is unfolding. In the southeastern Mediterranean, the deep seafloor is turning into a massive storage ground for plastic packaging, especially bags.

In Scotland, a mysterious illness has led to a depressing sight along the coast: scores of dead or dying seals.

The country’s harbor seals have been dying in droves, with some areas losing up to 90 percent of the marine mammals since 2000. Harbor seal populations in northern Scotland and Orkney have dropped by at least 7,000 in just ten years. In a bid to find out the cause of these deaths, marine biologists fitted the animals with their smartphones – well, tags using smartphone technology. The tags allowed the biologists to follow different groups seals through their daily lives, in hopes of finding the deadly common denominator among them. 

Though the seals can’t call in any dangers they face, the biologists can track the water they’re spending time in to see if they’re running with any harmful elements.

The good news? While there’s still a lot of data to examine, the biologists have a prime suspect already: red algae blooms. 

The scientists used the GPS data collected by the seals’ tags to map their favorite feeding sites. Water samples taken at the sites show traces of the domoic acid left behind by red algae.

The bad news? Domoic acid is a dangerous neurotoxin. It accumulates in fish that live in areas with red algae blooms and the “red tides” they produce, and when the seals eat the fish, they’re slowly poisoned. 

Red tides off of the California coast have led to domoic acid toxicity in sea lions, and scientists there believe that the neurotoxin may be causing memory loss. 

However, knowing a potential cause behind the harbor seals’ dwindling numbers can help biologists create new solutions for the problem. For example, scientists are testing treatments for sea lions affected by domoic acid toxicity at the <a href="http://www.marinemammalcenter.org/about-us/News-Room/2015-news-archives/toxic-algal-bloom.html">Marine Mammal Center</a> in Sausalito, California. 

The Scottish scientists aren’t settled on domoic acid yet. It seems the most likely culprit from early data returned by the tags, but the scientists hope to follow the seal populations for a couple of years to get a better idea of what they’re doing.

The smartphone-style tags were designed by the <a href="https://www.st-andrews.ac.uk/">University of St. Andrews</a>, which partnered with cellphone provider <a href="https://www.vodafone.com/">Vodafone</a> to track the initial 10 seals in the study. The tags transmitted GPS data over Vodafone’s network back to the university’s Sea Mammal Research Unit. 

The research team at the University of St. Andrews provides updates about the Vodafone study and other seal research at their <a href="http://synergy.st-andrews.ac.uk/harbourseals/">Harbour Seal Decline Project</a> blog.

Every year, thousands of people die in earthquakes around the world. However, new research shows that small gravity shifts could offer valuable minutes for people to flee to safety in areas that are about to shake, rattle and roll.

When an earthquake is triggered, a few changes take place before the shaking is actually felt. Among them are tiny shifts in the Earth’s gravitational field, said Professor Jean-Paul Montagner, a seismologist with the <a href="http://www.ipgp.fr/en">Institut de Physique du Globe de Paris</a>. 

In fact, the gravity shifts may come minutes before seismic waves can be detected by instrumentation – the current earthquake warning system. By the time seismic waves are felt, the earthquake has already begun, but gravitational shifts can be detected at the speed of light, the <a href="http://www.nature.com/articles/ncomms13349">new research found</a>. 

Montagner believes that a network of instrumentation that can pick up gravitational shifts might offer a better early warning system.

The extra seconds or even minutes could save thousands of lives, Montagner and his research team said.

The team first began to look at how earthquakes affect gravity in the wake of the massive Tohoku earthquake that struck Japan on March 11, 2011. The six-minute, 9.0-magnitude quake triggered a tsunami and a major nuclear disaster. 

The official death toll for that disaster stands at 15,894, with more than 2,500 still missing. Thousands more were injured, and hundreds of thousands were left homeless.

Previous research showed that the Tohoku quake left scars on the Earth’s gravitational field that still persist. Montagner’s team wondered whether there may have been signs in the Earth’s gravity before the tremors began that a quake was coming.

The researchers found tiny gravitational signals just before the quake began. The signals could be detected far from the quake’s epicenter. 

While the scientists can’t yet pinpoint where an earthquake is going to happen, further research and a more extensive sensor network could provide a warning when a massive earthquake or series of several earthquakes are about to occur, the researchers said.

Their findings were published in the journal <a href="http://www.nature.com/ncomms/">Nature Communications</a>.

Australasian marsupials survived ancient climate change, but may not survive the next.

As climate change progresses, australasian marsupials face a high risk of extinction. But according to a recent study, they may actually have survived ancient climate change millions of years ago. 

The study, published in <a href="http://www.nature.com/srep/">Scientific Reports</a>, was conducted by an international team of researchers led by Dr. Benjamin Kear from the Museum of Evolution at <a href="https://www.uu.se/en/">Uppsala University</a>.  "We used bandicoots as a model to examine the radiation of marsupials relative to climate change through time,” said Dr. Kear. “Bandicoots are the marsupial equivalents of rodents and rabbits that today occupy a spectrum of desert through to rainforest habitats across Australia, New Guinea and surrounding islands. Alarmingly, however, most bandicoot species are under dire threat of extinction from introduced predators, habitat loss, and human hunting,"

The bandicoot fossils indicate that roughly 5-10 million years ago, a climate shift to much drier conditions drove many species into extinction and prompted others to adapt into their modern evolutionary form. Dr. Ken Aplin of the <a href="https://naturalhistory.si.edu/">Smithsonian National Museum of Natural History</a> noted, "The evolution of Australia's mammals has long been linked to aridity. Yet this hypothesis is based upon only a few distinguishing features found in the teeth and skulls of modern species.” 

Modern bandicoots are estimated to have appeared less than 5 million years ago, with their most ancient relative species existing in ancient rainforests up to to 20 million years ago. But Dr. Aplin uncovered fossils from the Aru Islands of Eastern Indonesia that indicate a new fossil bandicoot, Lemdubuoryctes aruensis, included isolated teeth from over 50 million years ago.

But Lemdubuoryctes aruensis did not inhabit rainforests. Instead, they lived in a large savannah plain between New Guinea and Australia during the last glacial maximum. 

According to Professor Michael Westerman from La Trobe University in Australia, "While retreating rainforests and spreading grasslands did provide a backdrop for ecosystem change 5-10 million years ago. The Australian fauna likely adapted via changing its distribution rather than undergoing wholesale extinction and replacement. This agrees with our results from DNA, which indicate that modern desert-living bandicoot groups pre-date the onset of aridity by as much as 40 million years.”

Added Dr. Kear, “"Bandicoots, like other Australasian marsupials, probably occupied a range of different habitats over many millions of years. However, our study has further implications for future conservation. Arid zone bandicoots are amongst the most vulnerable mammals in Australasia today, with multiple species having gone extinct within the last 100 years. By demonstrating their profound evolutionary antiquity we can thus serve to highlight how extremely urgent it is to protect these living fossils as part of Australia's unique biodiversity.”

Scientists prepare aquatic biodiversity map for western United States

When it comes to the preservation of aquatic endangered species, scientists have historically struggled to come up with a cohesive index reflecting the full spectrum of biodiversity in ecosystems.  But researchers based in Boise, Idaho have been busy preparing a massive aquatic biodiversity map containing information on thousands of species inhabiting rivers and streams of western United States. The team, led by biologist Dan Isaak of the <a href="http://www.fs.fed.us/">U.S. Forest Service</a>, hope to have the first Aquatic Environmental DNA Atlas ready for the public by next summer. 

According to Isaak, “it’s kind of the Holy Grail for biologists to know what a true biodiversity map looks like. To have that formatted digitally so you can do lots of science with it will be transformative in terms of quality of information we’ll have to conserve species.”

Such an aquatic biodiversity map could be incredibly useful in land management decision making as well as how to allocate financial resources. Isaak suggests taking these surveys on an annual basis to allow experts to chart how ecosystems change over time. Quickly evolving technology now allows scientists to identify organisms by DNA using a small water sample. Soon, they will be able to identify multiple species using a single test.

“It’s just been an ongoing revelation,” says Isaak. “It still seems like magic to me that you can go take a water sample and you have instruments powerful enough to discern what species are present.”

Michael Schwartz, director of the Forest Service <a href="http://www.fs.fed.us/research/genomics-center/">National Genomics Center for Wildlife and Fish Conservation</a> in Missoula, Montana, notes that the findings of such a study could raise entirely new questions, such as as the presence of potentially threatening species. “Any time science undertakes large projects like this, they payouts can be in directions you don’t expect.” 

The Aquatic Environmental DNA Atlas for the western U.S. began with a project known as the Bull Trout Environmental DNA Atlas which covered just Montana, Idaho, Oregon, Nevada, and Washington. That study revealed bull trout to inhabit areas it was previously thought not to exist. A more comprehensive, census-style understanding of aquatic species populations will be crucial to the success of environmental preservation projects, particularly as climate change continues to alter the landscape.

Isaak is also involved with a project known as <a href="http://www.fs.fed.us/rm/boise/AWAE/projects/ClimateShield.html">The Cold Water Climate Shield</a> which aims to identify water bodies that could serves as refuge for cold water species like the bull trout as the climate continues to warm. The Cold Water Climate Shield and Aquatic Environmental DNA Atlas can work in tandem to identify which species exist in which areas and which may need new homes in the near future.

Scientists have been observing and recording the thinning of the Pine Island Glacier in West Antarctica since 1992, but the glacier appears to have begun its retreat decades ago.

New research by an international team of scientists found that the glacier was beginning to decline by 1945 at the latest. 

The Pine Island Glacier ice shelf currently floats in seawater. However, sediment cores taken from the ocean’s floor below show that until 1970, the glacier was “grounded,” or settled on the seabed. The grounded portion of the glacier first began to retreat by 1945.

Even when weather events such as El Niño that warm the water were absent, the glacier continued its retreat.

The Pine Island Glacier is part of the Western Antarctic Ice Sheet, which has been thinning and breaking apart for approximately four decades. Pine Island is just one of a number of glaciers that have been melting.

The fact that the Western Antarctic Ice Sheet as a whole is melting and not just one or two glaciers indicates that an outside force – perhaps global climate change – is influencing the phenomenon, the research team said.

The team used sediment cores collected with Autosub, an autonomous underwater vehicle, and satellite imagery dating back several decades to determine how long Pine Island Glacier has been thinning and how extensive its retreat has been.

Among their findings were satellite images from 1973, the earliest year available, that showed a hump of ice where an underwater ridge is located. In images taken a few years later, the ice hump was gone.

The scientists also found plutonium deposits in the sediment cores – left behind by above-ground nuclear weapons testing in the early 1950s. The appearance of plutonium fallout deposits in the seabed indicate that the ice sheet had begun its retreat before those tests.

The study’s findings indicate that the glaciers in western Antarctica have been thinning for several decades, and their retreat may be irreversible, the scientists said.

Some innovators are finding animal inspiration – not from nature, but from one of the world’s most popular pets. It turns out that studying cat tongues has offered up an array of ideas that could be useful in robotics, medicine, and the beauty industry.

Researchers based at <a href="http://www.gatech.edu/">Georgia Tech</a> used macro and high-speed videography to record cats as they groomed, then used the imaging to print three-dimensional models at a 400 percent scale. 

The project revealed that the sandpaper-like feel of a cat’s tongue is due to hook-like features that are the shape and sharpness of tiny claws. These little hooks make cat tongues ideal for detangling their fur. The flexibility of the tongue and the spines themselves help with this task.

And that gave the researchers some ideas. The most obvious, of course, is that hairbrushes modeled after cat tongues instead of with stiff, straight bristles might make detangling hair easier – and be easier to clean. 

The hooked shape of the spines on cats’ tongues make them “self-cleaning,” with caught fur sliding off easily. A similarly shaped brush could be cleaned by simply sliding a hand from the tip to the end.

However, the research could also offer up improved grips for soft robotics systems, as well as innovations in wound cleaning.

In robotics, engineers have struggled to create soft materials that can grip surfaces. The cat’s soft, flexible tongue could offer a model for a solution. 

The scientists aren’t done studying cats. They’ve examined the tongues of domestic cats, but would like to also study large cats like lions and tigers so they can compare the structures of their tongues. They’re hoping to find out how the spacing of the spines affects resistance. 

The researchers presented their findings at the 69th annual meeting of the <a href="https://www.aps.org/units/dfd/">American Physical Society’s Division of Fluid Dynamics</a>. They’re planning to create mimic technology based on their findings.

When it comes to solar energy, most research and development funding goes into the standard silicon solar cells – and that needs to change, some researchers say.

Yet if solar cells could be made thin and flexible enough to print, they could be mass-produced quickly and easily, said Dr. Yi-Bing Cheng of <a href="http://www.monash.edu/">Monash University</a>. He believes more research should be focused on creating thin solar cells that can be produced cheaply and safely.

The silicon-based solar panels that make up about 90 percent of modern production are rigid and bulky. The amount of energy it takes to produce each one is equal to about 10 percent of its lifetime energy production, according to scientists.

Photovoltaic cells are already being produced on thin, flexible films, Cheng pointed out. Some are even more better at converting light to energy than the familiar silicon-based solar panels. 

Some of these, like thin photovoltaic devices made using perovskite crystals, are as efficient as conventional solar panels in converting light into energy. However, perovskite crystals degrade under heat and humidity, and without additional research, they won’t be useful. 

This is the case with many solar panel alternatives, Cheng said. They aren’t sustainable either due to the manufacturing process – which often use heavy metals or hazardous solvents – or because they simply don’t last as long as conventional solar panels. Most cannot be affordably printed using modern printing technology because of the level of precision needed.

Cheng believes new research into these possibilities can solve most of those problems, but funding is needed, he said.

With research into printable solar cells, they could be integrated into watches, cellphones, windows, walls, and other surfaces, turning them all into solar energy production devices, Cheng said. 

Public funding could help scientists learn how to remove or mitigate the problems with paper-thin photovoltaic devices, and study how to produce them quickly and cheaply, Cheng said. It could also encourage private investors to take a risk on alternatives to bulky solar panels, he added. 

Cheng made his case for more funding for research into printable solar cells in the journal <a href="http://www.nature.com/news/print-flexible-solar-cells-1.21019">Nature</a>.

To most people, dirt is dirt. To those who study soil science, though, every type has different physical properties and individual characteristics.

Two of those soil scientists – Dr. Robson Armindo of the <a href="http://www.ufpr.br/portalufpr/">Federal University of Paraná</a> in Brazil and Dr. Ole Wendroth of the <a href="http://www.uky.edu/UKHome/">University of Kentucky</a> – thought the standard soil physical quality index just didn’t offer enough information to those who depend on the land, such as farmers.

They decided to take a closer look at interactions between soil, air and water to see if they could do a better job. 

In <a href="https://dl.sciencesocieties.org/publications/sssaj/abstracts/80/5/1167">a new study</a>, the pair looked at crop needs, land use and climate to develop a new set of evaluations that could replace the quick and dirty methods already in place to determine soil quality. They considered questions such as how water flows over a soil’s surface or is absorbed, and how hard it would be for roots or farming equipment to go through a soil type.

Armindo and Wendroth tested their resulting five indices and two functions to test soil in Germany, the U.S. and Brazil, and found that they could give an accurate picture of a particular soil’s quality.

The new evaluation methods can help determine if property is good for farming or would make a good foundation for a building. For farmers, it goes farther, helping them to determine which crops would do well on a piece of land.

The equations will help land managers and farmers determine how land can best be used, and can help to save the time and money that often goes into trial and error, Armindo and Wendroth said. 

Research funding came from the U.S. National Institute of Food and Agriculture, the State of Kentucky and the Brazilian Coordination for the Improvement of Higher Education Personnel. Armindo and Wendroth’s findings were published in <a href="https://dl.sciencesocieties.org/publications/sssaj">Soil Science Society of America Journal</a>.

What happens when movie magic meets modern paleontology? “Jurassic World: The Exhibition,” which opened Friday at the <a href="https://www.fi.edu/">Franklin Institute</a> in Philadelphia.

The touring exhibit is “the closest you will ever come to living dinosaurs,” according to the Institute. 

Instead of the standard dino skeletons, “Jurassic World” used research from working paleontologists to create awe-inspiring, life-sized animatronic dinosaurs. Some top 24 feet tall. 

Visitors to the exhibit travel to the imaginary Isla Nublar, the setting of the movies “Jurassic Park” and “Jurassic World,” where they can meet a Tyrannosaurus rex, a brachiosaurus and a velociraptors face-to-face, along with other dinosaurs. At the Gentle Giants Petting Zoo, visitors can interact with a few more dinos and even “pet” one. 

One unique aspect of the “Jurassic World” exhibit: organizers worked with dinosaur expert Jack Horner, who discovered the first fossilized dinosaur embryos and led research into how different species of dinosaurs may have cared for their young. 

The goal was to make sure the science behind the exhibit was as accurate as possible. The exhibit has several hands-on activities that can teach visitors about how paleontologists study the dinosaurs. There’s also a guide for educators who want to teach their students more about the prehistoric reptiles.

Horner had another connection to the movie-inspired exhibit – he was the inspiration for the character of Alan Grant in “Jurassic Park.” He also served as a technical advisor on all of the movies.

The animatronic dinosaurs were created by The Creature Technology Co., which also worked on the “Walking With the Dinosaurs” arena shows.  

The American exhibit is nearly double the size of the previous version, which appeared in Melbourne, Australia until early October. More interactive and science-based activities were added, as well as a velociraptor training paddock like the one used in the movie “Jurassic World.”

The exhibit will be open in Philadelphia until April 23, 2017.

'Jurassic World' comes alive at Philadelphia exhibit

Hurricanes heading for Northeast U.S. according to studies. The northeast coast of the United States has historically been safer from the worst of hurricanes experienced in the southeast. But new research shows that more powerful hurricanes may begin hitting northeast at an increased rate due to shifting weather patterns.

For the past hundred years, hurricanes usually form in the western Caribbean and move north up the east coast. By the time they have reached the northeast, the storms usually have lost much of their potency. But according to a study from <a href="https://www.dur.ac.uk/">Durham University</a>, UK, this traditional track is shifting due to expanding atmospheric circulation belts caused by increased carbon dioxide emissions.

The study, led by Dr. Lisa Baldini and published in <a href="http://www.nature.com/srep/">Scientific Reports</a>, reconstructed hurricane rainfall for the western Caribbean dating back 450 years. The team analyzed the chemical composition of a stalagmite from a cave in Belize, Central America and found that the average number of hurricanes at the site decreased over time. But when compared to hurricane records in Bermuda and Florida, the date indicated storms were not occurring less frequently; they were just moving to the north. 

The researchers also noted a decrease in hurricane activity in the Western Caribbean beginning in the late 1800s during the industrial revolution. During this time, sulfate aerosol emissions increased drastically which caused a cooling of the Northern Hemisphere that should have pushed hurricane tracks southward. But rising amounts of atmospheric carbon dioxide overrode the effect, which expanded the tropical circulating air pattern known as the Hadley cell. This ultimately pushed hurricane tracks northbound. 

If carbon dioxide and aerosol emissions continue at their current rate, hurricanes could shift even further north, posing a significant threat to east coast cities that have not prepared for such powerful storms. 

According to Baldini, “since the 19th Century, this shift was primarily driven by human-made emissions and if these emissions continue this will result in more frequent and more powerful storms affecting the financial and population centers of the United States. Given the devastation caused by Hurricane Sandy, it is important that plans are put in place to protect against the effects of similarly destructive storms which could potentially occur more often in the future.”

Scientists studying a temporary slowdown of rising global mean surface temperature think they’ve found the reason behind it: an ocean heat sink.

From 1998 until 2013, the global mean surface temperature of the Earth appears to have slow its steady climb, a trend dubbed the “global warming hiatus,” scientists said – though they preferred the term “global warming slowdown” to avoid confusion.

So Dr. Xiao-Hai Yan of the <a href="http://www.udel.edu/">University of Delaware</a> and Dr. Tim Boyer of the <a href="http://www.noaa.gov/">National Oceanic and Atmospheric Administration</a> worked with a team of scientists from <a href="https://www.nasa.gov/">NASA</a>, the <a href="https://ncar.ucar.edu/">National Center for Atmospheric Research</a>, <a href="http://www.washington.edu/">University of Washington</a>, <a href="https://scripps.ucsd.edu/">Scripps Institution of Oceanography</a> as well as an independent consultant to take a closer look at the phenomenon to try and determine why the “hiatus” had occurred. 

The researchers found that the ocean may have played a larger role than previously believed in absorbing atmospheric heat during those years.

The scientists came to their conclusion after exchanging their past research into the subject and looking at what climate data was collected during those years, though they admitted the slowdown was too complex to nail down one specific cause.

However, the ocean acting as a heat sink is the most logical explanation, because it is so large, the scientists said. It is also supported by their previous research, Yan said.

For example, monitoring of coastal waters showed that those areas of the ocean warmed as global surface temperatures rose more slowly, the same research team reported in a 2015 paper. These waters warmed three times more than the open oceans did, Yan said.

Figuring out the cause of the global warming slowdown is vital, the researchers said, because it will help climate scientists better map out what climate change may look like in the next few decades. 

They also called for continued monitoring of ocean temperatures globally so that climate scientists can gain a better understanding in the role played by the ocean in global warming. If possible, the ocean temperature monitoring system should be expanded into deep waters to see how climate change is affecting them as well, the scientists said.

Scientists identify most environmentally friendly cereal cropping process

Agricultural methodologies selected for use in cereal cropping can have a significant impact on global warming and eutrophication. Until now, little research had been done to quantify the difference in environmental ramifications for each process. 

Novozymes, in collaboration with <a href="http://www.au.dk/en/">Aarhus University</a> and the <a href="http://www.ku.dk/english/">University of Copenhagen</a> analyzed the different consequences of these systems in a report titled “Environmental Life Cycle Assessment of Danish Cereal Cropping Systems” published by the DCA (<a href="http://dca.au.dk/en/">Danish Centre for Food and Agriculture</a>). 

The team used six different cereal cropping systems including winter wheat or spring barely, different sowing times, various uses of catch crops, and varied ways of handling the straw. Various environmental factors were taken into consideration including greenhouse gas emissions, grain yield, straw yield, carbon storage, land use, and loss of nutrients to the environment. Researchers particularly focused on how the cereal straw was utilized and if it was incorporated into the soil or used for co-production of bioethanol, biogas, and/or bioelectricity. 

The results showed that the best method of all with the smallest environmental impact was early sown winter wheat, where the straw gets removed every second year for use in biorefining. Early sown winter wheat nets more efficient straw and grain yield which in turn, takes up less land. In addition, in this system the straw can be used to replace gasoline, natural gas, and electricity. Thus, the early sowing of winter wheat scored the best grade when it comes to minimizing greenhouse gas emissions and environmental nutrient loss.

Following the results, the team emphasized the importance of viewing the full scope of the environmental effects of cereal production. “This collaboration has led to results that have given us a new and more nuanced angle on the sustainability of cereal production,” said Professor Bent T. Christensen from the Department of Agroecology at Aarhus University.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

</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.

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



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



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



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



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



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



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



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



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



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



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

<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>

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

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



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



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

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



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



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



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



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



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



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



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

Today’s Video of the Day from <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 <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."
