Italy’s Campi Flegrei has been restless again when it comes to earthquakes, and a new AI approach is helping scientists see what the ground is really doing. 



In a peer-reviewed study, researchers from <a href="https://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a>, along with colleagues at INGV Osservatorio Vesuviano and the <a href="https://www.international.unina.it/" target="_blank" rel="noreferrer noopener">University of Naples Federico II</a>, reanalyzed continuous seismic records. The team found more than four times as many small earthquakes between January 21, 2022, and March 20, 2025.



The researchers did not detect any direct sign of magma moving upward. Instead, they highlighted very shallow hybrid quakes tied to the hydrothermal system.



That fuller picture matters because small events reveal where the crust is stressed and how energy is moving through the volcanic field. With cleaner detections and sharper locations, scientists can track changes faster and judge when activity starts to cluster in risky ways.



<h2 class="wp-block-heading" id="h-clear-signals-urgent-stakes">Clear signals, urgent stakes</h2>



“Seismicity could change at any time, and that may be the most important thing about this study: this capability of getting a clear view is now operational,” said study co-author Greg Beroza, a geophysics professor at Stanford University.



The <a href="https://www.earth.com/news/supervolcano-campi-flegrei-naples-italy-solfatara-crater-phlegraean-fields-signs-of-waking-up/">caldera</a> sits within the Neapolitan area, where more than half a million people live and work. That density means even modest shaking or ground movement can disrupt daily life, strain buildings, and complicate evacuations.



History shows why clarity is essential. During the 1982-1984 crisis, uplift and persistent earthquakes damaged structures across Pozzuoli. A major analysis documented that the events triggered the evacuation of about 40,000 people.



<h2 class="wp-block-heading" id="h-ai-turns-noise-into-earthquake-signals">AI turns noise into earthquake signals</h2>



The team trained a machine learning workflow on continuous waveforms and used it to scan years of data consistently. That created one catalog rather than a patchwork of methods, so patterns stand out instead of becoming blurred.



AI did more than count earthquakes. The workflow sharpened event locations and magnitudes, turning noisy curves into clean signals that line up with mapped features and known hot zones. 



That is the kind of precision emergency managers need when activity jumps in hours, not weeks. One payoff is a much clearer view of the caldera’s thin ring shaped structures and shallow faults. 



Those features organize the small quakes and help separate background rumble from changes that could matter for public safety.



<h2 class="wp-block-heading" id="h-volcano-under-quiet-strain">Volcano under quiet strain</h2>



Campi Flegrei is a large caldera, the broad depression left by past eruptions, ringed by faults and dotted with old vents and fuming ground. It is not a single cone, it is a field where different parts can wake up at different times.



The region breathes over years through uplift and subsidence known as bradyseism. Those slow vertical motions have been recorded for centuries and often line up with swarms of small earthquakes.



In the new catalog, most activity sits at very shallow depths and traces a narrow ring fault system consistent with surface features and the zone now rising. 



The authors reported no direct signature of magma rising toward the surface in this interval. This lowers near-term eruption concern but does not remove the need for close watching.



<h2 class="wp-block-heading" id="h-faults-reveal-hidden-stress">Faults reveal hidden stress</h2>



Faults are breaks in rock that slip when stress overcomes strength, and their length and orientation constrain how big an earthquake could be. When small <a href="https://www.earth.com/news/earthquakes-and-flood-zones-hidden-risks-in-the-pacific-northwest/">quakes</a> line up along a longer fault, planners can bound the upper size of plausible events rather than guess in the dark.



Seeing faults crisply also helps compare present unrest with past episodes. Shaking that migrates onto a new segment or clusters at the edge of the ring may signal a change in how the system stores and releases pressure.



Those signals are not predictions by themselves. They are inputs to models that weigh where stress is building, how close rocks are to failure, and what level of shaking the built environment can handle.



<h2 class="wp-block-heading" id="h-ai-refines-risk-planning">AI refines risk planning</h2>



Near real-time detections let observatories update maps of active zones as conditions evolve. That supports decisions like where to inspect bridges, how to stage ambulances, or when to test public alerts before a busy weekend.



Sharper locations and <a href="https://www.earth.com/news/can-we-detect-major-earthquakes-months-in-advance/">magnitudes</a> also help engineers validate expected shaking levels against what instruments record in town. With that feedback loop, officials can refine microzonation, revisit building priorities, and tune maintenance schedules before the next swarm.



Past experience is a warning here. During 1982-1984, the harbor shallowed and commerce paused, schools closed, and the government approved new housing to relocate residents. 



Planning for unrest is not only about eruptions, it is about everyday disruptions that stack up when the ground keeps moving.



<h2 class="wp-block-heading" id="h-ai-helps-not-predicts">AI helps, not predicts</h2>



The present results point to pressure within a shallow system, not direct <a href="https://www.earth.com/news/magma-layer-keeps-the-yellowstone-supervolcano-dormant/">magma</a> rise, during 2022-2025. That aligns with other independent work that has argued for pressure buildup and evolving stress in the crust during long stretches without eruption.



Unrest can still change quickly. More small quakes could organize into tighter clusters, or uplift rates could shift, and those changes would be visible fast with the new tools.



AI does not replace dense earthquake monitoring or local expertise. It helps analysts keep up when data surge, flag subtle changes that a human might miss after a long night, and focus attention on the signals that matter most.



The study is published in the journal <a href="https://www.science.org/doi/10.1126/science.adw9038" target="_blank" rel="noreferrer noopener">Science</a>.

AI detects earthquake surge beneath Europe’s most dangerous volcano

Italy’s Campi Flegrei has been restless again when it comes to earthquakes, and a new AI approach is helping scientists see what the ground is really doing. In a peer-reviewed study, researchers from Stanford University, along with colleagues at INGV Osservatorio Vesuviano and the University of Naples Federico II, reanalyzed continuous seismic records. The team found more than four times as many small earthquakes between January 21, 2022, and March 20, 2025. The researchers did not detect any direct sign of magma moving upward.

A team of researchers at the <a href="http://www.gatech.edu/">Georgia Institute of Technology</a> have transformed crab shells and tree fibers into a material that could potentially replace flexible plastic film packaging.

The new material is made by spraying multiple layers of chitin from crab shells and cellulose from trees to create a flexible film similar to the plastic film that is used to keep food fresh.

Study co-author J. Carson Meredith is a professor in Georgia Tech's School of Chemical and Biomolecular Engineering.

“The main benchmark that we compare it to is PET, or polyethylene terephthalate, one of the most common petroleum-based materials in the transparent packaging you see in vending machines and soft drink bottles,” said Professor Meredith. 

“Our material showed up to a 67 percent reduction in oxygen permeability over some forms of PET, which means it could in theory keep foods fresher longer.”


Cellulose and chitin are the most abundant natural biopolymers on the planet. The team devised a way to suspend cellulose and chitin nanofibers in water while spraying them onto a surface in alternating layers. Once the material has dried, it is strong, flexible, transparent, and compostable.

“We had been looking at cellulose nanocrystals for several years and exploring ways to improve those for use in lightweight composites as well as food packaging, because of the huge market opportunity for renewable and compostable packaging, and how important food packaging overall is going to be as the population continues to grow,” said Professor Meredith.

The new material will improve upon the effectiveness of conventional <a href="https://www.earth.com/news/adidas-committed-recycled-plastic/">plastic packaging</a> because of its crystalline structure, which will keep oxygen from passing through and keep food fresher.

“It's difficult for a gas molecule to penetrate a solid crystal, because it has to disrupt the crystal structure,” explained Professor Meredith. “Something like PET on the other hand has a significant amount of amorphous or non-crystalline content, so there are more paths easier for a small gas molecule to find its way through.”


With the amount of cellulose and chitin-rich byproducts already available, there is probably enough material to make this flexible packaging alternative a reality, according to Professor Meredith.

But first, a cost effective manufacturing process needs to be developed, as well as methods to mass produce chitin. Additionally, more research is needed to improve the material's ability to block water vapor.

The study is published in the journal <a href="https://pubs.acs.org/journal/ascecg">ACS Sustainable Chemistry and Engineering</a>.

New project will fly into wildfire smoke to study its composition. This summer, researchers will conduct the largest, most comprehensive survey of <a href="https://www.earth.com/news/wildfires-western-united-states/">wildfire</a> smoke ever attempted. 

The <a href="https://www.nsf.gov/news/news_summ.jsp?cntn_id=295892&amp;WT.mc_id=USNSF_51&amp;WT.mc_ev=click">National Science Foundation</a> (NSF) reported on the new venture and the project is sponsored by NSF funding. 

Researchers from five different universities and the <a href="https://ncar.ucar.edu/">National Center of Atmospheric Research </a>will take part in 15 to 20 six hour observational smoke flights using a four-engine C-130 research aircraft.

It’s all part of a project called the Western Wildfire Experiment for Cloud Chemistry, Aerosol Absorption, and Nitrogen, or WE-CAN, the goal of which is to gain an in-depth understanding of how smoke impacts the environment.

With the aid of 30 scientific instruments and 18 scientists in the air along with a team on the ground, WE-CAN will fly into clouds of smoke and collect data on chemical composition and the smoke’s travelling patterns.  

Even though around <a href="https://www.nationalgeographic.com/environment/natural-disasters/wildfires/">100,000 wildfires clear millions of acres</a> of land every year, there have few research efforts dedicated to understanding wildfire smoke. 

“What we are doing in WE-CAN is much more systematic,” Emily Fischer, a member of the WE-CAN research team, told NSF. “We will start as close as we can to the fires and track the smoke for 12 to 24 hours. That's when a lot of the chemical evolution happens. We have very few existing samples of this evolution in the atmosphere.”

According to the NSF WE-CAN news release, the researchers want to answer questions like what is the smoke made of, how does it change over time, and how does is affect clouds to name a few. 

“These researchers are following the transport and transformation of the plume of gases and aerosols emitted by wildfires to understand the chemical changes they undergo over time, how their properties might vary, and their impacts on human health and the environment,” Sylvia Edgerton, a program director in NSF's Division of Atmospheric and Geospace Sciences, told the NSF. 

The data collected on these flights could help future research on air quality, weather, and the impact of wildfire smoke on health.

The remains of a baby snake found preserved in amber from Myanmar are estimated to be 99 million years old. The fossil, which is the first of its kind, is around two inches in length and has 97 vertebrae.

The experts also examined a second piece of amber containing what appears to be a fragment of skin from an adult <a href="https://www.earth.com/news/risk-death-snake-bites/">snake</a>. The specimens were obtained from an amber deposit in the Hukawng Valley of Myanmar, and date back to the early Late Cretaceous period.

Study co-author Dr. Lida Xing is a paleontologist from the <a href="http://en.cug.edu.cn/">China University of Geosciences</a> in Beijing. “The fossil is the first baby snake and the oldest baby snake to yet be found,” said Dr. Xing. 

Michael Caldwell is a snake paleontologist at the <a href="https://www.ualberta.ca/">University of Alberta</a> who also co-authored the study. According to the <a href="https://www.nytimes.com/">New York Times</a>, Dr. Caldwell said that, prior to this study, a fossilized baby snake has never been found - even in the rock fossil record.

Dr. Xing told the Times that hundreds of thousands of amber pieces had been retrieved from this region of Myanmar, but no snake was ever recovered.

When the specimen was first found, the creature inside was thought to be a centipede or a millipede because the head was missing. 

Micro-CT scans revealed that the fossil was that of a baby snake, and the paleontologists named the new species Xiaophis myanmarensis. It is unclear whether the snake was an embryo or a newborn, but tiny bones alongside a large spinal cord tube suggest that the baby was still developing.

“No one has ever seen a fossilized baby snake of any kind whatsoever. And having this one be nearly a hundred million old is really quite amazing,” Dr. Caldwell told <a href="https://www.nationalgeographic.com/">National Geographic</a>.

“Whether or not these early snakes were giving live birth, which is common in modern snakes, or whether they were hatching from eggs, is unclear. But based on size and developmental stage, this thing was a newborn.”

The study authors explained that the new snake fossils represent “a greater ecological diversity and global distribution of Late Mesozoic snakes, and more specifically, Cretaceous snakes, than was previously understood.”

The research is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

New plant breeding technologies have the potential to make fruits and vegetables more appealing to the eyes and also to the taste buds. A pair of food experts is reporting that the produce of the future could have enhanced colors, shapes, and sizes, along with improved health benefits.

Study co-author Andrew Allan is a food researcher at the New Zealand science institute <a href="https://www.plantandfood.co.nz/">Plant &amp; Food Research</a>.

“Novelty drives a lot of first time purchasing,” said Allan. “If the experience is good, then the consumer will purchase again. Choice is key - there is no risk with more choice.”

The researchers explained that fast breeding with CRISPR-Cas9 gene editing does not require the addition of a new DNA sequence, which is often the case with genetically modified crops. Instead, this technology allows scientists to edit existing genes. There is focus, in particular, on transcription factor genes called MYBs that control many of the key consumer traits in plants.

“MYBs often regulate the compounds that generate a fruit or vegetables' 'wow’ factor - its color,” said Allan. “These compounds are also associated with important health benefits such as lowering cardiovascular disease or acting as vitamins. By using MYBs to elevate these compounds to create a richer color, we can make produce both more appealing to consumers and more beneficial for the human diet.”


Editing MYBs can also transform produce beyond the surface. For example, some fruits and vegetables such as <a href="https://www.earth.com/news/best-wash-pesticides-apples/">apples</a> and potatoes have nutrients that are concentrated in the skin. Scientists can now modify MYBs to create produce with a consistent concentration of vitamins in every bite.

The breeding technology is also being used to modify the flavor and texture of produce, and Allan is excited by what this could mean for the future of our supermarkets. He said that this could be “the next green revolution, with more product choice for developed countries, greater yields for less developed countries, and more growing options for climate resilience.”

The study is published in the journal <a href="https://www.cell.com/trends/plant-science/home">Trends in Plant Science</a>.

It’s a well-known fact that we currently know less about the <a href="https://www.earth.com/news/carbon-storage-ocean-floor/">ocean floor</a> than we do about the surface of the moon. Our oceans are the largest and least explored environments on the planet, and scientists estimate they may contain up to a million species that are yet to be discovered. Still, deep-ocean dives in specially designed submersibles frequently turn up new species. Many of these organisms are soft-bodied – similar to jellyfish, squid, and octopuses – which makes them difficult to capture for study without harming them.

Luckily, a new device has just been developed by researchers at <a href="https://wyss.harvard.edu/">Harvard University’s Wyss Institute</a>, <a href="https://www.seas.harvard.edu/">John A. Paulson School of Engineering and Applied Sciences</a> (SEAS), and <a href="https://www.radcliffe.harvard.edu/">Radcliffe Institute for Advanced Study</a>. This device can capture soft-bodied species for study inside a folding polyhedral enclosure, before letting them go unharmed. The research is reported in <a href="http://robotics.sciencemag.org/">Science Robotics</a>.

The device was designed and built by Zhi Ern Teoh, Ph.D., and consists of five 3D-printed polymer “petals” attached to rotating joints that are linked together to create a scaffold. A motor applies torque to the point where the petals meet, resulting in the entire structure rotating about the joints and folding into a hollow dodecahedron – which is a twelve-sided 3D shape, almost like a rounded box. This device has been named the Rotary Actuated Dodecahedron (RAD). 

The RAD sampler was tested at the Mystic Aquarium in Mystic, CT, where it successfully collected and released moon jellyfish underwater. It was then modified to withstand open ocean conditions, and mounted on an underwater remotely-operated vehicle (ROV) provided by the <a href="https://www.mbari.org/">Monterey Bay Aquarium Research Institute</a> in Monterey, CA. The device was tested in the field at depths of 500-700 meters, using the ROV’s manipulator arm and a human-controlled joystick to operate the RAD. In the field, the team was able to capture soft organisms like squid and jellyfish in their natural habitats, and then release them unharmed. 

“The RAD sampler design is perfect for the difficult environment of the deep ocean because its controls are very simple, so there are fewer elements that can break. It’s also modular, so if something does break, we can simply replace that part and send the sampler back down into the water,” says Teoh. “This folding design is also well-suited to be used in space, which is similar to the deep ocean in that it’s a low-gravity, inhospitable environment that makes operating any device challenging.”

Teoh is currently working on a more rugged version of the RAD to be used in heavy-duty underwater tasks – such as marine geology. Robert Wood, Ph.D., a Founding Core Faculty member of the Wyss Institute, explains how the benefits of this device go beyond its practical use: “Our group’s collaboration with the marine biology community has opened the door for the fields of soft robotics and origami-inspired engineering to apply those technologies to solve problems in an entirely different discipline, and we are excited to see the ways in which this synergy creates novel solutions.”

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) technology has revolutionized gene editing and allows scientists to make targeted cuts to DNA. 

CRISPR uses the Cas9 enzyme to do this and after target areas have been removed, the DNA repairs itself. 

The potential implications of CRISPR are massive as it could help eradicate genetic diseases, but there are still a wide range of ethical concerns about <a href="https://www.earth.com/news/public-opinion-gene-editing/">how far is too far when it comes to gene editing</a>. 

Now, a new study has found that CRISPR gene-editing can create large-scale unwanted DNA deletions that go by undetected. 

Researchers from the <a href="https://www.sanger.ac.uk/">Wellcome Sanger Institute</a> conducted the study which was published in the journal Nature Biotechnology. 

Because CRISPR involves cutting and rearranging DNA, the researchers found that this can cause mixed up rearrangements as the DNA attempts to repair itself and make unwanted deletions. 

“The cell will try to stitch things back together,” said Allan Bradley, the leader of the study. “But it doesn’t really know what bits of DNA lie adjacent to each other.”

Bradley and his team found that CRISPR was deleting strands of DNA that were thousands of letters long and because of the amplifying methods used to test the success of gene edits, these large-scale cuts went unnoticed. 

These unforeseen ramifications put a damper on CRISPR’s potential and calls for more stringent testing among researchers. 

There are some companies that are on the lookout for large-scale deletions, including eGenesis and Intellia. eGenesis is using gene editing to engineer pig organs so that they are safe for transplant. Itnellia is using CRISPR to study mouse livers but keeping an eye out for large-scale deletions is a routine part of their process.

Gene editing could remove the risk of genetic conditions and diseases but it’s also a process that is not without its flaws as this study shows, and more attention to these large-scale edits is needed by gene editing scientists.

While investigating the possible existence of a massive planet Beyond Pluto, scientists discovered that Jupiter has 12 more moons than previously realized. While 11 of these moons found orbiting the planet are considered to be normal, there is one that the experts are calling an “oddball.”

The research team, led by Scott S. Sheppard of the <a href="https://carnegiescience.edu/">Carnegie Institution for Science</a>, first observed a giant object in our solar system in 2014, which is now referred to as Planet X or Planet Nine.

“Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant Solar System objects, so we were serendipitously able to look for new moons around Jupiter while at the same time looking for planets at the fringes of our Solar System,” said Sheppard.

Gareth Williams at the <a href="https://www.minorplanetcenter.net/iau/mpc.html">International Astronomical Union's Minor Planet Center</a> explained: “It takes several observations to confirm an object actually orbits around Jupiter. So, the whole process took a year.”

Nine of the newly-discovered moons are part of a distant collection of moons that orbit in the opposite direction of Jupiter's spin rotation. They are believed to have originated from larger bodies before colliding with asteroids, and take about two years to orbit the <a href="https://www.earth.com/news/dwarf-planet-ceres-water/">planet</a>.

[caption id="attachment_1216453" align="aligncenter" width="300"]<a href="https://www.earth.com/wp-content/uploads/2018/07/Jupiter.png"><img class="size-medium wp-image-1216453" src="https://www.earth.com/wp-content/uploads/2018/07/Jupiter-300x187.png" alt="" width="300" height="187" /></a> Image Credit: Roberto Molar-Candanosa, courtesy of Carnegie Institution for Science[/caption]

Two of the new moons have been found to orbit in the prograde, or same direction as the planet's rotation, within a closer group of moons. Similar orbital distances and angles suggest that this pair may be fragments of a larger moon that was broken apart, and they circle the planet in just under a year.

“Our other discovery is a real oddball and has an orbit like no other known Jovian moon,” said Sheppard. “It's also likely Jupiter's smallest known moon, being less than one kilometer in diameter.”

This moon, which takes about one and a half years to orbit Jupiter, is more inclined to the prograde group of moons - yet has an orbit that crosses the outer retrograde moons. For this reason, the atypical moon is more prone to collisions with both prograde and retrograde moons.

“This is an unstable situation,” said Sheppard. “Head-on collisions would quickly break apart and grind the objects down to dust.”

The incredible findings of the study modify the total number of moons orbiting Jupiter to 79, which is the most of any planet in our Solar System.

Two Japanese volcanoes, Aira caldera and Kirishima, a more than 13 miles apart. But scientists are now realizing that the two are much more closely connected than anyone suspected.

Now, geologists have confirmed that the pair of volcanoes are connected by a vast subterranean network of magma. 

Their first concrete evidence came during the 2011 eruption of Kirishima.

"We observed a radical change in the behavior of Aira before and after the eruption of its neighbor Kirishima," said Dr. Elodie Brothelande, a researcher at the <a href="https://welcome.miami.edu/">University of Miami</a>. "The only way to explain this interaction is the existence of a connection between the two plumbing systems of the volcanoes at depth."

Brothelande led the team of geoscientists from the university’s <a href="https://www.rsmas.miami.edu/">Rosenstiel School of Marine and Atmospheric Science</a> and <a href="https://www.fiu.edu/">Florida International University</a> as they analyzed data collected by 32 geopositional satellite stations located near the Japanese volcanoes.

Before Kirishima erupted, scientists studying Aira found that the caldera had stopped growing. They believed the volcano was at rest – until magma started flowing at Kirishima. Now, the GPS data has confirmed what experts suspected: the two volcanoes were connected to the same pool of magma, and Kirishima’s eruption interrupted the flow to Aira.

It also lends new evidence to a long-lived hypothesis, that the eruption of one volcano can affect other nearby volcanoes. Volcanic activity elsewhere in the world has long pointed to this, but until now, there was no solid proof of such a relationship between two or more volcanoes.

That means that when scientists begin observing sudden changes at one volcano, they should look for other changes nearby that could indicate an eruption.

"Eruption forecasting is crucial, especially in densely populated volcanic areas," said Brothelande. "Now, we know that a change in behavior can be the direct consequence of the activity of its neighbor Kirishima."

Cardiovascular disease is taking a growing toll on India, especially among young adults and rural populations, a new national study has found.

Ischemic heart disease, which develops as arteries in the heart grow narrow, has increased rapidly among Indians from 30 to 69, with rural areas outpacing cities between 2000 to 2015, the researchers discovered. In northeastern India, rates of premature stroke deaths also rose to about three times the national average – though much of the country saw a decrease.

Dr. Prabhat Jha, who runs the Centre for Global Health Research at <a href="http://www.stmichaelshospital.com/">St. Michael’s Hospital</a> in Toronto, led the first-of-its-kind study of Indian health.

"The finding that cardiac disease rose nationally in India and that stroke rose in some states was surprising," Jha said. "This study also unearthed an important fact for prevention of death due to cardiovascular disease. Most deaths were among people with previously known cardiac disease, and at least half were not taking any regular medications."

Up until this study, most scientific research into cardiovascular disease in India has taken the form of small, local studies or modeling based on imprecise research. But cardiovascular disease is one of the major causes of death globally, especially ischemic heart disease and stroke. 

The researchers launched the study of India’s cardiovascular disease and death rates as part of the <a href="http://www.cghr.org/projects/million-death-study-project/">Million Death Study</a>, a global effort to examine causes of premature death.

Census takers with special medical training traveled throughout India, asking people about family members’ deaths and conducting “verbal autopsies” to determine the most likely causes.

"Making progress in fighting the leading cause of death in India is necessary for making progress at the global level," Jha said. "We demonstrated the unexpected patterns of heart attack and stroke deaths. Both conditions need research and action if the world is going to achieve the United Nations Sustainable Development Goal of reducing cardiovascular mortality by 2030."

The study has been published in <a href="http://www.thelancet.com/journals/langlo/article/PIIS2214-109X(18)30242-0/fulltext">The Lancet Global Health</a>.

Researchers have discovered what may be the Earth’s only mass cooling event, and it might have wiped out three-quarters of marine life on the planet. The mass extinction event has been linked to tiny algae, the team said.

The team, studying ancient ocean sediments discovered in Nevada, found that the algae population may have exploded during the Late Ordivician period. That in turn may have caused the atmosphere to cool rapidly, leading to a massive die-off of marine species, said Dr. Ann Pearson of Harvard University, one of the study’s co-authors.

“The coincidence of this community shift with a large-scale marine transgression increased organic carbon burial, drawing down [carbon dioxide] and triggering the Hirnantian glaciation,” the researchers wrote.

The team found that the samples of limestone and shale from Nevada, sediments from an ancient ocean, contained compounds that come from production of chlorophyll. 

But the amount of the compounds that the tiny algae produced nearly quintupled over just a few million years, the team found. 

That suggests that the algae population exploded – sucking up carbon dioxide and producing oxygen. In the process, excess carbon would have been trapped in the ocean floor, cutting atmospheric carbon levels drastically and perhaps triggering glacial expansion.

During the Late Ordivician from about 447 to 444 million years ago, a series of extinction events known as the “big five” took place. One of the events brought about the end of a majority of the sea-dwelling species at that time. An ice age that lasted half a million to 1.5 million years followed.

Most microalgae – including cyanobacteria, formerly known as blue-green algae – use photosynthesis to grow, processing sunlight, carbon dioxide and a few other nutrients.

Dr. Richard Pancost of the <a href="http://www.bristol.ac.uk/">University of Bristol</a> told <a href="https://eos.org/">Earth and Space Science News</a> that the study shows how algae may be an important part of carbon regulation on Earth.

“It is a fascinating hypothesis based on some exciting new data,” said Pancost, who was not involved with the study.

The study has been published in the journal <a href="https://www.nature.com/articles/s41561-018-0141-5">Nature Geoscience</a>.

Scientists: tiny algae triggered ancient mass extinction

Researchers have discovered what may be the Earth’s only mass...

Researchers at <a href="https://vt.edu/">Virginia Tech</a> are using methods similar to weather forecasting to anticipate the growth rates of trees. Changes in temperature, water, and atmospheric carbon concentrations can all affect forests, and ecological forecasting is aimed at predicting the future extent of these impacts.

The research expands on two previous investigations funded by the <a href="https://www.usda.gov/">U.S. Department of Agriculture</a>. 

The first study, known as PINEMAP, was based on <a href="https://www.earth.com/news/amber-fossil-frogs-tropical-forests/">forest</a> growth data collected by hundreds of researchers over the past 35 years. Using this data, mathematical models were developed to estimate how pine forests may respond to climate change.

The second project was led by R. Quinn Thomas, an assistant professor of Forest Dynamics and Ecosystem Modeling in Virginia Tech's Department of Forest Resources and Environmental Conservation. This study was focused on identifying uncertainties in how climate models predict the influence of forest ecosystems on temperature and precipitation patterns.

The similarities between these two projects prompted Thomas to design an additional study aimed at forecasting forest productivity through the middle of the 21st century.

“I realized that we could use the past to inform the future,” said Thomas. “Historical observations on tree growth and weather can be fed into a mathematical model describing how forests grow, making it more accurate over time. This is similar to how weather forecasts are updated as new weather data becomes available.”

Thomas and his team used the findings from both projects to develop an analytical framework that can be combined with predictions from climate models to generate a future ecological forecast.


The model, which represents the process of forest growth, is provided with data on the diameter of trees, the number of leaves produced in a given year, and how much water is evaporated from the forest.

Next, statistical methods similar to those used in weather forecasting are applied to the model, which is adjusted to account for uncertainties.

“This new study allows us to put a level of certainty or uncertainty on those estimates, so we're able to say ‘there is an 80-percent chance that the forest will grow faster over the next few decades,’” explained Thomas.

The research was focused specifically on loblolly pine plantations, an important source of timber for the Southeastern United States.

“We found that in this region, there will be about a 30-percent increase in productivity between now and the middle of the century,” said Thomas. “The largest gains are forecasted in Virginia, and there's high confidence that we'll see that increase in productivity there. In Florida, however, the increase in productivity is expected to be lower, and we may even see a decline in productivity between now and mid-century.”


Thomas pointed out that there are some uncertainties across varying regions of the Southeast. Regardless, the new method of ecological forecasting seems promising.

“I'm excited to see how this particular forecast does over the next few decades and to update it as we learn more about how forests work and as more data become available,” said Thomas. “Furthermore, this system sets a foundation for this process to be used in the forestry industry to predict other aspects besides productivity.” 

“Beyond that, the study is an example of how ecological scientists are starting to think about becoming forecasters in a way similar to how we've been forecasting the weather, and that's very exciting.”

The research is published in the journal <a href="https://esajournals.onlinelibrary.wiley.com/journal/19395582">Ecological Applications</a>.

Experts can now forecast forest growth much like weather

Researchers at Virginia Tech are using methods similar to weather...

The analysis of a neutrino, also known as a ghost particle, that blasted into Antarctic ice last year has just opened up an entirely new approach to space exploration. NASA’s Fermi Gamma-ray Space Telescope has traced the origin of the mysterious particle to a galaxy 3.7 billion light years away.

Neutrinos are named for being electrically neutral and also for their incredibly small mass, which was long believed to be zero. On the subatomic scale, the gravity of a neutrino is extremely weak and these particles normally pass through matter completely undetected at nearly the speed of light.

The presence of this particular neutrino was detected last September by <a href="https://icecube.wisc.edu/">IceCube</a>, a sensor buried about two kilometers beneath the ice near the Amundsen-Scott South Pole Station. 

The tremendous force behind the particle as it hit the ice indicated that it came from beyond our solar system. The neutrino struck the ice with the energy of about 300 trillion electron volts, according to <a href="https://www.nasa.gov/">NASA</a>, which is more than 45 times the energy that is generated by the most powerful particle accelerator on Earth.

Because cosmic rays are charged particles, powerful magnetic fields throughout space distort their trajectories. Neutrinos, on the other hand, have no charge and are unaffected by magnetic fields, which means their paths point almost directly to their source.

Once the trajectory of the neutrino was identified by IceCube, experts all over the world were alerted to look for flares or other outbursts in an effort to find its source. Ultimately, data from Fermi’s Large Area Telescope recognized accelerated gamma-ray emission that correlated with the rare neutrino interaction. 

The activity was coming from a type of galaxy known as a “blazar,” which has a supermassive black hole that blasts out streams of highly energetic particles in opposite directions. The term blazar is used when one of these streams is pointed directly toward the <a href="https://www.earth.com/video/what-exactly-is-a-near-earth-asteroid/">Earth</a>.

“Fermi’s LAT monitors the entire sky in gamma rays and keeps tabs on the activity of some 2,000 blazars, yet TXS 0506 really stood out,” explained NASA Postdoctoral Fellow Sara Buson. “This blazar is located near the center of the sky position determined by IceCube and, at the time of the neutrino detection, was the most active Fermi had seen it in a decade.”

The blazar known as TXS 0506 is around 3.7 billion light years from Earth, just to the left of the constellation Orion.

This is the first time scientists have ever detected a neutrino and identified its source. Detecting neutrinos, which are some of the most abundant substances on the planet, will provide scientists with a brand new way to explore the complex processes that are taking place in other galaxies billions of light years away.

Julian Osborne is a professor in the Department of Physics &amp; Astronomy at the <a href="https://le.ac.uk/">University of Leicester</a> and was part of a team that confirmed the blazar.

“This is literally a new way of seeing the universe,” Professor Osborne told <a href="https://www.theguardian.com/us">The Guardian</a>. “This really is the dawn of a new type of astronomy.”

The research is published in two separate papers in the journal <a href="http://www.sciencemag.org/">Science</a>.

<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.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

<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.

<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.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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



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



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



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

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;
