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.

Animals can feel empathy, new research shows. Having evolved as a social society that relies on strong community and familial bonds, humans have a remarkable ability to <a href="https://www.earth.com/news/humans-chimpanzees-exhibit-empathy/">empathize with the emotions and pain of others</a>. 

We wince when we see someone else get hurt or feel bad when our loved ones experience a loss. But now, for the first time, the ability to empathize and mirror another’s pain has been observed in animals.

When it comes to why we experience empathy, previous research has come up with a potential explanation. 

It’s theorized that the cingulate cortex, a region of the brain activated when we get hurt or experience pain, contains mirror neurons that are easily triggered when we see someone else get hurt. 

In other words, the same region activated by our own pain is also activated when it registers someone else’s pain. 

This theory has remained untested until now as it is impossible to record the activity of single human brain cells or disrupt brain activity in the cingulate cortex. 

To determine if the cingulate cortex is responsible for empathy, researchers from the <a href="https://nin.nl/">Netherlands Institute for Neuroscience</a> turned to rats. 

For the study, published in the journal Current Biology, the researchers monitored the brain activity of a rat as it watched a fellow rat receive a mild shock. 

Rats freeze in response to fear, and when a rat saw it’s neighbor rat get shocked, it also froze in fear showing that rats, similar to humans, experience empathy. 

What’s more, watching another rat experience something unpleasant activated the same cingulate cortex region of the brain that is theoretically triggered in humans who experience empathy. 

Both the rat receiving the shock and the rat watching had similar brain activity which confirms the theory that the cingulate cortex contains mirror neurons. 

The researchers also tested to see what happens when a rat’s cingulate cortex cells were suppressed. 

After injected a drug into the rat that hindered the activity of the cells in the cingulate cortex, the researchers found that rats no longer felt empathy or mirrored the pain and fear of another rat. 

The study sheds insight into the underlying mechanisms behind empathy and could help future studies working to understand certain disorders like psychopathy, which are characterized by a lack of empathy. 

“What is most amazing, is that this all happens in exactly the same brain region in rats as in humans,” said Christian Keysers, the lead author of the study. “We had already found in humans, that brain activity of the cingulate cortex increases when we observe the pain of others, unless we are talking about psychopathic criminals, who show a remarkable reduction of this activity.”

Research shows link between antimicrobial resistance and climate change. A collaborative study from the Institute of <a href="https://www.idsociety.org/policy--advocacy/infection-prevention-and-control/">Infection Control and Infectious Diseases</a>, <a href="https://www.umg.eu/">University Medical Center Göttingen</a> (UMG), and the <a href="https://www.mh-hannover.de/">Hannover Medical School</a> (MHH), has shown an association between antimicrobial resistance (AMR) and climate change. 

AMR was first linked to <a href="http://www.earth.com/news/climate-change-allergy-season-longer/">climate change</a> when researchers noticed that resistance increased as temperatures warmed in the U.S. The study set out to determine if explanatory strength of climate factors can predict an increase of AMR, even in regions with diverse healthcare systems and communities. The researchers used Europe as a case region.

The team studied 30 countries across Europe and found via data published by the <a href="https://ecdc.europa.eu/en/home">European Centre for Disease Prevention and Control</a> (ECDC) a widespread, six-year-long presence of carbapenem resistant Pseudomonas aeruginosa (CRPA), Klebsiella pneumoniae (CRKP), multiresistant Escherichia coli (MREC), and Methicillin resistant Staphylococcus aureus (MRSA).

The then looked at the correlation between AMR and seasonal temperatures in each region, paying close attention to potential healthcare and socioeconomic factors that could be at play. Researchers were able to link CRKP, MREC and MRSA to warm-season mean temperature. CRPA was linked to warm-season change in temperature.

"Our study identified a novel association between AMR and climatic factors in Europe,” Professor Simone Scheithauer of UMG and her colleagues explain. “These results reveal two aspects: climatic factors significantly contribute to the prediction of AMR in different types of healthcare systems and societies, while climate change might increase AMR transmission, in particular carbapenem resistance."

The authors continue, "While these results remain hypothetical as it is unknown if any causal association exists, future analysis of AMR and climatic developments is necessary to determine whether potential climate change effects on AMR become stronger."

The findings will be presented at the April 13th <a href="https://www.escmid.org/">European Congress of Clinical Microbiology &amp; Infectious Diseases</a> (ECCMID).

Why lightning really can strike twice. While experts have noted that <a href="http://www.earth.com/news/most-lightning-strikes-2018/">lightning</a> really can strike twice in the same place, the reason that a lightning channel is “reused” has remained unclear. But now, an international research team led by the <a href="https://www.rug.nl/?lang=e">University of Groningen</a> may have finally solved this mystery. 

By using the Low Frequency Array (LOFAR), a Dutch radio telescope consisting of thousands of antennas spread out over Northern Europe, the researchers were able to view the development of lightning flashes in unprecedented detail. 

The study revealed that the negative charges inside of a thundercloud are not all discharged in a single flash. Instead, some are stored inside structures that the experts refer to as needles. The researchers determined that a negative charge through these needles may cause a repeated discharge to the ground.

“This finding is in sharp contrast to the present picture, in which the charge flows along plasma channels directly from one part of the cloud to another, or to the ground,” said Professor Olaf Scholten.

Study first author Dr. Brian Hare explained that the reason why the needles have never been seen before lies in the “supreme capabilities” of LOFAR.

“These needles can have a length of 100 meters and a diameter of less than five meters, and are too small and too short-lived for other lightning detections systems.”

For their observations, the scientists used only the Dutch LOFAR stations, which cover an area of 3,200 square kilometers. They analyzed the raw time-traces as measured in the 30-80 MHz band. 

“These data allow us to detect lightning propagation at a scale where, for the first time, we can distinguish the primary processes. Furthermore, the use of radio waves allows us to look inside the thundercloud, where most of the lightning resides,” said Dr. Hare.

High-resolution 3D images of the lightning clearly showed a break in the discharge channel at a location where needles are formed. These appear to discharge negative charges from the main channel, which then re-enter the cloud. As a result, the reduction of charges in the channel causes the break. 

But then, once the charge in the cloud is built up again, the flow through the channel is restored and there is a second discharge of lightning. Based on this finding, lightning can strike in the same area repeatedly.

“The VHF emissions along the positive channel are due to rather regularly repeated discharges along previously formed side channels, the needles,” explained Professor Scholten. “These needles appear to drain the charges in a pulsed manner.”

“From these observations, we see that a part of the cloud is re-charged, and we can understand why a lightning discharge to the ground may repeat itself a few times,” said Dr. Hare.

The study is published in the journal <a href="https://www.nature.com/">Nature</a>.

The number of planets that could conceivably support life are identified by astronomers by their location in a “habitable zone,” which refers to the sweet spot in a solar system where a planet is close enough to its sun to <a href="https://www.earth.com/news/exoplanet-proxima-centauri-life/">have liquid water</a>. 

For a planet to be located in a habitable zone, it needs to be at just the right proximity from its star. If it’s too close the water evaporates, but if it’s too far everything freezes (think Pluto). 

In a new study, researchers from the <a href="https://www.ucr.edu/">University of California, Riverside</a> found that the habitable zone of a solar system may be narrower than previously realized. 

Now, researchers estimate that a habitable zone capable of supporting complex life is half the size it was previously thought to be. 

The study shows that most planets in a habitable range would be unable to support anything but single-cell microbes and that a thick layer of toxic gases like carbon monoxide would make human exploration or complex life impossible. 

The researchers published their findings in the <a href="https://iopscience.iop.org/article/10.3847/1538-4357/ab1d52#references">Astrophysical Journal</a>. 

“Imagine a ‘habitable zone for complex life’ defined as a safe zone where it would be plausible to support rich ecosystems like we find on Earth today,”  said Timothy Lyons, a co-author of the study. “Our results indicate that complex ecosystems like ours cannot exist in most regions of the habitable zone as traditionally defined.”

For the study, the researchers used computer models to simulate the climate, atmosphere, and photochemistry of different planets. 

A planet with liquid water farther away from its star likely indicates a massive amount of carbon dioxide at levels to potent for complex life to survive. 

“To sustain liquid water at the outer edge of the conventional habitable zone, a planet would need tens of thousands of times more carbon dioxide than Earth has today,” said Edward Schwieterman, the study’s lead author. “That’s far beyond the levels known to be toxic to human and animal life on Earth.”

Accounting for gas toxicity drastically reduced the habitable zone and if a planet is to support humans, it’s habitable zone is one-third what it was previously. 

Certain stars like Proxima Centauri have no planets capable of supporting life the models showed. 

The study models are already being used by the <a href="https://www.nasa.gov/">National Aeronautics and Space Administration </a>(NASA) to help determine which, if any, planets outside of our own solar system are worth exploring as potential candidates for supporting life. 

“Our discoveries provide one way to decide which of these myriad planets we should observe in more detail,” said Christopher Reinhard, a co-author of the study. “We could identify otherwise habitable planets with carbon dioxide or carbon monoxide levels that are likely too high to support complex life.”

The ocean has been doing us all a solid for decades. As human activity pumps out carbon dioxide headed for the planet’s atmosphere, the ocean absorbs it – but its role as a carbon dioxide sink may be causing irreparable harm.

The Earth’s seas absorb close to a third of the carbon dioxide humans are releasing into the atmosphere. That adds up to about 2.6 billion tons per year, according to the international team of researchers. 

"It’s a huge service the oceans are doing,” co-author Dr. Richard Feely of the <a href="https://www.noaa.gov/">National Oceanic and Atmospheric Administration</a> told the <a href="https://www.seattletimes.com/">Seattle Times</a>. “That significantly reduces global temperature.”

Carbon dioxide is produced by human activity that burns fossil fuels, like transportation, heating buildings, and producing electricity from coal and gas. Plants can convert the gas into oxygen and forests serve as a carbon dioxide sink, but deforestation and <a href="https://www.earth.com/news/tropical-regions-co2-increase/">drought</a> have made it impossible for Earth’s plant life to keep up with emissions.

Enter the ocean. The massive body of water that covers 70 percent of the planet’s surface has been taking in carbon, but at a cost.

Ocean acidification has been linked to CO2, and it is having a devastating effect on ocean life. Fish in coastal waters such as salmon and sharks have shown signs of <a href="https://www.earth.com/news/ocean-acidification-coastal-waters/">cognitive dysfunction</a> due to the more acidic seas, and <a href="https://www.earth.com/news/ocean-acidification-marine-ecosystems/">coral reefs and kelp forests</a> have been dying off. It changes how shellfish develop their skeletons. The ocean’s role as a carbon dioxide sink has also been linked to <a href="https://www.earth.com/news/co2-ocean-floor-dissolve/">damage to the seafloor</a>.

"The increasing load of carbon dioxide in the ocean interior is already having an impact on the shellfish industry, particularly along the U.S. West Coast,” Feely told the Times.

But the study shares a more dire prediction: the ocean will eventually reach its saturation point, though it’s at least a few decades away. That’s when those of us living above the surface may start feeling the effects of climate change that the seas have been shielding us from.

"At some point the ability of the ocean to absorb carbon will start to diminish," co-author Dr. Jeremy Mathis, also with NOAA, told <a href="https://mashable.com/">Mashable</a>. "It means atmospheric carbon dioxide levels could go up faster than they already are."

The study has been published in the journal <a href="http://science.sciencemag.org/content/363/6432/1193">Science</a>.

Organic electronics have been quickly gaining traction in the world of technology ever since the discovery of electrically conducting plastics and polymers. 

Organic light emitting diode displays are already on the market and have become more popular for televisions and cell phones and are also said to produce clearer images compared to LED displays.  

While organic electronics show a great deal of promise, they have yet to compete with other inorganic methods of conducting electricity in terms of efficiency, production, and manufacturing. Polymers and plastics don’t conduct as well as other materials. 

However, that may quickly change as researchers from the <a href="https://www.chalmers.se/en">Chalmers University of Technology </a>in Sweden have found a way to double the efficiency of organic electronics. The implications of this breakthrough could benefit organic light emitting displays, bioelectronics, and <a href="https://www.earth.com/news/plastic-solar-cells-absorb-sunlight/">plastic solar cells</a>. 

The research revolves around “double-doping” polymers. Most electronics today depend on inorganic semiconductors like silicon and doping helps enhance the conductivity of these materials. Doping is a process by which impurities are inserted into semiconducting materials. 

Doping is also required for organic electronics, and a redox reaction is what creates organic semiconductors. 

A <a href="http://www.chemistry.wustl.edu/~coursedev/Online%20tutorials/Redox.htm">redox reaction</a> is a common type of chemical reaction combining reduction and oxidation in which atoms gain and lose electrons, and this increases conductivity.

[caption id="attachment_1865166" align="aligncenter" width="700"]<a href="https://www.earth.com/wp-content/uploads/2019/01/solar-cell.jpg"><img class="wp-image-1865166" src="https://www.earth.com/wp-content/uploads/2019/01/solar-cell.jpg" alt="" width="700" height="1050" /></a> Image Credit: Johan Bodell/Chalmers University of Technology. The solar cell was supplied by Epishine AB.[/caption]

With organic semiconductors, an electron is added to a dopant molecule through the redox reaction, and this increases electrical conductivity. The more dopant molecules, the better the conductivity, but only up to a certain limit (called the efficiency limit). 

After a doped organic semiconductor reaches its efficiency limit, conductivity decreases. 

To improve the efficiency of organic semiconductors, the researchers found a way to add two electrons to every dopant molecule, effectively double doping the semiconductor and making it twice as effective. 

“The whole research field has been totally focused on studying materials which only allow one redox reaction per molecule,” said Christian Müller, an author of the study. “We chose to look at a different type of polymer, with lower ionisation energy. We saw that this material allowed the transfer of two electrons to the dopant molecule. It is actually very simple.” 

The findings were published in the journal <a href="https://www.nature.com/articles/s41563-018-0263-6">Nature Materials</a> and the results could help make organic electronics viable and competitive alternatives to inorganic semiconductors.

New research presents major breakthrough in organic electronics

Organic electronics have been quickly gaining traction in the world...

As <a href="https://www.earth.com/news/rates-loneliness-doubled/">we reported</a> last year, rates of loneliness have doubled over the past 50 years, despite the ability to connect online at almost any time. Since pharmaceutical solutions seem to be available for most other ailments, many have questioned if a pill could cure one of humanity’s greatest epidemics and hardest to treat afflictions.

This is the current goal of Dr. Stephanie Cacioppo, a neuroscientist who has studied loneliness for most of her career, and recently spoke to the <a href="https://www.dailymail.co.uk/health/article-6598703/A-pill-loneliness-Scientists-race-treat-condition-raise-premature-death-risks.html">Daily Mail</a> on her efforts to develop a loneliness cure.

With social media platforms and the internet connecting people all over the world in the blink of an eye, you would think loneliness would be a thing of the past. 

However, research has shown that people today feel more<a href="https://www.earth.com/news/loneliness-rise-united-states/"> isolated despite social media’s connectivity</a> and that pervasive loneliness impacts health and wellbeing, especially among younger generations. 

One 2018 nationwide survey of 20,000 US adults found that around <a href="https://www.npr.org/sections/health-shots/2018/05/01/606588504/americans-are-a-lonely-lot-and-young-people-bear-the-heaviest-burden">50 percent of the survey respondents felt lonely some or all of the time</a>. Studies have found links between loneliness and an increased risk of <a href="https://www.nytimes.com/2017/12/11/well/mind/how-loneliness-affects-our-health.html">diabetes, dementia, and cardiovascular disease</a>. 

Cacioppo recently had to deal with loneliness head-on after the sudden death of her husband, an event that motivated her to continue on with her research into what loneliness does to the brain and how to potentially treat it. 

A cure for loneliness may be closer than you think as Cacioppo found that pregnenolone (a steroid naturally made in the body) can help combat the anxiety that comes with feelings of loneliness. 

Several test studies and trials have shown that participants given pregnenolone have less activity in the amygdala and insula parts of the brain compared to control groups. These regions in the brain are linked to the flight or fight response and help people process and perceive threats around them. 

Cacioppo is in the process of analyzing data from a clinical trial in which 96 participants who reported feeling lonely were given different amounts of the steroid or a placebo. If the results are successful, Cacioppo and her team could soon develop a pill form of the steroid which could help ease the anxiety and negative symptoms of loneliness.

With loneliness on the rise, there may soon be a pill to treat it

As we reported last year, rates of loneliness have doubled...

Scientists at the <a href="https://en.wikipedia.org/wiki/European_Chemical_Society_(EuChemS)">European Chemical Society</a> (EuChemS) have created a new periodic table that highlights which elements are now considered endangered. Elements such as allium, arsenic, yttrium, and silver have become shockingly scarce and could vanish in less than 100 years at the current rate. 

The experts added a mobile phone symbol to the 31 elements that are used to make phones, hoping to send a powerful message about how much we depend upon these elements in our daily lives. The modified periodic table also distinguishes conflict minerals, which fuel violence and wars in the regions where they are extracted.

David Cole-Hamilton, a professor of Chemistry at the <a href="https://www.st-andrews.ac.uk/">University of St. Andrews</a>, pointed out that all of the conflict minerals are used in <a href="http://www.earth.com/news/smartphones-sleep-deprivation-kids/">cell phones</a>. 

“We have to question whether it’s really necessary to change over mobile phones every year or so. 10 million phones a month are changed in Europe alone. Most of them are sent to the developing world - either for reuse or for recycling - but the recycling is not efficient.”

[caption id="attachment_1865899" align="aligncenter" width="700"]<a href="https://www.earth.com/wp-content/uploads/2019/01/elements.png"><img class="wp-image-1865899" src="https://www.earth.com/wp-content/uploads/2019/01/elements.png" alt="" width="700" height="456" /></a> Image Credit: European Chemical Society[/caption]

Professor Cole-Hamilton also explained why we should be far more conservative with helium. He said that while it is widely used for magnetic resonance imaging and deep sea diving, the helium for both of these applications is recycled. 

“But if you have a helium balloon at a birthday party, it will either deflate or burst, and either way the helium is released into the atmosphere,” said Professor Cole-Hamilton. “Helium is so light that once it’s in the atmosphere it can actually escape from the Earth completely and go into outer space where it’s lost to us forever.”

The team hopes to make their periodic table accessible to everyone, and has already made “great progress in getting it into schools across Europe.” The Royal Society of Chemistry will be sending a copy to every one of its 50,000 members.

“It’s amazing to think that everything that we see around us in the natural world is made up from just 90 building blocks - the 90 naturally occurring elements,” said Professor Cole-Hamilton. “Furthermore, these 90 elements, in different combinations, make up all of the wonders of nature, and all the technology and gadgets we use every day. We need to have a better way of dealing with these resources, or we won’t have them anymore.”

The EuChemS version of the periodic table was launched this week at the European Parliament.

New discovery could pave the way for a plant-based. A genetically engineered microbe could be used to break down woody plant material and create a biodegradable alternative for plastic.

Finding environmentally friendly alternatives to plastic is a <a href="https://www.earth.com/news/protein-squid-alternative-plastics/">mission</a> taken on by a number of research teams, and the focus of these endeavors is typically the sugars and cellulose in plant cell walls. 

But while researchers have been able to break down plant materials and extract sugars, an abundant polymer called lignin is stripped away in the process. Lignin is so abundant and carries such little value that it’s typically just burned during manufacturing processes. 

If this lignin could be broken down and utilized efficiently, it could be used to make durable materials that could replace plastic. Unfortunately, the molecule is large, complex, and challenging to break down, and so it has been long overlooked until now. New discovery could pave the way for a plant-based plastic substitute 

Researchers from the <a href="https://www.wisc.edu/">University of Madison-Wisconsin</a> discovered that a microbe called Novosphingobium aromaticivorans efficiently digests the different components of lignin and produces smaller aromatic hydrocarbons in the process. 

A study detailing how the bacterium breaks down lignin and potential future implications for the microbe was published in the journal Green Chemistry. 

“Other microbes tried before may be able to digest a few types of aromatics found in lignin,” said Miguel Perez, the lead author of the study. “When we met this microbe, it was already good at degrading a wide range of compounds. That makes this microbe very promising.”

As Novosphingobium aromaticivorans digests lignin, it produces pyrone-4,6-dicarboxylic acid,  also known as PDC. The researchers found that by removing three genes from the microbe, they could expedite the PDC process. 

Bioengineers are already using PDC in Japan as a plastic replacement, but the difficult extraction process has kept lignin from being used over a wide scale. 

Now, the researchers say that the microbe could make PDC production at the industrial level a real possibility.

Extreme rainfall is defined as the top five percent of rainy days – which may mean different things to those who live in Seattle, Washington versus the Mojave Desert. But it has been known that <a href="http://www.earth.com/news/winter-rainfall-arctic-ecosystems/">extreme rainfall</a> forms a pattern at a local level. 

However, a new study published in <a href="https://www.nature.com/">Nature</a> has found that there are also larger-scale global patterns to extreme rainfall events, which could be used to develop better forecasts and more accurate climate models.

This research was led by a team at <a href="https://www.imperial.ac.uk/">Imperial College London</a> and the <a href="https://www.pik-potsdam.de/pik-frontpage">Potsdam Institute for Climate Impact Research</a> in Germany. Along with the potential of these findings to help improve global climate models, the study also provides a “baseline” for climate change studies. Through knowing how the atmosphere behaves to create patterns of extreme rainfall events, other researchers will be able to gain new insights into changes that may be a result of climate change.

“This finding could also help us understand the connections between different monsoon systems and extreme events within them,” says lead author Dr. Niklas Boers of the Potsdam Institute. “I hope that our results will, in the long term, help to predict extreme rainfall and associated flash floods and landslides in northeast Pakistan, north India and Nepal. There have been several such hazards in recent years, with devastating consequences in these regions, such as the 2010 Pakistan flood.”

In their research, the team developed a new method based in complex system theory in order to study high-resolution satellite data of rainfall. Through breaking the globe into a grid, they could see where events occurred and determine how “synchronous” they were. Their results revealed a potential mechanism for how the events were connected, as the patterns appeared to be created by Rossby waves, which are wiggles in fast-flowing currents of air way up in the atmosphere, known as jet streams. 

While Rossby waves have been linked to regular rainfall, this is the first study to connect them to extreme rainfall event patterns. 

“The new technique applied to satellite data shows very surprising relationships between extreme rainfall events in different regions around the world,” says co-author Brian Hoskins of Imperial College London. “For example, extreme events in the South Asian Summer Monsoon are, on average, linked to events in the East Asian, African, European and North American regions. Although rains in Europe do not cause the rain in Pakistan and India, they belong to the same atmospheric wave pattern, with the European rains being triggered first.”

The work done by these collaborative and multidisciplinary researchers could help shed light on how extreme weather events occur, and provide us with better forecasts and more accurate climate models.

If you’ve seen the movie Eternal Sunshine of the Spotless Mind, you may have wondered whether the “erasure” therapy seen in the film could potentially become a reality in the future. The plot revolves around two characters using this therapy to forget about their past relationship together. And according to real-life scientists, forgetting something can take more mental effort than trying to hold onto the <a href="http://www.earth.com/news/brains-work-backwards-memories/">memory</a>.

A new study published in <a href="http://www.jneurosci.org/">JNeurosci</a> has found that if we focus on negative experiences rather than suppressing them, we may be able to force unwanted memories from our brains. This research was done by Dr. Tracy Wang and colleagues at the <a href="https://www.utexas.edu/">University of Texas at Austin</a>, where they had young adults forget images of scenes and neutral faces by activating a brain area called the visual cortex.

The findings support a hypothesis that memories can be forgotten by activating them, which goes against popular belief. 

“We forget the majority of our experiences,” says Dr. Wang. “This may seem bleak, but memory loss is essential to the human experience; we are bombarded with too much information each moment to preserve everything.” 

Due to how much information we receive on a daily basis, forgetting is actually an adaptive feature of memory that allows us to discard unneeded or irrelevant information, so we can enhance our access to other memories. 

“'Which information should be saved and which discarded?” asks Wang. “While this challenge is often solved automatically by the brain, people can also exert volitional control over what they forget.”

The study shows new evidence that intentional forgetting involves enhancement of memory processing in the sensory cortex in order to achieve the desired forgetting of recent visual experiences. According to Wang, this enhancement temporarily increases the activation of memory representations, which makes it vulnerable to disruption. 

“Contrary to intuition, deliberate forgetting may involve more rather than less attention to unwanted information,” she explains. 

Although far from being developed into the erasure therapy from Eternal Sunshine of the Spotless Mind, this new research does have the potential to develop into a treatment where it could possibly benefit people who suffer from PTSD or other psychological conditions.

It doesn’t take a full-blown wine snob to know that older bottles tend to have higher price tags. But it’s not just the <a href="http://www.earth.com/news/red-wines-taste-dry/">wine</a> itself that may tie back to the past, as scientists have discovered that a grape variety still used in wine production in France can be traced back 900 years to just one ancestral plant.

Researchers have long suspected that some grape varieties grown today have an exact genetic match with plants grown 2,000 years ago or more, but there was never a way to genetically test an uninterrupted genetic lineage of that age. However, using an extensive genetic database of modern grapevines, scientists were able to analyze and compare 28 archeological seeds from French sites dating back to the Iron Age, Roman era, and medieval period. 

In a study published in <a href="https://www.nature.com/nplants/">Nature Plants</a>, the researchers used similar ancient DNA methods utilized in tracing human ancestors to draw genetic connections between seeds from different archaeological sites, along with links to modern-day grape varieties.

“From our sample of grape seeds we found 18 distinct genetic signatures, including one set of genetically identical seeds from two Roman sites separated by more than 600km, and dating back 2,000 years ago,” says Dr. Nathan Wales from the <a href="https://www.york.ac.uk/">University of York</a>. “These genetic links, which included a ‘sister’ relationship with varieties grown in the Alpine regions today, demonstrate winemakers’ proficiencies across history in managing their vineyards with modern techniques, such as asexual reproduction through taking plant cuttings.”

One of the grape seeds found at a medieval site in Orléans in central France was genetically identical to Savagnin Blanc (not to be confused with Sauvignon Blanc), which means the variety has grown for at least 900 years after beginning as cuttings from one ancestral plant. This grape is still grown in the Jura region of France and is used to make expensive bottles of Vin Jaune.

“We suspect the majority of these archaeological seeds come from domesticated berries that were potentially used for winemaking based on their strong genetic links to wine grapevines,” explains Dr. Jazmín Ramos-Madrigal, a postdoctoral researcher from the <a href="https://www.ku.dk/english/">University of Copenhagen</a>. “Berries from varieties used for wine are small, thick-skinned, full of seeds, and packed with sugar and other compounds such as acids, phenols, and aromas - great for making wine but not quite as good for eating straight from the vine.”

None of the Roman seeds excavated were found to have an identical genetic match with modern-day seeds, but the researchers did find two very close relationships with important grape families used in making high quality wine. Seeds were connected to the Syrah-Mondeuse Blanche family, with Syrah being one of the most planted grapes in the world today. Another connection was found with the Mondeuse Blanche, which is used to produce high quality AOC (protected regional product) wine in Savoy.

“It is rather unconventional to trace an uninterrupted genetic lineage for hundreds of years into the past,” says Dr. Wales. “Instead of exploring broad patterns in genetic ancestry, as in most ancient DNA projects, we had to think like forensics scientists and find a perfect match in the database.”

The researchers are now trying to find more archaeological evidence to further expand the history and knowledge of grape wine varieties. “Large databases of genetic data from modern crops and optimized palaeogenomic methods have vastly improved our ability to analyze the history of this and other important fruits,” Wales explains. “For the wine industry today, these results could shed new light on the value of some grape varieties; even if we don’t see them in popular use in wines today, they were once highly valued by past wine lovers and so are perhaps worth a closer look.”

<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.



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

<h2 class="wp-block-heading" id="h-scientists-discover-the-brain-s-tickling-command-center">Scientists discover the brain's 'tickling command center'</h2>



Researchers have finally solved one of humanity's most enduring mysteries: why we can't <a href="https://www.earth.com/news/after-centuries-of-debate-we-still-dont-know-how-tickling-works/" target="_blank" rel="noreferrer noopener">tickle</a> ourselves and what makes some people incredibly ticklish while others barely react? Recent scientific discoveries are revolutionizing our understanding of this peculiar human behavior.



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



In 2023, Dr. Michael Brecht's team at <a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Humboldt University</a>-<a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Berlin</a> made a major discovery published in the <a href="https://www.cell.com/iscience/fulltext/S2589-0042(22)01991-5" target="_blank" rel="noreferrer noopener">journal Neuron</a>. They identified the brain's actual "tickling command center" – specific neurons in a region called the periaqueductal gray that control both tickling responses and play behavior.



When researchers used cutting-edge optogenetic technology to shut down these neurons in laboratory rats, something remarkable happened. The animals completely lost their ability to be tickled or engage in playful behavior.



"We found that global blockade of the rat periaqueductal gray with either muscimol or lidocaine interfered with ticklishness and play," the research team reported in their study.



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



What we call "tickling" is two completely different phenomena, according to the latest research. Light tickling – that feathery sensation that makes you want to scratch – is essentially your body's sophisticated bug detection system. This alerts you to potential insects or parasites on your skin.



Deep tickling – the kind that makes you laugh uncontrollably – involves complex brain circuits and is fundamentally social. You literally cannot tickle yourself with this type of stimulation.



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



Your cerebellum acts like a prediction machine, recent findings show. When you move your own hand to touch yourself, your brain generates precise predictions about what you will feel and then cancels out the tickling sensation through neural inhibition.



When someone else tickles you, your brain can't predict their movements, so the full tickling response activates. It's like your brain's way of distinguishing between self and others.



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



Individual differences in ticklishness depend on genetics, psychology, and even trust. Dr. Xinzhong Dong at <a href="https://www.jhu.edu/" target="_blank" rel="noreferrer noopener">Johns Hopkins University</a> notes that people with denser nerve endings tend to be more sensitive.



Psychological factors matter just as much. You respond more strongly when tickled by people you trust, and anxiety completely shuts down tickling responses. This explains why the same physical stimulus can produce completely different reactions depending on who's doing the tickling.



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



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



Dr. Konstantina Kilteni's 2025 research, published in <a href="https://www.science.org/doi/10.1126/sciadv.adt0350" target="_blank" rel="noreferrer noopener">Science Advances</a>, reveals another technique: place your hand on the tickler's hand. This allows your brain to partially predict the sensations, reducing the tickling response by up to 90 percent.



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



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



From an evolutionary perspective, tickling serves vital functions according to <a href="https://www.umd.edu" target="_blank" rel="noreferrer noopener">University of Maryland</a> researcher Dr. Robert Provine's extensive studies. It trains our defense reflexes for vulnerable body areas and facilitates social bonding between family members.



Tickling-induced laughter is actually one of the first forms of communication between infants and caregivers. "Tickle involves a neurological self/nonself discrimination, providing the most primitive social scenario," Provine noted in his research.



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



Research shows people with autism spectrum disorder perceive touches as more ticklish than people without the condition. Investigating this difference could provide insight into brain differences and help advance autism research.



People with schizophrenia tend to experience self-touches similarly to external tickles, allowing them to essentially tickle themselves. This suggests altered sensory prediction mechanisms in the condition.



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



Scientists have discovered that many species beyond humans are ticklish. Rats emit ultrasonic "laughs" when tickled, while chimpanzees, gorillas, and orangutans all respond to tickling stimulation.



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



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



Dr. Kilteni argues that tickling research deserves more scientific attention. "It is a complex interplay of motor, social, neurological, developmental, and evolutionary aspects," she stated in her recent review.



New haptic technologies and advanced research methodologies now permit scientists to investigate tickle sensation with unprecedented precision. Standardized experimental methods using mechanical tickling devices ensure consistent results across studies.



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

</div><figcaption class="wp-element-caption">Dr. Ronald Mallett from the University of Connecticut reveals secret mission to create working time travel device.</figcaption></figure>



<h2 class="wp-block-heading" id="h-could-an-equation-truly-bend-time-a-physicist-s-decades-long-quest-to-rewrite-reality">Could an equation truly bend time? A physicist's decades-long quest to rewrite reality</h2>



Imagine the impossible: stepping back through time in a time machine, not in fantasy, but through a scientific endeavor driven by profound personal loss. For <a href="https://www.earth.com/news/astrophysicist-says-hes-cracked-the-equation-for-time-travel/" target="_blank" rel="noreferrer noopener">Dr. Ronald Mallett</a>, a distinguished astrophysicist and professor emeritus at the <a href="https://uconn.edu/">University of Connecticut</a>, this deeply human longing has fueled a lifelong mission. He claims to have discovered the equation that could unlock temporal displacement, pushing boundaries once deemed purely science fiction.



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



Mallett's extraordinary pursuit began with devastating tragedy in 1955. At merely 10 years old, he endured his father Boyd's sudden death—a television repairman whose passion for science had ignited a similar spark in his young son. Boyd Mallett, only 33, succumbed to a heart attack, leaving behind a grief-stricken child searching for solace.



That solace came through H.G. Wells' The Time Machine. Within its pages, Mallett found a captivating concept: "Time is only a kind of Space." These words transformed from a literary phrase into a guiding principle, becoming the driving force behind his unwavering commitment to unraveling time's fundamental mysteries.



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



Mallett's journey was far from straightforward. After serving in the Air Force during the Vietnam War era, he utilized the GI Bill for higher education, earning his Ph.D. in physics from Pennsylvania State University in 1973 at the age of 28.



In 1975, he made history as the first African American professor in the University of Connecticut's physics department, achieving full professorship in 1987 before retiring in 2024 as professor emeritus.



Throughout these successful academic years, Mallett harbored his radical ambition as a closely guarded secret. "I kept my time travel goal a secret," he confessed. "I worried people would think I was nuts." His public research centered on black holes, serving as a "cover story" while he quietly developed his revolutionary time travel theory.



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



His pivotal insight arrived while hospitalized for a heart condition—a profound irony given his father's heart attack started this journey. The breakthrough was elegantly simple yet revolutionary: "If gravity can bend time, and light can create gravity, then light can bend time."



"It turns out that black holes can create a gravitational field that could lead to the creation of time loops that could allow us to go back in time," he explained.



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



Mallett's vision for a functioning time machine replicates spacetime-warping phenomena around black holes. He offers a compelling analogy: "Picture a cup of coffee. Stir it with a spoon, and the coffee swirls. A spinning black hole does the same to spacetime."



In Einstein's general relativity, the universe is a dynamic fabric woven from space and time. Massive objects like black holes warp this fabric—an effect we perceive as gravity. Mallett theorizes that an intense, continuous, circulating beam of light from a ring of powerful lasers could replicate this gravitational torsion, effectively twisting time into a loop.



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



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



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



Mallett's research has gained worldwide media attention, featured on <a href="https://www.thisamericanlife.org/" target="_blank" rel="noreferrer noopener">National Public Radio's This American Life</a>, the <a href="https://www.history.com/" target="_blank" rel="noreferrer noopener">History Channel</a>, and <a href="https://www.today.com/" target="_blank" rel="noreferrer noopener">NBC's Today Show</a>. The widespread interest reflects both his compelling personal story and rigorous scientific approach.



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



While Mallett's equations captivate imagination, the path to reality faces immense obstacles. The energy requirement is staggering—Mallett acknowledges needing "galactic amounts of energy," far beyond current technological capabilities.



There's also a poignant limitation: even if realized, his machine could only send information back to when it was first activated, meaning it couldn't transport him to 1955 to prevent his father's death.



The scientific community remains skeptical. Physicists Ken Olum and Allen Everett argue that Mallett's proposed laser ring would need to be larger than the observable universe to achieve the necessary spacetime distortion. They invoke Stephen Hawking's chronology protection conjecture, suggesting physics may prevent macroscopic time travel.



Astrophysicist Paul Sutter has voiced doubts about Mallett's underlying mathematics, while science writer Brian Clegg finds the concept intriguing enough to warrant experimental investigation.



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



Now approaching 80, Dr. Mallett remains steadfast. "I believe my work will show time travel is possible," he asserts. "Future generations will build on it in ways we can't yet imagine."



His equations, though yet to physically bend time, have bent our collective imagination. Ongoing public interest, evidenced by his continued media appearances and Spike Lee's film adaptation of his memoir, underscores his ideas' profound impact.



More than a scientific pursuit, Mallett's story testifies to human resilience, intellectual courage, and hope's enduring power. Whether his theoretical time machine ever materializes, his legacy is immeasurable—inspiring countless individuals to challenge conventional limits and perceive time not as an unyielding barrier, but as a boundless frontier awaiting exploration.

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

</div></figure>



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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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

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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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