Wildfires don’t just leave behind scorched earth—they leave a toxic legacy in Western rivers that can linger for nearly a decade. A sweeping new study analyzed over 100,000 water samples from more than 500 U.S. watersheds and revealed that contaminants like nitrogen, phosphorus, organic carbon, and sediment remain elevated for up to eight years after a blaze.

Major depressive disorder affects hundreds of millions worldwide, but a key to understanding its origins may lie in the brain’s immune system. New findings spotlight astrocytes—previously overshadowed by microglia—as major players in neuroinflammation that drives depression. These star-shaped brain cells, once thought to only support neurons, are now shown to regulate communication between brain cells and even trigger or amplify inflammatory responses. Read more ›

UC San Diego scientists have created a gene therapy that goes beyond masking Alzheimer’s symptoms—it may actually restore brain function. In mice, the treatment protected memory and altered diseased brain cells to behave more like healthy ones. Read more ›

Over 300 million years ago, Earth experienced powerful bursts of carbon dioxide from natural sources—like massive volcanic eruptions—that triggered dramatic drops in ocean oxygen levels. These ancient "carbon burps" led to dangerous periods of ocean anoxia, which stalled marine biodiversity and potentially reshaped entire ecosystems. In a groundbreaking study, scientists combined high-tech climate models with deep-ocean sediment analysis to pinpoint five such events. The alarming part? Today's human-driven. Read more ›

Scientists have uncovered a stealthy tactic used by the SARS-CoV-2 virus: one of its proteins can leap from infected cells to healthy ones, effectively tricking the immune system into attacking the body’s own tissues. Read more ›

Two Ice Age wolf pups once thought to be early dogs have been identified as wild wolves, thanks to detailed DNA and chemical analysis. Surprisingly, their last meals included woolly rhinoceros meat—an unusually large prey item—hinting that ancient wolves might have been bigger than today’s. Their well-preserved bodies also shed light on wolf pack behavior and Ice Age environments. Read more ›

Exploration for deep-sea minerals in the Clarion Clipperton Zone threatens to disrupt an unexpectedly rich ecosystem of whales and dolphins. New studies have detected endangered species in the area and warn that mining noise and sediment could devastate marine life that relies heavily on sound. With so little known about these habitats, experts urge immediate assessment of the risks. Read more ›

DNA from a skull found at Newgrange once sparked theories of a royal incestuous elite in ancient Ireland, but new research reveals no signs of such a hierarchy. Instead, evidence suggests a surprisingly egalitarian farming society that valued collective living and ritual. Read more ›

What if your old chest scans—taken years ago for something unrelated—held a secret warning about your heart? A new AI tool called AI-CAC, developed by Mass General Brigham and the VA, can now comb through routine CT scans to detect hidden signs of heart disease before symptoms strike. Read more ›

In a remarkable twist of science, researchers have transformed a fungus long associated with death into a potential weapon against cancer. Found in tombs like that of King Tut, Aspergillus flavus was once feared for its deadly spores. Now, scientists at Penn and several partner institutions have extracted a new class of molecules from it—called asperigimycins—that show powerful effects against leukemia cells. These compounds, part of a rare group known... Read more ›

Researchers in Sweden have developed a powerful new material that dramatically boosts the ability to create hydrogen fuel from water using sunlight, making the process eight times more effective than before. This breakthrough could be key to fueling heavy transport like ships and planes with clean, renewable energy. Read more ›

Despite widespread fears, early research suggests AI might actually be improving some aspects of work life. A major new study examining 20 years of worker data in Germany found no signs that AI exposure is hurting job satisfaction or mental health. In fact, there s evidence that it may be subtly improving physical health especially for workers without college degrees by reducing physically demanding tasks. However, researchers caution that it... Read more ›

Scientists at NIST and the University of Colorado Boulder have created CURBy, a cutting-edge quantum randomness beacon that draws on the intrinsic unpredictability of quantum entanglement to produce true random numbers. Unlike traditional methods, CURBy is traceable, transparent, and verifiable thanks to quantum physics and blockchain-like protocols. This breakthrough has real-world applications ranging from cybersecurity to public lotteries—and it’s open source, inviting the world to use and build upon it. Read more ›

Scientists at the University of Amsterdam discovered that our brains automatically understand how we can move through different environments—whether it's swimming in a lake or walking a path—without conscious thought. These "action possibilities," or affordances, light up specific brain regions independently of what’s visually present. In contrast, AI models like ChatGPT still struggle with these intuitive judgments, missing the physical context that humans naturally grasp. Read more ›

A simple blood test could reveal which early Alzheimer’s patients are most at risk for rapid decline. Researchers found that people with high insulin resistance—measured by the TyG index—were four times more likely to experience faster cognitive deterioration. The study highlights a major opportunity: a common lab value already available in hospitals could help guide personalized treatment strategies. This discovery also uncovers a unique vulnerability in Alzheimer’s disease to metabolic... Read more ›

Colistin, a last-resort antibiotic, is losing its power due to rising resistance—and the culprits might be hiding in your seafood dinner. A University of Georgia research team discovered colistin-resistance genes in bacteria found in imported shrimp and scallops from markets in Atlanta. These genes can hop between bacteria via plasmids, potentially turning once-curable infections into deadly threats. Read more ›

A Rice University team discovered that bubbling CO₂ through a mild acid dramatically improves the lifespan and efficiency of electrochemical devices that convert CO₂ into useful fuels. This simple trick prevents salt buildup—a major barrier to commercialization—by altering local chemistry just enough to keep salts dissolved and flowing. The result? A device that ran for over 4,500 hours without clogging, using common catalysts and scalable technology. It's a breakthrough that... Read more ›
