A three-year study of nearly 4,000 adults ranging from age 19 to 94 found that brain health can improve at any age, challenging the common belief that mental sharpness must decline as we get older. Participants spent just a few minutes a day on brain-training activities, and researchers found measurable gains across multiple aspects of brain health, including thinking clarity, emotional well-being, and sense of purpose.

Keeping sex on the schedule may be its own menopause medicine: among 900 women aged 40-79, those active in the last three months reported far less dryness, pain, and irritation, while orgasm and overall satisfaction stayed rock-solid despite dips in desire and lubrication. The results hint that intimacy itself can curb genitourinary syndrome of menopause, a cluster of estrogen-related symptoms that erode quality of life. Read more ›

A blockbuster diabetes and weight-loss drug might be doing more than controlling blood sugar—it could also be protecting the brain. Researchers at Case Western Reserve University found that people with type 2 diabetes who took semaglutide (the active ingredient in Ozempic and Wegovy) had a significantly lower risk of developing dementia. The benefit was especially strong in women and older adults. Read more ›

Lichen from the Mojave Desert has stunned scientists by surviving months of lethal UVC radiation, suggesting life could exist on distant planets orbiting volatile stars. The secret? A microscopic “sunscreen” layer that protects their vital cells—even though Earth’s atmosphere already filters out such rays. Read more ›

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 ›

Southern resident killer whales have been caught on drone video crafting kelp tools to groom one another—an unprecedented behavior among marine mammals. This suggests a deeper social and cultural complexity in these endangered whales than scientists previously realized. 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 ›
