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.

After injury, the visual system can recover by growing new neural connections rather than replacing lost cells. Researchers found that surviving eye cells formed extra branches that restored communication with the brain. These new pathways worked much like the originals. The repair process, however, was slower or incomplete in females, pointing to important biological differences in recovery. Read more ›

New research reveals when glaciers around the world will vanish and why every fraction of a degree of warming could decide their fate. Read more ›

Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike crater-forming impacts, these events unleash extreme heat and pressure without leaving obvious scars, making them harder to detect. Read more ›

Gravitational waves from black holes may soon reveal where dark matter is hiding. A new model shows how dark matter surrounding massive black holes leaves detectable fingerprints in the waves recorded by future space observatories. Read more ›

Astronomers have detected spacetime itself being dragged and twisted by a spinning black hole for the first time. The discovery, seen during a star’s violent destruction, confirms a prediction made over 100 years ago and reveals new clues about how black holes spin and launch jets. Read more ›

Much of the western U.S. is overdue for wildfire, with decades of suppression allowing fuel to build up across millions of hectares. Researchers estimate that 74% of the region is in a fire deficit, meaning far more land needs to burn to restore healthy forest conditions. Catching up would require an unprecedented amount of controlled and managed fire. Read more ›

Researchers have uncovered that the body uses different molecular systems to sense cold in the skin versus internal organs. This explains why surface chills feel very different from cold experienced deep inside the body. Read more ›

Firefighter turnout gear is designed to shield first responders from extreme heat and danger, but new research suggests it may also introduce chemical exposures. A U.S. study found that brominated flame retardants are present across multiple layers of firefighter gear, including newer equipment marketed as PFAS-free. In some cases, these chemicals appeared at higher levels than the substances they were meant to replace. Read more ›

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some cancers and how it could be improved for others. Read more ›

After a decade of painstaking measurements, scientists have delivered a major plot twist in particle physics: a long-hypothesized “mystery particle” likely doesn’t exist. Using the MicroBooNE experiment at Fermilab, researchers analyzed neutrinos from two powerful beams and found no evidence for a sterile neutrino, ruling it out with 95% certainty. Read more ›

Traces of opium found inside an ancient alabaster vase suggest drug use was common in ancient Egypt, not rare or accidental. The discovery raises the possibility that King Tut’s famous jars once held opiates valued enough to be buried with pharaohs—and stolen by tomb raiders. Read more ›

More than 20% of young adults say they use cannabis or alcohol to fall asleep, with cannabis leading by a wide margin. Researchers warn this strategy can backfire, disrupting sleep quality and increasing the risk of long-term sleep and substance-use problems. Read more ›

AI tools designed to diagnose cancer from tissue samples are quietly learning more than just disease patterns. New research shows these systems can infer patient demographics from pathology slides, leading to biased results for certain groups. The bias stems from how the models are trained and the data they see, not just from missing samples. Researchers also demonstrated a way to significantly reduce these disparities. Read more ›

Researchers have identified a previously overlooked protein that helps regulate appetite and energy use in the body. This “helper” protein supports a key system that decides whether the body burns energy or stores it, and when it does not function properly, appetite signals can weaken. Read more ›

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more powerful, affordable, and practical. Read more ›

A long-standing physics mystery has been solved with the discovery of emergent photon-like behavior inside a strange quantum material. The finding confirms a true 3D quantum spin liquid and unlocks a new way to study deeply entangled matter. Read more ›

A missing brain molecule may be disrupting neural wiring in Down syndrome, according to new research. Replacing it in adult mice rewired brain circuits and improved brain flexibility, challenging the idea that treatment must happen before birth. Read more ›

California researchers are preparing for the possible return of the New World screwworm, a parasitic fly that feeds on living flesh and once devastated U.S. livestock. By monitoring traps and educating veterinarians and farmers, they hope to stop the pest before it gains a foothold. Read more ›

A rare tick-borne allergy linked to red meat has now been confirmed as deadly for the first time. A healthy New Jersey man collapsed and died hours after eating beef, with later testing revealing a severe allergic reaction tied to alpha-gal, a sugar spread by Lone Star tick bites. Symptoms often appear hours later, making the condition easy to miss. Researchers warn that growing tick populations could put more people... Read more ›

Kimchi may do far more than add flavor to meals—it could help fine-tune the human immune system. A clinical study using advanced single-cell genetic analysis found that regular kimchi consumption strengthens immune defenses while preventing harmful overreactions. Researchers observed improved activity in key immune cells, with effects varying depending on fermentation methods. Read more ›
