A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful ...

Researchers have uncovered unexpectedly high levels of silicone-based pollutants called methylsiloxanes floating through the atmosphere across cities, rural regions, and even forests. Much of the pollution appears to come from vehicle emissions, ...

The little pauses, "ums," and moments when you struggle to find the right word may reveal far more about your brain than anyone realized. Researchers discovered that everyday speech patterns are closely tied to executive function -- the mental system ...

Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule's unusual twisted structure, solving a ...

Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses--the group behind diseases like polio, myocarditis, encephalitis, and even the common cold--to reproduce inside human cells. The team ...

Researchers found a new way to kill harmful "zombie" cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a ...

As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body's ability to regenerate healthy blood and immune cells. By calming this cellular "overdrive," researchers restored the stem cells' ...

A four-week diet change was enough to make some older adults appear biologically younger in a new University of Sydney study. Participants who reduced fat intake or shifted toward more plant-based protein showed improvements in key health biomarkers ...

Scientists at McGill University have uncovered a hidden molecular "switch" that turns on a powerful calorie-burning system in brown fat -- the body's heat-generating fat linked to metabolism and weight control. The breakthrough centers on glycerol, a ...

Staying strong may be one of the biggest secrets to living longer -- especially for older women. A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, ...
