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, ...

Researchers say fructose is not just "empty calories" -- it may actively push the body toward fat storage and metabolic disease. A new review found that fructose affects the body differently from glucose, disrupting normal energy regulation and ...

A new international analysis suggests there may be a surprisingly simple secret to keeping weight off after dieting: walking about 8,500 steps a day. Researchers found that people who boosted their daily steps to around that level during a weight ...

A major new analysis suggests semaglutide (Ozempic, Wegovy) works remarkably well in adults over 65, helping many lose substantial amounts of weight while improving heart and metabolic health. Participants taking the drug lost over 15% of their body ...

A new study suggests AI chatbots may do more than spread misinformation -- they can actively strengthen a user's false beliefs. Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy ...
