Cacti may look like slow, stubborn desert survivors, but they're actually evolving at lightning speed. Scientists studying more than 750 cactus species discovered that what really drives the explosion of new cactus species isn't flower size or ...

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 ...

Researchers created a special kind of algae that can grab microscopic plastic pollution out of water almost like a magnet. The algae produce limonene, an orange-scented oil that helps them bind to water-repelling microplastics, forming easy-to-remove ...

A bizarre new giant dinosaur discovered in Argentina is giving paleontologists a fresh look at how Jurassic titans evolved in the Southern Hemisphere. Bicharracosaurus dionidei stretched about 20 meters long and carried a strange mix of features seen ...
