Colorectal cancer is increasingly showing up in younger adults, with cases now appearing in people as young as their thirties -- often with no family history or warning signs. A major Swiss study analyzing nearly 100,000 cases over four decades found ...

A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based "epigenetic clocks," with the . ...

Scientists analyzing the genomes of thousands of people across Japan discovered evidence for a previously overlooked third ancestral group, challenging the long-accepted "dual origins" theory. The newly identified ancestry appears linked to the ...

UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause ...

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 ...
