A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported…

Scientists discover how colon cancer cells change identity to spread

Scientists have identified a molecular switch that may help explain how colorectal cancer becomes deadly. When levels of a gene-regulating factor called GATA6 drop, cancer cells can shed their normal…

Scientists discover why exercise reverses muscle aging

Researchers have uncovered a molecular “switch” that helps explain why exercise keeps ageing muscles healthy. By reducing levels of a gene called DEAF1, physical activity allows older muscles to clear…

Scientists discover the deep sleep circuit that builds muscle, burns fat, and boosts the brain

Researchers have identified the brain circuitry that links deep sleep with the release of growth hormone, revealing how the two regulate each other. The newly discovered feedback loop helps explain…
