A large genetic screen has revealed how stem cells transform into brain cells, exposing hundreds of genes that make this process possible. Among the discoveries is PEDS1, a gene now linked to a previously unknown neurodevelopmental disorder in ...

Roasted coffee may do more than wake you up--it could help control blood sugar. Researchers discovered several new coffee compounds that inhibit -glucosidase, a key enzyme linked to type 2 diabetes. Some of these molecules were even more potent than ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an extended version of Einstein's gravity, ...

KAIST researchers have developed a way to reprogram immune cells already inside tumors into cancer-killing machines. A drug injected directly into the tumor is absorbed by macrophages, prompting them to recognize and attack cancer cells while ...

In a striking real-world experiment, flu patients spent days indoors with healthy volunteers, but the virus never spread. Researchers found that limited coughing and well-mixed indoor air kept virus levels low, even with close contact. Age may have . ...

Scientists have used CRISPR to give the goldenberry a modern makeover, shrinking the plant by about a third and making it easier to farm. Goldenberries are tasty and nutritious but notoriously unruly, with bushy plants that complicate harvesting. By ...

A rapid climate collapse during the Late Ordovician Mass Extinction devastated ocean life and reshuffled Earth's ecosystems. In the aftermath, jawed vertebrates gained an unexpected edge by surviving in isolated marine refuges. Over millions of years ...

Scientists have discovered an enormous stream of super-hot gas erupting from a nearby galaxy, driven by a powerful black hole at its center. The jets stretch farther than the galaxy itself and spiral outward in a rare, never-before-seen pattern. NASA ...

Scientists have identified a brand-new species of worm living in the Great Salt Lake, marking only the third known animal group able to survive its extreme salinity. The species, named Diplolaimelloides woaabi with guidance from Indigenous elders, .. ...

A new international trial has delivered striking results for people on dialysis, showing that daily fish oil supplements can sharply reduce serious heart-related events. Patients taking fish oil had far fewer heart attacks, strokes, and cardiac ...
