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 ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then synchronizes them later using computation. This ...

Crystals hidden in Australia's oldest rocks have revealed new clues about how Earth and the Moon formed. The study suggests Earth's continents didn't begin growing until hundreds of millions of years after the planet itself formed. When scientists .. ...

Although the gut renews itself constantly, its stem cells accumulate age-related molecular changes that quietly alter how genes are switched on and off. Scientists found that this "epigenetic drift" follows a clear pattern and appears in both aging . ...

Sleep isn't just about feeling rested--it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or ...

New research shows that aging blood can accelerate Alzheimer's-like changes in the brain, while younger blood may offer protection. In mouse experiments, older blood worsened memory performance and increased toxic protein buildup linked to the ...

Pancreatic cancer is notoriously hard to treat, often resisting therapies that target its most common mutations. Researchers have now uncovered a hidden three-part loop that fuels tumor growth, involving the cancer drivers SRSF1, AURKA, and MYC. By . ...
