Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is unusually good at assembling into tiny liquid-like droplets that concentrate molecules and can harden into protective, gel-like structures. Remarkably, much of this behavior may come down to a single oxygen-containing chemical group that RNA has but DNA lacks.

Scientists discover a human brain gene that can jump through DNA

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans

Scientists just found a new way to make hydrogen from water

A new light-activated material can efficiently produce hydrogen from water without requiring an additional expensive metal catalyst. Researchers say its unusual sulfur-based chemistry could point toward cheaper and more practical ways to turn sunlight into clean fuel.

Scientists may have found a “unifying theory” of chronic fatigue

Scientists found that five seemingly unrelated conditions, including long Covid, ME/CFS, and PTSD, may disrupt many of the same biological networks involved in immunity, metabolism, and cellular energy. The findings could help explain their shared symptoms and may open the door t
