Scientists at MIT have found compelling chemical evidence that Earth's earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old are rare molecular "fingerprints" that match compounds made by modern demosponges. ...

For decades, scientists believed a fertilized egg's DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already carefully arranged in three dimensions long before .. ...

Baby dinosaurs weren't coddled like lion cubs or elephant calves--they were more like prehistoric latchkey kids. New research suggests that young dinosaurs quickly struck out on their own, forming kid-only groups and surviving without much parental . ...

Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon's magnetic field -- and it turns out both sides were right. By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate ...

Biomolecular condensates were long believed to be simple liquid blobs inside cells. Researchers have now uncovered that some are actually supported by fine protein filaments forming an internal scaffold. When this structure is disrupted, cells fail . ...

The Old Irish Goat isn't just part of folklore -- it's genetically linked to goats that lived in Ireland 3,000 years ago. Scientists analyzed ancient remains and discovered that today's rare breed shares its strongest DNA ties with Late Bronze Age .. ...

"Forever chemicals" known as PFAS have quietly infiltrated everything from nonstick pans to food packaging--and now new research suggests some of them may be speeding up the aging process itself. In a nationally representative U.S. study, two lesser ...

Eating nothing but oatmeal for just two days might sound extreme, but it delivered a striking payoff in a new clinical trial. People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop . ...

Earth's magnetic shield is shifting in dramatic ways. New data from ESA's Swarm satellites show that the South Atlantic Anomaly -- a vast weak spot in Earth's magnetic field -- has grown by nearly half the size of continental Europe since 2014. Even ...

Mars' frozen ice caps may be time capsules for ancient life. Lab experiments show that key building blocks of proteins can survive tens of millions of years in pure ice, even under relentless cosmic radiation. Ice mixed with Martian-like soil, ...
