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 . ...

Antarctica's Hektoria Glacier stunned scientists by retreating eight kilometers in just two months, with nearly half of it collapsing in record time. The rapid breakup was driven by a flat, underwater bedrock surface that allowed the glacier to ...

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 .. ...

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, ...

A lost cache of 250-million-year-old fossils from Australia has rewritten part of the story of life after Earth's worst mass extinction. Instead of a single marine amphibian species, researchers uncovered evidence of a surprisingly diverse community ...

Horses have a vocal trick no one fully understood until now. Scientists have discovered that when a horse whinnies, it produces two completely different sounds at the same time. One is a deep tone created by vibrating the vocal folds, similar to how ...
