Sponges may be ancient, but their timeline has been murky. New research suggests the earliest sponges were soft and skeleton-free, explaining why their fossils don't appear until much later. By analyzing hundreds of genes and modeling how skeletons . ...

Scientists have uncovered a surprising new way that giant embryonic cells divide--without relying on the classic "purse-string" ring long thought essential for splitting a cell in two. Studying zebrafish embryos, researchers found that instead of ...

Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building . ...

Scientists racing to tackle plastic pollution have created a surprising new contender: a biodegradable packaging film made partly from milk protein. Researchers at Flinders University blended calcium caseinate with starch and natural nanoclay to form ...

Scientists at UC Berkeley have discovered a microbe that bends one of biology's most sacred rules. Instead of treating a specific three-letter DNA code as a clear "stop" signal, this methane-producing archaeon sometimes reads it as a green light- ...

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 . ...
