Phys.org / Hubble uncovers the secret of blue straggler stars that defy aging

Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...

Phys.org / Scientists may have discovered a new extinct form of life

Prototaxites are something of a prehistoric mystery. They were the first giant organisms on land, towering over ancient landscapes at heights of up to 8 meters. They had smooth trunk-like pillars and no branches, leaves or ...

Phys.org / Four-eyed Cambrian fish fossils hint at origins of vertebrate pineal complex

New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure found in multiple 518 million-year-old fossils, which appears ...

Phys.org / Amplifying feedbacks could drive Greenland ice sheet to near-complete disappearance

Greenland, which has been prominently in the news in recent days, hosts a vast ice sheet. If it melts, it will become one of the largest contributors to global sea-level rise. Under a high-emissions scenario, the Greenland ...
