A 2,000-year-old Herculaneum scroll buried by the eruption of Mount Vesuvius is filled with lost words that scholars can now decipher thanks to AI and a particle accelerator.

The North Pole was above freezing on Sunday after an extreme winter warming event caused temperatures to climb more than 36 F (20 C) in the high Arctic.

Santorini's earthquakes are intensifying as a rare earthquake swarm continues to rattle the Mediterranean's Aegean Sea. The earthquakes are probably caused by faults rather than volcanic activity.

Researchers unveiled a super-strong nanoscale material made from the first two-dimensional mechanically interlocked polymers. The material resembles medieval chainmail at the molecular level and could be used in body armor.

A little penguin colony in Australia struggles during years with high penguin divorce rates, but the divorcees could have more offspring in the long run if they find better mates, a new study finds.

The first pterosaurs had a sail-like tensioning system for flying with potentially cumbersome tail vanes, which they could have used for displays, a new study finds.
