A massive whale graveyard in the Indian Ocean contains the remains of hundreds of extinct whales dating back more than five million years, along with recent carcasses that support hotspots of seafloor life.

Researchers report a "serendipitous" discovery while watching videos of crowds: an inexplicable bias toward counterclockwise turning that may be rooted in biology.

The north-south albedo symmetry may be fading as both hemispheres get darker.

A random sequence in an innocuous GPS message field is likely encrypted traffic from the U.S. military's system for remotely updating cryptographic keys around the world.

A new study suggests that bacteria dispersed through space on dust grains could potentially arrive intact and alive on Jupiter’s moon Europa.

Whalers buried in the Norwegian Arctic in the 1600s and 1700s are thawing out of the permafrost, underscoring the threat of climate change to archaeological sites around the world.
