Ancient human relative used fire, surprising discoveries suggest
Charcoal and burned bones offer intriguing — if controversial — clues that the species Homo naledi made hearths to light its way and cook in dark caves.
Death metal singers have a vocal counterpart ... in bats
Bats and death metal singers have more in common than a love of the dark. A new study has found that some of bats' lower frequency calls appear to use a technique similar to death metal growling.
