More dinosaur bones are found to contain residues of blood and soft tissue. The discovery could help point to when dinosaurs turned into warm-blooded creatures.

These spiders can purr
This wolf spider can purr like no other. It makes vibrations and sounds to tell a female he’s interested in her.

This endangered species gives new meaning to ‘single mom’
Scientists have found DNA evidence that in the wild, sawfish have produced offspring without mating. That’s a first for an animal with a backbone.

Biowarfare saves bats from killer fungus
Good news for bats. Those infected with white-nose syndrome may be cured by a brief exposure to fumes from therapeutic bacteria.

Scientists Say: Autopsy and Necropsy
Sometimes when animals die, they need to be investigated. These examinations have two special names. One is for people, the other for non-human animals.

This is no cold fish!
The opah is the fish closest to the whole-body warm-bloodedness typical of mammals and birds. This trait may give the species an edge in the ocean’s cold depths.

Scientists feed bed bugs (on purpose)
To study bed bugs in the lab, scientists had to first learn how to keep the blood-thirsty critters well fed. And that proved easier said than done.
