In new experiments of time perception, when pupils were large, monkeys underestimated a second.
- Paleontology
First known fossilized dinosaur brain unearthed, scientists claim
A dinosaur fossil that preserves brain tissue has been discovered for the first time, researchers announce.
- Paleontology
Picture of primate common ancestor coming into focus
A new family tree analysis predicts behavior of primate common ancestor.

Early birds could achieve liftoff
Early birds and other flying dinosaurs had the strong legs and wing speed needed to launch into the air directly from the ground, researchers argue.

How to make a fish face, and other photo contest winners
The tiny face of a 4-day-old zebrafish embryo snags the top spot in microscopy photography contest.
- Genetics
Ancient hookups gave chimps a smidge of bonobo DNA
Genetic evidence suggests bonobos and chimpanzees interbred after becoming separate species.
