Animals spend a lot of energy avoiding toxic chemicals in their food. A new type of gene that does this in fruit flies reinforces the importance of reproduction in shaping evolution.

A new study finds a surprising number of fish, birds and mammals in the oceans 100 and 1,000 years ago. Can this information help regulators slow the decline of important marine animals?

We explore the sad saga of pet primates. Are these pets psychologically good for us? For them? Are humans and other primates trading diseases at home, and in the wild?

You can’t hold your eyes completely still, but what is the purpose of those tiny movements? A new study could explain why we make them — and why we seldom notice them.

The theory of evolution is 150 years old, but forever young. We examine proofs for evolution, and four cool studies showing just how correct Charles Darwin was. Want to talk about silent crickets?

Locusts live a solitary life — until their bodies suddenly change, and they swarm into clouds of destructive insects. A new study fingers the trigger for this transformation.

Three giant new reserves, extend 50 miles out from shore, will protect coral reefs, fish, clams, and other life forms. But how effective are marine protected areas?

Specialization may work in factories, but it does not make ant colonies more efficient. As the conventional wisdom about social insects goes topsy-turvy, what’s an ecologist to think?

The color, vision and genetics of an African fish all vary depending on the clarity of its home waters. A new study suggests how species can form without geographic barriers.

Lenses cannot project a perfect image on the flat back of a camera, so images are distorted at the edges. A revolutionary camera solves this problem by curving the light detector.
