An international team of biologists recently reported on the supposed evolution of sound production in perch-like fishes. Researchers know that some fish cause their swimbladders to vibrate by using unique superfast muscles that produce, for example, courtship calls. How did these special muscles originate?

A recent study found that about one in five scientists who say they are atheists or agnostics actually attend church or some other religious institution, and the main reason may be because of their children.

Biologists recently found that feather colors and songs vary among some species within the South American genus Sporophila, also known as seedeater birds. But strangely, they did not find any genetic differences in the form of species-specific DNA markers. Do these variations fit any evolutionary pattern?

Workers expanding a highway in 2010 found fossils of 80 huge whales in desert sandstones in Chile, prompting questions of how they died and why they were so well preserved.

Harvard's Wyss Institute specializes in designing new materials and devices that mimic patterns found in living things. Their latest contribution was inspired by the versatile material found in insect cuticle, which is strong and flexible, yet remarkably lightweight.
