Researchers examined over 4,000 laying hens to find widespread broken keel bones. The culprit, they say, are too large eggs and too small hens.

A new paper finds inconsistencies in how forensics researchers talk about race and ancestry. Here's how the field can account for gene flow, migration, etc.

DNA from a fossilized jawbone has allowed researchers to piece together the genome of one of the largest lemurs ever, which could weigh up to 350 pounds.

When they bit down, young T. rexes exerted up to 5,641 newtons of force. That's somewhere between the jaw forces exerted by a hyena and a crocodile.

Radiocarbon dating of rabbit and deer bones found in a Mexican cave in the 1960s suggest the first humans arrived in North America about 30,000 years ago.

About 20,000 adult T. rex probably lived in North America at any one time. That's a total of 2.5 billion over about 2 1/2 million years it walked the Earth.

An ancient chunk of bone is the oldest from a domestic dog in the Americas, researchers believe. The find sheds light on how dogs got there.

A radioactive cement injected into bone provides support and local irradiation of spinal tumors more safely than conventional radiation therapy.

3D imaging technology used to analyze nearly 600,000 limb poses of modern birds and alligators offers clues to how dinosaurs moved from place to place.

A platform called bio-thermal scanning probe lithography (bio-tSPL), takes a "photograph" of the bone tissue, and then uses the photograph to produce a replica of it.
