A missing protein in the brain can cause behaviors that mimic autism, a new study shows.

A protein called Sestrin can mimic the benefits of exercise, research with flies on treadmills shows. The finding could help people with muscle wasting.

The synthesized "bilingual molecule" could become a powerful tool for diagnostics, gene therapy, and drug delivery that targets specific cells.

Until now, nobody has been able to take a close look at the condensin and cohesin proteins that wrangle DNA into shape.

New research could help boost production of proteins for medical applications, food, agriculture, and other industries.

Adenoviruses need one protein to unpack their DNA to infect human cells and without it, the infection fails. The finding could lead to new antivirals.

Protein levels in a drop of blood can accurately predict someone's age, researchers say. The discovery sheds new light on how we age differently.

With more targeted drug delivery, doctors might not have to give patients larger doses of a drug to treat a specific part of the body.

Our immune systems can fight off a huge range of viral invaders, but HIV can avoid a protein that specializes in hunting viruses. New research explains how.

Researchers have reconstructed the evolutionary relationship between a 2 million year old extinct primate and today's living orangutan.
