A newly discovered vesicle is the first identified in 20 years and the smallest known, say researchers. And it acts like a bike courier.

An antibody that gunks up the machinery that flu viruses use to replicate in mice could be the first step towards a universal flu vaccine.

Mapping the proteins secreted by brown and white fat reveals their different roles throughout the body.

A cerebral hemorrhage can cause brain damage even after a patient survives, but new research indicates a way to stop it.

Low levels of a protein called TOM-1 may be behind inflammation in Alzheimer's disease, but fixing the problem could be a new way to fight the condition.

A common protein in nano-bio labs is prone to pushing gold nanorods into right-handed chiral assemblies—while producing chiral plasmonic signals to match.

An abundance of the ApoE protein, also associated with Alzheimer's and heart disease, may explain why older people have more trouble healing broken bones.

Creating a mutation in a key protein could stop the Ebola virus from evading immune defenses and making its hosts sick, researchers say.

Proteomics, a new forensics tool, means "reading DNA when you don't have any DNA to read." Here's how the technique works.

A new method is letting researchers get at the ancient proteins preserved in a rhino tooth fossil from almost 2 million years ago.
