A bizarre class of molecules may play a role in disease: proteins that cluster together to form spherical droplets inside human cells.

The liver is the only organ that can regenerate, but it doesn't always work after surgery. New research sheds light on why.

The way proteins vibrate can help scientists identify them, which could lead to new medical tests or ways to evaluate drugs.

"The WNT pathway is different in stem cells and differentiated cells," research finds. That comes as a surprise.

Researchers have devised a faster, more efficient way to design custom peptides and perturb protein-protein interactions.

See how the barriers that protect our organs from disease-causing invaders get fixed when cracks form.

A method highlights forms of proteins that likely play a role in several neurodegenerative diseases including Alzheimer's and Parkinson's.

When older cells' fuel tanks start to get low, they have trouble performing their functions. A new discovery could change that.
