Learn about the Science

Proteins help fight disease by first assembling themselves or "folding." When proteins misfold, there can be serious health consequences.

If we better understand protein misfolding we can design drugs and therapies to combat these illnesses. ... Learn more.

Learn about the Software

Folding@home software aids research by simulating protein folding. The calculations are immense so we break them into small "work units" and pass them to individual computers like yours to solve.

Stanford computers assemble data from thousands of work units into meaningful answers to important scientific questions. ... Learn more.
