Folding Proteins For Fun And Profit
A new computer game, called Foldit, turns protein folding into a competitive sport for anyone with a computer. Its creators say Foldit capitalizes on people's natural 3-D problem-solving skills and they hope to get a significant fraction of the world's population working on solving critical health problems...
