Discoveries, innovations, and the big ideas reshaping our understanding of the world.
Stanley Prusiner's claim that a protein alone could be infectious almost ended his career. Today prions are recognized as the agents behind a family of fatal neurological diseases, and their mechanism is reshaping how we understand Alzheimer's, Parkinson's, and more.

After an amputation, most patients continue to feel the missing limb — sometimes vividly, sometimes painfully. Phantom limbs are not psychological tricks.
