Proteins are the molecular machinery of every living cell. Understanding their shape is essential to understanding how they function, and how drugs can interact with them. The protein folding problem had been unsolved for fifty years. Thousands of researchers across hundreds of labs had spent careers on it. AlphaFold solved it in months,...
