AI makes huge progress predicting how proteins fold – one of biology's greatest challenges – promising rapid drug development

A simple chain of amino acids folds into a complex three-dimensional structure.TakeawaysSolving what biologists call “the protein-folding problem” is a big deal. Proteins are the workhorses of cells and are present in all living organisms. They are made up of long chains of amino acids and are vital for the structure of cells and communication between them as well as regulating all of the chemistry in the body.This week, the Google-owned artificial intelligence company DeepMind demonstrated a deep-learning program called AlphaFold2, which experts are calling a breakthrough toward solving the g…
