Artificial intelligence is being used in the field of biology to discover new drugs. A team of scientists at Stanford University has developed AlphaFold, an AI system that can predict the 3D structure of proteins. The structure of proteins is closely linked to their function and understanding it is vital in drug development. AlphaFold was tested against several protein structures and its predictions were found to be accurate. This breakthrough could potentially speed up the discovery of new drugs and revolutionize the field of medicine.
