‘The game has changed.’ AI triumphs at solving protein structures

sciencemag.org
  • DeepMind’s algorithm solves a 50-year old problem of predicting how proteins fold into 3D shapes that carry out life’s tasks.
  • Before, scientists solved the structures of only 170,000 out of 200 million proteins, but this algorithm is a game changer that will speed up this research insanely.
  • The algorithm was trained on the 170,000 solved proteins in an earlier version, but the new version has an added “attention algorithm” that really did the trick.
  • It works similarly to how we solve puzzles - first connects pieces in small chunks, and then searches for ways to join them together.
  • This opens up new avenues for science, could dramatically speed up the discovery of new medications, as well as development of enzymes for biofuels and recycling.
