The Download: AI movie soundtracks, and DeepMind's disease prediction tool

The news: Google DeepMind says it's trained an artificial intelligence system that can predict which DNA variations in our genomes are likely to cause disease--predictions that could speed diagnosis of rare disorders and possibly yield clues for drug development. The background: Back in 2021, DeepMind announced that its program AlphaFold was able to accurately predict the shape of proteins, a problem considered a "grand challenge" in biology. Now the company says it has fine-tuned that protein model to predict which misspellings found in human DNA are safe to ignore and which are likely to cause disease. Why it matters: Although not intended to directly make diagnoses, computer predictions are already used by doctors to help locate the genetic causes of mysterious syndromes. But critics say the real test of modern artificial intelligence is whether it can lead to new cures, something that still hasn't happened.
