DeepMind AI handles protein folding, which humbled previous software

Proteins rapidly form complicated structures which had proven difficult to predict.

Today, DeepMind announced that it had seemingly solved one of biology’s outstanding problems: how the string of amino acids in a protein folds up into a three-dimensional shape that enables their complex functions. It’s a computational challenge that has resisted the efforts of many very smart biologists for decades, despite the application of supercomputer-level hardware for these calculations. DeepMind instead trained its system using 128 specialized processors for a couple of weeks; it now returns potential structures within a couple of days.

The limitations of the system aren’t yet clear—DeepMind says it’s currently planning on a peer-reviewed paper and has only made a blog post and some press releases available. But the system clearly performs better than anything that’s come before it, after having more than doubled the performance of the best system in just four years.
