Much of the recent AI hype train has centered around mesmerizing digital content generated from simple prompts, alongside concerns about its ability to decimate the workforce and make malicious propaganda much more convincing. (Fun!) However, some of AI’s most promising — and potentially much less ominous — work lies in medicine. A new update to Google’s AlphaFold software could lead to new disease research and treatment breakthroughs. AlphaFold software, from Google DeepMind and (the also Alphabet-owned) Isomorphic Labs, has already demonstrated that it can predict how proteins fold with shocking accuracy. It’s cataloged a staggering 200 million known proteins, and Google says millions of researchers have used previous versions to make discoveries in areas like malaria vaccines, cancer treatment and enzyme designs.  Knowing a protein’s shape and structure determines how it interacts with the human body, allowing scientists to create new drugs or improve existing ones. But the ne...
