AI Turns Its Artistry to Creating New Human Proteins

Using many of the same techniques that underpin DALL-E and other art generators, these scientists are generating blueprints for new proteins -- tiny biological mechanisms that can change the way of our bodies behave. From a report: Our bodies naturally produce about 20,000 proteins, which handle everything from digesting food to moving oxygen through the bloodstream. Now, researchers are working to create proteins that are not found in nature, hoping to improve our ability to fight disease and do things that our bodies cannot on their own. David Baker, the director of the Institute for Protein Design at the University of Washington, has been working to build artisanal proteins for more than 30 years. By 2017, he and his team had shown this was possible. But they did not anticipate how the rise of new A.I. technologies would suddenly accelerate this work, shrinking the time needed to generate new blueprints from years down to weeks. "What we need are new proteins that can solve modern-day problems, like cancer and viral pandemics," Dr. Baker said. "We can't wait for evolution." He added, "Now, we can design these proteins much faster, and with much higher success rates, and create much more sophisticated molecules that can help solve these problems." Last year, Dr. Baker and his fellow researchers published a pair of papers in the journal Science describing how various A.I. techniques could accelerate protein design. But these papers have already been eclipsed by a newer one that draws on the techniques that drive tools like DALL-E, showing how new proteins can be generated from scratch much like digital photos. "One of the most powerful things about this technology is that, like DALL-E, it does what you tell it to do," said Nate Bennett, one of the researchers working in the University of Washington lab. "From a single prompt, it can generate an endless number of designs."
