The Download: AI-designed viruses, and bad news for the hydrogen industry

Artificial intelligence can draw cat pictures and write emails. Now the same technology can compose a working genome.

A research team in California says it used AI to propose new genetic codes for viruses—and managed to get several of them to replicate and kill bacteria.

The work, described in a preprint paper, has the potential to create new treatments and accelerate research into artificially engineered cells. But experts believe it is also an “impressive first step” toward AI-designed life…
