Scientists at Stanford University and the Arc Institute created AI-generated viral genomes that produced 16 viable bacteria-infecting viruses, according to a study published in Science on August 6, 2026. A mixture of the viruses overcame antibacterial resistance in some E. coli strains—a promising experimental result that also prompted calls for stronger governance of biological AI. Key takeaways Evo designed genomes for viruses targeting specific bacterial hosts. Laboratory tests yielded 16 viable viruses from about 300 designs. The resulting bacteriophages infect bacteria, not humans. Johns Hopkins specialists called for safeguards around biological AI models.
