Researchers from Stanford University and the Arc Institute have utilized genomic language models, specifically Evo 1 and Evo 2, to design entirely new, functional bacteriophages. Laboratory testing of 285 synthesized AI-designed genomes revealed that 16 successfully created functional viruses capable of infecting and destroying Escherichia coli bacteria.

Notably, these synthetic phages demonstrated the ability to target E. coli strains that had developed resistance to naturally occurring viruses. This development, published in the journal Science, offers potential therapeutic applications for phage therapy to combat antibiotic-resistant bacterial infections.

While the research team implemented safety measures to address the potential misuse of synthetic genetic code, the technology has triggered significant biosecurity concerns. Experts from the Johns Hopkins University Center for Health Security have warned that the ability to design viral genomes via AI raises pressing questions regarding biological safety and containment. Although researchers attempted to mitigate risks by avoiding training the AI on viruses capable of infecting humans or animals, experts have called for enhanced oversight and updated governance mechanisms to manage the security implications of AI-driven genetic design, noting that existing governance mechanisms do not yet exist to address these urgent questions.
