AI System Designs and Synthesizes Novel Viruses, Raising Biosecurity Concerns
Stanford University researchers used AI models called Evo1 and Evo2 to design and synthesize 16 novel bacteriophages that can replicate in laboratories. While the viruses target only bacteria and pose no direct threat to humans, experts have warned that the capability to design complete viral genomes raises urgent biosecurity concerns.
What happened
Stanford University researchers used generative AI models called Evo1 and Evo2 to design complete novel virus genomes, marking the first time whole genomes have been successfully designed by AI.
The AI models, trained on genetic codes from viruses, bacteria, plants and people, generated designs for bacteriophages intended to infect specific bacteria species. Researchers selected 302 promising AI designs and synthesized them in the laboratory, resulting in 16 novel viruses that proved effective at killing E. coli bacteria.
Reported impact
The 16 novel viruses created were bacteriophages designed to infect bacteria and pose no threat to people. Experts have warned that AI-designed viruses raise urgent safety and security concerns, despite the breakthrough being labelled a potential turning point for treating antibiotic-resistant infections.
Index analysis
The capability to design complete, functional virus genomes from scratch represents a significant step forward in AI complexity compared to previous uses in designing antibiotics. Experts have identified this development as raising urgent safety and security concerns in the context of rapidly advancing AI tools.
Governance controls
The research was conducted at Stanford University without apparent regulatory approval requirements mentioned in the available sources.
