Stanford researchers use AI to design functional synthetic viral genomes
Researchers from Stanford University and the Arc Institute have successfully used artificial intelligence to design entire viral genomes. Utilizing genome language models known as Evo 1 and Evo 2, the team trained the systems on massive datasets of natural DNA sequences to learn evolutionary patterns.
In laboratory tests, the researchers used the Phi X-174 bacteriophage as a template to generate thousands of novel designs. Out of approximately 300 chemically synthesized candidates, 16 emerged as fully viable, functional viruses capable of infecting and destroying E. coli bacteria. Notably, some of these AI-designed phages demonstrated the ability to overcome bacterial strains that had developed resistance to the original natural phage.
While this breakthrough offers significant potential for medical advancements, such as targeted gene therapies and new antimicrobial treatments to combat antibiotic resistance, it also raises substantial biosecurity concerns. Experts warn that the ability to design complete genomes could be misused to create dangerous pathogens or biological weapons. To address these risks, the research team focused exclusively on bacteriophages that infect bacteria and intentionally excluded genetic data from viruses that affect humans, animals, or plants.
