In a milestone that bridges the gap between medical innovation and biosecurity risks, scientists have successfully created the first viruses designed entirely by artificial intelligence. These are bacteriophages—viruses that exclusively target bacteria—which, in laboratory tests, proved capable of neutralizing E. coli strains resistant to natural phages.
The Technology Behind 'Genomic AI'
Dr. Brian Hie of Stanford University utilized the Evo1 and Evo2 models, which function as "genomic language models." Trained on data from 2 million bacteriophages, these models generated thousands of potential genomes. Out of these, 300 were synthesized in the lab, and 16 were found to be viable and functional.
To mitigate risks, researchers intentionally excluded genetic code from viruses that infect humans, plants, or animals from the training data. Nevertheless, the success of the project demonstrates that AI can now synthesize functional viral genomes from scratch.
Warnings Over the Governance Gap
Despite the hope for transforming phage therapy, the scientific community is raising urgent alarms. Professor Tom Inglesby of Johns Hopkins University emphasized that while the technology to synthesize genomes is now a reality, the necessary governance to guide its safe use is non-existent.
"Such genomes may encode new pathogens that... cannot be contained with existing countermeasures,"experts warned in the journal Science.
Conversely, Professor Tom Ellis of Imperial College London offered a more tempered view, noting that designing a virus from scratch remains an immense challenge. According to Ellis, the more immediate threat lies in modifying existing pathogens rather than the full AI-driven synthesis of new ones.
