Overview
- Stanford researchers used an AI model called Evo2 to generate 285 candidate bacteriophage genomes from scratch and screened them in petri-dish tests.
- Sixteen AI-designed viruses showed activity against E. coli, and a mixture of those 16 overcame highly resistant bacterial strains in laboratory assays.
- One minimal design, Evo-Φ2147, comprising 11 genes across about 5,386 base pairs, was synthesized and demonstrated bactericidal effects in vitro.
- Caltech scientists reported a DNA construction tool named Sidewinder in Nature that claims much higher accuracy for assembling long genetic sequences.
- Developers and advisers cite potential medical applications and say safeguards were used, including not training on human-pathogenic viruses, while urging clearer oversight.
