Researchers at Stanford and the Arc Institute have used generative genome models to design and synthesise bacteriophage genomes; 16 of the lab-made viruses proved viable and a cocktail of them rapidly killed E. coli strains resistant to natural phages. Experts have warned the work has raised urgent biosafety and biosecurity questions about AI-designed genomes.
A Russian lab worker has died amid reports of pneumonic plague in Irkutsk. The case has prompted quarantines and widespread monitoring as officials assess risk to the general population. U.S. and international health authorities are watching closely while cautioning that immediate threats remain limited.
