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.
Two unvaccinated residents in Pennsylvania have died from measles, triggering a public health debate. Governor Shapiro says vaccinations could have averted the deaths, while RFK Jr. questions the figures, fueling a political row that experts warn could hinder responses to the outbreak.
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.
