ISS experiments show microgravity alters bacteriophage–bacteria coevolution, with crew health and biosecurity implications
Experiments aboard the International Space Station found microgravity reshapes coevolution between bacteriophages and their bacterial hosts: phages remain infectious but evolve along different genetic pathways in near-weightlessness, sometimes toward traits associated with increased potency. Results carry direct implications for crew microbiome management and spacecraft biosecurity.
