Space-born phages gain edge against Earth bacteria

Scientists studied bacteria and their viruses aboard the International Space Station and found that microgravity drives phages to evolve in ways that boost their ability to infect bacteria. When space-adapted phages were returned to Earth, they showed increased activity against common, drug-resistant E. coli strains, suggesting space-driven mutations could help optimize phage therapies for infections on Earth, though the practical costs of space-based research remain a consideration.
