Bacteria and the viruses that infect them, called phages, are locked in an evolutionary arms race. But that evolution follows a different trajectory when the battle takes place in microgravity, a study conducted aboard the International Space Station (ISS) reveals.
As bacteria and phages duke it out, bacteria evolve better defenses to survive while phages evolve new ways to penetrate those defenses. The new study, published Jan. 13 in the journal PLOS Biology, details how that skirmish unfolds in space and reveals insights that could help us design better drugs for antibiotic-resistant bacteria on Earth.
