Bacteria and the viruses that hunt them have learned to coexist — by keeping on the move

Phages are viruses that infect bacteria — nature's own antibacterial agents, and a hope for treating infections that resist antibiotics. A Georgia Tech study in Science Advances asked how bacteria and phages can live together instead of one wiping out the other. The answer, revealed by a model that tracks movement through space, is motion itself: bacteria that keep migrating can stay a step ahead, letting both sides persist. It is a small, elegant insight with practical stakes — designing phage treatments for stubborn infections on wounds or medical implants depends on exactly this dance.
