Ultimate self-sacrifice: Bacteria activate unusual defense to evade viral attack
For billions of years, viruses and bacteria have been embroiled in an arms race. In response to constant attacks by viruses known as bacteriophages—more commonly called "phages"—bacteria evolve new ways to defend themselves. And, in turn, phages evolve new strategies to overcome those defenses.
