The bacteriophage's day just went from "inject and conquer" to "screaming in viral agony."

Twenty years of teaching microbiology and I still find it hilarious how these bacteria evolved their own tiny bouncers that just say "nope, your DNA isn't on the guest list." Nature's most elegant rejection letter.
