Phys.org / Newly discovered viral enzymes act like molecular scissors to disable immune alarm signals

Viruses and their hosts—whether bacteria, animals, or humans—are locked in a constant evolutionary arms race. Cells evolve defenses against viral infection, viruses evolve ways around those defenses, and the cycle continues.
