Enigmatic viruses –not living, yet not dead–help create, protect and transform the universe, observed Carl Zimmer in his classic A Planet of Viruses. Viruses, he notes, have had a huge impact on the history of all life on Earth–their population of Earth’s Oceans would stretch out into space 42 million light years.
