How Viruses Secretly Control the Planet
(Inside Science) — Viruses control their hosts like puppets — and in the process, they may play important roles in Earth’s climate.
The hosts in this case aren’t people or animals: They are bacteria. A growing body of research is revealing how viruses manipulate what bacteria eat and how they guide the chemical reactions that sustain life. When those changes happen to a lot of bacteria, the cumulative effects could potentially shape the composition and behavior of Earth’s oceans, soil and air.
