    Scientists have found the first known microbes that can eat only viruses

    Lab experiments show that Halteria ciliates can chow down solely on viruses. Whether these “virovores” do the same in the wild is unclear.

    Here’s how mysterious last-resort antibiotics kill bacteria

    Scientists are finally getting a grip on how a class of last-resort antibiotics works — the drugs kill bacteria by crystallizing their membranes.

    How dormant bacteria spores sense when it’s time to come back to life

    Bacterial cells shut down and become spores to survive harsh environments. An internal countdown signals when it’s safe for bacteria to revive.
