Ancient microbes from deep within the seafloor have been found to “revive and multiply” in the laboratory after laying dormant for more than 100 million years.

Scientists in the US and Japan have found that these deep-sea microorganisms were capable of growing and dividing, even after remaining in an energy-saving state since dinosaurs roamed the planet.
