A bacterium that sat dormant in a frozen pond in Alaska for 32,000 years has been revived by NASA scientists. Once scientists thawed the ice, the previously undiscovered bacteria started swimming around on the microscope slide.
The researchers say it is the first new species of microbe found alive in ancient ice. Now named Carnobacterium pleistocenium, it is thought to have lived in the Pleistocene epoch, a time when woolly mammoths still roamed the Earth. The find bolsters the case for finding life elsewhere particularly as frozen lakes have been found just beneath the surface of Mars.
