Animals deep freeze for 30 years brought back to life
Japan's National Institute of Polar Research stored the 8 legged, segmented critters at -4F for just over 30 years. They thawed and revived two of the animals, which are also known as water bears or moss piglets, in early 2014.
One of them died 20 days into the experiment, reports the BBC. But its companion survived and managed to reproduce with a third tardigrade that had been hatched from a frozen egg. It went on to lay 19 eggs, of which 14 survived.
