Aeronautic engineers say long-term cryogenic sleep could be the key to humans travelling long distances through space. A NASA-funded study has found spaceships would be able to cover much longer distances if they didn't have to support human activity, and the technology to make this possible could be available within the next three decades.

OVER the course of an average winter North American wood frogs, Rana sylvatica, may freeze solid several times. They are able to get away with this by replacing most of the water in their bodies with glucose mobilised from stores in their livers. That stops ice forming in their tissues as temperatures drop. When things warm up again, the frogsicles thaw out, with no evident ill effects.

Scientists revived tiny Siberian worms that had been frozen in permafrost for 42,000 years — and they started moving and eating
A group of Russian scientists have successfully revived two species of tiny worms that they discovered suspended in an icy chunk of Siberian permafrost. The worms, known as nematodes or more commonly as roundworms, had been frozen for up to 42,000 years, since a time when much of the planet was covered in ice. But they weren't dead - just cyrogenically preserved.
