Squirrel-cicle?
Frozen squirrels?
It sounds rather strange to me, but according to this article on Wired News, there’s a squirrel in the arctic that can lower it’s body tempurature to below freezing and still be able to walk around. Scientists are studying this incredible adaptation to see if they can synthesize it in humans. It would be a giant step toward all the cryogenic sleep chambers that science-fiction loves so well. Not to mention what it might do for real-world space travel!
In any case, it’s an interesting article and a fascinating concept.
