Rana Sylvatica is an unassuming wood frog with an extraordinary gift. In the depths of winter, it can slow down its metabolism, flood its cells with ice and remain in a state of suspended animation for months. But it's what it might be able to teach us about preserving human organs for transplant that has scientists really excited. Also, the menagerie in an icy test tube — San Diego's Frozen Zoo and the fight to preserve biodiversity.
