Reactions: hibernation-like state induced in rats and mice by ultrasound
By directing ultrasound to a specific area of the brain, scientists at the University of Washington have succeeded in inducing a state very similar to hibernation in rats and mice. This state, called "torpor", involves a reduction in metabolism and body temperature to save energy. According to the authors, who publish their results in the journal Nature Metabolism, if it could be applied to humans it could be used in space travel or in medicine, to increase the chances of survival in life-threatening situations such as heart attacks or strokes.
