Induction of a torpor-like state with ultrasound

Researchers induced a hibernation-like state in mice by using ultrasound to stimulate the hypothalamus preoptic area in the brain, which helps to regulate body temperature and metabolism. The findings show the first noninvasive and safe method to induce such a state; a similar condition has been previously proposed for spaceflight or for patients with life-threatening health conditions.
