"Ultrasound Stimulation Induces Hibernation-Like State for Long-Term Space Travel"

Scientists at Washington University in St. Louis have developed a noninvasive method to induce a torpor-like state in mammals using ultrasound stimulation of the brain. The technique involves stimulating the hypothalamus preoptic area in the brain, which regulates body temperature and metabolism, and was shown to effectively reduce body temperature and metabolic rate in mice, leading to a state of torpor. The method could potentially be used in scenarios like space flights or for patients with severe health conditions to conserve energy and heat.
