Researchers at Washington University, led by Professor Hong Chen, have advanced the concept of synthetic torpor, mimicking natural energy conservation seen in some mammals and birds. Their study, published in *Nature Metabolism*, reveals a groundbreaking technique to induce a reversible torpor-like state in mice and rats through focused ultrasound targeting the hypothalamus preoptic area, essential for body temperature and metabolism regulation. This innovative approach could have significant implications for medical therapies and space travel, offering new insights into metabolic control and energy conservation.
