Research Summary


Our goal is the clinical application of active hypometabolism. We aim to provide effective and meaningful treatment for issues in modern medicine that stem from a high basal metabolic rate of human or human tissues. We believe synthetic hibernation for human can drastically improve medical transportation, tissue preservation, and the safety of general anesthesia. Moreover, if human lifespan can be safely extended by synthetic hibernation, traveling to the future or to deep space would not be a fiction anymore. The spaciotemporal cognitive function of human will change totally. Toward human hibernation, we will especially focus on discovering the mechanism of natural hibernation and torpor.
