DARPA is now trying to do this in real life. DARPA wants to mimick the biological and chemical processes of water bears and wood frogs who are able to place themselves into a biological suspended state.
When a Service member suffers a traumatic injury or acute infection, the time from event to first medical treatment is usually the single most significant factor in determining the outcome between saving a life or not. First responders must act as quickly as possible, first to ensure a patient's sheer survival and then to prevent permanent disability. The Department of Defense refers to this critical, initial window of time as the "golden hour," but in many cases the opportunity to successfully intervene may extend much less than sixty minutes, which is why the military invests so heavily in moving casualties as rapidly as possible from the battlefield to suitable medical facilities. However, due to the realities of combat, there are often hard limits to the availability of rapid medical transport and care.
DARPA created the Biostasis program to develop new possibilities for extending the golden hour, not by improving logistics or battlefield care, but by going after time itself, at least how the body manages it. Biostasis will attempt to directly address the need for additional time in continuously operating biological systems faced with catastrophic, life-threatening events.
