Placing Astronauts in suspended animation has been proposed as one way for an individual to reach the end of an interplanetary or interstellar journey, avoiding the necessity for a gigantic Generation Ship ; occasionally the two concepts have been combined, with generations of "caretakers" supervising a large population of frozen passengers. --Three of the Discovery One crew are in a state of hibernation, ostensibly to conserve resources for the voyage.]] Since the 1970's Hypothermia has been induced for some Open-heart Surgeries as an alternative to Heart-lung Machine s. Hypothermia though only provides a limited amount of time to operate and there has been some evidence of risk of tissue and brain damage. An article in the April 22, 2005 issue of the scientific journal ''Science,'' reports success towards inducing suspended animation in Mice . The findings are significant, as mice do not hibernate in nature. The breakthrough was achieved when the lab of Mark Roth placed mice in a chamber containing 80 Ppm Hydrogen Sulfide , and the test was conducted for 6 hours. The mice's core body temperature dropped to 13 degrees Celsius and Metabolism , as assayed by Carbon Dioxide production and Oxygen use, decreased 10-fold. In July 2005 scientists at the University of Pittsburgh's Safar Center for Resuscitation Research announced they had managed to bring dogs back to life with no brain damage by draining the blood out of the dog's bodies and putting an ice cold solution into their circulatory systems, which in turn keeps the bodies alive in stasis. After 3 hours of being clinically dead, the dogs were revived by an electric shock to their hearts. The heart started pumping the blood around the frozen body, and the dogs were brought back to life. Scientists hope to begin human testing in 6 months and have already begun discussions with hospitals to use "suspended animation" if everything else fails. Safar Research also pioneered modern CPR techniques. While most of the dogs were fine, a few of the revived dogs had severe nervous and movement coordination damage, causing them to be mentally disabled, and demonstrating behavior that was deemed " Zombie " like. This has been pushed further by the media which named them "Zombie Dogs" . There is concern that this technique, if used on humans could result in brain damage similar to those suffered by some of the dogs in the experiment. Safar Research believes that the process is merely another way to give "more time" to the operation table, as vital repairs could be made when patients are in stasis: emergency operations fail frequently simply because the lack of time, not the lack of expertise. On January 20, 2006, an article published in The Sydney Morning Herald claimed pigs had been placed in suspended animation, and revived with a 90 percent success rate. SUSPENDED ANIMATION IN FICTION Suspended animation is also a common device in fiction used to transport individuals from one time period to another, often by accident, to wait for a cure, or to offer a kind of immortality. Among the characters or works that utilize suspended animation are:
