    A couple years ago Inhuman Experiment did a run down of cases of humans hibernation, from Russian peasants to trapped skiers:

    During the same TED Talk, he mentions experiments showing that if you reduce the oxygen content in the air slightly, roundworms die, and if you reduce it a lot – down to 10 ppm – they stop moving and appear dead but are in fact alive in a state of suspended animation. Unlike their animated and lively friends, these suspended roundworms can be put into cold temperatures without harm.

    Exposing an organism to hydrogen sulfide is another way to achieve the same effect as reducing the oxygen content of a container or a room. By binding at the same cell site as oxygen, hydrogen sulfide reduces the need for oxygen, depressing metabolism. Roth theorizes that perhaps hydrogen sulfide production was increased in Bågenholm’s own body when she fell under the ice, thus preventing her from dying from the cold.

    The first practical application of this technique is surgery, which requires mild hypothermia to prevent harming patients. Even with a small amount of injectable hydrogen sulfide, which Roth’s company has developed, the results are apparently better than with a traditional approach. Safety studies are already done, and human trials are underway.

    While this is undoubtedly a great medical breakthrough, I can’t help but think of other possible applications. What Roth has done is deanimate a mouse by reducing its metabolism and then bring it back to life unharmed. If the human trials are succesful, could this mean hydrogen sulfide might be used even outside surgery? Are we talking about a potential lightweight version of cryonics?
