Mark Roth
via Danger Room
It used to be that suspended animation was only for people heading to Planet LV-426, and former Red Sox players. But Mark Roth, a researcher at Fred Hutchinson Cancer Research Center in Seattle, Washington, thinks that short-term suspended animation can be used to help stabilize trauma patients on their way to the hospital. In his new TED talk, Roth explains how his technique differs from the cliche of freezing people until science finds a cure for their disease, and how it might drastically increase survival rates both on the battlefield and at home.
Roth's technique replaces inhaled oxygen with hydrogen sulfide. Normally toxic, hydrogen sulfide has the curious ability to alter the mammalian metabolism when applied in a cold environment. Using this technique, Roth has already managed to place lab animals into suspended animation, and safely bring them back. When in a suspended state, the body can better cope with the deadly oxygen deprivation that results from shock, massive blood loss, and heart attacks.
But don't take my word for it. Check out this TED video where Roth explains for himself how he came to this insight, the biology and history behind his technique, and the promise it holds for emergency medicine.

How cold are we talking? Enough to cause the water in our bodies to expand and destroy the cells? How long can one be in suspended animation before permanent suspended animation?
And no, I didn't bother to watch the video.
Watch the video rpenri.
Amazing work they are doing. I wonder if a person subjected to this would have some or any sense of the passage of time. if not then this would possibly offer a way to make space travel, like a trip to mars for example, seem much shorter to the crew by doing regular de-animation/re-animation cycles at the safe time limit of the de-animation period.
Truly amazing... This could be huge for modern medicine. Im interested to find out how long a human can be de-animated before it is permanent, and if so would there be any cell damage... ie would the cell still age. I would think so. Do watch the video.
I wonder if this could be adapted as a replacement/alternative for max security prisons?
I remember reading about this previously. I would like to see if cancer cells are affected the same way. I had an idea if it didn't effect cancer, put the regular cells in suspended animation and the cancer cells continue, burning themselves out without the support of the body.
The fact that hydrogen sulfide binds to the same spot as oxygen makes me think it would work. The warburg hypothesis shows cancer cells use glycolysis even in the presence of oxygen. Hydrogen sulfide would presumably dim only the regular cells, the cancer cells would keep running in overdrive but without the support of the rest of the body in providing nutrients, they will burn out and die.
I really hope someone tests this.
Lots of potential applications for this. Cancer treatment, space travel, emergency medical situations. I don't think using this on prisoners would be a good idea though. They should have time to think about the errors of their ways.

yes. though it is coming soon. I don't think it is necessary for us to get it. he explains how his technique differs from the cliche of freezing people until science finds a cure for their disease, But who knows. http://www.iphone-transfer-sms.com/.Good luck.
