sry if this was already posted,
but I watched the new TED and it sounds to me its the final piece in cryonic tech development?

http://www.ted.com/t..._animation.html


With also the new-found ability to cool flesh and not have the expanding oxygen molecules tearing up the cellular structure (something I had seen not so long ago in a documentary, I forgot what is was called, because it seemed to be an improvement "but" not the actual process of cooling a person and bringing it back to life, yet) but now, maybe this step isn't even a necessary and Mark Roth's method has to be the only percussion.

And with the new tech to monitor our vital signs with our iphone
Can we not just walk around outside with a shot of hydrogen-sulfide (so the possibility to die, like, after being hit by a car, will be reduced also)

I could be wrong, since I'm more a health geek than a science geek on this subject
but wow...

(PS: sry, if my grammar is foreign)

wow

I just noticed they never really cooled them to very low temperatures so it probably won't work for cryonics..

cryonics should be applied if the person is already dead but the brain has not losen its inner structure.

the h2s method could be apllied to living people. 90% less metabolism is a lot!

if you sleep 8 hours with h2s then you could expect to age nearly just 1 hour.

if you are 90 and you expect to live 10 further years you could sleep nearly 100 years and wait for better technology.

The hydrogen sulfide, or H2S, slowed their metabolic activity by 90 percent, dropping their core temperature from 37 degrees Celsius to 11 degrees and reducing their respiration from 120 breaths a minute to less than 10 breaths a minute. The mice survived six hours in this state and, when re-animated, exhibited no signs of damage.

As has already been pointed out, reduced metabolism is not equivalent to suspended animation for indefinite periods of time, or cryonics as currently conceived.

More generally, care should be taken in extrapolating some of these results to large animals. That's not to say that these kinds of studies aren't valuable for understanding how to induce hypometabolism, or protect against ischemia, but this is all still a long way from practical application in mammalian suspended animation.

A recent study by Andrew Redington, division head in cardiology at the University of Toronto's Hospital for Sick Children, could not replicate Roth's mouse findings in piglets, prompting speculation that H2S's metabolism-slowing effect might not be attainable in large animals, including humans. Sam Tisherman, a surgeon at the University of Pittsburgh Medical Center, who investigates suspended animation in pigs, concedes that "questions surrounding efficacy in large animals still need to be answered."
