Natural Gas to Offer Breakthrough in Suspended Animation?

Kingcanute writes "The BBC is reporting that American scientists are claiming that sewer gas may be successful at inducing suspended animation. The results were achieved using mice but further studies are needed" From the article: "The problem with hypothermia is it's not that easy to cool down the human body so if we can find another method to inhibit metabolism that would be very useful"

Incomplete science

[BWJones]

So, this is pretty interesting, but this smells like (LOL, H2S.... get it?) incomplete science in that they appear to have gone to the press without first, doing the real experiments that would tell them more about what is going on here. Simply looking at core body temperature, heart rate and blood pressure will not tell you the status of organ function, nor will it tell you anything about potential organ system damage. Dr. Chris Pomfrett's letter is right on where he questions: "My big question about this work is: is it reducing brain metabolism or simply having a toxic effect on the brain stem?", but he only gets part of it right in his suggestion to perform an electroencephalogram (EEG) as well.

Additional tests can not simply be EEG combined with standard histology as you need to know something about how the tissues are responding in metabolic space, especially as how they are introducing a new small molecular species to the mix. EEG is only going to tell you the global overall status of the tissues, but it too will be altered in ways that may or may not be informative. I would suggest looking at early immediate gene expression profiles for apoptotic pathways and performing experiments designed to actually look at and document the metabolic profiles of these cells/tissues.

I am thinking specifically of some of the techniques we have developed (pictures of some tissues using these techniques can be seen here), but there are many, many other traditional biochemical and metabolic assays that could have been performed for these studies like HPLC, MassSPEC etc...etc....etc....

Re:The REAL problem with CRYOGENICS

[Swift Kick]

No sir, you're "incredibly stupid" by not reading the full article.

Had you bothered to read it instead of simply going by the short quote, you'd understand that the article has nothing to do with 'cryogenics'.
The quote is from a larger statement where they're referring to inducing hypothermia in patients undergoing cardiac surgery or with severe trauma, where it helped stabilize the metabolism of the victims, which resulted in better outcome on the treatment.
The article itself is aimed at medical uses such as the ones described above. This research has *nothing* to do with space travel, but is geared at preserving organ function in critically ill patients, where hypothermia is regularly induced to slow down organ deterioration.

Now go back to your cave.
