Science
Sewer Gas May Allow For Suspended Animation
Posted by Adam Frucci at 8:30 AM on March 26, 2008
Suspended animation — the state that space travelers are always put into in movies so they don't age while travelling for many years — may turn out to actually be possible, and it's a simpler process than you'd expect. Yep, all you need to fall into a deep sleep and not age is a good dose of sewer gas.
Scientists have discovered that small doses of Hydrogen sulfide put mice into a completely reversible state of metabolic suppression. Within minutes of inhalation of the gas the mice began to show the effects and were able to stap out of it within 30 minutes of the air supply being returned to normal.
If this can be done to humans, it could be used to "allow organ function to be preserved when oxygen supply is limited, such as after a traumatic injury" as well as, you know, for long-term space travel. Bring on the sewer-gas-induced comas! [Eurekalert via io9]

I was reading an article about this via the Economist recently...
I believe they were saying that H2S could have some good implications for victims of heart attacks. My recollection might be wrong, but I think they were alluding to paramedics being equipped with the stuff to keep you alive during transport. You could probably find it on economist.com, let me know your results.

I think they forgot to mention the side effects, like death!(A guy my friend worked with died 2 weeks ago from it)
Hydrogen sulfide can affect several different systems in the body. Exposure to lower concentrations can cause eye irritation, a sore throat and cough, shortness of breath and fluid in the lungs. These symptoms usually go away in a few weeks after exposure ends. Long-term, low- level exposure may result in fatigue, loss of appetite, headaches, irritability, poor memory and dizziness. Breathing very high levels of hydrogen sulfide can cause death within just a few breaths. There could be loss of consciousness after one or more breaths.

You could sleep for 500 hundred years, but you'd have to smell your own gas the whole time. And wake up smelling like ass.
To paraphrase Dave Atell, you could use some lemon scented spray. But you just end up with a lemony-ass smell. And nothing beats ass.

Ah. That completely reverses my causal perception of retirement homes. I thought that as people aged, they passed more gas. Turns out, they are living longer because they pass more gas.
Beans, beans the life-extending fruit
The more you eat, the more you toot
The more you toot, the longer you live
So mash me up some beans and feed me through a sieve.

A completely reversible state of metabolic suppression?
What kind of suppression are we talking about? I mean, personally I think sniffing sewer gas would definitely shut off my appetite, which probably slows down my metabolism, but I'm having trouble believing it's anything close to a situation where I could stay asleep for a year.
I think it would be impossible to suspend animation completely. You would still have to stick all sorts of tubes and needles into the astronauts to feed them and antibiotics, so that they don't die of infection from bed sores, etc. Then, how do you cope with the massive muscle loss that comes with not moving for a year? You'd have to shock their muscles with electrical impulses to slow down deterioration, and how do you shock them without kicking them back out of the coma?
I might eat less and use less oxygen for a year, but I'd be in such worse shape than if I was just awake on the spacecraft.

Maybe the mice are just pretending they did not do it?...

i wonder what the upper limit on this state is though? i mean are we talking a few days? months? years? centuries?
makes a pretty big difference concerning usefulness.

and from another study: "Conclusions: H2S does not appear to have hypometabolic effects in ambiently cooled large mammals and conversely appears to act as a hemodynamic and metabolic stimulant." -[tinyurl.com]
yay for studies!

@jetexas: why would muscles that are metabolizing at 1% their normal rate reduce in size? If you're in a coma your body is still running at near 100% metabolism.
Why would there be bed sores in the absence of gravity?

I find it funny that the article says, "Hydrogen sulfide is the stinky gas that can kill workers who encounter it in sewers." Anyone who's done any work in the refining or natural gas industries should know a lot about it. After doing plenty of work in these environments for the past few years, I think I'll pass...
H2S is nasty stuff... You start smelling it at a concentration 1ppm. The maximum allowable exposure level is 10ppm. @ 20ppm you get irritation of eye, nose and throat areas. At 50ppm, you lose your sense of smell (and therefore your main indicator that you're exposed to H2S), get a headache and dizziness. 100ppm is IDLH (immediately dangerous to life and health). At 500ppm, unconsciousness occurs within a few minutes, followed by respiratory paralysis. If not rescued by someone with SCBA gear within 3-15 minutes, you die.
I recently visited an oil field in west Texas where there was a big sign in the operators' building that said, "H2S: THIS GAS WILL KILL YOUR ASS"

@Jason: unless there's another study getting ready to break wide open the whole warp drive thingy, then we'd still be traveling under full acceleration 1/2 ways, then *flip* and full deceleration the other 1/2 way. Soooooo, replace gravity with g-force and bed sores still a factor! now, with metabolism running at 1%, would bedsores be less likely? I think so, but that remains to be proven.
