Human Hibernation on the Horizon? 511 writes "The BBC is reporting that scientists at University of Washington have successfully induced a state of extreme hibernation in mice. The mice suffered no ill effects. Naturally, testing in larger animals will ensue. Humans wouldn't necessarily appreciate the smell of hydrogen sulfide while being placed into suspended animation. However, the applications are numerous if the usage of similar techniques can be applied to us. Cancer treatment, delaying death from injuries, interplanetary expeditions top the lists of possibilities. While it's not a quick freeze, maybe Fry will be able to meet Bender after all."

      The uses are almost endless. Anyone can build a home H2S chamber and just shut themselves down for days at a time. I can envision a time when people are freed of the need to wait for anything. Spiderman 7 coming out in 15 days and you just can't wait? Hop in the chamber, dial it up for 14 days and 23 hours, and just "chill out".

      The cool thing is that since metabolic activity cease, your cells would stop dividing, and therefore the aging process would cease as well. Opportunistic viruses would not multiply since they require cellular mitosis, and most bacteria would also take a nap.

      I would, however, worry about anaerobic bacteria, especially the kind that thrive on sulfur gases; they'd literally eat you for lunch while you were out like a light. If even one of those suckers got inside, then when someone opened your chamber six months from now you'd be pretty much a skeleton with a mass of oozing, smelly residues--ewwwww!

      I would also wonder about undigested food sitting in your stomach and small intestine for days or months, not to mention feces still in the colon. You want to move that stuff through before you shut down the system. On second thought I think I'll wait before trying this one out.

      It will drop you for a little more than "momentarily". H2S has the capacity to kill at less than 100ppm, depending on how long your exposure is. Yes, it will make you pass out -- but you might never wake up.

      It's nasty stuff and all refineries, pipelines, and other oil/gas installations are trained about H2S and it's risks. Where H2S is present in the lines, you will see many of the technicians wearing portable H2S monitors.

          Here's another little nerdy fact about H2S. It's very easy to detect. H2S reacts with Lead Acetate to produce a brownish lead sulfide. So, you create a roll of lead acetate tape and then "spot" your samples onto it. If H2S is present, it will create a brownish lead sulfide which is easily visible.

          The best part about it is this: H2S is the ONLY substance that reacts with lead acetate in this way. So interference and false signals are a non-issue. Brown = H2S. White = no H2S.

    I'm up for a little hibernation for space travel, but for medical aid? Aren't we already saving too many people who should be dead and thereby contributing greatly to world problems like overcrowding and world hunger and fun stuff?
    • The solution to world problems like overcrowding and world hunger is not to let disease and ill health cut population down to size. That is simply barbaric in this day and age. As humanity progress, I believe we should seek social solutions for social problems rather than let nature prune our civilization as if we were a herd of hoofed herbavores. Otherwise, the whole lot of slashdot readers would have become extinct through vicious sexual selection preasures.
      • Our options really are to cut down the population or to increase the area we live in (unless we /want/ to live with 300 people per square nanometer). So, either let people die or explore space and colonize other planets and/or moons. I'm just pointing out which one we're more capable of.
        • Um you must not travel much. Contrary to popular belief the world is NOT overpopulated. Infact I am sure it could handle 10 or 20 billion. Extreme poverty and man made disasters are the real causes of so much misery present in the world today.

          As hibernation tech increases you can bet many will pay millions for it, and why not? All we need now is some megacorp to set up a freezing station on the moon to store all those human popsicles and they will be billionaires.

        • Or, we stop reproducing so much. It's really not that hard, and what's even better is that wealth appears to result in people having fewer children -- so as standards of living improve, population growth will slow. Europe already has negative population growth once you subtract out imigration, and the US is on its way.
        • by Anonymous Coward on Friday April 22, 2005 @05:34AM (#12311361)
          If you do a little math, you'll see that neither killing people nor exploring space are solutions to overpopulation.

          The population is just growing too quickly. We get 75 million new people a year.

          Let's start with the easy one -- space colonies. You can start exploring planets all you want, but unless you can figure out a way to ship off more than 75 million people a year, the population is still going to increase on Earth. Think about how many resources and man-hours are required to get seven people into LEO -- we couldn't reduce population by shipping people into space even if the whole world were united behind the project.

          Next, let's talk war. Suppose you started a war that lasted a week and killed 1,000,000 people. That's a lot of people in a short amount of time -- it would be horrific. At the end of that week, you'd still have 430,000 more people than you started with! You could drag that war on for ten years, kill half a billion people (more than any war in history), and you'd still be way behind. Sure, you could pull out the nukes, but then you'd be reducing livable space and making a mess for the survivors.

          The other thing you have to keep in mind is that many of the people saved by modern medicine are already past child bearing. The sort of people who could afford hiberation treatment would be in wealthy countries where the birth rate is low, anyway.

          Everyone dies eventually, so killing a few adults off early doesn't change much in the long term balance sheet. The only practical way to do so is to alter the birth rate.

          And one of the best ways to lower birth rates is to raise living standards and give people access to modern medical care (including contraceptives). When the mortality rate drops to some reasonable level and half the family isn't sick from malaria, you don't need to overproduce children just to make sure you'll have enough healthy members in the family.

          It's also a lot more efficient for people to have a few healthy children than it is for them to spend resources raising a lot children only to have some large portion of them struck down by one of the four horsemen.

            I agree, although for different reasons. Concraception is not the reason that most postindustrial countries have low birth rates. For the most part, it is just more economically efficent to have many children in poor countries and less efficent to have children at all in wealthy countries.

            If you live on a subsistence level, every child is another pair or hands to work the farm, or help out however. In the US, Europe, etc, a child is a drain on your resources for 18+ years. So you have fewer.

            We do need to give access to concraceptives to deal with overpoplation, but if we just raise the standard of living, contraceptives, and economical pressure to use them, will follow.

              Sorry it just isn't that simple. If it were then why did the U.S. birthrate PLUMET when the pill was introduced?

              Having studied birthrates and the third world I can tell you what some studies have said.

              First of all most Women is poor countries DON'T HAVE FARMS. These isn't little house of the prairie where a bunch of little helpers go out and milk the cows. They live in poverty with very little to provide sustenance. These women have children by the bushels for numerous reasons, but one of the most striking is a concept called numeracy. They don't have it. It is the concept of how many children one has, e.g. only child, 2, 3 then stopping. When you ask a woman is sub-saharran Africa how many children she wants she will reply with something like - "as many as god gives me" or "I don't know what you mean, as many as will come".

              What most studies find about lowering birthrates in the thirdworld is an insanely simple answer: empower women. When women become empowered they begin to feel they can control their environment and by extension their reproduction.

      No, the problems of world overcrowding and hunger are not problems of supply, they're problems of distribution. The world's food supply is perfectly adequate to feed everyone, and global food production has kept up with population growth. As for overcrowding, the entire population of the world could be housed in an area the size of Texas. This would give every family (or group) of four 5000 square feet of living space.

      The problems of world hunger and overcrowding are not problems inherent with having too many people.

        Your child will only be a child for a short time. I know it is hard when the kid is crying in your face and won't shut up, but take the time to enjoy it. In just a few years the kid will be crying about something else, and a few years latter wrecking your car (unless you teach safe driving by example now, and even then good luck). Then suddenly he is gone and you will realize how much you miss the kid crying in your face.

    One of the effects of hydrogen sulphide exposure is that is "paralyses" the sense of smell before a fatal dose is reached. This is normally very dangerous as people can think they have left the contaminated area while continuing in fact to breathe in more of the toxic gas.

    So chances are you wouldn't have to put up with the smell too long, before you either stop smelling, die horribly or maybe just go into suspended animation.

          The trouble is, not all criminals care about what they've done. Some of them just don't feel pity or remorse.

          CS Lewis argued against a purely penetentiary model of justice on the grounds that it would lead to disproportionate punishment. If we discount punishment as a motive for putting people in jail, then the only reason to send people to jail is to reform them and protect the public. This means that instead of sending people to jail for a fixed time that matches how much punishment the criminal deserves, it is more logical to imprison people until they see the error of their ways and are deemed safe to release. But in some cases this could take a very long time, and there are some criminals who will never be reformed.

          Are we really willing to put people in jail indefinitely? It was proposed here in the UK that "psycopathic" criminals who were judged a permanent danger could be subject to open-ended detention. This met widespread opposition from people who, I assume, feel that jail sentences should fit the crime (ie, they believe in just and proportionate punishment, rather than simply the necessary evil of reformative incarceration).

          As another Slashdotter once put it, imagine if someone was in jail for sharing MP3s online. Should they stay there until they can convince the parole board that they're sorry and won't do it again, even if that takes years? I would say that the punishment for copyright infringement should be proportionate to the harm it causes. Those who make illegal copies should only be punished as much as their crime deserves to be punished. Under a purely penetentiary regime, the whole question of punishment and how much a person deserves to be punished is irrelevant.

          Reforming criminals is a vital part of the justice system, but I wouldn't like a society where it was the only part. I don't believe in insanely heavy penalties for file sharing. Likewise I would be angered if a murderer got off with a light sentence on the grounds that he was unlikely to do it again.

    It's funny that Futurama has the technological development of two distinct and competing technologies for longevity. Fry gets frozen in the chrogenics centre, wakes up in the future and, a few episodes later, discovers that celebrities live on as brains in jars. If we had the technology to keep a human brain alive and kicking I'd much prefer that to getting my head lopped off and frozen in the hope that a sufficiently advanced technology will one day be able to revive me. Even if it ment I had to spend the rest of my days as a body-less paraplegic in a wheelchair I think I'd rather that than to die from cancer.

    Hybernation offers a third technology. Instead of lopping off my head at the first sign of cancer, you could put my body into hybernation and keep my brain active with regular stimulation. Hopefully you could do it by jacking me into a video game. I could handle living in MxO, as long as it was on a non-hostile server. Maybe I could even earn a living as a member of the Live Events team.
    • One thing that they never explained was how the got the heads in jars of people who died long before the technology was developed, like George Washington and Thomas Jefferson. Yeah, I know. It's a cartoon. I shouldn't take it too seriously, but even a funny explanation would do.

    And what strikes me right off (because of my field) is, if a 'hibernation' state can be easily and mobily achieved, you could save a LOT of critical cases by slowing them down right at the point of injury or on the ambulance, maybe even before moving them. That would have a definite positive benefit for sure, though thinking about flying through space in slo-mo is a cool vision too, for sure. =)

  • I'm using some elements of this technology in my next novel (although a lot will get cut in current revisions).

    Hibernation is going to come before any kind of cold sleep or freezing. Kind of silly for science fiction to skip it, even if it is easier on the writer.
    • Arther C. Clarke beat you to it by 30 years.

      In his novels, Hibernation was induced by a variety of things including an enzyme discovered in bears, to the "Dreamless sleep" used by explorers in 2001.

  • That's great news. However, there is no need to ponder possible applications any further because SF authors did that at length over the last 50 or so years. This is just yet another field in which imagination has overtaken reality so now it's just the question of getting it to work. Applications would bloom everywhere as soon as these folks progress from mice to humans.

    Now I'm just waiting for someone to finally find a new energy source.

    The article and research paper note that they placed the mice in the hibernation state for six hours, without any long-term effects. Unfortunately, I can't find in either the article or paper if they tried longer hibernation periods. If they haven't, I suppose that's the next logical thing to try. Looking at their figures, it seems that the 6 hour mark is about when the body temperature finally finishes asymptoting down to the ambient temperature.

    Anyways, here's the research abstract from Science:

    H2S Induces a Suspended Animation-Like State in Mice []

    Eric Blackstone, Mike Morrison, Mark B. Roth

    Mammals normally maintain their core body temperature (CBT) despite changes in environmental temperature. Exceptions to this norm include suspended animation-like states such as hibernation, torpor, and estivation. These states are all characterized by marked decreases in metabolic rate, followed by a loss of homeothermic control in which the animal's CBT approaches that of the environment. We report that hydrogen sulfide can induce a suspended animation-like state in a nonhibernating species, the house mouse (Mus musculus). This state is readily reversible and does not appear to harm the animal. This suggests the possibility of inducing suspended animation-like states for medical applications.

      What about after 6 hours? 80 PPM of H2S shouldn't have much or any affect on anaerobic (non O2 requiring) bacteria, which are found in our gut and mouth. Will people start to "rot" after the six hours because those bacteria shouldn't stop growing.

      Mice are also much smaller than humans (yes a statement of the obvious) and so their thermal mass is much slower - i.e. they cool down MUCH faster due to their increased surface area to mass ratio. I'll try to not become too enthusiastic until I see some larger animal studies - preferrably on cats (not dogs please - I like them) or also on a few of the weird looking guys who hang out at the gas station by my house.

      • Good point. I wonder if this would be a good way to transition to a cryo-like state for longer-term hibernation. One could use H2S to mostly knock out metabolism, then chill the body to slightly above freezing to prolong the effect and hinder bacterial growth. To restore, you'd warm the body back up and remove the H2S.

    Really, I've done this. I hacked my deep freeze to cryogenically freeze me and let me awake in the year 2211. I set up a Unix server to run it all and made sure I had power available until then at least by having my power bill paid from an account into which I deposited $263. I figured the compounding interest over that time would more than pay for the power plus give me a nice nest egg when I awoke. Assuming they still used money in those days. I put myself to sleep on Februray 4th, 2003. Unfortunately I had forgotten to put out dog food for the time I was going to be asleep and poor old Turing (the dog) got a bit restless and he ended up pulling the power on that Unix box. Well, the freezer defrosted, the door popped open and I awoke. First thing I did was turn on the TV. MTV in fact and wow, everything was so different than before. I saw nothing I recognised. I was convinced I had awoken in my choosen time. ThenI looked at my watch and it was February 5th. 2003. Damn the fast moving and ever changing world of popular music.
  • I always wondered why, when I needed to, it was so hard to recruit decent chemists. Nothing to do with the pharmaceuticals companies hiring all the best people, everything to do with entering the inorganic chem lab and going into a state of suspended animation.

    The amazing thing, given the amount of the stuff you use in basic inorganic analysis, is that any of us got any work done at all.

    From eating you alive? Metabolism is down to 10% of normal conditions and almost all of our enzymes have an optimum around 310 K (37 Degrees C). Immune cells won't be very active in hibernation (282 K, 11 degrees C), while some microorganisms flourish at that temperature. Just put a piece of cheese in your fridge, wait two months and take a look to see what the effects can be.

    Actually there's probably already a couple of billion of them on your skin and completely sterilizing a human being (alive) is long from possible. Six hours of hibernation is one thing, but I wouldn't want to try this for more than a day.

      The human ecosystem (body) is host to ~10e14 bacterial cells. A bit more than a couple of billion. Your dirty. Scrub till you bleed if you want, it won't make much of a difference. They are everywhere, on your eyes, in your ears, in your GI tract, in every little pore on your body, all over the skin, in your mouth. Many of your normal flora can be pretty nasty too, if their virulence genes get turned on. You have a lot of Stahpolococcus sp. in your mouth and on your skin. Under the right conditions, they will betray you.

      As for sterilizing a human, even if it was possible, it would be a very bad idea. Your normal flora are adapted to live peacefully side by side with. They protect you by outcompeting invasive foreign species. They manufacture vitamins in your intestines. It would not be a good idea to get rid of them.

      Sterile people can be made in theory. It's been done with mice. Scientists aseptically cut them out of the uterous and raised them in sterile environments. They lived twice as long as ordinary mice, but they were weak and sickly the entire time and died of strange nasty diseases. Some of these sterile mice were exposed to a normal environment. They died soon after of horrible nasty diseases.

      In summary. Long term refridgeration will cause your little buddies to turn on you and sterilization will lead to a bubble life.

      That's a really interesting question - all the same quite a few animals do essentially this for extended periods of some months.

      Why don't their commensal bacteria infect and kill them? That's worth finding out.
  • Imagine this becoming a commodity: you can hibernate through all kinds of rough or simply boring times. Lost your job? Hibernate for 6 months and see whether things have improved. Perhaps something for the loving and caring US government, a way of managing the population?

    Anyway, judging from the research into the life-prolonging effects of calorie restriction this might make people live longer (at least in real, if not in subjective, time)

    How about a religion of sorts for the wise. they sleep and tend-one-another in turns. The membership can be self-supporting with replacments chosen by the group by invitation.

    every x years, a 'class is awoken', it is shown an explination of the last y years developments by the previous class (the previous class is then put into hibernation for a spell).

    each class digests and reflects on humanities progress, problems etc. and issues reports, runs for offices, give grants etc etc etc.

    right now, our insect-like-lifespans cause chaos. there is no incentive to plan long term, there is no incentive to build real solutions to real long-present problems.

    maybe if we all lived longer (or my flight-of-fancy "Cult of the Wise") we would stop thinking about our personal pleasure more and start to think about how to gaurantee pleasure for all... and taking reward in eliminating war, famine, global-pollution etc etc.

    or, we could fly off to other planets - hell i dont know.

    I mean since mice can't talk how do they know how this affects their memories? The normal human brain cannot go without oxygen for 5 minutes, and while oxygen wouldn't be completely cut off from the brain, it would still be greatly reduced. I wonder if this would send the brain into a "skeleton system" type of environment where it keeps on only the bare essentials to survive and therefore shuts out memories. Humans breathe roughly 12 - 20 times per minute, if we apply the rate change of the mouse (1/12 it's normal rate) then humans would be breathing between 1 and 1.5 times a minute. I wonder if this would be enough oxygen for the brain to retain everything that it needs so when the person wakes up they can still perfrom their lives and jobs.
