ESA To Study Human Hibernation 379

colonist writes "The European Space Agency (ESA) plans to study human hibernation for long-duration space voyages (a la 'Alien', '2001'). Although 'practical hibernation mechanisms are at least a decade away', ESA researchers will make initial inquiries into DADLE (D-Ala,D-Leu-enkephalin), an opium-like drug that triggers hibernation in ground squirrels and human cells. Other subjects of interest include dobutamine, a drug that maintains muscle, and the Madagascan fat-tailed dwarf lemur, the only primate known to hibernate."

    Perhaps all long-journey astronauts should be women. There is a well known but seldom used gene present in women that causes immediate hibernation. It has been called the sex-gene. Once the word sex is mentioned the women immediately roll over and are asleep within seconds. This will continue until sex has not been mentioned for at least eight hours. If an automated speaker was constructed to force the sex-gene into operation every 6 or so hours the women should (in theory) remain unconscious.

    This type of research is the future of human space exploration, at least for the forseeable future. Sorry, but light speed, or anything near light speed, just isn't going to happen anytime soon.
    The only downside to this is that the space traveler may seem like the trip only lasted a short time period, when it in fact took 10 years. By the time he gets back home his family will have aged 20 years. It actually may be the closest we get to time travel as well (want to see the future? just hybernate for 100 years).

        It may, actually. Assuming such hibernation significantly reduces the basal metabolic rate, it can be surmised that lifespan would likely be extended. For example, the lifespan of lab rats have been greatly extended by placing them on an ultra-low-calorie diet, and it is theorized that this increase in lifespan is due to the decreased basal metabolic rate resulting from such a diet.

        Sort of. See e.g. this link [earthsky.com]. I think the idea is that it slows aging, but not enough to extend someone's life enough for say interstellar travel. For that we'll need a combination of hibernation and anti-aging mechanisms and anti-disease mechanisms, or some kind of hard stasis (for instance, imagine if you had some kind of nanobot that could separate each individual cell, place each in indefinite stasis, and then reconstruct the whole after a very extended period of time).
    • You often hear geeks lamenting the difficulty in achieving speeds that approach or exceed the speed of light. What people don't realize is that if you wanted to accellerate a spacecraft that didn't weigh very much, say a ton, to anywhere near the speed of light, it would take more energy than the sum of the earth generates in a day or week. Even if the spacecraft and occupants were composed of 100% fissile uranium, you'd still have trouble getting close to the speed of light. e=mc^2.

        Actually e=mc^2 says we've got more than enough energy to spare. The problem is that fission only converts a small portion of the mater into energy. OTOH, antimatter could possibly give us enough energy to reach light speeds. That is, light speeds relative to Earth. From your own position on a space craft, you'd easily exceed light speed relative to the Earth. O

      I wondered the same thing - and going ahead with this, would it be easier to operate on somebody in hibernation?

      Would hibernation be part of a safer anesthetic protocol for surgury? Put the patient into hibernation with local pain killers rather than forcing them into unconsciousness?

      This could be a very useful spin-off of this technology and maybe be more important to humanity than facilitating very long duration space-flight.

          None - the current drugs used to "put somebody under" for surgury and lowering blood pressure/heart rate/respiration are dangerous and require constant monitoring of the patient. If the same function could be provide by a "hibernation drug", I presume that this would be easier on the patient and safer through the course of the surgury.

          • Another problem with general anesthesias is that the entire body shuts down, including the immune system. So your body doesn't have a chance to start healing itself until you wake up. If the body could be staving off infection and mending cuts during the surgery the patient would have a much shorter recovery time with a higher success rate. I'm not sure if hibernation would help with this problem, but it would be interesting to see.

      That would be nice, but unfortunately hibernating is not the same as suspended animation. Hibernating animals still lose muscle mass and use energy. The metabolic rate decreases but does not stop in hibernation.

    • neh, the difference between drug induced sleep and hibernation, is consumption of resources. hibernation means a lowered metabolism, less food consumption, less air to breath... less excretion to handle...

  • Aside from the space travel initiative, this technology could come in handy with people who are sick/dying and would like their dead body frozen. It would be more attractive I think to put someone in suspended animation if they are terminally ill in hopes of a future cure. Because if you are frozen solid by liquid nitrogen after you die; those future scientists will have to figure out how to cure DEATH before they even think about getting to what ails you!

    1. Radiation shielding on long term voyages seems to be a real bear of a problem for manned spaceflight to the planets. It might be feasable to put a bunch of shielding around a small compartment with a hybernaut where it wouldn't be feasable to shield all the working and sleeping areas for an awake astronaut.

    2. By extension, a 2001-like approach becomes workable - Put part of the crew into hybernation, rotate them in and out as needed. In 2001, this was supposed to be because the planetside geologists and such had little to do until Discovery was close to Jupiter, and then the security/paranoia factor kicked in. In the real case, a ship might rotate crew to even out radiation exposure, or put a crewman who was loosing bone mass faster than others into hybernation to protect his health.

    Book Description

    It was a miracle of science that permitted human beings to live, if not forever, then for a long, long time. Some people, anyway. The rich, the powerful--they lived their lives at the rate of one year every ten. Somec created two societies: that of people who lived out their normal span and died, and those who slept away the decades, skipping over the intervening years and events. It allowed great plans to be put in motion. It allowed interstellar Empires to be built.

    It came near to destroying humanity.

    After a long, long time of decadence and stagnation, a few seed ships were sent out to save our species. They carried human embryos and supplies, and teaching robots, and one man. The Worthing Saga is the story of one of these men, Jason WOrthing, and the world he found for the seed he carried.
