ringleader99: is Notorious B.I.G. an east or west coast rapper?
rasq: He's dead.
rasq: He's black.
rasq: He's a rapper.
rasq: He. Does. Not. Matter.
ringleader99: alright, fair enough.
ringleader99: Is Santa Claus, a north or south pole wrapper?
ringleader99: did you get Portal Prelude yet?!
ringleader99: HUH!?!?!?!?!?
rasq: No.
rasq: I'll download it tonight.
ringleader99: well then
ringleader99: you shouuld get right on to that
ringleader99: you need to graduate to prelude
<This user is now offline>
<This user is now online>
ringleader99: hey
ringleader99: I have a question
<This user is now playing Portal>
rasq: Na?
ringleader99: ok, so you know how plasmids work right? seperate replicating bacteria/mitochondria inside of cells?
rasq: Eh...
rasq: No.
rasq: Biology isn't my strong suit.
ringleader99: aw
ringleader99: AWWW!?
ringleader99: its easy
ringleader99: but no worries
ringleader99: I was wondering if it were possible to create a photosynthetic plasmid inside of human cells, to produce glucose
ringleader99: not to be a walking plant, but so you are able to freeze yourself without your cells becoming damaged by the freezing water within
rasq: ...
rasq: Actually, your cells would still be ruined by freezing.
ringleader99: really? why?
rasq: You can't completely replace the water in your cells with glucose.
ringleader99: thats not how it works
rasq: And you would have to do a lot of tinkerying to work out the bugs.
rasq: *Tinkering.
ringleader99: http://en.wikipedia.org/wiki/Wood_Frog
ringleader99: Similarly to other northern frogs that hibernate close to the surface in soil and/or leaf litter, wood frogs can tolerate the freezing of their blood and other tissues. Urea is accumulated in tissues in preparation for overwintering, and liver glycogen is converted in large quantities to glucose in response to internal ice formation. Both urea and glucose act as "cryoprotectants" to limit the amount of ice that forms and to reduce osmotic shrinkage of cells. Frogs can survive many freeze/thaw events during winter if not more than about 65% of the total body water freezes.
rasq: Interesting, but way out of my area of specialty.
ringleader99: no problem, I am submitting the question to ASU Ask A Biologist
ringleader99: I mean, if it worked, would you freeze yourself?
ringleader99: and reawaken 100 years later?
rasq: Wait, you mean if it was guaranteed?
ringleader99: yeah
rasq: No, I couldn't.
rasq: I'm not a brave man, I'm afraid.
ringleader99: aw, you got to take chances, I mean, if they freeze you, they might be able to reawaken you with future technology
rasq: Knowing that I would go to sleep, and wake up when everyone I know has died, and politicians and good intentions have had another hundred years to screw things up...
rasq: Even if they could reawaken me, I'd have to be critically injured with no other hope of survival before I sign the consent form.
ringleader99: he he
ringleader99: what if some accident were to occour...
rasq: That's what it would take.
ringleader99: what if a robot was sent back in time, with a warning, that the future human race is dying and needs your DNA to repain the human genome, wou would be guarenteed a hiereem of 1000 females
rasq: I'd donate a sperm sample.
ringleader99: but, that doesnt exist i the future
rasq: Honestly, there would be no point in a thousand-female harem.
ringleader99: oh?
rasq: You wouldn't have time to get to know them, to appreciate them for who they are.
ringleader99: what if the future females, were like, super human
rasq: It would degenerate into a chore.
rasq: Superhuman?
rasq: Wie?
ringleader99: yeah, but you have to do it for the sake of the human species
rasq: I can help the human species HERE>
rasq: *Here.
rasq: Anyhow, superhuman in what way?
ringleader99: but the robot said that all the sperm banks were destroyed by the nuclear Holocaust, and the samples that survived, were mutated, causing the human race dying out
ringleader99: they are like, hyper sensual females
ringleader99: ok, the robot corrected it, it is only 25 females
rasq: "Hyper sensual females"?
ringleader99: he he
ringleader99: yeah
ringleader99: hyper sensual
rasq: Yeah, that really doesn't narrow that down.
ringleader99: 21 females, 3 every day, for a week
ringleader99: they are superior in every way
ringleader99: but there are hardly any males, because they are all mutants and degenerates
rasq: And the reason why the females wouldn't be?
ringleader99: the genophage
ringleader99: nearly all future males have contracted a mutant genophage, an aids like virus that current males are immune to
ringleader99: hyper sensual in that they are supremely attractive, as well as hyper intelligent, and they also like your style and attitude, and your behavior and your sense of humor in a perfect manner
ringleader99: as they were selected from all the females on earth, to fit your profile
rasq: Meh.
ringleader99: they are mutlicultural, as well as they all came from different countries, and speak differently
ringleader99: english and german
ringleader99: with accents
rasq: I'd probably end up going to Wal Mart, buying a small tupperware container, and send back a sperm sample.
rasq: Anyhow, I'm a strict monogamist.
ringleader99: dude, the nuclear holocaust
ringleader99: humanity NEEDS YOU!!!
ringleader99: and your just going to turn your back on them
rasq: Would do nothing to a lead-lined sperm sample.
ringleader99: how...GREEDY
ringleader99: no, because all the nuclear missile sites are aimed at our sperm banks, while all our missiles are aimed at our enemies sperm banks
rasq: I'm sending it back with the Robot, genius.
rasq: If they sent that darn thing back in time, presumeably they can bring it back.
ringleader99: no, it works like terminator time travel, not back to the future time travel
rasq: So, how would I be guaranteed safety from the nuclear apocalypse.
ringleader99: the robot self destructed as soon as he delivered the dire message
ringleader99: because his time is 1000 years after the nuclear apocalypse
ringleader99: all civilizations are, hyper sensual
rasq: But seriously, how am I guaranteed safety from the nuclear apocalypse? How do I know that the nukes won't hit me in cyro?
ringleader99: all polotics are the way you want them too
ringleader99: because the robot can shoot your cryo pod into outer space, to travel around the solar system, untill, approxomately 1000 years after the nuclear event, you return to earth, and reawaken
ringleader99: but this cant happen to anyone else
ringleader99: because your specific genome is the only saving grace for humanity
rasq: The robot that self-destructed?
ringleader99: yeah, in the process of shooting you into orbit
rasq: And the reason it won't shoot a lead-lined sperm sample is?
ringleader99: and a sperm sample wouldnt survinve in space, as aliens are patroling for seman samples on our borders, waiting to blow them out of the sky
rasq: Sigh...
ringleader99: ha ha
ringleader99: so, knowing these, highly specific events were to occour, would you save humanity?
rasq: Since this ceased to be a serious questionaire, I would say yes, provided that I get incontrivertable proof that there are no ulterior motives, and I am being squared with 110%, I would then say yes.
ringleader99: oh, there is one catch
rasq: Which you have been waiting ALL this time to spring on me.
ringleader99: no no, the robot was actually a cyborg of you, sent back in time
ringleader99: the thing is, he actually was warning you to NOT go back to the future
ringleader99: because
ringleader99: well, Ill tell you later
rasq: In that case, I wouldn't go.
ringleader99: yeah, but you lied to yourself
rasq: Because I'm not suicidal.
rasq: Unlike the common raghead, I am not willing to die for my 70 virgins.
ringleader99: the future way of speaking, and it happened to be opposite day, so you were programmed with the future language, so you accidentially sent yourelf to the future
ringleader99: but you didnt know it
ringleader99: the thing is about the future
ringleader99: all the females are 100 feet tall
ringleader99: and crush you immediatly upon reentry
ringleader99: but fourtunately, you were reassembled into a cyborg, to deliver a message that you shouldnt travel to the future
ringleader99: but you do anyway
ringleader99: you see where I am going with this?
rasq: No.
ringleader99: well, I am basically trying to explain you somthin, about us east coast wrappers
ringleader99: dont mess with uss, or we will crush you with our future hoes
ringleader99: or we will wrap you up like a cristmas goose, and shoot you off into outer space, to get crushed by our women
ringleader99: dont mess with EAST SIDE!
rasq: Question...
ringleader99: shoot.
rasq: Are you black?
ringleader99: nah
ringleader99: I wish though, those guys really know how to have themselves a good time
ringleader99: what with cyborgs, and giant females, and time travel
ringleader99: thats the idylic setting of thug life
rasq: I hate to ruin it for you...
rasq: But giant women aren't hot.
rasq: And I'll tell you why.
ringleader99: not fat giant
rasq: I know.
ringleader99: like, iron giant, giant
rasq: But even a hundred-foot Pamela Anderson.
ringleader99: iron giant, in amazon woman giant
ringleader99: thats the catch
rasq: You know that mole on her leg?
rasq: Not big, not noticeable to a girl as tall as you.
ringleader99: you tried to warn yourself, but you were only capable of mumbling some inner city slang/ebonics to your past self, resaulting in a series of unfourtunate events
rasq: Ghastly large on a 100 foot chick.
ringleader99: because you offed east side thug life, with your "one female" attitude
rasq: That face that's so beautiful an inch away when she's your size...
ringleader99: ha ha, looking at those pores, gushing out oils
rasq: Pock-marked with huge pores when her face is 15 feet tall.
ringleader99: but remember, they are hypersensual
ringleader99: so they have no pores
ringleader99: nor hair
rasq: I like my hypersensual woman slightly taller than me, or shorter.
ringleader99: nor teeth
rasq: But seriously, what's the point?
rasq: You got to talk about your degenerate East Side life.
ringleader99: they are all thug life, so they have gold teeth or no teeth at all
rasq: Congratulations.
ringleader99: but could you break the loop of time?
ringleader99: what if you said no?
ringleader99: could you say no?
rasq: Yes, I could.
ringleader99: are you still playing portal?
rasq: I was saying 'no' this whole time.
rasq: No, I'm watching District Nine.
ringleader99: thikn of it as a portal, that you decide not to enter, which in tern does not allow you to shoot your portal into a room, that is the same room where you make your decision?
say, christopher robbins, or whatever the devil that cock-a-roach man...

A mildly entertaining conversation with Rasq, which quickly and methodically turned into a temporal black hole.

He probably wouldn't appreciate his secrets foretold to you here, but alas...

All shall be made clear under my grand plan.

Hi Ethan,

Interesting question. Currently the answer is no, there is no known mechanism which would allow humans to be frozen and reanimated unharmed later. While the wood frog does use cryprotectants such as glucose to aid in freeze tolerance, there are a few problems with applying this method to humans. First, wood frogs cannot be completely frozen for long periods of time. They actually only survive if less than 35-45% of their body water freezes. They are able to withstand temperatures of down to -5 or -7C, but this is only for a short period of time, as this method is meant for short-term use (such as a few days of subzero temperatures). In cryonics, it is thought temperatures of -300F would have to be used to preserve a body over time. Thus, rather than using an anti-freeze to avoid complete freezing, I think cryopreservation actually aims to freeze tissue. When ice crystals form in intracellular fluid, it damages or ruptures the cell. Additionally, frog blood cells have a greater osmotic tolerance than human blood cells, meaning they can tolerate a high increase in glucose (and decrease in water) within their cells that we are not able to tolerate, thus this would cause injury to our cells. Finally, freeze tolerant herpetofauna (namely turtles and frogs) have special proteins that control extracellular freezing, and adjust their cellular metabolism to continue to function at low temperatures. Thus, this is not exactly the "suspended animation" that we picture, and even if we were somehow able to use this method, our cellular processes would continue on, which would defeat much of the purpose of avoiding the costs of aging, while waiting for years to pass by.

This only really counts this method out though, as there may be some other method out there we haven't thought of yet.

I hope this helped answer your question. If you are looking for more in-depth information about the processes currently being researched, you should contact a cryonics or cryogenics group (there is a lot of information online), although most of them preserve humans in the hopes that someday we will have the technology to revive them.

Keep asking the hard questions!
