>Long-term preservation of biological tissue can be achieved by cooling to temperatures below -130°C.[29] Immersion in liquid nitrogen at a temperature of -196°C (77 Kelvin) is often used for convenience. Low temperature preservation of tissue is called cryopreservation. Contrary to popular belief, water that freezes during cryopreservation is usually water outside cells, not water inside cells. Cells don't burst during freezing, but instead become dehydrated and compressed between ice crystals that surround them. Intracellular ice formation only occurs if the rate of freezing is faster than the rate of osmotic loss of water to the extracellular space.[29]
Nature does something like.

sorry, OP
i'm saving my trade secrets, fuck off.
RIP Walt Disney
pls come back
They should figure out how water bears d o it
>tfw you're can't get cryogenically preserved if you kill yourself because you will get an autopsy
>>53740893
You cared enough to clarify.
Shits a meme.
99% of the time they won't be able to legally obtain your body for days or even weeks.
I'd love to do this until the month of February 2017, then again till June that year. Ah.
being cryogenically preserved sounds cool desu. time flies when you don't know whats happening. i imagine it'd be like sleeping and would feel like 5 minutes.
>>53741723
It would feel like nothing because you'd never wake up.
The process they put the rube's bodies through detroys any hope of reconstructing the neurons.
It's flash freezing, but crystals still form and destroy cell walls. A lot of brain function is at way tinier than the cell level, and really can't be reconstructed (ie, it's probably theoretically impossible from information theory)
I don't understand why they can't just clone people and replace their organs surgically to prolong their life.
>>53741760
Oh well that's not what I thought at all, fuck that. I was on the notion that cryogenics would be Sci-Fi Futurama-like, freeze and wake up a few hundred years later
>>53741692
Water bears crack open a lot when frozen.
That's actually how they got a good chunk of their dna

That's the goal, but the technology isn't there yet. If it were a proven method, way more people would do it.

He thinks trips can't be changed. If you filter trips, you're retarded. It literally takes 2 seconds to change your trip.

>It's flash freezing, but crystals still form and destroy cell walls. A lot of brain function is at way tinier than the cell level, and really can't be reconstructed (ie, it's probably theoretically impossible from information theory)
Right:
>Intracellular ice formation only occurs if the rate of freezing is faster than the rate of osmotic loss of water to the extracellular space.
>>53740884
They're not just vegetables anymore
They're frozen veggies!
>>53742448 << Wrong
**Extra**-cellular ice formation destroys cell walls by puncturing them. It helps to do it quickly, but it can't be done quickly enough.
https://en.wikipedia.org/wiki/Cryopreservation#Risks
It's not just intracellular ice that matters. Cell walls have two sides, as it turns out.
>>53740884
would do if is a "Cold boot attack" type process, otherwise is just frozen meat
>>53742539<< possibly wrong
https://en.wikipedia.org/wiki/Cryonics#Preservation_injury
Possibly right:
>When used at high concentrations, cryoprotectants can stop ice formation completely. Cooling and solidification without crystal formation is called vitrification.[34] The first cryoprotectant solutions able to vitrify at very slow cooling rates while still being compatible with whole organ survival were developed in the late 1990s by cryobiologists Gregory Fahy and Brian Wowk for the purpose of banking transplantable organs.[35][36][37] This has allowed animal brains to be vitrified, warmed back up, and examined for ice damage using light and electron microscopy. No ice crystal damage was found;[38] remaining cellular damage was due to dehydration and toxicity of the cryoprotectant solutions.

Would you rather like to rot away, once and for all? Your normie relatives are probably more ok if you rot away btw, they don't want the hassle of having a frozen relative. Once you die you are just meat to ordinary people.
In the end if you don't want to rot, and do want to have a minuscule chance of being revived some day in some form, you'll have to do some hard work (and bring $$$). If you choose not to, one day you simply die permanently and irreversibly.
>b..but freezing doesn't preserve anything!
There were multiple experiments, including the famous one where they took rabbit's kidney, frozen it, then thawed and implanted it back. It worked as a normal one.
Recently there was another experiment that shows that rat brain preserves very fine structural details http://www.brainpreservation.org/

>Would you rather like to rot away, once and for all?
Actually, I'd like to get burned to prevent being revived with Mass Effect tier technology to make me work for them.
>>53743428
Great now you got me wanting to play Mass Effect
Any last words?
>cryogenically preserved
aka dead and frozen
If there is a way to preserve people for a long time, it's not this way
>>53745619
Check out cryonics, used by Alcor. It's a different process, although I don't possess the knowledge to properly vet it.
>>53740884
I gave up on the idea of cryogenic preservation when I read about that company that let a bunch of bodies thaw

They won't ever be able to thaw you. The chemicals they use make your body impossible to resurrect.

>the remaining cellular damage was due to toxicity of the cryoprotectants
I routinely freeze and unfreeze human PBMC's and endothelial cells from our LN2 tank at work. the DMSO the're frozen in is extremely toxic, so you need to do three separate washes with whatever media you're using to culture the cells. Even then, you're getting maybe ~85% viability of the frozen cells, and some of these are very hardy cells. So imagine freezing the most sensitive tissues in your body, things like neurons and HSC's, and losing 40% of them when you thaw. you'd be dead on arrival
