What is /sci/'s opinion on Cryonics? (better known as cryogenics, even though they're not the same thing).
Defined somewhat as "The practice or technique of deep-freezing the bodies of people who have just died, in thehope thatscientificadvancesmay allow them to be revivedin thefuture."

when u freeze some old guy and unfreeze some old guy he's still old af when u unfreeze him u better get froze when ur young and taut chop chop
Have they ever successfully thawed out mammals before?

I think they did something with a dog at one point.

Same problem as cryogenics - ignoring the lack of motivation, we've never frozen a body without massive cell damage. Not even nanomachines from singularity (which is obviously bullshit) would be able to repair what is left over.
There is a frog in Alaska that can survive being completely frozen. The frog's cells fill up on glucose. Which acts as an anti feeze and prevents water ice crystals from forming. So no cell membranes are damaged.

This. Also, more animals have anti-freeze protection. You just need to avoid ice crystals. We even have food preservation that avoid this. I see a bigger problem restarting the whole brain chemistry to a "normal" state that the freezing per se.

interesting

Interestingly enough, little cell damage is actually caused

i don't know nothing bout that

Citation? I haven't seen "recent" developments, but last I had heard that was definitely not true. As for >>8120872 we could do something similar, but we'd have to figure out a safe way to load every cell in the human body with glucose or a suitable alternative. Possibly also need to deplete it. I very much doubt we're anywhere near doing something like that.

There is a Japanese guys that I saw on NHK that figured out how to use magnets in freezers to store raw fish long term. Apparently the magnetic fields prevent the cells from being burst by ice crystals.
Of course he wasn't making the fridges to store human bodies but rather food so I don't know how well that would translate.
