Comment on Mouse brain slices brought back to life after being frozen for a week
Valmond@lemmy.world 1 week agoThere is nothing preventing a rapid cooling the problem is to get water removed/replaced because it creates ice crystals. We can already do this somehow.
The problem with thawing is how do you heat it uniformly.
I have never heard about the laws of thermodynamics would hinder this, any information gladly accepted.
And as for the business, well it’s better than dying, at least there is a chance!

It’s related to thermodynamics but it’s basically the square-cube law: the bigger you get the more your internal volume grows compared to your size.
Heating something large evenly is very difficult because of this. It’s why burritos are lava on the outside and icicles on the inside out of the microwave, or why you need to cook a large roast slowly.

Hopefully we won’t use basic microwaves then :-)
I read about nano particles spread out in the tissues, made to vibrate (probably by EM) to heat up larger portions uniformly.
It’s just a matter of time and effort.

Nanoparticles might do the trick!
