... Kind of begs the question about full specimen cryogenic hibernation.

If this is real, and at 500 views, that has taken my top spot as most underrated YouTube video. Top spot was this[0].

That was utterly terrifying to watch, yet the man carrying it out did so with seemingly complete composure. I guess there's really only one type of person that gets to be ~40 years old and disarming mines: one that knows what they're doing, entirely.

Fish can do nonfreezing cryogenic hibernation natively.

And some species of frogs can survive freezing: https://en.wikipedia.org/wiki/Wood_frog#Cold_tolerance

That's truly incredible. Anyone know the details of the 'variable magnetic field'?

Here's a simple video of water bottle cooled to -8C without freezing: https://www.youtube.com/watch?v=fehdWAefXWw

They did mention a 3000 V voltage and mentioned a similar technology developed by a Japanese company. Time for a dig through patents?

Ha, reminds me of coke bottle stored at 0C. When opened, change of pressure made the liquid freeze partially.

In fact this is a common trick people use to make coke slushies: https://www.youtube.com/watch?v=5T68TvdoSbI

Pretty cool, never thought of using it "positively", because when it happened to me randomly, popping the bottle cap trigger a less cute reaction, it basically grew solid tentacles toward the bottom, it was a bit horrifying. I thought it was some bacterial algae ... It became just weird as the busboy brought another one and we saw the same thing happen and the other employees just laughed realizing I just didn't know.

> A Japanese company involved in the development of food-freezing technology invented a special refrigerator, termed as the Cells Alive System (CAS; ABI Co. Ltd., Chiba, Japan).

Aside from the obvious benefit to human life that the article is focusing on, I'm curious how the food preservation can help as well. Does anyone know if this technology is already working to freeze food for commercial use?

Since food does not need to be reanimated, I suppose the benefits will be minimum

(Though the Sushimen in places were freezing is mandated might like it - even though this type might not work since the objective of freezing is killing parasites in fish)

Food that's frozen slowly will grow long ice crystals that act like razors slicing up the cell walls of food. That's why defrosting frozen food often gets you a soggy limp dish.

Food that's "flash frozen" will not develop long crystals that damage food as much and will taste much better after being defrosted.

Here's an article I found. http://www.forbes.com/global/2008/0602/053.html

It sounds very promising for food. I wonder why no one has come out with a consumer product. Anyone want to set up a kickstarter?

I'm curious if this same concept would be useful for other materials? Like metals.

How well would this work for suspended animation for a whole person?
