Cryoprotectant found in some Insects and Amphibians to survive the deep freeze!!

In the news say Insects and Amphibians survive the deep freeze by Cryoprotectant!! They say scientist are looking into Cryoprotectant as holy grail of Cryopreservation turning Cryopreservation science fiction into reality.  Where one of major problems with Cryopreservation today that make it science fiction is when you freeze the human body you get ice crystals that damage cells, tissues, organs, brain cells and DNA. So the body is  very damage and not preserved in the state was before freezing.

Where despite billions dollars put into Cryopreservation to date they have not found the holy grail to stop ice crystals!!

Talking about antifreeze. I'm not sure how workable it will be for us, though there's a dessiccation based method that might work instead.

Strictly only need hibernation rather than freezing. Sometimes we pull this off in accidents, but needs to be reliable rather than random.

You assuming antifreeze will work and not cause ice crystals?

Sure, they work to lower the temperature something will freeze at(creating ice crystals). The trick is to find one that is also safe for us.

Not sure why they used the term cryoprotectant, most people have at least a passing familiarity with antifreeze.
