Very cool, if true

First, cryonics is not based on deception. To the contrary, it is both scientifically credible (see the Scientists' Open Letter on Cryonics) and supported by the extant scientific literature (see PubMed for a list of some published journal articles on cryonics). There are no known credible technical arguments that lead one to conclude that cryonics, carried out under good conditions today, would not work.

There are loads. It is massively disingenuous of them to claim support from the biological community and literature. During my time as a working biologist, I didn't meet a single other biologist who expressed an interest in cryonics, and the prevailing attitude is, as far as I can tell, is that it makes too little sense to be worth trying to construct a scientifically coherent version to rebut. Their supposed case is all hand-waving - we don't know which features of the brain are important or what sorts of damage they receive soon after death, or from a cryonic technique, so we cannot have any idea whether such a technique exists even in principle that could be reasonably successful.
