It seems the second half of this article is little more than advocacy.

WHERE CAN I GET MORE INFORMATION ABOUT CRYOBIOLOGY OTHER THAN IT IS THE STUDY OF LVING STUFF AT LOW TEMPERATURES ???!!!???!!!
If the study of low temperatures is Cryogenics, then what's the study of high temperatures? Hugh Jass 02:04, 30 September 2005 (UTC)
You will probably not find a lot about cryobiology, because truthfully not many biological processes happen at low temperature. It is, in essence, the study of what doesn't happen at low temperatures (from a biological perspective). Most of the legitimate research would likely be in the area of microscopic cryopreservation (like proteins, cells, etc), in situ cancer treatment, and in the area of food science. The more macroscopic varieties (e.g. freezing Walt Disney or Ted Williams's head) are generally considered pseudo-science.
There is not a corresponding study of high temperatures analogous to cryogenics. The reason is that at low temperatures, not many things happen. So, to generalize, low temperature science is somewhat unified and reaches a single point (absolute zero). At higher temperatures the interactions of matter become more energetic and more varied. Thus there are many fields of study. Some specific fields of study would be combustion, high temperature plasma physics, kinetics, nuclear fusion, etc. Higher temperature sciences diverge to many areas.

NPOV: Removed "pseudo-science" description from cryonics. The paragraph below that location adequately describes cryonics as fringe.

[edit] factually incorrect
What we see here are incorrect statements rewritten from the literature of companies like "300 Below", etc. Heat treated (sound, solid) metals don't have molecular structure as stated below. Ask any student of materials engineering/metallurgy department from any country to correct these statements on heat treating of steels and non-ferrous metals and, also, add related info regarding the completion of martensitic transformation in sub-zero temperatures, residual stresses, and/or stress-induced, 2nd phase precipitation. There are also ASM handbooks and numerous technical publications (conference and peer-reviewed) dealing with the subject of cryogenic metal treatment.
"The theory was based on how heat-treating metal works (the temperatures are lowered to room temperature from a high degree causing certain strength increases in the molecular structure to occur) and supposed that continuing the descent would allow for further strength increases. "
