Annotated bibliography of cryoprotectant toxicity
Introduction Cryoprotectant toxicity should be distinguished from other mechanisms of cryopreservation injury such as chilling injury (injury produced by too low temperatures as such) and cold shock (injury produced by rapid cooling). Cryoprotectant toxicity itself can again be divided into … Continue reading

The 2011 Cryobiology Conference
July 24-27 I attended the 2011 annual Society for Cryobiology conference in Corvallis, Oregon. A number of the first presentations were concerned with means to *avoid* cryopreservation. Room temperature storage is much less expensive and troublesome, and improves ease of … Continue reading

Neural cryobiology and the legal recognition of cryonics
It has been said that if you want to persuade someone, you need to find common ground. But one of the defining characteristics of cryonics is that proponents and opponents cannot even seem to agree on the criteria that should … Continue reading

At last, a sure-cold way to sell cryonics with guaranteed success!
A humorous romp through a promising new technique in aesthetic medicine from one cryonicist’s (warped) point of view. Figure 1: Before cryopreservation (L) and after cryopreservation (R). As everyone involved in cryonics for more than a fortnight is sadly aware, … Continue reading

Robert Ettinger on cryonics and research
One of the most common criticisms of cryonics is to argue that cryonics can only be a legitimate endeavor when there is (peer reviewed) demonstration of whole body suspended animation. Advocates of cryonics point out that this is an unreasonable … Continue reading

Cryonics in the media
The Detroit News features a story about cryonics that is a good illustration of the upward battle that cryonics faces in the media. First and foremost, this story reinforces the idea that cryonics concerns the practice of freezing dead people: … Continue reading
The pursuit of cryonics as medicine
The biggest obstacle to the acceptance of cryonics is medical myopia; the idea that someone who has been pronounced dead by contemporary medical criteria will still be considered dead by future criteria. Advocates of human cryopreservation strongly argue against this. … Continue reading

The red blood cell as a model for cryoprotectant toxicity
Various approaches are available to investigate cryoprotectant toxicity, ranging from theoretical work in organic chemistry to cryopreservation of complete animals. Because resuscitation of complex organisms after cryopreservation is not feasible at the moment, such investigations need to be confined to … Continue reading

Armand Karow on Isamu Suda’s brain cryopreservation experiments
In 2007, cryobiologist Armand M. Karow passed away. Unlike many contemporary cryobiologists, Karow offered cautious support for the objectives of cryonics. In the mid-1960s, Karow served on the Scientific Advisory Council of the Cryonics Societies of America (CSA). He also … Continue reading

Greg Fahy on the cryopharmacology of vitrification solutions
In an abstract in Cryobiology 55 (2007), 21st Century Medicine researcher Greg Fahy reports on the biological (pharmacological or “cryopharmacological”) effects of vitrification solutions. He identifies four different mechanisms of toxicity: 1. “Specific toxicity,” or the effects of vitrification agents … Continue reading
Life in non-aqueous solutions
Can life exist without water? This is one of the questions that fascinates astrobiologists. The behavior of biomolecules in non-aqueous solutions is also of interest to cryobiologists and cryoenzymologists. Ice formation below zero degrees Celsius can be prevented by high … Continue reading

Cryoenzymology and cryoprotectant toxicity
The major limiting obstacle to reversible cryopreservation of complex organs is cryoprotectant toxicity. Elimination of ice formation through vitrification requires high concentrations of cryoprotective agents. These high concentrations of cryoprotectants can be toxic to tissues. Over the years, major advances … Continue reading

Cryoprotectant toxicity: biochemical or osmotic?
The current generation of vitrification agents in cryonics permit elimination of ice formation using realistic cooling rates. But attempts to vitrify the brain require high concentrations of cryoprotective agents to inhibit ice formation. Such high concentrations of cryoprotectants can produce … Continue reading
