In his 1998 essay “The Failure of the Cryonics Movement” (part 1, part 2), Saul Kent stresses that cryonics has remained so unpopular because nobody thinks it will work. One observable implication of this view is that we would expect to see broader acceptance of cryonics as its technical feasibility increases. Unfortunately, there is [...]

Few, if any, cryonicists today can retrace their personal interest in cryonics to Evan Cooper. Despite the broader recognition of Robert Ettinger’s book, “The Prospect of Immortality,” which was commercially published in 1964, Cooper’s privately published 1962 manuscript, “Immortality: Physically, Scientifically, Now,” is an important parallel effort in what would later become known as cryonics.

Methuselah Foundation Announces Aging 2008 at UCLA
Have you ever dreamed of climbing Mt. Everest – on your 125th birthday?
Los Angeles, CA (May 19, 2008) On Friday June 27th, leading scientists and thinkers in stem cell research and regenerative medicine will gather in Los Angeles at UCLA for Aging 2008 to explain how [...]

The idea that cryonics does not involve the freezing of “dead” people but is form of low temperature care to prevent death is almost as old as the idea of cryonics itself. In May 1968, Cryonics Reports, the publication of the Cryonics Society of New York (CSNY), writes that recognition of cryonics as a [...]

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 injury to tissues that is distinct from damage caused by ice formation.
Vitrification of complex tissues [...]

In “Heritage of Horror,” Lovecraft scholar S.T. Joshi writes that Lovecraft’s short story “Cool Air” “anticipates cryogenic research.” We can forgive Joshi the common mistake of writing “cryogenics” when he means “cryonics,” but how much cryonics is there really in Lovecraft’s “Cool Air?”
“Cool Air” (1926) tells the story of a struggling writer who has secured [...]

The practice of balneotherapy, also known as water treatment or spa therapy, has experienced a resurgence in popularity in recent years, especially amongst those with skin diseases such as psoriasis and atopic dermatitis. Salts, minerals, and bacteria particular to certain geothermal springs in various locations throughout the world have long been touted as having [...]

Because the current generation of vitrification agents permit cryopreservation of the brain without ice formation, the current objective of cryonics research is maintenance of viability of the brain during cryopreservation. The most popular viability assay that has been used in cryonics and cryonics-associated cryobiology research is the potassium/sodium ratio (K+/Na+ ratio). Because the ability [...]

Cryonics Reports was the publication of the Cryonics Society of New York (CSNY). In April 1968 a call to arms to conquer aging was published. This editorial stressed that the problems of aging will not be solved until we decide that we want to conquer aging and extend our lives.

In his January 2008 Journal of Emergency Medical Services (JEMS) article, “Nothing but the Truth,” Criss Brainard provides examples of two cases where voice recording technology could aid in clearing the names of emergency personnel who had been accused of inappropriate conduct during patient transport. While cryonics standby team members may not need to worry [...]

After legal pronouncement of death, cryonics patients benefit from rapid stabilization to protect the brain from injury. The most fundamental intervention is induction of hypothermia. Unlike other interventions such as cardiopulmonary support (CPS) and administration of neuroprotective medications, induction of hypothermia is an intrinsic part of cryonics. Unfortunately, surface cooling with ice is not a [...]

Before the scientific conquest of death became a serious topic of conversation, philosophers, writers and poets had to resign themselves to the inevitable demise of the individual in this world. Jeremy Taylor (1613-1667), the “Shakespeare of Divines,” gave poetic expression to the brevity and fragility of life in his The Rule and Exercises of [...]

One concern about chemical fixation as a low cost alternative to cryonics is that current fixatives may not be able to permanently fix all biomolecules that are important to preserve the identity of the person. A related concern is that postmortem delays may not permit adequate perfusion of the brain, resulting in pockets of [...]
