This is the second in a series of interviews with individuals in the life extension and cryonics movement. The first interview was with Cryonics Institute president Ben Best. This interview is with Regina Pancake, Alcor’s Readiness Coordinator.
How did you get involved in cryonics?
My story is not your typical in the details, but in the overall [...]

In 2003 George Hart published an article called “The Immortal’s Dilemma: Decontructing Eternal Life” , making a secular case against immortality.  Hart mainly uses logical arguments and provides a fair amount of room to address a number of possible objections to his position. In a nutshell, Hart considers two variants of immortality, one without [...]

Contrary to popular opinion, in cryonics the blood of the patient is replaced with a cryoprotective agent to reduce freezing, or more recently, to eliminate ice formation altogether through vitrification. This procedure requires surgical access to the circulatory system of the patient to wash out the blood and replace it with a cryoprotective agent. But [...]

“Tenderly you stroke a Nettle, and it stings you for your pains. Grasp it like a man of mettle, and it soft as silk remains.” – Old English proverb
Nearly 20 years ago Alan Sinclair successfully undertook to establish a cryonics facility in the UK. The [...]

In January 2008, Alcor’s self perpetuating Board came under renewed scrutiny after long-time Alcor member and cryonics activist David Pizer tried to raise interest for changing the current system to a member elected Board. Alcor’s most publicly visible response to the arguments raised by Pizer was to publish a document by Board member Ralph [...]

The following announcement from the Alcor Life Extension Foundation is indicative of its renewed focus on professionalizing the organization and improving the quality of readiness and patient care:
On June 7th and 8th, 2008, the Alcor board and management held a 2-day strategic planning meeting at the Alcor facility in Scottsdale, Arizona. At that meeting a [...]

Today’s post on 21st Century Medicine’s vitrification agent M22 completes the series on vitrification agents in cryonics. To date, three different vitrification agents have been used for cryopreservation of humans: B2C (at Alcor from 2001-2005), VM-1 (at the Cryonics Institute since 2005) and M22  (at Alcor since 2005).
Perhaps the most encouraging development in cryonics is [...]

In 2001 the Alcor Life Extension Foundation licensed its first vitrification agent from the cryobiology research company 21st Century Medicine (21CM) to be used for its neuropatients. The composition of this agent, called B2C, has now been made public on Alcor’s website. The published composition is:
Dimethyl sulfoxide 24.765% w/v
Formamide 17.836%
Ethylene glycol [...]

Arthur C. Clark ( 1917-2008 ) was no stranger to cryonics. The famous science fiction author even assisted the cryonics organization Alcor during its legal battles. As he states in a letter in support of cryonics, “Although no one can quantify the probability of cryonics working, I estimate it is at least 90% — and [...]

One scientific question that weighs heavily on the feasibility of contemporary cryonics is what happens to the brain after cardiac arrest. Common wisdom has it that the brain “dies” within 5-7 minutes after circulatory arrest. This is true in the sense that patients resuscitated from such insults die of brain death (or develop higher brain [...]
