Cryolophosaurus ellito:
Frozen crested reptile.
Destruction by cold.
A device for measuring very low temperatures.
The measurement or recording of extremely low temperatures, especially using a cryometer.
1. Any of several medical techniques that use cold for therapeutic purposes, such as using ice to deaden pain.
2. The study or practice of keeping a newly dead body at an extremely low temperature in the hope of restoring it to life later with the help of future medical advances; a contraction of cryogenics.
    The following is a summary of the article, “The Ultimate Long-Term Play: Betting on Eternal Life” by Philip Segal in the December 11-12, 1999, issue of the International Herald Tribune, pages 15 and 17.

  • There are risks involved in the nascent business of cryonics, which is the deep freezing at death of human bodies for preservation and possible revival in the future.
  • The biggest problem is that, for now, it is impossible to freeze people and bring them back to life.
  • On the other hand, if cryonics fails, you were already dead anyway.
  • Small wonder that one of the major purveyors of cryonics services, the Alcor Life Extension Foundation, boasts on its Web site that “Since its inception in 1972, Alcor has not lost a single patient.”
  • Although it comes from the same root, kryos, the Greek word for cold, cryonics is not to be confused with the mainstream sciences of cryogenics or cryobiology.
  • These involve freezing of metals or of simple organisms. Metals get stronger after deep freezing, while the freezing and thawing of cancerous tissue can be a good way to kill it.
  • Cryonics seeks to do the opposite. The goal is to freeze a human head (known in the business as a “neuro contract”) or an entire body until the technology exists to graft a new body onto the head, clone a new person from preserved DNA, or heal a sick body that has been preserved.
  • “Cryonics is not a term which is used in any scientific context,” said David Pegg, a professor of biology at York University in England and the editor of the journal Cryobiology. “It is a term invented by people who wish to preserve dead bodies.”
  • Cryonics companies pump what is effectively anti-freeze into the bodies of dead people (referred to as patients) in an effort to stop icicles from forming and damaging cell walls.
  • Getting yourself cryonically preserved costs as little as $28,000 or more than $125,000, depending on whether you pay up front or by the month.
  • The various cryonics businesses encourage people to take out life insurance and use the benefits to cover the cost.
  • The biggest single risk of cryonics is that the company may not be around in 300 to 400 years to unfreeze you, if technology permits.
    It should be noted that humans are not the only bodies that are “cryonized”. When I paid a visit to Alcor for research about cryonics several years ago (in 1993, when it was still in Riverside, California), I was told that some people also had their pets (dogs and cats) frozen so they might also be “animated” (“decryonized”?) sometime in the future.
