Water expands when it freezes; I do not see how the trillions of ruptured cells (from the micro-shards of ice) constituting the resulting thawed mush of what once had been a functioning system with trillions of parts can be put back together. Until a method of preserving the exquisite micro (and possibly also nano-scale) structures of the brain are developed freezing an organ destroys it. Certain species can freeze and thaw back out and be fine, but they have evolved blood containing anti-freeze in it (which is highly toxic to humans by the way). I am sure DARPA or some such funding agency must be looking at this for humans. Cryogenic preservation must begin with figuring out how to bring the temperature of the preserved tissue down to cryogenic temperatures without so totally destroying the organ (or entire body) that it becomes a case of Humpty Dumpty fell off a wall... In the case of John Clark's brain... he won't care that the information encoded in his brain has just been destroyed by the process -- he paid 80 grand for -- meant to preserve it... because he will have died (and won't miss that 80 grand either I guess) -Chris In either case, duplicated John Clarks will still be rare... -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics [email protected] University of New South Wales http://www.hpcoders.com.au Latest project: The Amoeba's Secret (http://www.hpcoders.com.au/AmoebasSecret.html) ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
