X-Message-Number: 29803 From: "John de Rivaz" <> References: <> Subject: Re: microbe longevity in permafrost Date: Fri, 31 Aug 2007 10:23:34 +0100 >>> Analyses of five ice samples, spanning the last 8 million years in this region, demonstrated an exponential decline in the average community DNA size with a half-life of approximately 1.1 million years, <<< I would have thought that this "limit" could be regarded as indefinite as far as cryonics is concerned. If someone remains cryopreserved for any appreciable fraction of a million years this tends to suggest that reanimation is becoming increasingly unlikely as time moves on. The forces of mis-directed commerce and regulation may produce periods of technological stagnation, but these are likely to be hundreds rather than thousands of years. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, de Rivaz genealogy, Nomad .. and Content-Type: text/html; [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=29803
