X-Message-Number: 5069 From: Yannis <"yannis"@yannis.seanet,com> Newsgroups: sci.cryonics Subject: Two Mechanisms Date: Sun, 29 Oct 1995 10:38:45 -0800 Message-ID: <470i7i$> I was watching one of the nature shows on TV and they were showing a frog that lives in northern Canada that freezes solid during the winter months and comes back to life in the spring. This is the frog's way of dealing with cold. I am not a scientist but I suspect two mechanisms here. Preservation and kick-start. Somehow this frog has the ability to preserve its tisues during the somewhat slow natural freezing. It may have antifreeze- like substances that control crystal growth. Whatever it does it does it very well considering that it freezes slowly. I don't know if it freezes completely and what the temperature is. All that deserves to be studied. The other thing that needs to be studied is how the frog revives after thawing. Does the nervous system start generating and processing impulses spontanously or is there a temperature sensitive mechanism that stimulates strategic points, kick-starting the animal? Or maybe the nervous system never totally shuts-down? Anyway, this frog may have some aswers. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=5069
