Core body temperature also drops as low as 11C (50F) to match the ambient room temperature. The mice recover in about two hours once normal air/temperatures are applied, with no apparent ill effects - apparently there is a mice IQ/motor-skills test. In addition to the obligatory reference to Woody Allen's Sleeper movie,<http://www.woodyallenmovies.com/movies/sleeper.htm>this has applicability for emergency rooms as it would be beneficial to in ER medicine as a way of "buying time" while diagnosis is performed. *Concerning the reference to Sleeper and the applications of the new technique to cryonics, it is not clear to me if this technique can be used to maintain hybernation for decades instead of hours.* * ------=_Part_689_27869096.1114324706707 Content-Type: text/html; charset=ISO-8859-1 [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=26074
