Of course it should be pointed out to any reporters following up the story that this does not revive the personality of the dead mice, even though brain cells were used. Also the mice were frozen at -20C, which is unlikely to preserve them for as long as a lower temperature. > This is a great opportunity for publicizing cryonics, and hopefully increasing the research in cryo in general. One thing this development brings to mind is at one point(s) can mice be brought back from clinical death. I haven't read the research yet, but wonder how damaged the neurons of these frozen mice were. ... . -- Gary Kline http://www.thought.org Public Service Unix http://jottings.thought.org http://transfinite.thought.org Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=31138
