> The press are likely to have a flurry of interest in cryonics as a result of 
this story, which has been featured on BBC radio and television news. 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.  ... .
