Hi guys!

First of all, I have a cite for the experiments in growing individual organs
for frogs. The original is in the reports of a conference written up in Science
277(1997) 639-640), 1 August, by Wade Roush. It is the last one, and has
a little headline to itself, "Organs Made to Order".

Second, to Yvan, I would point out that temperature (as in cryobiology)
serves two functions: both to keep the biological material "still", and to
protect it from damage. CO2 is quite low enough for the first, but when 
biological specimens are stored long enough in CO2 they will degrade. No
such degradation occurs in LN2.

Also, Yvan, perhaps because of where you live, you may not have heard of
the work now being done by Paul Wakfer, who is organizing a project for 
exactly what you want: reversible suspended animation. Along the way it will
greatly improve cryonic suspensions, particularly in good cases: the brain,
with all its structures, would be preserved. He calls it Prometheus, and
he can be reached at 70023,3041 on CompuserveA web site for Prometheus has
been set up; it is: http://www.prometheus-project.org/prometheus/. Another
way to get hold of Paul Wakfer is by the address     
		

There has also been an increased interest in cryobiological research by
all of the societies. The Life Extension Foundation (which basically sells
various vitamins and drugs which may increase our lifespan) also underwrites
not only research into therapies for aging but also research into cryonics.
Its principals are both cryonicists, and they use some good proportion of
their profits to support this research.

I have actually discussed these efforts in my editorials in PERIASTRON,
but you may not have bothered to read them. So you know some of this simply
by being a subscriber. It's a bit late for me to do this for the current
issue, which has already gone to the printer; however your question makes
me think that I should give email addresses to the various societies, 
particularly those involved in research ... whenever I discuss them or
their efforts. And of course, if for some reason you aren't GETTING your

issues, please by all means tell me so by letter or email to 

			Long long life,

				Thomas Donaldson
