HI everyone!

Here I am again, with the latest issue of PERIASTRON done and sent
to the printer. I will mail it out as soon as it comes back.

Both suggestions in this issue of Cryonet looked like interesting
ones. Sure, they may run into problems on details (how much of the
magnetic substance must be perfused into the patient? does it
conflict with any other compound in the freezing/vitrification
solution?) but that just makes the idea harder to apply. It is
also important, experimentally, to compare this form of warming
with that already suggested, with radio waves (microwaves apparently
don't penetrate enough).

Genetically modifying cells so that they resist the damage of 
freezing better than normal cells looks much harder, but not
impossible. For brains you would need to do this for a very high
% of neurons. It would be a bit easier if the aim were not to 
do the whole job by genetic modification but instead to do
something critical: increased resistance to ischemia, or less
tendency for nerve filaments to be ripped apart by freezing.

		Best wishes and long long life,

			Thomas Donaldson

PS: The reason why application to human beings takes so long 
is an organization called the FDA. The FDA, however, does not
worry about infusions into those declared "dead", so that 
the first plan might be much easier to adopt for CRYONICS
than the second.
