Subject: SCI. CRYONICS Sternberg

Recently I commented that the Darwin group and the Segall/Sternberg group
have apparently been concentrating on longer chilled survival times for
various animals, and that, while good for certain conventional medicine
objectives, this has very limited relevance to cryonics, since most of the
damage occurs in the cryothermic phase, not the hypothermic phase.

But  now Hal Sternberg tells me they have also been doing considerable work
at cryogenic temperatures. He also confirmed an observation we have made at
Cryonics Institute, that individual variation of results is considerable,
even when dealing with healthy animals of the same type. 

With clinically dead humans the variation will doubtless be even greater, so
that prolonged work will probably be necessary, with each procedure, to
establish any kind of reliable average and variance. The availability of
human cadavers in Europe may help.
