Subject: Higher Temperature Storage 

In view of Doug Skrecky's posting, #13841, we can ask of the higher
temperature storage that has been proposed as an accompaniment of a new
suspension protocol would really be best for longterm preservation of
identity-critical information. The higher-temperature storage may indeed
lead to reversible cryopreservation, yet over many decades it could still
promote degradation of memory information in the brain that would not occur
at liquid nitrogen temperature. The cracking that occurred in lowering to
this temperature might still be a favorable tradeoff. Something to
investigate. Actually, though, I am inclined to optimism about storage of
brain tissue at -130, in view of the successes Suda had with brainwave
recovery at the much higher storage temperature of -20.
