Moreover, neither of these experiments are vitrification experiments. Both used classical cryobiological freezing techniques http://www.benbest.com/cryonics/cooling.html#classical You do good research, but you too often generalize far beyond what your data justifies. -- Ben Best Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=30517
