Pegasus Posted December 22, 2003 Report Share Posted December 22, 2003 Great reading Andrew, I love this bit... The dehydrated cysts tolerate a much wider temperature range, which never occurrs in nature: absolute zero (-273° C) to almost 100° C.I'm here wondering if the eggs I have will last out, or if I am keeping them too warm... or cold :) They sound almost indistructable. Choice pics as well. Thanks for the link. Quote Link to comment Share on other sites More sharing options...
Interfecus Posted December 25, 2003 Report Share Posted December 25, 2003 The 100C upper limit sounds possible but I'll never believe that anything can survive the process of being frozen to absolute zero until I see it happen with my own eyes.

Ira Posted December 25, 2003 Report Share Posted December 25, 2003 There are quite a few things that can survive being sub freezing temps. I don't think once you're past where everything actually freezes that the rest of the way to absolute zero matters much. But, I don't think most of those that can survive freezing actually completely freeze, I mean most of their non-solid bits probably aren't below the point where they become solid bits on a microscopic level. But bacteria can probably survive, viruses almost definitely. Quote Link to comment Share on other sites More sharing options...
Interfecus Posted December 25, 2003 Report Share Posted December 25, 2003 We're not talking about normal sub-zero temperatures. The few creatures that do survive below freezing only generally survive down to about -20C. These brine shrimp cysts may be able to tolerate lower temperatures than that, but I doubt that any cyst frozen to anywhere below -100C, at any freezing speed, could possibly survive.

Interfecus Posted December 25, 2003 Report Share Posted December 25, 2003 Also, below freezing there is a significant difference towards absolute zero. I've read an article before where it was found that certain frogs could survive to -18C if frozen very slowly but died at any temperature below that.
