Vacuum packed cells survive days to weeks

Vacuum packed cells survive days to weeks

RobertBradbury writes "A group lead by Fred Levine at UCSD is now reporting in Cryobiology (42:207) that simply drying cells in a vacuum is feasible method for cellular preservation. The highly unexpected discovery is discussed in a New Scientist article from October 22, 2001. This potentially provides a very different approach to cryonic suspensions where you would dehydrate the person first, then lower the temperatures to keep them in stasis. No water means no freezing damage due to ice crystal formation. The question becomes whether or not the extracellular structure of the brain (and other tissues) could survive the dehydration process? The shrinkage due to water loss seems like it would put a fair amount of stress on the proteins that bind the synaptic junctions together."

    Question on Biostasis

    What is the best data to suggest that biostasis
    is even theoretically possible in large mammals?
    Has anything larger than an embryo been in a
    state of suspension and revived?

      Re:Question on Biostasis

      A couple of years ago, I read in Nature (or one of those scientific magazines) that they had successfully crogenically frozen a dog for a week and then revived it; the dog did die a few months later – but the fact that it was revived and lived as long as it did is a feat within itself.

      I will try and do a search on the internet tonight and see if an article about this was ever posted and then share it with the forum. If I am unsuccesful in my search, can anyone else here confirm that they read the article as well?

        Sounds like a hoax

        Rob: currently the technology is not available to revive anything bigger than what you mentioned. one of the promises however of advanced nanotech is so that this is in fact feasable. To look at a large mammal though is the same as looking at a single cell..if we have the tech to fix a single cell then we have the tech to fix several…size doesn't matter, tech does. Which is where nanotech comes in.

        Consider doing some research on cryonics and theories behind revival…you might learn some things you cannot yet concieve.

        here is a good start… http://www.alcor.org/

    Metalloids

    How about using a Metalloid like Silicon or something with similiar properties which will not freeze at Absolute Zero to keep the cells 'moisturized' (Does such an element exist?)

    The question is, can the poisons introduced to the cells before freezing be extracted when the times comes for the person/animal to be revived?
