By passing an alternating magnetic field across a magnetic fluid, the particles will heat up, destroying tissue in their path. This method looks promising as a noninvasive means of treating brain tumors, the researcher says. >>> It occured to me that if one were to use a similar fluid as part of a 'blood replacement' therapy BEFORE cryonic suspension (basically ensuring that the tissue is fully permeated with the solution) (or to get really deep future to use nanobots to distribute such a particular mix across the frozen cells which didnt have the solution applied before freezing) that then controlled heating could be applied evenly across the entire cellular matrix at once. This would solve problems associated with uneven or uncontrolled temperature variations during thawing and allow 'digital' (basically through detailed control -- as opposed to analog) control of the rate and amount of heating. This technique could be tested on organs (hint hint -- something for CI to have their researcher try out?) and could be applicable in the near term (and possibly quite valuable if it accomplishes reliable thawing). The material is biologically safe (see the linked article..they're using it for operations within the retina) and availible today (if you happen to have a chemist in your employee). Can somebody look into if this would be helpful in the rewarming stage of cryonics? (I'm just the idea guy ;->) ------=_NextPart_000_0005_01C1E257.6732F730 Content-Type: text/html; [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=18917
