The Trans Time people who have done the experiments with cooling the rats/hamsters/gerbils/whatever used a microwave to thaw the animals they worked with. The blood of the animals was replaced by an experimental solution, then they were cooled to near 0 degrees celsius, then they were thawed quickly with the microwave. This provided a quick, inexpensive way to get a rough idea of how well the experimental solution did its job. Unfortunately, when tissue is cooled to a lower temperature, damage is done during freezing as well as during thawing. Improved thawing techniques are worthwhile, but it can't undo the freezing damage. It would seem that a microwave unit could be built that would aim different units to different areas of the body so that different organs and tissues would thaw at different rates (lots of "differents" in that sentence). If two tissues are in contact and they need to be thawed at different rates, how do we make them get different amounts of microwaves? -- Tim Freeman <> CompuServe ID 71045,2267 checked occasionally. When they took the fourth amendment, I was silent because I don't deal drugs. When they took the sixth amendment, I kept quiet because I know I'm innocent. When they took the second amendment, I said nothing because I don't own a gun. Now they've come for the first amendment, and I can't say anything at all.
