Funnily enough, humans are also made mostly of water. This is not entirely coincidental. (Cue discussion of mouse-human biological similarities and subsequent suitability of mice as stand-ins for people in experiments.) NASA's trying to find a way to mimic zero-gravity bone loss, so they can find a solution.
Although the first mouse panicked and started doing that spin in midair thing, and the second mouse was sedated beforehand to prevent a repeat, the scientists reported that
[r]epeated levitation tests showed the mice, even when not sedated, could quickly acclimate to levitation inside the cage. After three or four hours, the mice acted normally, including eating and drinking. The strong magnetic fields did not seem to have any negative impacts on the mice in the short term, and past studies have shown that rats did not suffer from adverse effects after 10 weeks of strong, non-levitating magnetic fields.While this is all wonderful and exciting and geeky, if you've been following this blog for a while, you can probably predict my reaction:
What else can we use this to levitate, and how soon can this set-up be commercialized? I mean, we can put water into just about anything, right?
