Scientists have developed a new device which levitates mice in the lab. The system uses a superconducting magnet which creates a magnetic field so powerful it causes the water molecules inside the mouse to lift, creating a zero-G effect on the animal. The scientists want to use it to study the effect of bone loss in zero-G environments. I think it's at least as interesting to find out these mice, which are exposed to truly massive magnetic fields, so far show no tendency toward cancer. All those scientists studying whether cell phones and the like cause cancer should likely take note.
