Magnetically Levitating Mice | MIT Technology Review Skip to Content NASA engineers have built a device that can suspend mice in the air for hours. The purpose is to understand how zero gravity affects the bone density and muscle mass of astronauts. A three-week-old mouse weighing about 10 grams is being levitated by magnetic fields, either with a magnet (a) or without (b). Credit: Da-Ming Zhu et al. The levitation device, built by Yuanming Liu and colleagues at NASA’s Jet Propulsion Laboratory, uses a magnetic field that distorts the movement of electrons in water molecules to let the mice fl
