Using the magic of magnetic levitation, Harvard University chemists have devised a simple, inexpensive, and portable tool for food and water analysis based on density (J. Agric. Food Chem., DOI: 10.1021/jf100377n). Magnetic levitation, or MagLev, uses magnetic fields to suspend objects. The phenomenon can be applied to measure density and estimate chemical composition on the basis of differences in density. Katherine A. Mirica, Scott T. Phillips, Charles R. Mace, and George M. Whitesides . . .
