It is now widely accepted that many animals sense Earth's magnetic field and use it for navigation, and researchers are getting ever closer to the cellular foundations of magnetoreception. But what about humans? Researchers in Tokyo and Pasadena, California, think they have found glimmers of a vestigial sense. Screening out electromagnetic noise, and applying weak magnetic fields on human subjects in a dark, metal box, the researchers think they have found brain waves that signal a passive response to the fields. But as with many things in the colorful history of magnetoreception research, only time will tell if the results hold up.
