For much of the 20th century, magnetoreception research seemed as unsavory as the study of dowsing or telepathy. Yet it is now an accepted fact that many animals sense the always-on, barely there magnetic field of Earth. Birds, fish, and other migratory animals dominate the list; it makes sense for them to have a built-in compass for their globetrotting journeys. In recent years, researchers have found that less speedy creatures—lobsters, worms, snails, frogs, newts—possess the sense. Mammals, too, seem to respond to Earth’s field. Now, the geophysicist at the California Institute of Technology (Caltech) in Pasadena is testing humans to see if they too have this subconscious sixth sense. http://www.sciencemag.org/news/2016...he-has-discovered-magnetic-sixth-sense-humans
