“Magnetite Pollution Nanoparticles in the Human Brain,” PNAS, posted online September 6, 2016.

“This discovery is important because nanoscale magnetite can respond to external magnetic fields, and is toxic to the brain, being implicated in production of damaging reactive oxygen species (ROS).” See also Newsweek story.

“A Sense of Mystery: Researchers from various disciplines are homing in on the mechanics of magnetoreception, an enigmatic sense that some animals use to navigate the globe.” The Scientist, August 1, 2013.

“Most researchers in the field agree that the compass sense is likely seated in cryptochromes within the eye, and many are convinced that there is another sense, most likely a signpost sense, passed through the trigeminal nerve and probably based on some sort of iron-containing, magnetism-sensing cells in beaks or snouts. Then there is [David] Dickman and [Le-Qing] Wu’s idea: that both of these abilities may rely on receptors in the inner ear.”

Weak Fields Can Disrupt Bird Navigation

Very weak radiation can have a profound influence on a robin’s magnetic compass. A group led by Prof. Thorsten Ritz has shown that 7 MHz signals of less than 100 nanowatts per square centimeter can disorient the bird’s migratory flight. The new findings appear in the May 13 issue of Nature.
