How Animals Sense Magnetic Fields

Some new findings on this enduring mystery. 
Newly Discovered "Compass" Protein Lines Up With Magnetic Fields | IFLScience: "It took a long time for scientists to believe that animals were capable of sensing our planet’s magnetic field, and while we now know this so-called magnetoreception is very much a real phenomenon, researchers have yet to grasp a deep understanding of how this is achieved. Now, scientists are starting to piece together this complex puzzle, aided by the discovery of a protein complex that aligns itself with magnetic fields."
