And, pun intended on the headline; scientists have done some new research on magnetic orientation of animals.
A researcher in Germany thinks foxes use the earth's magnetic field to hunt. I find it dubious, more dubious than the traditionally-breathless New Scientist, but we shall see. If true, it would be the first documented case of a mammal orienting by earth's magnetic field.
And, is Einstein for the birds? Various researchers claim quantum entanglement is part of how birds use the earth's magnetic field!
