Boy scouts: forget the moss. A new study shows that cows may sense Earth’s magnetic field
Lost in drive-by country? Look for a cow. It will probably be pointing north—or south.
After analyzing satellite photos of 8,000 cows in 308 different locations, German scientists have found that the milk-makers usually confront the world in a north-south direction. This preference isn’t an indication of the cows sunning themselves, researchers say—it shows that they can sense the Earth’s magnetic field.
