Cow Compass

New evidence of the hidden talents of cows. Research published in the Proceedings of the National Academy of Sciences suggests that cows have some kind of built-in compass that allows them to align themselves along a north-south axis while grazing in fields. The researchers found this out by studying thousands of satellite photos of cows from all over the world.

But another scientist noted, "the study is based entirely on correlations. To demonstrate conclusively that cattle have a magnetic sense, some kind of experimental manipulation will eventually be needed." That sounds like a bizarre experiment waiting to happen!
