  The mystery behind animal magnetism and power lines

Photo of article Animals have the ability to navigate by detecting both the strength of the magnetic field emitted by the Earth's liquid core, and the angle at which the field meets the Earth. And research has shown that cows and deer, for example, orient themselves in a north-south alignment. But a Czech-German team of researchers has discovered that the animals' navigating skills go awry when high-voltage power lines are in the area. This latest discovery provides further evidence that animals respond to magnetic effects, particularly because power lines generate a magnetic field. The findings have been published in the Proceedings of the National Academy of Sciences.
