A team of scientists has identified the cellular machinery in migratory trout that allows them to detect and respond to Earth's magnetic field. Animal migration is one of the great wonders of the natural world. Monarch butterflies, Arctic terns and humpback whales, among other species, travel thousands of miles to escape harsh seasonal weather and find more hospitable climes, like New Yorkers who high-tail it for Florida when the first snowflake drops.
