Researchers at UNC-Chapel Hill may have proof that sea turtles use the magnetic field of the earth to find their way back to their nesting places after traveling hundreds of miles at sea during adulthood.
Scientists have long suspected sea turtles use their sensitivity to magnetism to locate their hatching sites, but tracking them over long distances and time spans made the theory difficult to prove.
Host Frank Stasio talks with J. Roger Brothers, PhD candidate at UNC-Chapel Hill and lead author of the latest study on sea turtle navigation.
