For centuries, the homing pigeon carried messages across empires and through storms, its inner compass a mystery that neither myth nor science could fully explain. Now, researchers from four institutions across three continents have traced that compass to its source: iron-laden immune cells in the liver that align with Earth's magnetic field like living needles on a living dial. Published this week in Science, the finding resolves a long debate about how animals sense the planet's invisible lines of force, and reminds us that some of nature's most elegant technologies are written not in stone
