New work from a research team led by Carnegie's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions,such as those likely found in the soil's core, where iron predominates and creates our planet's life-shielding magnetic field. Their results, or published in Science,could shed light on soil's early days when the core was formed through a process called differentiation—when the denser materials, like iron, or sunk inward toward the middle,creating the layered composition the planet has nowadays.
