Iron atoms discovered on the move in Earth’s solid inner core

A study led by the University of Texas at Austin found that certain groupings of iron atoms in the Earth's inner core are able to move about rapidly, changing their places in a split second. This collective motion could help explain numerous intriguing properties of the inner core and shed light on its role in powering Earth's geodynamo.
