By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be perfectly solid. A new study finds evidence that the inner core’s outer ...

Until now, the inner core was widely thought of as a solid sphere. The original aim of the USC scientists was to further chart the slowing of the inner core. "But as I was analyzing multiple ...
