A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

NPR's Ayesha Rascoe talks to John Vidale, professor of earth sciences at the University of Southern California, about new research suggesting the rotation of Earth's inner core may be slowing down.

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

A new study defies what has been known to humans for decades now, where previous knowledge about the four layers of the Earth sees debunking from this latest discovery. It is common knowledge that the ...
