The length of Earth’s day drifts by a few milliseconds over decades, and a Nature paper from the University of Alberta argues ...

Tiny changes in Earth’s rotation may reveal a tug-of-war between its deformable inner core, liquid outer core and deep mantle.

Earth's rotation experiences slight variations in day length due to interactions within its inner core and mantle. Researchers have developed a model revealing how gravitational forces drive these ...

If the core froze relatively recently, the current thermal state at the inner core–outer core boundary indicates how much the combined core might have been below its melting point when the inner core ...

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 ...

“It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.” Now, a recent study published in the scientific journal Nature Geoscience reveals a curious new detail ...

Newswise — The surface of Earth’s inner core may be changing, as shown by a new study led by University of Southern California. and University of Utah scientists that detected structural changes near ...

The surface of the Earth's inner core may be changing, as shown by a new study by USC scientists that detected structural changes near the planet's center, published in Nature Geoscience. The changes ...
