This inner core has intrigued researchers since its discovery by Danish seismologist Inge Lehmann in 1936, and how it moves — its rotation speed and direction — has been at the center of a ...

The Earth's inner core was once liquid, but has turned solid over time. As the Earth gradually cools, the inner core expands outwards at the surrounding iron-rich liquid "freezes." That said, it ...

a liquid outer core and a solid and dense inner core made mostly of iron that actually rotates. A study published January 23 in the journal Nature Geoscience finds that this rotation may have ...

Alfred Wilson-Spencer receives funding from NERC grants NE/T000228/1 and NE/V010867/1. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of ...

Scientists have debated for years about what's going on with Earth's inner core. A new study offers compelling evidence that the inner core reversed direction and is slowing down. The shift ...

The new research from the University of Southern California, now published in Nature, noticed that the Earth’s inner core was moving slower than the surface, termed “backtracking,” and has ...

For decades, scientists have tried to understand how Earth’s inner core operates compared with the rest of the planet. Now, a team of researchers has found compelling evidence that it’s ...

Earth's mysterious core is yet again generating headlines as scientists learn more about what lies way beneath our feet. Located 3,000 miles below the Earth’s surface, the inner core is anchored ...

Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can occur at the surface of the Earth’s inner core. This means that the surface of the inner core could ...

The inner core has slowed so much that it has essentially kicked into reverse. The finding by Vidale and his counterpart Wei Wang of the Chinese Academy of Sciences, published recently in the ...

It can also be used in place of dumbbells to perform strength exercises that target the upper body, lower body and core. The ring "tones your inner thighs, arms and core, improves alignment ...
