There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

Researchers have made a new discovery that changes our understanding of Earth's early geological history, challenging beliefs about how our continents formed and when plate tectonics began. A study ...

Continental clues: Modern continental rocks carry chemical signatures from the very start of our planet’s history, challenging current theories about plate tectonics. Researchers have made a new ...
