Deep beneath the Earth lies a mysterious and powerful force. A wellspring of nuclear energy which could one day rip us apart.

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

With findings on Earth’s polar extremes and its innermost core, scientists shaped how we look at the planet in 2025 in surprising and fascinating ways.

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

As early as 2024, scientists from the US and China discovered that the Earth’s core had slowed down and even stopped moving in relation to the Earth’s crust. But until now, the general public—that’s ...

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 ...

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 ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

The solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

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.

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 ...
