Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature.

Deep inside Earth, two massive hot rock structures have been quietly shaping the planet’s magnetic field for millions of ...

While we have sent probes billions of kilometers into interstellar space, humans have barely scratched the surface of our own ...

A team of geologists found for the first time evidence linking regions of low seismic velocity and the shape of the Earth’s magnetic field.

A microfluidic system with channels lined with magnetic liquids can ease the flow of samples and safely transport delicate cells, possibly helping to miniaturize microfluidic devices (Nature 2020, DOI ...

Earth’s magnetic field works a bit like a dynamo. It is generated by the movement of molten iron and nickel in the outer core ...

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we ...

Learn about the continent-sized rocks hidden deep within Earth's mantle that have influenced the magnetic field for millions ...

Nematic materials are made of elongated molecules that align in a preferred direction, but, like in a fluid, are spaced out irregularly. The best-known nematic materials are liquid crystals, which are ...

Exploring Earth's deep interior is a far bigger challenge than exploring the solar system. While we have traveled 25 billion ...

A magnetic marker liquid that can help surgeons determine whether breast cancer has metastasised has been recommended for NHS use in England and Wales. Magtrace and Sentimag should be an option to ...
