Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

For over half a billion years, Earth’s magnetic field has risen and fallen in sync with oxygen levels in the atmosphere, and scientists are finally uncovering why. A NASA-led study reveals a striking ...

Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's ...

A recent study published inScience Advances reveals that a temporary collapse of Earth’s magnetic field, known as the ...

Magnetic minerals locked inside artifacts from ancient civilizations reveal a snapshot of Earth's magnetic field at the time. That, in turn, could give us insights into its future. (Image credit: ...

As Earth’s magnetic field has risen, so have the conditions that helped complex life to thrive — a discovery that could aid the search for life on distant planets. The strength of Earth’s magnetic ...

Earth spins, shifts, and now… flips? Our planet’s gymnastics routine continues underneath our feet nearly every day, but researchers at the Helmholtz Centre for Geosciences in Germany recently mapped ...

The strength of Earth’s magnetic field seems to rise and fall hand-in-hand with the abundance of oxygen in its atmosphere, a study of geological records spanning the last half billion years has found.
