Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

The Earth’s magnetic field does more than just cause auroral light shows. Could it play a role in extinctions, too? After studying the reversal of Earth’s magnetic pole known to have occurred 42,000 ...

Add Yahoo as a preferred source to see more of our stories on Google. Wandering magnetic fields would have had noticeable effects for humans. Maximilian Schanner (GFZ Helmholtz Centre for Geosciences, ...

An illustration of what the aurora might have looked like during a polar reversal about 41,000 years ago. Earth’s magnetic field is created by its rotation, as well as the rotation of our planet’s ...

A study suggests that Homo sapiens may have benefited from the use of ochre and tailored clothing during a period of increased UV light 41,000 years ago, during the Laschamps excursion. Ancient Homo ...

Thanks to auroras and other space weather, humans have adapted techniques to overcome these issues.

Our first meeting was a bit awkward. One of us is an archaeologist who studies how past peoples interacted with their environments. Two of us are geophysicists who investigate interactions between ...
