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 ...

Researchers have identified a period of sluggish magnetic field flipping for planet Earth, some 40 million years ago – ...

Add Yahoo as a preferred source to see more of our stories on Google. Over 11 years of satellite data reveal that Earth’s magnetic field is reshaping. (CREDIT: Shutterstock) More than a decade of ...

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard ...

A sediment core from the North Atlantic has revealed that one ofEarth’s magnetic field reversals during the Eocene lasted far ...

Protective force fields exist and you’re already living inside one. About 1,800 miles beneath the ground you’ll reach the border of Earth’s outer core, a subterranean ocean of liquid iron and nickel 1 ...

Past magnetic-field data helps us understand the "geodynamo" — the engine that generates our planet's protective magnetic field. This field is generated by liquid iron slowly moving around the ...

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 ...

Two vast, mysterious blobs of hot rock around Earth’s core may have been instrumental in producing Earth’s magnetic field and caused it to be slightly wonky for millions of years. Scientists have ...

Researchers from the Department of Earth Sciences, University of Oxford, have resolved a long-standing debate about the strength of the moon's magnetic field. For decades, scientists have argued about ...
