Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better ...

Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

Learn how some of Earth’s magnetic field flips last longer than others, weakening our defenses against cosmic radiation.

Magnetic signatures hidden inside rocks tell us a lot about Earth's magnetic field and the way continents and tectonic plates have shifted across millennia – but for some periods, the geological ...

The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky mantle. According to Biggin, a geologist at the University of Liverpool in the ...

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 years, scientists noticed that magnetic fields could improve steel, but no one knew exactly why. New simulations reveal that magnetism changes how iron atoms behave, making it harder for carbon ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's happening.

Computer simulation of a one-sided magnetic field on early Mars based on data from a study led by the University of Texas Institute for Geophysics. The study could explain the unusual magnetic imprint ...
