It took 250 years for the Laschamps reversal to take place and it stayed in the unusual orientation for about 440 years. At most, Earth's magnetic field may have remained at 25 percent of its current ...

A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the Earth’s magnetic field went haywire. The compelling 2021 study tells the ...

Every few hundred thousand years, Earth’s magnetic poles flip, turning north into south and south into north. These ...

At least three explanations are under consideration, each of which could have dramatically reshaped planetary conditions for ...

A new study out this week said that the Earth's inner core is less solid than previously thought. Scientists still have ...

Magnetic field data collected by ESA's Swarm satellites and other sources has been coverted into these frightening sounds.

Earth's inner core has changed shape over the past 20 years. A team of scientists studied the core's behavior to understand why its rotation slowed down ...

“Regarding the impact on life, as mentioned in the paper’s introduction, inner core growth plays a crucial role in generating Earth’s magnetic field, which protects us from harmful solar ...

Combining experiments in microfluidic devices and computer simulation, this study provides a valuable analysis of the relevant parameters that determine the motility of (multicellular) magnetotactic ...

Some of the most sensitive methods of measuring magnetic fields use interactions of resonant light with atomic vapour. Recent developments in this vibrant field have led to improvements in ...

A new study shows that the inner core changed shape in just a few decades, challenging previous assumptions and revealing ...
