Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

Migratory birds can extract positional information from magnetic inclination and magnetic declination alone. Proceedings of the Royal Society B: Biological Sciences , 2024; 291 (2034) DOI: 10.1098 ...

Earth is a giant magnet, explains science writer Ned Rozell. So the difference in the two, known as degrees of declination, changes depending on where you are.

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

While life on Earth has weathered multiple magnetic reversals over more than 100 million years, “we’ve never experienced a ...

“We find that both exhibit strong linearly increasing trends, coupled with a large surge in magnitude between 330 and 220 ...

Every breath we take in contains 21% oxygen, the gas that makes life on Earth possible. Oxygen, in its combined oxide state, ...

Your navigation system just got a critical update, one that happens periodically because Earth’s magnetic north pole keeps moving. Here’s what to know.

While life on Earth has weathered multiple magnetic reversals over more than 100 million years, “we’ve never experienced a reversal when modern technology was present,” Brown said.
