A perfectly preserved ancient tree fossil offered scientists an unprecedented view into a moment 42,000 years ago when the ...

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from ...

Sea turtles navigate using Earth's magnetic field like a GPS. Scientists found they learn and remember magnetic locations.

A pair of physicists at the University of Crete has found that some types of biological magnetoreceptors used by various creatures to navigate, operate at or near the quantum limit. In their paper ...

Earth's magnetic field occasionally bursts into song — but these compositions are written with electromagnetic radiation, not sound waves. When converted to audio signals, though, these strange ...

Earth's magnetic field results from a swirling sea of electrically charged molten iron in the planet's outer core. Heat currents and Earth's spin both fuel the movement of this liquid iron.

But never fear — this shape-shifting won’t directly affect life on Earth. Over time, changes to this innermost layer could impact the planet’s magnetic field, which shields our world from solar ...
