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.

Ancient, giant magnetofossils, formed some 34-56 million years ago, took these magnetic properties to another level, forming unique shapes, including "giant bullets, spindles, and needles," which ...

Imagine crossing vast oceans, soaring across continents, or tunneling deep beneath the earth—without ever getting lost. For some animals, this isn’t just a fantasy, but a daily reality. They possess ...
