Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting ...

That’s why many experts believe sharks navigate by sensing Earth’s magnetic field, perhaps using the same electromagnetic sensory organs that help them track down prey. To test this theory ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests ...

One of these enduring mysteries has been the lunar magnetic field. The Moon generates no magnetic field of its own today. Yet analysis of Apollo rock samples and measurements by orbiting ...

This entire process, from the moment the magnetic field was amplified to the time that it decays back to baseline, would have been incredibly fast -- somewhere around 40 minutes, Narrett says.

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. "The majority of the strong magnetic ...

Magnetic fields are produced by electrical currents that are generated by various astrophysical objects. The study of magnetic fields seeks to understand their origin, as well as the acceleration ...

It has recently been shown that using external magnetic fields to modulate spin states of single-atom catalysts (SACs) is highly effective—enhancing oxygen evolution reaction magnetocurrent by a ...

Geophysicist Daniel Lathrop wants, among other things, to use it to predict when the Earth’s magnetic field will next reverse. Over the course of our planet’s history, the field has flipped ...
