Abstract: Spin-exchange relaxation-free (SERF) atomic magnetometers are widely recognized for their ultrahigh sensitivity in weak magnetic field measurements. However, traditional SERF magnetometers ...

Rocks from Australia have given scientists the oldest direct proof that Earth's surface was moving in separate pieces 3.5 billion years ago.

Fusion power promises to generate large amounts of clean electricity from nearly limitless fuel. This article explains the main approaches and the companies that use them.

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory puts that timeline at roughly 5 to 10 billion years in galaxies. Yet ...

Molecular clouds, which are dense areas of gas and dust, are the birthplace of stars. Gravity pulls on material, drawing it ...

A liquid injected into the heart that sets like a gel could one day prevent strokes caused by atrial fibrillation, animal tests suggest.

New observations are helping scientists peer beneath the Sun’s surface, revealing where its magnetic activity may truly begin ...

Scientists have found the oldest direct evidence for tectonic motion on Earth by more than half a billion years ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

The chirality lies in the geometry Scanning electron microscopy (SEM) image of nickel-based artificial chiral magnets fabricated at EPFL’s Center of MicroNanoTechnology. (Courtesy: Mingran Xu, Dirk ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and ...
