In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, ...

"As the magma cooled to form what is today the world's solid outer crust, magnetism was locked into minerals containing iron, such as magnetite." When you purchase through links on our site, we may ...

Susan Clark is helping to unravel the mysterious workings of the Milky Way’s magnetic field, a critical missing piece of the galactic puzzle. Amid the roilings of the Milky Way, immense pockets of gas ...

Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...

There is now a new addition to the magnetic family: thanks to experiments at the Swiss Light Source SLS, researchers have proved the existence of altermagnetism. The experimental discovery of this new ...

Hydrogen is expected to play a central role in future clean energy systems, but storing it efficiently and safely remains one of the biggest challenges to its widespread adoption. Solid-state hydrogen ...
