On a breezy afternoon last autumn in Cambridge, Mass., in a laboratory thrumming with the huff-whish-huff sound of ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

In the air people breathe, the water on Earth, the stars in the sky and more, atoms are the building blocks that make up the universe. Understanding the structure of the atomic nucleus is crucial for ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can emerge ...

The original version of this story appeared in Quanta Magazine. All the magnets you have ever interacted with, such as the tchotchkes stuck to your refrigerator door, are magnetic for the same reason.

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Somewhere deep inside aging red giant stars, magnetic fields planted during stellar birth may still be humming. A study ...

The muon’s magnetism is still strong. Its most precise measurement yet is in line with a series of earlier results — and seals an embarrassing discrepancy with decades of theoretical calculations that ...

We have, for the first time, a physical path to storing information in the most efficient and fastest way allowed by nature.

When load increases steadily, so does friction, but in the realm of magnetization dynamics, things aren’t so simple.

Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.

If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...
