Researchers have uncovered friction without contact—driven entirely by magnetic interactions. As two magnetic layers slide, their internal forces compete, causing constant rearrangements that ...

A Swedish-German-Luxembourg-Chinese collaboration demonstrated the existence of these magnetic hopfions using femtosecond ...

In MFM, a magnetic-coated AFM probe interacts with magnetic field gradients from the sample, causing detectable forces on the probe's cantilever. To focus on magnetic interactions, MFM is often ...

For the first time, scientists have mapped Uranus’s upper atmosphere in three dimensions, tracking temperatures and charged particles up to 5,000 kilometers above the clouds. Webb’s sharp vision ...

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 ...
