Technological limitations have made studying friction on the atomic scale difficult, but researchers have now made advances in that quest on two fronts. By speeding up a real atomic force microscope ...

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