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.

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

Friction is an everyday phenomenon; it allows drivers to stop their cars by breaking and dancers to execute complicated moves on various floor surfaces. It can, however, also be an unwanted effect ...

The debate over whether a war driven oil spike counts as “true inflation” or merly a temporary supply shock is too narrow to be useful. Markets price transmission. Read more ...

Experts from Germany and elsewhere are leveraging water flow friction on the nanoscale level with electrifying results that could power sensors and other tech without a battery. The innovation from ...
