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

The relationship between friction and load, quantified three centuries ago, has an exception when the interaction causes magnetic realignment. The discovery won’t let you off the hook when dragging ...

A guidewire is manoeuvred by magnets through a life-sized model of arteries in the brain. The nodules on the arteries represent aneurysms with a high risk of rupture that can cause a stroke. (Courtesy ...
