PhysicsPhysicists can now take control of 'hidden' friction in devices One type of friction can waste energy even when two perfectly smooth surfaces move against each other, but researchers are getting a handle on how to attenuate or stop it completely News
VideoDoes dark energy stem from a thermodynamic theory of space-time? By studying ripples in space-time, physicists are testing wheather dark energy might stem from hidden dimensions, elusive fields detectable only in deep space, or, even, from the very atoms of space-time itself Video
