In a first, scientists have shown that they can send light through “slits in time” in time. The new experiment is a twist on a 220-year-old demonstration, in which light shines through two slits in a ...

(Aitor Diago/Moment/Getty Images) For the first time, physicists have observed that 'holes' in light can move faster than the light itself. They're known as phase singularities or optical vortices, ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.
