Everyone knows that light travels in a straight line — right? A couple of years back, however, physicists discovered something very different for certain laser pulses that have one intense peak next ...

To investigate the influence of gravity on the propagation of light, researchers usually have to examine astronomical length scales and huge masses. However, physicists have shown that there is ...

Researchers have developed a technique that uses light to get flat, plastic sheets to curve into spheres, tubes or bowls. Researchers at North Carolina State University have developed a technique that ...

LIGHT, which in everyday experience travels in straight beams, has been trapped on complex curved surfaces. The feat is not just a parlour trick – it could help people visualise how light travels in ...
