Shining a light around corners: Scientists explore a new method for curving 'Airy' light beams

We learned in science class that light beams travel in straight lines and spread through a process known as diffraction -- and they can't go around corners. But now researchers at Tel Aviv University are investigating new applications for their recent discovery that small beams of light can indeed be bent in a laboratory setting, diffracting much less than a "regular" beam.
