LIGHT BEAM WITH A CURVE
A new optics experiment makes a light beam appear to bend in
air. The brightest patch of the beam also appears to travel
with almost no spreading, unlike ordinary laser beams, as a
team reports in the 23 November Physical Review Letters. The
so-called Airy beam may lead to new kinds of optical
engineering.
