After years of research and experimentation, scientists at the University of St Andrews have successfully created a working tractor beam, even if it limited to microscopic particles at this point. It's doubtful this particular technique will ever reach the scale of a Star Trek-like tractor beam, but the medical applications are promising and serves as a base for further study on a larger scale. Practical scientific theories on real-life tractor beams have been developed since 1960, but it is thought this is the first time a beam has been used to draw microscopic objects towards the light source.
