A real-life "tractor beam", which uses light to attract objects, has been developed by scientists.
It is hoped it could have medical applications by targeting and attracting individual cells.
The research, published in Nature Photonics and led by the University of St Andrews, is limited to moving microscopic particles.
In science fiction programmes such as Star Trek, tractor beams are used to move much more massive objects.
