(Phys.org) —A team of researchers working in Australia has built a tractor beam that bests the distance of other efforts a hundred fold—and it can both push and pull objects. In their paper published in the journal Nature Photonics, the team describes their tractor beam project, how it works and what purpose it might serve.
