Tractor beams, energy rays that can move objects, are a science fiction mainstay. But now they are becoming a reality -- at least for moving very tiny objects.
(Phys.org)—A team of scientists from Scotland and the Czech Republic has created a real-life "tractor" beam, as featured in the Star Trek movies, which for the first time allows a beam of light to attract objects.
Physicists at The Australian National University (ANU) have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.
Tractor beams -- the ability to trap and move objects using laser light -- are the stuff of science fiction, but a team of NASA scientists has won funding to study the concept for remotely capturing planetary or atmospheric ...
A team of researchers from the Universities of Bristol and Sussex in collaboration with Ultrahaptics have built the world's first sonic tractor beam that can lift and move objects using sound waves.
Good vibrations: Researchers record first direct observations of quantum effects in an optomechanical system
A long-time staple of science fiction is the tractor beam, a technology in which light is used to move massive objects – recall the tractor beam in the movie Star Wars that captured the Millennium Falcon and pulled it into ...
The first ever landing of a man-made probe onto a comet has been named Physics World Breakthrough of the Year for 2014.
