By using sound waves to push and pull matter like science fiction tractor beams, scientists have developed "acoustic tweezers" that can manipulate blood cells and microscopic worms on a platform the size of a dime. http://phys.org/news259916243.html Physics Tue, 26 Jun 2012 07:57:34 EST news259916243 'Tractor beams' of light that pull objects towards them are no longer science fiction. Haifeng Wang at the A*STAR Data Storage Institute and co-workers have now demonstrated how a tractor beam can in fact be realized on a small scale. http://phys.org/news257068727.html Physics Thu, 24 May 2012 09:20:01 EST news257068727 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 particles and delivering them to a robotic rover or orbiting spacecraft for analysis. http://phys.org/news239297920.html Physics Mon, 31 Oct 2011 16:38:48 EST news239297920 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. http://phys.org/news203157529.html Physics Wed, 08 Sep 2010 09:39:09 EST news203157529
