Physicists have been hard at work trying take this technology from science fiction to reality. Significant process has recently been made by a team who have developed a laser tractor beam able to attract and repel particles about 100 times further than has been previously achieved. The lead author of the paper, published in <a target=\"_blank\" href=\"http:\/\/www.nature.com\/nphoton\/journal\/vaop\/ncurrent\/full\/nphoton.2014.242.html\"><em>Nature Photonics<\/em><\/a>, is Vladlen Shvedov at Australian National University in Canberra.<\/p>\n<p>Other recent tractor beams have used <a target=\"_blank\" href=\"http:\/\/www.iflscience.com\/physics\/scientists-create-most-powerful-acoustic-tractor-beam-date\">acoustics<\/a> or <a target=\"_blank\" href=\"http:\/\/www.iflscience.com\/physics\/scientists-develop-water-tractor-beam\">water<\/a>, but this one uses a single laser beam to control tiny particles about 0.2 millimeters in diameter. The tractor beam was able to manipulate the particles from a distance of 20 centimeters, shattering previous records. Despite this incredible distance, the researchers claim it is still on the short end of what is possible for this tractor beam technique.<\/p>\n<p>\u201cBecause lasers retain their beam quality for such long distances, this could work over meters.
