"A breakthrough in precision bullet technology for small caliber firearms will make striking a target an easier task. Two researchers at Sandia's National Laboratories created a self-guided dart-like bullet able to strike a target more than a mile away. \nThe self-guided 4-inch bullet prototype has been successfully tested in both computer simulations and field testing \u2014 where bullet speeds have reached 2,400 feet per second. The bullet differs from missile technology, in that the self-guided bullet has an optical sensor that can detect a laser beam on a target, which allows the bullet to steer toward a target. \nIn one field test, researchers attached a tiny light-emitting diode, or LED to the bullet to tract its path and researchers found the \"battery and electronics could survive the bullet's launch,\" Sandia Lab reported. \nThe bullet is still a prototype, but if it passes further testing conducted by a private firm, the bullet will be accessible to recreational shooters, law enforcement and the military. Lockheed Martin assisted Sandia Lab's research and has worked with the military to develop a self-guided bullet over the years. \n\"While engineering issues remain, we\u2019re confident in our science base and we\u2019re confident the engineering-technology base is there to solve the problems,\u201D Sandia researcher Red Jones said in a statement.\nCheck out the video above to learn more. \nImage courtesy of Sandia National Laboratories \n"^^<http://www.w3.org/2001/XMLSchema#string>
