Femtosecond Laser Ideal for Killing Cancer, Installing Adamantium Skeletons

/>Did you know that the same ultra-fast, ultra-intense laser (UUL) that can blast individual cancer cells without harming any good cells in the vicinity can also be used to fuse metal to bone? A new laser lab at the University of Missouri has been built to test the awesome power of this system, whose pulses last just one quadrillionth of a second, known in street terminology as a "femtosecond." Here's why the American Dental Association, the American Cancer Society and the Pentagon would be equally interested in this developing technology: More »

Ray Gun Headed for Iraq Battlefield

The United States Army is testing lasers on the battlefield. Ionatron, Inc. of Tucson has developed a weapon called a femtosecond laser, which creates light pulses that last less than 10 trillionths of a second. These pulses carve a channel of ionized oxygen in the air which can conduct electricity. Then, the weapon blasts lightning bolts through these 30-foot channels of conductivity. This is said to be especially good at neutralizing bombs. Ionatron's CEO says his company will be sending 12 of these units to Iraq, the first one by the end of July. More »
