Ultra-Short Pulse Lasers

Scientists at Johns Hopkins University have developed a laser that pulses in femtoseconds, or one millionth of a nanosecond. The laser can be customized to the resonant frequency of any bacteria or virus and will destroy any specific type of organisms in the body of the person it is pointed at. They are currently testing the laser on HIV and Hepatitis with positive results. Moreover, an FDA official estimated that ultra short-pulse lasers (USPs) could have hundreds of medical uses from laser eye treatments to destroying tumors cell-by-cell. USPs also appear to have no negative effect on human cells, although live trials are a long time away.
