Lasers used to make nanotube yarn

Not satisfied with your Kevlar body armor? Well, you may be in luck. American researchers have used lasers to create the world’s first practical macroscopic yarns from boron nitride fibers. The development could unlock the potential of the material for a wide variety of applications, including radiation-shielding for spacecraft, solar energy collection, and stronger body armor. If the supplied photo is anything to go by, it also does a great job at holding up a quarter.
