Laser Turns All Metals Black 333
Roland Piquepaille writes "Researchers at the University of Rochester have found a way to change the properties of almost any metal by using a femtosecond laser pulse. This ultra-intense laser blast creates true 'black metal' from copper, gold or zinc by forming nanostructures at the surface of the metal. As these nanostructures capture radiation, the metals turn black. And as the process needs surprisingly low power, it could soon be used for a variety of applications, such as stealth planes, black jewels or car paintings. But read more for additional references and a picture of this femtosecond laser system."

Hint: Think "perfect stealth", not only for planes, but for your car as well. Make that cop toting the radar gun go insane.

Death to false black metal!

I also noticed that the summary was written (Score:3, Funny)
A laser that turns all metals black. All metals being copper, zinc, and gold. As if these are the only metals around.
Time to wake up. It isn't the bronze age anymore.
