Researchers devise method for colorizing metals, alchemists swoon
Unfortunately, Dr. Chunlei Guo of the University of Rochester hasn't yet figured out how to turn scrap metals into gold, but he, along with Dr. Anatoliy Y. Vorobyev, has discovered how to colorize a variety of metals. By utilizing a "femtosecond laser processing technique," the duo has crafted a method for turning even aluminum into aluminum with an impeccable gold finish. Furthermore, they've also been successful in turning tungsten dark blue, leaving reason to believe that nearly any metal could be altered to appear as a different color. Ah, just imagine what these folks could do with your MacBook Pro.[Via The New York Times, thanks Jonathan]
Japanese researchers invent completely transparent material
In a breakthrough that could benefit fields as diverse as networking, photography, astronomy, and peeping, science-types at Japan's Institute of Physical and Chemical Research have unveiled their prototype of a glass-like material that they claim to be 100% transparent. Unlike normal glass, which reflects some of the incoming light, the new so-called metamaterial --composed of a grid of gold or silver nanocoils embedded in a prism-shaped, glass-like material -- uses its unique structural properties to achieve a negative refractive index, or complete transparency. Although currently just a one-off proof-of-concept (pictured, under an electron microscope), mass-produced versions of the new material could improve fiber optic communications, contribute to better telescopes and cameras, or lead to the development of completely new optical equipment.
