Text of article:

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.
