Submission + - Invisibility cloak created in 3-D (bbc.co.uk)

gollum123 writes: Scientists have created the first device to render an object invisible in three dimensions. The "cloak", described in the journal Science, hid an object from detection using light of wavelengths close to those that are visible to humans. Previous devices have been able to hide objects from light travelling in only one direction; viewed from any other angle, the object would remain visible. This is a very early but significant step towards true invisibility cloaks. The basis of the design is known as a "carpet cloak". The trick is to change the speed and direction in which light travels through the material — that is, to change the material's refractive index. The researchers achieved by this using a polymer crystal made up of very tiny rods. By tailoring the refractive index of the the surface of the bump, the scientists rendered it invisible to a wide range of light wavelengths slightly longer than those that we can see. As a result, under this light, the reflective surface appeared to be flat.

Request comparison numbers: "Major agencies cited the exemption at least 70,779 times during the 2009 budget year, up from 47,395 times during President George W. Bush's final full budget year, according to annual reports filed by federal agencies. Obama was president for nine months in the 2009 period." So... that would be an increase of 23,384 denials if my math is right.
