Invisibility Cloak Created In 3-D 113 113

An anonymous reader writes "Scientists have created the first device to render an object invisible in three dimensions. The 'cloak,' described in the journal Science (abstract; full text requires login), 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 a true invisibility cloak." The "object" hidden in this work was a bump one micrometer high. The light used was just longer than the wavelengths our eyes detect. To get a visible-light cloak, the features of the cloaking metamaterial would need to be reduced in size from 300 nm to 10 nm.

Submission + - Intel Answers Phenom with Unsupported CPU->

Vigile writes: "Sure the AMD Phenom is getting a lot of attention today but Intel wasn't going to let AMD's parade run without raining on it. In a response that seems more than a little strange, Intel brought in the release of performance data on the Core 2 Extreme QX9770 processor which runs at 3.20 GHz on a 1600 MHz front-side bus. What makes this release odd is that AMD's parts don't even come close to competing with the existing Intel high-end CPUs and that there is no chipset from Intel or elsewhere that actually supports a 1600 MHz FSB! Using current motherboards that were overclocked to run the QX9770, the performance of the new processor is simply the fastest desktop processor we have seen."
