Invisibility Cloak Created In 3-D 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.

If you think the long lifetime of CFLs is "BS", then the problem is not the bulbs, it's the shoddy wiring in the building. They're sensitive to that. You don't call the canary a useless bird in the coal mine when it keels over. I've had the same two solar-spectrum bulbs in two of my room lights for two years and counting.

Variety, Social Aspects More Important To Game Success Than Graphics, Plot 236

proslack writes "In a study presented at the Human-Computer Interaction conference in Cambridge, England, British researchers Beale and Bond found that plot and graphics are not critical to the success of video games; price and the inclusion of social aspects (e.g. multiplayer or chat) were found to be more important." An unfinished version of the paper (PDF) is available from the researchers' web site. They said, "One of the most unexpected findings was that gameplay was not featured as one of the most important categories to fulfill," though they acknowledge that variety and cohesion were measured separately from gameplay, which past studies have not done.

He's old, so he should die soon.

Rupert, maybe. But his son James here is only in his mid 30s. Like father, like son. We will be cursed with a Murdoch for some time... We can only hope that Jimmy here has only daughters and they go Paris Hilton and becomes a useless heiress. I'd rather have a blonde bimbo than a malignant media mogul.

Don't hit the keys so hard, it hurts.
