UCLA physicists demonstrated that if you pull off a piece of Scotch tape inside a vacuum chamber, the tape releases enough X-rays to image bones through skin. Grad student Juan Escobar and his colleagues managed to make an X-ray of a thumb using the technique. (Composite image, including the thumb X-ray, below.) Apparently, Russian scientists reported fifty years ago that the act of peeling sticking tape can emit X-rays, but the new research confirms the early results. The latest experiments are presented in this week's issue of the journal Nature. From Nature News:
"At some point we were a little bit scared," says Juan Escobar, a member of the research team. But he and his co-workers soon realized that the X-rays were only emitted when the kit was used in a vacuum. "We don't want to scare people from using Scotch tape in everyday life," Escobar adds.
This kind of energy release – known as triboluminescence and seen in the form of light – occurs whenever a solid (often a crystal) is crushed, rubbed or scratched. It is a long-known, if somewhat mysterious, phenomenon, seen by Francis Bacon in 1605. He noticed that scratching a lump of sugar caused it to give off light.
The leading explanation posits that when a crystal is crushed or split, the process separates opposite charges. When these charges are neutralized, they release a burst of energy in the form of light.
Neglected public payphones in New York City are being turned into “GuyFi” stations: a place where one can rub one out for the sake of “stress relief.” Annalee Newitz reports on the wank booths from a company named “Hot Octopus”… The company reported that at least 100 men used the booth on its opening day […]
You’d be forgiven for thinking the videocassette format long-dead, but it turns out that Betamax is still around. Sony is finally going to withdraw tapes from sale, bringing a 40-year story to an end. The last recorders were sold in 2002. ベータビデオカセットおよびマイクロMVカセットテープ出荷終了のお知らせ [Sony; via The Verge]
A leaked Comcast memo discloses that the company’s consumer data caps have nothing to do with network congestion, contrary to its public claims. The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
