    [SIZE="6"]Ripped Scotch Tape Emits X-Rays[/SIZE]
    Malcolm Ritter, Associated Press



    Oct. 22, 2008 -- Just two weeks after a Nobel Prize highlighted theoretical work on subatomic particles, physicists are announcing a startling discovery about a much more familiar form of matter: Scotch tape.

    It turns out that if you peel the popular adhesive tape off its roll in a vacuum chamber, it emits X-rays. The researchers even made an X-ray image of one of their fingers.

    Who knew? Actually, more than 50 years ago, some Russian scientists reported evidence of X-rays from peeling sticky tape off glass. But the new work demonstrates that you can get a lot of X-rays, a study co-author said.

    "We were very surprised," said Juan Escobar. "The power you could get from just peeling tape was enormous."

    Escobar, a graduate student at the University of California, Los Angeles, reports the work with UCLA colleagues in Thursday's issue of the journal Nature.
