Peeling ordinary sticky tape can generate bursts of X-rays intense enough to produce an image of the bones in your fingers.
Seth Putterman and colleagues from the University of California, Los Angeles used a motor to unwind a roll of sticky tape and recorded the electromagnetic emissions. Ripping the tape from its roll at 3 centimetres per second generated X-ray bursts of 15 kiloelectronvolts - each lasting one-billionth of a second, and containing over a million photons.
Putterman admits he is not sure exactly what is going on. "My attitude is to marvel at the phenomenon - all we are doing is peeling tape, and nature sets up a process that gives you nanosecond X-ray bursts."

Currently, most nuclear fusion power plants are large, expensive projects that will take decades to benefit from. But a startup company in Vancouver, Canada, called General Fusion is taking the fast track to fusion, with a plan to build a working prototype fusion power plant within the next decade at a cost of less than a billion dollars.

You'd think that dinosaur-loving creationists would be law-abiding citizens. Not so. Last week a South Carolina judge ordered the government to seize control of Dinosaur Adventure Land creationist theme park after its owners were convicted of tax fraud.
