Tape + Vacuum = X-rays?

Simply cool, who would have thought you could get x-rays out of tape? Chalk one up for triboluminescence!

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.

This is quite an impressive achievement if you ask me.

Conventional cameras use a curved lens to focus an image onto a flat surface where the light is captured either by film or by digital sensors. However, focusing light from a curved lens onto a flat surface distorts the image, necessitating a series of other lenses that reduce the distortion but tend to increase the bulk and cost of a device.
