You know what we could always use more of? Lasers. Maybe not for burning your eyes or scorching skin, but definitely for cutting and marking inanimate objects. If you've never seen a laser engraver in action before, you'll be amazed at how quickly they can work. In fact, you can make decent images on metal in less than a minute.

A new generation of tabletop accelerators has the potential to accelerate electrons to near the speed of light, without the need for gigantic machines like the Large Hadron Collider. But that all-important energy beam is too spread out for optimal performance. An international team of physicists has figured out a way to address this shortcoming and described their method in a new paper in Physics of Plasmas.
