In this video, learn how to make a custom edge-lit LED sign using laser engraving and woodworking techniques. I’ll show you how to design, etch, and light up your own sign — perfect as a framed ...

Physicists have proposed a new type of laser that could emit powerful bursts of neutrinos instead of light 1. This could enable ‘tabletop’ studies of neutrinos — elementary particles that have no ...

A team of researchers has created a powerful new laser that fits on a microchip. It’s faster, more affordable, and easier to tune than existing precision lasers. The breakthrough could transform ...
