A load-bearing wall works to support the weight of the structure, while a non load-bearing wall is simply a cosmetic addition. This means that you can remove a non load-bearing wall without any ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.

Scientists may have discovered how to create a real-life tractor beam using electromagnetic radiation that can draw particles toward it. The result is something very akin to the tractor beam seen in ...
