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.

Place a level on top of the swing frame, inspecting its horizontal position. Shovel dirt from beneath the legs as needed to ...

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 ...
