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 ...

A new way of producing powerful X-ray beams—the brightest on Earth—is now making it possible to create 3D images of matter at astounding resolutions. This “Extremely Brilliant Source” officially ...
