Like robots, 3D-printing, space, and a handful of others, laser beams are undoubtedly classified under the “cool” side of science/technology. In the latest laser-beam related findings, Physicists from ...

Physicists have turned a long-standing imaging workhorse into a kind of nanoscale chisel, using a razor-precise ion beam to ...

Imagine a whirlpool spinning in a river, or a tornado swirling through the sky. They don't just spin on the spot: they travel forward while maintaining that spiraling motion inside them. These ...

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

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.
