(Phys.org)—Physicists have proposed a way to braid three beams of light by guiding the beams along swirling, vortex-shaped defects in the optical medium through which the beams travel. The braided light would have an unusual ...
Scientists have built a computer model that shows how bees use vision to detect the movement of the world around them and avoid crashing. This research, published in PLOS Computational Biology, is an important step in understanding ...

A large team of researchers with members from MIT, IBM, NASA's JPL and Columbia University has developed a process that that enables scalable integration of superconducting nanowire single-photon detectors (SNSPDs) on a range ...
(Phys.org) —It was a big week for discovery as a Star Trek-like invisible shield was found thousands of miles above Earth—it's in the Van Allen radiation belt and appears to protect the planet below from "killer electrons." ...
