Powerful and compact optical frequency combs provide unique opportunities
Remember those big, clunky machines needed for super precise light measurements? Those days are fading thanks to tiny devices called microcombs. These chips can do the same job, but on a much smaller scale, opening doors for new applications......»»
Harnessing quantum principles: Phased arrays within phased arrays for smarter, greener indoor optical wireless networks
Imagine a future where indoor wireless communication systems handle skyrocketing data demands and do so with unmatched reliability and speed. Traditional radio frequency (RF) technologies like Wi-Fi and Bluetooth are beginning to struggle, plagued by.....»»
Scientists use light to visualize magnetic domains in quantum materials
When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used light to visualize tiny magne.....»»
A quantum material could be the future of high-energy X-ray imaging and particle detection
Scintillators are detectors that make high-energy X-rays or particles visible through flashes of light to form an image. Their many applications include particle physics, medical imaging, X-ray security and more......»»
Apple hosted ‘Global Police Summit’ to help law enforcement use its products better, per report
Typically when Apple and law enforcement are in the news together, it’s because of a standoff over user privacy. But today, a new report outlines the company’s efforts to build bridges with law enforcement—efforts that may be changing. more.....»»
Novel etching technique enhances absorptivity of powders for metal 3D-printing
In a significant advancement for metal additive manufacturing, researchers at Lawrence Livermore National Laboratory (LLNL) and their academic partners have developed a technique that enhances the optical absorptivity of metal powders used in 3D prin.....»»
NASA terminal transmits first laser communications uplink to space
NASA's LCOT (Low-Cost Optical Terminal), a ground station made of modified commercial hardware, has transmitted its first laser communications uplink to the TBIRD (TeraByte Infrared Delivery), a tissue box-sized payload formerly in low Earth orbit......»»
Physics team uncovers a quantum Mpemba effect with a host of "cool" implications
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle's observations two millennia ago and modern-day understanding, while opening the door to a whole host of "cool"—and "cooling"—.....»»
A "forgotten" valley in storm-hit North Carolina, desperate for help
The only road to Pensacola, in the remote mountains of western North Carolina, is now a muddy path through deep, twisting gorges. Its main bridges were swept away last week in floods fueled by devastating Hurricane Helene—and a cold winter is comin.....»»
