On a dark winter evening, a woman waits for a train on a deserted platform. A man arrives and sits right beside her, making ...

Tuskegee researchers build a nanoscale photonic crystal sail that reflects propulsion lasers while staying lightweight and ...

Pentagon and FAA agree to anti-drone laser tests in New Mexico after military deployments closed Texas airspace twice.

Combining a database with over 1.5 billion shots, GPS and an ultra-accurate laser, the Arccos Smart Laser goes far beyond distance and slope.

Scientists have successfully tested a material design for light sails using photonic crystals that could achieve 20% the speed of light ...

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

Developed initially for the company's GPS-sensor club performance tracking software, the Arccos course knowledge has been built with data recorded from more than 1.5 billion shots ...

“Top-down” diamond patterning methods, such as reactive ion etching, are difficult given the material’s chemical inertness.

Abstract: Advancements in quantum dot light-emitting diodes (QLEDs) demand fine pixel patterning. However, in the absence of a current blocking layer between pixels, patterning techniques relying on ...

Cheaper than advanced air defenses and more versatile than low-tech options, lasers have become a popular choice for nations worried about drone attacks. By Lara Jakes Lara Jakes frequently writes ...
