Health trackers like Apple Watches and Oura Rings already do a fine job at providing insights into health patterns and trends. But sometimes, software comes along that offers a little something else ...

The Vortex Optics AMG 1-10X 24 mm FFP riflescope is the shortest and lightest FFP 1-10X low-power variable optic made ...

Air rings blown by dolphins swimming underwater and rings of smoke emitted by jet engines are just two examples of vortex rings. These doughnut-shaped structures and their mesmerizing movement have ...

A European study into Vortex Ring State (VRS) – one of the helicopter industry’s most pernicious and persistent safety risks – has concluded there are only minor differences between the effectiveness ...

This project was inspired by several things—like large vortex cannons used to disrupt hail and a WWII German design meant to bring down aircraft using fuel-ignited vortex rings (though it was never ...

The Thunderstorm Generator—a device using plasmoid and vortex fusion tech—is now producing measurable chemical transmutation, confirmed through independent scanning electron microscope analysis.

COLUMBUS, Ohio – Researchers have developed a new portable tool that could improve how firefighters douse fires, making the process more efficient and far less risky. Built as an alternative to ...

Researchers have developed a 3D-printed device that generates twisting light beams with orbital angular momentum (OAM), a form of rotational energy that can carry more data than regular beams.

Abstract: In this paper, a broadband orbital angular momentum (OAM) vortex beam generator is designed using reflective metasurface. The reflective metasurface is consist of 15×15 rings with ...
