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 ...

With the rise in popularity of the Oura Ring, I've seen lots of ZDNET readers express interest in finding a more affordable alternative. I don't blame them; while the Oura Ring is a leading smart ring ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

A volcano can casually puff out perfect smoke rings into the sky. There is a simple science behind these rare volcanic vortex rings. Imagine a mighty volcano casually blowing flawless smoke rings into ...

A team of researchers discovered an extraordinary property of vortex rings—how dolphins propel themselves underwater—that science had overlooked for a century. Scientists from New York University and ...

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 ...

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 ...

An innovative “electromagnetic vortex cannon” capable of emitting vortex rings has been created, mirroring the behavior of natural air vortices. This technology could revolutionize communication and ...
