For thirty years, scientists have theorized that it should be possible to create electromagnetic “focused doughnuts” not topologically dissimilar from the vortex rings that form naturally in ...

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 ...

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 ...

Furthermore, research into vortex-ring collisions with density interfaces has clarified the role of buoyancy and baroclinic vorticity generation in altering the translational speed and rotational ...

As a proof of principle, they used strings of 16 vortices to transmit 16,384 pixels, but possible future experiments with strings containing 28 vortex rings would be an efficient way to transmit ...

Vortex rings are not the only unusual signs of activity recently spotted at Mount Etna. On July 20, a new vent opened up in the Bocca Nuova crater, Behncke wrote on Twitter.

Topological monopoles are a quantum physics phenomenon that can decay into what’s known as “Alice rings.” Named after Lewis Carroll’s famous heroine, this vortex ring flips the magnetic ...

The volcano, one of Europe’s most active, has been spewing volcanic vortex rings at a rapid pace. But that doesn’t mean a big explosion is on the way, one expert says.
