Seals use their whiskers to detect tiny vortex rings, seeing through the watery “smoke rings” fish use to escape.

Seals employ extraordinary whiskers to hunt, now proven to decode fish escape strategies. Research shows seals can ...

The study of vortex ring dynamics centres on understanding the formation, evolution and decay of toroidal vortices generated by pulsed fluid jets. These phenomena are crucial in a wide range of ...

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 ...

STORY: Volcanic vortex rings are natural, near-perfect circles of gas emitted from a volcano under specific conditions and scientists say Mount Etna emits more than any other volcano on earth. It is a ...

VOLCANO VORTEX RINGS: Rare volcanic vortex rings were spotted rising above Mount Etna in Italy recently. The natural phenomenon occurs when gases emitted from the volcano ascend rapidly through the ...
