Sphagnum moss uses the power of vortices, or rings of rolling air, to launch their spores to extraordinary heights, according to a new study. Vortex-power is essentially the same mechanism ...

With each swim cycle, the jellyfish creates a doughnut shaped vortex in the water, a bit like a smoke ring. The jellyfish resets, contracts, and repeats the swim cycle, creating a second vortex ...

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 ...

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 ...

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.
