Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to ...

Researchers have achieved a groundbreaking milestone in studying how vortices move in these quantum fluids. A new study of vortex ring motion in superfluid helium provides crucial evidence supporting ...

A century-old physics question had scientists and mathematicians in knots, until two researchers at the University of Chicago annihilated them. Dustin Kleckner, a postdoctoral scientist, and William ...

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 complex maze of lasers, lenses and mirrors has been used to twist light into a vortex shaped like a doughnut. Vortex rings are common in fluids – think of smoke rings floating in air or underwater ...
