Water waves can gain energy when they scatter from a whirlpool-like vortex. That is the conclusion of physicists in Brazil, Canada and the UK, who are the first to observe a phenomenon called ...

You walk into an empty room by the sea, to find a perfectly circular hole punched out of the concrete floor where a vortex of water swirls and crashes with perfect rhythm. It sounds like an optical ...

PANAMA CITY BEACH, Fla. (WFLA/CNN) – This is something you don’t expect to see at a hotel pool. A mini-vortex formed in a Panama City Beach pool on Monday. The vortex was captured spinning around the ...

This is the moment an ominous-looking water tornado loomed over a port city in southern Cuba. Stunning footage of the weather phenomenon shows the huge funnel-shaped waterspout spiralling down from ...

The world’s river and ocean currents carry an enormous amount of kinetic energy, but most of this water flows slower than four miles per hour. Existing turbine and water-mill technologies can’t ...

Life is complex. So is fluid dynamics. Actually, you’d think fluid motion isn’t all that complicated. Liquids flow downhill, moving around stationary objects, and generally going from point A to point ...

Short pulses from a laser can be twisted into a series of doughnut-like vortices, offering a way to transmit more information using light. We usually encounter vortices in water and air, but similar ...
