Near absolute zero, as atoms slow down, some materials become a superfluid, a type of matter with zero viscosity. Superfluids do all kinds of strange things like generate fountains, leak Keep reading
Saharan Dust
In late January, dust from the Sahara blew westward toward the Cabo Verde archipelago before turning northward toward Europe. During winter and spring, Saharan dust tends to stay at lower Keep reading
Liquid Metal Printing
Engineers have developed a new 3D-printing technique that uses molten aluminum to quickly manufacture large-scale parts. This Liquid Metal Printing method deposits the metal into a bed of tiny glass Keep reading
Moths in Flight
Moths and butterflies are such unique fliers among insects. Compared to their bodies, their wings are often enormous. High-speed video reveals the complex motions of their wing strokes. Some species Keep reading
“Spitting Out Water Babies”
When Tomasz Wilk settled to camp one evening on the banks of a Polish river, he didn’t expect to find fountains in the shallows. Though reminiscent of an archer fish’s Keep reading
Open Call for the Traveling Gallery of Fluid Motion
This year’s Traveling Gallery of Fluid Motion will be hosted in Salt Lake City. There’s currently an open call to scientists and artists for submissions inspired by Leonardo Da Vinci. Keep reading
Serpents and Ouroboros
Beads of condensation on a cooling, oil-slicked surface have a dance all their own in this video. Large droplets gobble up their fellows as they follow serpentine paths; each new Keep reading
Swirls Off South Australia
Summer winds along Australia’s Bonney Coast push coastal waters offshore, triggering the upwelling of colder waters from depths below 300 meters. These cold waters from the deep are nutrient-rich, thanks Keep reading
Skittering Drops
Drip some ethanol on a hot surface, and you’d expect it to spread into a thin layer and evaporate. But that doesn’t always happen, and a recent study looks at Keep reading
Rough Surfaces
In fluid dynamics, we’re often concerned with flow moving past a solid surface — air past an airplane wing, water past fish scales, oil between moving parts — and those Keep reading
