Surf's Up: How to Catch a Perfect Wave

Along coastlines from California to Australia, you'll see surfers trying to catch that perfect wave. How they find and ride that wave relies on feel and intuition, developed through skill and experience. Now researchers from the LadHyX Hydrodynamics...

A Flounder's Disappearing Act Explained by Physics


Simply oscillating its fins is all a flounder, a flat fish, needs to do to resuspend sand and quickly disappear beneath it to hide. By discovering the physics at play, researchers in France are hoping to provide a new flounder-inspired solution to a...

And When the Bubbles Burst, Thunder in Neurons


In the fleeting moments after a liquid is subjected to a sudden change in pressure, microscopic bubbles rapidly form and collapse in a process known as cavitation. In the human brain, this is believed to be a mechanistic cause of traumatic brain...

Make Mine a Double-Shot, Zero-G Espresso


Last year Italy sent an espresso machine up to the ISS, and this inspired a team of researchers to study the related strange fluids phenomena in low gravity, such as espresso crema formation and containment of potentially hazardous drinks within a...

The Complex Sneeze, Caught on Tape

However commonplace it may be in human life, the sneeze remains somewhat of an enigma to science, and we are still a long way from understanding the simple sneeze in all its phlegm-flam glory. This month during APS’s DFD 2015 Meeting, researchers...

How Does Fur Keep Animals Warm in Cold Water?


Rather than relying on a thick layer of body fat for insulation as many aquatic mammals do, some seabirds and semiaquatic mammals such as fur seals and otters trap a layer of air in their feathers and furs for thermal insulation against the ice cold...

The Spin Racket: Ping-Pong Champs Are Intuitive Masters of Fluid Dynamics

Curve balls may help a pitcher strike out batters in baseball; and some nasty spin can make an opponent sweat to return a tennis serve. But more so than in any other ball game, in table tennis – where the ball is so light and so small –dedicated...

Experts Available: Fluid Dynamics and Ship Experts Discuss the Science of the Costa Concordia

When the cruise liner Costa Concordia drew too close to shore near the Italian island of Giglio, a large rocky outcrop quickly sliced through the ship’s hull. While many questions about the dynamics at play during that disaster remain unanswered,...
