Convection isn't always driven by temperature. Here, researchers explore the convective patterns formed by Thiovulum bacteria. (Video and image credit: O. Kodio et al.)

A sudden breeze can pluck droplets hanging from a stem. Here, researchers recreate that phenomenon in the laboratory. With a close-up view and high-speed images, we can enjoy every detail of the detachment and break-up. (Video and image credit: D. Maity et al.)

In mechanical systems, gears and pulleys transmit rotation from one location to another. Here, researchers explore a fluid dynamical version of such systems. (Image credit: J. Smith et al.)

If you fill a test tube with water and drop it, the impact causes a pressure wave that travels up from the bottom and creates a focused jet (left). (Image credit: H. Watanabe et al.)

Breaking a jet of liquid into droplets lies at the heart of many industrial processes: spray painting, fuel injection, and asthma inhalers, to name a few. Here, researchers are looking at a different method of breaking up a liquid jet: shooting a shock wave along its length. (Image credit: S. Rao et al.)

When supersonic jets get emitted into rarefied air, they behave differently than they do in regular atmospheric conditions. (Image credit: S. Lee et al.)

The vivid bands of a gas giant like Jupiter come from the planet's combination of rotation and convection. It's possible to create the same effect in a lab by rapidly spinning a tank of water around a central ice core.  (Image credit: C. David et al.)

When bubbles burst at an interface, both their exterior and interior get spread into the air. Here, researchers watch as a fog-filled bubble rises through silicone oil and settles as the surface.  (Video and image credit: R. Shabtay and I. Jacobi; via GFM)
