File this one under Cool Things I Would Have Never Thought Of. In this video, researchers play around with the flow around a spinning top and end up creating a Keep reading

Searching for Stability
At present, there is no theory of relativistic fluid dynamics, which is problematic for those studying black holes, neutron star mergers, and heavy-ion collisions, where fluids may wind up moving Keep reading
DIY Superwalking Droplets
Over the past few years, we’ve seen lots of research in walking droplets, especially as hydrodynamic quantum analogs. But did you know you can replicate this set-up at home and Keep reading
Ascending Through Bubbles
Photographer Lucie Pollet caught this image of her freediving friend ascending through a plume of bubbles and sunlight. I love the otherworldliness of the image, like the diver is an Keep reading
Fluid Flow For Digestive Health
During digestion, our intestines use two different patterns of muscle contraction to move food through our bodies. Scientists have long wondered why we have this added complexity. Using numerical simulations Keep reading
“Reconfiguring It Out”
Leaves flutter and bend in the breeze, changing their shape in response to the flow. Here, researchers investigate this behavior using flexible disks pulled through water. The more flexible the Keep reading
Mixing Effectively
Mixing two fluids is a tougher task than you might think. One of my favorite asides from a fluids lecture concerned how to mix fruit into yogurt in an industrial Keep reading
Cleaning the Skies
Those of us who live in urban environments have experienced the clear, pollution-free air that comes after a rainstorm. But how exactly does rain clean the air? Air pollution typically Keep reading
Beautiful Waves
Australian photographer Ray Collins captures some of the most impressively dynamic photographs of ocean waves I’ve ever seen. The textures of the water range from glassy smooth to scaled to Keep reading
Sound Makes Stickier Bandages
Keeping wounds safe and clean is hard when bandages are so prone to coming off. A team of researchers may have found a solution, though, using ultrasound to enhance adhesion. Keep reading
