Flexy Fur Foils Fouling
Inspired by a muddy hike with a dog, today’s study looks at how fur in a flow can shed dirt and debris. Researchers placed beaver, coyote, and synthetic hairs in Keep reading
Scuba-Diving Fly
Mono Lake, three times saltier than the ocean, is an extreme environment by any measure. But for the alkali fly, it’s home. This extremophile insect dives into the lake, protected Keep reading
Bending in the Stream
Nature is full of cilia, hairs, and similar flexible structures. Unsurprisingly, flows interact with these structures very differently than with smooth surfaces. Here, researchers investigate flow in a channel lined Keep reading
Honeybee Feeding
Busy bees feed on millions of flowers for each kilogram of honey they produce. To gather nectar, bees use their hairy tongues, which project out of a sheath-like cover. Protraction Keep reading
Splashes on Hairy Surfaces
The question of whether a droplet will splash is a complicated one, even for smooth surfaces, but researchers are also interested in what happens to hairy surfaces when droplets strike. Keep reading
Hair in the Flow
Humans are hairy on the inside. Not in the way that we are on the outside, but in the sense that many interior surfaces of our bodies are covered in Keep reading
Hairy Surfaces Keep Skin Dry
Big animals like whales and sea lions stay warm in cold waters by having thick layers of insulating blubber. But smaller mammals, like beavers and sea otters, have a different Keep reading
