Aflutter in the Breeze

Fabrics flutter in seemingly impossible ways in artist Thomas Jackson's images. But despite first appearances, each photograph is true to life; the fabrics are suspended on taut lines.  (Image credit: T. Jackson; via Colossal)

Mimicking Plant Movement

Many plants control the curvature of their leaves by selectively pumping water into cells that line the outer surface. This swelling triggers bending. Engineers created their own version of this structure. (Image credit: T. Gao et al.; via GoSM) Read the full article

Bending in Bubbles

Inside a cavity with a square cross-section, bubbles form an array. The shapes of their edges are determined by surface tension and capillarity. (Image and research credit: M. Jouanlanne et al., see also)

Nature is full of cilia, hairs, and similar flexible structures. Unsurprisingly, flows interact with these structures very differently than with smooth surfaces. (Image and research credit: C. Ushay et al.)

Desert-dwelling sandgrouse resemble pigeons or doves, but they have a very different superpower: males can soak in and hold 25 milliliters of water in their feathers, which they carry tens of kilometers back to their chicks.

Some water-walking insects are able to leap off a watery interface. One way to model these creatures is with elastic hoops, which can also propel themselves off the water's surface. (Image, video, and research credit: H. Jeong et al.)
