Populus tremuloides, commonly known as Quaking Aspen (or Trembling Aspen, American Aspen, White Poplar, Mountain Aspen etc.), is a deciduous North American tree species endemic to cooler, often mountainous regions.

The thin, flat, flexible petioles on this species make the leaves particularly susceptible to being shaken by even the slightest breeze, hence it’s common name.

The tree can propagate by roots to form large groves. Quiet, breezy days in such groves can sound like a great rain stick sounding in all directions.

Time to get all 500 of these sea star tube feet moving in (slightly out of) sync!

Making lots of progress on my sea star animation. This is the wire frame model of the water vascular system, a hydraulics system that sea stars use to move across the ocean floor.

Viscous liquid placed between two plates forms a finger-like instability when the top plate is lifted. The photos above show the evolution of the instability for four initial cases (top row, each column) in which the initial gap between the plates differs. Each row shows a subsequent time during the lifting process. As the plate is pulled up, the viscous liquid adheres to it and air from the surroundings is entrained inward to replace the fluid. This forms patterns similar to the classic Saffman-Taylor instability caused when less viscous fluid is injected into a more viscous one.   (Photo credit: J. Nase et al.)
