Vortex Trapping Of Suspended Sand Grains Over Ripples

https://doi.org/10.1029/2023JF007620 <-- shared paper
--
“KEY POINTS
• Observations of vortex-trapped grains suggest delayed settling of advected grains, as well as delayed advection of grains mobilized from the bed
• Quantitative comparisons of vortex-trapped sand grains compared well with theoretical formulations by Nielsen (1992, https://doi.org/10.1142/1269) for a forced vortex
• Improved understanding of vortex trapping effects on sediment dynamics may decrease uncertainty in large-scale coastal model predictions..."

The first example of cellular #origami

L. olor is featured in Science because Prakash and Flaum have discovered in this behavior a new geometric mechanism previously unknown in biology. And they are the first to explain how such a simple cell can produce such incredible #morphodynamics, beautiful #folding and unfolding – aka origami – at the scale of a single cell, time and again without fail.

The first example of cellular origami

Combining a deep curiosity and “recreational biology,” Stanford researchers have discovered how a simple cell produces remarkably complex behavior, all without a nervous system. It’s origami, they say.
