Sidewinding with minimal slip: Snake and robot ascent of sandy slopes
Hamidreza Marvi, Chaohui Gong, Nick Gravish +7
Limbless organisms such as snakes can navigate nearly all terrain. In particular, desert-dwelling sidewinder rattlesnakes (Crotalus cerastes) operate effectively on inclined granul…
Law of Urination: all mammals empty their bladders over the same duration
Patricia J. Yang, Jonathan C. Pham, Jerome Choo +1
Many urological studies rely upon animal models such as rats and pigs whose urination physics and correlation to humans are poorly understood. Here we elucidate the hydrodynamics o…
Entangled granular media
Nick Gravish, Scott V. Franklin, David L. Hu +1
We study the geometrically induced cohesion of ensembles of granular "u-particles" which mechanically entangle through particle interpenetration. We vary the length-to-width ratio…
Can mosquitoes fly in the rain?
Andrew Dickerson, Peter Shankles, Nihar Madhavan +1
Collisions with raindrops are one of many obstacles insects face during flight. In this fluid dynamics video, we present a series of high-speed films of impacts between mosquitoes…
How flowers catch raindrops
Guillermo Amador, Yasukuni Yamada, David Hu
Several species of plants have raindrop-sized flowers that catch raindrops opportunistically in order to spread their 0.3-mm seeds distances of over 1 m. In the following fluid dyn…
The Wet-Dog Shake
Andrew Dickerson, Grant Mills, Jay Bauman +2
The drying of wet fur is a critical to mammalian heat regulation. In this fluid dynamics video, we show a sequence of films demonstrating how hirsute animals to rapidly oscillate t…
Ants as Fluids: Physics-Inspired Biology
Micah Streiff, Nathan Mlot, Sho Shinotsuka +2
Fire ants use their claws to grip diverse surfaces, including each other. As a result of their mutual adhesion and large numbers, ant colonies flow like inanimate fluids. In this s…
