In continuing a trend that has seen scientists looking to the mechanics of nature for inspiration, researchers at the Georgia Institute of Technology are studying the ways in which furry mammals shake themselves dry.
Researchers have gained insight on how snakes slither with a simple physics experiment.
A "meniscus"--the crescent-shaped and barely visible slope literally at water's edge--can mean life or death to an insect the size of a speck of dust.
