"Fleas are admirable jumpers -- a talent that humans have recognized for thousands of years, according to engineer Greg Sutton. Yet, until this week, exactly how fleas propel themselves wasn't understood. Sutton and Malcolm Burrows, of the University of Cambridge, filmed fleas jumping, analyzed flea anatomy, made mathematical models and cracked the flea leap mystery. It's not in the knees."

I love the comparison with the blinking eye. It's often so hard to get a sense of how fast something is happening in these high-speed videos.
Flea's jump so quickly!
Isn't it neat how fleas have a much shorter time scale relative to humans whereas rocks have an enormously longer time scale comparatively?
As a variable, time is super important to how we understand the natural world.
