My latest story on Beacon is about how cats and other animals manage to always land on their feet. It turns out to be a pretty impressive maneuver, and geckos have evolved and entirely different trick to accomplish the same thing:
There’s no need to go far afield to find wonders of the natural world; sometimes it just takes a shift of perspective to notice how they abound in our homes and neighborhoods. Cats, for example, are exquisite animals, with an uncanny ability to take a fall harmlessly by righting themselves in midair. Several years ago, my cat slipped off a sixth-storey ledge, falling something like 20 meters onto hard concrete. She was limping for a few weeks, but her knee healed and there’s no sign of the injury left. How cats manage such a feat is a question which has occupied scientists for over a century; it’s been the subject of in-depth studies in physics, physiology, and even robotics. While some of the details are still unclear, the essential picture is that cats (almost) always land on their feet thanks to an impressive spine-flexing twist maneuver which turns them upright in midair.
