We all know about echolocation, but way more is happening when a bat takes flight, and some bats don't echolocate at all. So how do they have so much precision in their flying and what's different about bats and birds?

SmarterEveryDay looks into the bone structure of bat vs. bird wings and describes how bats have more mass in their wings compared to birds, so their body positions are more influenced by the inertia of their wings. This video even includes some footage of a robobat being developed at Brown. Huh. So this is what it feels like to be crushed under the weight of too many Batman jokes. [SmarterEveryDay]
