Venture near a cave at night, and you may glimpse a phenomenon that still stymies scientists: Thousands of bats streaming out of the cave at high speeds, using echolocation to avoid in-air collisions.

“All we know about science, physics, biology says that [bats are] doing an impossible task by echolocating in these large groups,” says Laura Kloepper, an assistant professor of biology at Saint Mary’s College in Indiana. “What we know about how echolocation works is that when they're in these groups, the signals from each bat should be interfering with each other.”

Why did passenger pigeons go extinct?

Dec 3, 2017

The last passenger pigeon died more than 100 years ago, but scientists still puzzle over how a bird once numbering as many as 5 billion disappeared so quickly from North American skies. “Hunters with guns,” is the big answer — but why didn’t small populations of pigeons survive anywhere?

Modern medicine has reached amazing heights, but even in our own basic anatomy, there are secrets we haven’t quite cracked. For one, as bird veterinarian M. Scott Echols explains, doctors have only a rough idea of where all our veins and capillaries are — and that map is just as vague in animals.
