Ants on treadmills…for science!

Few things are as entertaining as watching animals on treadmills. Although Penguins might be the cutest, these ants are pretty fun, too. Here, researchers set up a hollow styrofoam ball floating on a stream of air as a treadmill for desert ants. To keep the ants from wandering (or simply falling) off the treadmill, the scientists glued the thorax to a small pin. They then were able to precisely track the animals’ movements and behavior as they navigated to their nests. Check out the video (below
