b"This week we look at why ants seem to act much smarter in groups than on their own, and how we can study their swarm intelligence using robots. We'll be speaking with Stephen Pratt, associate professor in the School of Life Sciences at Arizona State University, about how ants in a colony work together to look for things they need, like nest sites and food. Then we'll speak with Simon Garnier, assistant professor in the Department of Biological Sciences at the New Jersey Institute of Technology, about ants that can make living structures out of their own bodies."
