Sofia Viniegra, Jon Sanders, and Aniek Ivens are biologists interested in the division of labor, interspecific partnerships, and the ecology of mutualisms. In this photo, from the biannual meeting of social insect researchers in the Northeast USA, they are learning how to dissect ants to find out about the diversity of their microbial endosymbionts. The next meeting like this will be held in Philadelphia this spring, click here for more details. There's also a map of social insect researchers worldwide.
