A team of scientists brought ants to the International Space Station, and the insects demonstrated fearless, cooperative exploration just as they do on earth.

Floating in a bag in the microgravity environment of the ISS, the ants had some trouble keeping their footing, but nonetheless persisted -- with remarkable success!-- in performing a collective search of their environment. In fact, roboticists hope to learn from this collective exploration to better design search algorithms. Ants inhabit many environments on earth, but microgravity is a new frontier.

Appropriately enough, these results were published in Frontiers of Ecology and Evolution.
