A single ant isn’t very brainy. But a group of ants can do remarkable things. Biological swarm behavior is one model for the next generation of tiny robots. Of course, biology can get hijacked: a fungus can seize control of an ant’s brain, for example. So will humans always remain the boss of super-smart, swarming machines?

We discuss the biology of zombie ants and how to build robots that self-assemble and work together. Also, how to guarantee the moral behavior of future ‘bots.

And, do you crave cupcakes? Research suggests that gut bacteria control what we eat and how we feel.
