We've heard about how gut bacteria might have an impact on things like depression, but a new study shows autism could be related to gut bacteria too. Dr Mauro Costa-Mattioli is froim Baylor College of Medicine, in Houston. He explains what 100 mice have taught him about the link between bacteria and social behaviour.
