Metropolitan people are often assumed to be quite literally street smart, able to navigate a fast-paced environment with complex transport links, numerous road networks and hidden rat runs. But are people from cities really better at navigating?

New research suggests not. Testing the navigation skills of over four million people via an app-based video game, the scientists behind the study discovered that people who grew up in the country or in suburbs have better spatial skills and can more easily navigate in unknown environments. And people from certain cities, such as Buenos Aires, New York or Toronto, were particularly bad. Here they explain why that might be.

Meanwhile, as the debate continues about the future of public service broadcasting, we look back at the mavericks and rebels who helped shape the BBC. And there’s good news for those looking to reduce their risk of heart disease: eating two or more servings of avocado a week may cut your risk by 16%.
