    Do cities need rules?

    Do cities need rules?

    Have you ever thought that your city is too regulated? Or that the city you live in doesn’t do enough to police people who break the rules? In this episode, David Edmonds has been speaking to Michele Gelfand, a psychologist whose research on rule makers and rule breakers could change the way we think about our cities. We’ll find out why you might be able to tell the time better in a city that's like Switzerland; why Japanese police officers reportedly egged people on to commit more crimes; and why living in a city like San Francisco could make you more creative.

    Presented by David Edmonds.
    Produced by Robbie Wojciechowski for the BBC World Service.

    The science of sleep

    We spend around a third of our lives asleep, but the reason we sleep is still something of a mystery. Could it be the biggest mistake the evolutionary process has ever made? What does sleep actually do for us? David Edmonds meets Matthew Walker, one of the world’s leading sleep scientists, to discuss some of his findings. We’ll hear about how the clocks going back has an effect on heart attack rates, and consider why, if you’re struggling to sleep, the worst thing you could do would be to stay in bed.

    The importance of fairness

    The importance of fairness

    Ernst Fehr is well named: he’s an economist who writes about fairness. In fact, until his pioneering work, economists had been dismissive about whether fairness was a subject worthy of study. Now some have tipped Fehr to win a Nobel Prize. David Edmonds speaks to him about why it pays to be fair, and why people are less selfish than you think.
