What role does the mobile phone have in showing off, hooking up and getting dumped? Laurie talks to Emma Bond about her new study into how young people use mobile phones in their intimate sexual relationships.
Also on the programme the historian Teofilo Ruiz talks about the radical thesis of his book the Terrors of History: Is our struggle to find rational solutions to the fearful events of history entirely in vain? Is the idea of progress nothing more than a sweet lie? David Byrne also joins them to discuss whether anything can be done to address the cruel vicissitudes that history makes us suffer.
