There was controversy this week after Ye Shiwen, a young Chinese swimmer, won the 400 metre individual medley in fine style.

Last week's mass-shooting at a cinema in Colorado has - not surprisingly - intensified America's bitter and long-running argument with itself about gun control. The argument is political and highly partisan. But it is also practical: would tighter gun laws actually lead to fewer gun deaths? You might think it's obvious that they would. But it seems the evidence isn't quite that clear. Also: how have Olympians changed in the last century?

Also in the programme: does when you retire influence when you die?

How much damage did messing with Libor really do to the financial system? After all, most financial trades are two way bets – and for every winner, there is a loser.

Do residents of the tiny micronesian island of Palau really smoke more cannabis, and drink more beer, than anyone else?
