Confusion surrounds the second round of talks scheduled in Pakistan between US and Iranian officials.

Also in the programme: We speak to Arab Barghouti, son of the prominent Palestinian prisoner, Marwan Barghouti. In 2004 an Israeli court found Marwan Barghouti guilty of five counts of murder as well as membership of a terrorist organisation. The court found there was insufficient evidence connecting him to  21 other deaths on the original indictment. He is currently serving five consecutive life sentences in an Israeli prison.

We also hear about the immunotherapy that could save cancer patients; and comparisons between the King of Horror, Stephen King and Shakespeare.
