This week, James Randerson is joined by brain and cognition scientist Dr Martin Monti to discuss the computerised mind-reading technique that, one day, raises the possibility of being able to visualise a person's thoughts or even their dreams.
Also in the show, we hear from John Beddington - the UK government's new chief scientific advisor - and his thoughts on populations and biofuels. Are they really more important and more urgent than climate change?
Plus, we're at ESA's latest launch, hear exclusively from Sweden's only astronaunt - and shoot down in flames the crisp company that's hoping to advertise in space.
