On this week's podcast, we find out whether you can blow things up with antimatter. Mark Lancaster, a particle physicist at University College London, comes in to debunk the plot of the new film starring Tom Hanks, Angels & Demons, in which there's an attempt to annihilate the Vatican with the power of anti-matter.
You can probably guess the team's reaction to the film, so why not skip the movie altogether and instead listen to our Cerncast from last year.
We go exploring with the remarkable Catlin Arctic Survey. After more than 70 days of arduous trekking, they've come home having nearly reached the North Pole. We take you through their highs and lows and the science they did on the way.
Plus, we introduce Herschel and Planck - Europe's shiny new space telescopes now orbiting the Earth - we consider whether Obama's climate plan is under threat, and we ask whether vegetarians could save the world.
