Answering all your burning science, technology and medicine questions this week are Dr Chris, Dr Dave and Dr Phil, who look at why purifying seawater won't solve our water shortage problems, how 3D glasses work and whether a man on a meteor would have to hold on tight or sit back and soak up the stellar scenery. We'll also be receiving an update from Daniel Scuka at the European Space Agency on the Venus Express Mission, Professor Diana Liverman from Oxford University talks about how to turn down the heat on climate change, and in Kitchen Science Anna Lacey finds out why we hear strange voices when we play old records backwards...
