Smart Pills: Drugs to Boost Brain Power
IQ-elevating agents that can boost brain power are being used by over 10% of university students. But how do these cognitive-equivalents of anabolic steroids for the brain actually work, what are their effects and are they safe? Moreover, is the advantage they confer an ethical one? And if not, should universities be screening students ahead of exams to deter their use? Meanwhile, in the news this week, we find out how lasers can cut complications in cataract surgery, why some people are allergic to wine, we hook up with the highlights from the world's biggest neuroscience meeting including...

We set sail to discover the science of sustainable shipping in this week's Naked Scientists. We visit an enormous wave tank to find out how the sea swell can impact on damaged ships, and look at the problems caused by sulphur-rich shipping fuel. Plus, we hoist the SkySail, an enormous parafoil kite that can be deployed from the deck of a ship to cut fuel consumption by up to 60%. In the news we hear how happiness can be found here and now, why children tire so quickly when walking and how Earth became oxygenated 400,000 years earlier than we thought.

Cancer - Hallmarks and Hit and Run Viruses
We catch up with cancer research this week including evidence that cancers subvert stem cells to suppress the immune system and how covert "hit and run" viral infections may be triggering a lot more tumours than we first thought. Also, joining us from the National Cancer Research Institute conference in Liverpool, cancer biologist Bob Weinberg explains how he sees cancer becoming a controllable chronic condition within just ten years. Plus, the buzz around a new tumour-spotting ultrasound technique, how a burst of electricity to the brain boosts mathematical ability, a new trick to block the... Like this podcast?
