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. Also, we investigate the elegant physics of a lapping cat!
