How does nature inspire technology and engineering?  We find out how bamboo may make effective wind turbines and how the protein that enables bees to flap their wings can soothe your bad back. Also this week we explore the explosive backsides of bombardier beetles and how they have inspired powerful fire extinguishers. In the news: how oil lies hidden below the North Pole and why some fatty acids help our immune system more than others. Plus, in Kitchen Science we pop some corn kernels to find out how polystyrene is made.
