Steve Caplin, Share Radio's technology editor, asks if scientists in Antarctica have found a parallel universe where time runs backwards. He looks at the robot dog now on sale as well as Lego's Super Mario enabling you to play a "real" game. He turns up his nose at an Age of Odour exhibition about smells and discusses the world's biggest liquid air battery, how you can eavesdrop with a lightbulb, 3D print within the human body, put out fires with a vase and stop legged robots slipping up.
