Steve Caplin discusses a Japanese theft detection system for shops that is wrong one time in five and the Chinese response to "epidemic" toilet paper theft. Also the computer game that takes place over 8 million years, the world's first 3D-printed heart, Google's trial drone delivery service, steam trains running from Waterloo again and a crowd-funded LCD "window" that displays whatever view you would like.
