Forests have a special magic for many of us. Steeped in folklore and fantasy, they are places for enchantments, mythical creatures and outlaws. But if they are to survive into the future, they may also need a helping hand from science.

Food fraud, where different or low-quality food is deliberately mislabelled and sold as high-quality goods, risks the health of consumers as well as the economic viability of producers and manufacturers. To combat this, researchers have figured out that analysing the past and present behaviour of criminal activity could predict what they might target in the future.
