Portable Spectroscopy and the Fight Against Food Fraud
Food fraud and adulteration is a serious and increasing problem with significant health and economic impacts. Although robust and sophisticated laboratory methods have been developed to detect fraud, the question of how that experience can be deployed in the field remains. Ideally, handheld instruments operated by nonscientists would be used at a port, in a food distribution center or on a supermarket loading dock. Cases of food fraud — some of which cause serious illness and death

Free-Space Optical Communications Comes of Age
Back in the early 1960s, when first the laser and soon thereafter the semiconductor laser were invented, it was predicted by visionaries that, before long, such sources of coherent light would be used for communication. It actually took more than 25...
