A chemistry professor in Spain has invented a robotic tongue that can differentiate between different brands of lager beer. It may have a future in quality control. But will it "sell in Peoria?" - the home of Pabst Blue Ribbon. It won't sell north of the Pyrenees where the French take their wine tasting seriously. To assuage this thirsty tongue a scientist at Cornell has come up with a robot bartender who knows when you're empty and can pour you a refill. But it won't hear your confession after a long day at the office.
