Last fall, Dan Carder's cell phone started ringing off the hook. The area codes hailed from major U.S. cities. At the time, Carder was working in his lab at West Virginia University, where he is the director of the Center for Alternative Fuels, Engines and Emissions (CAFEE). Annoyed with phone calls, he finally picked up. The reporter on the line, sensing that Carder had no idea that he had broken international news, advised Carder to Google himself.
