There is a growing demand in the U.S. military for so-called "biometrics” technologies to identify potential terrorists. In this podcast you will hear about the new ways in which the U.S. military is applying this technology. We also discuss the controversial issue of whether defense contractors should be obligated to disclose incriminating evidence about any potential wrongdoing associated with defense contracts. Finally, we bring you a couple of fascinating science stories. One is a giant “tunnel plug” to stem the spread of fires in subway stations, and the other is a new project to figure out how to recycle spent nuclear fuel.
