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.
