KINGSTON, R.I. (CBS) – Researchers at the University of Rhode Island are testing cutting-edge technology for the TSA. CBS This Morning looked at their efforts to come up with new ways to detect and stop explosives popular with terrorists.

One of the new tech items is called a “digital dog nose” that’s about the size of a cell phone. The sensor can be mounted on a drone and can help Homeland Security detect homemade explosives just as well or better than a bomb-sniffing dog.
