Artificial Intelligence Helps Sniff Out Suspected Secret Nuclear Weapons Programs

Scientists with the complicated task of tracking secret nuclear weapons developments around the world are getting some help from a new and more-advanced artificial intelligence system. Nuclear explosions, even underground ones on the other side of the world, leave signature traces of radioactive gasses. This system helps sort through masses of data to find which radioactive traces are relevant and which are naturally occurring, which are new and which are left-overs. Faith Lapidus reports.
