On the Science channel show Weird Connections, the "Lying" episode had several interesting segments. One segment involved an experiment where micro expressions were being evaluated by experts to determine whether the participants were lying or not. Another, based on the work from the previous segment, was the same concept but with the micro expressions being examined by computer (sure to end up in an airport near you). Also discussed was the use of thermal imaging of the face as a detection method and  the use of micro expressions for passenger profiling in airports. Altogether an episode worth watching.
