[00:23.71]when someone lies you get an instantaneous
[00:26.32]warming around the eyes...
[00:28.05]commonly known as "blushing".
[00:29.83]Dr James Levine of the Mayo Clinic
[00:32.39]in Rochester, Minnesota,
[00:34.34]speculates that people who lie are afraid
[00:36.72]of getting caught.
[00:38.29]"That fear triggers a primitive response

[00:44.60]can more efficiently map out an escape route,"
[00:47.49]he says.A high-definition,heat-sensing camera
[00:51.39]can detect such blushes;
[00:53.58]the new technology has proved more reliable
[00:55.87]than conventional lie detectors
[00:58.03]and could offer a new tool
[01:00.01]for mass security screening at places
[01:02.44]like airports,office buildings
[01:04.43]and high-profile events.
