The article Truth, lies differ in brain scans is from CNN

“WASHINGTON (Reuters) — Brain scans show that the brains of people who are lying look very different from those of people who are telling the truth, U.S. researchers said on Monday.”

Accurate lie-detection offers concrete judgment of honest, which then helps us establish trust.
The success by brain scan is partial based on that it is hard for lier to control the brain activity. The other well-known lie-detection signals, such as gesture, voice, heart rate are much easy to observe but also easy to be pretended. I’m look forward to see more concrete proof of such discovery.
