A "bulletproof" lie detector could be on the way.
Steve Rock reports in today's Star that there's a St. Louis native developing said failproof test. By using (ready for your psychology lesson of the day?) functional magnetic resonance imaging --- or fMRI --- scientists are able to measure neurological activity in your brain. Specific areas of the brain are activated when people lie, and fMRI, essentially, can make them light up, the guy says.
Obviously, such technology would change the world of crime prosecution forever. BUT (you knew it was coming) even if the test proves successful, it'll likely be years before the research is sufficient to support it.
