Most lie detector tests monitor a subject's pulse, blood pressure, breathing, and sweat production for signs of emotional upheaval. These conventional methods have been criticised for innacuracies. Jennifer Vendemia, a psychologist at the University of South Carolina, is working to develop a fool proof lie detector test by studying the brain images of people who are lying. She speculates on how her research could be used in practical settings.

Corinna Lathan, cofounder of AnthroTronix, tells Todd about a robot she has developed that could make physical therapy a lot more fun. The "JesterBot" is controlled by remote controls embedding in hats, arm bands, or leg bands. When the child wearing the remote controls moves, so does the robot.

Homer and Marge Simpson may not seem like ideal parents, but Mary Larson, a Communications Professor at Northern Illinois University, tells Todd about a study she conducted of television families that demonstrates that the Simpsons are positive role models in many ways. The study compared and contrasted the parenting methods and sibling interactions of a number of television families.
