Lab Rats: Genetic Mugshots, Rex Block, and Biden

On our “Lab Rats” science segment, we discuss the effort to develop genetic mugshots based solely on DNA. We also look at the Rex Block, the weather pattern responsible for the late winter storm weather that has been hitting the East Coast. And a new frozen dwarf planet - named 2012 VP113, or “Biden” for short - has been found in the far reaches of our solar system.
