T-Rex Autopsies, Autism & Venomous Snakes on Friday's Access Utah

For the first time scientists have dissected, from skin to blood and bones, a life-like Tyrannosaurus Rex dinosaur.  The massive creature was one of the fiercest carnivores in the history of the planet.  On Friday's AU, Sheri Quinn talks with the paleontologist leading the T. rex Autopsy, which is featured on the National Geographic Channel Sunday night.
Then, Science Questions explores new studies on autism presented at the International Meeting on Autism Research held in Salt Lake City in May.
