Terrabytes New Investigations (No. 212)

First Aired Thursday, May 10, 2007

This "Terrabytes" episode chronicles three new and exciting scientific investigations. First join Parker Brown in the search for clues behind the increasing number of college smokers. Second, we are hot on the trail with wildlife biologists who are swapping radio collars and GPS transceivers for a more sensitive instrument: a dog's nose. Finally, in Yellowstone's Northern Range, an elusive creature calls this place home and few have what it takes to enter its lair. Join Dr. Toni Ruth in the search for the "Ghosts of the Rockies." Produced by Parker Brown, Eric Bendick, George Potter and Maria Frostic.
