12-28-10: Oh Rats!
Conversation originally aired June 16, 2009.
Charm City’s charm stops at its rat populations. But Johns Hopkins University Professor Greg Glass is entranced by the nibbling nightmares. By studying DNA similarities found in rat populations across the city, he’s learned how they move and–more important for humans–how they might spread disease. Professor Glass talks with Nathan Sterner about what he’s discovered and some of his more colorful encounters with our rodent neighbors.
