University of Chicago neurobiologist Peggy Mason talks with her Brain Buddies Podcast co-host Aaron Freeman about recent research by Fordham University Ph.D. candidate Matthew Comb. Comb and his team collected scores of rats from different neighborhoods in Manhattan and analyzed their DNA. Their work shows identifiable differences in the SNPs (Single Nucleotide Polymorphisms) of rats in different areas of the island. They hope their findings will help the Mayor DeBlasio et al diminish the big apple’s rodent population.
