One of the tiniest of insects is known for having the deadliest of bites. The malaria-carrying mosquito kills more people than any other animal. Its bite--and the ensuing blood feast--can leave behind lethal parasites in a human host’s system that cause disease. Dr. Chris Potter, professor of neuroscience at the Johns Hopkins University School of Medicine, is studying the insect’s sense of smell. His lab hopes to alter the way mosquitoes perceive human scent and flavor--an effort to make us less appealing as a meal. Want to see what happens when a mosquito stops for a bite? Watch this. To see all that Potter's lab is up to visit his site. Original airdate 6/27/17.
