SCIENCE STUDIO: The Science of Odor
Keith talks with Anandasankar Ray, Professor of Entomology at the University of California, Riverside. Ananda talks about how odor molecules attach themselves to receptors in our noses, and why the structure of those molecules is so important in our perception of smell. We'll also hear about the talents of female mosquitos in seeking out prey. They are attracted to the carbon dioxide in our exhalations, and they can track us from several meters away. Ananda also explains why some of us are tastier to mosquitoes than others. http://olfaction.ucr.edu/
