Please Explain: Prions

On today’s Please Explain we're looking at prions and how they can cause infectious diseases such as Mad Cow disease and the Chronic Wasting disease that’s been affecting deer, elk, and moose herds in the West and Midwest. Dr. David Westaway, Professor of Neurology and Director of the Centre for Prions and Protein Folding Diseases at the University of Alberta; and Walker Jackson, postdoctoral associate in the Lindquist Laboratory at MIT's Whitehead Institute for Biomedical Research join us.
