Our Halloween Special of Western Science Speaks includes Western University researchers Dr. Liana Zanette, Dr. Yolanda Hedberg, and Dr. Lyle Muller. Our guests join the show to talk about how fear evolved, varies across species, and how it stays with us. We also reveal the chemistry of candy and everything you need to know before biting into your Halloween haul. Don't be scared, tune in to hear fright night explained!
