About The Show

The “Dr. Joe Show” is the longest running “call-in” radio program on science in Canadian history. Joe Schwarcz, Professor of Chemistry at McGill University in Montreal and director of the McGill University Office for Science and Society, began answering questions from listeners way back in 1980. Where does aspirin come from? What is genetic modification all about? Should we be concerned about “endocrine disruptors” in cosmetics? Can peppermint oil help with digestive problems? Questions such as these crop up with great regularity in people’s minds and Dr. Joe helps unravel the confusion with his easy-to-understand explanations. There are also interviews galore with leading scientists from around the world.

Dr. Joe has answers to your questions about the science of everyday life, and each week also entertains and informs listeners with a multitude of stories drawn from the world of science. You never know what is going to come up. Will it be a query about removing the mustache painted on a Barbie doll by a mischievous youngster, or a criticism of an inaccurate press report about the beneficial effects of chocolate?

Talk to the man behind the lab-coat Sundays at 3:00 on Montrteal’s News Talk Radio, CJAD 800.

  • DR. JOE: Oral bacteria and heart disease

    The mouth is sort of a gateway to the body. In periodontal disease pockets inhabited by bacteria form where the teeth meet the gums. The problem is that bacteria can escape from these pockets directly into the bloodstream. Read More
  • DR. JOE: Science and Answers

    Science doesn’t have all the answers. And no scientist claims that it does. Of course it depends on what the question is. If the question is what it takes to put a satellite into orbit, we can answer it with absolute certainty because it’s been done. The evidence is clear. We wouldn’t be watching satellite TV if we didn’t know how to launch a satellite. If the question is about making stainless steel, or tires, or aspirin or lightbulbs or hockey pucks, we have the answers because these things exist. Read More
