• DR.JOE: Carcinogens

    Improperly stored peanuts, corn and certain other grains can become contaminated with molds of the genus Aspergillus flavus. These molds produce aflatoxins which are potent carcinogens. The liver is the most likely organ affected, particularly if it’s function is already compromised by hepatitis B. The story of aflatoxins is an interesting one because they were the first compounds to be recognized as dietary carcinogens. Read More
  • DR. JOE: Herbal remedies

    The beach in the Dominican Republic was sprinkled with vendors of all sorts. They sold delicious peeled oranges, raw oysters and various shlocky souvenirs but the little stand that caught my attention featured a variety of bottles that seemed to be stuffed with leaves and twigs. I went over to look. What are these, I inquired? “Medicine” came the reply. “For what?” “Colds, headaches,…everything.” Read More
  • DR. JOE: Chemical-free

    Today we have “chemical-free” cosmetics, cleaning agents and believe it or not, books about “Chemical-Free Kids.” The message is that chemical-free means safer, healthier, greener.

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?
