    Introducing IDEAS | How a historian found the lost women of science

    IDEAS, hosted by Nahlah Ayed is a weekday podcast that explores how ideas shape our world. “One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists in the ‘70s. Nevertheless, Rossiter persisted. She found and documented hundreds of women whose contributions to science had been overlooked, under-credited and misappropriated. Then she made history herself by coining the term “The Matilda Effect” to describe why those women failed to get the credit they deserved.  Who is Matilda? Matilda Joslyn Gage was a suffragist erased from history. She was known as being too radical for Susan B. Anthony. This episode of IDEAS shares her story.

    Moving beyond animal testing, and more…

    There's been a growing movement to develop new technologies to replace at least some of the animals used in scientific research. Researchers across Canada are working to create these tools, to usher in a new animal-free era for medical science.

    Bonobo females bully the boys, and more…

    We used to think that of our primate relatives, chimps were the more aggressive ape and bonobos were more peaceful. A recent study found that bonobos are just as antagonistic as chimps, but it's the females targeting males.
