    Secularism on trial

    2026/03/19 | 54 mins.
    A case before the Supreme Court of Canada is challenging Quebec’s law on secularism. Legal scholar Benjamin Berger is a prominent voice in the study of constitutional and criminal law in Canada. He argues secularism "is a concept that hides more than it shows." In this podcast, Berger examines how secularism obscures the impact of religion on our legal and political systems. "We end up speaking abstractly about what secularism is, what it demands, instead of whether our government is treating people equally and fairly."

    Benjamin Berger is professor at Osgoode Hall Law School of York University. He delivered Memorial University’s 2026 Henrietta Harvey Distinguished Lecture.

    'There's no such thing as clean energy'

    2026/03/18 | 54 mins.
    If journalist Vince Beiser had his way the term 'clean energy' wouldn't exist — it's a misnomer. He argues green energy comes with cost. Sure, solar power or wind power are both better than power from fossil fuels but Beiser points out they are still harmful to the planet and people. "There's no magic solution." Beiser tells IDEAS we need to shift to renewable energy but we also need to recognize it's not a "magic solution" — there is a downside with consequences.

    Vince Beiser's book is called Power Metal: The Race for the Resources that Will Shape the Future.

    How port cities like Singapore shaped the world

    2026/03/17 | 54 mins.
    Port cities are where worlds collide. They are a place of cultural, economic, political and religious contact. They've existed for millennia and facilitated the birth of empires and the rise of a globalized economy. Without port cities, our world would look very different. In the first episode of our series on how port cities shaped the world as we know it, UBC journalism professor Kamal Al-Solaylee visits Singapore — a constantly-evolving port city whose maritime roots go back to the 13th century.

    She uncovered the lost women of science and made history

    2026/03/16 | 54 mins.
    “One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists. 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 podcast shares her story.

    Guests in this episode:

    Katie Hafner is a former NYT reporter, host and co-executive producer of Lost Women of Science podcast.

    Sophie McNulty is the producer of the Lost Women of Science podcast.

    Ellen Abrams is an assistant professor at the University of Toronto Institute for the History and Philosophy of Science and Technology. She was a graduate student at Cornell University, who shared an office with Margaret Rossiter and was influenced by her work.

    Sally Gregory Kohlstedt is a professor emerita of history of science and technology at the University of Minnesota-Twin Cities, and a close friend and colleague of Margaret Rosstier, fellow science historian.

    Ailsa Holland is a historian and a co-author of On This Day She Putting Women Back into History One Day at a Time.

    Margaret Rossiter (deceased Aug 3, 2025) was the Marie Underhill Noll Professor of History of Science Emerita and Graduate School Professor. She coined “The Matilda Effect” and wrote a three-volume series, Women Scientists in America.

    2026/03/13 | 1h 4 mins.
    Our inherent human rights belong to us from the moment we are born. There is nothing we need to do to earn them, and they are supposed to apply to us until the day we die. But in his third Massey Lecture, Alex Neve argues the powerful have made human rights a ‘club.’ Visit cbc.ca/masseys for more on this lecture series.
