    How port cities like Alexandria shaped the world

    The city of Alexandria has been the source of invention, innovation, and beauty for millennia. It captured the imagination of many people such as Napoleon, St. Mark the Evangelist and the Prophet Muhammad. Alexander Great had a vision for his namesake city — a place of cultural, intellectual, economic, political and religious exchange. IDEAS examines the many ways this port city shaped the world we live in. Part three in our ongoing series about how port cities shaped the world as we know it.

    The real reasons why more young women freeze their eggs

    2026-05-26 | 54 mins.
    Egg freezing is considered a kind of "fertility insurance" for the future — a way to buy more time to make a decision about having a family. However, as IDEAS contributor Alison Motluk discovers, uncertainty around parenthood is just one of many reasons why egg freezing is one of the fastest-growing reproductive technologies in the world. She explores those reasons and digs into the social politics, gender realities, and big business of egg freezing.*This episode originally aired Oct. 22, 2025.

    What does it mean for a river to be ‘alive’?

    2026-05-25 | 58 mins.
    Renowned natural history writer Robert Macfarlane traveled to Ecuador, India and Quebec, pondering the question of whether rivers are living beings — the premise behind much of the movement to legally recognize the rights of nature. He found that the answer to that question is more complicated and wondrous — and more life-altering and world-changing — than he could have imagined. *This episode originally aired on Sept. 3, 2025.

    Why there's no place like Oz

    2026-05-22 | 54 mins.
    Even if you aren't a fan of Frank L. Baum's The Wonderful Wizard of Oz, you know about the Tin man, the ruby red shoes and that the dog is named Toto. The classic story was an instant bestseller in 1900 and its popularity is still going strong with not one but a two-part prequel. For over 125 years, there have been derivative works of Oz, from Broadway musicals, films, comic books and more. IDEAS follows the proverbial yellow brick road to uncover how this seemingly simple story of friendship, self reliance and longing for home continues to speak to us. *This episode originally aired on Sept. 9, 2025.

    If this episode has left you curious about Matilda Joslyn Gage, the suffragist who was a big influence on Frank L. Baum's feminism, listen to this podcast. There's a reason you likely have never heard of her.
