Ideas from CBC Radio (Highlights)

As we welcome in the New Year, we eagerly anticipate a fresh roster of IDEAS programs to inspire new ways of looking at our world and understanding it. From the phenomenon of the ‘27 Club'' to exploring literature from Labrador, to social media influencers who push their intellectual pursuits, join host Nahlah Ayed to find out what our producers are cooking up for the 2026 season.

Kritika Vashishtha has been pursuing a cure for jet lag and it's possible she's found the answer. The Canadian aerospace engineer recently invented a variety of light that fools human bodies into switching time zones while aboard an aircraft. She shows two IDEAS producers around her laboratory inside an airplane to explain how the process works. Kritika plans to direct her discoveries towards making space travel easier on astronauts. *This episode is part of our series Ideas from the Trenches, which showcases fascinating new work by Canadian PhD students. It originally aired on April 29, 2024.

If we weren't so used to having books, we would think of them as a "miracle." That's how historian Irene Vallegoviews what she says is humankind's greatest and most influential invention: the book. "With their help, humanity has undergone an extraordinary acceleration of history, development, and progress," she tells host Nahlah Ayed. Vallego has traced written texts back to their earliest origins and she's written a book of her own, Papyrus: The Invention of Books in the Ancient World.

If you think you've never heard Jerry Granelli play drums — you likely have. Think of a comic strip holiday special and an iconic soundtrack: A Charlie Brown Christmas. Jerry was 22 years old when he became a member of the Vince Guaraldi Trio, the jazz band behind the popular 1965 album. His long career was legendary, accompanying many of the greats like Mose Alison, Sly Stone and The Grateful Dead. Producer Mary Lynk was lucky to meet with Jerry on the eve of his 80th birthday for a wide-ranging conversation. The gifted composer and jazz giant died in Halifax in 2021. *This episode originally aired on December 21, 2020.

Handel's Messiah is one of the best-loved pieces of Christmas music. Only it was meant for Easter. But it draws on far more from the Old Testament than the New. There are more surprising facts about this 18th-century masterpiece that IDEAS explores with Ivars Taurins, founding director of the Tafelmusik Chamber Choir who has conducted Messiah over 200 times, and veteran CBC Radio broadcaster Robert Harris. In nine movements, they reveal the hidden treasures of Handel's celebrated work. *This episode originally aired in 2015.

The nativity story that Christians believe is that God took the form of a baby named Jesus who was born to save the world and bring about an enduring peace. So what happened? Did we miss it? And what happens next? These are questions Trappist monk Thomas Merton grappled with in his own meditation on the Christmas story. His version "The Time of The End is the Time of No Room" was published in 1966. At the time he called it a sober statement about the climate of our time, a time of finality and fulfillment.

In an era of political polarization, and fatigue from ongoing crises, education scholar Kari Grain argues hope is vital. It's not something you have, it's something you do. Grain says "critical hope" in action is an abiding belief that transformation is not just possible, but crucial. So how does water play into hope? The author explores how hope can come from three areas: teachers, critical thinking and biomimicry, the practice of observing how nature functions in order to solve human problems. Grain reimagines hope as something that can move like the four habits of water: bending, pooling in deep places, going underground, and persisting. In this way, hope is fluid enough to forge new pathways forward.Kari Grain is a professor at the University of British Columbia in the Faculty of Education, where she leads the Masters program in Adult Learning and Global Change Program. She delivered the University of Prince Edward Island's 2025 Shannon K Murray Lecture on Hope and the Academy.

Indigenous math isn't just about numbers and equations, it involves culture, spirituality and more. Math professor Edward Doolittle, a Mohawk from Six Nations in Ontario, sees math as something embedded in Creation itself. In his Hagey Lecture at the University of Waterloo, he describes Indigenous mathematics as being grounded in cognition, emotion, the physical world and community. Indigenizing math, Doolittle hopes, will make it more approachable and meaningful to Indigenous students — show them how entwined it is with everyday life and something much bigger than ourselves.

"We are the monsters" — that's the premise for the genre of film known as body horror — movies that fixate on monstrous and grotesque changes to the body. There have been good body horror films and bad ones, but "The Fly" starring Jeff Goldblum and Geena Davis was perhaps the most consequential. The movie captured anxieties around bodily autonomy and physical decay, just as the AIDS epidemic was becoming catastrophic. Forty years later, Body Horror is back with films like "The Substance" and "Together." Producer Matthew Lazin-Ryder examines what these films reveal about our bodies, our minds and our sense of who we are.

In 2024, 'polarization' was Merriam-Webster's word of the year. That division still grows, making it increasingly difficult to connect to one another. But there are people having important conversations and they have advice for us all. From fighting for LGBTQ+ rights in Colombia, championing human rights in Southern Africa and working for a two-state solution post Oct. 7, the winners of the The Global Centre for Pluralism awards tell host Nahlah Ayed about how minds can and do change, and why we need to not only talk, but listen.

The yellow traffic light is a perfect example of imperfection — with intention. While driving you have to think fast. Do you speed up or stop, whether that means easily or slamming on the brakes? Every driver has their answer and what lies in the middle is a vast perceptual field. A great deal of thought has gone into the engineering of the ambiguous yellow light, as IDEAS producer Seán Foley found out. He had his own encounter with what he was sure was the shortest yellow light in the world. It resulted in a traffic fine, and gave voice to so many questions.

Tech billionaires are on a mission to make the stories of science fiction a reality: space colonization, human/machine bio organisms, and living forever in a state of unhindered bliss. This version of a far future utopia may come of as a "billionaire boys and their toys" but experts warn such a dismissive attitude is naïve and dangerous. *This episode originally aired on Jan. 22, 2025.

This isn't a wrap or best of 2025 kind of list. This is IDEAS. You deserve more context and information. This podcast offers recommendations that cover several genres and all kinds of topics, to feed your curiosity. Some may surprise you. We asked IDEAS contributors to suggest a work of nonfiction that recently made them think — maybe even think differently — about a particular topic. And then IDEAS producers jumped in to add their picks too.

In fact, author and journalist Marcello Di Cintio argues Canadians are complicit. After four years investigating the lives of migrant workers, he found that many temporary foreign workers are trapped working in precarious, exploitative conditions. These jobs are essential to our economy and society, yet invisible. Each migrant worker has a story to tell, says Di Cintio. He joined IDEAS host Nahlah Ayed on a visit through the tomato capital of Canada to hear their stories and talk about what his investigation reveals about Canada.Marcello Di Cintio's book is called Precarious: The Lives of Migrant Workers.

Growing up with food insecurity, Julian Napoleon yearned to be a farmer. His great-grandparents once farmed on the Saulteau First Nations reserve in northeastern B.C. Over the generations, the farm was replaced by the bush, and the ideas of communal, seasonal living that animated their farm started to fade away. Five years ago, Julian moved to Amisk Farm to bring it back to life. This year the farm has produced food for over 300 Indigenous households, free of cost.IDEAS visits Amisk Farm to learn about rural food security, Indigenous food sovereignty, farming in the north, and what it means to come home and grow a new home in a radically transformed landscape.

There's a constant mantra Frank Gehry would always hear from his mentors who have since died – “Don't you dare ever stop working.” It's a sentiment he lived by right until his death at 96. In fact his last major cultural building, the Guggenheim Abu Dhabi, will open in 2026. So how does his fierce, creative drive square with his mortality?In an expansive conversation from 2017 with IDEAS producer Mary Lynk, Gehry shares his thoughts about death and his life, from growing up Jewish in Toronto, to his complicated relationship with his father, to his move to L.A. at 18, to how his career flourished. *This is the second episode in a two-part series.

Rebel architect Frank Gehry believed architecture IS art. He strived to evoke emotion in every design. Last Friday, Gehry died at 96 but he never stopped creating. In 2017, IDEAS producer Mary Lynk had a rare opportunity to spend two days with Gehry at his LA studio. Their wide-ranging conversation covers many aspects of his life and career, including a moment at 40 when the sight of an ancient piece of art from 500 BC led him to weep. "I think if you went and looked at it, you would cry too," he told Lynk.*This conversation is a two-part series that delves into Frank Gehry's infusion of humanity into his designs.

Sometimes the universe hands us a gift. Over the past year, our podcast listeners spent a total of 526,915 hours listening to our program. That's 21,954.8 days and that translates to 60 years of listening to us. So what better way to mark IDEAS' 60th year then to look back on the highlights and lowlights of the past six decades. To give you a hint on some of the picks, on the bad list: online identity management. Trickle down economics. On the good: Free Trade. Girl Bosses. Apparently open borders is still an open question.Panelists Jamie Liew, a University of Ottawa law professor and novelist; University of Toronto philosopher, Joseph Heath; and the Canadian Shield Institute's, Vass Bednar, joined IDEAS producer Mary Lynk on stage, in front of a live audience at the Isabel Bader Theatre for this episode — the last in our special series celebrating our 60th anniversary.Listen to more episodes:The time when a guest said, "I love you!"How an IDEAS episode on traffic changed a doctor's practiceCBC Massey Lecturers reveal how the talks changed themHow IDEAS saved a listener from sending a regrettable email

"IDEAS is often a surprise" says Cathy Pike. It's why she's been a longtime listener. To our delight, IDEAS was there for her just at the right time. After listening to an episode about Friedrich Nietzche and his philosophy about "the art of passing by," Cathy says she decided not to send an email that she realized she would have regretted. "The program gave me pause and I'm grateful for that.”And we're grateful to hear from Cathy and other listeners who share their personal encounters on how IDEAS shows up for them, as we continue our 60th anniversary series. *This is the fourth episode in our special programming. Listen to other episodes in this series:The time when a guest said, "I love you!"How an IDEAS episode on traffic changed a doctor's practice CBC Massey Lecturers reveal how the talks changed them

This podcast features an all-star, and bestselling, lineup of CBC Massey Lecturers from the past decade: Payam Akhavan (2017) and the police officer who pulled over to the side of the road to keep listening; Sally Armstrong (2019) and the women's rights groups listening to her talks in Afghanistan, Bangladesh and China; Ron Deibert (2020) and his conviction that ‘philosophical' radio is more crucial than ever; Esi Edugyan (2021), Tomson Highway (2022) feeling astonished when a stranger recognizes his voice after hearing him on the radio; Margaret MacMillan (2015); Tanya Talaga (2018) and her surprise when an older white man in the audience declares Indigenous activists should “go forth and conquer”; Astra Taylor (2023) and how her secret desire is to work at IDEAS; Jennifer Welsh (2016) comforting an audience member who'd served in Afghanistan; and Ian Williams (2024) on how his lectures have more meanings than he realized — so much so, that he'd like a “second date” with IDEAS.*This is the third episode in our special programming marking our 60th anniversary.

That's not something you expect to hear in an interview. But the prize-winning author of All That She Carried, Tiya Miles did not hesitate to say these words to IDEAS host, Nahlah Ayed. What prompted the moment was this question Nahlah asked: "You have this term 'liberation theology.' Is your book a kind of liberation history?" Tiya replied: "Oh my goodness, Nahlah. I love you!" And went on to say that her approach to history is all about liberation. Their conversation resonated with many listeners, including a potter in Australia who shares how this story sustains him after the loss of his wife. We also hear from a listening club in Nova Scotia who gather to discuss IDEAS episodes, and we find out how this program inspires everything from sonnets, to art and to recreating historic feasts. *This is the second episode in our 60th anniversary week-long series.

Not many people like to think about traffic but Joanna Oda says this very topic on IDEAS in 2005 inspired her as an ER doctor. "It helped me understand how things that make sense for you as an individual contribute to a collective problem." And she adds, she often finds herself quoting the episode to others: "fixing traffic congestion with bigger roads is like fixing obesity with bigger pants. It might feel better in that moment but we actually haven't solved the root of the problem."This episode is part of a week-long celebration to mark our 60th anniversary. IDEAS is giving the mic to listeners like Oda to share their stories on how our show led to life-altering moments.

For Afghans, listening to a traditional song can bring them back "home." In 2021, when the Taliban seized power again in Afghanistan, orchestras disbanded and musicians fled for their lives. They brought with them their distinctive and storied music, embedded with notes hailing from classical music from Iran and India. IDEAS takes a journey to Afghanistan with members of the Afghan diaspora, and asks how the idea of home is encapsulated in music and how conflict has played a role in reshaping Afghan music.*This is the final episode in a five-part series called The Idea of Home exploring the multiple and contested meanings of home.

In 2022, IDEAS explored how the brutal strategy called "urbicide" — the intentional killing of a city — is used in war to destroy residents' sense of home and belonging. This podcast revisits the original story and includes a brief update from architect Ammar Azzouz. Since the collapse of the Assad regime last year, he has returned to Homs, Syria, twice. He tells IDEAS he has mixed emotions being home again.*This episode is part of our series, The Idea of Home.It originally aired on June 16, 2022.Guests in this podcast:Ammar Azzouz is an architectural critic and analyst at Arup, as well as a research associate at the University of Oxford.

Hospitality — and hospitals. Two words that share a root, but whose meanings often seem at odds with each other. IDEAS traces the historical roots of hospitals, the tension between hospitality and discipline that has defined hospitals throughout their history, and what it means to create a hospitable hospital in the 21st century. *This is the third episode in our series, The Idea of Home, which originally aired on June 15, 2022.People you will hear in this podcast: Rachel Kowalsky is a pediatric emergency physician at New York—Presbyterian Weill Cornell Medicine in New York City.

In ancient Greece, hospitality (or xenia) was seen as a sacred moral imperative. Someone who defied the obligations placed on both host and guest risked the wrath of the gods, or even outright war. Today, the word xenia has largely fallen out of use, but its opposite, xenophobia, has been a driving factor in contemporary politics for years. IDEAS explores ancient traditions of hospitality in this second episode of our five-part series, The Idea of Home. *This episode originally aired on June 14, 2022.

In more than 40 years on the front lines of international human rights Alex Neve has heard Canada described as ‘the land of human rights' — and seen the profound ways Canada has failed to uphold universal human rights, both at home and abroad. In his final Massey Lecture, he lays out his vision for a way forward.

Eleanor Roosevelt once said that universal human rights begin in “small places, close to home — so close and so small that they cannot be seen on any map of the world.” In his fourth Massey Lecture, Alex Neve reflects on moments when people power won the day.*Read this article to learn about the "most powerful" moment in Alex Neve's 40-year-career.

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.

The ideals behind the concept of human rights — such as the sacredness of life, reciprocity, justice and fairness — have millennia-old histories. After the carnage of the Second World War and the Holocaust, these ideas took a new legal form. In his second Massey Lecture, Alex Neve considers six dizzying years that laid out a blueprint for a new world. Visit cbc.ca/masseys for more on the series.

Universality is the core promise of human rights: these rights extend to everyone, everywhere. But above all else, this is where we have failed. In his first CBC Massey Lecture, Alex Neve explores how to ensure the “lifeboat” of human rights is seaworthy for everyone. Visit cbc.ca/masseys for more details about this lecture series.

Whether mechanical or digital, a button delivers the promise of power — but it's far from simple. The small and mighty technology has a riveting history, a story of control, power, freedom and oppression. From the podcast Media Objects, this episode traces the evolution of the button, and asks what happens when every command is reduced to a single press.

When he was eight, 2025 CBC Massey Lecturer Alex Neve watched his mother fight for daycare in Alberta. It's shaped how he thinks about human rights. Ahead of his Massey Lectures next week, Neve shares the pivotal moments in his life that led to his human rights advocacy — and shines a light on the chorus of people he carries with him.

There's history, and then there's oral history. And when it comes to the impacts of war on those who fight them — oral history opens doors to the past that would otherwise stay firmly shut. Michael Petrou, an historian with the Canadian War Museum, argues oral history is especially valuable because it allows us to hear from people "whose voices are quiet, downplayed, or ignored." Their untold stories provide a fuller picture of how war shapes people and societies.

Remembrance Day. Every year we are called on to remember, to reflect on the sacrifices of those who fought in Canada's wars. Veterans of those wars have a conflicted relationship with Remembrance Day: sometimes their own acts of remembrance include official ceremonies, while others avoid them altogether.*This the second and last of a two-part series exploring the post-war experience, gathered by the Canadian War Museum's In Their Own Voices oral history project.

Even when wars end, they go on — transforming the people who fought them, their families, and even society. A former war correspondent interviewed more than 200 veterans of all of Canada's wars for an online oral history project by The Canadian War Museum. The focus is not so much on preserving memories of their combat experiences, but to reflect on what came after. *This is part one of a two-part series.

For someone who died more than 2,400 years ago, Herodotus's voice is still very much alive. "He knows the way [a good story] can elevate but also corrupt and destroy our thinking," says professor Lindsay Mahon Rathnam in this IDEAS episode. The ancient Greek writer observed different cultures first-hand, while capturing the stories they share in an attempt to better understand how they came into being, and why they came into conflict with each other. *This episode originally aired on Oct. 16, 2023.

Political analyst Rachel Maddow and author/activist Rebecca Solnit are sharp observers of Trump 2.0. They both share a common ground: opposition to anti-democratic actions taken by the second administration of U.S. President Trump, and where those actions are taking America, if not the world. The two American writers spoke with Nahlah Ayed about the existential issues of this American moment, a public conversation hosted by the International Festival of Authors and PEN Canada. The onstage event, in front of a Toronto audience, was part of the 5th annual Graeme Gibson Talk in Toronto.

Physics has been full of astonishing discoveries over the past century. But they open up even bigger mysteries that scientists are working feverishly to explain. What is dark energy? And why is the expansion of the universe accelerating? In public talks at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, two prominent physicists – Sarah Shandera of Penn State University and Stanford University's Savas Dimopoulos – discuss the breakthroughs of recent decades and what it will take to solve the most nettlesome mysteries that have deepened in their wake.

The true story of America is that it was built on a caste system comparable to India's, says Pulitzer-prize-winning American journalist Isabel Wilkerson. The author argues that it's key to recognize the roots of the U.S. caste "structure" as she calls it, to understand why conflicts relating to race and class persist. Wilkerson delivered the 2025 Beatty Lecture at McGill University in Montreal.

There's a burgeoning genre of fiction coming from Mexico — stories that merge socio-political history and the impact of drug-related violence with fantastical stories of eerie ghosts, zombies, and monstrous cannibals. IDEAS explores dozens of gothic, horror and crime fiction novels. *This episode is part of our ongoing series, IDEAS from the Trenches, about outstanding PhD scholars across the country. It originally aired on June 5, 2023.We'd love to hear from you. Fill out our listener survey here.
