We're not machines. Why should our online world define life?

We gorge ourselves on the internet, smartphones, social media, information overload — all of it constantly sap us of our emotional and intellectual vitality. Authors Pico Iyer and Jonathan Haidt argue it's vital we disconnect from our addictive online world to pursue a fulfilling, and richer life. By curtailing the noise of technology, media and other worldly distractions there's space to reconnect with the things that matter. "Humans were never designed to live at a pace determined by machines. The only way we could begin to do that is by becoming machines ourselves," says Iyer. Pico Iyer and Jonathan Haidt were two of the marquee speakers at the 2025 Aspen Ideas Festival. The theme this year was 'What Makes Life Good.'

What makes left-handers special?

This podcast seeks answers to the question. If you are left-handed then you are part of the 10 per cent of humankind that detested craft time in elementary school that involved scissors. Left-handed people often have to accommodate their difference in our dominant right-handed world. But that can get tricky if you are training to be a surgeon. Operating rooms and surgical instruments become big obstacles for left-handed people as IDEAS contributor Mark Dance finds out in his documentary exploring the history and mystery of left-handers. *This episode originally aired on May 6, 2022.

A lesson on why NOT to engage in polarized discussions

The great divide in politics is all around us. Sometimes the best way to engage in a difference of opinion is to 'pass it by.' Political theorist Shalini Satkunanandan suggests we take that lesson from Friedrich Nietzsche's philosophy. Yeah, that guy — the one most known for his wrestling with nihilism. Satkunanandan argues that the constant need to engage and correct, refute or criticize "is making partisan divides even more pronounced." She views Nietzsche's method as a valuable way to navigate the highly polarized discourse of today. *This episode originally aired on Jan. 20, 2025.

Where did modern news culture come from? Think Shakespeare

It might seem like the vast, turbulent ocean of information we call news has always existed, but that's not the case. Theatrical plays in Elizabethan England set the stage for our modern news culture, argues Stephen Wittek in his post-doctoral work. He says the cross-pollination between theatre and news developed the norms for our contemporary public conversations. *This updated episode of Ideas from the Trenches was originally broadcast in 2014.

Can you have compassion for someone you never agree with?

Ask yourself: can you? It is a question that George Eliot asks over and over through her characters in Middlemarch, a 19th-century novel that speaks to our own fractious age. Eliot highlights how important it is to see the world from the point of view of others — even characters we don’t like. *This is second episode in our two-part series. It originally aired on April 7, 2002. We'd love to hear from you! Complete our listener survey here.

How Jeremy Hansen is prepping for the moon, and more…

Next stop - the moon! Jeremy Hansen stops by our studio to chat about how he’s prepping to be the first Canadian to go to the moon. Plus: Santa’s reindeer may be losing their antlers –– and climate change could be the culprit Reindeer are the only animal in the deer family where the females also grow antlers, and they typically have a full rack over the wintertime and drop them in June when they give birth. University of Guelph PhD student Allegra Love was monitoring reindeer on Fogo Island in Newfoundland, when she made a surprising discovery that female reindeer are losing and growing their antlers much earlier than usual. This can put more stress on the animal during a crucial part of their pregnancy, and the researchers think this could eventually lead to the reindeer losing their antlers altogether. The work was published in the journal Ecosphere. Pterosaur brains reveal clues about why these mighty fliers took to the skies Flight has only evolved among vertebrates three times — in bats, birds, and first in pterosaurs. How pterosaurs first took to the skies was always a mystery to scientists, until the discovery of a fossilized 230-million year old pterosaur relative in Brazil. An international team, including Ohio University professor Lawrence Witmer, used an MRI for detailed analysis of the fossilized skull, to pinpoint the miniscule brain changes that happened as the animal developed the capacity to fly. The research was published in the journal Current Biology. Scientists are using AI to find life in 3 billion year old rocks Earth’s earliest signs of life are often incredibly difficult to detect. An international team of researchers have developed a new tool that uses AI to find “whispers” of life locked inside ancient rocks. Using this tool, the researchers, including astrobiologist Michael Wong from Carnegie Science, were able to detect fresh chemical evidence of life in rocks that are 3.3 billion years old. This tool can not only be used to explore the origins of life here on Earth, but also on Mars and other planetary bodies. The work was published in the journal PNAS.
