How Indigenous Americans discovered Europe

Indigenous Americans on European soil can be found throughout historical records, but historian Caroline Dodds Pennock says they have largely been ignored.

The author told IDEAS host Nahlah Ayed about her research collecting evidence of the widespread Indigenous presence in Portugal, Spain, France, and England in the 100 years before Britain attempted to establish its first North American colony. *This episode originally aired on April 5, 2023.

Falen’s new show! Introducing: See You in Court

The stories behind the legal battles that changed Canada — and the unlikely people who made it happen. Some were sh*t disturbers, some were convicts, and some were just regular folks dragged into a fight. Each week, host Falen Johnson teams up with a journalist to dig into a case that challenged the status quo, and asks: what kind of person takes on the law? What are the costs? And what would our lives look like if these cases never happened? Because let's be real, just because a case is closed doesn't mean the story’s over. More episodes of See You in Court are available here: https://link.mgln.ai/syic-sloc

The mystery of the drunken trees, and more…

This week: bees trained to keep track of time, eating small amounts of plastic can kill ocean animals, scientists spot winds blowing from our black hole, a "one-two punch" earthquake may be coming for the Pacific coast and what “drunken trees” can tell us about our warming climate.

The best — and worst — ideas of the last six decades

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.

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.

Are critical minerals over-hyped?

A lot of people are calling critical minerals a major opportunity for Canada, but we explain why their real benefit may be more strategic than economic.

Buttons give the illusion of power but hide the consequences

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.
