Dust? Tongues? Uranus? It’s our Holiday Question Show!

On this week’s episode of Quirks & Quarks, it's our ever-popular and always satisfying Holiday Listener Question Show that includes: Why did a Canadian astronaut's eyesight change when she went to space? How is the dust inside our homes changing? Why do some professional athletes stick out their tongues when they play? Why are most fruits round, but bananas and pineapple are not? What would have happened if the dino-killing asteroid never struck Earth? We'll satisfy all these scientific curiosities and many more!

A 25-year-old time capsule with science predictions for 2025

Twenty-five years ago, Quirks & Quarks celebrated their 25th anniversary by travelling forward in time — to 2025 — to find out how science had changed in the years since. In this fictitious future, our present, Zargon the robot, wakes up a Bob McDonald clone from the year 2000 to speak with scientists about 25 years of science. It's a mindbending audio time-capsule with predictions that were oddly prescient, sometimes unsettling or wildly wrong.

How the invention of the book shaped humanity

If we weren't so used to having books, we would think of them as a "miracle." That's how historian Irene Vallego views 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.

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.

Jazz fan or not, you've probably heard this musician play

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.

An apocalyptic retelling of the Christmas story

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.

Revealing facts about the Christmas song meant for Easter

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.
