Quirks and Quarks

IDEAS, hosted by Nahlah Ayed is a weekday podcast that explores how ideas shape our world. “One of your tribe is enough.” That’s what Margaret Rossiter was told when she said she wanted to study female scientists in the ‘70s. Nevertheless, Rossiter persisted. She found and documented hundreds of women whose contributions to science had been overlooked, under-credited and misappropriated. Then she made history herself by coining the term “The Matilda Effect” to describe why those women failed to get the credit they deserved. Who is Matilda? Matilda Joslyn Gage was a suffragist erased from history. She was known as being too radical for Susan B. Anthony. This episode of IDEAS shares her story.

Several recent studies are shedding new light on the surprising role that seabird poop plays in bringing life to barren islands and creating wealth in a burgeoning kingdom. PLUS:

We tend to think of animals like snakes, rats and even cockroaches as pests, but in her new book, biologist Marlene Zuk says there's a lot we can learn from these less than desirable creatures, if we just give them a chance. PLUS: A case of mistaken identity: The truth about the world's 'oldest' octopus fossil From the archives: Carl Sagan on the worlds beyond our solar system The evolutionary cost of our relationship with fire We're not speaking as much as we used to — and scientists are concerned

There's been a growing movement to develop new technologies to replace at least some of the animals used in scientific research. Researchers across Canada are working to create these tools, to usher in a new animal-free era for medical science. PLUS:

On their mission around the moon, Jeremy Hansen and his crewmates will become the only four people on Earth to ever lay eyes on the entire far side of the moon. Since joining the space program, the Artemis astronauts have been undergoing intensive geological training to help train their eyes to look for lunar features that satellites can't pick up. PLUS:

New research confirms that dogs were the first animal to form a domestic relationship with humans, dating back to the end of the last Ice Age almost 16,000 years ago. PLUS:

An unusual hellscape of a planet found 34 light years from Earth has a deep ocean of molten magma surrounded by noxious, hot, rotten egg-type fumes. It just may be the most uninhabitable alien landscape we've ever come across. PLUS:

We used to think that of our primate relatives, chimps were the more aggressive ape and bonobos were more peaceful. A recent study found that bonobos are just as antagonistic as chimps, but it's the females targeting males. PLUS:

You may have seen Black Hole, the image, but have you heard of the upcoming Black Hole, The Movie? This week, astronomers launched a new campaign to capture video footage of the supermassive black hole pulsing at the heart of the M87 galaxy. PLUS:

Starfish don't have brains, and yet they're able to mobilize hundreds of tiny hydraulic tube feet to get around. Now scientists are getting an understanding of just how they do that. PLUS:

From the pressurized space suits to living in underground spaces, it's clear that living on Mars would cause irreversible biological changes to any humans living there, to the point that it may be impossible for them or their descendants to return to Earth. With bigger heads and lighter bodies, might we also end up looking like Martians? PLUS:

An elephant’s trunk is incredibly strong and rugged, and yet it is one of the most sensitive touch organs in the animal kingdom. New research reveals that this sensitivity is partly powered by over 1000 whiskers. PLUS:

Researchers made the surprising discovery that Alaska beluga whales have swinging sex lives — and that could be their key to survival in the warming Arctic. Plus:

Scientists spent nearly 25 years studying close to 800 polar bears in the Barents Sea region and discovered that those polar bears seem to be doing just fine, even though melting sea ice is also a major issue. PLUS:

Some dogs are more adept at learning language than others. Researchers studying these special dogs discovered that, much like toddlers, these smart furry canine companions can pick up words just by eavesdropping on their owners' conversations. PLUS

We may share a common ancestor with chimpanzees, but somewhere along the evolutionary line to us, our brains took a major detour. New research suggests that chimpanzees can rationally weigh evidence, a trait that used to be thought as uniquely human. PLUS:

An unassuming fossilized slab in the basement of a museum in Brazil turned out to be 110-million-year-old dinosaur vomit, and inside that vomit were the bones of two strange, seagull-sized pterosaurs. PLUS:

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!

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.

We talk to authors of some of this year’s most fascinating science books in our annual Holiday Book Show. INCLUDING:
