CBC Radio's Quirks and Quarks covers the quirks of the expanding universe to the quarks within a single atom... and everything in between.
From tiny T. rexes to a car-sized sea monster, we revisit some of our favourite stories about predators in their prime, like:
From camping out on 'bird poop island,' chasing down wild dogs in Madagascar, or even looking for bombs in a bog in Ottawa –– no one quite does summer like scientists. This week, we revisit some of the hijinks that Canadian researchers got up to last year as they left their labs to get their hands dirty in the field.
FEATURING:
Quirks & Quarks has been taking your burning science questions for half a century. And while we thought we might have answered every question there is to answer over the years, our listeners proved there are always more fascinating head-scratchers for us to tackle.

Some of the oceans biggest, most powerful predators, like certain sharks and tuna, are “mesothermic” or warm-bodied. Running hot allows them to rapidly convert their food to energy and heat, helping them swim faster and hunt in cold waters. But that advantage may become a disadvantage in a warming climate, meaning these fish need to find new ways of cooling off, or face a new threat to their survival.

Gold miners working in the Yukon regularly find ancient ground squirrel burrows throughout the permafrost, many containing fossilized feces. Researchers analyzing these well-preserved poop piles found they contain some of the oldest DNA ever recovered, dating from 30,000 to 700,000 years ago. Tucked inside were traces of a wide range of ancient animals, including woolly mammoths, grasshoppers, steppe bison, ancient horses, American...
150 years ago, Charles Darwin noticed that birds and humans were both drawn to bright plumage and elaborate display. He called this interspecies esthetic appreciation a “shared taste for the beautiful.” Now, in a recent study, an interdisciplinary team of scientists built an online game exploring the mating calls of 16 different species and discovered, to their surprise, that humans and animals agree on which sounds are...
The newly described Tylosaurus rex was a violent bus-sized Komodo dragon-like creature with serrated teeth. Dubbed the ‘T. rex of the sea,’ it would have occupied the top of the food chain in the marine ecosystem over 80 million years ago.

Scientists recorded audio and video of 8 different kinds of rockfish living in the wild near British Columbia, and were surprised they could tell the species apart through their various grunts, pops and knocks, even though the fish are closely related.

In a study inspired by a field of dandelions, researchers wanted to know why, when you blow on a dandelion seed head, only the seeds closest to you take flight. They found that a dimple in the seed heads where the seed attaches is larger on one side than the other, and that the seeds consistently broke off from the smaller side of that dimple. Once they take flight, each dandelion seed uses its unique shape to catch a ride on the w...
On the morning of August 10, 2025, a landslide in a fjord along the southern Alaskan coast triggered a mega tsunami. It generated the second highest wave ever recorded that reached up to 481 metres above sea level. A new study suggests that catastrophic events like this are more likely to occur as our climate warms and glaciers melt.

Cocaine and many other chemicals and drugs are found in many waterways, but especially around wastewater treatment plants. Scientists exposed wild juvenile Atlantic salmon to cocaine and its byproduct to see how it impacted their behaviour in the wild. As a result, the fish swam twice as far, which could put them in more danger.
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...
Seabird poop plays a surprising role in bringing life to barren islands, spreading nutrients throughout the ocean, and even creating wealth for an ancient human empire.

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:
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.

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.

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.

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.

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.

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.
