Wrestling 14-foot 'dinosaurs' to figure out why they're dying

Dr. Madison Earhart, a postdoctoral fellow from the University of British Columbia, spent her summer fishing for enormous white sturgeon in the Fraser and Nechako Rivers in British Columbia. Since 2022, there have been a large number of deaths of this fish along the west coast of North America and it’s concerning when a species that’s been around for hundreds of million years suddenly starts dying off. She and her colleagues are trying to figure out what’s happening and how to conserve this important and spectacular fish.

Installing Dark Matter detectors two kilometeres underground

Dr. Madeleine Zurowski of the University of Toronto has been underground most of this past summer at SNOLAB, located in Sudbury, Ontario. She’s been helping install specially designed dark matter detectors in a project called SuperCDMS, as part of an international collaboration that is researching the nature of dark matter.

Managing Canada’s worst invasive plant with moths

As Director of the Waterloo Wetland Laboratory, Dr. Rebecca Rooney has been investigating how to stop the spread of a plant called invasive Phragmites, which chokes wetlands, ditches and many other environments. Her group has introduced European moths which eat the plant. This summer PhD student Claire Schon and lab technician Ryan Graham went into the field to collect some more data on their project.

Helicoptering in 35 tonnes of material in an attempt to restore a Sudbury peatland

Scientists are working to restore a degraded peatland damaged by contamination from mining activity in Sudbury. Colin McCarter, the project lead from Nipissing University, described how they’re trying to figure out how to best restore these toxic metal-contaminated landscapes to restore their natural capacity as wildfire-buffering, carbon-storing powerhoues.

Transatlantic balloon flight from Sweden to Nunavut

Dr Kaley Walker is an atmospheric physicist from the University of Toronto. Working with the Canadian Space Agency, this summer she was in Sweden to send a massive balloon — 30 stories tall and 800,000 cubic meters in volume — on a high-altitude transatlantic flight to Nunavut, to measure stratospheric gases.

The accidental discovery of an ancient Roman monument’s missing limb

Dr. Sarah Murray is the co-director of an archeological project on the history of Porto Rafti, Greece. While surveying for Bronze Age relics, her team discovered an enormous missing limb from a famous Roman marble statue in the area, a monument popular with tourists for centuries. This summer, they returned with drones to make 3D models of the statue, to understand how the arm was attached to the statue’s now limbless torso.

Canadian astronaut Jeremy Hansen gets lunar geology training in Iceland

Astronauts assigned to NASA’s Artemis II mission, who’ll be heading to the moon as early as September 2025, embarked on their own field research this summer in Iceland to train as lunar geologists. CSA astronaut Jeremy Hansen documented his adventure and filled us in on why this training is crucial for their upcoming mission.

Building wildfire resistant housing

After wildfires devastated Lytton, BC in 2021, the government announced that they were going to support homeowners to rebuild homes that would be resistant to wildfire. Senior Engineer Lucas Coletta of Natural Resources Canada, was part of the team that tested various fire resilient materials and construction methods this past spring and summer.

A behind-the-scenes chat about the making of the CBC Radio collaboration called "Overheated." White Coat, Black Art, What on Earth, and Quirks and Quarks are exploring how heat is affecting our health, our communities and our ecosystems. This originally broadcast on The Current.

Quirks & Quarks launches our new season with a special on urban heat. It's part of a collaboration with White Coat, Black Art and What on Earth called "Overheated."

Host Bob McDonald and Producer Amanda Buckiewicz tell the story of how a city’s design can influence the way we experience and cope with heat. Bob will cycle through the streets of Montreal with a Concordia researcher on specially-equipped bikes - these are equipped with sensors that measure how temperatures change across neighbourhoods based on their density - the amount of infrastructure coupled with mitigating cooling effects like tree cover.

He’ll also spend time with a McGill epidemiologist who will deploy hundreds of sensors that measure air temperature every 30 minutes over a month. That data will be used to determine how changing temperatures impact physical and mental health. It's vital information as heat is thought to be the most lethal kind of extreme weather.

And we'll explore some of the solutions to urban heat: How we can design buildings and urban landscapes - with a little help from nature - can make our cities cooler and more comfortable as the temperature rises.
