NASA's Crew-11 started a return journey to Earth on Wednesday, cutting short their six-month stint in space after an unknown crew member suffered an undisclosed medical condition.

Most of us abandon New Year's resolutions within four months. But experts say it doesn’t have to be that way — and if you want to make your good intentions stick, there are ways to use science to work in your favour.

Atmospheric rivers — and the flooding they bring — are intensifying with climate change. For the past decade, the same hurricane hunter planes used to study cyclones have been flying straight into these West Coast rain-makers. Why? Because the data they collect proves these flights can significantly improve forecasts. CBC’s Johanna Wagstaffe looks at how that evidence is driving a major expansion of the program.

An iceberg that was once the biggest on the planet is floating off into the South Atlantic Ocean, where it will soon melt away into watery oblivion. But it's going out in style.

An earthquake which struck near the Alaska-Yukon border last month has revealed a fault line hidden beneath ice, drawing international research interest.

A black bear cub caught in a fire this past December continues to make a recovery in Smithers, B.C. Rescuers said the bear was burnt while hibernating in a slash pile set on fire near Dawson Creek, B.C.

The pots were created using a mix of wild and commercial clay, and were placed in the waters of Cranberry Cove in December.

Lucky 7 Cattle Co., near Sedgewick, Alta., started 2026 with a bang, welcoming a set of healthy triplet calves — for the second year in a row.

Moscow used its hypersonic 'Oreshnik 'missile to target critical infrastructure near Lviv in western Ukraine. Its use of the missile is being seen as more about political messaging, than battlefield strategy.

Eutelsat, a company largely owned by the French and U.K. governments, is offering Canada an alternative to Elon Musk's Starlink satellite broadband communications in the Far North. The company says it can create secure channels that cannot be disconnected for "political" reasons.

To better understand the complex interactions between nature’s hunters and hunted, researchers gathered at the the Éco-Laurentides park near Val-Morin, Que., for a game of predator-prey.

NASA is cutting short a mission aboard the International Space Station after an astronaut had a medical issue.

"We have to understand that it's not a question of if the glaciers are going to disappear, they are going to disappear," warns Brian Menounos, a professor of earth sciences at the University of Northern British Columbia

The internet loves a cat video - and a wildlife encounter captured on film in northwestern Ontario this January is no exception. The footage features a group of lynx, including three kittens.

A mountain gorilla has given birth to twins in war-ravaged eastern Congo, a national park announced on Wednesday, in what it described as "a major event" for the endangered subspecies.

A spider with extraordinary genitalia, a carnivorous caterpillar that wears its prey's body parts, and a tiny opossum are among the cool new species described by science in 2025.

Pilots can’t see it coming, and it’s hard to avoid. But severe clear-air turbulence can shake a plane ‘like King Kong.’ It’s on the rise, and forecast to get worse due to climate change. The rise has researchers investigating how to better predict clear-air turbulence, and looking to the physics of birds to make this chaotic force less dangerous.

A team of international researchers, led by a University of British Columbia astrophysicist, has discovered a young galaxy cluster that was producing hot gas at a rate five times hotter than previously theoretically thought possible.

In one of the most important meteorological events in the province’s history, successive bouts of freezing rain left thick layers of ice over everything in southern Quebec during a week-long span in January 1998, knocking out power for millions of people.

A pod of orcas surprised people on B.C.'s Sunshine Coast earlier this month by swimming close to shore and rubbing their bellies on the rocks — a behaviour an expert says few killer whales around the world have been observed doing.
