The Artemis mission to the moon is being guided by Kepler, Newton and Einstein
Bob McDonald's blog: Mathematical laws of motion and gravity that go back hundreds of years underpin our ability to guide spacecraft to distant destinations.
A record-setting hailstorm in Alberta was a bonanza for scientific hail chasers
The hail chasers are studying storms closely as climate models suggest there will be fewer hailstorms overall but with larger hailstones when those storms occur

Study takes one small step towards human hibernation for long space flights
Bob McDonald's blog: A new study has given researchers one more reason to think about putting long-duration astronauts in cold storage. It may help protect them against dangerous cosmic radiation.
Q&A
The tall tale of the discovery of the T. rex
In his latest book, David K. Randall takes us back 120 years to the Gilded Age 'bone wars,' when there was a race between American museums to find and display the most impressive dinosaur bones and fossils that they could.

Canada's most prestigious science award goes to research on habitat fragmentation
Carleton University biologist Lenore Fahrig won for her work studying how plants and animals fare when their habitat is broken up into small patches. Surprisingly, she found that preserving many small patches of habitat can work as well or better than trying to preserve a few large chunks.
Analysis
Strong evidence that an ancient ocean once covered Mars
Bob McDonald's blog: It has long been suspected that liquid water once flowed on Mars. Now the latest research shows that billions of years ago, Mars had a deep ocean covering hundreds of thousands of square kilometres.

Bob McDonald looks back at 30 years of hosting Quirks & Quarks
On Oct. 24, 1992 a new voice took the helm at CBC's already venerable science program. Now, three decades and some 7,000 interviews later, Bob McDonald is ready to look back — while still looking forward.

In time for a Halloween tipple? A new book about the science of spirits
Alcohol is intertwined with many aspects of human history and culture — and has been for thousands of years. A new book explores spirits like whisky, vodka, and rum in the context of evolution, ecology, history, primatology, chemistry and molecular biology.

A titanic collision could have formed the moon within hours, new simulation shows
Bob McDonald's blog: Researchers at NASA and in the UK developed the highest resolution simulation of the collision between a hypothetical rogue planet dubbed Theia and a primitive Earth that is the best explanation they have for how the Moon was formed.

Computer simulation recreates the giant tsunami that washed over the dying dinosaurs
Bob McDonald's blog: Researchers have created a computer simulation of the tsunami caused by a giant asteroid impact in the Gulf of Mexico and found it would have created a 1.5 km tall wall of water that decreased in size as it swept around the world.

Q&A
Mi'kmaw astronomer says we should acknowledge we live under Indigenous skies
Mi'kmaw astonomer Dr. Hilding Neilson thinks we should go beyond land acknowledgements and think about sky acknowledgments as well, since we live under Indigenous skies. An astrophysicist at the Memorial University of Newfoundland, Neilson has been working to integrate Indigenous knowledge and methodologies into Astronomy.

James Webb Space Telescope offers spectacular new picture of Neptune's rings — but Voyager got there first
Bob McDonald's blog: Neptune's faint, dark rings are almost impossible to see using Earth-based telescopes. The best view we've had of them was from the 1989 Voyager 2 flyby. Now the James Webb telescope has produced a beautiful new image.
Q&A
A new book lets the Milky Way speak for itself — and it's kind of a jerk
A new book, "The Milky Way: An Autobiography of our Galaxy," by astrophysicist Moiya McTier, imagines our galaxy using its own voice to spill the beans on topics like how it came to be, what it really thinks of us humans, its complicated relationships with other galaxies — and how it will likely meet its demise.
How trash bandits, furry and feathered, outsmart humans for food
In their quest for food, animals venture into human environments to access one of the richest urban food sources: garbage. Two new studies published this month detail how cockatoos and raccoons, two notorious trash bandits, are using their smarts to overcome human obstacles and fill their stomachs.
