Meteorite impact leaves rare rocks and evidence of extreme heat at remote lake in Quebec
Meteorite impact leaves rare rocks and evidence of extreme heat at remote lake in Quebec
For more than a decade, Western University planetary geologist Gordon "Oz" Osinski has led expeditions to Kamestastin Lake in Labrador. The environment is a perfect training ground because the properties and rock formations - created by the violent impact (and extreme heat) of an asteroid 36 million years ago - uniquely mimic the surface on the Moon.

Results for: Rural communities face greater risks of radon exposure compared to urban areas
Results for: Rural communities face greater risks of radon exposure compared to urban areas
UCalgary researchers find elevated radon gas levels in rural homes with close proximity to drilled groundwater wells. Henk de Haan built his home southwest of Okotoks, Alta. He was attracted to the wide-open spaces, mountain views, and fresh air. What he didn't count on was radon.  "When we built the home, I didn't know radon was a potential problem.

Saturn's largest moon most likely non-habitable
Saturn’s largest moon most likely non-habitable
A study led by astrobiologist Catherine Neish for Western University shows the subsurface ocean of Titan - the largest moon of Saturn - is most likely a non-habitable environment, meaning any hope of finding life in the icy world is dead in the water. This discovery means it is far less likely that space scientists and astronauts will ever find life in the outer solar system, home to the four 'giant' planets: Jupiter, Saturn, Uranus and Neptune.

Researchers advocate for sustainable logging to safeguard against global flood risks
Researchers advocate for sustainable logging to safeguard against global flood risks
It's time to recognize the power of healthy forests in managing global growing flood risk, and to shift towards more sustainable forestry practices and policy. This call is emphasized by UBC researchers in a peer-reviewed article published recently in the journal Science of the Total Environment . Dr. Younes Alila , a hydrologist and professor in the faculty of forestry, and his graduate student Henry Pham synthesized decades of hydrology studies and found that many "severely and consistently underestimated" the impact of forest cover on flood risk.

More than a meteorite: The new clues about the demise of dinosaurs
McGill researchers challenge current understanding of dinosaur extinction by unearthing link between volcanic eruptions and climate change What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, challenging the traditional narrative that a meteorite alone delivered the final blow to the ancient giants.

New rivers in the North? Scientists identify how the dissection of Arctic landscapes is changing with accelerating climate change
New rivers in the North? Scientists identify how the dissection of Arctic landscapes is changing with accelerating climate change
New research co-led by Simon Fraser University and the University of British Columbia shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years. Documenting a powerful interplay among climate change, the freeze-thaw dynamics of polygonal ground and the delivery of surface water by floods as well as snow and ice melting, the team developed a new view of the physical controls governing the speed and pattern of river channel development in these fragile landscapes.
