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.

Designing a better nest to help endangered turtles
Designing a better nest to help endangered turtles
With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen.

Australian study proves 'humans are planet's most frightening predator'
Australian study proves ’humans are planet’s most frightening predator’
Australia lacks fearsome large carnivores like lions and wolves, and the relative lack of fear that marsupials like kangaroos and wallabies show to dogs (and other introduced carnivores) has been attributed to a lack of evolutionary experience with large mammalian predators.

Western-led analysis shows potential in new Alzheimer’s treatment
Alzheimer's disease is the most common cause of dementia, affecting more than 55 million people worldwide. Currently, the two main approaches for treatments to delay or slow its progression target the buildup of amyloid beta peptides - which form plaques in the spaces between nerve cells in the brain - and the buildup of tau protein, resulting in tangles which damage neurons.

Warm seawater speeding up melting of ’Doomsday Glacier,’ scientists warn
Satellite data provides first evidence of ocean water intrusion beneath Antarctica's Thwaites Glacier  For the first time, there is visible evidence showing that warm seawater is pumping underneath Antarctica's Thwaites Glacier-ominously nicknamed the Doomsday Glacier. An international team of scientists-including a researcher from the University of Waterloo-observed it using satellite imagery and warns that it could accelerate catastrophic sea level rise in 10 to 20 years.

Tour de force: Western Space researchers chart Orion Nebula like never before
Els Peeters, Jan Cami and collaborators among first scientists to use James Webb telescope for research and they targeted star formation Star and planet formation is a messy affair. It starts with the gravitational collapse of a gigantic cloud of gas and dust, which simultaneously produces massive stars, whose intense radiation field creates a harsh environment, as well as more modest stars, like our Sun, surrounded by a planet-forming disk that is rich in organic materials.
