Mission to Thwaites glacier ends in disappointment and forces a strategy rethink
Quirks and Quarks13:00Mission to Thwaites glacier ends in disappointment and forces a strategy rethink
Western Antarctica’s Thwaites glacier is known as the “doomsday glacier” due the precarious position it’s in as climate change continues to warm the ocean, melting the glacier from beneath. The collapse of this glacier would raise sea levels by a half a metre. In their most recent visit, David Holland of New York University said they were disappointed after instruments they were attempting to install under the glacier by drilling through it with hot water got stuck. Now it’s back to square one for the scientists to figure out how to get that critical data.

Quirks and Quarks10:59Near-infrared light therapy offers hope to football players with brain injuries
Football players can suffer serious injuries from their time on the field, including concussions and even Chronic Traumatic Encephalopathy, a debilitating neurological disorder. Larry Carr, a former CFL player who played for the Calgary Stampeders in the 1970s, saw his quality of life disintegrate after many years of taking blows to the head playing football. He saw great improvements with near-infrared light therapy, which inspired him to approach a research team in Utah to further study how well it works with a test group of American football players. Hannah Lindsey led this study and found it dramatically reduced and prevented inflammation in the brain over the course of a season. Their research is published in the Journal of Neurotrauma.

Quirks and Quarks8:30Why Alaska beluga whales have swinging sex lives
Researchers trying to understand how social species are adapting to a changing Arctic made the surprising discovery that in one pod in Alaska, belugas frequently switch mates. Working with Indigenous hunters, scientists including Florida Atlantic University’s Greg O’Corry-Crowe analyzed the DNA of hundreds of whales in the remote region, revealing how both males and females mate with multiple partners over their lifespan. The scientists believe this is helping the belugas preserve genetic diversity in their small population. The results were published in the journal Frontiers in Marine Science.

Scientists teamed up with Indigenous hunters in Alaska to collect skin samples in order to analyze their DNA. (Joshua A.

Quirks and Quarks19:09The new Atomic Age: with nuclear power making a comeback, what’s changed?
Nuclear power has been steadily providing power in Ontario and New Brunswick for decades, but with new projects being proposed and planned across Canada, and tech companies funding a surge of new nuclear projects around the world, we may be entering a new era of nuclear growth. But nuclear power comes with serious baggage, ranging from waste, costs, safety concerns and fears of nuclear proliferation. Researchers working on advancing nuclear technology have been taking lessons from the past to develop safer and more effective nuclear technology for the future.Â
