How changing boreal forests could affect caribou

Researchers examine what logging, climate change and other factors mean for caribou populations

How changing boreal forests could affect caribouNew research by University of Alberta biologists paints a clearer picture of how food webs are shifting in response to changing habitats in Canada’s boreal forests, and what it means for dwindling caribou populations. “We know that habitat, prey and predators such as wolves are all pieces of the caribou conservation puzzle, and here we…

How do we fairly welcome trans athletes to playing fields?

The general approach should be to have experts in each sport come together and decide on the specific rules for allowing fair competition

How do we fairly welcome trans athletes to playing fields?Most of the sports issues I write about are pretty straightforward – at least in my mind. The solutions seem pretty clear. Do big-time college athletes deserve a bigger slice of the billions being made from their efforts? Undoubtedly. In an era in which childhood obesity is at epidemic levels, and teenage anxiety, depression and…

Any memory boost from morning exercise is short-lived

U of A undergrad researcher finds surprising effect on memory eight hours after physical activity

Any memory boost from morning exercise is short-livedExercising first thing in the morning makes long-term memory recall increasingly hard as the day continues, according to surprising results from an undergraduate student-led study that challenges conventional wisdom about the positive role physical activity plays in making new memories. “If you’re going to exercise in the morning, you might have a little trouble remembering…

Bridge to Life commits US$10 million to clinical trial and commercial development of Tevosol Ex-Vivo Organ Support System

U of A spinoff, U.S. firm merge to commercialize transplant technologyUniversity of Alberta spinoff company Tevosol has merged with the U.S.-based medical technology company Bridge to Life, bringing its game-changing organ transplant devices a step closer to approval, manufacture and global distribution. While Tevosol will remain based in Edmonton, Bridge to Life has committed US$10 million to a multi-centre clinical trial and commercial development of Tevosol’s Ex-Vivo Organ Support…

Fat cells may influence how the body reacts to heart failure

Promising results in mice open door to new areas of research in treating patients

Fat cells may influence how the body reacts to heart failureResearchers have found that limiting the amount of fat the body releases into the bloodstream from fat cells during heart failure could help improve outcomes for patients. In a recent study published in the American Journal of Physiology, Jason Dyck, professor of pediatrics in the Faculty of Medicine & Dentistry and director of the University of Alberta’s Cardiovascular Research Centre, found…

Potential new treatments for cardiovascular disease

Researchers have identified a new mechanism responsible for the buildup of plaque on artery walls

Potential new treatments for cardiovascular diseaseGlycomics researchers at the University of Alberta and CHU Sainte-Justine have reported a discovery that could lead to new treatments for cardiovascular disease. The researchers identified a new mechanism responsible for the buildup of plaque on artery walls, a process known as atherosclerosis. This plaque, made up of fats, cholesterol and other substances, can restrict…

Tracking common nighthawks to shed light on declining populations

U of A biologists track the migratory birds over 10,000 km with GPS to study their route – and the cause behind their declining numbers

Tracking common nighthawks to shed light on declining populationsA new study by University of Alberta biologists has created a comprehensive picture of the 10,000-km migratory route of common nighthawks using GPS data. The study is the first step in analyzing where and why the birds’ population numbers are declining. “Like many migratory bird species, common nighthawks are declining, but the rate of those…

New way identified to track severity and progression of ALS

Researchers hope to move toward earlier diagnosis and effective treatments

New way identified to track severity and progression of ALSUniversity of Alberta researchers have discovered a new method to identify the severity of Lou Gehrig’s disease in patients and track its progression. The U of A team, led by Sanjay Kalra, a professor in the Division of Neurology, has made progress toward an imaging biomarker for white-matter degeneration in the brains of ALS patients. They hope…

New research provides insight into evolutionary origin of the eye

Hagfish eyes uncover unexpected similarities to those of other vertebrates, including humans

New research provides insight into evolutionary origin of the eyeThe answer to the age-old mystery of the evolutionary origins of vertebrate eyes may lie in hagfish, according to a new study by biologists at the University of Alberta. “Hagfish eyes can help us understand the origins of human vision by expanding our understanding of the early steps in vertebrate eye evolution,” explained lead author…
