The elegant and essential cones of coniferous trees

Many birds explore the nooks and crannies of these seed-bearing pods as they try to pry the seeds loose or find minute insects

The elegant and essential cones of coniferous treesAs we welcome spring, we see the remnants of pine and spruce cones previously covered by snow. Few of us think about how important these cones are to the floral and faunal communities – as food and to ensure the next generation of trees is born. Many species of coniferous trees produce cones – pines,…

Study sheds new light on how huge carnivorous dinosaurs moved

International study sheds new light on how the huge carnivorous dinosaurs moved, based on fossil evidence of their footprints

Study sheds new light on how huge carnivorous dinosaurs movedNew research by an international team including paleontologists at the University of Alberta and the Philip J. Currie Dinosaur Museum has revealed evidence that juvenile tyrannosaurs were more trim and slender-bodied than their multi-tonne elders, a difference that may have helped them pursue fast-moving prey. “The results suggest that as some tyrannosaurs grew older and…

Snake jaw structure yields new understanding of evolutionary origins

Study re-examining what early snakes might have looked like

Snake jaw structure yields new understanding of evolutionary originsNew research led by a University of Alberta graduate student could lead to reimagining what early snakes might have looked like, suggesting that some of the world’s supposedly simplest snakes have a more complex evolutionary history than traditionally thought. Snakes are broadly divided into two groups based on their feeding mechanisms: macrostomatan snakes, able to…

Safer source of islet cells targeted for people with Type 1 diabetes

U of A researchers are harnessing AI to analyze patients’ own cells to create islet cells for transplant

Safer source of islet cells targeted for people with Type 1 diabetesUniversity of Alberta researchers are harnessing the power of artificial intelligence to find a safer, more personalized source of islet cells to treat Type 1 diabetes. The research project, a collaboration between the departments of surgery and computing science, aims to use AI to analyze images to speed up the process and reduce the need for human decision-making…

Tackling heart disease in people with Type 2 diabetes

U of A pharmacy researcher looks for ways to correct a common but often hidden type of diabetes-related heart failure

Tackling heart disease in people with Type 2 diabetesA University of Alberta laboratory has uncovered a new approach to preventing heart failure in people with Type 2 diabetes, according to research findings published recently in the journal Cell Reports. “We know people with diabetes take drugs for years to control their blood sugars, but the drugs don’t cure their diabetes,” said lead author John Ussher, associate…

Protein that blocks body’s ability to clear bad cholesterol identified

Researchers are now looking to develop a drug that will boost existing statin drugs to prevent heart disease

Protein that blocks body’s ability to clear bad cholesterol identifiedA team of researchers at the University of Alberta has uncovered a long-sought link in the battle to control cholesterol and heart disease. The protein that interferes with low-density lipoprotein (LDL) receptors that clear ‘bad’ cholesterol from the blood was identified in findings recently published in Nature Communications by Dawei Zhang, associate professor of pediatrics in the Faculty…

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…

U of A spinoff, U.S. firm merge to commercialize transplant technology

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…
