May not kill, but have heavy effect on mammals overall health
A new study looking at research on parasitic worms suggests the pesky, but pervasive creatures have a far greater impact on the health of mammal populations than previously known. “Parasites don't have to kill the animal to control a population,” says Kyle Shanebeck, a PhD student in the Faculty of Science’s Department of Biological Sciences…
Studying living habitats that attract and retain different organisms is crucial in restoration planning
Researchers have devised a new method of making lifelike aquatic artificial habitats that could help scientists better understand and restore real-world environments. Aneri Garg, who completed the research as part of her master’s studies under the supervision of Stephanie Green, first developed the 3D scanning, printing, moulding and casting (3D-SPMC) method on a project involving coral reefs. As…
Banning junk food advertising may have little effect on reducing obesity
A new study from the University of Alberta challenges the notion that advertising junk food is at the root of the obesity epidemic. Growing up in a low social-economic environment is more of a precursor to obesity later in life than junk food advertising, according to the report, with adults who grew up in a…
New research suggests beavers may be susceptible to the fatal illness – increasing spread between species
Chronic wasting disease (CWD) is an infectious disease that affects the central nervous systems of animals, typically affecting cervids such as deer, elk and moose. “CWD is always fatal. There’s no cure; there are no treatments,” says Debbie McKenzie, a professor in the Department of Biological Sciences. CWD is increasing its geographic range as well…
Findings show promise for new anti-inflammatory drugs and treatments for autoimmune diseases
New research shows a group of enzymes may have a critical role in how immune cells are activated and then migrate to certain sites in the body – findings that could improve our understanding of inflammation and potentially lead to new treatments. In a recent study, researchers explored a particular family of enzymes called neuraminidases. "We…
These magnificent birds often nest in odd places, such as the light standards and hydroelectric towers
The waterfront of Port Perry, Ont., is hosting new neighbours. Two osprey have taken up residence right in the middle of town on the waterfront. These magnificent birds inspire awe but often nest in odd places, such as the light standards and hydroelectric towers. A pair has nested for years at the ball fields at…
Fergus McSween is applying his new knowledge of forests, plants and animals to help protect them
Fergus McSween loves the outdoors. Growing up in Calgary, he spent much of his youth outside the city, roaming Alberta’s forests as a Scout, on school outdoor education trips, or camping with friends and family. “Nature is so peaceful and tranquil. It’s a place where I can be myself, turn my brain off and just…
The large-scale study adds to the understanding of how different grazing practices affect the land
The way ranchers graze their cattle doesn’t make much difference in plant diversity on the land, according to a U of A study. That’s important because plant diversity is a useful metric to gauge the resilience of a landscape, including rangeland used by cattle producers, says Jessica Grenke, first author of the study. Researchers compared adaptive…
Edmonton Protocol team reports treatment is safe and reliable for people with hard-to-control diabetes
After 20 years of perfecting their technique, the team behind the largest islet transplant program in the world reports the procedure is a safe, reliable and life-changing treatment for people with hard-to-control diabetes. In results published recently in The Lancet Diabetes & Endocrinology, the researchers report on patient survival, graft survival, insulin independence and protection from life-threatening low…
Maricor Arlos grew up around water, but when she came to Canada she found purpose in sustaining it
Growing up in the Philippines, a country in the western Pacific Ocean made up of 7,107 islands, Maricor Arlos didn’t think much about the water that surrounded her. With no central sewage system, many households in the Philippines have septic tanks or other forms of decentralized waste collection that would be cleared out periodically without…
