U of G researchers work to improve cancer treatments

cancer treatment

Cancer treatment may become more effective thanks to University of Guelph physicists who have developed an innovative way to accurately target radiation therapy. Radiation therapy aims beams of intense energy at a tumour to kill cancer cells. But if the ultranarrow beam is aimed inaccurately, it can hit healthy cells and “underdose” the target tumour. Led

Using cannabis when you’re young may increase your risk of developing heart disease later, according to a University of Guelph study. In the first study to look at specific risk indicators for cardiovascular disease (CVD) in young, healthy cannabis users, researchers found increased arterial stiffness and lower cardiac function than in non-users. “Cannabis is really

Bee spotted in Canada points to climate change impacts

A bee species recorded for the first time in Canada by University of Guelph researchers may provide further evidence that critical pollinators and other creatures are widening their natural ranges under climate change. The team members also say this first-ever Canadian sighting of the American migrant underlines the importance of maintaining a unique habitat in

Neonic-treated milkweed an ‘ecological trap’ for monarchs

A commonly used neonicotinoid pesticide may harm monarch butterflies, University of Guelph research has revealed. The findings could help explain the recent massive decline in the North American monarch population. Led by U of G integrative biologist Dr. Ryan Norris, two studies examined effects on monarch caterpillars raised on milkweed treated with the insecticide clothianidin,

Palm oil alternative good for human, environmental health

A discovery by University of Guelph food scientists could lead to a healthier, more affordable and more sustainable substitute for palm oil, which poses health and environmental problems. Palm oil is high in saturated fats, which increase the risk of coronary heart disease. Felling tropical forests for large-scale palm oil plantations, especially in Southeast Asia, destroys habitat
