Trent University specialists study the urban habitat of the Brook trout population in Peterborough
August 14, 2017Brook trout, one of only two indigenous trout species in Canada, prefer to live in cold, fast-running streams. But the exact requirements to support a healthy population in an urban setting are unknown. The study by Trent University in conjunction with the Kawartha Field Naturalists is designed to find out exactly what Brook trout require. The population under study live in Harper Creek, which runs along the south edge of the city of Peterborough. Staff have spent the month of July, studying which parts of the creek the trout gather in and will revisit the areas to note any changes. Read the full article here.
The Conversation: How to kill fruit flies, according to a scientist
August 10, 2017As a researcher who works on fruit flies, I often get asked how to get them out of someone’s kitchen. This happens to fly researchers often enough that we sit around fly conferences (these actually exist) and complain about getting asked this question. Meanwhile, we watch the same fruit flies buzz around our beers instead of discussing pithy and insightful questions about the research that we’re pursuing. But I get it: Fruit flies are annoying. So, fine, here’s how we get rid of them in my lab: We build a trap. It’s not perfect, but it’s OK. Read the full article here.
YFile: York U study finds benefits for parents who participate in therapy with autistic children
August 4, 2017Parents of children with autism experience a greater impact from their child’s therapy than once thought, according to new research out of York University’s Faculty of Health. Jonathan Weiss, associate professor in the Department of Psychology, Faculty of Health, and Canadian Institute for Health Research (CIHR) Chair in Autism Spectrum Disorders (ASD) Treatment and Care Research, discovered that parents who participate in cognitive therapy with their children with autism also experience a real benefit that improves the family experience. Approximately 70 per cent of children with autism struggle with emotional or behavioural problems, and may benefit from cognitive behaviour therapy to improve their ability to manage their emotions. “Most of the time when parents bring in their kids for cognitive behaviour therapy, they are in a separate room learning what their children are doing, and are not being co-therapists,” said Weiss. “What’s unique about what we studied is what happens when parents are partners in the process from start to finish. Increasingly, we know that it’s helpful for kids with autism, specifically, and now we have proven that it’s helpful for their parents too.” Read the full article here.
TVO, Opinion: Local news is disappearing in Ontario
August 1, 2017Postmedia owns nearly half of the daily newspapers in Canada, including the major papers in Ottawa and three provincial capitals (Edmonton, Regina, and Winnipeg). It owns all the daily newspapers in several large cities including Calgary and Vancouver. And Postmedia’s dwindling finances mean that it could have to shutter completely or sell off assets in the near future. But more worrying than the fate of those major papers is the future for local news if Postmedia fails. The company owns most of the small dailies published in Ontario – 27, to be exact, in places like Chatham, Cornwall, and North Bay. In some of these communities, there is no other source of news, so Postmedia’s potential demise will affect those communities even more. Northumberland Today is published weekdays in Cobourg and Port Hope, and since Postmedia took it over in 2014, the amount of local news coverage has dropped at an alarming rate. In 2008, 89 per cent of all its content – counting news, photographs and commentary – was local. Today, more than three-quarters of content is syndicated from wire news services like the Associated Press and The Canadian Press, and distributed to all Postmedia papers. Read the full article here.
Toronto Star: Breakthrough discovery helps detect contaminants in supplements using DNA probe
August 1, 2017Researchers at the University of Guelph have developed a new DNA technique to identify if contaminants are present in natural health products with more than one ingredient, like natural medicines, and can even be used to test food quality. The technique was first tested in a recent study on Chinese Patent Medicine, or Chinese medicine that comes in pill, tablet, and capsule forms, 80 per cent of which was found to contain ingredients that were not on the label. “This is quite a breakthrough for industry,” said Steven Newmaster, a professor at Guelph’s integrative biology department and co-author of the study, which was published in Nature, a top-tier scientific journal. “Before the study you wouldn’t be able to take the mixture and disentangle all the species and say they’re there for quality testing. Now you can,” he said. Read the full article here.
CBC: Reducing salmonella risk from contaminated produce studied at Wilfrid Laurier
August 1, 2017Wilfrid Laurier University in Waterloo, Ont. is looking into ways of controlling the presence of the food-poisoning bacteria salmonella on fresh produce as part of a larger project that involves several universities in North America, called Salmonella Syst-OMIC. Salmonella is usually associated with under-cooked or uncooked chicken, but people can also get sick from fruits and vegetables that have been contaminated with the bacteria. Overall, the project looks to improve methods of testing and controlling salmonella in produce, and develop tools for public health departments to determine the source of salmonella bacteria early on when an outbreak happens so that food is removed from grocery stores before someone buys it. Laurier's role in the project focuses on trying to understand salmonella and all 2,500 variations of the bacterium, while researching its ability to produce. Read the full article here.
