One of the best things about being a Canadian is the joy of spring. The warm sun, the longer days and the return of songbirds lift our collective spirits. Today in The Conversation Canada, Samantha Knight and Ryan Norris of the University of Guelph write how they have been tracking migratory birds to learn more about the impact of climate change. How do they track them? Tiny little bird backpacks. Don’t believe me? Check out the photo in the article!
In the past few weeks, police in Toronto and California have announced arrests in some particularly gruesome serial killer cases. Criminologist Michael Arntfield of Western University looks at the research into the professions of serial killers – and the results might surprise you. (He also lists the occupations that are over-represented by psychopaths. Check out No. 1 on the list and see if you have the nerve to share the article with your boss.)
NORAD turns 60 this month. Andrea Charron of the University of Manitoba looks at the North American Aerospace Defense Command as it approaches the anniversary and how many are questioning the relevancy of a defence organization that focuses on traditional warfare when most of the threats against North America come from terrorism.
If you want to leave a comment on the article by Maite Taboada of Simon Fraser University, will you be naughty or nice? Prof. Taboada researches how people behave when they comment on news articles and contrary to popular opinion, the “trolls” don’t dominate the comment sections.
