The worst patients to reset fractures on, she said, were men in their thirties. They scream, beg for anesthetic, and prolong the process as much as humanly possible. The best patients? Women in their sixties, who will sit unflinchingly still and remark in surprise when the process is “over already”.</p> Thu, 26 Feb 2026 23:22:43 +0000 Sophie Tseng Pellar BSc 11914 at /oss Degree ABCs /oss/article/critical-thinking-student-contributors-pseudoscience-did-you-know/degree-abcs <p>Five minutes on health TikTok is all it takes.

His reasoning? Its prophylactic effects against seasonal depression. In his words: “[it is] the most important thing you can do for your mental health.” For many years, I haphazardly followed his advice, both out of the appreciation I had for him to think about my wellbeing in the face of winter’s darkness, but also because I figured, why not? But can regularly taking vitamin D really have such an effect?</p> Fri, 30 Jan 2026 11:00:00 +0000 Eva Kellner B.A.Sc. 11881 at /oss A Beginners Guide to Time Travel: Explaining the Time Zones /oss/article/critical-thinking-student-contributors-history-did-you-know/beginners-guide-time-travel-explaining-time-zones <p>In a way, time travel does exist. Just hop on a plane from Montreal to Vancouver, and you jump back three hours. Or better yet, fly in the other direction to Auckland, and find yourself 18 hours in the future. Of course, we owe these time differences to the Earth’s rotation, but also to the human-decided lines that identify various time zones.

We are talking pizza! Although I’m a fan, and know all about “four-cheese pizza,” I’ve never come across “pizza quattro stagioni,” or “four-seasons pizza,” that is divided into four sections with each section representing one season of the year. Prosciutto and olives represent winter, artichokes spring, basil and tomatoes summer, and mushrooms represent autumn. Of course, there is always a base of tomato sauce and cheese.</p> Fri, 19 Dec 2025 21:02:34 +0000 Joe Schwarcz PhD 11849 at /oss A Bear’s Den and a Spaceship May Have More in Common Than You Think /oss/article/student-contributors-environment-did-you-know-general-science/bears-den-and-spaceship-may-have-more-common-you-think <p>Having recently moved to Prague, I have spent many of my weekends in the Czech countryside.

But he has no brain. That’s because the Soviet government had it removed after he died in 1924. They wanted to have the brain examined scientifically to see how it differed from that of mere mortals. After all, someone who thought up something as clever as communism must have had a very special brain!
