Donald Trump’s renewed tenancy in the White House, with anti-vaxxer-in-chief Robert F. Kennedy Jr whispering in his ear, promises more than just sneezes. It heralds the return of vaccine-preventable illnesses, which do not stop at the border.</p> Fri, 15 Nov 2024 06:40:39 +0000 Jonathan Jarry M.Sc. 10162 at /oss /oss/article/critical-thinking/ballistic-bomb-fizzes-out <p>The advertising is pretty bold. “Feel Good in the Southern Hemisphere! Try a Ballistic Bomb.” They’re not talking about hitching a ride aboard a missile to Australia. They’re talking about the Southern Hemisphere of the body. The part that is immersed in the water in a bath. The Ballistic Bomb is a hardened cake of chemicals that is designed to be dropped into the bath water. It produces vigorous fizzing, supposedly the cause of pleasure in the “Southern Hemisphere,” while releasing a plethora of scents which claim to relax the bather and put a smile on his or her face. </p> Wed, 13 Nov 2024 14:47:11 +0000 Joe Schwarcz PhD 10160 at /oss /oss/article/medical-history-did-you-know/lorenzos-oil-contributed-treatment-devastating-disease <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/the-right-chemistry-lorenzos-oil-raised-awareness-about-a-devastating-disease">The Montreal Gazette.</a></em></p> <hr /> <p>Given that he had trained and practised as a physician before turning to filmmaking, it is no surprise that George Miller was so captivated by the story of Michaela and Augusto Odone’s struggle to save their son from a deadly disease that he decided to turn it into a movie.</p> Fri, 08 Nov 2024 22:05:23 +0000 Joe Schwarcz PhD 10154 at /oss /oss/article/critical-thinking-health-and-nutrition/linoleic-acid-neither-villain-nor-superhero <p>Are you familiar with linoleic acid?

Hair growth occurs in three stages: the growth phase where the hair grows for around 2-7 years, the transition phase where the follicle starts to shrink and hair growth slows for around 2-3 weeks, and the resting phase where the hair falls out at the end of this phase at around 3- 4 months. The falling out of the hair strand is necessary so that a new strand can take its place, and the cycle can begin again.</p> Fri, 08 Nov 2024 15:56:16 +0000 Daniela Padres 10152 at /oss /oss/article/history-did-you-know/chemistry-lesson-farmer <p>The farmer had purchased some potassium permanganate. Exactly why he needed it isn’t clear but using it as a disinfectant to clean the udders and teats of cows before and after milking is a possibility. The compound can also be used to remove iron and hydrogen sulphide from well water. Potassium permanganate is a purple crystalline material that produces a very pretty purple color when dissolved in water. But when dissolved in some other liquids, the story can be quite different, as our unfortunate farmer discovered.</p> Wed, 06 Nov 2024 18:31:21 +0000 Joe Schwarcz PhD 10145 at /oss /oss/article/student-contributors-did-you-know-general-science/chemistry-spider-webs <p>“The itsy-bitsy spider climbed up the waterspout. Down came the rain and washed the spider out…”. But funnily her web remained unscathed. How?!</p> <p>With Halloween having just passed, we saw spider web decorations completely overtake houses, adorn witch hats and even candy wrappers. Despite my fear of spiders, I have an immense amount of respect for them and not for their contributions to our environment. I admire them because spiders are quite the biochemists, and their webs are a product of a biochemical reaction that we can only attempt to reproduce in the lab.</p> Wed, 30 Oct 2024 15:22:54 +0000 Angelina Lapalme 10130 at /oss /oss/article/critical-thinking-history/what-if-dr-kellogg-had-watched-seinfeld <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/the-right-chemistry-what-if-dr-kellogg-had-watched-seinfeld">The Montreal Gazette.</a></em></p> <hr /> <p>Dr. John Harvey Kellogg would have enjoyed The Contest and The Abstinence, two classic Seinfeld episodes.</p> <p>In The Contest, Jerry, George, Kramer and Elaine wager on who can remain master of their domain for the longest time.
