Yet this industrial chemical of great importance has a fascinating history. So important that in 1775 the French Academy of Sciences offered a prize to anyone who could develop an efficient process for producing this substance, commonly known as “soda.” </p> Wed, 11 Dec 2024 22:11:46 +0000 Joe Schwarcz PhD 10195 at /oss /oss/article/medical-history-did-you-know/murder-most-foul <p>One of my favorite detective stories is Agatha Christie's "The Crooked House." The plot revolves around an elderly tycoon who requires daily insulin shots. He also suffers from glaucoma for which he has been prescribed eyedrops. Everything is fine until someone in the "Crooked House" switches the eyedrops with the insulin. Murder most foul!</p> Thu, 05 Dec 2024 18:25:23 +0000 Joe Schwarcz PhD 10189 at /oss /oss/article/medical-critical-thinking-history/fluoride-controversy <p>The nomination of Robert Kennedy Jr. as Secretary of Health and Human Services is a travesty. His ideas about vaccination, raw milk, hyperbaric oxygen, HIV, Wi-Fi and COVID fly in the face of evidence-based science. But once in a while, even a blind squirrel finds an acorn, so not all of Kennedy’s ideas are outrageous. The American diet with its plethora of highly processed foods needs change, the pricing of drugs and some of the advertising antics of pharmaceutical companies need to be addressed.</p> Wed, 27 Nov 2024 19:31:34 +0000 Joe Schwarcz PhD 10180 at /oss /oss/article/medical-history/wolfsbane-has-long-dark-history <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/the-right-chemistry-wolfsbane-has-a-long-dark-history">The Montreal Gazette.</a></em></p> <hr /> <p>“When a doctor does go wrong, he is the first of criminals.

Indeed, more than a hundred-twenty, or over one-quarter of all drugs that currently exist, are derived from plants, although many of these have been chemically modified from their original form so as to improve potency and/or reduce unwanted side effects.</p> Fri, 22 Nov 2024 16:02:03 +0000 Patricia Brubaker, Ph.D., F.R.S.C. 10173 at /oss /oss/article/medical-history-did-you-know/sometimes-luck-serves-springboard-science-0 <hr /> <p><em>This article was first published in <a href="https://montrealgazette.com/opinion/columnists/the-right-chemistry-sometimes-luck-serves-as-a-springboard-for-science">The Montreal Gazette.</a></em></p> <hr /> <p>It is a lifesaver, stocked in every emergency room!

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/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.

Chemists either try to identify existing substances or make new ones. By the early 19th century, a number of substances had been isolated from plants, with morphine from the poppy, quinine from cinchona bark, and coumarin from tonka beans being examples. However, given that these substances were derived from living species, they were believed to be endowed with a “life force” that could not be duplicated in the lab, and that such “organic” substances could not be synthesized.</p> Tue, 22 Oct 2024 16:52:42 +0000 Joe Schwarcz PhD 10124 at /oss /oss/article/history-did-you-know/having-trouble-faces-theres-name <p>If you drive to pick up your child after school and notice that sometimes they go and greet <i>another parent </i>instead who has a car similar to yours, what goes through your head?</p> Thu, 17 Oct 2024 21:57:16 +0000 Jonathan Jarry M.Sc. 10118 at /oss /oss/article/history-did-you-know/we-have-surplus-baby-boys <p>Be honest: have you ever made love to your partner in a specific position because you heard that it would result in a baby boy?</p> Fri, 04 Oct 2024 02:18:15 +0000 Jonathan Jarry M.Sc. 10100 at /oss /oss/article/medical-history-did-you-know/john-daltons-eyeball <p>In 1995, researchers from Cambridge University asked the Manchester Literary and Philosophical Society for a sample of an eyeball that had been sitting in a jar on a shelf since 1844. That eye had made some of the most important scientific observations in history. It—and another just like it—belonged to John Dalton, the English schoolteacher who in the late years of the eighteenth century formulated the atomic theory. </p> Wed, 02 Oct 2024 17:31:08 +0000 Joe Schwarcz PhD 10099 at /oss
