On the side are some salmon rice balls. Noting I missed some greenery, I grab some grass and sprinkle it onto my rice balls.</p> Fri, 20 Jun 2025 10:00:00 +0000 Shona Hanaishi 11237 at /oss Disrupting Science with Crypto /oss/article/critical-thinking-technology/disrupting-science-crypto <p>Let’s say I am afflicted by a common but non-life-threatening condition. I shall refer to this fictional misfortune as “chin gribbles.” I have chin gribbles. Many people have chin gribbles. It’s annoying and it affects our quality of life. When we go to the pharmacy or speak to a doctor, we’re told there are very few treatment options for chin gribbles, if any.</p> Fri, 06 Jun 2025 18:04:27 +0000 Jonathan Jarry M.Sc. 11121 at /oss Your Blood Predicts Alzheimer’s Disease /oss/article/medical-technology/your-blood-predicts-alzheimers-disease <p>My first laboratory job was right after earning my Master’s degree, and it was on a research project on Alzheimer’s disease. I had to test DNA samples from participants for a particular form of the gene <i>APOE. </i>We get one copy of the gene from our mother and another from our father, and this gene like all others comes in different flavours. People who had a very specific form of the <i>APOE </i>gene, I learned, were predisposed to Alzheimer’s disease.</p> Fri, 23 May 2025 10:00:00 +0000 Jonathan Jarry M.Sc. 11101 at /oss Confronting Nefarious Nitrosamines /oss/article/health-and-nutrition-technology-general-science/confronting-nefarious-nitrosamines <p>“Boil the nipples!” was the advice given in 1984 by the Food and Drug Administration in the U.S. to parents who were bottle feeding their infants or calming them with pacifiers. The presence of nitrosamines, compounds that had been found to cause cancer in animals, had been recently detected in rubber products and the concern was that they could be transferred to babies.</p> Fri, 09 May 2025 20:44:53 +0000 Joe Schwarcz PhD 11010 at /oss RECCO Reflectors Echo Safety Signals /oss/article/technology-did-you-know-general-science/recco-reflectors-echo-safety-signals <p>A goal of mine in 2025 was to tackle a new outdoor sport: backcountry skiing. With the promise of untracked snow and uncrowded runs, venturing off-piste was enticing. But with that also came the need to ensure safety — I geared up with an avalanche kit, most of which was intuitive: Shovel? Check. GPS? Check. But one thing that kept coming up was the RECCO tag on all sorts of gear.

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 Oh, That Bathtub Ring! /oss/article/technology-general-science/oh-bathtub-ring <p>In 1933 Calgon Incorporated of Pittsburgh introduced its flagship product, appropriately named “Calgon.” The name was derived from the phrase “calcium gone,” which was an accurate description of what the product was designed to do, namely soften water. Hard water has a high content of dissolved minerals, mostly salts of calcium and magnesium. Various problems ensue when the concentration of these is greater than about 120 mg per liter. Unlike the sodium salts of fatty acids that are the basis of soaps, their calcium and magnesium salts are insoluble, resulting in the classic bath tub ring.</p> Wed, 16 Oct 2024 19:49:35 +0000 Joe Schwarcz PhD 10115 at /oss Tiny MicroRNAs Win Big Nobel Prize /oss/article/technology-general-science/tiny-micrornas-win-big-nobel-prize <p>It may surprise you but when microRNAs were discovered, the scientific community shrugged. “So what?” it seemed to say.
