While camping this weekend, I got to mind a very cute 7-month-old baby. She was super social, giggly and sporting a patch that inspired this article. As she laid her head on my shoulder, I noticed a pink patch on the back of her shirt collar. I asked her grammie what it was, and she said that the baby’s mom makes her wear this “mosquito patch” to keep the bugs away. My immediate thought was, does it actually work?

Vladimir Lenin lies in a mausoleum in Red Square in Moscow in a preserved state. 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! The item in question was sent to Oskar Vogt, a well-known German neuroscientist, who spent a couple of years studying it. His conclusion?

It was the 1960’s and cheese producers were cheesed off. People were just not eating enough veal. Slaughterhouses were running short of calf stomachs and the cheese industry was feeling the pinch. There was not enough rennet to meet the demands of turophiles (that's "cheese lovers" from the Greek “turo” for cheese) around the world.

Mention Frankenstein, and what springs to most people's minds is Boris Karloff’s portrayal of the “monster.” That's because they’ve skipped the book and seen the movie, which is a true Hollywood-style horror story. In writing her novel, Mary Shelley did not intend to scare her readers—what she penned was a work of science fiction that explored the consequences of allowing science to go astray.

Joe Schwarcz PhD — Wed, 14 May 2025 13:57:24 +0000

Gutta percha is the hardened latex of the Palaquium gutta tree, originally native to Malaysia. This is a natural “thermoplastic” substance, meaning it can be softened with heat and shaped into a form that is retained on cooling. Gutta percha was introduced to Europe in 1842 by Dr. William Montgomerie, a surgeon serving with the British army in the East Indies who had originally come across the substance in Singapore where it was being used to make handles for machetes. He thought the substance would be useful to produce handles for medical devices as well as splints for fractures.

History

John Napier is credited with discovering/inventing logarithms but nature had already beaten him to it. Our bodies had already figured it out. Our senses—sight, hearing, taste and touch— use a logarithmic transform to cope with the enormous range of the signals our senses need to handle.
