The Curious History of Coca-Cola’s “Fanta” Beverage

Joe Schwarcz PhD — Wed, 08 Apr 2026 18:18:32 +0000

Coca Cola, the beverage that sports the most recognized trademark in the world, has a fascinating and sometimes quirky history. It all started with a battlefield wound suffered in 1865 by Confederate officer John Stith Pemberton during the American Civil War. Pemberton had obtained a medical degree at the age of nineteen and had a special interest in chemistry so when he developed chronic pain due to his injury, he knew what to do. Morphine! It solved the pain problem, but Pemberton became addicted to the drug. That triggered a search for a pain killer that was not addictive.

Earlier this year, the United States dramatically scaled back its universal childhood immunisation schedule recommendations. Under an overhaul spearheaded by US Health Secretary Robert F. Kennedy Jr., the number of diseases for which vaccines are universally recommended dropped from 17 to 11. Vaccines for polio and measles remain on the list, but others—like hepatitis A, hepatitis B, and Covid-19—are now recommended based on risk or “shared clinical decision-making” between doctors and parents.

It doesn’t matter how good a video or an article is if you can’t get people to watch or read it. That’s why a lot of thought goes into coming up with a catchy title that grabs attention. In this case, since I’m talking about the possible health benefits of beets, the root vegetable, a headline just about writes itself. “You can’t beat beets.”

Red hair is the rarest natural hair color, expressed in only 1-2 percent of the world’s population. Of course, that number does not include salon-goers who seek to mask their original hair color.

Is Your Sauna Session Sabotaging Your Swimmers?

Over the past few months, a not insignificant number of my male friends have asked me (unprompted) whether going to the sauna is ruining their sperm. Bold questions. Intimate questions. But fair ones. Sauna culture has exploded in North America, and with it, men now face an understandable worry: is the sauna accidentally slow roasting fertility?

Joe Rogan, the most influential podcaster globally, is an HIV-AIDS denialist. Imagine the backlash if the six o’clock news were espousing this decades-old, harmful pseudoscience front and centre.

The actions of the stomach are an important first step in the digestion of the food that we eat. This occurs in part through mechanical grinding of large ‘clumps’ of food into smaller pieces for passage into the intestines. However, cells that line the stomach also secrete a number of compounds into the gastric cavity. These include hydrochloric acid (HCl), as well as a number of complex proteins and a few much smaller proteins known as peptides.

The banging on the door at 3 in the morning of March 12, 1938, by Gestapo agents was fierce. They were rousing Otto Loewi out of bed to drag him off to jail. His crime? Loewi was Jewish. It didn’t matter that two years earlier he had been awarded the Nobel Prize for a landmark experiment that was destined to change the course of medicine.

Paying Attention to My Own Lectures

“It builds muscle!” That’s the usual answer I get when I ask in class about the importance of protein in the diet. Sort of correct since muscles are indeed composed mostly of protein, but the protein we eat does not directly build muscles. It is broken down during digestion into its constituent amino acids that are then pieced together by enzymes (also proteins) to become the proteins that make up muscle tissue.

The light at the end of the pandemic tunnel was marred by a worrying shadow. As the COVID-19 vaccines were rolled out, headlines fuelled anxiety: some people were developing life-threatening blood clots after receiving either the Johnson & Johnson vaccine (made by one of its subsidiaries, Janssen Vaccines) or the Oxford-AstraZeneca shot.

The Placebo Myth Picked the Wrong War

Jonathan Jarry M.Sc. — Thu, 05 Feb 2026 13:43:10 +0000

There’s a medical myth with which a friend of mine and I have become obsessed: this idea that scientific research into the “placebo effect” began in earnest during World War II. As I’ve written before, the classic story is that Dr. Henry Beecher, a Harvard graduate transported to a military base hospital during the darkest days of the 20th century, ran out of morphine while treating soldiers in pain.
