Research is the engine of science. But that engine should not be idling, it should be steadily propelling science forward. The extent of that forward motion is to be found in the estimated 10,000 papers spewed out every day by the world’s 45,000 or so peer-reviewed scientific journals.

Why do we Crave Junk Food During Stress?

Have you ever noticed that during exams, deadlines, or stressful life events, a salad suddenly sounds much less appealing than a bag of chips or a chocolate bar? You're not imagining it. Chronic stress can change the way our brain and body respond to food, increasing cravings for sugary and fatty "comfort foods.

Creatine a Supplement With a Rare Commodity: Evidence

I have always been a fan of the Olympics, particularly the 100-metre sprint to decide “the world’s fastest human.” Like all Canadians, I was elated when Ben Johnson won the event at the 1988 Seoul Olympics, then devastated when we learned that he had cheated by doping with stanozolol, a muscle-building synthetic steroid.

Should We Be Reaching for that Greek Cup of Coffee?

According to Greek mythology, Icarus tried to soar like a bird with wings he had fabricated out of feathers. Unfortunately, he plunged into the sea after the wax with which he had attached the wings melted when he flew too close to the sun. The Greek Island of Ikaria was named after Icarus and has become a focus for longevity researchers because along with Okinawa in Japan, Sardinia in Italy, the Nicoya peninsula in Costa Rica and Loma Linda in California it boasts unusually high rates of longevity.

Forget the Supplements and Bring On the Berries

Resveratrol Supplements. Trifling Facts. Lots of Conjecture.

Joe Schwarcz PhD — Thu, 02 Jul 2026 13:32:12 +0000

A quick online search for “resveratrol supplements” finds dozens produced by various companies. They contain anywhere from 50 to 500 mg resveratrol per capsule and sport labels that scream “source of antioxidants.” But there is no mention of any condition that resveratrol is expected to treat or prevent. For good reason! While there is plenty of speculation about what this compound can do based on laboratory experiments that use cell cultures, yeasts, worms, flies or rodents, it is best to remember that humans are not giant test tubes or colossal rodents.

Quackery in Quebec: The Trojan Horse Bill I Worry About

Jonathan Jarry M.Sc. — Fri, 26 Jun 2026 13:13:56 +0000

A new bill has been proposed at the National Assembly of Quebec, and while it may look like it will benefit our health, there is a lot going on under the surface. It is an excellent example of how the rebranding of pseudoscience gives it legitimacy, and this Trojan horse is now knocking on our legislative door.

Handling Receipts at the Supermarket

Joe Schwarcz PhD — Thu, 18 Jun 2026 18:18:08 +0000

I was startled by the comment from the shopper just behind me at the checkout counter in the supermarket. “You really shouldn’t be doing that!” Noting the quizzical look on my face, a further clarification was obviously needed. “I mean you shouldn’t be handling the receipt,” she went on. Indeed, I had taken the thermal paper receipt from the cashier and without looking at it tossed it in with the groceries. I now understood my fellow shopper’s concern.

Blue Light Vs. Red Light

There is an epic fight unfolding between the light side and the dark side of, no, not the Force, but the light spectrum itself. You will have seen the countless gadgets claiming to heal you with red light—the creepy masks full of LEDs, the therapeutic light boxes, even the full-body infrared saunas. Red light, we are told, has health benefits.

Let’s Rap About Rapamycin

Easter Island in the Pacific off the coast of Chile is famous for the giant stone statues that were erected by natives some 500-700 years ago. The thinking is that the statues were designed to honour eminent ancestors by providing a home for their spirits to inhabit. In the 1960s, Easter Island made it into headlines for a totally different reason. Soil samples were found to contain Streptomyces hygroscopicus, a bacterium that produces a chemical with antifungal activity.

Aspartame: Not the Devil Incarnate but Not A Godsend Either

Joe Schwarcz PhD — Thu, 28 May 2026 23:43:46 +0000

Long before “wellness influencers” honed the art of spreading misinformation on the internet, the public was at the mercy of being befuddled by hoaxes through chain emails. Way back in the 1990s, I was the recipient of one of these from “Dr.” Betty Martini in which she described a speech given by one Nancy Markle at the “World Environmental Conference” in which she claimed that the artificial sweetener aspartame was the cause of multiple sclerosis, chronic fatigue syndrome, seizures, brain tumours, lupus and Alzheimer’s disease.

Exaggerated Fears Over Cancer Biopsies Can Worsen Cancer

Jonathan Jarry M.Sc. — Thu, 28 May 2026 22:54:23 +0000

Fear of the needle is not reserved to the vaccine hesitant; it extends to biopsies as well. In corners of social media where misinformation accumulates, influencers with an axe to grind against doctors are warning people to stay away from biopsies that help diagnose a cancer. “NEVER do a prostate biopsy, NEVER do a breast biopsy,” you will read, as the biopsy is said to spread the very cancer it is sampling.
