HIV/AIDS Denialism Is Back, Courtesy of Joe Rogan

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.

When Your Phone Makes Time Disappear

Lia Erisson — Fri, 13 Mar 2026 18:41:46 +0000

When I think about the first few hours of my day, I picture myself getting up, making breakfast, picking out my outfit, and tidying my apartment. What I don’t often recall are the 30 or so minutes I spend doomscrolling on Instagram or playing video games as soon as I wake up. To be honest, that time barely registers as having existed at all.

In all likelihood, you have similar experiences in your day-to-day life.

BPC-157 – No Proof Required!

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.

White Noise May Worsen Sleep

Getting a good night’s sleep is paramount to health; and yet, whenever we reach for a sleep aid, we are told there are risks involved.

COP30: Reclaiming the Truth

Eva Kellner B.A.Sc. — Fri, 06 Mar 2026 11:00:00 +0000

On January 7th, 2026, Donald Trump explicitly withdrew the United States from the Intergovernmental Panel on Climate Change (IPCC), along with 65 other organizations. His reasoning was that these organizations and treaties “no longer serve American interests.” This action is one of Trump’s many attacks on the integrity of climate change.

Interesting Chemistry Hides in Cookware

Joe Schwarcz PhD — Thu, 19 Feb 2026 13:57:51 +0000

Like most chemists, I like to cook. After all, what is cooking but the appropriate mixing of chemicals? In the lab we use flasks and beakers, but how do we equip our kitchen? Tiffany's in New York offers a silver frying pan for thousands of dollars, specialty stores sell gleaming copper pots for a couple of hundred, while a thin aluminum pot can be had most anywhere for a few dollars. What's the difference?

Degree ABCs

Five minutes on health TikTok is all it takes. A pair of scrubs. “Dr.” in the bio. And a confident voice assuring you they can detox your liver, balance your hormones, or fix your chronic illness, with a supplement conveniently available through the link in their profile.

Credentials are flashed like VIP wristbands on social media, but what do they actually mean?

The Gold Rush of Testosterone Replacement Therapy

If you’ve never injected yourself with dog semen, don’t worry: someone has done it for you.

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.

The Frivolous Costco Chicken Lawsuit

Joe Schwarcz PhD — Wed, 04 Feb 2026 21:21:30 +0000

Talk about a frivolous lawsuit! These two ladies claim that they have been misled by the information on the label of Costco’s famous rotisserie chicken that states “no preservatives.” Why? Because the listed additives include sodium phosphate and carrageenan. That, they say, merited a lawsuit! They go on to say that Costco "has systematically cheated customers out of tens, if not hundreds of millions of dollars by falsely advertising its Kirkland Signature Seasoned Rotisserie chicken as containing no preservatives.” Really? Who exactly is doing the cheating here?

Dr. Michael Greger’s Bias Is Food for Thought

Jonathan Jarry M.Sc. — Fri, 30 Jan 2026 11:00:00 +0000

How can we distinguish between a sufficiently objective science communicator and an advocate? Communicating science to the public means choosing scientific papers, reading them, and appraising their worth before synthesizing all of this knowledge. We try to do it as impartially as we can… but what if we are ideologically biased?

“Food Preservative Linked to Cancer,” Shrieked Many a Headline

Joe Schwarcz PhD — Thu, 22 Jan 2026 23:23:20 +0000

It isn’t surprising that a paper published in the prestigious British Medical Journal linking food preservatives to cancer roused much media attention. After all, preservatives in food are not rare and cancer is frightening. But just how much should our eyebrows furrow? That depends on whether you look at the headlines that scream about preservatives increasing cancer rates by 16% or you delve deeply into the data that gave rise to these numbers. Let’s delve!

A Case Study in Magical Thinking: Scentbird’s CEO

Jonathan Jarry M.Sc. — Fri, 23 Jan 2026 11:00:00 +0000

We often turn to successful people for advice. Bookstore shelves are heavy with tomes adorned with photos of rich luminaries resting their head on their fist, and podcasts can’t get enough of famous stars explaining how they got to where they are.

By following their breadcrumbs, we hope for similar outcomes, but the thing is, chance plays an outsized role in success. Those who ascend to the top may not be smarter or more rational than us, just luckier.

A Beginners Guide to Time Travel: Explaining the Time Zones

Eva Kellner B.A.Sc. — Fri, 16 Jan 2026 11:00:00 +0000

In a way, time travel does exist. Just hop on a plane from Montreal to Vancouver, and you jump back three hours. Or better yet, fly in the other direction to Auckland, and find yourself 18 hours in the future. Of course, we owe these time differences to the Earth’s rotation, but also to the human-decided lines that identify various time zones. (This subject is, in fact, very personal to me because I am currently writing this at 5:30 in the morning due to the infamous jetlag most of us have experienced at some time.)
