Your Poop Is Not Reliable, At Least for Now Let’s say you mail your poop to two different companies—not an illegal act, by the way, provided it doesn’t smell or soil anything, and that it’s packaged and labelled appropriately. It also helps if ...

I will be on CTV Montreal News around 6:20PM ET (in 30 minutes or so) to talk about this new study by NIST about gut microbiome kits.

So much money... all going down the toilet.

The podcasting-to-government-regulation-to-podcasting revolving door is something more people should criticize, I think.

But these microbiome kits are just one more example of scienceploitation (h/t @caulfieldtim.bsky.social). People hear that research is being done, so they expect products, and companies are all too happy to sell them... even if the results are a crap shoot.

But perhaps the most fascinating part of the study is how the national measurement institute of the United States, NIST, spent *years* working on a "human fecal standard," one poop sample to rule them all and in the darkness... well....

Guys, there were "pilot" versions!

Those gut microbiome kits you pay good money for may as well be a ticket to see your local fortune teller.

Seven different companies; a standardized poop sample; and results that are all over the place.

My latest for @mcgilloss.bsky.social.

Is Ozempic maker Novo Nordisk trolling teleheath company Hims & Hers with a new video? A spokesperson from the company told me there was "no connection." Here's a clip from my new @statnews.com video

Last Call for Mass Market Paperbacks After years of steady sales declines, the format will largely disappear next year.

Not quite dead, and of course huge used market, but they are going extinct.

Deceitful AI Videos Mislead Seniors on Important Health Issues I had never received an email in Vietnamese before. My request for an interview had been written in English, and the channel I had reached out to made English-language videos, but the reply I received...

I see more media outlets covering this. I'm about to be interviewed for TVO about it.

I wrote this in early December and it's still fresh.

David Ellison Vows CNN Will Operate Independently as Paramount Buys Warner Bros.: ‘We Want to Be in the Truth Business’ Paramount Skydance's David Ellison maintained that CNN will remain an editorially independent news organization after his company closes its deal for Warner Bros. Discovery.

David Ellison has a beautiful, beautiful bridge to sell you in Brooklyn. Never used, very beautiful.

Some say it's the most bridge that perhaps we've ever seen....

Everyone who tried to draw around me and started drawing LOVED it at the beginning because of their QUICK IMPROVEMENT. Then quit when they hit The Wall™️.

But it's when you hit The Wall™️ that you NEED to push through with practice!! And you gotta do it for yourself, because it's ALWAYS worth it! 😤

You are being misled about renewable energy technology.

WOW. This is a masterclass in beginning with neutral, hand-holding education about renewable energy...

... and then unleashing a hurricane of righteousness.

WOW. Stay until the end. It's well worth the 90 minutes.

Sure. That's one example. But people seem to think that just because something is a peptide, that it'll work just as well as Ozempic.

Peptides are just a class of molecule. There's nothing magical about them.

If you’re wondering why “peptides yes but vaccines no,” it’s partly because a hallmark of conspiracy ideation is rejecting the mainstream and embracing whatever the alternative is.

Vaxx = mainstream = corrupt & bad
Peptides = fringe = secret & good.

If you look at the list of peptides, one of the peptides on that list (Melanotan II) is one where my husband treated someone in the ER who lost the ability to speak in words for half a day after injecting it.

They are "endocrinolologists," which you can become by paying US$ 2,000 to a mail-in university.

Those extra two letters make it so much easier.

Industrial sludge. It's all the rage in the future. Makes you see things.

You have to inject it straight into the heart, though.

Headline from someone's Substack from the year 2100 (because all newspapers are dead):

"Cornelius Ford at the heart of new mayoral scandal."

Because "Cornelius" makes a big comeback in a few decades.

Excerpt from the UATX newsletter. Photo of an anvil with sparks flying around it. "How to Think Like a Founder." UATX x Palantir. April 25, Austin, TX.

Text reads: Palantir built the software the intelligence community used to hunt terrorists. Today they’re one of the most important defense and AI companies on the planet. On April 25, they’re on UATX’s campus for a day — and you get to work with them.

The lineup: First, a UATX seminar on how the American Founders thought about ambition. A real debate on whether AI should make us optimistic or terrified. Then, a hands-on Palantir session on “The Art of Decomposition” — how their teams break impossible problems into solvable ones. A closing reception will be open to families.

Panopticon-deploying evil corporation comes to fake university campus to recruit doe-eyed students who think this is all about free speech.

It’s like when someone from McKinsey came to my campus, but way worse.

This is exactly the sort of photo that, if it hadn't been posted by WaPo, I would think,

"AI."

It's incredible how a quirk is now something you have to monetize, coach people about, turn into your own personal brand.

Guys and gals! I figured out why the year is off to such a terrible start.

Two Friday the 13ths in a row! We had one in February and we have one next week as well. It's some sort of bad-luck nexus.
