Jay's passion for replication famously only applies to research he doesn't already agree with.

How...concerning. The team in question produced some rather problematic research on COVID-19 vaccines, so this is perhaps unsurprising.

Screw getting to Mars, I want science to figure out a way of getting newborns to sleep through the night from day 1.

Why did the racist head of The Racist Party post a racist meme on his racist website? No one is sure, but here's one white man's opinion.

This is a very cool study and, as far as I can tell from a quick read, robust. Statins probably don't cause most of the side-effects that people think they do. www.thelancet.com/journals/lan...

The term ultra-processed food is ridiculous and the entire idea is a painfully silly extension of the naturalistic fallacy

Vitamin D supplements still probably don't prevent respiratory infections, despite the new ridiculous headlines. Sigh. Honestly, what are we even doing here? gidmk.substack.com/p/vitamin-d-...

During the peak of the Covid-19 pandemic, I taught three, online courses for journalists on basics of epidemiology Course recordings and slides are still available as a free resource on my teaching website www.teachepi.org/courses/epid...

HAHAHAHA John "COVID-19 will only kill 10k people, oh wait 40k people, it's not a problem everything is fine" Ioannidis is criticising science journalists for dipping into advocacy.

I get it—one can “love the art, not the artist,” & there are plenty of musicians who made beautiful music while being problematic (eg, read Ryan Walsh’s book “Astral Weeks”) But when a band played a key role in the deaths of hundreds of thousands of people & NEVER apologized, a threshold is crossed

Maggiore was famously supported by the Foo Fighters who were major HIV/AIDS denialists and have never apologized for their role in 100ks of deaths.

It really is remarkable how little Jay knows about anything COVID-19 related given that it has been his entire platform and area of interest for 6 years.

My new piece for Slate is about whole milk and why RFK Jr.s obsession with it is absurd even according to his own scientific data. slate.com/technology/2...

our health leader seems to be under the mistaken impression that whole milk is more "natural". by @gidmk.bsky.social slate.com/technology/2...

Do common food preservatives give you cancer and diabetes? Despite the scary headlines, probably not. My new piece. gidmk.substack.com/p/preservati...

Great piece by @bethskw.bsky.social on that new study showing that diet soft drinks are possibly healthier than water: au.lifehacker.com/fitness/1173...

Morgan's interview with me was my fave one! She really got the heart of so many of my book's points. If you missed it, check it out....

COVID-19 has never been less of a problem than it is today. A piece inspired by @michaelsfuhrer.bsky.social open.substack.com/pub/gidmk/p/...

We are increasingly exposed to surveillance and algorithmic classification but with little appreciation for the risk false positives and the costs of those errors.

Whichever editor chose the journalist to cover the new Sydney Fish markets is lowkey a genius.

This is, of course, why all good mothers fly their own planes when travelling.

A few updates on the deeply unethical study to probe "non-specific" effects of the birth dose HepB vaccine in Guinea-Bissau by Danish investigators. 1️⃣ The study was canceled as per AfricaCDC - HHS disputes this. 2️⃣ Full protocol was leaked and it's bad. Quick 🧵 www.theguardian.com/us-news/2026...

⚠️ I think there's been far too little attention paid to what RFK Jr's overarching plan is: End science-based, evidence-based approaches to reducing illness, suffering, & death (e.g., vaccination, fluoridation of water) and replace them with bogus, unproven, kooky approaches (beef tallow, chelation)

🧪 The "high-profile study" in question here is one *the Guardian reported on* just under a year ago with a "shocking" headline. That story includes sections of the study copy-pasted and additional quotes from the UK science media centre that lacked their full context about why the study was flawed.

Long and useful thread showing why the people constantly saying that the pandemic never declined based on waste water data are wrong. COVID-19, since it emerged, has never been less of a problem than it is today.

Fascinating piece about how the fear of microplastics is almost certainly overblown. One takeaway for me is that even the scientists behind the microplastics=bad papers are VERY reserved about whether these findings are really problematic. www.theguardian.com/environment/...

My first piece of the year looks at artificial sweeteners and why they may be...healthier than water?? Thanks to @tamarhaspel.bsky.social for the inspiration! gidmk.substack.com/p/diet-coke-...

Nothing like a newborn snuggle in the morning 💖

I'm shocked that Michael Shermer thinks that women should just stay home and keep their mouths shut.

Thoughts about Peppa Pig: 1. Why do they all have human teeth? 2. The zoo in this world is a dystopian nightmare. 3. George is nowhere near meeting the AAP recommendations of 200-300 words at 24 months and therefore probably has a speech delay. 4. Mummy and Daddy Pig seem to be on lithium.

Yes, fully agree with Ed. There is not now, nor has there ever been, convincing evidence that COVID-19 causes additional immune impacts beyond the acute period that make you more susceptible to future infections.

Yup, once again, @dereklowe.bsky.social in @science.org nails it: “Marty Makary, our head of the FDA, believes that Lyme disease is an escaped biowarfare agent. Jay Bhattacharya, among other things, believes that he is fit to lead the NIH. We are being governed by grinning idiots and sociopaths”

Newborn product marketing: This is the safest product ever, Your baby will love it. Newborn product disclaimer tags: BABIES HAVE DIED USING THIS PRODUCT.

Neither grok nor x apologized in any official statement. The screenshotted “apology from grok” was created by a user who prompted it to issue an apology for creating a specific CSAM image of girls who were 12-14 years old (by grok’s estimation). He prompted grok multiple times to get this “apology.”

LLMs are 100% - yes, 100% - the results of their programmer's intentions. Yes, there are some unexpected outputs. But if you'd chatbot creates sexual images of young children, either the programmers don't care or THEY EXPLICITLY WANTED IT TO DO THAT.

Good read as usual from @gidmk.bsky.social , www.theguardian.com/commentisfre...

Every week, Nature publishes yet another breathless puff piece about some AI startup, based only unpublished claims from the company and interviewing only those who work there. How can the leading scientific journal publish piece after piece that would make Kevin Roose blush? I think it's that...

Baby number 2! Gotta love the newborn snuggles.

Journal invitations to peer review over the last 2 weeks of the year: Hi! Wanna do some free work? My out of office:

I wouldn't describe Jay as "man in the middle" unless I were making sort of human centipede analogy.

After the Bondi attack, I wrote about guns and gun laws as a Jewish Australian and an expert in public health: www.theguardian.com/commentisfre...

From 4 years ago...still accurate from @gidmk.bsky.social ... never forget, when meds are made unavailable, unaffordable or demonized...#Big Supplement will be quick to attempt to fill the gap

This is a fun one. Vitamin D for Mongolian schoolchildren. The main study has been cited hundreds of times, it forms a large part of many meta-analyses showing that vitamin D reduces the incidence of respiratory infections.

One of the main problems with the entire "good guys with guns stop bad guys with guns" ethos is that there is no useful definition of either "good" or "bad" guys.

HAHAHAHAHAHAHAHA Water causes diabetes. Inject the Pepsi Max directly into my veins.

Scientific error-checking, difficulty: mixed Find some errors for me. I can see at least 3 problems, there are probably more. Tables are from an RCT with group sizes of 40 and 37 in the intervention and control groups. Bonus points for the most piratical explanation of the issues

Is saturated fat good for you? Experts say no, but the current US administration has found a partially sentient tapeworm attached to a dying warthog that disagrees.

As the Australian teen social media ban comes into effect, I think we can all finally breathe a sigh of relief that we will never have to actually know what 6 7 means.

I am not familiar enough with calcium scores to know if this is weird. Is there any biochemical reason that all of these means/SDs would end in even numbers?

My new piece looks at the science about low vitamin D levels and why the US Endocrine Society no longer uses the term "deficiency" at all. gidmk.substack.com/p/theres-no-...
