This week's ACIP meeting was filled with false and misleading statements that are not supported by evidence. Here's an explanation of that evidence by two experienced science writers, one of whom has a PhD in Immunology from Yale: www.factcheck.org/2025/12/vacc...

A real “Εὕρηκα!” moment in Virology. And the long, slow work before and after that moment.

The public saw a vaccine appear in under a year. Scientists saw the 20 years of prior work that made that ‘one weekend’ decision possible. The vaccine was made quickly because the science wasn’t.

I helped put Baraclude (entecavir) on the market, my employers made billions from it, & I'm still proud of that work. But I would much rather live in a world where Baraclude wasn’t needed, because babies never got Hep B in the first place. A 🧵on why this week’s ACIP meeting was so alarming.

Tis the season of the tire pressure light! And I can't find an emojji character for that...

Realtors got Zillow to hide climate risk information. Hiding a risk does not make it go away.

They just voted as I had feared they would vote. This decision is likely to kill thousands of people.

ACIP meets Dec 4–5. This is the 3rd meeting since RFK Jr. replaced the entire committee. Based on the draft agenda & recent meetings, experts expect many misleading claims about routine vaccines. I did Infectious Disease Research for decades. I am very worried about what the new ACIP might decide.

This is NOT quite how I did overcurrent testing as an electrical engineer: crazy nerd experiments with 30 KW light bulb... youtu.be/zr-eZ_pLTNI?...

How one DRESSES is not inherently moral or immoral, it's about the social conventions of one's time and place.

Reading an article about how few people live in places with dark skies, I remembered this photo I took of the July 2020 comet. I did NOT see the comet with my naked eyes: I put a camera on a tripod pointed in the right direction, and took a long exposure. A few minutes later I saw this on my screen.

You may know that measles is VERY contagious & a VERY serious disease. Image explains how measles is even worse than most people realize because it wipes out immune memory. See tinyurl.com/MDHmeasles

This ACIP meeting may represent another attack on public health that puts more children in danger.

Ryan Goodman, a New York University law professor and former Pentagon lawyer, to NY Times reporter: “Even under a law of armed conflict, they were all civilians, and we are not actually in armed conflict. Either way, it was all murder.”

In May 2020, surveys of epidemiologists showed a 90% chance U.S. COVID deaths would exceed 118,000 by year’s end, and a 10% chance they’d exceed 1.2 million. I followed these surveys closely and tried to warn others how serious the pandemic would become.

Impact of the pandemic, in the most unbiased and simple statistical presentation possible. Close study will reveal a great deal.

ACIP is about to consider weakening the long-standing recommendation that all newborns receive the Hepatitis B vaccine, but here’s a reason universal newborn Hep B vaccination has been recommended since the 1990s: it works, it’s safe, and there is no scientific basis for changing it.

Image from Wikipedia of 2025 storm tracks. 2025 storms mostly missed the U.S., so disaster response hasn’t been tested. Given the failures I have seen elsewhere, I worry: what if 2026 is just this map shifted 300 miles west?

Frances Oldham Kelsey saved lives by insisting on evidence. Her story is a reminder: if institutions sideline people like her, the failures come — just not right away. Trump has fired thousands of people like her. We might miss the next Thalidomide disaster.

The real victims are the kids whose health is at risk now. Had Nuzzi done her job as a reporter, RFK might not be in charge of public health now. See my FB for a longer take. www.nytimes.com/2025/12/02/o...

Official US Military manual on Laws Of War. Search for the phrase "hors de combat" and apply that to shooting people in the water after their vessel has been blown up and the conclusion is clear: under THE PENTAGON'S OWN OFFICIAL RULES that was a war crime. ogc.osd.mil/Portals/99/d...

Self-driving cars are much safer than human drivers. AND, a point not mentioned in this article, humans don't have to wait while one of them is recharging its batteries. www.nytimes.com/2025/12/02/o...

How Infection Fatality Rates changed, and what that means

The New York Times used 1,200 words to say what everyone already knows: we still have no idea why Trump’s doctors ordered that MRI, and the explanations so far are completely unconvincing.

An Excess Deaths Explainer: even after experts have been trying to explain this key concept for years, it still confuses many people.

I am probably on the spectrum myself.

Trump promised to end inflation. Economists said his policies would raise it. Voters on TV ask why prices aren’t falling. But even slower inflation — which isn’t happening — isn’t deflation. And real deflation usually means depression. So low-info voters may get even angrier about today’s inflation.

Code generated by an AI model is less secure if the model is given a context that is politically negative to its creators, probably not due to an explicit directive to emit bad code but as an unanticipated effect of making it biased in other contexts: www.lawfaremedia.org/article/deep...

Trump harmed coal country, Biden helped coal country but they love Trump! www.theguardian.com/environment/...

Why don't GOP noses grow longer every time they say "law and order"? Trump says he will pardon Juan Orlando Hernández, a convicted drug kingpin, even as he orders the murders of Venezuelans for alleged drug smuggling AND he cuts back drug arrests to divert law enforcement resources to deportations.

Fairness requires checking primary sources. So I checked Conservapedia and found it was just as bad as described in secondary sources.

Pomo Fragonard... POMO Rococo scene on a rooftop: a woman in an iridescent gown lounges while swiping on her phone, two friends pose for a selfie nearby, and a man overlooks a pastel city skyline under a neon “L’Air du Temps” sign.

Finally getting some theological clarity on the ethics of reclining in one’s plane seat

Meta-lessons about data, models, and AI...

I strongly agree with this post.

Phrase I just heard, I leave it to you to imagine the context: "God doesn't even know."
