New piece on why it’s unhelpful to characterise COVID debate as ‘lockdowns are bad’ vs ‘lockdowns are good’ when it was really about people who claimed that COVID was 100x less fatal than it was + optimal to have a massive epidemic immediately before vaccine… vs those who sense checked these claims.
Restrictions had unequal impacts, but the pandemic itself did too. - Boston Review

Thanks to @ReporterGoodman
for this excellent piece.

A team of us compiled data on controlled vaccine trials: 258 so far (~1/2 of which used inert placebo), covering 45 antigens and 2.5M participants.

Claims that vaccines lack placebo trials are false. 1/2

We just had an article published in ACS Central Science on the how the pH of exhaled aerosol evolves over time.

As we’ve previously reported, respiratory aerosol pH (high pH!) is a driver of SARS-CoV-2 decay. Meaning, understanding the pH dynamics is important for estimating risk.

Our preprint “How Malicious AI Swarms Can Threaten Democracy” is now online.

We show how coordinated multi-agent LLM swarms can infiltrate communities, craft synthetic grassroots “consensus,” and erode institutional trust—and what we can do now to stop it.

This is what a lot of us have been worried about.

This allows for many civil service positions to replaced with political appointees. This could include NIH institute directors and even POs.

Visualizing this a different way below. I pulled all the data I could from the Web Archive of the CDC Measles Cases and Outbreaks page. The week of Feb 16th is highlighted to illustrate how much data can lag. An animated GIF of this graph from week to week is here: github.com/gaddb/share/...

David Geier has apparently been commissioned by HHS secretary RFK, Jr. to study potential links between vaccination and autism.

He and his father have 2 papers in 2017/2016 claiming to show Hep-B vaccination greatly increases risk of autism/obesity.

However, their studies have FATAL FLAW...

The problem with relying on "the evidence" is that evidence needs interpretation and lots of people interpret evidence in different ways. Some interpretations are reasonable, others are very stupid, and sometimes the most stupid ones come from otherwise smart people.

There's a big difference between understanding the literature of virology and immunology and cherry-picking items that coincide with your biases.
