Limits and Possibilities of Metascience

Introduction Michael Nielsen and Kanjun Qiu (N-Q) recently published a lengthy essay (30k words) on meta science. Over the past year or two I have been publishing here on meta-scientific topics as well, totaling around 80k words (at this point these are more books than essays!), going into the minutiae of various foundational papers and talking points. The points I make throughout my work are sometimes rarely found elsewhere in writing though they are often discussed in person in the metascience community (…

Images and Words: AI in 2026

In a previous Links post, and in a recent tweet I expressed my relative lack of excitement about what a lot of people are doing with what I called "the AI stuff" (narrowly, large language models and diffusion models, collectively "generative AI"; excluding e.g. Tesla's FSD or AlphaFold). In an even earlier tweet, I asked Twitter if we had learned anything new from LLMs yet, as opposed to LLMs telling us what we (the internet) already knew; the conclusion being that we have not. Nostalgeb…

Blinking lights to slow down Alzheimer's?

In a post in my Alzheimer's series I discussed the not-so-promising monoclonal antibodies against amyloid beta. There are a few other therapies one could discuss, especially tau antibodies, but first I wanted to examine a particular one that has nothing to do with the most popular approaches currently on their way to the clinic. This is a relatively shallow examination of the topic, focused on the question of whether it works, and less so on how it works. That intervention is GENUS, or Gamma Entrainment Usi…

Rain is a startup that fights wildfires. They now have a second version of their system, a large unmanned drone. I was not particularly enthusiastic about that first drone, but their second iteration looks promising. I amended my wildfires post accordingly.

I didn't learn anything surprising (been following the space for years), but the piece hits some of the themes I had in mind for …

The failure of monoclonal antibody therapy for Alzheimer's Disease, implications for the Amyloid Cascade Hypothesis

In a previous post I explained the basics of Alzheimer's disease and the current state of the art in our understanding of it. I focused on the amyloid-tau story while hinting at the fact that there are other factors worth exploring. I mentioned the "repeated failures of Alzheimer's drugs in the clinic". This post is about that. I mostly focused on the Aducanumab case, with solanezumab and lecanemab as contrasts. These trials have been used as evidence against the amyloid cascade hypothesis (ACH). …
