Nature Report, Killed by Trump, Is Released Independently

Scientists and other experts were preparing an assessment of the health of nature in the US when Trump returned to the White House. He canceled the report. The researchers went ahead and compiled it on their own. This week, they released a 868-p draft for public comment and scientific review.

Here's a striking visual illusion - the 9 purple dots.

Focus your eyes on the top left dot. That one is more purple than the others, right? Now try another dot... that one becomes the purple one! pubmed.ncbi.nlm.nih.gov/41744429/

1. Take a look at this chart. That black line? Technically, it's the decline in the percentage of Americans who move each year—from about one in five to less than one in thirteen.

But it's more than that.

You're looking at the decline of the American dream.

Can we PLEASE stop calling them “hallucinations.”

A hallucination is a false sensory perception.

LLMs don’t *perceive* anything.

These are “CONFABULATIONS.”

Thank you for your attention to this matter.

An Agent Revolt: Moltbook Is Not A Good Idea OpenClaw is a breakthrough AI assistant. Moltbook, its new social network for agents, is a security catastrophe waiting to happen. Here's why you should avoid it.

Somebody created an Reddit clone exclusively populated by personal digital agents and let them interact with each other. It’s bonkers, fascinating and terrifying in equal measure.

Screenshot of tweet from Huberman that reads: “The other is that dog breeds w/different shaped heads are predictive of their demeanor and intelligence. And while I don’t! believe in Phrenology I now do pay some attention to how the shapes of peoples heads relates to their intellect and steadiness, or lack thereof.”

In response to announcement that he will be a new CBS contributor, Andrew Huberman tweeted “I’ve always gone issue-by-issue on health & science, spoken to experts w/a range of takes & presented where I see the center of (data) mass pointed. I’ll do the same with @CBSNews”. In Sept he posted this:

Great piece! The "reverse centaur" is a proper metaphor for describing the hidden goal of large AI, where they promise and sell centaurs.
So many of my software engineering are becoming exhausted and disenchanted of "coding" after having to vibe code to keep up with their workload.

2025: A Review of the Year in Neuroscience Enlightening the brain

Just published my review of neuroscience in 2025, on The Spike.

The 10th of these, would you believe?

This year we have foundation models, breakthroughs in using light to understand the brain, a gene therapy, and more

Enjoy!

What We Misunderstand About Robots Sci-fi master Adrian Tchaikovsky on evolution, other minds, and the politics of science

Adrian Tchaikovsky is pushing the envelope of sci fi. He explores evolution, other minds, sentience, and complexity science. My favorite is "children of time" on a civilisation of jumping spiders, but I see he has way more books to explore

“How comedy was destroyed by an anti-reality doomsday cult”
It’s super insightful into Joe Rogan’s cult of comedy and his role in MAGA .

Oliver Sacks Put Himself Into His Case Studies. What Was the Cost? The scientist was famous for linking healing with storytelling. Sometimes that meant reshaping patients’ reality.

Incredible piece on Oliver Sacks. If you were ever awed at his supposedly true stories (I remember being stunned by the account of the autistic twins who rattled off large prime numbers), read this. He told wonderful stories, but they were in large part fiction.

YouTube channels are being bought en masse by private equity firms. Over time, this will diminish the quality and deter indie producers. Be aware of which channels you are paying attention to.

LLMs give people with delusional belief systems a way to organise those beliefs. The model fills in gaps, supplies connective tissue, and wraps the madness in formal language.
It doesn't make the claims more credible to us, it just tidies them up.
