In languages with a grammatical gender, do AIs have a gender? For example, in French is it "le ChatGPT" or "la ChatGPT"?

The brain is the stupidest object in the universe. Every misunderstanding and bad idea in history came from a brain. Before brains, no one was wrong about anything.

If you say ANYTHING with your vocal cords, you NEED to get Broca's Area. I talk pretty much all day every day and Broca's Area makes my talking better. It actually is... correcting everything as I'm saying it.

Vaccines are off the hook for the autism caper. They've got Tylenol in custody now. Did vaccines point the finger at Tylenol to save their own skin? Are vaccines a snitch?😡

Sensory neurons drive pancreatic cancer progression through neuron-cancer pseudo-synapses pubmed.ncbi.nlm.nih.gov/41005304/ "Hello, is this pancreas?" "Pancreas can't come to the phone right now. This is cancer." ☹️

If the great psychologist Roger Shepard were still with us, he might not have been surprised by this. He proposed a helix model for auditory pitch perception, with one octave per turn. There is something very human about this finding. It's like catching an LLM counting on its fingers.

Grid cells are "more like a hash function than a global map or metric" www.biorxiv.org/content/10.1... Grid cell representation is ideally set up to decorrelate and assign easily distinguishable labels to inputs

A thousand sci-fi body horror stories writing themselves in my mind as I read this abstract

Neuron-to-cancer neurotransmission: lung cancer cells "can form functional synapses and receive synaptic transmission" from neurons pubmed.ncbi.nlm.nih.gov/40931078/ This is creepy

The first children born after the introduction of ChatGPT will be 3 years old in a couple of months. I wonder what children who grow up interacting with LLMs will make of them? Will their intuitions about questions like "are AIs alive" differ from those of us old people?

Many years ago, I was an #autism researcher, and here's a question I've been pondering for a while: Why was autism discovered when it was? Autism was, at the earliest, described in 1925 (Sukhareva) or 1940s (Kanner/Asperger) but presumably it always existed. So why wasn't it recognized before?

A study on female soccer players has been retracted due to "lack of voluntary informed consent" and "excessive physical burden and harm imposed on the participants" pmc.ncbi.nlm.nih.gov/articles/PMC... 😧

What is the relation between mind and brain? The mind is like the brain's online persona. The mind is all intelligent and mysterious, but in real life it's just a blob of neurons living in a cramped skull.

Heh, I just noticed a stupid habit of mine and figured out why I do it: because I’m stupid

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

What makes a fact a "scientific fact" as opposed to just a fact? For example, is "most dinosaurs went extinct 66 million years ago" a *scientific* fact? I think most people would say so. But why is that statement any more scientific than "the USA was founded in 1776", which is history not science?

Warning: AI chatbots will soon dominate psychotherapy pubmed.ncbi.nlm.nih.gov/40831348/ Hmm, but people value face-to-face conversation over text chats. When you can video call ChatGPT as easily as you can chat with it now, *that*'s when therapists will be in real trouble.

Here's one for data sleuths. A paper was just retracted, due to anomalies in Fig 1 and 3. But I think Fig 2 is also wack www.pnas.org/doi/10.1073/... This survival plot shows 7 groups of mice. We see big differences between some groups, but very regular death rates within groups. Probably made up?

Most people are overconfident even in the face of extensive, objective performance feedback: "Overconfidence persists in tournament chess, a real-world information environment that should be inhospitable to it." pubmed.ncbi.nlm.nih.gov/40808249/

The #arseniclife paper has finally been retracted, 15 years later www.science.org/doi/10.1126/... 2010 was a golden age of scientific social media, and #arseniclife was one of the all-time classics. I can't believe it's been 15 years!

I was going through my open tabs and realized I forgot to highlight this great News & Views in @nature.com by John List and Andrew Simon discussing @standehaene.bsky.social et al's paper showing that a gender gap in math arises soon after children begin school 🧪 www.nature.com/articles/d41...

You've heard of vibe coding, how about vibe neuroscience? I asked ChatGPT for a "labelled image of the human brain showing the function of different regions". It's "vibe accurate"!

Musk says Grok chatbot was 'manipulated' into praising Hitler www.bbc.co.uk/news/article... The anthropomorphization of AI continues. Up next we'll be hearing that yes the AI said it, but they have since grown, and now deeply regret it.

Neuroscience is more romantic than you might think. Did you know that the brain's thalamus is named after the Greek θάλαμος, which means 'inner chamber' with particular connotations of 'bridal chamber'?

I'm old enough to remember when all the edgy tech nerds were atheist.

Here's a spicy preprint - "how U.S. Republican and Democrat users express distress" differently in online mental health communities arxiv.org/pdf/2506.20377

I'm getting less and less comfortable with AI search results. Search engines used to be tools for finding web pages: they connected people. Search was also great at answering questions, but that was a side effect. With AI results, you just get answers. The original purpose of connection is lost.

For people who accept the Bayesian brain hypothesis - do you think *all* brain functions are Bayesian? So for example, is the respiratory centre that controls breathing Bayesian? Or is it better thought of as a hardwired 'circuit'?

Contrary to some pessimistic views, Bayesian decision parameters *can* be recovered from behavioural data in many cases, this preprint says www.biorxiv.org/content/10.1... "We're so back" - Thomas Bayes
