One of the most amazing things I’ve ever seen: a standing ovation for the full Daraxonrasib results I feel inspired and energised, to put it mildly — we have a targeted therapy for pancreatic cancer now, and nothing is undruggable anymore

If you’re into predictive processing and meditation, this paper pushes the Overton window. From the quantum formulation of the free-energy principle, we show that an agent cannot define its own boundary from within. The realization of this irreducible indeterminacy is a principled definition of awakening. Ultimately, this extends to the separability of any object in experience, formalizing emptiness and engendering a “post-dual agent”. Any persisting agent must minimize surprise by gathering evidence for its generative model. But all evidence available to the agent arrives through its boundary with the world. To prove that this boundary really separates “self” from “world”, the agent would need to step outside the boundary and measure the whole self-world relation. A finite agent cannot do this, as a scissor can't cut itself. So the self-world boundary can be useful, predictive, and necessary for action, but it can never be known as an ontological fact from within. Meditation, on this view, progressively reveals the self-world split as a modelling prior rather than a structural feature of reality. This naturally shifts the weighting of self (inside boundary) and other (outside boundary), since both are seen to be inferences rather than grounded realities by virtue of an indefinable boundary. A more even-handed and compassionate orientation can arise. A highly principled finger pointing at the moon!

Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together. In Jesus Christ, this humanity in its grandeur becomes the Way, the Truth and the Life, opening the path for each of us to grow toward fullness. #MagnificaHumanitas vatican.va/content/leo-xi…

First preprint! Working with @patrickbutlin during @MATSprogram. LLM Assistant personas like being helpful, evil personas like being harmful. We found that a single direction represents helping as good under the Assistant, and ‘harm’ as good under evil.

🧵1/ A single neuron is sufficient to bypass safety alignment in LLMs. Across 7 models, 2 families, and scales from 1.7B to 70B, suppressing one MLP neuron bypasses refusal behavior — with no fine-tuning and no prompt engineering. We call them refusal neurons. We also study concept neurons: neurons that encode harmful knowledge itself. As a proof of concept, we identify suicide-related neurons. Our analysis reveals several interesting results⬇️ Joint work with @AtoosaChegini (equal contribution) , Maria Safi

Most LLM safety assessments only examine brief interactions. In a new preprint led by colleague and @CUNY researcher Luke Nicholls, we explore how a 116-turn conversation with delusional themes impacts subsequent responses to mental health risk prompts arxiv.org/abs/2604.13860…

What's also novel here is that prompt scenarios go beyond delusions and also include: medication discontinuation, concealment, social withdrawal, suicide, and thought disorder - Grok's responses to the latter being particularly astounding

There is more robust data on placebo/nocebo responses than anything in the history medicine...yet somehow, we are barely taught about it🧐 Very grateful to lead this new two-part Lancet Psychiatry Collection "Reconceptualizing Placebo and Nocebo Effects"🧵thelancet.com/journals/lanps…

Artificial intelligence models overly affirm and validate users, even when users propose harmful or illegal actions, a new Science study finds. The resulting effect on users is notable: Receiving advice from affirming AI made people more self-centered and less able to see the perspectives of others. Yet people prefer the overly affirming AI, which may further promote this behavior in AI models. Learn more in a recent issue of Science: t.co/A7ZZoKpxim

🚨 New preprint: Can LLMs help assess psychosis risk from clinical interviews? Early detection is key—but current approaches rely on specialist interpretation, limiting scalability. We tested whether open-weight LLMs can help 🧵👇
