more evidence that homeostasis is actively gardened by macrophages
Thrilled to share our latest work, out in @SciImmunology! We show that tissues match their #macrophage numbers to #mitochondrial_activity , ensuring efficient #waste_clearance and #tissue_fitness . A tour de force by Laura Pena-Couso, in collab with @andrsHidalgo16 & Pura Muñoz🧵

reading this thread immediately brought to mind the 2-feature stable circuit experiments by Medzhitov and Alon for CSF1R/PDGFR crosstalk between macrophages and fibroblasts and sure enough that's cited here, ref 52

true that cancer has richer deeper datasets than a lot of other conditions! however has a few major curveballs with missing data in: + longitudinal datasets w treatment & outcome annotations + precancer and postcancer serum + measures of predictive validity in preclinical models
I disagree with Dario on most things, but this is spot on: “At this point, saying that AI will cure cancer is more a cliché than it is inspiring, and most people think it is deceptive. The thing that will work is actually curing cancer.” The thing that frustrates me is that some people often draw a straight line from smarter models → cures, without acknowledging how much infrastructure is missing in between. We’ve still got a lot of work to do, people. The regulatory bottleneck gets a lot of attention. But the bigger bottleneck may be that in many places, we’re lacking the right biological data. AI can’t reason its way to cures if we haven’t generated the data required to understand the disease in the first place. Ironically, that’s why I’m most bullish on AI making dramatic progress in cancer first: decades of investment have produced extraordinary datasets across genomics, pathology, imaging, clinical outcomes, and more. For complex chronic diseases, much of that infrastructure simply doesn’t exist yet. The good news is that many companies (including @ChronicleBioAI) are racing to build it. But model intelligence and biological infrastructure are going to have to scale together. I really do believe AI can cure all diseases but only if we build the infrastructure to translate intelligence into cures at the same pace that models improve (which is a high bar!). Otherwise, we risk having superintelligent AI with an incomplete picture of human biology, and delay that promise by years.

repeating this "AI will cure cancer" argument for 18 months without any plan beyond "datacenter of geniuses" is really not great, not for AI, not for cancer research, not for patients heard it so much at NeurIPS 2025 that I wrote a roadmap for it: alexanderhonkala.com/posts/e…
Replying to @DarioAmodei
2/2 Second, on the messaging around AI.  I do not agree that my messaging has been disproportionately negative.  In fact it has been about equally balanced between risks and benefits: I’ve written one major essay about each, and even in interviews where I discuss the risks, I make sure to frequently mention the incredible benefits as well as proposing possible solutions to the risks (short clips from my interviews that end up on social media tend to be disproportionately negative, as that gets clicks).  In fact, I wrote Machines of Loving Grace because I didn’t feel the AI industry was painting an inspiring enough picture of how the technology could radically transform the world for the better.  The bulk of the essay is devoted to refuting skepticism of AI’s potential in health and biology, and showing why I think it will actually be possible to cure most human disease in ~5-10 years, as crazy as it may sound to ordinary people and frankly to biologists as well (I used to be one!).  And, if you read my most recent essay (Policy on the AI Exponential), I discuss concrete proposals for how to streamline the FDA process to make sure the deluge of AI-accelerated drugs isn’t slowed down by the regulatory process.  I feel the urgency here: I lost my father to Hepatitis C only a few years before the development of direct-acting antivirals (sofosbuvir), which cure 95% of patients and probably would have cured him. I do agree that the public has a negative view of AI (and that this is a big problem), but I don’t think it is primarily caused by me or any other AI leader warning about AI’s risks.  I think it is fundamentally a crisis of trust.  I think that ordinary people don’t trust companies, governments, or the tech industry and always suspect that we are cooking up some new way to screw them over.  The causes of this go back decades and AI is just the latest iteration of it.  I don’t think that a glitzy marketing campaign with a positive spin (which some have advocated that Anthropic do) is the way to win back that trust — at this point, saying that AI will cure cancer is more a cliche than it is inspiring, and most people think it is deceptive.  The thing that will work is *actually curing cancer*.  I think by far the most accurate criticism of AI companies including Anthropic is that we haven’t yet delivered on our big promises to benefit the world.  That is totally on us, and I think it’s the criticism you should be making, instead of all this stuff about messaging and marketing. We are however doing our best to fix this: Anthropic is ramping up its efforts very quickly in biology and medicine, and we hope to have incredible results in the coming years and some early glimmers in the coming months.  When we’ve actually accomplished something real, the whole world will hear about it, as loudly as possible, you have my word on that.  But until then I don’t want to make empty promises, and in the meantime I feel compelled to speak honestly about the very real risks of AI and how to address them.  Honesty is the right thing on the merits, and in terms of public credibility and trust it is no worse than, and may in fact be better than, an approach that ignores or distracts from risks which people instinctively understand are real.

less interesting to hope that superheating a pile of data in 10 agentic harnesses prints money than it is to ask how sufficiently motivated ppl armed with the glue- and busywork-decimating forces of emerging LLMs can *unbundle* the structural features that the cartels depend on

no despair allowed as Anthropic & others vaporize LLM wrapper startups in AIxBio, no, categorically not allowed! instead: raise your ambitions, get weirder, fly higher we're so so so so so so early

Quick thoughts on pharmacodynamic response envelopes and how detangling their components can get us better insight into drug development: alexanderhonkala.com/post.ht…

finally got a chance to read this and the logistics base of 2000 target-to-Phase-2 projects is immense on preclinical & cGMP alone, daunting to think through sam-rodriques.com/post/the-h… but pushing for fast Phase 0 trials for PD target engagement may help

heard the phrase "use AI to cure cancer!" a lot at NeurIPS this year and it bothered me, so I wrote about it: alexanderhonkala.com/post.ht…

Hi, I’m David Brückner @d_brueckner. I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information. nitter.gq/EpiMechFC/status/18254…

this is why I really want a home mass spec appliance: ppl deserve to be able to get good data about chemical composition and exposures in products & built environments *that does not depend* on the largesse of mfgrs in order to make informed choices about their exposures
There’s an emerging cross-partisan consensus on individually contentious topics — that we need to re-evaluate the advances brought by post-WW2 materials and chemical engineering now that we have a much better understanding of human biology and environmental processes.

anyone seen a good ref for the technical approaches being explored for overcoming the GvHD issues of allogeneic cell therapies, ideally w a breakdown of what's happened clinically so far?
