We're at the threshold of understanding intelligence itself. The convergence of neuroscience and AI has created an unprecedented opportunity — but our research ecosystem isn't built to seize it.

We need a new model that matches the scale of our ambition... 🧵

Lots of excitement around open source computational binder design (BoltzGen FTW!), but as far as I can tell it's still ~2x more expensive per target than a traditional campaign with a CRO.

(60k runs/target) x (2 mins/run) x ($5/hr for an A100) = $10k/target

vs ~$5k with a CRO

It's increasingly tempting to believe frontier models truly understand concepts and their relationships like humans do. Then I get a figure like this from today's leading model and the illusion is ruined. <sigh>

Is there an academic/industry divide in attitudes about using AI to support discovery? I noticed this post has 3.6k likes on X but only 6 likes on Bluesky. It deserves more attention here!
Today, we're announcing Kosmos, our newest AI Scientist, available today. Kosmos makes fully autonomous scientific discoveries at scale by analyzing datasets and literature, and is the most powerful agent for science so far. Beta users estimate that Kosmos does 6 months of work in a single day.

For a decade, my white whale as a neuroscientist has been working to convince public+private funders to "go big" on post-mortem human tissue analysis, so we can define circuit disruptions in disease and just maybe link them with molecular drivers. This remains as tough a sell today as 10 years ago.

Very excited that the clinical trial results for our PRIMA retinal prosthesis are published today in the New England Journal of Medicine! This is the first time that patients who are blind due to photoreceptor loss have been able to intuitively see again.

Settle a debate for me: If you could hook up a fruit fly brain to a completely new set of end effectors, could it learn to use them for goal-directed behavior? To what extent is an insect brain evolutionarily specialized for controlling its body? #FlyBCI

There is a famine currently affecting 640k children in Sudan, driven by military action funded by a key US ally in the Middle East. It's been widely reported in the media since 2023. Yet no condemnation by public figures, no demonstrations in the US. Why does no one care?

The writing's on the wall that the future of neuroscience is team science. The key question is how to balance support for "top-down" vs "bottom-up" collaborative research efforts. I agree teams of early career researchers deserve greater agency. Thoughtful piece by @neuralreckoning.bsky.social 👇

This 👇 is a major advantage of optical circuit mapping approaches over non-destructive (i.e. non FIB) serial section EM. Fewer failure modes that prevent tracing across distinct imaging volumes.
An important addition to the Nature paper, beyond what was shown in the 2024 preprint, is 12 rounds of iterative imaging and sectioning of a LICONN volume, achieving 205 microns in axial extent (native scale) with manual tracing of axons: www.nature.com/articles/s41...

Thought problem: If you could deeply phenotype a whole brain - mapping all ultrastructure and connectivity, plus in situ proteomics, metabolomics and transcriptomics - would that be sufficient to constrain a model of its function under all conditions? What's the minimal data needed for emulation?

Gratified by today's news of a $155M seed round for DNA data storage newco Atlas, built on technologies developed under the IARPA MIST program. It validates my "if we de-risk it investors will come" thesis. Also means my public service has now driven >$1B of economic activity 🙂
