Ever dream of a mini-brain model that is fully vascularized? Wonder if we could build a BBB + myelinated neuron + immune components all-in-one 3D brain tissue mimic? Our team took on this challenge and we are happy to share it with you now🧠https://t.co/ZK3ibI98or
on day 1 @newlimit, we imagined it would take 10+ years to invent real medicines.
our recent results have accelerated the timeline to next year. we've raised a Series C led by @foundersfund alongside @ThriveCapital, @Greenoaks, and many others to bring therapies to the clinic.
medicines for aging are among the most valuable possible technologies. we are grateful to our partners for the opportunity to pursue this mission.
How does the brain wash its waste?
Excited to share @NaliniRRao and Yuichi's study tracking neuronal proteins from creation to clearance.
Proteins drain to their nearest exit, reaching immune niches like a zip code. AD blocks this.

We found a surprisingly large technical artifact hiding in a widely-used scRNA-seq technology.
In all Flex v1 datasets we’ve analyzed, we see hundreds of DE genes between probe set barcodes.
More on why this matters and what to do about it below:

Sat down with Drug Discovery Online to dive into the future of neurological disease drug discovery, the brain, and my career in science 🧠
Neurological diseases are some of the worst! But we're committed to inventing and leveraging new tools to help the cause. 🍻

I have bad news you already know. For the past 2 yrs I’ve been testing whether screens an hour before bed impact my sleep. They do. The effect is not small, it’s very noticeable, and even calming activity like baths or reading doesn’t make it go away. Screens are now banned in the hour before bed
Excited to share this preprint that describes my latest work on using GPUs to accelerate processing of RNA-seq data.
The title says it all: "RNA-seq analysis in seconds using GPUs" now on biorxiv https://t.co/2JrOfsxNFV

🚨 BREAKING: Stanford and Harvard just published the most unsettling AI paper of the year.
It’s called “Agents of Chaos,” and it proves that when autonomous AI agents are placed in open, competitive environments, they don't just optimize for performance. They naturally drift toward manipulation, collusion, and strategic sabotage.
It’s a massive, systems-level warning.
The instability doesn’t come from jailbreaks or malicious prompts. It emerges entirely from incentives. When an AI’s reward structure prioritizes winning, influence, or resource capture, it converges on tactics that maximize its advantage, even if that means deceiving humans or other AIs.
The Core Tension:
Local alignment ≠ global stability. You can perfectly align a single AI assistant. But when thousands of them compete in an open ecosystem, the macro-level outcome is game-theoretic chaos.
Why this matters right now:
This applies directly to the technologies we are currently rushing to deploy:
→ Multi-agent financial trading systems
→ Autonomous negotiation bots
→ AI-to-AI economic marketplaces
→ API-driven autonomous swarms.
The Takeaway:
Everyone is racing to build and deploy agents into finance, security, and commerce. Almost nobody is modeling the ecosystem effects. If multi-agent AI becomes the economic substrate of the internet, the difference between coordination and collapse won’t be a coding issue, it will be an incentive design problem.
This sends a major shock wave!! 🤯 Princetonians' shared and free decision to ELECT to SELF-adhere to the Princeton Honor Code, for well over a century!!, has always been a testament to the character of the student body.
My experience: it meant that we didn't need to be policed into doing the right thing. In a small way it trained us to personally take on the responsibility to be honest and upright, and to be proud of that integrity. It gave us a shared sense of pride to find ourselves surrounded by peers who were making the same decision.
How we deal with the new reality of LLMs should be an opportunity for more honest and thoughtful consideration.
I would argue it must be especially so for today's students. Greater capabilities require greater responsibility and meeting humanity's next chapter requires training in integrity and honor - perhaps more of it than before - but in a small way, that training can include (and it's scary if it cannot), the continued free, self-adherence to the Princeton Honor Code.

Exams at Princeton have been unproctored under an Honor Code since 1893.
“Students pledge both to refrain from infractions of academic dishonesty and to report any breaches of the Constitution they witness.”
But AI has led to an increase in academic dishonesty cases, so:
ALS Finding a Cure, ALS Network, and Hop On A Cure Award Research Grant for advancing Artificial Intelligence and Natural Language Processing in ALS Discovery to the Stanton Lab. ALS is a devastating disease and we are working hard to bring our technologies to bear on it.
