Top tier mad science -- take a mouse, make it not have a cortex, put in human cortical cells, and see what happens. Seems like the mouse is mostly fine?! Huge implications for drug dev for neurological disease.
1/ I have long dreamed of systems that could causally model human neurobiology across scales, from molecular to behavioral.
In @Nature, delighted to share our efforts at creating xenocortical mice where human organoids grow to occupy most of mouse cortex.

Had a great time chatting about Ricursive at RAISE. And the organizers managed to set up a dinner for us at Versailles!
Congratulations to RAISE 2026 speakers @annadgoldie and @Azaliamirh, who were named to @TIME 100 AI 2026 last week.
The co-founders of @RicursiveAI built AlphaChip at Google, a deep reinforcement learning agent that generates superhuman chip layouts in hours rather than weeks. It's already deployed across five generations of Google's TPU, Waymo chips, Pixel phones, and Axion CPUs. And the recursive part is already running: the next generation of AlphaChip was trained on TPUs whose layouts were designed by the previous version.
At Ricursive, they're going further. Their tools run up to 1,000x faster than leading commercial tools. The vision is what they call the "designless era", where any company, from frontier AI labs to robotics startups, gets custom chips built for their specific workload without needing hundreds of chip design experts in-house.
As Anna put it at RAISE Summit: "It shouldn't take a year or more to design a chip. And it shouldn't involve hundreds or thousands of human experts."

Yay, in TIME100 AI w/ @Azaliamirh !
With AlphaChip, we started the field of AI for Chip Design.
Last year, we founded Ricursive to take on all of chip design, from model to GDS (the final input to the fab).
How we got here: (1/n)
Great to see. @davidasinclair's book Lifespan helped get me into longevity biotech in the first place.
I’m incredibly proud & excited to finally share what we’ve been building for the past 3 years…
Lifespan.com is now live 🚀
In a world of conflicting health advice, how can anyone distinguish between what’s supported by science and what’s just opinion?
I wanted to build something new. A place where scientists, engineers, industry leaders, and the public come together, where people can understand what the science actually says, and where we move healthcare beyond treating sickness toward extending healthy lifespan well beyond what’s currently possible.
Explore the new Lifespan Magazine. Watch the Lifespan show. Ask scientists questions. Join a global community. And help support research and the next generation of scientists working to extend healthy human lifespan.
I believe we’re at the beginning of a revolution in our understanding of human aging, and perhaps one day, our ability to change it. I want everyone to be part of it.
Built by scientists. Built for you. Lifespan.com
Life’s too short. Let’s change that, together! 👊

Fun conversation with Sally at EE Times - thought she did a great job capturing our vision on the future of AI for chip design!
I interviewed @RicursiveAI cofounders @annadgoldie @Azaliamirh, who led Google AlphaChip project, about their vision for an AI foundation model that can do end-to-end chip design. The startup has raised $335m but is "definitely not an EDA company":

If you want to work on the world's most important problem, this conference is the perfect on-ramp. Really enjoyed reconnecting with colleagues there last year.

Excited to announce that @Azaliamirh and I are launching @RicursiveAI, a frontier AI lab creating a recursive self-improving loop between AI and the hardware that fuels it.
Today, chip design takes 2-3 years and requires thousands of human experts. We will reduce that to weeks.
This will be incredibly hard.
For context: Go has a search space of 10^360. A simplified version of chip placement—only one part of the design process—has a search space of 10^9000.
But we are the right team to solve it.
We co-founded the Machine Learning for Systems team at Google Brain. There, we built AlphaChip—an RL agent for chip placement. AlphaChip has been used to design four generations of TPUs, data center CPUs, autonomous vehicle chips, and mobile phone chips. These chips are running in data centers and devices all over the world.
Our immediate goal is to dramatically accelerate chip design.
Next, we plan to design chips end-to-end given an ML workload, unlocking a Cambrian explosion of custom silicon.
Finally, we will close the recursive loop. We will build our own chips, train our own models, and co-evolve them on the path to superintelligence.
AI designs better chips 🔄chips train better AI
