Today in @Nature, we report a new approach to studying human brain development and modeling disease in vivo. Human neural #assembloids and #organoids have opened new ways to study development in vitro, but they also have important limitations. Transplantation can provide a more physiological environment, yet human cortical cells then develop within a rodent brain that matures much faster, constraining their growth and integration. To address some of these limitations and obtain more advanced functional readouts relevant to disease biology, we generated #apallial mice, in which ~98% of the cortex and hippocampus fail to form, creating space for transplanted human cortical organoids to grow and integrate extensively. We call these #xenocortical mice (XCX). Nearly 7 years in the making. Congratulations to an extraordinary team and wonderful collaborators! Link to the article below 👇

Lol! 😅
Scientists mapped 166,000+ neurons in a fruit fly’s nervous system. I saw a dress. Cascading neural train, a sculpted corset, and orbit-like hips. My avant-garde muse has a 30-day lifespan and lives on a banana.

When the Valley of Death is due to regulations. Super fascinating article by @NikoMcCarty on why microbes have not eaten the world!
New essay: There is a little-known regulation that has been strangling biotech innovation for decades. Engineered microbes that eat plastic, sense landmines, or destroy toxins? None are likely to be approved soon, even if proven safe and effective. This regulation, called the Toxic Substances Control Act, is a black hole: between 1987 and 2018, researchers filed more than 240 applications to release engineered microbes outside of the laboratory, such as to clean up oil spills or degrade plastic. Only a few have ever been approved for use. (Interestingly, the Act itself, as passed by Congress, doesn’t even mention biology! It was designed to regulate chemicals, and bureaucrats only later clumped biology into it.) Without reform, many of the world’s most useful microbes will never find use outside of the laboratory, even if they are proven safe and effective. Here's one example: In 2016, for example, Japanese researchers discovered a microbe that is able to digest PET, the plastic in water bottles and most polyester clothing. These wild microbes had taken an existing protein that degrades cutin (the waxy material on plant leaves) and evolved it to eat plastic instead. But natural forms of the PET-eating enzymes are slow; when the microbes were cultured on top of a thin PET film and incubated at 30 degrees centigrade, it took them six weeks to break it down. Engineers in Texas, then, took these PET-eating enzymes and used computational tools to make an improved variant, called FAST-PETase. This enzyme is 98 percent identical to the natural version but digests PET plastics in less than 24 hours. They could put FAST-PETase back into living cells and release them onto landfills. But unfortunately, such an organism would likely be rejected by regulators. Read more: worksinprogress.co/issue/all…

For the first time, scientists have mapped the complete brain and central nervous system of an adult male fruit fly — a key model organism in science. 🪰 Working alongside HHMI Janelia Research Campus and the scientific community, @GoogleResearch scientists and researchers used AI to combine millions of 2D images into 3D neural shapes, reconstructing a record-breaking 166,000+ neurons. This foundational map of the adult male fruit fly brain can help accelerate our understanding of the brain, and is a major milestone in neuroscience.

the single thing that would most accelerate our work at @ScienceCorp_ is a connectome the mouse is probably only ~$300M away, something highly worth funding
Introducing a complete map of the male fruit fly brain and central nervous system, created in partnership with @HHMIJanelia. With over 166,000 neurons, this is the largest cellular brain map to date. Learn more: goo.gle/4qQTtIW

Forest Neurotech is now Arbor Neuroscience! I couldn't imagine a better scientist and leader than Flip Sabes (CEO, @PhilipSabes) to unlock the mysteries of brain stimulation with Arbor behind him. Congrats to Flip and @WhitneySGriggs. Massive props also to @Convergent_FROs (s/o @AGamick and @AdamMarblestone) for continuing to support the Arbor team as a Focused Research Organization/FRO!
Brain stimulation can work remarkably well for treating brain disease. But we can't predict who it helps, or say why it fails for everyone else. We're building the instruments, data, and models to make neuromodulation predictable. arborneuroscience.org/introd…

The defiant teenage years are programmed in our neuro circuits!
Stanford researchers scanned teenagers listening to their mothers, having already shown that in young children her voice lights up half the brain. Something had switched. In children under about twelve, the reward circuitry fires harder for their mother's voice than for a stranger's. In adolescents it flips. The reward regions respond more strongly to unfamiliar voices, and her voice stops being the sound the system reaches for. The crossover happens somewhere between thirteen and fourteen. Nothing has gone wrong. The circuitry has not broken and she has not been demoted. It is being retuned deliberately, because a person who is going to leave home needs to start finding other people interesting, and the brain arranges that by making everyone outside the house more rewarding to listen to. Which means the thing every mother of a teenager describes has a mechanism. He is not ignoring her out of contempt. Her voice is no longer arriving at the part of him that used to light up for it. Two things worth holding onto here. The first is that the hearing and processing regions are still there and still working. He hears her perfectly. What changed is what his reward system does with the sound. The second is that this is temporary, and there is a whole literature on adult children and their mothers to say so. The circuitry is being repointed outward for the years he needs to build a life away from her. It is not being deleted. So a woman finds herself talking to somebody who used to run toward her voice across a car park, and who now barely registers it. That is her son's brain doing exactly what it is supposed to do, on schedule, and it is a horrible thing to be on the receiving end of. jneurosci.org/content/42/20/…

Convergent is one of the few places that can incubate organizations behind transformational science: - @E11BIO -- brain connectomics - @ForestNeurotech -- full brain API that became Merge Labs ($250M investment) - @leanprover -- formal mathematics Now it’s applying that model to AI resilience. Deeply needed.
We're hiring. Think: Sr partner at a venture incubator, but the outputs are Focused Research Organizations Form the thesis, find the founders, build the boards, launch the org AI resilience: bioresilience, cyber-physical systems, epistemic infrastructure, compute governance

New episode with @AdamMarblestone, CEO and co-founder of @Convergent_FROs. Adam is an extraordinary catalyst and accelerant for science: he has influenced or routed billions in funding, he helped start significant companies and scientific subfields, and he is the world’s go-to person for neuroscience roadmapping. This year, the NSF launched a $1.5B X-Labs initiative inspired by the FRO model Adam pioneered. Though he started with neuroscience, today he helps organize scientific endeavors across many fields, including AI, math, biology, climate, astrophysics, and more. Adam proposes that fields like neurotech, whole-brain emulation, cryo, and nanotech are severely limited by capital and coordination — not ideas. Connectomics is a clear case. He argues that mapping the brain's full wiring diagram is the approach most poised-to-scale and still extremely neglected. Costs for a molecularly annotated mouse connectome have come down orders of magnitude, from an estimated $10B to $100M–200M, Adam suggests, with a human connectome perhaps costing around $1B–2B. The cost curve of connectomes is similar to transistors and gene sequencing: once it is low enough, we get extraordinary outcomes for humanity. Near-term applications could pay for it: new drug targets for brain disease, insights for AI development, emulations, and even “control knobs” for mood and focus we haven’t identified yet. In this episode, we go deep on many topics in neurotech and beyond: what the brain can do that computers still can't; what neuroscience could teach AI; how you'd actually map a whole mammal brain; how far today's fly-brain simulations really get toward an upload; what it would take to move mind uploading beyond the fringe or science; where brain-computer interfaces go next; nanotech, reversible cryonics, AI doing its own ML research, and even predictive, agent-based economics. I'm very excited to have Adam on the podcast. Hope you enjoy! Other links to this episode and references below.
