what an incredible achievement and resource for retina researchers. We use it, we love it — it is a game changer for all of us who love retinal circuits. Kudos.

Meet Eyewire II: a new connectomic resource for the mouse retina. ~1 mm² of retina at nanometer resolution, with synapses and circuits of ca. 100,000 neurons, plus visual responses from the ~400 neurons shown in the video! Preprint: doi.org/10.64898/202... Data: eyewire.ai 🧠📈 🧠💻🧪 #VisionScience

Eyewire II is a great research project from @philipp.hertie.ai's lab and international collaborators! Read @janlause.bsky.social's thread to find out more👇

I’ve officially resigned as Associate Editor for Frontiers in Systems Neuroscience. It used to be a reputable journal, but became a case study in how forced automation destroys academic integrity. 👇

More than 200,000 Danish citizens have signed a petition to buy California as a response to Trump’s attempt to take Greenland. They say they will provide Californians with “rule of law, universal health care, fact-based politics, and a lifetime supply of Danish pastries.”

The numbers in this overview were pretty surprising to me - I wonder how they look for Germany... (were we also suffer from low economic mobility etc...)

If there's one empirical insight I'd want everyone to understand about American politics, it's this: America's problems are solved problems. Just not here. What would change if the US simply matched the average of 31 peer democracies? Not Denmark or Norway. Just the middle of the pack. 🧵

Screenshot of a data visualization titled “The Cost of American Exceptionalism,” subtitled “What would change if the U.S. matched the OECD average?” The page explains that each card shows how outcomes would change if the U.S. matched the average of 31 peer democracies. Below, a section labeled “Economy & Inequality” displays eight cards comparing U.S. figures to OECD averages. Highlights include: +$19K per household per year in redistributed income and +$96K in redistributed wealth if the top 1% matched OECD shares; a 71% lower CEO-to-worker pay ratio (from 354× to 101×); 50 million more workers with union coverage; 26 million more people with health insurance; $2.1 trillion saved annually in healthcare spending; $691 less per person per year in prescription drug costs; and intergenerational economic mobility being twice as high. Each card shows the U.S. value alongside the OECD average.

Interesting work on LLM memorization: Researchers were able to extract long book passages verbatim from Claude, Gemini and Grok --- sometimes almost the whole book. Curious to see how this type of result influences Copyright cases... Also see their thread with details and limitations below ⬇️

We extracted (parts of) 12 books in experiments with 4 frontier-lab, production LLMs. We prompted the LLMs with a short prefix of a book and asked them to complete the rest. For Harry Potter and the Sorcerer’s Stone, we extracted 95.8% of the book from jailbroken Claude 3.7 Sonnet.

Since Jan 1 2025, which feels like four trillion years ago, research has been shared on here 5 million whole-ass times. Bluesky recently passed 2 billion posts IN TOTAL. So 0.25% of the entire site's traffic was citations to research. That is actually massively high. Is it? Yes. Here's why.

lol. Before Stackoverflow I knew SelfHTML and R-Help. Stackoverflow et al. were so welcoming and well-designed by comparison (e.g., they would search existing posts based on the text you wrote). Meanwhile, all my current LLM prompts include stuff like "please please tell me when my premise is false"

Because international media largely seems to struggle to choose the correct wording to describe what’s happening: the US, under the self describes „peace president“, attacked another country and kidnapped its president. That is factual, no matter how bad or illegitimate Maduro‘s rule is (very bad).

Warum brauchts Journalismus von Netzpolitik.org? Nur so erfährt die Öffentlichkeit von Datenleaks und problematischen Entwicklungen in Richtung Überwachungsstaat (Palantir, Chatkontrolle..). Digitale Zukunft geht nicht ohne unabhänge Medien, die sich auskennen! Also, wer kann: Jetzt spenden!

Incredible piece on Oliver Sacks. If you were ever awed at his supposedly true stories (I remember being stunned by the account of the autistic twins who rattled off large prime numbers), read this. He told wonderful stories, but they were in large part fiction. www.newyorker.com/magazine/202...

Oliver Sacks Put Himself Into His Case Studies. What Was the Cost?

The scientist was famous for linking healing with storytelling. Sometimes that meant reshaping patients’ reality.

I'm more and more convinced that low-dimensional manifolds in the brain are just an artifact of the experimental designs and analyses we use... 🧠📈 🧪

Mick Bonner@mickbonner.bsky.social · 8mo ago

Dimensionality reduction may be the wrong approach to understanding neural representations. Our new paper shows that across human visual cortex, dimensionality is unbounded and scales with dataset size—we show this across nearly four orders of magnitude. journals.plos.org/ploscompbiol...
