Great guest post at @dailynous.com (Full disclosure: one of the authors is a former student whom I admire greatly.) One of the many ways in which academia systematically excludes people from the Global South is by hosting prestigious events only in rich countries-> dailynous.com/2026/03/10/h...

Please circulate widely! Open positions at the Vision Lab, Centre for Neuroscience, Indian Institute of Science (IISc) sites.google.com/site/visionl... How to Apply: forms.gle/vWa1PwUrcpWf... Deadline : March 31 2026

Like many things about AI, this mainly reveals and amplifies an existing quirk of the system. Professors are supposed to both do the best research (and as much of it and as fast as possible) while also working nearly 100% with trainees, whose growth & interests need to be prioritized.

To my colleagues: as you review the next round of applications, please take into account the unique challenges these candidates have faced. I’m personally witnessing how hard they strive to stay connected despite the brutality of the regime and a devastating war.

This year, I had the privilege of mentoring four highly motivated Iranian students through #Neuromatch. Despite the challenges of war, unstable internet, and disrupted research, we tried to continue our project together.

Today I received a note from a grad student who lives in Tehran. Her note gives you firsthand experience of what it’s like to live in a city that is being bombed, and what it’s like to be young and feel despair about your future. rezashadmehr.blogspot.com/2026/03/hope...

Sharing “Neural Thickets”. We find: In large models, the neighborhood around pretrained weights can become dense with task-improving solutions. In this regime, post-training can be easy; even random guessing works Paper: arxiv.org/abs/2603.12228 Web: thickets.mit.edu 1/

Nice work by Lauren Aulet showing that counting training flips an architectural area bias into a strong number bias in ResNeXt-50.

Are you a neuroscientist with great coding skills, or a software engineer interested in the brain? We are recruiting for a research software engineer to help us build pipelines to process weeks of neural and behavioural recordings from freely moving animals. More details: bit.ly/rse-2026a

The Per2Con group at CIMeC is actively seeking Post-Docs interested in investigating how newborns 👶 🧒 perceive 👁️👂and learn, using 🧠 HD EEG and eye-tracking. ✨You are motivated to work on neurodevelopment: we would love to hear from you to prepare a grant proposal together (Marie-Curie, Fyssen...)

The strongest version of this illusion I’ve seen! Absolute head-wrecker!

The "publish or perish" culture must perish. Scientists need time to think. We just published our Slow Science Manifesto, where we argue that huge changes are needed in the way we fund, publish, and evaluate science. Read more and sign here: www.slow-science.com

Neuroscientists at @flatironinstitute.org are using #neurobiology to enhance artificial systems with a new type of computational component more akin to those found in real brains: https://www.simonsfoundation.org/biological-brains-inspire-a-new-building-block-for-artificial-neural-networks/ #science

Very excited for our second workshop on the computational ingredients of reasoning (Feb 24-27), this one focused on mechanisms of reasoning in both AI and the brain. Check out the program to see our amazing lineup of speakers, and please consider attending! ivado.ca/en/events/me...

Excited to launch Principia, a nonprofit research organisation at the intersection of deep learning theory and AI safety. Our goal is to develop theory for modern machine learning systems that can help us understand complex network behaviors, including those critical for AI safety and alignment. 1

Thrilled to finally share this work! 🧠🔊 Using a new reinforcement-free task we show mice (like humans) extract abstract structure from sound (unsupervised) & dCA1 is causally required by building factorised, orthogonal subspaces of abstract rules. Led by Dammy Onih! www.biorxiv.org/content/10.6...

Again, I'm looking for a lab research coordinator to work on the developmental cognitive neuroscience of numeracy in preschoolers. Please pass on to those that might be interested publish.illinois.edu/danielchyde/...

"The academic structure … makes planning for a family feel like an impossible luxury." In this #ScienceWorkingLife, two postdocs share how, as women in academia, having children can feel impossible—and how talking about it makes them feel less alone. https://scim.ag/46uBWgD #WomenInScienceDay

Postdoc position in Paris: come help develop new generation human brain computer interfaces ⚡🧠💻 Interested? Contact me if you have experience with machine learning (e.g. simulation-based inference, RL, generative/diffusion models) or dynamical systems. See below for + details and retweet 🙏

For the past 3 years, I've taught a course on Machine Learning for Climate Change to undergrads. At times, people have asked if the course lectures could be made available online. While I can't offer that, I have decided to start making "5 Minute Papers on AI for the Planet" videos. Hope its useful!

It isn't easy following science as a career path. Our series of personal essays, published on the last page of Science, aim to shed light on the challenges scientists face and, hopefully, help others feel less alone. Here are @science.org's top essays of the year. www.science.org/content/arti...

Excited to announce a new book telling the story of mathematical approaches to studying the mind, from the origins of cognitive science to modern AI! The Laws of Thought will be published in February and is available for pre-order now.

If you analyse time-resolved data (M/EEG, iEEG, pupillometry, force recordings…) and feel limited by cluster-based permutation tests (CBPTs); especially when trying to determine when an effect starts or ends; you may want to try our new R package: lnalborczyk.github.io/neurogam/ #rstats #brms #EEG

Prediction: task-based optimization will ultimately prove to have a relatively minor role in DNN models of the ventral stream. Although tasks (including self-supervised ones) are currently crucial, there are signs that a simpler approach is possible. A thread:

“Why AGI Will Not Happen” by Tim Dettmers. timdettmers.com/2025/12/10/w... This essay is worth reading. Discusses diminishing returns (and risks) of scaling. The contrast between West and East: “Winner takes all” approach of building the biggest thing vs a long-term focus on practicality.

Excited to announce our symposium on how AI and humans shape each other “Humans and Artificial Minds: Mutual Influences” 9 Jan at ENS Paris. Talks by @smfleming.bsky.social, Valeria Giardino, Silvia Tulli, @thecharleywu.bsky.social, Laurence Devillers & @summerfieldlab.bsky.social . Program ↓

We recently stumbled upon a surprisingly common misunderstanding in computing noise ceilings that can be quite consequential. So if you care about noise ceilings, please check out Sander’s thread and our preprint! 👇

New today in @Nature: your visual cortex contains touch-based body maps. bit.ly/VisualBodyMaps Your brain transforms what you see into first-person, body-referenced codes: A previously unknown bridge between vision and touch.

New work with @simyciri.bsky.social. Adults make more accurate decisions than adolescents—yet show more intrusion from irrelevant players. We explain this paradox via efficient information compression: adults rely on combinatorial social basis functions that use group structure as a mental scaffold.

Y’all are reading this paper in the wrong way. We love to trash dominant hypothesis, but we need to look for evidence against the manifold hypothesis elsewhere: This elegant work doesn't show neural dynamics are high D, nor that we should stop using PCA It’s quite the opposite! (thread)
