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.

Finally, a call to the neuroscience community: the BID is the perfect tool to study low-dimensional dynamics directly at the level of spikes in both spiking network models and data. Feel free to get in touch if you're interested in collaborating. N/N

We look forward to applying this approach to study intrinsic dimension in non-equilibrium systems and neural representations in quantized neural networks. 4/N

We find that the BID scales sublinearly in the spin-glass phase, with changes of scaling exponents sitting at phase transitions. 3/N

We directly link the BID estimator for the intrinsic dimensionality of the spin dynamics to the overlap distribution in finite-size systems. 2/N

Not despondent to share our new work arxiv.org/abs/2601.17427 with Santiago Acevedo and Cristopher Erazo from SISSA, where we show that Binary Intrisic Dimension (BID) [ nature.com/articles/s42... ] is able to detect phase transitions in the Hopfield model. 1/N

Just got back from a great summer school at Sapienza University sites.google.com/view/math-hi... where I gave a short course on Dynamics and Learning in RNNs. I compiled a (very biased) list of recommended readings on the subject, for anyone interested: aleingrosso.github.io/_pages/2025_...

With all the sad developments in the US - go study in the Netherlands: relatively low tuition (and adequate job search visa after graduating) for high-quality programs like this one in Neurophysics or Cognitive Neuroscience at the neuroscience Donders hub

Fantastic. Congrats Will.

Statistical Mechanics of Transfer Learning in Fully Connected Networks in the Proportional Limit Tools from spin glass theory such as the replica method help explain the efficacy of transfer learning.

Our paper on the statistical mechanics of transfer learning is now published in PRL. Franz-Parisi meets Kernel Renormalization in this nice collaboration with friends in Bologna (F. Gerace) and Parma (P. Rodondo, R. Pacelli).
