We are implementing a similar policy at @arxiv.bsky.social. If there is incontrovertible evidence of LLM slop in a paper, this means the authors did not take the time to read the LLM output and we can't trust anything else in the paper. Penalty is 1 year ban from arXiv followed by...

Don't be shy to take on a little two-week side project. These five months will be the most precious three years of your academic journey.

ROCKET 🚀 inference-time optimization of AlphaFold to fit structural data is published! rdcu.be/fa9YH Since our preprint, we’ve pushed it to regimes where other methods break: low resolution, weak signal, real experimental edge cases. Here’s what we learned: 1/15

I'm excited to announce some major updates to our ProteinEBM paper with Chenxi Ou @sokrypton.org!

New OpenFold3 preview out! (OF3p2) It closes the gap to AlphaFold3 for most modalities. Most critically, we're releasing everything, including training sets & configs, making OF3p2 the only current AF3-based model that is functionally trainable & reproducible from scratch🧵1/9

On the nature of the earliest known lifeforms

Five years ago, we released FLIP. The core question was: can ML models for protein fitness prediction generalize in the ways that actually matter for protein engineering, i.e. low data, extrapolation to more mutations, out-of-distribution sequences?

New pre-print from the lab on scaling transferable implicit transfer operators to protein dynamics. Collaboration with @olewinther.bsky.social lead by @panosantoniadis.bsky.social.

Introducing The Structural History of Eukarya (SHE): The first proteome-scale phylogeny constructed entirely from 3D structure. We computed 300 trillion alignments across 1,542 species to map the tree of life. 🧵👇 (1/5)

While most AI models are trained on text and images, the Polymathic AI collaboration has something different in mind: AI trained on #physics: https://www.simonsfoundation.org/2025/12/09/these-new-ai-models-are-trained-on-physics-not-words-and-theyre-driving-discovery/ #science

New Preprint!! We show that binding entropy can be quantitatively predicted from crystallographic ensemble models, accounting for both protein conformational entropy and solvent entropy! www.biorxiv.org/content/10.6...

FoldMason is out now in @science.org. It generates accurate multiple structure alignments for thousands of protein structures in seconds. Great work by Cameron L. M. Gilchrist and @milot.bsky.social. 📄 www.science.org/doi/10.1126/... 🌐 search.foldseek.com/foldmason 💾 github.com/steineggerla...

I found the secret Pret at Heathrow Terminal 5

This was fun work and a remarkable effort across the computational and wet-lab teams! Strategies for in-silico filtering and ranking of antibody designs have been under-discussed in the literature, e.g. in most technical reports on antibody design that I've seen. Let's talk about these here! [1/n]

At Absci, we performed de novo antibody design campaigns against "zero-prior" epitopes—lacking structural data from antibody-antigen or protein-protein complexes. Model architectures, training data curation, and scoring protocols are fully described. Preprint: www.absci.com/wp-content/u...

GERMAN PRESIDENT STEINMEIER: “.. the United States has broken with the values that it helped to establish .. “.. we have now moved beyond the stage where we can lament the lack of respect for international law or the erosion of the international order; we are far beyond that, I believe.”

Recently found out about @jvkersch.bsky.social's `tmtools` github.com/jvkersch/tmt.... It works nicely! Being able to pass user-defined sequence alignments is a nice (if simple) feature that is missing from OpenStructure's own `tmtools` @torstenschwede.bsky.social.

Would you like to come to my lab for a postdoctoral position? Apply for the EPFL AI Centre fellowship: epfl.ch/research/fun.... FYI, I have funding (ERC & Simon's collaboration) also for 1-2 top candidates who will not secure the fellowship. Same for @krzakalaf.bsky.social lab.

💥 We are *also* organizing Machine Learning for Structural Biology @ EurIPS, Copenhagen!! Topics include anything in the ML+bio intersection. Submit your ML+bio short papers! Authors can even present in both locations if they have people in both locations 🚀

Cool-looking work by @piompons.bsky.social @albecazzaniga.bsky.social @fra-cutu.bsky.social, going beyond existing works on sampling different conformational ensembles with AF2.

Recently tested some de-novo minibinders against two targets (thanks Adaptyv!) designed using our open-source design library, `mosaic`; our best method got hit rates of 7/10 and 8/10 and affinities as low as single-digit nanomolar. Wrote up some thoughts here: blog.escalante.bio/minibinder-d...

Two exciting openings with us! 🤖🧬🆎🧫💉 - AI Scientist 👉 lnkd.in/eDXHH4E8 - AI Scientist, Drug Creation 👉 lnkd.in/eEvGyaTR You'll work on antibody sequence/structure design, antibody-antigen co-folding, antibody-antigen binding prediction, physics-based methodologies, and more! DMs welcome!

🎉 Excited to share that the last paper of my PhD is now published in PRX Life! We introduce RAG-ESM, a retrieval-augmented framework that makes pretrained protein language models (like ESM2) homology-aware with minimal training cost. 📄 Paper: journals.aps.org/prxlife/abst...

@cyrilmalbranke.bsky.social is 🦋! "ProteomeLM significantly outperforms DCA in recovering experimentally validated interactions. In H. sapiens, ProteomeLM achieves an AUC of 0.83, compared to 0.73 for DCA. Among the top 10 million scored pairs, it recovers 50% of known PPI, versus only 20% for DCA"

A no-miss opportunity to join EPFL. We are a vibrant (had to use it 😉) community working in all branches of basic sciences and engineering, and interdisciplinary studies are strongly encouraged. If you want more information, contact the committee heads, or feel free to DM me. tinyurl.com/bd27ky7p

Thank you @seanmcarroll.bsky.social: x.com/seanmcarroll.... This has an effect. People want to keep hearing from you and they too will migrate here.

Dear US colleagues, In response to the Trump administration, my university @univ-amu.fr is setting up a new program dedicated to welcoming American scientists wishing to pursue their work in France. There are several M$ in the budget. www.univ-amu.fr/en/public/ac...

Hello American friends here. Please consider making gigantic protests great again. This platform is too small. A centralized app for coordination seems a good idea to me.

Excited to share PoET-2, our next breakthrough in protein language modeling. It represents a fundamental shift in how AI learns from evolutionary sequences. 🧵 1/13

Can we learn protein biology from a language model? In new work led by @liambai.bsky.social and me, we explore how sparse autoencoders can help us understand biology—going from mechanistic interpretability to mechanistic biology.
