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...

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

Excited to share work with Zhidian Zhang, @milot.bsky.social, @martinsteinegger.bsky.social, and @sokrypton.org biorxiv.org/content/10.1... TLDR: We introduce MSA Pairformer, a 111M parameter protein language model that challenges the scaling paradigm in self-supervised protein language modeling🧵

Our development of machine-learned transferable coarse-grained models in now on Nat Chem! doi.org/10.1038/s415... I am so proud of my group for this work! Particularly first authors Nick Charron, Klara Bonneau, Aldo Pasos-Trejo, Andrea Guljas.

Proved that the diabolical Einstein field equations can be formulated as a well-posed initial value problem, paving the way for huge progress in mathematical general relativity that continues to this date. Goodbye, Madame Choquet-Bruhat

#Postdoc opportunity in #protein #evolution at #EPFL I can highly recommend working with Anne-Florence Bitbol! You'll bounce ideas off a world-class scientist with an awe-inspiring range of interests and a sharp mind—without sacrificing quality of life or a lake view. tinyurl.com/ProteinPostdoc

Bluesky is the place for science.

🚨 Check out DrugFlow, our new generative model for structure-based drug design. DrugFlow provides an atom-level confidence score for each designed molecule, and can adjust molecular size on the fly! Additional details in thread 🧵 #ICLR2025

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.

Back from a short and intense #NeurIPS2024. I enjoyed meeting old friends and catching up with cutting-edge research! I am proud of my team (LIAC at EPFL) with 3 spotlights out of 6 accepted workshop contributions. If you want to join the team, please apply below (deadline December 20th). #chemsky

AlphaFold3 still tends to overfit regions that AF2 multimer predicts to be disordered. Almost all disordered regions become helices in AF3.

Early December, the CASP16 Meeting was held in the Palladium resort in Punta Cana, Dominican Republic. Nick Grishin, myself, and Qian Qong presented the assessment of the monomeric structure predictions, the assembly predictions and of monomers in their oligomeric context. 1/n

Had an awesome time walking among giant ancient trees with a great group of people @neuripsconf.bsky.social. Highly recommended!

I can't begin to describe how life-changing this new project, ShellSage, has been for me over the last few weeks. ShellSage is an LLM that lives in your terminal. It can see what directory you're in, what commands you've typed, what output you got, & your previous AI Q&A's.🧵

Omg this is absolutely incredible 😻 Drew is such a legend, I use his videos in my undergrad teaching all the time, "ok now let me show you how this process realistically looks like"

Crosslinks can sometimes improve AlphaFold3 models. Crosslinking is an experimental method often used as a source of distance restraints in modeling. In AlphaFold3, instead of using restraints, crosslinks can be included as covalent ligands. Thanks to Agnieszka Obarska-Kosinska for the idea.

@torstenschwede.bsky.social @alphafold.bsky.social @capridock.bsky.social In the AF3 paper, massive sampling was shown to improve performance dramatically for antibody–antigen complexes. The AF3 server below justifiably did not sample at this scale. Are there plans to compute this baseline?

Stone conclusion by hearsay from day 1 at #CASP16 all top methods used AF3 somehow. Improvements are made by increased sampling (FFT etc), ranking of models still a challenge. Some improvement on antibodies.

New paper out in @ScienceMagazine! In 8 studies (multiple platforms, methods, time periods) we find: misinformation evokes more outrage than trustworthy news, when it does it's shared more + ppl are less likely to read before sharing. w/ @killianmcl1 @Klonick @mollycrockett 🧵👇
