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!

Very neat video, and equally neat housekeeping :)

💥 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 🚀

You asked and we listened... @workshopmlsb.bsky.social is excited to be expanding to Copenhagen, DK at @euripsconf.bsky.social 🎉

Two workshops (San Diego & Copenhagen) will run concurrently to support broader attendance. You can indicate your location preference(s) in the submission portal💫

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...

Is there any way, any way at all, that this can be followed remotely? (jk, but if you have a link...)

🎉 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.

📢 Our new preprint is out on bioRxiv! We introduce RAG-ESM, a retrieval-augmented framework that improves pretrained protein language models like ESM2 by making them homology-aware with minimal additional training costs.

@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"

Great to see this long-form version of your ICLR 2024 work finally out!

I wrote an op-ed on the world-class STEM research ecosystem in the United States, and how this ecosystem is now under attack on multiple fronts by the current administration: newsletter.ofthebrave.org/p/im-an-awar...
I’m an award-winning mathematician. Trump just cut my funding.
The “Mozart of Math” tried to stay out of politics. Then it came for his research.

AtomWorks is out! Building upon @biotite_python, we built a toolkit for all things biomolecules and trained RF3 with it. All open-source, test it via `pip install atomworks`!

Thanks, that makes a lot of sense!

(I.e., each antitoxin mutant is evaluated by making a single-row concatenated MSA with the fixed toxin?)
umbislupo.bsky.social
Small question about this point: here, what input MSA(s) did you use? I'm guessing it was concatenated MSAs with just one row?

From social media apps to bank loans and hiring/firing decisions to search engines and shopping sites, are you tired of living a life ruled by opaque algorithms?

Pre-order now to Take Back Control on August 5.

One could (modulo depth considerations) use the total/mean MSA perplexity of the concatenated MSAs under MSA Pairformer. The pairing with lowest MSA perplexity should be favoured?

*for all proteins (regardless of taxon or encoding location)
umbislupo.bsky.social
Ah-ha, thanks for the clarification! I am mostly wondering how much of this was unexpected and, relatedly, whether you have decided to turn this pairing mode on for all taxa (and why).
umbislupo.bsky.social
How much are you surprised by the case of 2Y69? It being a eukaryote, while I believe 3A0R is less surprising.
