Protein function often depends on protein dynamics. To design proteins that function like natural ones, how do we predict their dynamics? @HWaymentSteele and I are thrilled to share the first big, experimental datasets on protein dynamics and our new model: Dyna-1! 🧵

Extremely clever new NGS tech from Roche 🧬 If it's hard to discriminate between nucleic acids accurately with a nanopore, why not synthesize a new polymer off a DNA template that is easier to sequence? It's an intuitively simple idea, but took *a ton* of creative nucleic acid chemistry + enzyme engineering to design modified NTPs and create polymers of them. It's been very interesting to see Roche move into the NGS market, and time will tell how this stacks up with the growing set of totally orthogonal approaches people are cooking up for sequencing tech. It feels like we are entering another renaissance for biological measurement infrastructure—which is super important. “Progress depends on the interplay of techniques, discoveries, and ideas, probably in that order." - Sydney Brenner (These animations of sequencing tech will never get old to me. What a time to be a biologist!)

Reading "Distilling Knowledge in a Neural Network" left me fascinated and wondering: "If I want a small, capable model, should I distill from a more powerful model, or train from scratch?" Our distillation scaling law shows, well, it's complicated... 🧵 arxiv.org/abs/2502.08606

A major challenge for CAR therapies in GBM? The suppressive tumor microenvironment (TME). CAR-T, CAR-NK, and CAR-macrophages each struggle against it, but in different ways. Awesome work from @to123w shows why multifaceted engineering is essential for durable efficacy. 🧵👇

Balancing Locality and Reconstruction in Protein Structure Tokenizer • The AIDO.StructureTokenizer (AIDO.St) introduces a VQ-VAE-based approach for protein structure tokenization, transforming 3D structural data into discrete tokens. This tokenizer aligns sequence and structure seamlessly, enabling advanced multimodal applications. • Innovation highlight: The model strikes a critical balance between locality and globality in tokenization, enabling superior performance in both structure reconstruction and homology detection tasks compared to existing tokenizers like ProToken and Foldseek. • AIDO.St features a 300M parameter model with an equivariant encoder and an invariant decoder, trained on over 477,000 protein structures. This architecture ensures rotational and translational symmetry in encoded features. • Compared to competitors, AIDO.St achieves a 2% sacrifice in reconstruction accuracy while significantly boosting retrieval and prediction performance, outperforming ESM3 and ProToken in multiple benchmarks. • Structural reconstruction metrics, including TM-score and RMSD, show AIDO.St’s superiority, especially for proteins with larger radii. The tokenizer reconstructs structures with a TM-score of 0.986 for proteins with radii <100 Å. • AIDO.St demonstrates strong alignment with protein language models (pLMs), boosting structure prediction accuracy. It enables a sequence-to-structure pipeline with unprecedented TM-score improvements in CASP14 and CAMEO datasets. • Practical implications: This tokenizer not only advances structure prediction accuracy but also bridges sequence and structure modalities, paving the way for breakthroughs in protein modeling and drug discovery. @ericxing @dasongle @yingtaoluo @barthelemymp 💻Code: github.com/genbio-ai/AIDO 📜Paper: biorxiv.org/content/10.110… #ProteinTokenizer #3DBiology #AIInBiology #GenerativeModels
