Curated weekly digest of notable AI/ML and biotech developments. Flagged items are manually selected; remaining items are the week's most recent. 🧬 Biotech ★ Human genetics across levels of biological organization — Genetic variation influences human physiology across biological scales from molecules to cells, tissues, organs and the whole organism. ★ From static structures to dynamic landscapes: cryo-EM redefines RNA biology — Recent advances in cryoEM are now transforming this landscape by enabling the visualization of RNA molecules across a broad spectrum of functionally relevant conformations at near atomic resolution (arxiv-digest, 2026-09-01) ★ Operationalizing open-ended biological discovery across single-cell representations — Projection into unseen datasets then evaluates their generalizability and phenotype association, providing a scalable screen for candidates that warrant prospective validation (arxiv-digest, 2026-09-01) ★ Learning Task-Specific Anti...

It have been quite a busy time since a recent family visiting trip. I only get a chance to read a few articles in the past week. Here is one that seems interesting. ★ Megalodon: Efficient LLM Pretraining and Inference with Unlimited Context Length — The quadratic complexity and weak length extrapolation of Transformers limits their ability to scale to long sequences, and while sub-quadratic solutions like linear attention and state space models exist, they empirically underperform Transformers in pretraining efficiency and downstream task accuracy. Another interesting article on synthetic biology, where researchers created a synthetic cell that puts user closer to building life from scratch. Here is a comment article from Science .

Curated weekly digest of notable AI/ML and biotech developments. Flagged items are manually selected; remaining items are the week's most recent. 🧬 Biotech ★ ViMax: Agentic Video Generation — Long-form video generation requires systematic narrative planning and visual consistency that current short-clip methods cannot provide. ★ Decoding intercellular activities for more than 1,000 secreted proteins ★ A light-controlled tetanus neurotoxin enables rapid and reversible synaptic inhibition in vivo ★ Alignment with experimental data improves protein generative modeling ★ Efficient evidence-based genome annotation with EviAnn — Machine-learning-based ab initio gene finders have long been central to eukaryotic genome annotation, largely because gene expression data were historically expensive and limited. ★ ClairS: a deep-learning method for long-read tumor–normal pair somatic small variant calling — Somatic variant discovery in tumors is crucial for clinical ana...

Curated weekly digest of notable AI/ML and biotech developments. Flagged items are manually selected; remaining items are the week's most recent. 🧬 Biotech ★ CAFE: A Co-folding Approach for Fragment Exploration of Allosteric and Cryptic Binding Sites — Co-folding models hold immense potential for allosteric drug discovery, but have been severely hampered by their systematic bias toward orthosteric ligand binding. ★ Decoding cancer circulating transcriptomic signatures with language models — Current liquid biopsy methods for multi-cancer detection using plasma cell-free RNA (cfRNA, short RNA fragments circulating in blood that can reflect disease states) typically rely on gene annotations, which can overlook signals from unannotated or repetitive genomic regions. ★ An expanded codebook of human transcription factor DNA-binding specificity — Abstract Gene expression is regulated by transcription factors (TFs), which recognize specific DNA sequence motifs. ★ Generat...
