Papers

1. Digital twins of ex vivo human lungs enable accurate and personalized evaluation of therapeutic efficacy Nature Biotechnology, 2026-05-04. DOI/link Summary: Builds data-rich human lung digital twins from ex vivo lung perfusion, integrating physiology, imaging, transcriptomics, metabolomics and proteomics to forecast organ behavior and therapeutic response. Why it matters: It shows how organ-scale digital twins can be anchored in prospective human-organ measurements rather than purely retrospective clinical modeling. Tags: digital twins; translational biology; precision medicine; computational biology

2. TxPert: using multiple knowledge graphs for prediction of transcriptomic perturbation effects Nature Biotechnology, 2026-05-01. DOI/link Summary: Introduces a deep learning framework that combines basal transcriptomic state encoding with multiple biological knowledge graphs to predict out-of-distribution genetic perturbation responses. Why it matters: Perturbation prediction is central to model-guided experiments and drug discovery, and this paper explicitly benchmarks against strong nonlearned baselines and experimental reproducibility. Tags: AI4Bio; perturbation prediction; transcriptomics; knowledge graphs; machine learning

3. DNA-guided CRISPR-Cas12a effectors for programmable RNA recognition and cleavage Nature Biotechnology, 2026-05-01. DOI/link Summary: Reprograms Cas12a into a DNA-guided, RNA-targeting effector and demonstrates direct RNA detection plus intracellular RNA knockdown. Why it matters: The work expands programmable nucleic-acid engineering beyond canonical RNA-guided CRISPR architectures and creates new design space for RNA diagnostics and manipulation. Tags: CRISPR; RNA; synthetic biology; diagnostics; biotechnology

4. Single-molecule localization and diffusivity microscopy reveals dynamic biomolecular organization in living cells Nature Methods, 2026-04-28. DOI/link Summary: Presents SMLDM, a deep learning-enabled microscopy method that estimates molecule movement and diffusion from single-frame snapshots without trajectory linking. Why it matters: It sharply increases mapping density for live-cell molecular dynamics, helping connect spatial organization with mobility in chromatin, receptors, adhesions and condensates. Tags: bioimage informatics; deep learning; microscopy; single-molecule biophysics

5. Systematically decoding pathological morphologies and molecular profiles with unified multimodal embedding Nature Methods, 2026-04-24. DOI/link Summary: Introduces Multi-Embed, an interpretable multimodal framework for linking pathology morphology with multilayer molecular profiles. Why it matters: Computational pathology is moving from image-only predictors toward morphology-to-molecular reasoning that can support mechanistic disease interpretation. Tags: computational pathology; multimodal learning; molecular profiling; machine learning

6. Direct RNA sequencing and signal alignment reveal RNA structure ensembles in a eukaryotic cell Nature Methods, 2026-04-24. DOI/link Summary: Combines chemical probing, direct RNA sequencing and signal alignment to map RNA structural ensembles at single-molecule resolution in eukaryotic cells. Why it matters: It turns raw direct-sequencing signal into a richer readout of RNA structural heterogeneity, connecting transcript sequence, isoforms and regulatory structure. Tags: RNA structure; direct RNA sequencing; transcriptomics; computational biology

7. High-fidelity intravital imaging of biological dynamics with latent-space-enhanced digital adaptive optics Nature Biotechnology, 2026-04-23. DOI/link Summary: Develops latent-space-enhanced digital adaptive optics for intravital fluorescence microscopy, using wave-optics priors in spatial-angular data to improve aberration estimation.

10. Inducible, split base editors for in vivo cancer functional genomics Nature Biotechnology, 2026-04-15. DOI/link Summary: Designs split, inducible base editors for controlled in vivo cancer functional genomics, reducing constraints from constitutively active deaminase systems. Why it matters: More controllable base-editing screens can improve mutation-level functional genomics in animal models and better separate target effects from editor toxicity.

11. Adaptive optical correction for in vivo two-photon fluorescence microscopy with neural fields Nature Methods, 2026-04-13. DOI/link Summary: Uses neural fields to perform adaptive optical correction for in vivo two-photon microscopy under motion and sample-induced aberration. Why it matters: Neural representations are becoming useful infrastructure for biological imaging, especially when hardware-only correction is difficult or fragile.

Watch list

• Perturbation modeling is maturing: papers now spend more space on realistic out-of-distribution tasks, baselines and reproducibility ceilings.
• RNA-focused foundation models and direct RNA signal analysis are both advancing, suggesting stronger computational tools for RNA function and RNA therapeutics.
• Bioimage informatics is shifting toward latent representations, neural fields and deep-learning-assisted physical correction rather than segmentation alone.
• Experimentally grounded AI4Bio remains the strongest signal: the most useful papers combine model advances with organ systems, live-cell imaging, CRISPR tools or protein engineering validation.
