BARCODE: A Chromosome Karyotype Analysis Model Based on a Banding Code Framework

BARCODE is an interpretable, data-efficient image-to-sequence model that converts chromosome G-banding patterns into ISCN-aligned symbolic sequences to enable zero-shot structural abnormality detection and precise band-level localization without requiring training on abnormal samples.

Longitudinal multi-omic profiling of a pig-to-human lung xenograft reveals phased immune and tissue-remodeling responses

This study utilizes longitudinal multi-omic profiling to characterize the phased immune and tissue-remodeling responses of a six-gene-edited pig-to-human lung xenograft over nine days, revealing distinct molecular signatures of complement activation, myeloid remodeling, and epithelial recovery that inform future donor engineering and immunosuppressive strategies.

Chromatin regulator perturbation causes heme pathway imbalance in yeast and human cells

This study reveals that perturbing specific chromatin regulators disrupts the transcriptional balance of the heme biosynthesis pathway—particularly affecting its middle enzymes while sparing the iron-regulated terminal enzyme—leading to toxic porphyrin accumulation in yeast and contributing to heme imbalance in human cancers.

Athletes exhibit distinct gut microbial signatures and predicted metabolic functions compared with sedentary adults

This study demonstrates that long-term exercise training in Asian competitive athletes is associated with a healthier gut microbiome characterized by higher diversity, beneficial taxonomic enrichment, and enhanced metabolic functions, which can be accurately distinguished from sedentary individuals using machine learning models to identify potential biomarkers for exercise adaptation.

A structurally and evolutionarily validated catalog of taxonomically restricted and de novo genes in the Anopheles gambiae species complex

This study presents a rigorously validated catalog of taxonomically restricted and de novo genes in the *Anopheles gambiae* species complex by overcoming assembly artifacts and homology-detection failures through a cross-species core-family framework, revealing that these lineage-specific innovations are transcribed, constrained, and exhibit a structural disorder gradient consistent with de novo gene birth models.

Single-cell analysis of pre-rRNA in Escherichia coli indicates distinct pathways of action for YbeX and YbeY proteins in ribosome biogenesis

Single-cell analysis reveals that while both YbeX and YbeY are involved in ribosome biogenesis, YbeX deletion under magnesium limitation causes heterogeneous accumulation of 17S pre-rRNA across individual cells leading to a lag phase, whereas YbeY deletion results in more uniform pre-rRNA accumulation during exponential growth, indicating distinct mechanisms of action for these proteins.
