Long-read RNA-seq delineates temporal transcriptional dynamics in multiplexed and sexed single medfly embryos

This study utilizes long-read RNA sequencing combined with absolute quantification and sex-specific analysis to map high-resolution temporal transcriptional dynamics in single Mediterranean fruit fly embryos, revealing novel genes, developmental heterogeneity, zygotic genome activation waves, and early dosage compensation mechanisms.

Gut microbial arginine biosynthesis mediates the anti-obesity effect of a pasteurized Akkermansia muciniphila 11

This study demonstrates that pasteurized *Akkermansia muciniphila* alleviates obesity not by colonizing the gut, but by reshaping the microbiota to enrich *Faecalibaculum rodentium*, thereby boosting microbial arginine synthesis which activates the host NO–AMPK signaling axis to rebalance lipid metabolism.

From shared genes to staged decay: ecosystem-specific genomic potential for litter decomposition in soils

By integrating global soil metagenomes with standardized tea-bag decomposition assays, this study reveals that ecosystem-specific litter decay rates are driven not by the presence of unique genes, but by the stage-specific abundance and variation of shared carbohydrate-active enzymes, offering a refined genomic framework for carbon-cycle modeling within defined environmental limits.

Chromosome-scale genome of a twig-girdler longhorn beetle reveals clustered genomic organization of herbivory-linked functions

This study presents a chromosome-scale genome and transcriptome of the twig-girdler beetle *Oncideres impluviata*, revealing that clustered genomic architectures, including tandem gene arrays and multi-family superloci, facilitate the coordinated expression of chemosensory, detoxification, and digestive functions essential for host adaptation and complex plant-manipulation behaviors.
