A High-Quality Genome Assembly of Chaetoceros muelleri Reveals Extensive Gene Duplication, Functional Diversification, and Unique Lineage-Specific Innovation

This study presents the first high-quality nuclear genome assembly of *Chaetoceros muelleri*, derived from resurrected Baltic Sea sediments, which reveals extensive gene duplication, transposable element-driven plasticity, and lineage-specific innovations that underpin the diatom's evolutionary adaptability and ecological success.

Protein without farms: What comparative genomics reveals about ''Power-to-Food'' microbes

This study utilizes comparative genomics to characterize the distinct genomic architectures, metabolic capabilities, and safety profiles of two hydrogen-oxidizing bacteria, *Cupriavidus necator* H16 and *Xanthobacter* sp. SoF1, thereby establishing a scientific foundation for selecting and engineering robust, food-grade microbes for scalable, land-independent protein production on Earth and in space.

Methylation Clocks Do Not Predict Age or Alzheimer's Disease Risk Across Genetically Admixed Individuals

This study demonstrates that current DNA methylation clocks lack portability and accuracy in predicting age and Alzheimer's disease risk across genetically admixed populations, particularly those with African ancestry, due to widespread differences in methylation patterns and higher frequencies of methylation-associated genetic variants (meQTLs) in these groups.

Brain cell type nuclei enrichment without fixative for nanoCUT&Tag and other omics approaches

This paper presents a novel workflow for isolating unfixed nuclei from frozen human and mouse brain tissue, enriching specific cell types via fluorescence-activated nuclei sorting (FANS) based on DNA-bound proteins, and performing low-input epigenomic profiling using nanoCUT&Tag to enable cell-type-specific analysis of the neurovascular unit in both healthy and neurodegenerative contexts.

DenMark: A Bayesian Hierarchical Model for Identifying Cell-Density Correlated Genes from Spatial Transcriptomics

DenMark is a novel Bayesian hierarchical model that leverages Hilbert space Gaussian process approximations to jointly model cell locations and gene expression in single-cell-resolution spatial transcriptomics, enabling the robust identification and uncertainty quantification of genes whose expression correlates with local cell density across diverse tissues and platforms.

Hybrid crosses reveal a cell-type-specific landscape of mouse regulatory variation

This study presents a comprehensive single-nucleus RNA-seq atlas of 6.7 million nuclei from mouse F1 hybrids across eight tissue groups, revealing that while cis-acting regulatory variation drives divergence, trans-acting effects are highly cell-type-specific and often masked in bulk tissue analyses, thereby establishing a foundational framework for understanding the complex interplay between genetic variation and cell-type-specific gene regulation.

Comparative Genomics Reveals the Ancestral Recombination Landscape of Placental Mammals

By reconstructing an ancestral placental mammal karyotype and recombination map, this study reveals that while autosomal recombination landscapes are not conserved across species like the X chromosome, ancestral regions with low recombination rates are under stronger purifying selection and enriched for cellular functions, whereas high-recombination regions are less constrained and associated with regulatory and immune systems.

LoRTIA Plus: a chemistry-agnostic, feature-first software package for long-read transcriptome annotation

LoRTIA Plus is a chemistry-agnostic software suite that outperforms existing tools in annotating and reconstructing long-read transcriptomes across diverse genomes and library chemistries by employing adapter-aware filtering and quality-based criteria to achieve superior recall and precision for transcription start sites, end sites, and novel isoforms.

WGT-aware analysis reveals increased complexity in the yohimbane biosynthesis pathway of Rauvolfia tetraphylla

This paper reanalyzes the *Rauvolfia tetraphylla* yohimbane biosynthesis pathway by demonstrating that previous findings were compromised by a lack of haplotype phasing and whole-genome triplication awareness, leading to the identification of chimeric genes and revealing a more complex, homeolog-specific enzymatic organization than previously reported.

Developmental Correlates of Epigenetic and Polygenic Indices of Cognition and Educational Attainment from Birth to Young Adulthood

This study demonstrates that an epigenetic index of adult cognition ("Epigenetic-g") captures distinct genetic and environmental variation in children's cognitive and academic performance that is not reflected by polygenic indices, showing plasticity in early childhood and moderate stability by adolescence without predicting longitudinal cognitive growth.

Global population structure and phase variation of serotype 12F Streptococcus pneumoniae following the introduction of pneumococcal conjugate vaccine

This study reveals that the global rise of pneumococcal serotype 12F following vaccine introduction is driven by both distinct regional lineages and a multidrug-resistant global clone, while also identifying reversible strand-slippage mutations in the *wciJ* gene as a novel mechanism for phase variation that allows subpopulations to evade vaccine-induced antibody killing.
