FEMA-Long: Modeling unstructured covariances for discovery of time-dependent effects in large-scale longitudinal datasets

The paper introduces FEMA-Long, a computationally scalable framework that extends linear mixed-effects modeling to flexibly capture unstructured, time-dependent covariances and non-linear covariate effects in high-dimensional longitudinal data, enabling the discovery of dynamic genetic patterns as demonstrated in a large-scale genome-wide association study of infant growth.

Evolutionary and functional genomics reveal that Ralstonia wilt pathogens actively deploy antimicrobial warfare while leveraging physiological adaptations during plant infection

By integrating high-throughput RB-TnSeq fitness screens in tomato plants with comparative evolutionary genomics, this study reveals that *Ralstonia solanacearum* pathogens rely on both conserved physiological adaptations and strain-specific antimicrobial warfare mechanisms, including Type VI secretion systems, to thrive within the plant vascular niche.

Two ancient nuclear lineages and divergent reproductive strategies drive global success of the wheat stripe rust pathogen

Population-genomic analysis of 507 global isolates reveals that the wheat stripe rust pathogen's global success is driven by two ancient nuclear lineages that diverged before modern agriculture, forming distinct homozygous and globally dominant heterokaryotic hybrid populations that utilize both clonal expansion with somatic nuclear exchange and sexual recombination to achieve convergent evolutionary adaptation.

Reconstructing their genomes confirms the historically attested genealogy of the two medieval emperors Otto I (the Great) and Heinrich II (Saint Henry)

Ancient whole-genome sequencing of the purported remains of medieval emperors Otto I and Heinrich II confirms their historically attested great-uncle/grandnephew relationship, thereby authenticating the remains and establishing them as valuable ground-truth resources for refining bio-archaeological dating methods and tracing elite European lineages.

A meta-analysis of chromatin-associated loci provides insights into mechanistic interpretations of trait heritability

This meta-analysis of chromatin accessibility QTLs (caQTLs) across diverse tissues demonstrates that they are more effective than expression QTLs (eQTLs) at identifying regulatory variants at functionally important genes, thereby offering a more sensitive mechanism for interpreting the heritability of complex traits discovered through genome-wide association studies.

Body size, dental pathology and maternal genetic diversity of ancient horses in the eastern Baltic Sea region and western Russia

This study investigates the body size, dental pathology, and maternal genetic diversity of ancient horses in the eastern Baltic and western Russia, revealing that wild populations were pony-sized, the earliest domestic horses in Lithuania date to 799–570 cal BCE with confirmed bit wear, and high mitochondrial DNA diversity indicates multiple maternal lineages.

Holistic meta-analysis of Caenorhabditis elegans germ granule proteomics reveals complex dynamics and new candidate granule associated proteins

This paper presents a holistic meta-analysis of *C. elegans* germ granule proteomics data, revealing low reproducibility in individual interaction screens due to the dynamic nature of these condensates and introducing a novel algorithmic approach to robustly identify granule-associated proteins and map their complex organizational dynamics.

Linking Codon- and Protein-Level Mutation Scores to Population Genetics Reveals Heterogeneous Selection Efficiency Across Escherichia coli Lineages

By analyzing 81,440 *Escherichia coli* genomes using Direct Coupling Analysis, this study reveals that selection efficiency varies dramatically across lineages—dropping 10,000-fold in pathogenic populations compared to the species as a whole—and demonstrates how population genetics data can validate protein-level mutation scores while highlighting the vast difference in selection intensity between synonymous and non-synonymous mutations.

Molecular characterization of the heterozygous loss of function mutations in the X-linked PCDH19 gene causing PCDH19-Cluster Epilepsy

This study utilizes CRISPR/Cas9-generated mouse and human embryonic stem cell models to demonstrate that heterozygous PCDH19 mutations cause PCDH19-Cluster Epilepsy through specific gene expression defects in developmental and neuronal pathways, while revealing that neurite morphology correlates directly with the levels of wild-type PCDH19 protein.
