Preprint maps functional impact of 1,456 ARID1B variants linked to neurodevelopmental disorders and cancer

A preprint using structural modelling across more than one million genomes classifies over 600 ARID1B missense variants as damaging to protein interactions or stability, offering a resource for interpreting the large majority of variants that currently lack clinical classification.

Wolbachia-induced cytoplasmic incompatibility produces heritable chromatin modifications in host embryos, preprint reports

A bioRxiv preprint provides evidence that the embryo-lethal effects of Wolbachia-induced cytoplasmic incompatibility are mediated, at least in part, by heritable epigenetic chromatin modifications rather than purely mechanical replication failure.

Preprint maps antiviral RNAi responses across Varroa mite life stages and finds evidence of vertical virus transmission

A bioRxiv preprint characterises how the honey bee parasite Varroa destructor deploys RNA interference against viruses across its life cycle, revealing that established viral infections produce an unusual small RNA signature and that viruses are transmitted vertically through mite generations.

Synthetic fusion promoters improve balanced transgene expression in rods and cones in retinal gene therapy preprint

A bioRxiv preprint describes two engineered fusion promoters — Pikali and Nocchu — that drive broader and more balanced transgene expression across both rod and cone photoreceptors than existing options, a longstanding challenge in retinal gene therapy research.

MAGI preprint proposes mechanistic variant annotation pipeline built on genomic transformer models

Researchers have posted a preprint describing MAGI, a computational method that uses genomic foundation models to generate mechanistic annotations of genetic variants — aiming to move beyond binary pathogenicity labels towards interpretable biological explanations.

Natural genetic variation in Drosophila spans full range of predicted photoreceptor rhodopsin expression phenotypes

A bioRxiv preprint using wild and wild-derived Drosophila lines finds that standing genetic variation is sufficient to produce virtually every predicted qualitative change in Rh5/Rh6 expression in R8 photoreceptors, illustrating the breadth of phenotypic potential in natural populations.

Preprint identifies achiasmatic meiosis as mechanism enabling clonal genome propagation in hybrid crucian carp females

Researchers studying the hexaploid crucian carp Carassius gibelio report that asexual females use meiosis without chromosomal crossover — achiasmatic meiosis — to produce unreduced eggs carrying both the clonal genome and supernumerary B chromosomes.

PLOS Genetics study demonstrates intramolecular epistasis drives clustering of adaptive substitutions in Drosophila Trio protein

Researchers at Columbia University have used population genetic and functional approaches to show that spatially clustered amino acid substitutions in the Drosophila Trio protein arise through intramolecular epistasis, providing rare direct evidence for a theoretically predicted but empirically understudied evolutionary constraint.

Preprint: gut gap-junction gene inx-20 extends reproductive lifespan in C. elegans without major effect on overall longevity

A bioRxiv preprint reports that loss of the innexin gene inx-20 in the alimentary tract of the roundworm C. elegans substantially prolongs reproductive span independently of somatic ageing, suggesting gut-to-germline signalling shapes the timing of reproductive senescence.

Single-cell multi-omic atlas of human dendritic cell differentiation links inherited disease risk to specific immune cell subsets

A bioRxiv preprint presents a chromatin accessibility and transcriptomic atlas of human dendritic cell development from haematopoietic stem cells, integrating GWAS data from immune-mediated diseases to pinpoint which DC subsets mediate inherited genetic risk.

Computational model proposes ploidy buffers developmental gene expression noise to explain hybrid vigour

A bioRxiv preprint uses abstract multicellular development modelling to argue that increased ploidy — in both diploid hybrids and polyploids — reduces the impact of gene expression noise on cell fate determination, offering a mechanistic basis for heterosis.

High-throughput single-cell eQTL mapping in yeast reveals how genetic variants shape rapid transcriptional responses to stress

A bioRxiv preprint uses a scalable 'one-pot' single-cell RNA-seq approach to map expression quantitative trait loci in yeast during acute salt stress and nutrient repletion, extending eQTL analysis from steady-state transcript levels into dynamic physiological transitions.

Preprint: undergraduate CURE screen identifies Bacillus isolates that suppress Ras/MAPK signalling in C. elegans

The WormFood CURE, a course-based undergraduate research programme, used a C. elegans multivulva phenotype assay to screen environmental bacteria for bioactive metabolites and found two Bacillus strains capable of suppressing ectopic Ras pathway activation.

Preprint reports novel MGME1 variant causing mitochondrial DNA depletion syndrome in South Indian families

A bioRxiv preprint describes a homozygous missense variant in MGME1 — a nuclear-encoded gene essential for mitochondrial DNA maintenance — identified in five affected individuals from unrelated South Indian families presenting with multi-systemic mitochondrial disease.

Preprint proposes unified framework for Hardy-Weinberg equilibrium testing on the X chromosome

A bioRxiv preprint develops a general statistical approach to Hardy-Weinberg equilibrium inference at X-linked loci, addressing longstanding ambiguities that arise from sex-specific genotype structures and differing assumptions about allele frequency differences between sexes.

Preprint redefines role of RNA polymerase ω subunit in transcription-replication conflicts

A bioRxiv preprint from Cold Spring Harbor Laboratory suggests the ω subunit of bacterial RNA polymerase regulates transcriptional processivity and helps resolve collisions with the replication machinery, challenging its traditional characterisation as a mere assembly chaperone.
