To date, experimental induction of hair cell regeneration in mammals leads to immature and poorly differentiated hair cells. Here the authors show that the transcription factor prdm1a plays a crucial role in specifying sensory hair cell types with loss of prdm1a in zebrafish leading to misspecification of hair cells in the sensory lateral line system into ear hair cells.

Single-cell RNA sequencing and spatial transcriptomic approaches reveal major expression changes in outer root cell types when grown in soil versus gel conditions, and also uncover how root tissues communicate and adapt to contrasting soil conditions at single-cell resolution.

The chromatin-remodelling enzyme ATRX and the transcription factor HNF4A are identified as pivotal regulators of colonic epithelial identity, with roles in metastasis in colorectal cancer.

The influence of mRNA splicing on colon cancer development and progression is unclear. In this study, the authors demonstrate that the SRSF1 splicing factor is essential to sustain the stem cell phenotype of WNT-activated colorectal cancers.

Genomic and phenomic screens of 827 wheat landraces from the A. E. Watkins collection provide insight into the wheat population genetic background, unlocking many agronomic traits and revealing haplotypes that could potentially be used to improve modern wheat cultivars.

T cell responses can be generated to either pathogen infection or from priming with a vaccine. Here the authors compare T cell generation, phenotype and single cell transcriptome of participants vaccinated with a mpox vaccine or infected with the virus showing that the virus induced T cells showed more effective function and phenotype.

DNA double strand break repair pathways ensure genome stability and prevent disease. Here the authors show that the actin nucleating factor DIAPH1 and γ-actin promote homologous recombination (HR)-dependent repair. Inherited mutations in DIAPH1 or ACTG1 give rise to clinical deficits similar to those associated with defective HR.

Proteins are often modified by complex carbohydrates (N-glycans). Here, authors identified gene regulators of this process and uncovered links between plasma protein Nglycosylation, metabolic and liver diseases, and anti-inflammatory proteins.

In this work, authors mechanistically explore the impact of the disruption of the Erg11-Ncp1 interaction in Candida albicans. Subsequent cellular stress releases calcium and damages mitochondria, increasing toxic oxidative molecules, and leading fungal cells to self-destruct. These reactions may serve as an approach to enhance antifungal properties of azoles.

A case–control study investigating the causes of recent cases of acute hepatitis of unknown aetiology in 32 children identifies an association between adeno-associated virus infection and host genetics in disease susceptibility.

Baker’s yeast is a workhorse of industrial biotechnology, but it is not suited to overproduce many bulk bioproducts, especially organic acids. Here, the authors identify Pichia occidentalis as an acid tolerant yeast and engineer it for the production of muconic acid using a newly developed genome editing toolkit.

Anaplastic large cell lymphoma is characterized by an NPM–ALK fusion but the cell of origin for this cancer is unclear. Here, the authors show that, in an NPM–ALK mouse model, the tumours likely arise from early thmyocytes and require an initial burst of TCR signalling for initiation.

Viral pathogen load in cancer genomes is estimated through analysis of sequencing data from 2,656 tumors across 35 cancer types using multiple pathogen-detection pipelines, identifying viruses in 382 genomic and 68 transcriptome datasets.

COVID-19 can be associated with neurological complications. Here the authors show that markers of brain injury, but not immune markers, are elevated in the blood of patients with COVID-19 both early and months after SARS-CoV-2 infection, particularly in those with brain dysfunction or neurological diagnoses.

In this phase 1 trial, Hegde et al. treat 13 individuals with advanced sarcoma with lymphodepletion followed by HER2-specific CAR T cells, which were found to be safe and showed antitumor activity.

Dominic Kwiatkowski and colleagues of the MalariaGEN and the WTCCC consortiums report a genome-wide analysis of severe malaria in The Gambia. They provide guidance for design of GWAS in African populations, and demonstrate the usefulness of multipoint imputation based on population-specific sequencing data.

Multi-omics datasets pose major challenges to data interpretation and hypothesis generation owing to their high-dimensional molecular profiles. Here, the authors develop ActivePathways method, which uses data fusion techniques for integrative pathway analysis of multi-omics data and candidate gene discovery.

We evaluate the effects in humans of interleukin-15 co-expression on glypican-3 (GPC3) chimeric antigen receptor (CAR) T cells and demonstrate that IL-15 increases the expansion, intratumoural survival and antitumour activity of GPC3 (expressed in a group of solid cancers) CAR T cells.

Cancers of the same tissue type are characterized with different molecular features depending on anatomical location. Here, the authors show that proximal and distal colon stem cells have distinct transcriptional programs mediated by the transcription factor CDX2, with differential roles in colon cancers based on anatomical location.

Placental dysfunction can affect heart development, but the prevalence of this causality has not been well established. Here, the authors use mouse genetic tools to show that the placenta may constitute a significant source of congenital heart defects.

In this work, the authors study the immunological and virological effects of administering either wild-type anti-HIV-1 broadly neutralizing antibodies (bNAbs) or bNAbs with a mutation that increases binding to Fc-gamma receptors (FcγRs) to rhesus macaques in the acute phase of SHIV_AD8-EO infection.

The electride nature of dense sodium in the transparent hP4 phase, where valence electrons are interstitially localised, lacks experimental confirmation. Here, the authors use single-crystal X-ray diffraction and quantum crystallographic atomic form factors to provide experimental indication of interstitial electron localisation in hP4-Na at 223 GPa, advancing our understanding of high density electrides.

Vyas et al. show that epicardial adipose tissue is a reservoir for a subpopulation of tissue-resident memory T cells that can increase the vulnerability of the heart to atrial fibrillation.

Human pluripotent cells (hPSCs) in standard culture are similar to mouse epiblast cells, but heterogeneity within hPSC cultures complicates comparisons. Here the authors show that a subpopulation of hPSCs enriched for self-renewal capacity have distinct cell cycle, metabolic, DNA methylation, and ATAC-seq profiles.

Two side-by-side papers report that H3K27me3 deposited by polycomb repressive complex 2 represents an epigenetic barrier that restricts naive human pluripotent cell differentiation into alternative lineages including trophoblasts.
