Multi-ancestry genome-wide association analyses identify new risk loci for Parkinson’s disease, and fine-mapping and co-localization analyses implicate candidate genes whose expression is associated with disease susceptibility.

Severe sepsis has a high mortality rate. Here, the authors provide genomic, transcriptomic, proteomic and metabolomic data across four sepsis-causing pathogens and identify a signature of global increase in fatty acid and lipid biosynthesis as well as cholesterol acquisition.

Quasi-2D halide perovskites are attracting increasing attention for light-emitting devices. Here, the authors demonstrated efficient and stable quasi-2D perovskite LEDs enabled by suppressed phase disproportionation with newly designed organic ligands.

Expansion microscopy (ExM) is advancing, but lacks consensus on validation structures. Microtubules are an ideal ExM validation tool, due to their size, which is optimal for high-resolution techniques, and to their specific labeling protocols.

A genomic constraint map for the human genome constructed using data from 76,156 human genomes from the Genome Aggregation Database shows that non-coding constrained regions are enriched for regulatory elements and variants associated with complex diseases and traits.

Patricia Munroe, Joanna Howson and colleagues genotype ∼350,000 individuals and identify 30 new blood pressure– or hypertension-associated risk loci. Their analyses provide insights into the pathophysiology of hypertension and highlight new potential targets for clinical intervention.

Mark Caulfield, Paul Elliott and colleagues use data from the UK Biobank to perform genome-wide association analysis for blood pressure traits. They identify and validate 107 novel loci and highlight new biological pathways for potential therapeutic intervention for hypertension.

Jumonji-C ___domain containing protein 5 (JMJD5) is essential for animal development but its catalytic activity has remained elusive so far. Here the authors show that human JMJD5 is an arginyl-hydroxylase and present the cofactor, substrate and product bound JMJD5 crystal structures.

JmjC histone demethylases (KDMs) are cancer targets due to their links to cell proliferation, but selective inhibition remains a challenge. Here the authors identify potent inhibitors of KDM4A-C—viain vitroselection from a vast library of cyclic peptides—that show selectivity over other KDMs.

Exome-wide analysis identifies rare and low-frequency coding variants associated with body mass index. Gene-based meta-analysis and functional studies implicate 13 genes, eight of which are novel, and neuronal pathways as factors in human obesity.

The spatial and physical nature of tumour growth remains unclear. Combining whole-tumour images from clear cell renal cell carcinoma with genomic data, the authors show more aggressive subclonal growth and metastasizing subclones in the tumour centre.

A meta-analysis of soil incubation studies from the permafrost zone suggests that thawing under aerobic conditions, which releases CO₂, will strengthen the permafrost carbon feedback more than waterlogged systems, which releases CO₂ and CH₄.

A combined modelling and tumour analysis approach is used to study the temporal and spatial patterns of subclone evolution in the TRACERx renal study. Studying the tumour shape and spatial features of clonal diversity in early-stage tumours may allow the prediction of tumour progression and patterns of subclone diversification over time.

Here, the authors perform ATAC-seq on four distinct cell populations from three different regions of the human brain, finding that chromatin accessibility varies greatly by cell type and less by brain region. This study reveals differences in biological function and gene regulation, as well as overlap of genetic variants associated with schizophrenia and other neuropsychiatric traits.

Here the authors demonstrate the active control of an all-optical switch harnessing the interaction of light with the constituent materials. The response speeds up by two orders of magnitude and scales accordingly with the strength of the light matter interaction.

Alzheimer’s disease has been associated with increased structural brain aging. Here the authors describe a model that predicts brain aging from resting state functional connectivity data, and demonstrate this is accelerated in individuals with pre-clinical familial Alzheimer’s disease.

This study finds that sST2 is a disease-causing factor for Alzheimer’s disease. Higher sST2 levels impair microglial Aβ clearance in APOE4⁺ female individuals. A genetic variant, rs1921622, is associated with a reduction in sST2 level and protects against AD in APOE4⁺ female individuals.

In Alzheimer’s disease (AD) tau and neurodegeneration have complex regional relationships. Here, the authors show neuronal hypometabolism discordant with tau burden defines functional resilience or susceptibility to Alzheimer’s pathology via limbic/cortical axes. Susceptible groups have faster cognitive decline and evidence of non-Alzheimer’s pathologies.
