Genome-wide analyses identify 30 independent loci associated with obsessive–compulsive disorder, highlighting genetic overlap with other psychiatric disorders and implicating putative effector genes and cell types contributing to its etiology.

PCSK9 interacts with LDL receptor, causing its degradation, and consequently reduces the clearance of LDL. Here, Gustafsen et al. show that PCSK9 interacts with heparan sulfate proteoglycans and this binding favors LDLR degradation. Pharmacological inhibition of this binding can be exploited as therapeutic intervention to lower LDL levels.

A new mass spectrometry strategy combines the advantages of data-dependent and data-independent acquisition.

Studies on protein–protein interactions using proteins containing d- or l-amino acids show that stereoselectivity of binding varies with the degree of disorder within the complex.

The expression of oncogenic MYC paralogs in small cell lung cancer is mutually exclusive. In this study, the authors show that MYC, but not MYCN or MYCL, represses BCL2, resulting in cells that are uniquely sensitive to apoptosis, and find that CHK1 and AURKA inhibitors may be useful for treating these cancers.

An initial draft of the human pangenome is presented and made publicly available by the Human Pangenome Reference Consortium; the draft contains 94 de novo haplotype assemblies from 47 ancestrally diverse individuals.

The intrinsic efficiency of electrocaloric materials has been largely overlooked. Here, the authors use the parameter materials efficiency as the figure of merit to rank caloric materials, reporting on the materials efficiency of highly ordered bulk lead scandium tantalate PST.

In bacteria Zn2+-dependent deacylases are underexplored. Here, the authors identify bacterial deacylases, providing systemic structure-function analyses to reveal the basis of substrate specificity, acyl-chain preference and inhibition.

Mineralized plaque, or dental calculus, is a valuable reservoir of the ancient oral microbiome. Here, the authors use quantitative metaproteomics to analyze the dental calculus of 21 individuals from a medieval cemetery, identifying human and microbial proteins that shed light on their oral health status.

The evolutionary history of pigs in Africa is unclear. Here, the authors examine 67 whole genomes, finding incomplete speciation between bushpigs and red river hogs as well as evidence suggesting that humans brought bushpigs to Madagascar 1000-5000 years ago.

An analysis involving the shotgun sequencing of more than 300 ancient genomes from Eurasia reveals a deep east–west genetic divide from the Black Sea to the Baltic, and provides insight into the distinct effects of the Neolithic transition on either side of this boundary.

Ruth Loos and colleagues report a meta-analysis of genome-wide association studies in 181,171 individuals identifying 14 new loci associated with heart rate and test these for association with cardiac conduction, rhythm disorders and cardiovascular disease. Their experimental studies in Drosophila melanogaster and zebrafish models provide support for a role for 20 candidate genes at 11 of these loci in regulation of heart rate.

Christina Warinner and colleagues report a high-resolution characterization of the oral microbiome isolated from the dental tissues of adult skeletons dating to 1100 CE and showing evidence of periodontal disease. They show the long-term carriage of a diverse range of opportunistic pathogens in the oral cavity and reconstruct the genome of the periodontal pathogen Tannerella forsythia.

Localizing phosphorylation sites by data-independent acquisition (DIA)-based proteomics is still challenging. Here, the authors develop algorithms for phosphosite localization and stoichiometry determination, and incorporate them into single-shot DIA-phosphoproteomics workflows.

Hundreds of genetic loci associated with age at menopause, combined with experimental evidence in mice, highlight mechanisms of reproductive ageing across the lifespan.

Donor-acceptor molecules are important components for molecular electronics applications. Here, the authors show that donor-acceptor molecular wires exhibit changes in conductivity under the influence of small changes in the environment.

Neuropeptide research is challenged by technical difficulties in identifying new bioactive peptides. Here the authors present an analytical pipeline for large-scale peptidomics applied to the rat hypothalamus, identifying thousands of endogenous neuropeptides and their post-translational modifications.

Stratified medicine promises to tailor treatment for individual patients, however it remains a major challenge to leverage genetic risk data to aid patient stratification. Here the authors introduce an approach to stratify individuals based on the aggregated impact of their genetic risk factor profiles on tissue-specific gene expression levels, and highlight its ability to identify biologically meaningful and clinically actionable patient subgroups, supporting the notion of different patient ‘biotypes’ characterized by partially distinct disease mechanisms.

Managing forests for the supply of multiple ecosystem services (ES) is key given potential trade-offs among services. Here, the authors analyse how forest stand attributes generate trade-offs among ES and the relative contribution of forest attributes and environmental factors to predict services.

Comparisons within the human pangenome establish that homologous regions on short arms of heterologous human acrocentric chromosomes actively recombine, leading to the high rate of Robertsonian translocation breakpoints in these regions.

Integration of GWAS and single-cell transcriptomic data from the entire nervous system systematically identifies cell types underlying brain complex traits and provides insights into the etiology of Parkinson’s disease.

Weight regain after weight loss is a challenge in obesity treatment and may involve altered eating and sedentary behaviour after weight loss. Here the authors report an exploratory analysis of eating- and physical activity-related outcomes from a randomized controlled trial for weight loss maintenance with exercise and liraglutide single or combination treatment.

Christopher Newton-Cheh and colleagues report genome-wide association analyses for QT interval, an electrocardiographic measure reflecting myocardial repolarization, in 100,000 individuals.

The potential use of circulating tumour DNA in classic Hodgkin lymphoma detection, classification and monitoring is defined.

Current histone microarrays cannot be used to directly study the transient interactions of histone deacetylases (HDACs). Here, the authors show that hydroxamic acid-modified microarrays can capture HDACs, provide insights into their substrate specificity, and serve to develop peptide inhibitors.

Relatives of patients with amyotrophic lateral sclerosis have an unexpectedly high incidence of schizophrenia. Here, the authors show a genetic link between the two conditions, suggesting shared neurobiological mechanisms.

Bacteria communicate through excretion of minute amounts of chemical signalling molecules that affect virulence, biofilm formation and colonization. In staphylococci, these molecules, called autoinducing peptides, are macrocyclic thiolactone-containing peptides. Now, a simple enrichment method, based on chemoselective capture on polymer beads, has been developed that enables the identification of previously unknown autoinducing peptides.
