Chronic tinnitus is often treated with cognitive-behavioural therapy, hearing aids, counselling, or sound therapy, but their combined benefit is unclear. Here, the authors show, in a multicentre randomised trial, that combination treatments improve tinnitus scores more than single therapies, though benefits appear compensatory rather than synergistic.

Mapping the operational chemical, physical and electronic structure of an oxygen evolution electrocatalyst at the nanoscale links the properties of the material with the observed oxygen evolution activity.

A global network of researchers was formed to investigate the role of human genetics in SARS-CoV-2 infection and COVID-19 severity; this paper reports 13 genome-wide significant loci and potentially actionable mechanisms in response to infection.

Membrane-free complex coacervate microdroplets are compelling models for primitive compartmentalization, but it is unclear how molecular co-operativity influences physicochemical properties and activity of membrane-free compartments. Here, the authors use RNA/peptide coacervates as a model to reveal the relationship between coacervate properties and ribozyme activity.

A large-scale mouse study reveals that while existing epigenomic data detect many developmental enhancers, a substantial fraction is missed - highlighting the need for expanded resources to fully annotate enhancers genome-wide.

An analysis of 24,202 critical cases of COVID-19 identifies potentially druggable targets in inflammatory signalling (JAK1), monocyte–macrophage activation and endothelial permeability (PDE4A), immunometabolism (SLC2A5 and AK5), and host factors required for viral entry and replication (TMPRSS2 and RAB2A).

A genome-wide association study meta-analysis combined with multiomics data of osteoarthritis identifies 700 effector genes as well as biological processes with a convergent involvement of multiple effector genes; 10% of these genes express the target of approved drugs.

Alterations in the tumour suppressor genes STK11 and/or KEAP1 can identify patients with advanced non-small-cell lung cancer who are likely to benefit from combinations of PD-(L)1 and CTLA4 immune checkpoint inhibitors added to chemotherapy.

This study presents the first annual update of the indicator framework developed by the Food Systems Countdown Initiative, published in Nature Food in 2023. Almost half of all indicators show some desirable trends. Governance and resilience indicators were revealed as the most connected across themes, constituting entry points for transformative change.

Multi-ancestry genome-wide analyses identify new risk loci for age-related macular degeneration. Ancestry-specific analyses identify distinct effects at major risk loci, including smaller effect sizes for CFH risk alleles in haplotypes of African ancestry.

Cancer genetics has benefited from the advent of next generation sequencing, yet a comparison of sequencing and analysis techniques is lacking. Here, the authors sequence a normal-tumour pair and perform data analysis at multiple institutes and highlight some of the pitfalls associated with the different methods.

Aldolases have been a mainstay in synthesis, but their scope has been limited to activated electrophiles. Now carbon–carbon bond formation with ketone electrophiles is enabled by transaldolases, which form a strong nucleophile that is resistant to protonation. This chemistry enables convergent synthesis of non-canonical amino acids bearing tertiary alcohol side chains.

Single-nucleus and spatial, whole-transcriptome profiling of 43 pancreatic adenocarcinomas provides a refined molecular and cellular classification, highlighting a new neoadjuvant treatment-associated neural-like progenitor tumor cell state.

A survey of SARS-CoV-2 RBD antibodies identifies those with activity against diverse SARS-CoV-2 variants and SARS-related coronaviruses, highlighting epitopes and features to prioritize in antibody and vaccine development.

A genome-wide association study including over 76,000 individuals with schizophrenia and over 243,000 control individuals identifies common variant associations at 287 genomic loci, and further fine-mapping analyses highlight the importance of genes involved in synaptic processes.

This overview of the ENCODE project outlines the data accumulated so far, revealing that 80% of the human genome now has at least one biochemical function assigned to it; the newly identified functional elements should aid the interpretation of results of genome-wide association studies, as many correspond to sites of association with human disease.

GEMIN5, an RNA-binding protein, is required for formation of small nuclear ribonucleoproteins. Here, the authors identify loss of function mutations in GEMIN5 that are associated with a human neurodevelopmental disorder.

De novo assemblies of 43 Y chromosomes spanning 182,900 years of human evolution reveal considerable diversity in the size and structure of the human Y chromosome.

Evidence synthesized from 252 large-herbivore exclusion studies suggests that herbivore-induced change in dominance, independent of site productivity or precipitation, best predicts herbivore effects on biodiversity in grassland and savannah sites.

Which combination of current genome sequencing and assembly approaches results in high-quality, complete diploid genome assemblies is determined.

Hydroxyglutarate synthase (HglS) converts 2-oxoadipate to D-2- hydroxyglutarate during lysine catabolism in bacteria. Here the authors use structural and biochemical approaches to show that HglS acts via successive decarboxylation and intramolecular hydroxylation and that homologous enzymes catalyze the final step of lysine catabolism in plants.
