Chronic care manages long-term, progressive conditions, while acute care handles short-term ones. Here, authors show chronic conditions account for most of the global health burden, with 68% of DALYs and 93% of YLDs attributed to chronic care needs.

Polymer nanofibres can be used to detect mechanical motion. Here, the authors use electrospun piezoelectric nanofibre webs to detect acoustic waves at frequencies below 500 Hz with a good sensitivity at low pressure levels, and study the impact of the fibres morphology and crystalline phase.

As Nature Chemical Biology approaches its third decade we asked a collection of chemical biologists, “What do you think are the most exciting frontiers or the most needed developments in your main field of research?” — here is what they said.

The researchers synthesize organic–inorganic hybrid inverse perovskites that exhibit excellent carrier lifetime and mobility–lifetime product and high resistivity, enabling stable X-ray detectors with performance arguably outperforming state-of-the-art perovskite single-crystal detectors.

Genetic variants at multiple loci of chr5p15.33 have been associated with susceptibility to numerous cancers. Here the authors show that the association of one of these loci may be explained by a variant, rs36115365, influencing telomerase reverse transcriptase (TERT) expression via ZNF148.

The relationship of mycorrhizal associations with latitudinal gradients in tree beta-diversity is unexplored. Using a global dataset approach, this study examines how trees with arbuscular mycorrhizal and ectomycorrhizal associations contribute to latitudinal beta-diversity patterns and the environmental controls of these patterns.

Illuminating internal organs and tissues with high controllability and adaptability remains challenging. Here the authors present a flexible, biodegradable photonic device called iCarP for large area, high intensity, wide spectrum, deeply penetrating, continuous or pulsatile illumination.

Examining drivers of the latitudinal biodiversity gradient in a global database of local tree species richness, the authors show that co-limitation by multiple environmental and anthropogenic factors causes steeper increases in richness with latitude in tropical versus temperate and boreal zones.

Entanglement was observed in top–antitop quark events by the ATLAS experiment produced at the Large Hadron Collider at CERN using a proton–proton collision dataset with a centre-of-mass energy of √s  = 13 TeV and an integrated luminosity of 140 fb⁻¹.

Zhu et al. develop a low-cost donor–acceptor-type hole-selective layer that minimizes interfacial non-radiative charge recombination losses in single-junction and tandem solar cells based on metal halide perovskites with different bandgaps.

Fine-scale geospatial mapping of overweight and wasting (two components of the double burden of malnutrition) in 105 LMICs shows that overweight has increased from 5.2% in 2000 to 6.0% in children under 5 in 2017. Although overall wasting decreased over the same period, most countries are not on track to meet the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025.

Meta-analysis of 36,760 cases and 375,188 controls identifies 54 loci associated with susceptibility to cutaneous melanoma. Further analysis combining nevus count and hair color GWAS results provide insights into the genetic architecture of melanoma.

A cross-sectional study of hospitalized patients with COVID-19 and a longitudinal follow-up study of patients with COVID-19 suggest that SARS-CoV2-specific IgG or IgM seroconversion occurs within 20 days post symptom onset.

Using an in silico network-based discovery approach, the authors identified sildenafil as a repurposable drug for Alzheimer’s disease. Analyzing insurance claims data from over 7 million individuals, they found that sildenafil usage was associated with a reduced risk of Alzheimer’s disease diagnosis.

There are now nearly 1,000 completed bacterial and archaeal genomes available, but as most of them were chosen for sequencing on the basis of their physiology, the data are limited by a highly biased phylogenetic distribution. To explore the value added by choosing microbial genomes for sequencing on the basis of their evolutionary relationships, the genomes of 56 species of Bacteria and Archaea selected to maximize phylogenetic coverage are now sequenced and analysed.

Serotonin is important in depression-like behavior. Here the authors show that dorsal raphe neurons that project to the ventral tegmental area are involved in regulating stress responses in mice.

Developing stable single-atom catalysts (SACs) with a high metal loading remains a challenge due to the difficulty of creating high densities of defects on support materials. Here the authors prepare Pt SACs with high Pt loadings by virtue of strong covalent metal-support interaction, rather than support defects.

Immune responses to pancreatic ductal adenocarcinoma can be inhibited by cancer cells. Here the authors show that high levels of progranulin in PDAC inhibits immune responses by reducing MHC class I antigen presentation through enhanced degradation of MHC class I via autophagy.

The ATLAS Collaboration reports a measurement of the ratio of the decay rates of W bosons to τ leptons and muons, in agreement with universal lepton couplings as postulated in the standard model of particle physics.

The ATLAS experiment at the Large Hadron Collider reports a search for charged-lepton-flavour violation in decays of Z bosons into a τ lepton and an electron or muon of opposite charge.

Surface emission from a topological mid-gap cavity shows large free spectral range and arbitrary mode degeneracy.

Analysis of rare coding variants in the UK Biobank identifies eight genes associated with adult cognitive function, including KDM5B. Rare and common variant signals overlap and contribute additively to the phenotype.

The ATLAS Collaboration reports the observation of the electroweak production of two jets and a Z-boson pair. This process is related to vector-boson scattering and allows the nature of electroweak symmetry breaking to be probed.

Matthew Law, Mark Iles and colleagues report the results of a large-scale genome-wide meta-analysis of cutaneous malignant melanoma. They confirm previously reported association signals and identify five new susceptibility loci, with associated variants mapping within putative melanocyte regulatory elements.

The NLRP3 inflammasome plays an important role in antiviral host responses. Here, the authors reveal that the polymerase of Zika virus binds NLRP3 to facilitate inflammasome complex assembly and induce production of IL-1β in human macrophages, human PBMCs and mice, resulting in pathogenesis in mice.

Following our call to join in the discussion over the suitability of implementing a reporting checklist for bio–nano papers, the community responds.

Quantum electrodynamics predicts a rare process in which light is scattered by light. The ATLAS Collaboration reports signs of this elusive effect in the collisions of ultra-relativistic lead ions.

In this DREAM challenge, 75 methods for the identification of disease-relevant modules from molecular networks are compared and validated with GWAS data. The authors provide practical guidelines for users and establish benchmarks for network analysis.

Ten years after the discovery of the Higgs boson, the ATLAS  experiment at CERN probes its kinematic properties with a significantly larger dataset from 2015–2018 and provides further insights on its interaction with other known particles.

Melanocytic nevus count is associated with melanoma risk. In this study, a meta-analysis of 11 nevus GWAS studies identifies novel SNPs in KITLG and 9q32, and bivariate analysis with melanoma GWAS meta-analysis reveals that most nevus genes affect melanoma risk, while melanoma risk loci do not alter the nevus count.
