Analysis of whole-genome sequences of 25,465 individuals of European ancestry shows that rare variants contribute substantially to the heritability of height and body mass index.

Impressive progress has been achieved in isolating quantum systems from the environment and coherently controlling their dynamics. However, engineering the dynamics of many particles by a controlled coupling to an environment (in an 'open' quantum system) remains largely unexplored. Here, an approach is demonstrated based on ion-trap technology for simulating an open quantum system with up to five qubits. By adding controlled dissipation to coherent operations, the work offers novel prospects for open-system quantum simulation and computation.

Ventral tegmental area (VTA) is involved in reward behaviours, but the precise contribution of VTA glutamatergic neurons to this process is not known. Here the authors show that phasic but not sustained optogenetic stimulation of VTA glutamatergic neurons is rewarding and involves co-release of GABA.

Three-dimensional imaging of the fetal heart and quantification of blood flow in the surrounding vessels is very challenging because the heart is small and the fetus is free to move in the womb. Here, the authors demonstrate motion-corrected 4D flow MRI of the whole fetal heart and major vessels.

Roger Milne and colleagues conduct a genome-wide association study for estrogen receptor (ER)-negative breast cancer combined with BRCA1 mutation carriers in a large cohort. They identify ten new risk variants and find high genetic correlation between breast cancer risk for BRCA1 mutation carriers and risk of ER-negative breast cancer in the general population.

Missense variants in RNA-binding proteins underlie many diseases. Here the authors report an oculopharyngeal muscular dystrophy caused by heterozygous frameshift mutations in HNRNPA2B1 that alter its nucleocytoplasmic transport dynamics and result in cytoplasmic accumulation of hnRNPA2 protein.

Topological kink modes are peculiar edge excitations that take place at domain boundaries of magnetic fields inside homogeneous materials. Here, the authors experimentally observe kink magnetoplasmons in a 2D electron gas using custom-shaped strong permanent magnets on top of a GaAs/AlGaAs heterojunction.

The progress in pre-clinical drug discovery for Wilms tumor (WT) is limited by a lack of disease models. Here, the authors develop 45 heterotopic WT patient-derived xenografts including several anaplastic models that recapitulate the biological heterogeneity of WT, and propose this as a resource for evaluating future therapeutics for WT.

Two doses of the coronavirus disease 2019 vaccine ChAdOx1 nCoV-19 boost antibody responses and functions in phase 1/2 trial participants.

Unlike Amazonian forests, African forests have maintained their carbon sink until recently but by 2030 the African carbon sink will have shrunk by 14 per cent and the Amazonian sink will reach almost zero.

Transcriptomic and histological profiling of gut biopsies from multiple independent cohorts of patients with inflammatory bowel disease identifies distinct histopathological, molecular and cellular features associated with treatment response, providing insights for patient stratification and precision therapy.

Bacterial communities are vital for ecosystem services, but their dynamics and functioning are challenging to predict. This study shows that community dynamics are reproducible, but small initial compositional differences can lead to divergent functional outcomes, highlighting key constraints on predictability.

An analysis of metagenomic sequencing of stool samples from multiple cohorts of patients with melanoma treated with immune checkpoint blockade uncovers microbiome correlates of response to therapy and also reveals widespread variability across populations.

An analysis of 52 million births in 26 countries shows small reductions in preterm birth during the first to third months of lockdown. Further research is needed to examine causal pathways.

Cytoplasmic, amyloid-like oligomeric assemblies that contain TDP-43 are increased in damaged tissues with elevated regeneration, thereby enhancing the possibility of amyloid fibre formation and/or aggregation of TDP-43 in disease.

Most people who are infected with SARS-CoV-2 seroconvert within a few weeks, but the determinants and duration of the antibody response are not known. Here, the authors characterise these features of the immune response using data from a large representative community sample of the UK population.

Spitzoid neoplasms constitute a spectrum of melanocytic tumours, characterized by distinct clinical, pathological and genetic features. Here, Wiesner et al. show that kinase fusions represent the majority of oncogenic aberrations in spitzoid neoplasms and may serve as therapeutic targets for metastatic spitzoid melanoma.

The authors analyse tree responses to an extreme heat and drought event across South America to understand long-term climate resistance. While no more sensitive to this than previous lesser events, forests in drier climates showed the greatest impacts and thus vulnerability to climate extremes.

Antimicrobial peptide LL37 can bind nucleic acids and potentiate their sensing by endosomal TLRs. Here the authors show that LL37 binds to RNA from neutrophil extracellular traps (NETs), which amplifies inflammation and production of more LL37 and NETs via TLR8/13, suggesting that LL37 contribution to psoriasis may be fueled by NET-associated RNA.
