Exposome analyses across 34 countries showed that social exposures were associated with faster functional brain aging and physical exposures with faster structural brain aging.

The CMS experiment at CERN reports one of the highest-precision measurements of the W boson mass, finding it in line with standard model predictions and at odds with recent anomalous measurements.

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.

The advantage of living in cities compared with rural areas with respect to height and BMI in children and adolescents has generally become smaller globally from 1990 to 2020, except in sub-Saharan Africa.

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).

The CMS Collaboration reports the measurement of the spin, parity, and charge conjugation properties of all-charm tetraquarks, exotic fleeting particles formed in proton–proton collisions at the Large Hadron Collider.

The results of a number of studies have demonstrated the promise of adding intrahepatic arterial selective internal radiotherapy (SIRT) to chemotherapy for patients with liver metastases from colorectal cancer; however, the frequent progression of extrahepatic metastases observed in patients treated with SIRT in the SIRFLOX trial call the potential overall benefit of this approach into question.

The quark structure of the f₀(980) hadron is still unknown after 50 years of its discovery. Here, the CMS Collaboration reports a measurement of the elliptic flow of the f₀(980) state in proton-lead collisions at a nucleon-nucleon centre-of-mass energy of 8.16 TeV, providing strong evidence that the state is an ordinary meson.

Batlle and colleagues develop an organoid platform for functional antibody screening and identify a therapeutic bispecific antibody that binds EGFR and LGR5 and that shows efficacy across epithelial tumor patient-derived xenograft models in vivo.

Analysis of 2,170 SARS-CoV-2 sequences from the first wave of the COVID-19 epidemic in Spain provides insights into transmission patterns and the effects of lockdown on the emergence of new variants.

The CMS Collaboration reports the study of three simultaneous hard interactions between quarks and gluons in proton–proton collisions. This manifests through the concurrent production of three J/ψ mesons, which consist of a charm-quark–antiquark pair.

Contrary to the view that urbanization is a major driver of the global rise in obesity, the global increase in body-mass index is shown to be mostly due to increases in the body-mass indexes of rural populations.

Conventional models of transistors are not applicable to devices made from nanomaterials because their operation is dominated by gate-dependent transmission through a Schottkybarrier. Here, the authors develop an analytical model and compare it to data taken from ultrathin silicon field-effect transistors.

The failure of chemotherapy in colorectal cancer is currently unclear. Here, the authors show that upon sub-lethal dose of chemotherapy wild-type p53 colorectal cancers acquire a quiescence-like phenotype and a YAP-dependent fetal-like intestinal stem cell state associated with a higher metastatic activity and poor prognosis in patients.

Nitrogen fixation in oceans is facilitated by associations between marine phytoplankton and cyanobacteria such as UCYN-A. Here, Cornejo-Castillo et al. show that UCYN-A diversified in the late Cretaceous under strong purifying selection to become lineage-specific symbiont partners with different prymnesiophytes.

The CMS Collaboration reports evidence for off-shell Higgs boson contributions in the production of Z boson pairs, and measures the width of the Higgs boson, which is inversely related to its lifetime.

The most up-to-date combination of results on the properties of the Higgs boson is reported, which indicate that its properties are consistent with the standard model predictions, within the precision achieved to date.

Body size is hypothesised to be a major determinant of β-diversity in passively-dispersing marine organisms. Here, Villarino et al. show that plankton body size determines rates of dispersal along marine currents, with shorter dispersal and higher species spatial turnover in larger organisms.

Malumbres and colleagues reveal that mitotic arrest is accompanied by reduced mitochondrial mass and oxidative respiration resulting in activation of AMPK and induction of glycolysis to promote cell survival.

Macroalgae can be transported across the open ocean, and substantial amounts can reach the seafloor at 4,000 m depth, according to analyses of metagenome data from global expeditions. Macroalgae are a potentially important oceanic carbon sink globally.

Genetic and Structural analysis of COVID patients cohort reveals a correlation between mitochondrial haplogroup and SARS-CoV-2 severity.

Analysis of the spread of the 20E (EU1) variant of SARS-CoV-2 through Europe suggests that international travel and insufficient containment, rather than increased transmissibility, led to a resurgence of infections.

Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality.

Inhibition of activated BRAF has been ineffective in colon cancers with the mutation; here, this is shown to be due to the feedback activation of the epidermal growth factor receptor (EGFR) in response to BRAF inhibition.

An international consortium of colorectal cancer researchers undertakes a large-scale data sharing project to achieve a consensus molecular classification of colorectal cancers.

Combined analysis of proton-proton collision data from the Large Hadron Collider at CERN by the CMS and LHCb collaborations leads to the observation of the extremely rare decay of the strange B meson into muons; the result is compatible with the standard model of particle physics, and does not show any signs of new physics, such as supersymmetry.

Silvia Acinas et al. report the Malaspina Gene Database, a gene catalogue from deep ocean microbes and the Malaspina Deep Metagenome-Assembled Genomes (MAGs) which is made publicly available. The analysis of the metabolic pathways within these MAGs sheds light on the composition and of the strategies these microbes use to survive the deep ocean microbiome.
