Protein sequence and structural similarities in large databases are rapidly identified using machine learning.

SARS-CoV-2 infection is associated with an increased risk of arterial and venous thrombotic events. Here, the authors investigate the degree to which this association is modified by virus variant and vaccination using electronic health record data for ~18 million adults in England.

Genome-wide association analyses identify new risk loci for heart failure and its subtypes, extending understanding of the underlying biological pathways and disease mechanisms.

Quantum mechanics predicts that objects can simultaneously exist in a superposition of two states. Kneeet al.propose and demonstrate experimentally a protocol which fully confirms this prediction, by testing the so-called Leggett–Garg inequality in a non-invasive manner.

The coherence lifetime of a material system to be used in quantum information protocols has to be long enough for several quantum operations to occur before the system loses its quantum coherence. The spins of impurities in silicon have been shown to have coherence lifetimes up to tens of milliseconds, but now all records are beaten with those in high-purity silicon reaching a few seconds.

This study presents a predictive equation for total energy expenditure derived from doubly labelled water measurements. Applying this equation to two large datasets (the National Diet and Nutrition Survey and National Health and Nutrition Examination Survey) shows that the misreporting of total energy intake is greater than 50%, with important implications for macronutrient availability.

This paper provides an analysis or rainfall changes that integrates human-based and instrument-based observations, identifying regions of agreement and disagreement, and providing insights on how traditional ecological knowledge can complement instrumental indices.

Clinical management of COVID-19 in resource-poor settings has distinct challenges and detailed patient characterisation is needed. Here, the authors describe the clinical and immunological profiles of patients at a hospital in Malawi with confirmed and suspected COVID-19.

Warming and drying from deforestation could amplify carbon storage losses in tropical remaining forests. Here the authors report this value to be extra 5.1% in the Amazon and 3.8% in Congo as compared to the direct biomass loss from deforestation.

Chronic lymphocytic leukemia is a highly inheritable cancer. Here the authors conduct a metaanalysis of four genome-wide association studies and identify three novel loci located near EOMES, SERPINB6 and LPPassociated with risk of this disease.

A readout scheme for quantum devices, which is inspired by one-transistor–one-capacitor dynamic random access memory and consists of CMOS field-effect transistors and quantum dots, could reduce the number of input lines per qubit and allow large-scale device arrays to be addressed.

Right-sided colorectal cancer (rCRC) has a different mutational spectrum to the left-sided counterpart. Here the authors develop a mouse model of rCRC that recapitulates human BRAF-mutant rCRC and show that loss of TGFβ-receptor signalling and inflammation induce the development of colonic tumours with a foetal-like phenotype.

Developmental disorders (DDs) are more prevalent in males, thought to be due to X-linked genetic variation. Here, the authors investigate the burden of X-linked coding variants in 11,044 DD patients, showing that this contributes to ~6% of both male and female cases and therefore does not solely explain male bias in DDs.

Susan Slager and colleagues report a meta-analysis of genome-wide association studies for chronic lymphocytic leukemia (CLL). They identify nine loci newly associated with CLL.

Genetic analysis in mice selected for leanness has identified thiosulfate sulfurtransferase as a target for the treatment of diabetes.

Chromodomain Helicase DNA-binding (CHD) proteins have been implicated in neurodevelopmental processes. Here, the authors identify missense variants in CHD3 that disturb its chromatin remodeling activities and cause a neurodevelopmental disorder with macrocephaly and speech and language impairment.

Unrestrained Src signalling can be toxic for cancer cells. Wilkinson, Frame and colleagues show that active Src is sequestered in autophagosomes in cancer cells. Inhibition of autophagy induces cancer cell death.

Genome sequence data from colorectal tumours show how adenomas progress to carcinomas on the fitness landscape.

By integrating healthcare and exome-sequencing data from parent–offspring trios of patients with developmental disorders, 28 genes that had not previously been associated with developmental disorders were identified.

Chronic lymphocytic leukaemia has a hereditary component, much of which remains to be identified. Here, the authors perform a genome-wide association study and find new risk loci for the disease, which are associated with genes involved in immune function.

Clock transitions, typically observed in arrays of trapped atoms, can now be observed for electron spins in silicon doped with bismuth.

Marginal zone lymphoma (MZL) is a common subtype of B-cell non-Hodgkin lymphoma. Here the authors carry out a two-stage genome-wide association study in over 8,000 Europeans and identify two new MZL risk loci at chromosome 6p, implicating the major histocompatibility complex in the disease for the first time.

Environmental exposures shape patterns of selection for mutations in clonal hematopoiesis. Cancer therapies promote the growth of clones with mutations that are strongly enriched in treatment-related myeloid neoplasms.

Christine Skibola and colleagues identify variants at 6p21.32 associated with risk of follicular lymphoma, providing further support that variation in the MHC region influences risk of this disease. They also replicate previously reported risk variants for chronic lymphocytic leukemia.

The InSight lander has expanded our knowledge of the atmosphere of Mars by observing various phenomena, including airglow, bores, infrasound and Earth-like turbulence.

Studying dynamic processes in mechanobiology has been challenging due to lack of appropriate tools. Here, the authors present an interference-based method, illuminated via two rapidly alternating wavelengths, which enables real-time mapping of nanoscale forces with sub-second mechanical fluctuations.

As phase 1 of the Earth Microbiome Project, analysis of 16S ribosomal RNA sequences from more than 27,000 environmental samples delivers a global picture of the basic structure and drivers of microbial distribution.

Cities may host surprisingly diverse and functionally distinct biological communities. This global analysis on 5302 vertebrate and invertebrate species finds evidence of 4 trait syndromes in urban animal assemblages, modulated by spatial and geographic factors.

Wu et al. utilize multiparametric analysis of early-stage human NSCLC to characterize a population of Vδ1 T cells displaying a resident memory and effector memory phenotype, which were associated with ongoing remission.

Bennu’s surface presents evidence of a variety of particle sizes, from fine regolith to metre-sized boulders. Its moderate thermal inertia suggests that the boulders are very porous or blanketed by thin dust. Bennu’s boulders exhibit high albedo variations, indicating different origins and/or ages.

Colorectal tumors with mutated KRAS and APC require the amino acid transporter SLC7A5 to drive tumorigenesis. Mechanistically, SLC7A5 drives transcriptional and metabolic reprogramming by maintaining intracellular amino acid levels, leading to enhanced protein synthesis.

Signatures of phyllosilicate-like hydrated minerals are widespread on Bennu’s surface, indicating significant aqueous alteration. The lack of spatial variations in the spectra down to the scale of ~100 m indicates both a relatively uniform particle size distribution and a lack of compositional segregation, possibly due to surficial redistribution processes.

The Cancer Genome Atlas presents an integrative genome-wide analysis of genetic alterations in 279 head and neck squamous cell carcinomas (HNSCCs), which are classified by human papillomavirus (HPV) status; alterations in EGFR, FGFR, PIK3CA and cyclin-dependent kinases are shown to represent candidate targets for therapeutic intervention in most HNSCCs.
