Polygenic scores for body mass index and obesity constructed using data from 5 million people with different ancestries were associated with distinct weight gain trajectories from early childhood to adulthood.

Whole-genome sequencing, transcriptome-wide association and fine-mapping analyses in over 7,000 individuals with critical COVID-19 are used to identify 16 independent variants that are associated with severe illness in COVID-19.

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).

How axolotl salamanders know what portion of the limb to regenerate remains a mystery. In this article, the authors show that precise retinoic acid degradation is critical for instructing regeneration of the appropriate limb segment.

An expert-elicitation process identifies current methodological barriers for monitoring terrestrial biodiversity, and how technological and procedural development of robotic and autonomous systems may contribute to overcoming these challenges.

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.

Protein tethers can bridge the actin cytoskeleton with cellular membranes. Here, the authors show that two members of the NETWORKED family, NET4A and NET4B, tether actin filaments and the tonoplast through interaction with RABG3b and are essential for actin reorganization during stomatal closure in plant immunity.

T cell responses can be generated to either pathogen infection or from priming with a vaccine. Here the authors compare T cell generation, phenotype and single cell transcriptome of participants vaccinated with a mpox vaccine or infected with the virus showing that the virus induced T cells showed more effective function and phenotype.

A large genome-wide association study of more than 5 million individuals reveals that 12,111 single-nucleotide polymorphisms account for nearly all the heritability of height attributable to common genetic variants.

The generation of a sustainable supply of erythroid progenitors is essential for the reliable production of anin vitroderived red blood cell clinical product. Here the authors immortalize early human erythroblasts to generate the first cell line capable of differentiation into functional adult reticulocytes.

Here, the authors show that reticulocytes derived from immortalized erythroblasts support invasion and development of Plasmodium falciparum and use CRISPR-mediated gene knockout and complementation of an invasion receptor to demonstrate utility of this model system for research in malaria invasion.

Whole-genome sequencing analysis of individuals with primary immunodeficiency identifies new candidate disease-associated genes and shows how the interplay between genetic variants can explain the variable penetrance and complexity of the disease.

A study of the evolution of the SARS-CoV-2 virus in England between September 2020 and June 2021 finds that interventions capable of containing previous variants were insufficient to stop the more transmissible Alpha and Delta variants.

A national prospective study of patients requiring hospitalization for COVID-19 demonstrates global cognitive deficits at 1 year, associated with elevated brain injury markers and reduced gray matter volume.

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.

A genome-wide association study of critically ill patients with COVID-19 identifies genetic signals that relate to important host antiviral defence mechanisms and mediators of inflammatory organ damage that may be targeted by repurposing drug treatments.

COVID-19 can be associated with neurological complications. Here the authors show that markers of brain injury, but not immune markers, are elevated in the blood of patients with COVID-19 both early and months after SARS-CoV-2 infection, particularly in those with brain dysfunction or neurological diagnoses.

The human brain is a distributed system composed of highly interconnected hubs. Here, patients undergoing a rare operation reveal the immediate impact and compensatory brain network changes that occur when a key hub is removed.

Whole-genome sequencing and phenotype data sharing are introduced in a national health system to streamline diagnosis and to discover coding and non-coding variants that cause rare diseases.

Exome-wide analysis identifies rare and low-frequency coding variants associated with body mass index. Gene-based meta-analysis and functional studies implicate 13 genes, eight of which are novel, and neuronal pathways as factors in human obesity.

The antibiotic enacyloxin IIa is assembled by a modular polyketide synthase, and released from it by condensation of the enacyloxin acyl chain with 3,4-dihydroxycyclohexane carboxylic acid. A multipronged approach shows the structural basis for recognition between the peptidyl carrier protein domain that bears the acyl chain and the non-ribosomal peptide synthetase condensation domain that ligates it with the carboxylic acid.

In cancer, interactions between treatment-sensitive and resistant cells can influence the effectiveness of therapies. Here, the authors use experimental and mathematical models to explore interactions between ER+ breast cancer cell lineages that are sensitive or resistant to CDK4/6 inhibition, revealing the role of facilitative growth.

Sera from vaccinated individuals and some monoclonal antibodies show a modest reduction in neutralizing activity against the B.1.1.7 variant of SARS-CoV-2; but the E484K substitution leads to a considerable loss of neutralizing activity.

Chronic infection with SARS-CoV-2 leads to the emergence of viral variants that show reduced susceptibility to neutralizing antibodies in an immunosuppressed individual treated with convalescent plasma.

The authors summarize the data produced by phase III of the Encyclopedia of DNA Elements (ENCODE) project, a resource for better understanding of the human and mouse genomes.

Using high-resolution fMRI in macaque monkeys, the authors demonstrate the existence of a topographic representation for temporal sound properties, which runs from dorsomedial to the ventralateral in the inferior colliculus. This is in addition to a previously reported representation of sound spectral properties (also found here), running approximately perpendicular to the temporal map.

Lucas and colleagues describe loss-of-function variants in the X-linked ETS transcription factor ELF4 in multiple unrelated male patients with early onset mucosal autoinflammation and inflammatory bowel disease (IBD)-like features.

Dissolved organic matter is persistent in soil owing to continuous consumption and transformation rather than owing to its recalcitrant molecular properties, according to analyses of molecular changes of dissolved organic matter as it passes through soil.

Investigation of variation in three cohorts has identified multiple genetic signals associated with the pregnancy-specific liver disorder, intrahepatic cholestasis of pregnancy, giving insight into the disease which can cause preterm birth and stillbirth.

Balezeau et al. find a primate homolog of the human language pathway within the auditory system of monkeys and apes. This discovery pushes back the human language pathway’s origin by about 20 million years and illuminates its remarkable evolutionary transformation.

This study uses functional magnetic resonance imaging in humans and monkeys to show similar ventral frontal and opercular cortical responses when processing sequences of auditory nonsense words. The study indicates that this frontal region is involved in evaluating the order of incoming sounds in a sequence, a process that may be conserved in primates.
