A phase 2 randomized controlled trial of ustekinumab in 72 adolescents with recent-onset type 1 diabetes showed that treatment was well tolerated and β-cell function was 49% higher in the intervention group compared to the placebo arm after 12 months.

Dietary quality is reported at the global, regional and national level across 185 countries. Though diet quality increased modestly since 1990 at the global level, in South Asia and Sub-Saharan Africa it did not improve. In some regions, children’s dietary quality is lower than that of adults.

Imaging of the mantle transition zone beneath the Lesser Antilles shows a basalt-rich region within the subducting slab near the proposed location of a subducted extinct spreading ridge, implying ancient tectonics play a role in influencing slab trajectories.

A genome-wide association meta-analysis study of blood lipid levels in roughly 1.6 million individuals demonstrates the gain of power attained when diverse ancestries are included to improve fine-mapping and polygenic score generation, with gains in locus discovery related to sample size.

A comprehensive database of summer data reveals long-term changes in the vertical distribution of water masses on the Northeast Greenland Shelf, which will be important for driving ecosystem change through altered stratification and nutrient supply.

This large integrated analysis of the KRAS^G12C inhibitor sotorasib clinical efficacy biomarkers from the phase 2 CodeBreaK 100 and phase 3 CodeBreaK 200 trials shows that low expression of TTF-1 and high expression of NRF2 determine anti-tumor efficacy of sotorasib in non–small-cell lung cancer.

An analysis based on data from the Global Dietary Database shows mean animal-sourced food intakes among children and adolescents increased modestly from 1990 to two portions per day in 2018, but remain low in sub-Saharan Africa, India and Bangladesh.

Induction of the cis form of phosphorylated tau (cis P-tau) has previously been shown to occur in animal models of traumatic brain injury (TBI), and blocking this form of tau using antibody was beneficial in a rodent model of severe TBI. Here the authors show that cis P-tau induction is a feature of several different forms of TBI in humans, and that administration of cis P-tau targeting antibody to rodents reduces or delays pathological features of TBI.

The idea of the United States government footing the bill to prevent the American population falling sick makes President Ford's request for funds to attempt a mass inoculation against flu something more than a medical issue in this election year. From Washington, Colin Norman gives the background

The transient elevation in protein translation during early-adulthood in Drosophila imposes long-lasting negative impacts on future aging trajectories by triggering proteostatic dysfunction at old ages.

A massive galaxy observed with the JWST indicates that the bulk of its stars formed within the first 500 million years of the Universe.

Panos Deloukas, Nilesh Samani and colleagues report a large-scale association analysis using the Metabochip array in 63,746 coronary artery disease cases and 130,681 controls. They identify 15 susceptibility loci, refine previous associations and use network analysis to highlight biological pathways.

The authors find that mice fed a diet with reduced levels of branched-chain amino acids have improved metabolic health, and in males but not females, lifelong feeding of such a diet reduces frailty and extends life span.

The Food and Drug Administration last week issued a set of regulations designed to help combat a growing scandal over drug testing in the United States. Colin Norman reports from Washington

The Office of Management and Budget always exerts a powerful influence over the US government. But it is now taking a higher profile, and a stronger interest in science. Should researchers be alarmed? Colin Macilwain reports.

Genome-wide association and fine-mapping analyses in ancestrally diverse populations implicate candidate causal genes and mechanisms underlying type 2 diabetes. Trans-ancestry genetic risk scores enhance transferability across populations.

Analyses of genome and exome sequencing data identify rare coding and structural variants associated with atrial fibrillation and highlight genetic links between atrial fibrillation and cardiomyopathies.

Patricia Munroe, Christopher Newton-Cheh, Andrew Morris and colleagues perform association studies in over 340,000 individuals of European ancestry and identify 66 loci, of which 17 are novel, involved in blood pressure regulation. The risk SNPs are enriched for cis-regulatory elements, particularly in vascular endothelial cells.

Penetrance of variants in monogenic disease and clinical utility of common polygenic variation has not been well explored on a large-scale. Here, the authors use exome sequencing data from 77,184 individuals to generate penetrance estimates and assess the utility of polygenic variation in risk prediction of monogenic variants.

Recent estimates of sugar-sweetened beverages (SSBs) intake are generally unavailable. Here the authors show a global SSBs intake of 2.7 servings/week in 2018 in adults (range: 0.7 South Asia, 7.8 Latin America/Caribbean); intakes were higher among males, younger, more educated, and urban adults.

In a multicenter research program coordinated by the International Mouse Phenotyping Consortium, Spielmann et al. analyze the cardiac function and structure in ~4,000 monogenic mutant mice and identify 705 mouse genes involved in cardiac function, 75% of which have not been previously linked to cardiac heritable disease in humans. Using the UK Biobank human data, the authors validate the link between cardiovascular disease and some of the newly identified genes to illustrate the resource value and potential of their mutant mouse collection.

Timothy Frayling, Joel Hirschhorn, Peter Visscher and colleagues report a meta-analysis of genome-wide association studies for adult height in 253,288 individuals. They identify 697 variants in 423 loci significantly associated with adult height and find that these variants cluster in pathways involved in growth and together explain one-fifth of the heritability for this trait.

Microbiota impacts all major aspects of physiology, but little is known about its effects on age-related changes in immune responses. Here the authors show that gut microbiota transfer between adult and old mice increases local but not systemic germinal centre responses regardless of age directionality.

Compound MMV006833 inhibits ring-stage development of Plasmodium falciparum. Here, the authors show that it targets lipid transfer enzyme PfSTART1 and prevents PfSTART1 from expanding the vacuole membrane encasing the parasite after red blood cell invasion, thereby blocking parasite growth.

Cardiovascular and metabolic risk factors (CVM) impact brain structure and increase dementia risk. Here, the authors developed and validated machine learning models to measure the neuroanatomical changes in people with cardiovascular and metabolic diseases that are cognitively unimpaired.

Stem rust is an important disease of wheat and resistance present in some cultivars can be suppressed by the SuSr-D1 locus. Here the authors show that SuSr-D1 encodes a subunit of the Mediator Complex and that nonsense mutations are sufficient to abolish suppression and confer stem rust resistance.

Dural-associated lymphoid tissues are lymphoid structures around vascular hubs in the dura mater that sample antigens and rapidly support humoral immune responses after local pathogen challenge.

How the carbon stocks of the Arctic–Boreal Zone change with warming is not well understood. Here the authors show that wildfires and large regional differences in net carbon fluxes offset the overall increasing CO₂ uptake.

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.

Analysis of mitochondrial genomes (mtDNA) by using whole-genome sequencing data from 2,658 cancer samples across 38 cancer types identifies hypermutated mtDNA cases, frequent somatic nuclear transfer of mtDNA and high variability of mtDNA copy number in many cancers.

Impaired Aβ clearance in late-onset Alzheimer’s disease (AD) affects progression. Here, the authors show that CD14 + CD16+ monocytes carry Aβ in peripheral circulation and CSF in AD, suggesting a role in Aβ clearance.

An assessment of blue carbon strategies in Belize shows how quantifying fisheries, tourism and coastal risk co-benefits alongside carbon benefits can inform spatial and temporal target setting for nationally determined climate contributions that simultaneously provide societal benefits.

Modelling reveals large swathes of land in tropical grassy and dry forest biomes that are climatically suitable for commercial plantations of oil palm and would comply with current zero-deforestation commitments, but where conversion to oil palm would, in many locations, cause loss of habitat and biodiversity.

After a period of rapid growth, enrolment in higher education in the United States is levelling off. The result is likely to be an increasingly bleak academic job market for scientists and engineers with PhD degrees and the trend has major implications for the nature of graduate education.

In this work, the authors present E. coli PanSelect, a hybrid selection method for enriching E. coli from low-abundance microbiota, and apply it to stool samples from recurrent UTI sufferers, revealing distinct E. coli transcriptional profiles
