Social interactions are known to guide behaviour, but how different species represent social stimuli is poorly understood. In this study, the authors demonstrate how social cues in the larval zebrafish suppress an oxytocinergic circuit, which regulates avoidance and feeding behaviour.

Reduced glomerular filtration rate (eGFR) is a hallmark of chronic kidney disease. Here, Pattaro et al. conduct a meta-analysis to discover several new loci associated with variation in eGFR and find that genes associated with eGFR loci often encode proteins potentially related to kidney development.

Caroline Fox and colleagues report results of a large genome-wide association meta-analysis and replication study for indices of renal function. Their work identifies 13 new loci associated with renal function and 7 loci associated with creatinine production and secretion.

Rapamycin (also known as sirolimus) is a potent immunosuppressive drug that is often used after organ transplant to prevent rejection, but it also can cause kidney dysfunction. Fabiola Terzi and her colleagues now show this side effect of rapamycin is due to targeting of mTORC2 and suppression of AKT2 activity in podocytes. They also show that AKT2 normally acts to maintain podocyte viability and structure during chronic kidney disease.

Trans-ancestry meta-analysis of estimated glomerular filtration rate (eGFR) from 1,046,070 individuals identifies 264 associated loci, providing a resource of molecular targets for translational research of chronic kidney disease.

Derek Mann and his colleagues have found that experimental induction of liver fibrosis in male rats results in an epigenetic modification of the chromatin in their sperm such that their offspring have a more mild wound-healing response to hepatic fibrogenic insults. The mechanism responsible for this phenomenon is not clear, but it seems to involve a yet unidentified soluble factor released by myofibroblasts that act on either the germ cells or mature sperm.

A PI3KCA inhibitor reverses symptoms in a mouse model of PROS/CLOVES syndrome, which results from gain-of-function mutations in PI3KCA, and produces improvements in patients with PROS/CLOVES syndrome.

Massive hydropower expansion in the global south repeats unsustainable past social and environmental harms, raising questions about how to govern these projects effectively. This Review highlights shifting and evolving global dynamics, and identifies opportunities for more just and strategic hydropower governance.

X-chromosomal genetic variants are understudied but can yield valuable insights into sexually dimorphic human traits and diseases such as chronic kidney disease (CKD). Here, the authors perform a sex-stratified, cross-ancestry X-chromosome-wide association meta-analysis of seven kidney-related traits, with results including identification of four novel loci associated with the CKD-defining trait eGFR.

A transancestral exome-wide association study for body-fat distribution identifies protein-coding variants that are significantly associated with waist-to-hip ratio adjusted for body mass index.

Genome-wide association studies (GWAS) have become a key tool to discover genetic markers for complex traits; however, environmental factors that interact with genes are rarely considered. Here, the authors conduct a GWAS of obesity traits, and find that smoking may alter genetic susceptibilities.

Inbreeding depression has been observed in many different species, but in humans a systematic analysis has been difficult so far. Here, analysing more than 1.3 million individuals, the authors show that a genomic inbreeding coefficient (FROH) is associated with disadvantageous outcomes in 32 out of 100 traits tested.

Analysing camera-trap data of 163 mammal species before and after the onset of COVID-19 lockdowns, the authors show that responses to human activity are dependent on the degree to which the landscape is modified by humans, with carnivores being especially sensitive.

Yang et al. demonstrate that inhibition of early-acting autophagy genes in neurons extend C. elegans lifespan, improve neuronal proteostasis and increase exopher formation mediated by the autonomous WD40 domain-related function of ATG-16.2.

Elevated intraocular pressure (IOP) is a heritable risk factor for primary open angle glaucoma. Using forward mouse genetics, cell biology, pharmacology and human genetic data, the authors identify CACNA2D1 as an IOP risk gene that can be therapeutically targeted by the drug pregabalin in animal models.

Meta-analysis of genome-wide association studies on Alzheimer’s disease and related dementias identifies new loci and enables generation of a new genetic risk score associated with the risk of future Alzheimer’s disease and dementia.

Growth of the mammalian heart is controlled by Hippo signalling but how this is regulated is unclear. Here, the authors show that Fat4 (an atypical cadherin) acts upstream of Hippo signalling and Fat4 mutant mice have thicker myocardium, which is mediated by the scaffold Amot1 and transcription factor Yap1.

Large genome-wide meta-analysis of clinically diagnosed late-onset Alzheimer’s disease (LOAD) from 94,437 individuals identifies new LOAD risk loci and implicates Aβ formation, tau protein binding, immune response and lipid metabolism.

A trans-ancestry genome-wide association study of serum urate levels identifies 183 loci influencing this trait. Enrichment analyses, fine-mapping and colocalization with gene expression in 47 tissues implicate the kidney and liver as key target organs and prioritize potential causal genes.

An integrated analysis of de novo and inherited coding variants in 42,607 individuals with autism spectrum disorder identifies 60 risk genes of which five have not previously been associated with neurodevelopmental disorders.

Single-cell analysis of lung, heart, kidney and liver autopsy samples shows the molecular and cellular changes and immune response resulting from severe COVID-19 infection.

Vaccination against COVID-19 has shown activation of different immune cell types. Here the authors characterise the immune response to the SARS-CoV-2 mRNA vaccine using longitudinal CyTOF single cell approaches to characterise antigen specific B and T-cell responses promoted by this vaccine.

In early type 2 diabetes, “induction” with short-term insulin therapy followed by “maintenance” with metformin can stabilize beta-cell function. The authors show that initial reversibility of beta-cell dysfunction followed by preserved hepatic insulin sensitivity determine sustained stabilization.

Combining a GLP-1 receptor agonist, to increase endogenous beta cell function, with exogenous insulin is a possible therapeutic option for the treatment of type 2 diabetes. Here, the authors show adding exenatide to basal insulin in early type 2 diabetes does not further enhance underlying pancreatic beta-cell function or the capacity to achieve diabetes remission, but may yield on-treatment glycemic benefits.

Müller-Tidow and colleagues demonstrate that hotspot DNMT3A mutations found in clonal hematopoiesis and acute myeloid leukemia render cancer cells sensitive to the DNMT1 inhibitor azacitidine through focal DNA demethylation, viral mimicry and interferon activation.
