In a quasi-experimental, pre–post-implementation study involving 51,760 hospitalizations, an electronic health record-based risk prediction model informed clinicians of patients needing consultation on opioid use disorder and decreased readmissions to the hospital, without increasing referral rates and with promising cost-effectiveness results.

The authors use Patch-seq and electron microscopy datasets to relate synaptic connectivity to the transcriptomic cell type of different types of inhibitory neuron.

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.

A rare case of asymptomatic dominantly inherited Alzheimer’s reveals confined tau pathology and unique proteomic features, highlighting potential resilience mechanisms decades beyond expected onset.

This study reports that nuclear speckle constituents have two expression states in cancer correlating with patient survival and HIF-2α functional programs. HIF-2α mediates nuclear speckle association of key genes activated in renal cancer.

The authors reveal that the chromatin architectural proteins CTCF and RAD21 organize DNA around nuclear speckles to enhance gene induction. This structural organization, when disrupted as in Cornelia de Lange syndrome, impairs key gene functions, providing insight into potential disease mechanisms.

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.

Transancestral GWAS meta-analysis in 160,420 individuals identifies 139 loci associated with refractive error, including myopia. Newly identified genes implicate pathways involved in eye growth and light signaling cascades.

Pediatric brain cancers are lethal malignancies driven by less-differentiated stem-like cells. Here the authors show that these cells exhibit distinct mitochondrial metabolism programs with targetable vulnerabilities.

This study supports neurofilament light chain protein (NfL) in both cerebrospinal fluid (CSF) and blood as an early marker of neurodegeneration in Alzheimer’s disease but suggests that NfL in CSF may be better suited than blood for monitoring clinical trial outcomes in symptomatic patients.

Analyses of real-world evidence from digital clinical practice data provide important insights for healthcare decision makers. Here, authors test reproducibility of 150 peer-reviewed studies, reporting strong reproducibility, which could be further improved through more complete reporting in future original studies

Multi-ancestry genome-wide association meta-analysis identifies new risk loci for CAC. Functional evidence implicates candidate causal genes as regulators of smooth muscle cell-mediated calcification.

A fluorophore with peak excitation and emission wavelengths in the near-infrared window allows for the microscopic imaging of amyloid-β and tau aggregates through the intact skull in mouse models of Alzheimer’s disease.

A dataset of 3D images from more than 200,000 human induced pluripotent stem cells is used to develop a framework to analyse cell shape and the location and organization of major intracellular structures.

Ruth Loos and colleagues report results of a large genome-wide association study for body mass index. They identify 18 new loci associated with this trait, some of which map near key hypothalamic regulators of energy balance.

Insufficient AHR activation has been suggested in SLE, and augmenting AHR activation therapeutically may prevent CXCL13⁺ T_PH/T_FH differentiation and the subsequent recruitment of B cells and formation of lymphoid aggregates in inflamed tissues.

Emerging SARS-CoV-2 variants raise concerns on immune evasion. Here, the authors evaluate the neutralization efficiency of COVID-19 mRNA vaccinee sera against representative viruses of 13 WHO-designated SARS-CoV-2 variants of concern/interest.

Antigenic variation of influenza A viruses necessitates the annual reformulation of vaccines. Kanekiyo et al. develop a mosaic nanoparticle vaccine against influenza virus that is able to elicit neutralizing antibodies that span nearly 100 years of variation of influenza A virus.

The Vertebrate Genome Project has used an optimized pipeline to generate high-quality genome assemblies for sixteen species (representing all major vertebrate classes), which have led to new biological insights.

Most reagents designed to deliver cargo into cells are cationic and so cannot deliver cationic cargo. Here the authors show that pretreating cells with the anionic polymer poly(propylacrylic acid) facilitates the uptake and endosomal escape of a wide variety of cationic cargo in numerous cell types.

Synaptic structures disintegrate and fragment as ageing progresses. Here the authors find that miniature neurotransmission is required to maintain adult motor synapse structures in Drosophila and that increasing miniature events can preserve motor ability during ageing.

Cecilia Lindgren and colleagues report results of a large-scale genome-wide association study for waist-to-hip ratio, a measure of body fat distribution. They identify 13 new loci associated with this trait, several of which show stronger effects in women than in men.

Age at voice-breaking is used to determine puberty timing in men, recall of which is considered less accurate than age at first menarche in women. Here, the authors perform multi-trait GWAS for male puberty timing by including both age at voice breaking and age of first facial hair for improved phenotype definition and power.

Proteomic analysis of cerebrospinal fluid from individuals with autosomal dominant Alzheimer’s disease reveals how this complex and chronic disease evolves over many decades.

IL-2 has been used to expand regulatory T (Treg) cells for treating inflammatory disorders. Here the authors test an engineered IL-2 mutein, delivered subcutaneously as mRNA, to show its increased specificity for activating and expanding Treg cells in both rodents and non-human primates, and to demonstrate its ability to suppress autoimmunity in mouse models.

Analyses of epigenomic datasets spanning transitions from normal prostate epithelium to localized prostate cancer to metastases show that latent developmental programs are reactivated in metastatic disease and that prostate lineage-specific regulatory elements are strongly enriched for prostate cancer risk heritability.

Hydropower generation in the Nile River Basin is vulnerable to climatic changes. Here, the authors assess infrastructure resilience of the Eastern African power pool (EAPP) to the effects of a changing climate and suggest that failing to climate-proof infrastructure investments can result in significant electricity price fluctuations.

Distributed multi-omic digitization of clinical specimen across multiple sites is a prerequisite for turning molecular precision medicine into reality. Here, the authors show that coordinated proteotype data acquisition is feasible using standardized MS data acquisition and analysis strategies.

The spatial organization of the genome within the nucleus impacts many processes. Here the authors combine oligo-based DNA FISH with single-molecule super-resolution microscopy to image single-copy genomic regions and, taking advantage of SNPs, distinguish allelic regions of homologous chromosomes.

Drugs that block calcium channels reduce pain, but they can cause unwanted side effects. Now, Rajesh Khanna and his colleagues show that a peptide that inhibits the interaction between a calcium channel and a protein called CRMP-2 that activates the channel can reduce pain in animals without the side effects of the channel blocker drugs.

Ticks transmit a large number of pathogens that cause human diseases. Here, the authors sequence the genome of the tick Ixodes scapularisand uncover expansion of genes associated with parasitic processes unique to ticks and tick-host interactions.

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.
