The prelimbic region of the prefrontal cortex is involved in goal-directed action. Here the authors investigate the function of the prelimbic pathways projecting along the anterior posterior striatal axis in value based decision making in male mice.

DeBerge, Glinton et al. demonstrate that allograft inflammatory factor 1 promotes inflammatory glycolytic reprogramming in cardiac macrophages, leading to adverse remodeling and progression to heart failure after myocardial infarction.

Graphene oxide is a promising material for molecular separation technologies. Here, the authors propose a realistic staggered stacking structure that plays a crucial role in H/D recognition in water adsorption, as well as high mobilities of water.

Integrated multi-omic analyses using samples from the TRACERx study highlight cross-talk between DNA hypermethylation and genomic lesions in non-small cell lung cancer.

The application of phage therapy for multidrug-resistant infections is mainly limited to personalized therapy due to the narrow host range of individual phages. Here, Kim et al. identify groups of phages that use non-redundant receptors, and present a blueprint for the development of effective, broad-spectrum phage-antibiotic combinations.

Jonathan Thomas and colleagues present real-time plasma effector measurements during wound treatment. In- situ monitoring enables precise plasma device control, advancing precision plasma medicine and supporting clinical translation.

Jung et al. show that shelter experience boosts dopamine release in the nucleus accumbens, generating a goal-location memory. Reactivating a neuronal ensemble developed from shelter experience enables memory-guided navigation to the goal during escape.

Yang and colleagues report that MAIT cells are present in the meninges where they play an essential role in repressing tissue ROS accumulation and preserving meningeal barrier integrity.

The authors examine wisdom perception in convenience samples from twelve countries. They observe two latent dimensions that guide participant’s evaluation of wisdom-related characteristics in others and the self—reflective orientation and socio-emotional awareness, which were consistent across the studied cultural regions.

Analysing camera trap data from >26,000 stations and >158,000 vegetation plots across 12 ecoregions in India, the authors find a positive relationship between megaherbivore abundance and native plant species richness and abundance, but reductions in alien plant species abundance.

Biocompatible core–shell quantum dots and superconducting nanowire single-photon detector enable non-invasive one-photon excitation fluorescence imaging at 1,880 nm for in vivo imaging at 1,100 μm depth.

FRET sensors hardly achieve visualization of spatiotemporal dynamics of protein activity in vivo. Here the authors present intensiometric small GTPase biosensors based on dimerization-dependent fluorescent proteins that enable monitoring of activity of small GTPases in the brains of behaving mice at a single spine resolution.

Efficacious cancer vaccines can be made via the cryogenic silicification of tumour cells followed by the decoration of the silicified surface with pathogen-associated molecular patterns.

Proximity between mitochondria and endoplasmic reticulum regulates mitochondria fitness and is adversely affected by tissue ischemia. This work reveals that Diaphanous1-Mitofusin2 interaction regulates this proximity and impairs recovery in ischemia.

Patients with diabetes could benefit from cell-based insulin therapy, but the supply of human islet tissue is limited. A study now reports an approach in which human-pluripotent-stem-cell-derived islet β-cells are purified and re-aggregated to generate cells that more closely resemble mature human β-cells.

Chen et al. find that cerebellar Purkinje cells directly inhibit neurons in parabrachial nuclei that in turn influence many forebrain regions. This alternative output pathway could enable the cerebellum to regulate emotions, anxiety, aggression and affect.

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).

A study examining bacterial gene expression in human-derived samples identifies a gene encoding a small RNA and describes how it orchestrates the transition between chronic and acute infection in Pseudomonas aeruginosa.

Label-free imaging of the endogenous pigment lipofuscin at near-infrared and shortwave-infrared wavelengths enables the longitudinal monitoring of liver injury in mice and in biopsied human livers.

Microporous annealed-particle degradable scaffolds have been developed and shown to induce type 2 innate and adaptive immune response that facilitated skin wound healing.

A consensus cell type atlas for the fly brain provides both an intellectual framework and open-source toolchains for brain-scale comparative connectomics.

COVID-19-related non-pharmaceutical interventions impacted the circulation of other pathogens. Here, the authors compile a global viral activity dataset and compare the timing of resurgence of seven common respiratory viruses following the relaxation of interventions across different geographical regions.

Chandelier cells organize neural coding and mediate learning by establishing inhibitory circuit motifs over individual pyramidal neurons and suppressing irrelevant activity via adaptive axo-axonic synaptic plasticity, subserving efficient computation.

Temporal multi-omic analysis of tissues from rats undergoing up to eight weeks of endurance exercise training reveals widespread shared, tissue-specific and sex-specific changes, including immune, metabolic, stress response and mitochondrial pathways.

Li et al. analyzed structural connectivity of deep brain stimulation electrodes in 50 patients suffering from obsessive-compulsive disorder operated at four centers. Connectivity to a specific tract within the anterior limb of the internal capsule was associated with optimal treatment response across cohorts, surgeons and centers.

Quantifying lipid and water content in tissues non-invasively is difficult, and no method exists to quantify lipids in blood non-invasively. Here the authors develop an imaging approach called shortwave infrared meso-patterned imaging (SWIR-MPI) to detect and spatially map tissue water and lipids in preclinical models.

Psoriasis is a partially heritable skin disorder, the genetic basis of which is not fully understood. Here, the authors use genome-wide association meta-analysis to discover psoriasis susceptibility loci and genes, which encode existing and potential new drug targets.

A method, RARE-seq, for sensitive detection of cell-free RNAs in blood is demonstrated to have diverse clinical applications including diagnosing and characterizing human cancers, and tracking response to RNA therapeutics.

The role that the striatum plays in tracking the association between actions and combinations of rewarding and aversive outcomes remains unclear. Here, by using both calcium imaging in mice and reinforcement learning models, the authors find that individual striatal neurons can encode associations between actions and multiple, sometimes conflicting, outcomes.

A machine-learning tool can predict the distribution of histone post-translational modifications using nascent transcription data. Inhibiting transcription impacts H3K4me3, H3K27ac and H3K27me3 dynamics.
