A device architecture based on indium arsenide–aluminium heterostructures with a gate-defined superconducting nanowire allows single-shot interferometric measurement of fermion parity and demonstrates an assignment error probability of 1%.

Zhu et al. compile a global N deposition database and find a shift in N deposition, with developing countries emerging as new hotspots. A strong link between economic development and N dynamics is identified, with important policy implications.

In this study of more than 6500 emergency department patients, symptoms consistent with Long COVID are reported by 38.9% of SARS-CoV-2 test-positive and 20.7% of test-negative patients three months after their visit. A documented SARS-CoV-2 infection increased the risk fourfold of reporting Long COVID symptoms.

Whipworms are large parasites causing chronic disease in humans and other mammals. Here, the authors show how larvae create tunnels inside the gut lining and reveal the early host response to infection via Isg15 in mice and murine caecaloids.

In this work, the authors describe immunisation of human antibody immune repertoire transgenic mice as a surrogate to define protective human antibody reactivity to clinically diverse, antibiotic resistant Acinetobacter baumannii.

Here, Kioko et al. describe a putative posttranscriptional RNA regulation mechanism involving secreted extracellular vesicles to maintain the intracellular steady-state RNA levels during the asexual blood stage of malaria parasites.

Two populations of neurons with distinct anatomy and receptor expression that convey information from the spinal cord to the brain have different functional properties with respect to touch and pain.

JWST/NIRSpec observations of Abell2744-QSO1 show a high black-hole-to-host mass ratio in the early Universe, which indicates that we are seeing the black hole in a phase of rapid growth, accreting at 30% of the Eddington limit.

The risks of major congenital anomalies associated with SARS-CoV-2 vaccination in early pregnancy are not well understood. Here, the authors conduct a population-based cohort study using electronic health records from Scotland and find no evidence of an association, supporting vaccine safety in pregnancy.

Reducing agricultural emissions during times of increasing food demand is a challenge. Research, using the UK as an example, now shows the technical mitigation potential of increasing agricultural yields, reducing farmed area and restoring habitats.

Lack of correct embryo transport can cause ectopic pregnancy. Here, the authors show that female mice lacking the adhesion G-protein coupled receptor Adgrd1 are infertile, due to embryos being trapped in the ampulla as the result of dysregulated oviductal fluid flow.

In vitro models to study the role of host genetics in the response to chlamydial infection are limited. Here, Yeung et al. show that macrophages derived from human induced pluripotent stem cells (which can be genetically manipulated) support chlamydial infection and can be used for this purpose.

Neural processing speed slows with age, but the relationship between this slowing and brain atrophy is unknown. Here, authors show that age-related functional brain differences in auditory and visual processing are partly due to structural differences in the distinct brain regions underlying these processes.

Ubiquitous mammalian enzymes can scavenge uracil analogs, leading to non-specific background in cell-type-specific RNA labeling. This work reveals the enzymes involved and describes the uridine/cytidine kinase 2 and 2′-azidouridine pair as a highly specific and non-toxic alternative.

Contact-dependent growth inhibition (CDI) is an important mechanism of bacterial competition. Here, Bartelli et al. show that proteolytic processing of a CDI toxin induces a conformational switch required for translocation into target bacteria.

Confining plasma and managing disruptions in tokamak devices is a challenge. Here the authors demonstrate a method predicting and possibly preventing disruptions and macroscopic instabilities in tokamak plasma using data from JET.

Systemic genome-led vaccinology and a mouse model of Trypanosoma vivax infection identify protective invariant subunit vaccine antigens, and demonstrate the possibility of generating effective vaccines that induce long-lasting protection against trypanosome infections.

The molecular basis of proprioceptive neuron subtype identities is not fully understood. Here the authors investigate diversity of proprioceptive neurons connected to different muscles at the molecular level, and show that acquisition of muscle-type identity precedes the emergence of receptor character and contains effectors controlling muscle connectivity.

Systematic analysis of the zebrafish synapse proteome has been lacking. Here the authors characterize the ultrastructure of zebrafish synapse and compare the proteomes of postsynaptic density in zebrafish and mice, offering a resource for future studies using zebrafish to model diseases.

The egg receptor for Izumo, a sperm cell-surface protein required for male fertility, is identified here and renamed Juno; these findings show that the Izumo–Juno interaction is conserved within mammals, and open new opportunities for the development of fertility treatments and contraceptives.

V2a excitatory interneurons in the spinal cord are important for coordinating locomotion. Here the authors describe two types of V2a neuron with differences in higher order and lower order connectivity in larval zebrafish.

DNA-dependent protein kinase (DNA-PK) plays a major role in the DNA damage response upon double-strand break formation. Here, the authors show that the DNA-PK inhibitor AZD7648, enhances the activity of radiotherapy, chemotherapy and the PARP inhibitor olaparib in multiple mouse tumour models.

Alterations of locus coeruleus signal intensity have been associated with functional changes in health and disease. Here, the authors tested a pre-registered hypothesis on a large number of subjects as part of the Cam-CAN consortium.

Epilepsies are common brain disorders and are classified based on clinical phenotyping, imaging and genetics. Here, the authors perform genome-wide association studies for 3 broad and 7 subtypes of epilepsy and identify 16 loci - 11 novel - that are further annotated by eQTL and partitioned heritability analyses.

Cognitive abilities change with age, but why some decline and some do not is not clear. Here, the authors use data from the Cam-CAN cohort to show that distributed, multi-component brain responsivity and default-mode deactivation supports and characterizes preserved cognition across the adult lifespan.

Interferon-inducible transmembrane (IFITM) protein 3 is shown to be an innate defence mechanism against viral infection in vivo; furthermore, a subset of the patients hospitalized during the H1N1 2009 pandemic carried a variant form of the IFITM3 gene.

Experiments at the Joint European Torus tokamak show improved thermal ion confinement in the presence of highly energetic ions and Alfvénic instabilities in the plasma.

Decline in sensorimotor skills with age may be due to an overreliance on the prediction of the sensory consequences of one’s actions. Here the authors show that sensorimotor attenuation increases with age, and that this is associated with structural and functional changes in frontostriatal circuits.

Executive functions are affected by ageing but it is unclear how. Kievit et al.use brain imaging and modelling approaches to show how multifactorial explanations outperform single-factor models when relating age-related differences in grey and white matter to differences in fluid intelligence and multitasking.

A novel approach is used to cultivate a substantial proportion of the human gut microbiota, representing an important step forward in characterizing the role of these bacteria in health and disease.

Mutation of a mismatch repair gene accelerated the genomic mutation rate of Salmonella Enteritidis infecting an immunocompromized individual, leading to levels of evolution that parallel those found in successful host-restricted bacterial pathogens.

Tokamak plasmas are prone to sudden collapses that terminate the nuclear fusion reactions. This perspective discusses the prediction of these so-called disruptions with artificial intelligence techniques.
