Here, the authors develop proteogenomic methods to defining cancer signaling in-vivo starting from core needle biopsies and with application to a HER2 breast cancer focused clinical trial.

The efficacy of carbapenem antibiotics can be compromised by metallo-β-lactamases, but a high-throughput screen followed by optimization has now enabled the discovery of indole-2-carboxylates (InCs) as potent broad-spectrum metallo-β-lactamase inhibitors. The results highlight the potential of InC–carbapenem combinations for clinical use as well as mechanism-guided approaches to combatting globally disseminated antibiotic resistant mechanisms.

In the first SARS-CoV-2 challenge study in humans, 36 young, healthy adult participants were intranasally inoculated with virus and monitored for productive infection, symptoms, virus kinetics, antibody response and safety in a controlled setting.

The BRAIN Initiative Cell Census Network has constructed a multimodal cell census and atlas of the mammalian primary motor cortex in a landmark effort towards understanding brain cell-type diversity, neural circuit organization and brain function.

Prostate cancer often does not progress to invasive disease and thus markers predicting the course of the disease progression are critical for optimal treatment choices. Here the authors show that variants at two genetic loci correlate with the aggressiveness of prostate cancer.

Contrary to the view that urbanization is a major driver of the global rise in obesity, the global increase in body-mass index is shown to be mostly due to increases in the body-mass indexes of rural populations.

Extracting information about polymer network topology from mechanical properties alone remains challenging. Here the authors develop a forensic approach to quantify network structural information by analysing their nonlinear mechanics.

Iron nitride (Fe₄N) is detected on magnetite particles within the Ryugu sample returned by Hayabusa2. It is probably the product of impacts of nitrogen-rich dust from the outer Solar System on the surface of Ryugu, indicative of a flux of N-rich dust in the inner Solar System.

The authors examined how family experiences are linked to the development of trust in adolescence and young adulthood. They show that trust increases over time but self-reported family adversity can hinder this, and trust may act as a resilience factor in maintaining positive peer relations.

Analyses of expression profiles from whole blood of 31,684 individuals identify cis-expression quantitative trait loci (eQTL) effects for 88% of genes and trans-eQTL effects for 37% of trait-associated variants.

New microgrid recordings on the human hippocampal surface reveal that oscillations travel in reversing directions. The route of travel at a given moment was related to behavior and topographic patterns of activity strength, suggesting directions may be biomarkers of hippocampal cognitive processes.

Engineered, bifunctional receptors present antigens and initiate signaling in response to binding to the cognate T cell receptor. Libraries built with SABRs can screen thousands of epitopes for the discovery of T cell target antigens.

Ancient mitochondrial DNA from sediments reveals the sequence of Denisovan, Neanderthal and faunal occupation of Denisova Cave, and evidence for the appearance of modern humans at least 45,000 years ago.

Stefan Schreiber and colleagues report the results of a genome-wide association study for sarcoidosis, a complex chronic inflammatory disorder. Variants near ANXA11 and PLAC9 are associated with elevated risk of the disease, with ANXA11 as the stronger candidate.

Approximately half of the people currently with multiple sclerosis (MS) are ≥50 years of age, yet guidelines for management of MS in older age are lacking. This Consensus statement presents the outcomes of an International Advisory Committee on Clinical Trials (IACCT) in MS workshop on ageing and MS, including recommendations for advancing research, care and awareness.

Long-read single-cell RNA sequencing is capable of detecting isoform-level gene expression and genomic alterations such as mutations and gene fusions, thereby providing cell-specific genotype-phenotype information. Here, the authors use long-read scRNA-seq on metastatic ovarian cancer samples and detect cell-type specific isoforms and gene fusions that may otherwise be misclassified in short-read data.

Advanced ecological modelling reveals how Sahul (Australia and New Guinea) was first peopled, suggesting the most probable routes and surprisingly rapid early settlement of this continent by anatomically modern humans starting 50,000 to 75,000 years ago.

The post-acute impacts of COVID-19 in children and adolescents are not well understood. In this population-based study in Geneva, the authors find evidence of COVID-19-related symptom persistence beyond 12 weeks in adolescents, and identify chronic conditions and lower socioeconomic status as risk factors.

Although digital twins first originated as models of physical systems, they are rapidly being applied to social systems, such as cities. This Perspective discusses the development and use of digital twins for urban planning.

The bacterial pathogen Helicobacter pylori is known for its ability to induce DNA double-strand breaks in the genome of its target cells. Here, we show that H. pylori-induced DNA damage and replication stress occurs in S-phase cells as a result of R-loop-mediated transcription/replication conflicts that are triggered by activation of the ALPK1/TIFA/NF-κB signaling axis.
