Severe sepsis has a high mortality rate. Here, the authors provide genomic, transcriptomic, proteomic and metabolomic data across four sepsis-causing pathogens and identify a signature of global increase in fatty acid and lipid biosynthesis as well as cholesterol acquisition.

Koenig et al. describe two Campylobacter small RNAs (FlmE and FlmR) that are co-regulated within the flagellar transcriptional cascade and together post-transcriptionally fine-tune expression of components during flagellar biogenesis.

There have been increasing reports of extensively drug-resistant (XDR) Shigella sonnei infections in recent years. In this laboratory surveillance study from France, the authors document the rise of XDR isolates from 2005 to 2021 and perform whole genome sequencing to investigate their genomic diversity and evolutionary history.

Monocytes constitutively adhere and crawl along the glomerular endothelium and are thought to contribute to glomerulonephritis. Here the authors use multiphoton microscopy to show local antigen presentation by MHCII⁺ monocytes to T cells in glomerular capillaries of mice.

Niche theory is often invoked to explain biodiversity, but it does not explain how species evolve to exploit unique niches. Using a combination of experimental and computational approaches, this study shows that resource competition can deform fitness landscapes, opening new pathways that promote ecological speciation.

Investigation of variation in three cohorts has identified multiple genetic signals associated with the pregnancy-specific liver disorder, intrahepatic cholestasis of pregnancy, giving insight into the disease which can cause preterm birth and stillbirth.

Modern 3D printers are still controlled using Geometry Code, a programming language that dates back nearly a century. In this work, the authors present a time-based synchronization method—Time Code—which decouples printhead controls from motion planning, allowing for seamless functionalization of print paths.

We quantify mitochondrial DNA copy number and heteroplasmy levels and study their association with nuclear genetic loci in population-scale biobanks.

Dominic Kwiatkowski and colleagues of the MalariaGEN and the WTCCC consortiums report a genome-wide analysis of severe malaria in The Gambia. They provide guidance for design of GWAS in African populations, and demonstrate the usefulness of multipoint imputation based on population-specific sequencing data.

A class of chimeric synthetic antibiotics that bind to lipopolysaccharide and BamA shows potent activity against multidrug-resistant Gram-negative bacteria, with the potential to address life-threatening infections.

Computational search identifies dynobactin A which is a systemically active, natural-product peptide antibiotic that kills Gram-negative bacteria.

Taxonomical complexity has muddled the classification of clinically relevant Enterobacter species. Authors carry out a genome-based study on clinical isolates to investigate colistin resistance and heteroresistance in Enterobacter.

Cortex morphology varies with age, cognitive function, and in neurological and psychiatric diseases. Here the authors report 160 genome-wide significant associations with thickness, surface area and volume of the total cortex and 34 cortical regions from a GWAS meta-analysis in 22,824 adults.

In this study, the authors report that post-vaccination neutralizing and binding antibody levels in the ENSEMBLE trial associate with Ad26.COV2.S vaccine efficacy (VE) against severe-critical COVID-19, with substantial VE even at unquantifiable neutralizing antibody titer.

Transcription is globally repressed in early stage of embryo development, but a set of genes including pri-miR-430 and zinc finger genes is known to escape the repression. Here the authors image the very first transcriptional activities in the living zebra fish embryo, demonstrating a cell cycle-coordinated polymerase II transcription compartment.

The authors performed phylogenetically controlled behavioural assays and analysed brain transcriptomes across five avian families, identifying convergent patterns of gene expression associated with aggression and nesting behaviour in obligate cavity-nesting birds.

Many bacteria release DNA and membrane vesicles through unclear mechanisms. Here, the authors show that a prophage endolysin is involved in the explosive lysis of a sub-population of cells in Pseudomonas aeruginosa, releasing cytoplasmic content and membrane fragments that rapidly form membrane vesicles.

The emergence of Gram-negative pathogens resistant to carbapenem antibiotics is a global health concern and carbapenem resistance often arises through acquisition of β-lactamase enzymes; this study identifies the natural fungal product aspergillomarasmine A as a metallo-β-lactamase inhibitor and a potential treatment to tackle carbapenem resistance.
