    Bacterial infections can influence disease outcome in influenza infection; however, the mechanisms mediating these complex interactions remain unclear. Wang et al. reveal how infection with a component of the airway microbiota enhances survival during influenza infection via induction of anti-inflammatory macrophages.

    RamR is an important multidrug-resistance factor, however, its structure and the molecules to which it responds are hitherto unknown. Here, the authors report the crystal structures of RamR complexed with multiple drugs, revealing significant flexibility in its substrate-recognition region.

    Debates on the formation of banded iron formations (BIFs) in ancient iron-rich oceans are dominated by contradictions between biological and non-biological iron cycling. This study provides environmental evidence that directly implicates photosynthetic iron-oxidizing microorganisms in vast-scale BIF deposition.

    A role of toxin–antitoxin systems in global regulation of bacterial gene expression has been proposed. Bukowski et al. now demonstrate that a novel toxin–antitoxin system from S. aureusencodes an endoribonuclease that regulates virulence gene expression by targeting translation.

    The spatial and temporal organization of bacterial chromosomes is important for many cellular functions. Using high-precision measurements of fluorescently labelled chromosomal loci, Javer et al.demonstrate variation in the dynamics of different chromosomal sites, which may either be due to differential organization of the chromosome or spatial variation in molecular noise.

    Deep subsurface formations are potential sites for carbon capture and storage but how subsurface microbial communities may respond to this is not clear. Here, Mayumi et al. construct microcosms and show that increasing CO2partial pressure via carbon capture and storage more than doubles the rate of methanogenesis.

    Erm methyltransferases confer antimicrobial drug resistance and their expression is induced by macrolides. Gupta et al.show that Erm-catalysed modification of rRNA affects synthesis of some proteins and reduces cell fitness, explaining why expression of Erm is deleterious in the absence of antibiotics.

    Influenza A viruses spread through contact, large and small respiratory droplets (aerosols), but the relative importance of these modes of transmission is unclear. Cowling et al. model data from community trials of face masks and hand hygiene and find that aerosol transmission accounts for half of influenza occurrences.

    Transmission-blocking interventions aim to interrupt progression of Plasmodium parasites from the vertebrate host to the mosquito. Blagborough et al. demonstrate that only partially reducing transmission can be sufficient to eliminate experimental Plasmodiuminfection in successive mosquito and mice populations when biting rates are low.

    With paleovirology it is possible to identify ancient endogenous viral elements within eukaryotic genomes. Here Suh and colleagues report a genomic record of hepatitis endogenizations through bird’s evolution; they find a complete hepatitis genome sequence, the first discovery of a Mesozoic paleovirus genome.

    The identification of hosts of blood-sucking insects is important for studying ecological factors that affect pathogen distribution. Önder et al. report a proteomics-based methodology for the analysis of blood remnants in ticks that identifies the host species from which the tick has fed up to 6 months earlier.

    The coffee ring effect is commonly observed in drying droplets containing suspended matter leading to a deposition at the droplet edge. Sempels et al. show that self-generated biosurfactants in living bacterial systems reverse the coffee ring effect and result in a homogeneous deposition.

    Cyanobacterial symbionts of marine diatoms can localize intracellularly or externally to their host partners. Here Hilton et al. describe the genomes of two diazotroph cyanobacterial symbionts of diatoms and show that the location of the symbiont affects expression of nitrogen assimilation genes.

    Detecting and phenotyping Mycobacterium tuberculosis, especially in resource-limited settings, is important for global tuberculosis control. Here Liong et al. report a point-of-care diagnostic platform based on magnetic barcoding and nuclear magnetic resonance for the detection of mycobacterial nucleic acids.

    The number of human infections caused by the primate malaria parasite P. knowlesi is increasing. Lim et al. demonstrate that host specificity is due to the preference of the parasite for young blood cells, and that the parasite can adapt to proliferate in human blood containing a range of differently aged cells.

    The hepatitis C virus RNA genome is translated via an internal ribosome entry site. Pérard et al. present an atomic model of this site, and using molecular dynamics simulations, identify conformational flexibility that may underlie its function during translation initiation.

    Bacterial type III secretion systems (T3SS) improve the delivery of vaccine antigens and antigen-specific immune responses but require the use of live vaccines. Carleton et al. report the assembly of a functional T3SS in replication-incompetent bacterial minicells that can deliver vaccine antigens in vitro and in vivo.

    Shigella triggers an increase in intracellular calcium during invasion of host cells. Here the authors show that increased actin polymerization at the invasion site slows the diffusion of signalling mediators, thus sustaining localized calcium influx at invasion sites.

    The factors that modulate growth rate of the human malaria parasite Plasmodium falciparum remain poorly understood. Here Scherf and collaborators demonstrate that the Plasmodiumsirtuin PfSir2a regulates the transcription of ribosomal DNA, thereby modulating parasite proliferation rate and virulence.

    The recognition of viruses by synthetic materials is historically difficult. Here, a templating procedure using silica nanoparticles coated with organosilanes is used to form virus-imprinted particles, possessing both shape and chemical imprints, capable of virus recognition at picomolar concentrations.

    Bacterial cell wall peptidoglycan is essential for viability and shape determination. Using high-resolution microscopy, Foster and colleagues elucidate the peptidoglycan architecture and insertion pattern in Escherichia coliand other Gram-negative bacteria, and propose a new model for cell wall elongation.

    The bacterial tetracycline resistance protein Tet(O) binds to the ribosome, preventing tetracycline from inhibiting translation. Using cryo-electron microscopic reconstruction, the authors present an atomic model of Tet(O) bound to the 70S ribosome, and reveal how Tet(O) promotes antibiotic resistance.

    The bullet shape of Rhabdoviruses is thought to depend on their matrix protein, which stabilizes the nucleocapsid coil. Desfosses and colleagues show that the nucleoprotein of the vesicular stomatitis virus can fold the genome into a bullet-shaped skeleton in the absence of other viral components.

    Bacterial CRISPR–Cas systems provide adaptive immunity against phage by transcribing interfering RNA from phage DNA inserted into the bacterial genome. Using deep-sequencing, the authors detect a bias in the phage genome locations sampled, suggestive of selection.

    In microbial biogeography, little is known about processes involved in soil bacterial diversity turnover. By conducting a wide-scale investigation, this study shows that dispersal limitation and environmental selection of bacteria are not mutually exclusive, highlighting the importance of landscape diversity.

    Microbes living in human skin are known to influence the immune system; however, the deeper layers in which immune cells reside were thought to be largely impervious to bacteria. Nakatsuji et al.show that the skin microbiome extends into the dermis, enabling contact with cells below the basement membrane.
