    Defining the location of promoter-associated R-loops at near-nucleotide resolution using bisDRIP-seq

    Jason G Dumelie, Samie R Jaffrey
    Genome-wide profiling of R-loops at near single-nucleotide resolution reveals distinct R-loop boundaries depending on the presence and location of the first exon-intron junction.

    Reproduction: Parasites opt for the best of both worlds

    Ellen Decaestecker, Lore Bulteel
    The fungal parasite Podosphaera plantaginis employs both sexual and asexual reproduction to increase its chances of infecting the plant Plantago lanceolata.

    Variable opportunities for outcrossing result in hotspots of novel genetic variation in a pathogen metapopulation

    Anna-Liisa Laine et al.
    In natural pathogen populations opportunities for sexual outcrossing vary, leading to spatial variation in genetic diversity and between-season survival.

    Asexual reproduction reduces transposable element load in experimental yeast populations

    Jens Bast et al.
    Sexual reproduction is responsible for the evolutionary success of selfish transposable elements.

    Using the Volta phase plate with defocus for cryo-EM single particle analysis

    Radostin Danev et al.
    Building on previous work in cryo-electron microscopy (Entchev et al, 2015), it shown that a combination of the Volta phase plate and a small amount of defocus can simplify the experimental set-up, increase the data acquisition rate and improve resolution.

    A simple method for generating high-resolution maps of genome-wide protein binding

    Peter J Skene, Steven Henikoff
    Building on previous work (Skene et al., 2014), we show that a new ChIP-seq protocol provides superior resolution and ease of use at low sequence depth of coverage for generating genome-wide maps of protein binding.

    Free-living human cells reconfigure their chromosomes in the evolution back to uni-cellularity

    Jin Xu et al.
    Human cell lines regress to become ‘de-sexualized’ by reconfiguring to a 2:3 X/A ratio of high fitness, thus shedding light on the evolution of mammalian sex chromosomes.

    Integration of human pancreatic islet genomic data refines regulatory mechanisms at Type 2 Diabetes susceptibility loci

    Matthias Thurner et al.
    Human pancreatic islet high-resolution chromatin state maps generated from DNA methylation, open chromatin and ChIP-seq mark data facilitate the characterisation of regulatory mechanisms at type 2 diabetes genome-wide association study loci.
