    Genetic exchange has been experimentally demonstrated for Leishmania during sand fly development, indicating a meiotic mechanism. Here the authors show that meiosis-related genes HOP1 and HAP2-2 are essential for Leishmania hybridization in vitro and in sand flies and that their deletion in one or both parents hinders mating competence.

    It can be challenging to identify extinct organisms with morphology alone. Here, the authors use non-destructive Fourier Transform Infrared Spectroscopy to determine the molecular fingerprints of eukaryotes and prokaryotes from the 407 Ma Rhynie chert fossil assemblage of Aberdeenshire, Scotland.

    Insecticide resistance (IR) poses a major global health challenge. Here, the authors generate common IR mutations in laboratory Drosophila strains and use a CRISPR-based allelic-drive to replace an IR allele with a susceptible wild-type counterpart, providing a potent new tool for vector control.

    ‘The timing and ecological dynamics of extinction in the late Pleistocene are not well understood. Here, the authors use sediment ancient DNA from permafrost cores to reconstruct the paleoecology of the central Yukon, finding a substantial turnover in ecosystem composition between 13,500-10,000 years BP and persistence of some species past their supposed extinctions.’

    Little is known on how mitonuclear interactions influence genomic divergence among hybrid and parental lineages. A study of hybridizing wood warbler species complex finds a nuclear gene block with mitochondrial functions coevolves with mitochondrial genome, driven by climate-associated divergent selection underlying hybrid-parental population divergence.

    Many nematode worms, including Caenorhabditis elegans have XX/XO sex determination, while other species have XY. The authors use a new genome assembly of the filarial parasite Brugia malayi and published data to show that nematode sex chromosome evolution is highly plastic.

    Recent evidence has questioned the dogma of strict maternal transmission of mitochondrial DNA (mtDNA) in humans. Wei et al. saw no evidence of paternal transmission of mtDNA in 11,035 human trios, and show that nuclear-mitochondrial segments (NUMTs) can give the impression of paternal mtDNA transmission, but are actually inherited through the nuclear genome.

    H3K9me3 and H3K27me3 chromatin silencing marks are usually deposited by different SET-domain proteins. Here the authors show that the Enhancer-of-zeste-like protein Ezl1, from the unicellular eukaryote Paramecium tetraurelia, catalyzes methylation of histone H3 in vitro and in vivo with an apparent specificity toward K9 and K27, and controls the repression of transposable elements.

    MANF is a secreted ER stress-inducible protein that protects neurons, pancreatic β cells and cardiomyocytes from cell death under oxidative stress, hypoxic or ischemic conditions. Here the authors show that MANF confers cytoprotection through direct binding to sulfatide followed by cellular uptake in both C. elegans and mammalian cells.

    The extent of diversity in deep subsurface mines is not well documented. Here, Borgonie et al.report the discovery of Protozoa, Fungi, Platyhelminthes, Rotifera, Annelida and Arthropoda from 1.4 km below ground, and conclude that their population growth is limited by food rather than oxygen availability.

    Copy number variation is an important source of genetic variation in natural populations and may have a role in human disease. Here, the authors identify high-order amplification structures that form large extended chromosomes and suggest that these may occur due to accidental template switching in stress conditions.
