    A population modification gene drive targeting both Saglin and Lipophorin impairs Plasmodium transmission in Anopheles mosquitoes

    Emily I Green, Etienne Jaouen ... Eric Marois
    Strong reduction in malaria transmission by genetically modified mosquitoes is achieved in the laboratory using a dual gene drive that simultaneously propagates an antiparasitic factor and a parasite-detrimental mosquito mutation.

    Sweepstakes reproductive success via pervasive and recurrent selective sweeps

    Einar Árnason, Jere Koskela ... Bjarki Eldon
    Selective sweepstakes from pervasive positive selection, rather than demographic changes or random sweepstakes reproduction, is the primary determinant of reproductive skew and genetic diversity in the highly prolific Atlantic cod.

    A mitochondrial DNA hypomorph of cytochrome oxidase specifically impairs male fertility in Drosophila melanogaster

    Maulik R Patel, Ganesh K Miriyala ... Harmit S Malik
    A 'male-harming' mtDNA mutation has been identified in Drosophila and impairs male fertility without impairing other male or female functions.

    ahctf1 and kras mutations combine to amplify oncogenic stress and restrict liver overgrowth in a zebrafish model of hepatocellular carcinoma

    Kimberly J Morgan, Karen Doggett ... Joan K Heath
    ELYS, a multifunctional protein with critical roles in the cell cycle, is essential for the vigorous proliferation and survival of difficult-to-treat cancers carrying mutations in the KRAS oncogene, making it a compelling target for novel drug treatments.

    A conserved filamentous assembly underlies the structure of the meiotic chromosome axis

    Alan MV West, Scott C Rosenberg ... Kevin D Corbett
    Meiotic chromosome axis 'core' proteins from fungi, plants, and mammals form a conserved filament architecture, and use a common mechanism to recruit HORMAD proteins for meiotic recombination control.

    Gendered hiring and attrition on the path to parity for academic faculty

    Nicholas LaBerge, Kenneth Hunter Wapman ... Daniel B Larremore
    Achieving gender parity among U.S. tenured and tenure-track faculty will require changes to hiring, which has substantially greater impacts on faculty gender representation than gendered differences in attrition rates.

    The population genetics of collateral resistance and sensitivity

    Sarah M Ardell, Sergey Kryazhimskiy
    A theoretical model that considers the diversity of collateral effects among drug resistance mutations provides insights into the development of robust sequential antibiotic treatments.
