    Design of the HPV-automated visual evaluation (PAVE) study: Validating a novel cervical screening strategy

    Silvia de Sanjosé, Rebecca B Perkins ... Mark Schiffman
    The PAVE strategy aims to provide a cost-effective, high quality ‘Screen-Triage-Treat’ approach for cervical cancer screening to save many lives.

    Fitness effects of CRISPR endonucleases in Drosophila melanogaster populations

    Anna M Langmüller, Jackson Champer ... Philipp W Messer
    In Drosophila, genomic CRISPR/Cas9 expression necessary for CRISPR-based gene drives harbors fitness costs presumably caused by off-target effects, which can be minimized by using a high-fidelity version of Cas9.

    The complex relationship of exposure to new Plasmodium infections and incidence of clinical malaria in Papua New Guinea

    Natalie E Hofmann, Stephan Karl ... Ivo Mueller
    Under sustained malaria control in PNG, the incidence of distinct blood-stage infections quantifies heterogeneity in transmission, significantly predicting risk of both P. falciparum and P. vivax malaria episodes at a population and individual scale.

    Multiple introductions of multidrug-resistant typhoid associated with acute infection and asymptomatic carriage, Kenya

    Samuel Kariuki, Zoe A Dyson ... Gordon Dougan
    Carriage of MDR S. Typhi H58 sublineages that also cause acute disease provides understanding of the transmission dynamics of typhoid fever and maintenance of local pathogen populations in Kenya children.

    Hybridization alters the shape of the genotypic fitness landscape, increasing access to novel fitness peaks during adaptive radiation

    Austin H Patton, Emilie J Richards ... Christopher H Martin
    Hybridization not only generates genetic diversity, but this diversity can alter the shape of the fitness landscape, changing which genotypic combinations are favored by natural selection and which accessible genotypic paths lead to novel fitness peaks.

    Genetic variation in the social environment affects behavioral phenotypes of oxytocin receptor mutants in zebrafish

    Diogo Ribeiro, Ana Rita Nunes ... Rui F Oliveira
    Individual social behavior results from the interaction between the individuals own oxytocin receptor genotype and the oxytocin receptor genotypes of other individuals present in its social environment.

    Distinguishing mutants that resist drugs via different mechanisms by examining fitness tradeoffs

    Kara Schmidlin, Sam Apodaca ... Kerry Geiler-Samerotte
    Nearly a thousand diverse adaptive mutants converge into a handful of groups for which fitness responds the same way to environmental change.

    Lifespan extension in female mice by early, transient exposure to adult female olfactory cues

    Michael Garratt, Ilkim Erturk ... Richard A Miller
    Early-life exposure to conspecific urine and bedding extends the lifespan of female mice, indicating that social chemosensory cues can influence aging in a mammal.

    Barcoded bulk QTL mapping reveals highly polygenic and epistatic architecture of complex traits in yeast

    Alex N Nguyen Ba, Katherine R Lawrence ... Michael M Desai
    A bulk barcoded quantitative trait locus approach increases the power and resolution of genotype-phenotype mapping in yeast, revealing that the genetic architecture of 18 complex traits is highly polygenic, and is characterized by widespread epistatic interactions and pleiotropic effects.
    1. Plant Biology

    Synthetic hormone-responsive transcription factors can monitor and re-program plant development

    Arjun Khakhar, Alexander R Leydon ... Jennifer L Nemhauser
    The hormonal circuitry controlling development in plants can be studied and re-programmed with hormone activated Cas9-based repressors.
