  1. Episode 60: September 2019

    In this episode we hear about how sex makes female bees go blind, the cost of unnecessary medical procedures, how birds can fly over the Himalayas, an eLife author's trip to space and more.

    Quantifying antibiotic impact on within-patient dynamics of extended-spectrum beta-lactamase resistance

    Rene Niehus et al.
    A data-driven within-host model reveals that different antibiotics are associated with divergent effects on antibiotic resistance carriage and abundance in hospitalised patients, with important implications for antibiotic stewardship.

    Sex-determining genes distinctly regulate courtship capability and target preference via sexually dimorphic neurons

    Kenichi Ishii et al.
    Sex-specific characteristics of the fruit fly courtship behavior are not specified by a single binary switch, but as a combination of traits that are modularly specified by separable genetic switches.

    Correcting for physical distortions in visual stimuli improves reproducibility in zebrafish neuroscience

    Timothy W Dunn, James E Fitzgerald
    Computational analyses quantitatively account for optical refraction at air-water interfaces to enable visual neuroscientists to present distortion-free stimuli to underwater animals.

    Estimating effectiveness of case-area targeted response interventions against cholera in Haiti

    Edwige Michel et al.
    Case-area targeted interventions conducted by rapid response teams appeared significantly effective to mitigate and shorten local cholera outbreaks in the Centre department of Haiti in 2015-2017.

    Deep sampling of Hawaiian Caenorhabditis elegans reveals high genetic diversity and admixture with global populations

    Tim A Crombie et al.
    Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.

    Uncovering the functional anatomy of the human insula during speech

    Oscar Woolnough et al.
    Direct insular recordings in humans reveal that contrary to several prominent models of speech production, it is not engaged in pre-articulatory planning, but in auditory and somatosensory components of speech.

    Rod nuclear architecture determines contrast transmission of the retina and behavioral sensitivity in mice

    Kaushikaram Subramanian et al.
    Establishing retinal contrast transmission as a novel determinant of mammalian fitness, this research adds functional significance to a prominent exception of nuclear organization, previously described in nocturnal rod photoreceptor cells.

    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite et al.
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

    Signal categorization by foraging animals depends on ecological diversity

    David William Kikuchi et al.
    In richer, more even communities, foragers form broad categories among their food resources that can select for convergence among signals, including mimetic resemblances.
