  1. Episode 37: March 2017

    In this episode we hear about helping people with paralysis to communicate, how exposing mice to nicotine can affect their sons, scaffold-building parasites, the origins of handedness and plain-language summaries of research.

    Spatial readout of visual looming in the central brain of Drosophila

    Mai M Morimoto et al.
    In the Drosophila central brain, synaptic connectivity extracts visual-spatial information from the axons of looming sensitive LC6 neurons that terminate in a glomerulus with minimal retinotopy.

    Three rules govern thalamocortical connectivity of fast-spike inhibitory interneurons in the visual cortex

    Yulia Bereshpolova et al.
    In the visual system, three rules guide the thalamocortical connectivity of cortical fast-spike interneurons and are key to understand the potent and broadly tuned feed-forward inhibition that they generate.

    Social interactions drive efficient foraging and income equality in groups of fish

    Roy Harpaz, Elad Schneidman
    Analysis and modeling of group behavior of adult zebrafish shows that a specialized social interaction mechanism increases foraging efficiency and equality within groups, under a variety of environmental conditions.

    Neuronal octopamine signaling regulates mating-induced germline stem cell increase in female Drosophila melanogaster

    Yuto Yoshinari et al.
    Genetic analyses using the fruit fly illustrate how neuronal system couples germline stem cell increase to an external cue, which is mating, through stem cell niche signaling.

    A gradient of Wnt activity positions the neurosensory domains of the inner ear

    Magdalena Żak, Nicolas Daudet
    Manipulations of Wnt signalling in the chicken embryo reveal how it controls in a dose-dependent manner the formation of the neurosensory territories of the early developing inner ear.

    Identifying molecular features that are associated with biological function of intrinsically disordered protein regions

    Taraneh Zarin et al.
    A statistical model systematically associates functions of intrinsically disordered regions with sequence-distributed molecular features such as charge, residue composition, or repeat content.

    Genomic and healthcare dynamics of nosocomial SARS-CoV-2 transmission

    Jamie M Ellingford et al.
    Characterisation of SARS-CoV-2 genomic divergence in healthcare-associated outbreaks demonstrates that the inclusion of healthcare workers in contact networks identifies additional links in SARS-CoV-2 transmission pathways.

    A simple and effective F0 knockout method for rapid screening of behaviour and other complex phenotypes

    François Kroll et al.
    Zebrafish knockouts can be generated in a few hours directly from wild-type eggs and are suitable for studying continuous traits, including behaviour.

    Reactive oxygen species oxidize STING and suppress interferon production

    Lili Tao et al.
    Redox modification of STING represents a novel target for interferon regulation and control of herpesvirus replication.
