  1. Episode 45: February 2018

    In this episode, we hear about disease control in insects, placental development, post-traumatic stress disorder, the mission to create a human cell atlas and how crickets amplify their song.

    Two-photon calcium imaging of the medial prefrontal cortex and hippocampus without cortical invasion

    Masashi Kondo et al.
    Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.

    The Glide/Gcm fate determinant controls initiation of collective cell migration by regulating Frazzled

    Tripti Gupta et al.
    The role of the Frazzled chemoattractant receptor is to triggers migration initiation as part of the glial developmental program induced by the Glide/Gcm transcription factor.
    1. Neuroscience

    Dysregulated Dscam levels act through Abelson tyrosine kinase to enlarge presynaptic arbors

    Gabriella R Sterne et al.
    Targeting Abelson kinase can be beneficial for treating disorders characterized by dysregulated Down Syndrome Cell Adhesion Molecule signaling.

    Ovulation in Drosophila is controlled by secretory cells of the female reproductive tract

    Jianjun Sun, Allan C Spradling
    Secretory cells in the fruit fly reproductive tract produce secretions that control ovulation through a conserved mechanism that could provide insights into ovarian cancer.

    Reactive oxygen species-dependent Toll/NF-κB activation in the Drosophila hematopoietic niche confers resistance to wasp parasitism

    Isabelle Louradour et al.
    In the Drosophila hematopoietic microenvironment, a regulatory network involving Toll/NF-B, EGFR signaling and reactive oxygen species controls blood cell production in response to immune stress.

    TissueMiner: A multiscale analysis toolkit to quantify how cellular processes create tissue dynamics

    Raphaël Etournay et al.
    A computational framework called TissueMiner, complete with tutorials, will allow a wide range of users to perform quantitative multiscale analysis of tissue morphogenesis.

    Range-dependent flexibility in the acoustic field of view of echolocating porpoises (Phocoena phocoena)

    Danuta M Wisniewska et al.
    Harbor porpoises dynamically control biosonar field of view as they track and capture prey, focusing the beam through deformations to the melon.
    1. Neuroscience

    Entorhinal cortex receptive fields are modulated by spatial attention, even without movement

    Niklas Wilming et al.
    Moving covert attention can activate spatial representations in the Entorhinal cortex.

    Hypoxia-induced metabolic stress in retinal pigment epithelial cells is sufficient to induce photoreceptor degeneration

    Toshihide Kurihara et al.
    Mouse models in which hypoxia can be genetically triggered in retinal pigmented epithelial cells show that hypoxia-induced metabolic stress alone can lead to photoreceptor atrophy/dysfunction.
