    Episode 20: May 2015

    In this episode we hear about echolocation, bacteriophages, babies and pain, a neural code for food abundance, and how zebrafish can make their own sunscreen.

    The structure of species discrimination signals across a primate radiation

    Sandra Winters et al.
    Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.

    A regulatory microRNA network controls endothelial cell phenotypic switch during sprouting angiogenesis

    Stefania Rosano et al.
    Coordinated microRNAs activity induced by VEGF represses cell proliferation and favors cell migration at the onset of sprouting angiogenesis in endothelial cells.

    Homeostatic plasticity fails at the intersection of autism-gene mutations and a novel class of common genetic modifiers

    Özgür Genç et al.
    Forward genetic screens define a novel genetic landscape by which diverse, unrelated autism risk genes may converge to commonly affect the robustness of synaptic transmission.

    Extensive intraspecies cryptic variation in an ancient embryonic gene regulatory network

    Yamila N Torres Cleuren et al.
    Quantitative genetic analyses reveal remarkably broad genetic variation underlies the requirement for two critical regulatory inputs into a core embryonic gene regulatory network within one animal species.
    1. Chromosomes and Gene Expression

    Transcription factor clusters regulate genes in eukaryotic cells

    Adam JM Wollman et al.
    Transcription factors form clusters independently of the presence of DNA, which regulate target genes as opposed to individual monomers, addressing a longstanding question of how transcription factors can find gene targets so quickly.
    1. Neuroscience

    Brain signatures of a multiscale process of sequence learning in humans

    Maxime Maheu et al.
    Evidence for multiple brain systems for sequence processing involving statistical inferences at multiple scales.
    1. Neuroscience

    Sparse recurrent excitatory connectivity in the microcircuit of the adult mouse and human cortex

    Stephanie C Seeman et al.
    A high-throughput pipeline for the characterization of cortical connectivity in mouse and human cortex.

    Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity

    Onur Ozan Koyluoglu et al.
    A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.
