    Episode 30: June 2016

    In this episode we hear about drug production, early career researchers, honeybees, human migrations and pain.
    1. Neuroscience

    A principle of economy predicts the functional architecture of grid cells

    Xue-Xin Wei et al.
    Mathematical modeling suggests that grid cells in the rodent brain use fundamental principles of number theory to maximize the efficiency of spatial mapping, enabling animals to accurately encode their location with as few neurons as possible.

    Tuning of delta-protocadherin adhesion through combinatorial diversity

    Adam J Bisogni et al.
    Combinatorial expression patterns of δ-Pcdhs are defined within single neurons, and in vitro assays are employed to establish guiding principles used by this gene family to mediate cell adhesion.
    1. Neuroscience

    Hunger neurons drive feeding through a sustained, positive reinforcement signal

    Yiming Chen et al.
    Hunger neurons promote feeding by triggering a long-lasting potentiation of the rewarding properties of food.
    1. Biochemistry and Chemical Biology
    2. Chromosomes and Gene Expression

    Compensatory induction of MYC expression by sustained CDK9 inhibition via a BRD4-dependent mechanism

    Huasong Lu et al.
    A new potent and selective CDK9 inhibitor induces the expression of the proto-oncogene MYC via a mechanism that depends on the bromodomain protein BRD4.
    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.

    2. Neuroscience

    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.

    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.

    A cytoplasmic peptidoglycan amidase homologue controls mycobacterial cell wall synthesis

    Cara C Boutte et al.
    Cell wall biosynthesis in mycobacteria is regulated by an unusual post-translational regulatory system that contributes to antibiotic tolerance during stress.

    The Notch-mediated hyperplasia circuitry in Drosophila reveals a Src-JNK signaling axis

    Diana M Ho et al.
    A diverse group of modifier genes, including the proto-oncogene Src, cooperate with Notch specifically to control cell proliferation.
