    Computational prediction of CTCF/cohesin-based intra-TAD loops that insulate chromatin contacts and gene expression in mouse liver

    Bryan J Matthews, David J Waxman
    Certain types of 3D chromatin loops are easy to predict from existing or easily obtainable 2D information, which benefits gene expression studies in tissues/cells/organisms without extensive pre-existing 3D information.

    Dcp2 C-terminal cis-binding elements control selective targeting of the decapping enzyme by forming distinct decapping complexes

    Feng He, Chan Wu, Allan Jacobson
    Dcp2 C-terminal domain cis-regulatory elements collaborating with specific activators control decapping enzyme targeting and activation by orchestrating sequential assembly of distinct decapping complexes.

    Removal of inhibition uncovers latent movement potential during preparation

    Uday K Jagadisan, Neeraj J Gandhi
    Non-invasive disinhibition of the oculomotor system shows that ongoing preparatory activity in the superior colliculus has movement-generating potential and need not rise to threshold in order to produce a saccade.

    Evidence for a common evolutionary rate in metazoan transcriptional networks

    Anne-Ruxandra Carvunis, Tina Wang ... Trey Ideker
    Transcriptional regulation evolves at indistinguishable rates in mammals, birds and insect lineages despite large differences in underlying rates of sequence evolution.

    Whole brain correlates of individual differences in skin conductance responses during discriminative fear conditioning to social cues

    Kevin Vinberg, Jörgen Rosén ... Fredrik Ahs
    A whole brain analysis using human neuroimaging data shows neural correlates of individual differences in conditioned fear.

    Evolution of cell size control is canalized towards adders or sizers by cell cycle structure and selective pressures

    Felix Proulx-Giraldeau, Jan M Skotheim, Paul François
    An evolutionary algorithm is used to build gene networks implementing cell size control, and suggests multiple ways for evolution to first build sizers and turn them into adders depending on evolutionary constraints.

    Host-pathogen genetic interactions underlie tuberculosis susceptibility in genetically diverse mice

    Clare M Smith, Richard E Baker ... Christopher M Sassetti
    A novel dual genome approach that combines genetically diverse mice and a library of bacterial mutants to define the genome-wide host pathogen interactions that drive distinct outcomes to tuberculosis.

    Transgenerational dynamics of rDNA copy number in Drosophila male germline stem cells

    Kevin L Lu, Jonathan O Nelson ... Yukiko M Yamashita
    rDNA copy number is shown to dynamically change during aging and through generations, and is actively maintained in male germline of Drosophila.

    Muscarinic receptors mediate motivation via preparatory neural activity in humans

    John P Grogan, Matthias Raemaekers ... Sanjay G Manohar
    Muscarinic antagonism is causally involved in motivation and incentivisation in healthy human participants, partially mediated via preparatory neural signatures, with implications for cholinergic treatment of Parkinson's disease.

    Divisive suppression explains high-precision firing and contrast adaptation in retinal ganglion cells

    Yuwei Cui, Yanbin V Wang ... Daniel A Butts
    The convergence of two visual pathways at the level of retinal bipolar cells accounts for key features of ganglion cell responses.
