    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Asymmetric division triggers cell-specific gene expression through coupled capture and stabilization of a phosphatase

    Niels Bradshaw, Richard Losick
    Asymmetric cell division is linked to cell-specific transcription by handoff of a key developmental regulator from the cytokinetic machinery to the adjacent cell pole where it oligomerizes to become stabilized and activated.

    Extensive cargo identification reveals distinct biological roles of the 12 importin pathways

    Makoto Kimura et al.
    Transport-based high-throughput identification of cargo proteins specific to all 12 human importin-β family nuclear import receptors revealed biological processes that the cargo cohorts of each receptor are involved in.

    Comment on ‘Orthogonal lipid sensors identify transbilayer asymmetry of plasma membrane cholesterol’

    Kevin C Courtney et al.
    We challenge a recent report that most of the cholesterol in the plasma membrane of mammalian cells is in the exofacial leaflet.

    Erythropoietin signaling regulates heme biosynthesis

    Jacky Chung et al.
    EPO/JAK2/PKA signaling cascade via AKAP10 relocalization to the outer mitochondrial membrane results in the phosphorylation of the terminal heme synthesis enzyme ferrochelatase, which contributes to heme production in red cells.

    Coupling between the DEAD-box RNA helicases Ded1p and eIF4A

    Zhaofeng Gao et al.
    Ded1p and eIF4A, two RNA helicases that function in eukaryotic translation initiation, interact physically with each other and with the scaffolding protein eIF4G.

    Calcium handling precedes cardiac differentiation to initiate the first heartbeat

    Richard CV Tyser et al.
    High-resolution live imaging reveals how and when the mouse heart first starts to beat during development and how the onset of beating impacts on heart muscle cell maturation and heart formation.

    A hierarchy of timescales explains distinct effects of local inhibition of primary visual cortex and frontal eye fields

    Luca Cocchi et al.
    The selective effect of local inhibition on diffuse patterns of brain connectivity can be accounted for by an intrinsic hierarchical ordering of cortical timescales.

    Physical limits to magnetogenetics

    Markus Meister
    Recent reports on the ability of biological molecules to sense magnetic fields are found to be inconsistent with basic physical principles.

    Harbouring public good mutants within a pathogen population can increase both fitness and virulence

    Richard J Lindsay et al.
    Cooperation theory and a novel synthetic infection system provides a mechanistic understanding of why a seemingly successful disease management strategy can have devastating consequences for infected hosts.
