    Three-color single molecule imaging shows WASP detachment from Arp2/3 complex triggers actin filament branch formation

    Benjamin A Smith et al.
    New insights into the mechanism responsible for the nucleation of branches on networks of actin filaments shed light on a process that is essential for eukaryotic cell motility and endocytosis.

    Causal evidence for lateral prefrontal cortex dynamics supporting cognitive control

    Derek Evan Nee, Mark D'Esposito
    Non-invasive brain stimulation tests and refines a model of lateral prefrontal cortex neural dynamics supporting cognitive control.

    Gene-specific mechanisms direct glucocorticoid-receptor-driven repression of inflammatory response genes in macrophages

    Maria A Sacta et al.
    A comprehensive analysis of the glucocorticoid-sensitive pro-inflammatory genes in macrophages reveals fundamental differences between the temporal events and components of transcriptional machinery that the glucocorticoid receptor targets to repress their transcription.

    Position-dependent plasticity of distinct progenitor types in the primitive streak

    Filip J Wymeersch et al.
    Neuromesodermal and lateral/ventral mesoderm progenitors represent distinct committed states, governed by separate regulatory logics.

    Deployment of a retinal determination gene network drives directed cell migration in the sea urchin embryo

    Megan L Martik, David R McClay
    The gene regulatory network controlling directed cell migration in a sea urchin is strikingly similar to a sub-circuit for eye development in Drosophila, suggesting that ancient systems-level controls may be adapted for diverse functions in different animals.

    Integrated systems analysis reveals conserved gene networks underlying response to spinal cord injury

    Jordan W Squair et al.
    Integrating decades of small-scale experiments with human gene expression data provides a systems-level view of the coordinated molecular processes triggered by spinal cord injury, and their relationship to recovery.

    Replication Study: Intestinal inflammation targets cancer-inducing activity of the microbiota

    Kathryn Eaton et al.
    Editors' Summary: This Replication Study has reproduced some parts of the original paper but it also contains results that are not consistent with other parts of the original paper.

    Structure and reconstitution of yeast Mpp6-nuclear exosome complexes reveals that Mpp6 stimulates RNA decay and recruits the Mtr4 helicase

    Elizabeth V Wasmuth et al.
    The nuclear exosome cofactors Mpp6 and Rrp47 can stimulate exoribonuclease activities of the nuclear RNA exosome and recruit the Mtr4 helicase to promote helicase dependent RNA decay.

    A simple biophysical model emulates budding yeast chromosome condensation

    Tammy MK Cheng et al.
    A computational model of a yeast chromosome, based on first principles, recapitulates in vivo chromosome behavior, and thus provides unprecedented insight into what the inside of a chromosome is likely to look like.

    Massive endocytosis triggered by surface membrane palmitoylation under mitochondrial control in BHK fibroblasts

    Donald W Hilgemann et al.
    Mitochondria can trigger massive endocytosis by releasing coenzyme A into the cytoplasm and thereby promoting the addition of fatty acids to surface membrane proteins.
