    Physical limits of flow sensing in the left-right organizer

    Rita R Ferreira et al.
    Large-scale in vivo imaging of the zebrafish left-right organizer (Kupffer's vesicle) combined with fluid dynamics calculations allows to quantitatively test the possible flow detection mechanisms and supports the flow transport of chemical signals as the mechanism of side determination.

    Cell cycle entry triggers a switch between two modes of Cdc42 activation during yeast polarization

    Kristen Witte et al.
    Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.

    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.

    Mice deficient of Myc super-enhancer region reveal differential control mechanism between normal and pathological growth

    Kashyap Dave et al.
    A tumor-specific regulatory region has been identified upstream of the Myc oncogene.

    Embryonic transcription factor expression in mice predicts medial amygdala neuronal identity and sex-specific responses to innate behavioral cues

    Julieta E Lischinsky et al.
    Studying the development of the medial amygdala in the mouse reveals how the brain may potentially process sex differences in innate behaviors such as mating.

    Decoupling global biases and local interactions between cell biological variables

    Assaf Zaritsky et al.
    DeBias is a generic method to decompose and quantify the confounding, global factors and direct interactions of pairwise interacting variables.

    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.

    Codon optimization underpins generalist parasitism in fungi

    Thomas Badet et al.
    Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

    CCR5 is a suppressor for cortical plasticity and hippocampal learning and memory

    Miou Zhou et al.
    Repression of the G protein-coupled chemokine receptor CCR5 enhances MAPK/CREB signaling, long-term potentiation, somatosensory cortical plasticity, and learning and memory, while CCR5 over-activation by viral proteins may contribute to HIV-associated cognitive deficits.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho et al.
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.
