    Autocatalytic microtubule nucleation determines the size and mass of Xenopus laevis egg extract spindles

    Franziska Decker et al.
    Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.

    Sweet neurons inhibit texture discrimination by signaling TMC-expressing mechanosensitive neurons in Drosophila

    Shun-Fan Wu et al.
    Drosophila use distinct sensory mechanisms to detect and integrate the same tactile and taste information in two decision-making tasks that serve two different purposes.

    Diversification of heart progenitor cells by EGF signaling and differential modulation of ETS protein activity

    Benjamin Schwarz et al.
    A novel regulatory model for the diversification of cardiac cell subpopulations in Drosophila is established by linking epidermal growth factor signaling with differential activities of key transcription factors.

    Egr-5 is a post-mitotic regulator of planarian epidermal differentiation

    Kimberly C Tu et al.
    The dynamic homeostasis of the planarian epidermis serves as an experimental paradigm to study stem cell dynamics and post-mitotic specification of diverse functional cell fates.

    Physical basis of large microtubule aster growth

    Keisuke Ishihara et al.
    Autocatalytic growth of a microtubule polymer network allows extremely large egg cells to self-organize and divide rapidly.

    Control of PNG kinase, a key regulator of mRNA translation, is coupled to meiosis completion at egg activation

    Masatoshi Hara et al.
    The kinase that controls maternal mRNA translation is regulated by phosphorylation of its activating subunit to restrict kinase activity to the developmental window between meiosis completion and early embryogenesis.

    MutSα maintains the mismatch repair capability by inhibiting PCNA unloading

    Yoshitaka Kawasoe et al.
    Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.

    Gene-free methodology for cell fate dynamics during development

    Francis Corson, Eric D Siggia
    Mathematical methods based on geometry that directly embody the developmental concepts of competency, commitment, and determination provide succinct descriptions of morphogenesis and allow quantitative predictions from fits to sparse genetic data in Caenorhabditis elegans.

    Optical detection of three modes of endocytosis at hippocampal synapses

    Natali L Chanaday, Ege T Kavalali
    Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.

    Single synapse evaluation of the postsynaptic NMDA receptors targeted by evoked and spontaneous neurotransmission

    Austin L Reese, Ege T Kavalali
    In a population of mammalian central synapses, spontaneous and evoked neurotransmitter release processes are independently distributed; yet, postsynaptic receptors within a single synapse preferentially receive neurotransmitter from only one mode of release.
