    Cortical bone maturation in mice requires SOCS3 suppression of gp130/STAT3 signalling in osteocytes

    Emma C Walker et al.
    Targeted SOCS3 null mice reveal that maturation of cortical bone comprises both pore closure and accumulation of high density bone, requiring local suppression of gp130-STAT3 in osteocytes and subsequent osteoclastogenesis.

    Distinct roles for innexin gap junctions and hemichannels in mechanosensation

    Denise S Walker, William R Schafer
    The innexin protein UNC-7, a homologue of vertebrate pannexins, plays a specific, gap junction-independent role in C. elegans mechanosensation.

    Independent evolution of ancestral and novel defenses in a genus of toxic plants (Erysimum, Brassicaceae)

    Tobias Züst et al.
    A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

    Layered roles of fruitless isoforms in specification and function of male aggression-promoting neurons in Drosophila

    Margot Wohl et al.
    Male-type aggressive and courtship behaviors of the fruit flies are differentially specified by two sex-determining genes, providing a substrate for the evolution to sculpt these two behaviors independently.

    Kainate receptors regulate development of glutamatergic synaptic circuitry in the rodent amygdala

    Maria Ryazantseva et al.
    Glutamatergic projections from basolateral to central amygdala, implicated in neuropsychiatric disorders, develop rapidly during early postnatal period and their development is modulated via endogenously active kainate receptors.

    A processive rotary mechanism couples substrate unfolding and proteolysis in the ClpXP degradation machinery

    Zev A Ripstein et al.
    Understanding of bacterial protein degradation is illuminated by cryo-EM structures of the substrate-bound ClpXP complex from Neisseria meningitidis at 2.3 to 3.3 Å resolution.

    Stochastic yield catastrophes and robustness in self-assembly

    Florian M Gartner et al.
    Fluctuations in the availability of particles for binding can completely jeopardize yield in heterogeneous self-assembly.

    Translational initiation in E. coli occurs at the correct sites genome-wide in the absence of mRNA-rRNA base-pairing

    Kazuki Saito et al.
    E. coli ribosomes incapable of base-pairing with the Shine-Dalgarno sequence are still selective for annotated start sites, indicating these sites are hard-wired for initiation by other mRNA features.

    Noninvasive quantification of axon radii using diffusion MRI

    Jelle Veraart et al.
    Cell-specific architectural properties such as the axon diameter of the white matter of the human brain can be quantified accurately and non-invasively using diffusion magnetic resonance imaging.

    Experience shapes activity dynamics and stimulus coding of VIP inhibitory cells

    Marina Garrett et al.
    VIP inhibitory neurons are active in response to novel images but are suppressed by familiar stimuli and show ramping activity when expected stimuli are omitted.
