    How scent and nectar influence floral antagonists and mutualists

    Danny Kessler et al.
    Floral scent and nectar are highly variable in natural populations and both traits can influence outcrossing rates differently for different pollinators and increase future herbivory.

    Cryo electron tomography with volta phase plate reveals novel structural foundations of the 96-nm axonemal repeat in the pathogen Trypanosoma brucei

    Simon Imhof et al.
    Cryo electron tomography provides the first high-resolution 3D axoneme structure from any pathogenic organism, revealing novel structures that support the unique motility of these pathogens through host tissues.

    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.

    Formation of polarity convergences underlying shoot outgrowths

    Katie Abley et al.
    Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.

    A principle of economy predicts the functional architecture of grid cells

    Xue-Xin Wei et al.
    Mathematical modeling suggests that grid cells in the rodent brain use fundamental principles of number theory to maximize the efficiency of spatial mapping, enabling animals to accurately encode their location with as few neurons as possible.

    Motor cortex signals for each arm are mixed across hemispheres and neurons yet partitioned within the population response

    Katherine Cora Ames, Mark M Churchland
    Neurons in motor cortex contain information about each arm, but these signals are separated into different dimensions, allowing separate control of each arm.

    An Eya1-Notch axis specifies bipotential epibranchial differentiation in mammalian craniofacial morphogenesis

    Haoran Zhang et al.
    Dephosphorylation of Notch1 intracellular domain by Eya1 leads to enhanced Notch signalling activity in the non-neuronal epibranchial placodal cells, revealing an essential regulation for the formation of proximal pharyngeal arches during mouse craniofacial development.

    Anatomy of nerve fiber bundles at micrometer-resolution in the vervet monkey visual system

    Hiromasa Takemura et al.
    Polarized light imaging demonstrates detailed organization of projection, callosal, longitudinal association and short association fibers in the primate visual system at micrometer-resolution.

    Replay as wavefronts and theta sequences as bump oscillations in a grid cell attractor network

    Louis Kang, Michael R DeWeese
    An experimentally supported model of grid cells naturally enables them to participate in firing sequences that encode rapid trajectories in space.
