    Lying in a 3T MRI scanner induces neglect-like spatial attention bias

    Axel Lindner et al.
    Exposing subjects to the magnetic field of an MRI scanner stimulates the vestibular organ and thereby induces a horizontal bias of spatial orienting and exploration similar to that seen in stroke patients with spatial neglect.

    The cAMP effector PKA mediates Moody GPCR signaling in Drosophila blood–brain barrier formation and maturation

    Xiaoling Li et al.
    A polarized Moody/protein kinase A pathway plays an unrecognized central role in controlling the enormous cell growth and blood–brain barrier integrity in a highly coordinated spatiotemporal manner in brain homeostasis.

    Cortical magnification in human visual cortex parallels task performance around the visual field

    Noah C Benson et al.
    In humans, the surface area of early visual cortex across polar angle is distributed in a pattern that correlates strongly with radial asymmetries in behavioral performance on visual tasks.

    Functional development of a V3/glycan-specific broadly neutralizing antibody isolated from a case of HIV superinfection

    Mackenzie M Shipley et al.
    A bnAb derived from a case of HIV superinfection has distinct qualities from other HIV-specific bnAbs, including framework residues that contribute to neutralization breadth and a unique viral escape profile.

    Characterization of cephalic and non-cephalic sensory cell types provides insight into joint photo- and mechanoreceptor evolution

    Roger Revilla-i-Domingo et al.
    Molecular, cellular and behavioral genetic approaches in Platynereis dumerilii indicate that r-Opsins can act as ancient, light-dependent modulators of mechanosensation, and suggest that light-independent mechanosensory roles of r-Opsins evolved secondarily.

    Dopamine differentially modulates the size of projection neuron ensembles in the intact and dopamine-depleted striatum

    Marta Maltese et al.
    In addition to modulating firing rates, the neurotransmitter dopamine exerts a strong influence on the overall number of neurons in striatum that are recruited during behavior.

    Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight

    NCD Risk Factor Collaboration (NCD-RisC)
    Changes in the prevalence of underweight, total obesity, and severe obesity are largely driven by shifts in the distribution of body mass index.

    Regenerative neurogenic response from glia requires insulin-driven neuron-glia communication

    Neale J Harrison et al.
    Neuronal Ia-2 and glial Kon coordinate an injury-response insulin relay that restores glial cell populations and induces neural stem cells from glia, enabling central nervous system regeneration.

    The Hippo pathway controls myofibril assembly and muscle fiber growth by regulating sarcomeric gene expression

    Aynur Kaya-Çopur et al.
    Muscle fiber growth during development is controlled by the Hippo pathway that links the assembly state of the contractile sarcomeres with the transcriptional state of the sarcomeric genes.

    Bacterial symbiont subpopulations have different roles in a deep-sea symbiosis

    Tjorven Hinzke et al.
    Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.
