    Obligate coupling of CFTR pore opening to tight nucleotide-binding domain dimerization

    Csaba Mihályi et al.
    Coupling of CFTR pore opening to nucleotide binding domain dimerization does not depend on ATP binding, but is an inherent property of the channel protein and likely other ABC transporters.

    Community-level cohesion without cooperation

    Mikhail Tikhonov
    A model of purely competitive ecological dynamics is shown to be equivalent to adaptive evolution of a single individual, suggesting a new way to formalize the "superorganism" metaphor.

    Centering and symmetry breaking in confined contracting actomyosin networks

    Niv Ierushalmi et al.
    Novel mechanisms for cellular centering and symmetry breaking involving persistent contractile actomyosin flows and their hydrodynamic interactions with the fluid cytosol are presented and studied using a minimal, reconstituted system.

    Fish-hunting cone snail venoms are a rich source of minimized ligands of the vertebrate insulin receptor

    Peter Ahorukomeye et al.
    The unique modus operandi of cone snail venom insulins provides new insight into insulin receptor activation and informs on the design of insulin analogs for the treatment of diabetes.

    Conformation of the nuclear pore in living cells is modulated by transport state

    Joan Pulupa et al.
    Polarized fluorescence microscopy of individual nuclear pores in vivo reveals conformational changes in select domains of proteins of the inner ring.

    Comment on "Magnetosensitive neurons mediate geomagnetic orientation in Caenorhabditis elegans"

    Lukas Landler et al.
    Employing blinded controlled methodology we find no evidence for a magnetic sense in the nematode worm Caenorhabditis elegans.

    Functional heterogeneity within the rodent lateral orbitofrontal cortex dissociates outcome devaluation and reversal learning deficits

    Marios C Panayi, Simon Killcross
    The rodent orbitofrontal cortex makes functionally distinct contributions to flexible behavioural control, even within a single putative orbitofrontal subregion, which has important implications for establishing homology between rodent and primate orbitofrontal cortex.

    Efficacy of β-lactam/β-lactamase inhibitor combination is linked to WhiB4-mediated changes in redox physiology of Mycobacterium tuberculosis

    Saurabh Mishra et al.
    Intrinsic tolerance of Mycobacterium tuberculosis toward the world's most successful antibacterials, β-lactams, is dependent on cytoplasmic redox potential and an intracellular redox-sensor WhiB4.

    Serial, parallel and hierarchical decision making in primates

    Ariel Zylberberg et al.
    A comparison between hierarchical and flat models of decision-making refutes flat models because they lack flexibility and are not supported by behavioral and neural data.

    DYT1 dystonia increases risk taking in humans

    David Arkadir et al.
    Patients with DYT1 dystonia show aberrant risk-aversion in a simple decision-making task, in accordance with predictions of a reinforcement learning model of corticostriatal trial-and-error learning.
