    Dynamic representation of partially occluded objects in primate prefrontal and visual cortex

    Amber M Fyall et al.
    Complementary neural codes in frontal and visual cortex support a role for feedback signals in the representation and recognition of partially occluded objects.

    The stress-responsive kinases MAPKAPK2/MAPKAPK3 activate starvation-induced autophagy through Beclin 1 phosphorylation

    Yongjie Wei et al.
    Nutrient starvation activates autophagy by a novel signaling mechanism that is blocked by one of the major autophagy inhibitors.

    Memory CD4 T cell subsets are kinetically heterogeneous and replenished from naive T cells at high levels

    Graeme Gossel et al.
    The maintenance of memory CD4 T cells in mice relies on a continual and strikingly high level of replenishment from naive precursors, and older memory T cells may resist the influx of newer ones.

    Artemisinin exposure at the ring or trophozoite stage impacts Plasmodium falciparum sexual conversion differently

    Harvie P Portugaliza et al.

    Coupling chemosensory array formation and localization

    Alejandra Alvarado et al.
    Formation and cell pole-localization of chemotactic signaling-arrays is a coupled process mediated by ParP, which drives localized array-assembly and regulates the localization-dynamics of its network constituents.

    Multiple sources of slow activity fluctuations in a bacterial chemosensory network

    Remy Colin et al.
    Single-cell FRET measurements reveal large temporal activity fluctuations within this signaling pathway in Escherichia coli, caused by stochasticity of receptor methylation combined with allosteric interactions and slow rearrangements within receptor clusters.

    Robust and accurate prediction of residue–residue interactions across protein interfaces using evolutionary information

    Sergey Ovchinnikov et al.
    Co-evolving residue pairs in the different components of a protein complex almost always make contact across the protein–protein interface, thus providing powerful restraints for the modeling of protein complexes.

    Structure of Escherichia coli respiratory complex I reconstituted into lipid nanodiscs reveals an uncoupled conformation

    Piotr Kolata, Rouslan G Efremov
    The dynamic structure of respiratory complex I from mesophilic bacterium is revealed and demonstrates existence of uncoupled conformations in the bacterial complex.
