    Homeostatic control of cell wall hydrolysis by the WalRK two-component signaling pathway in Bacillus subtilis

    Genevieve S Dobihal, Yannick R Brunet ... David Z Rudner
    Molecular genetic analyses define the first homeostatic control pathway that maintains cell wall remodeling activity during bacterial growth.

    Extensive remodelling of the cell wall during the development of Staphylococcus aureus bacteraemia

    Edward JA Douglas, Nathanael Palk ... Ruth C Massey
    The transition of Staphylococcus aureus from commensalism to invasive disease, bacteraemia, is a complex balancing act offsetting offensive and defensive virulence strategies involving the Tca cell wall stress stimulon locus.

    Differential increase of hippocampal subfield volume after socio-affective mental training relates to reductions in diurnal cortisol

    Sofie Louise Valk, Veronika Engert ... Tania Singer
    Socio-emotional behavioral intervention links to changes in the structure and function of hippocampal subfields, in particular CA1-3, and reductions in cortisol levels in healthy adults.

    Functional and microstructural plasticity following social and interoceptive mental training

    Sofie Louise Valk, Philipp Kanske ... Tania Singer
    Training attention-mindfulness, emotion-motivational, and social cognitive skills over the course of 3 months alters brain functional and microstructural organization as a function of training content.

    Mechanism of environmentally driven conformational changes that modulate H-NS DNA-bridging activity

    Ramon A van der Valk, Jocelyne Vreede ... Remus T Dame
    The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

    Structure and dynamics of cholesterol-mediated aquaporin-0 arrays and implications for lipid rafts

    Po-Lin Chiu, Juan D Orjuela ... Thomas Walz
    Electron crystallography and molecular dynamics simulations show that a cholesterol sandwiched in between two neighboring aquaporin-0 tetramers stabilizes the association between the tetramers and thus promotes array formation.

    Infectious polymorphic toxins delivered by outer membrane exchange discriminate kin in myxobacteria

    Christopher N Vassallo, Pengbo Cao ... Daniel Wall
    Serial cell-to-cell transfer of lipoprotein toxins by outer membrane exchange provides a potent platform for kin discrimination in Myxococcus xanthus.

    Environmental pH signals the release of monosaccharides from cell wall in coral symbiotic alga

    Yuu Ishii, Hironori Ishii ... Shinichiro Maruyama
    Coral symbiotic alga is capable of degrading the own cell wall components by cellulase-related enzymes and releasing sugars as a simple and autonomous environmental response, even when the host-derived signals are not present.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor, Benjamin P Bratton ... Nina R Salama
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.
    1. Neuroscience

    Variance adaptation in navigational decision making

    Ruben Gepner, Jason Wolk ... Marc Gershow
    Fruit fly larvae adapt their decision-making process to the variability of the environment, illuminating the structure of adaptation in the underlying neural substrates.
