    Active site geometry stabilization of a presenilin homolog by the lipid bilayer promotes intramembrane proteolysis

    Lukas P Feilen, Shu-Yu Chen ... Harald Steiner
    Biochemical studies in combination with computational modeling and molecular dynamics simulations reveal that the lipid bilayer promotes intramembrane proteolysis by stabilizing the enzyme-substrate complex and the protease active site.

    Neural synchronization is strongest to the spectral flux of slow music and depends on familiarity and beat salience

    Kristin Weineck, Olivia Xin Wen, Molly J Henry
    Two different analysis approaches for measuring neural synchronization to natural music revealed strongest synchronization to musical spectral flux as opposed to the more commonly used amplitude envelope.

    Kinesin-4 KIF21B limits microtubule growth to allow rapid centrosome polarization in T cells

    Peter Jan Hooikaas, Hugo GJ Damstra ... Anna Akhmanova
    Kinesin-4 KIF21B promotes rapid reorientation of the microtubule network during formation of immunological synapse in T cells by acting as a pausing and catastrophe-inducing factor that keeps microtubules short.

    Direct extraction of signal and noise correlations from two-photon calcium imaging of ensemble neuronal activity

    Anuththara Rupasinghe, Nikolas Francis ... Behtash Babadi
    An inference paradigm for extracting neuronal correlations from two-photon imaging data, without requiring intermediate spike deconvolution, provides significant performance gains over existing methods as demonstrated by theoretical analysis, simulation studies, and real-data applications.
