    The transpeptidase PBP2 governs initial localization and activity of the major cell-wall synthesis machinery in E. coli

    Gizem Özbaykal et al.
    For initiation of cell-wall insertion, the cross-linking enzyme PBP2 stably binds to a component of the cell envelope that is different from MreB filaments.

    High-speed motility originates from cooperatively pushing and pulling flagella bundles in bilophotrichous bacteria

    Klaas Bente et al.
    Bacteria reach swimming speeds of several hundred body lengths per second and change direction in less than 5 ms by using coordinated flagella bundle agitation.

    Tuning movement for sensing in an uncertain world

    Chen Chen et al.
    Animals work in a world full of surprises, where using energy to position sensors proportional to the location's expected information avoids the pitfalls of positioning them at the information maxima.

    A missense in HSF2BP causing primary ovarian insufficiency affects meiotic recombination by its novel interactor C19ORF57/BRME1

    Natalia Felipe-Medina et al.
    Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.
