    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.

    Distinct neural contributions to metacognition for detecting, but not discriminating visual stimuli

    Matan Mazor et al.
    Combining psychophysics and functional MRI reveals a qualitative asymmetry in neural engagement when reflecting on whether a stimulus is seen (detection) compared to reflecting on what a stimulus is (discrimination).

    In vivo assessment of the neural substrate linked with vocal imitation accuracy

    Julie Hamaide et al.
    Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.
