Cover photograph: Artistic representation of Acinetobacter baumannii infecting the lung. During infection, A. baumannii (green) competes with the host cells (red) for nutrient metals such as zinc (gray). As described by Hesse et al. in this issue, A. baumannii acquires zinc and causes disease using the Znu system, depicted in the image actively importing zinc. The image was generated by Ayomide Sanusia, a Vanderbilt University undergraduate student, as part of the ArtLab program. This program places students in laboratories as part of an Artist-in-Residence program where they generate art relevant to the laboratory's ongoing research (https://artlabvanderbilt.com/).
