    Interplay of surface interaction and magnetic torque in single-cell motion of magnetotactic bacteria in microfluidic confinement

    Agnese Codutti, Mohammad A Charsooghi ... Stefan Klumpp
    Confined magnetotactic bacteria exhibit circling and U-turn trajectories explained by a competition of alignment with a magnetic field and alignment along the confining walls as well as considerable cell-to-cell heterogeneity.

    Amoxicillin-resistant Streptococcus pneumoniae can be resensitized by targeting the mevalonate pathway as indicated by sCRilecs-seq

    Liselot Dewachter, Julien Dénéréaz ... Jan-Willem Veening
    High-throughput single-cell based, genome-wide gene silencing screening (sCRilecs-seq) revealed that drugging the mevalonate pathway resensitizes amoxicillin-resistant pneumococci.
