    Multiplexed microfluidic screening of bacterial chemotaxis

    Michael R Stehnach, Richard J Henshaw ... Jeffrey S Guasto
    A multiplexed microfluidic device was developed to facilitate high-throughput screening of bacterial chemotaxis on a single chip and demonstrated across a range of microbes, chemostimulants, and chemical gradient conditions.

    Phenotyping single-cell motility in microfluidic confinement

    Samuel A Bentley, Hannah Laeverenz-Schlogelhofer ... Kirsty Y Wan
    A droplet microfluidics approach to stably trap and phenotype individual micron-sized algae reveals their distinct but stereotyped movement patterns and how they respond in real time to local environmental cues, including novel boundary circling behaviour under strong confinement.

    Microfluidic-based mini-metagenomics enables discovery of novel microbial lineages from complex environmental samples

    Feiqiao Brian Yu, Paul C Blainey ... Stephen R Quake
    Microfluidic-based mini-metagenomics enables the investigation of environmental microbial communities in high-throughput and with single-cell resolution, facilitating genome binning and quantification of function, abundance, and genome variation.

    Exploration of drug resistance mechanisms in triple negative breast cancer cells using a microfluidic device and patient tissues

    Wanyoung Lim, Inwoo Hwang ... Sungsu Park
    A microfluidic device induces doxorubicin-resistant polyaneuploid cancer cells from triple negative breast cancer cells, revealing NUPR1/HDAC11 axis dysfunction drives chemoresistance, increasing tumor heterogeneity and impacting clinical outcomes.

    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.

    Initiation of chromosome replication controls both division and replication cycles in E. coli through a double-adder mechanism

    Guillaume Witz, Erik van Nimwegen, Thomas Julou
    Single-cell measurements combined with a new statistical framework for discriminating between models of cell cycle regulation show that chromosome initiation controls the E. coli cell cycle via two adder mechanisms.

    An aging-independent replicative lifespan in a symmetrically dividing eukaryote

    Eric C Spivey, Stephen K Jones Jr ... Ilya J Finkelstein
    A high throughput, full lifespan microscopic analysis reveals that fission yeast does not age but has a finite replicative lifespan.
