    Local generation and efficient evaluation of numerous drug combinations in a single sample

    Vlad Elgart, Joseph Loscalzo
    Engineered local heterogeneity in drug concentration is used as a tool to encode drug treatment regimens and to predict the macroscopic cellular response to drug perturbations.

    Simultaneous recording of multiple cellular signaling events by frequency- and spectrally-tuned multiplexing of fluorescent probes

    Michelina Kierzek, Parker E Deal ... Christoph Brenker
    FASTM is a novel technique that leverages phase-sensitive signal detection for time-resolved multiplexing of probes with millisecond time resolution, opening new opportunities for interrogating rapid cellular signaling and (bio)chemical reactions.

    The cyanobacterial circadian clock follows midday in vivo and in vitro

    Eugene Leypunskiy, Jenny Lin ... Michael J Rust
    The cyanobacterial core clock tracks midday regardless of day length, which can be understood in terms of a model for how the environment alters the clock limit cycle.

    Nanoscopic anatomy of dynamic multi-protein complexes at membranes resolved by graphene-induced energy transfer

    Nadia Füllbrunn, Zehao Li ... Changjiang You
    The axial organization and dynamics of the HOPS complex at membrane surface are resolved by graphene-induced energy transfer with subnanometer resolution.

    Exploring the role of macromolecular crowding and TNFR1 in cell volume control

    Parijat Biswas, Priyanka Roy ... Deepak Kumar Sinha
    Cells adapt to extracellular hypertonicities using regulatory volume increase (RVI), and TNFR1-mediated NFkB activation is indispensable for RVI, but the increased cytoplasmic macromolecular crowding can inhibit TNFR1 signaling and prevent RVI at severe hypertonicities.

    An empirical energy landscape reveals mechanism of proteasome in polypeptide translocation

    Rui Fang, Jason Hon ... Ying Lu
    Empirical energy landscape allows simulating the structural dynamics of the proteasomal ATPase complex, which yields predictions that are widely consistent with experimental observations and reveals the functional mechanism of the proteasome in substrate degradation.

    Predictably manipulating photoreceptor light responses to reveal their role in downstream visual responses

    Qiang Chen, Norianne T Ingram ... Fred Rieke
    Quantitative models for responses of rod and cone photoreceptors are developed that allow direct tests of the impact of the photoreceptors on responses of downstream visual neurons.

    A predictive focus of gain modulation encodes target trajectories in insect vision

    Steven D Wiederman, Joseph M Fabian ... David C O’Carroll
    Visual neurons in the dragonfly predict the path of a moving target, even when it is occluded or crosses from one eye to the other.
