    Empirical single-cell tracking and cell-fate simulation reveal dual roles of p53 in tumor suppression

    Ann Rancourt, Sachiko Sato, Masahiko S Satoh
    Single-cell tracking and cell-fate simulation suggest that low levels of p53 suppress aneuploid cell formation in unstressed cells and also reveal the dual fate of cells lacking p53 in the presence of p53-proficient cells.

    An incentive circuit for memory dynamics in the mushroom body of Drosophila melanogaster

    Evripidis Gkanias, Li Yan McCurdy ... Barbara Webb
    Modelling differential roles for identified dopaminergic and output neurons of the fruit fly mushroom bodies, combined with a novel dopaminergic plasticity rule, explains neural and behavioural phenomena in olfactory learning tasks.

    A stochastic neuronal model predicts random search behaviors at multiple spatial scales in C. elegans

    William M Roberts, Steven B Augustine ... Shawn R Lockery
    A stochastic model of locomotory control in C. elegans based on an extensive new set of tracking data can explain and predict effects of ablations and mutations on behavior.

    Controlling opioid receptor functional selectivity by targeting distinct subpockets of the orthosteric site

    Rajendra Uprety, Tao Che ... Susruta Majumdar
    The structure-based design established a new approach to control pathway-selective activation of opioid receptors, resulting in new dual MOR/KOR G-protein biased agonist analgesics with attenuated liabilities.

    A parameterized two-domain thermodynamic model explains diverse mutational effects on protein allostery

    Zhuang Liu, Thomas G Gillis ... Qiang Cui
    A combined theoretical and experimental study revealed the mechanistic and structural basis of mutational effects on allostery and provided insights into the intrinsic connection of intra- and inter-domain properties.

    The transition state and regulation of γ-TuRC-mediated microtubule nucleation revealed by single molecule microscopy

    Akanksha Thawani, Michael J Rale ... Sabine Petry
    Four αβ-tubulin dimers associate laterally on γ-TuRC to define the rate-limiting transition state for microtubule nucleation.

    Fundamental bound on the persistence and capacity of short-term memory stored as graded persistent activity

    Onur Ozan Koyluoglu, Yoni Pertzov ... Ila R Fiete
    A fundamental lower-bound on memory recall precision, which declines with storage duration and number of stored items, is derived, and human performance is shown to be well-fit by this theoretical bound.

    Precise control of neural activity using dynamically optimized electrical stimulation

    Nishal Pradeepbhai Shah, AJ Phillips ... EJ Chichilnisky
    A novel method of electrical stimulation to precisely control neural activity for sensory restoration exhibits improvements in visual stimulus reconstruction, enables efficient hardware design, and extends to naturalistic conditions.

    Ordered patterning of the sensory system is susceptible to stochastic features of gene expression

    Ritika Giri, Dimitrios K Papadopoulos ... Richard W Carthew
    How gene expression noise is regulated is critical for cell fate and tissue patterning.

    Cerebellar involvement in an evidence-accumulation decision-making task

    Ben Deverett, Sue Ann Koay ... Samuel S-H Wang
    In a new evidence-accumulation decision-making task, activity of the lateral posterior cerebellum is necessary for accurate performance, and somatic and dendritic activity in Purkinje cells contains choice/evidence and error-related information.
