    The roles of history, chance, and natural selection in the evolution of antibiotic resistance

    Alfonso Santos-Lopez, Christopher W Marshall ... Vaughn S Cooper
    Selection imposed by antibiotics may dominate evolutionary forces acting on opportunistic pathogens like Acinetobacter baumannii, yet chance effects and a prior history in biofilm may constrain resistance and impose collateral sensitivities.

    A CTP-dependent gating mechanism enables ParB spreading on DNA

    Adam SB Jalal, Ngat T Tran ... Tung BK Le
    A structural and biochemical approach shows that CTP binding and hydrolysis regulate nucleation, spreading, and recycling of a chromosome segregation protein ParB.

    Effect of malaria parasite shape on its alignment at erythrocyte membrane

    Anil K Dasanna, Sebastian Hillringhaus ... Dmitry A Fedosov
    A numerical model of malaria parasite adhesion to an erythrocyte shows that the original egg-like shape of merozoites is more robust than other shapes in negotiating various physiological conditions during the alignment process upon erythrocyte invasion.

    Transcriptomics-informed large-scale cortical model captures topography of pharmacological neuroimaging effects of LSD

    Joshua B Burt, Katrin H Preller ... John D Murray
    Computational models of large-scale cortical dynamics, integrating gene expression mapping to pattern pharmacological modulation across cortex, capture inter-areal topographies of functional connectivity alterations induced by lysergic acid diethylamide, providing a framework for simulating effects of pharmacology in the human brain.

    The GNU subunit of PNG kinase, the developmental regulator of mRNA translation, binds BIC-C to localize to RNP granules

    Emir E Avilés-Pagán, Masatoshi Hara, Terry L Orr-Weaver
    The Drosophila PNG kinase controls mRNA translation at the oocyte-to-embryo transition, and its GNU activating subunit is shown here to bind translational repressors and be a component of RNP granules.

    A locomotor neural circuit persists and functions similarly in larvae and adult Drosophila

    Kristen Lee, Chris Q Doe
    Descending interneurons maintain synaptic connectivity and behavioral function despite pruning during metamorphosis, showing that synaptic specificity is established twice at different life stages.

    Spatiotemporal control of cell cycle acceleration during axolotl spinal cord regeneration

    Emanuel Cura Costa, Leo Otsuki ... Osvaldo Chara
    Computational modeling and a cell cycle-reporting axolotl reveal how spinal cord regeneration can be achieved by a signal that propagates 828 μm from the injury site during the first 85 hours post-amputation.

    Pleiotropic mutations can rapidly evolve to directly benefit self and cooperative partner despite unfavorable conditions

    Samuel Frederick Mock Hart, Chi-Chun Chen, Wenying Shou
    Mutations that directly benefit both self and cooperative partner can readily evolve to promote cooperation.

    Spontaneous neural synchrony links intrinsic spinal sensory and motor networks during unconsciousness

    Jacob Graves McPherson, Maria F Bandres
    Persistent, non-random sensorimotor connectivity reveals the capacity of intrinsic spinal networks to purposefully replay and modify learned patterns of neural transmission during unconsciousness.

    Punishment insensitivity in humans is due to failures in instrumental contingency learning

    Philip Jean-Richard-dit-Bressel, Jessica C Lee ... Gavan P McNally
    Punishment insensitive individuals are not more impulsive or anxious, they dislike aversive outcomes and predictors of these outcomes, but are simply less likely to learn their control over them.
