    Genomic evidence for global ocean plankton biogeography shaped by large-scale current systems

    Daniel J Richter, Romain Watteaux ... Olivier Jaillon
    Analysis of genomic DNA composition of surface plankton communities reveals a stable, ocean basin-scale plankton biogeography that emerges from the intertwined effects of environmental variations and currents.

    Adaptive coding for dynamic sensory inference

    Wiktor F Młynarski, Ann M Hermundstad
    To make reliable but metabolically efficient perceptual inferences in a changing world, neural systems should dynamically adapt based on surprise and uncertainty about the sensory environment.

    Threat of shock increases excitability and connectivity of the intraparietal sulcus

    Nicholas L Balderston, Elizabeth Hale ... Christian Grillon
    Multimodal neuroimaging was used to study the effect of threat on spontaneous brain activity and functional connectivity, and demonstrated that threat increases both activity and connectivity of the intraparietal sulcus, a key node in the frontoparietal attention network.

    The emergence of visual category representations in infants’ brains

    Xiaoqian Yan, Sarah Shi Tung ... Kalanit Grill-Spector
    Scalp electroencephalography combined with a frequency tagging method reveals that distinct responses to daily categories emerge at different ages in infants.

    Neural interactions in the human frontal cortex dissociate reward and punishment learning

    Etienne Combrisson, Ruggero Basanisi ... Andrea Brovelli
    Reward and punishment learning is represented in partly overlapping regions of the brain while relying on specific intra- and inter-regional interactions.

    Role of the pre-initiation complex in Mediator recruitment and dynamics

    Elisabeth R Knoll, Z Iris Zhu ... Randall H Morse
    Genome-wide recruitment of Mediator and Pol II is reduced in yeast lacking the Med2-Med3-Med15 tail module triad, and Mediator association with gene promoters depends on Pol II, Taf1, and TBP.

    Increased longevity due to sexual activity in mole-rats is associated with transcriptional changes in the HPA stress axis

    Arne Sahm, Matthias Platzer ... Philip Dammann
    The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

    Mesoscale cortex-wide neural dynamics predict self-initiated actions in mice several seconds prior to movement

    Catalin Mitelut, Yongxu Zhang ... Timothy H Murphy
    Mouse self-initiated behaviors can be identified seconds prior to action and have similar neuro-dynamical structure to neural dynamics underlying human voluntary actions supporting the use of mouse models in self-initiated and volitional action research.

    Subpopulations of neurons in lOFC encode previous and current rewards at time of choice

    David L Hocker, Carlos D Brody ... Christine M Constantinople
    A distinct subpopulation of neurons in the rat orbitofrontal cortex encodes reward history at the time of choice, providing a potential neural substrate by which reward history may influence decisions.

    Convergence between the microcosms of Southeast Asian and North American pitcher plants

    Leonora S Bittleston, Charles J Wolock ... Anne Pringle
    Host characteristics drive the assembly of similar communities within the convergently evolved and geographically distant pitcher ecosystems of carnivorous pitcher plants.
