    Whole genome phylogenies reflect the distributions of recombination rates for many bacterial species

    Thomas Sakoparnig, Chris Field, Erik van Nimwegen
    For many bacterial species, recombination dominates genome evolution and phylogenetic patterns that have so far been assumed to reflect clonal relationships, in fact reflect variation in recombination rates across lineages.

    Transversal functional connectivity and scene-specific processing in the human entorhinal-hippocampal circuitry

    Xenia Grande, Magdalena M Sauvage ... David Berron
    The human entorhinal-hippocampal circuitry is characterized by an information-specific functional organization where two routes, that are preferentially connected to the parahippocampal cortex or the perirhinal and retrosplenial cortices, divide the entorhinal cortex as well as hippocampal subiculum and CA1 subregions.

    Small RNAs from mitochondrial genome recombination sites are incorporated into T. gondii mitoribosomes

    Sabrina Tetzlaff, Arne Hillebrand ... Christian Schmitz-Linneweber
    Sequences at mitochondrial genome recombination sites are dually used as mRNAs and as rRNAs in actively translating mitoribosomes of T. gondii.

    Single-amino acid variants reveal evolutionary processes that shape the biogeography of a global SAR11 subclade

    Tom O Delmont, Evan Kiefl ... A Murat Eren
    An in-depth metagenomic analysis of possibly the most abundant and widespread microbial lineage in the surface ocean teases apart evolutionary processes that maintain its genomic heterogeneity and biogeography.

    Learning to stand with unexpected sensorimotor delays

    Brandon G Rasman, Patrick A Forbes ... Jean-Sébastien Blouin
    The nervous system can learn to control standing balance with added sensorimotor delays by causally linking delayed whole-body sensory feedback, initially deemed as unexpected, to self-generated balance motor commands.

    Using light and X-ray scattering to untangle complex neuronal orientations and validate diffusion MRI

    Miriam Menzel, David Gräßel ... Marios Georgiadis
    Light and X-ray scattering on the same primate and human brain samples cross-validate each other and enable accurate mapping of axonal trajectories in regions with uni- and multi-directional nerve fibers, which can be used to validate diffusion MRI.

    Dynamics of cooperative excavation in ant and robot collectives

    S Ganga Prasath, Souvik Mandal ... L Mahadevan
    Observations of ant excavation from a confining corral, along with theoretical models and synthetic robot experiments show the emergence of cooperation induced by pheromones in a malleable environment that is moulded by and moulds collective behavior.

    Decoding contextual influences on auditory perception from primary auditory cortex

    Bernhard Englitz, Sahar Akram ... Shihab Shamma
    The perception of ambiguous steps in relative tone height is predicted by direction-selective cells in the auditory cortex, rather than the brain's represented distance between the tone heights.
    1. Neuroscience

    I-Spin live, an open-source software based on blind-source separation for real-time decoding of motor unit activity in humans

    Julien Rossato, François Hug ... Simon Avrillon
    I-Spin enables researchers to decode motor unit firings from surface and intramuscular electromyographic signals in real time.

    GLI1 facilitates collagen-induced arthritis in mice by collaborative regulation of DNA methyltransferases

    Gaoran Ge, Qianping Guo ... Dechun Geng
    A new role is identified for GLI1 in modulating the inflammatory response of macrophages and the overaction of osteoclasts in collagen-induced arthritis by collaboratively regulating DNMT1 and DNMT3a.
