    Auditory synapses to song premotor neurons are gated off during vocalization in zebra finches

    Kosuke Hamaguchi et al.
    Intracellular recordings in singing birds and images of synapses in deafened birds provide insights into the neural circuitry that enables songbirds to fine-tune their songs.

    Genome-wide dynamics of Pol II elongation and its interplay with promoter proximal pausing, chromatin, and exons

    Iris Jonkers et al.
    The elongation rate of RNA Polymerase II varies greatly between and along genes, as this enzyme accelerates from stable pausing to rapid elongation within genes, and is influenced by CG-content, exons and chromatin.

    Characterization of TSET, an ancient and widespread membrane trafficking complex

    Jennifer Hirst et al.
    A missing link between the AP complexes and COPI sheds light on the evolution of vesicle coat proteins and trafficking pathways in the earliest eukaryotes.

    MicroRNAs shape circadian hepatic gene expression on a transcriptome-wide scale

    Ngoc-Hien Du et al.
    In the liver, microRNAs exert widespread functions in the modulation of phases and amplitudes of clock-controlled gene expression, but their influence on the core clock is remarkably mild.

    Mismatch repair deficiency endows tumors with a unique mutation signature and sensitivity to DNA double-strand breaks

    Hui Zhao et al.
    A comprehensive catalogue of somatic mutations accumulating in MMR-deficient tumors highlights their relevance in the context of human genetic evolution, for the diagnosis of microsatellite instability and the provision of targeted treatment options.

    Identification of the transcription factor ZEB1 as a central component of the adipogenic gene regulatory network

    Carine Gubelmann et al.
    A large-scale transcription factor screen reveals over twenty novel adipogenic regulators: most notably ZEB1, which exerts essential transcriptional control of fat cell differentiation.

    Multi-species, multi-transcription factor binding highlights conserved control of tissue-specific biological pathways

    Benoit Ballester et al.
    Combinatorial transcription factor binding shared by multiple species enriches for essential biological pathways and coincides with disease-causing regulatory DNA mutations.

    Kinetic competition during the transcription cycle results in stochastic RNA processing

    Antoine Coulon et al.
    Real-time single-molecule visualization of transcription and splicing in living cells reveals that RNA synthesis and processing can occur through multiple pathways on the same gene.

    miR-142 regulates the tumorigenicity of human breast cancer stem cells through the canonical WNT signaling pathway

    Taichi Isobe et al.
    Insights into the roles and mechanisms of two of the miRNAs upregulated in human breast cancer stem cells in at least some breast cancers are presented.

    Homeostatic reinforcement learning for integrating reward collection and physiological stability

    Mehdi Keramati, Boris Gutkin
    A mathematical model built around the assumption that the desire to maintain internal homeostasis drives the behavior of animals, by affecting their learning processes, can explain many real-world behaviors, including some that might otherwise appear irrational.
