    Bmal1 function in skeletal muscle regulates sleep

    J Christopher Ehlen et al.
    Expression of transcription factor BMAL1 in skeletal muscle reduces the recovery response to sleep loss and is both necessary and sufficient to regulate total sleep amount.

    Regulating G protein-coupled receptors by topological inversion

    Bray Denard et al.
    Multiple biochemical assays show that the topology of CCR5 and possibly other GPCRs may be inverted by ceramide or other sphingolipids through the process of regulated alternative translocation.

    Two-photon calcium imaging of the medial prefrontal cortex and hippocampus without cortical invasion

    Masashi Kondo et al.
    Establishment of two-photon imaging with a 1100-nm laser, which underfills the objective's back aperture, detects activity of multiple neurons in the prelimbic area and hippocampal CA1 region of the intact mouse brain.

    Transient rapamycin treatment can increase lifespan and healthspan in middle-aged mice

    Alessandro Bitto et al.
    Three months treatment with the drug rapamycin increases lifespan, alters cancer prevalence, remodels the microbiome, and improves functional measures of health in middle aged mice in a dose- and sex-dependent manner.

    Determination of ubiquitin fitness landscapes under different chemical stresses in a classroom setting

    David Mavor et al.
    Chemical perturbation-dependent deep mutational scanning data collected by a lab-based interdisciplinary graduate class resolves a paradox between the high evolution conservation and the high mutational tolerance of the protein ubiquitin.

    First quantitative high-throughput screen in zebrafish identifies novel pathways for increasing pancreatic β-cell mass

    Guangliang Wang et al.
    A novel high-throughput, whole organism chemical screening platform was used to identify existing drugs that increase pancreatic beta-cell mass in zebrafish, implicating unique roles for the NF-κB and serotonergic signaling pathways in regulating pancreatic biology.

    Actin filaments target the oligomeric maturation of the dynamin GTPase Drp1 to mitochondrial fission sites

    Wei-ke Ji et al.
    A key cellular process is controlled by altering a balance, rather than through an off/on mechanism.

    Acknowledging selection at sub-organismal levels resolves controversy on pro-cooperation mechanisms

    Wenying Shou
    Building on previous work (Momeni et al., 2013), it is shown that recognizing the hierarchical organization of biological systems resolves the ongoing controversy on pro-cooperation mechanisms.

    KRAS-dependent sorting of miRNA to exosomes

    Diana J Cha et al.
    In isogenically matched colorectal cancer (CRC) cell lines, mutant KRAS alters the composition of secreted miRNAs in extracellular vesicles that can then transfer repressive activity to wild type cells.

    Integrated β-catenin, BMP, PTEN, and Notch signalling patterns the nephron

    Nils O Lindström et al.
    The patterning of the nephron is driven by a gradient in the activity of β-catenin and further defined by a network of BMP, PTEN and NOTCH signalling.
