    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon et al.
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    Lunatic fringe-mediated Notch signaling regulates adult hippocampal neural stem cell maintenance

    Fatih Semerci et al.
    In adult mouse hippocampus, neural stem cell and their progeny communicate via Lunatic Fringe mediated Notch signaling to regulate stem cell quiescence, division, and fate.

    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.

    IgM and IgD B cell receptors differentially respond to endogenous antigens and control B cell fate

    Mark Noviski et al.
    Self-reactive B cells downregulate the IgM but not the IgD B cell receptor, and this serves as a critical tolerance mechanism because IgD is less sensitive to bona fide endogenous antigens than IgM.

    The need for high-quality oocyte mitochondria at extreme ploidy dictates mammalian germline development

    Marco Colnaghi et al.
    Selective transfer of mitochondria in the Balbiani body ensures high-quality oocyte mitochondria at extreme ploidy, explaining many enigmatic features of female germline architecture including germ cell loss.

    Topological constraints in early multicellularity favor reproductive division of labor

    David Yanni et al.
    Mathematical modeling shows that reproductive specialization is strongly favored in sparse networks of cellular interactions that reflect the morphology of early multicellular organisms, even when benefits of specialization are saturating.

    Intra-species differences in population size shape life history and genome evolution

    David Willemsen et al.
    Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.

    Yap1 safeguards mouse embryonic stem cells from excessive apoptosis during differentiation

    Lucy LeBlanc et al.
    During ES cell differentiation, Yap1 directly regulates apoptosis-related genes like Bcl-2 and Mcl-1 to attenuate apoptosis and promote cell survival to allow for successful cell fate changes.

    Heterogeneity of murine periosteum progenitors involved in fracture healing

    Brya G Matthews et al.
    Murine periosteum is highly enriched for osteoprogenitors, many of which express αSMA, but fracture callus chondrocytes are partially derived from other sources.

    Loss of Kat2a enhances transcriptional noise and depletes acute myeloid leukemia stem-like cells

    Ana Filipa Domingues et al.
    Histone acetyl-transferase Kat2a preserves leukemia stem cells through frequent transcriptional firing of metabolic and regulatory gene promoters and maintenance of a largely invariant self-renewal program.
