    Structural model for differential cap maturation at growing microtubule ends

    Juan Estévez-Gallego et al.
    The tubulin GTPase cycle structurally modulates the microtubule cap, causing lattice expansion, which is an intermediate state involved in phosphate release and regulatory signaling.

    Importance of miRNA stability and alternative primary miRNA isoforms in gene regulation during Drosophila development

    Li Zhou et al.
    Selective degradation of mature miRNAs shapes temporal miRNA expression patterns and is important for proper regulation of target genes to support normal development of Drosophila embryos.

    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.

    Intrinsic cooperativity potentiates parallel cis-regulatory evolution

    Trevor R Sorrells et al.
    Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

    Non-invasive detection of urothelial cancer through the analysis of driver gene mutations and aneuploidy

    Simeon U Springer et al.
    The creation of a non-invasive assay for detecting urothelial cancer could have a profound impact on how we find and treat the disease.
