    Temporal dynamics and developmental memory of 3D chromatin architecture at Hox gene loci

    Daan Noordermeer et al.
    Hox genes are activated sequentially and, at the same time, undergo a transition from an inactive to an active chromatin compartment, most likely to prevent posterior genes being activated too early.

    Multi-enhancer transcriptional hubs confer phenotypic robustness

    Albert Tsai et al.
    Multiple enhancers in physical proximity can reinforce shared transcriptional 'hubs' to preserve their transcriptional output, providing a buffer during environmental stresses and genetic perturbations to preserve phenotypic robustness.

    Disparate expression specificities coded by a shared Hox-C enhancer

    Steve W Miller, James W Posakony
    Tucked within a well-known story of diverging gene function is a single enhancer encoding two inseparable specificities that regulates two adjacent genes, each with different spatiotemporal expression patterns.

    Specific structural elements of the T-box riboswitch drive the two-step binding of the tRNA ligand

    Jiacheng Zhang et al.
    The glycine T-box riboswitch recognizes tRNAgly and senses its aminoacylation state by first interacting with the anticodon region and subsequently probing the 3' end of the ligand using both specific structural elements and conformational dynamics.

    The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

    Rita A Batista et al.
    Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.

    Chromatin-bound CRM1 recruits SET-Nup214 and NPM1c onto HOX clusters causing aberrant HOX expression in leukemia cells

    Masahiro Oka et al.
    A key molecule that connects leukemogenic proteins to aberrant HOX gene regulation turned out to be a nuclear export factor, CRM1.

    Sexual Differentiation: A matter of timing

    Michael W Perry, Claude Desplan
    A genetic pathway involved in development works together with the sex-determination pathway to control the timing of sexually dimorphic neural development in C. elegans.

    2018 Gairdner Awards: The past, present and future of light-gated ion channels and optogenetics

    Sheena A Josselyn
    Research into light-gated ion channels called channelrhodospins laid the foundations for the development of optogenetics, a technique that has gone on to revolutionize neuroscience.

    Extracellular Matrix: Sculpting new structures

    Jocelyn A McDonald, Yoshinori Tomoyasu
    The origins of the posterior lobe, a recently evolved structure in some species of Drosophila, have become clearer.

    Philosophy of Biology: The analysis of living systems can generate both knowledge and illusions

    Antony M Jose
    By thinking about experimental techniques in terms of six broad approaches – perturbation, visualization, substitution, characterization, reconstitution, and simulation – researchers may be able to generate more reliable inferences.
