    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills et al.
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    A mechanism for the extension and unfolding of parallel telomeric G-quadruplexes by human telomerase at single-molecule resolution

    Bishnu P Paudel et al.
    Human telomerase unfolds and extends parallel G-quadruplexes using a unique mechanism involving its RNA template.

    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.

    LIS1 determines cleavage plane positioning by regulating actomyosin-mediated cell membrane contractility

    Hyang Mi Moon et al.
    Novel insights into LIS1-dependent regulation of cell membrane contractility and cleavage axis specification identify a key molecular network regulating mitoses of neural progenitors and somatic cells during development.

    Extracellular matrix-inducing Sox9 promotes both basal progenitor proliferation and gliogenesis in developing neocortex

    Ayse Güven et al.
    Transcription factor Sox9 has an important role in neocortex expansion, where its expression in basal progenitors increases proliferation, induces premature gliogenesis and promotes the expression of extracellular matrix components.

    Fluorescent sensors reporting the activity of ammonium transceptors in live cells

    Roberto De Michele et al.
    A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.

    Sequestration and activation of plant toxins protect the western corn rootworm from enemies at multiple trophic levels

    Christelle AM Robert et al.
    The western corn rootworm escapes biological control by entomopathogenic nematodes by partitioning and phenocopying the plant defense system for self-protection.

    Optical electrophysiology for probing function and pharmacology of voltage-gated ion channels

    Hongkang Zhang et al.
    Optogenetic tools enable sophisticated measurements of a voltage-gated sodium channel implicated in pain, as well as high-throughput screening of candidate channel blockers.

    Umbilical cord blood-derived ILC1-like cells constitute a novel precursor for mature KIR+NKG2A- NK cells

    Sabrina Bianca Bennstein et al.
    Neonatal ILC1-like cells are functionally immature but have the unique potential to generate NK cells characterized by downregulation of NKG2A and a highly diverse KIR receptor repertoire.

    Atomic structure of a mitochondrial complex I intermediate from vascular plants

    Maria Maldonado et al.
    The first atomic resolution structure of a mitochondrial respiratory complex from plants provides insight into the assembly and evolution of respiration in autotrophic eukaryotes.
