    Presynaptic morphology and vesicular composition determine vesicle dynamics in mouse central synapses

    Laurent Guillaud et al.
    In central synapses, the mobility and supply of synaptic vesicles are determined by two independent biological factors: the morphological and structural organization of nerve terminals and the molecular signature of vesicles.

    Operon mRNAs are organized into ORF-centric structures that predict translation efficiency

    David H Burkhardt et al.
    Operonic mRNAs in bacteria are comprised of ORF (open reading frame)-wide units of secondary structure, which are intrinsically distinct between adjacent ORFs and encode a rough blueprint for ORF-specific translation efficiency.

    Transcriptome analysis illuminates the nature of the intracellular interaction in a vertebrate-algal symbiosis

    John A Burns et al.
    The endosymbiosis between an alga and the spotted salamander shows several parallels to invertebrate-algal symbioses as well as to pathogen associations in vertebrate animals.

    Motor control of Drosophila feeding behavior

    Olivia Schwarz et al.
    The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.

    Genome mining unearths a hybrid nonribosomal peptide synthetase-like-pteridine synthase biosynthetic gene cluster

    Hyun Bong Park et al.
    A new type of hybrid nonribosomal peptide synthetase (NRPS)-like-pteridine synthase biosynthetic pathway has been illuminated via genome mining.

    Astrocyte morphology is confined by cortical functional boundaries in mammals ranging from mice to human

    Raya Eilam et al.
    The structural morphology of astrocyte processes is constrained by functional boundaries in the mouse, rat and human cortex.

    Unipolar distributions of junctional Myosin II identify cell stripe boundaries that drive cell intercalation throughout Drosophila axis extension

    Robert J Tetley et al.
    Analysing Myosin II unipolar planar polarisation with high spatial and temporal resolution during Drosophila axis extension reveals how tissue boundaries drive polarized cell intercalation while limiting cell mixing.

    Ensemble cryo-EM uncovers inchworm-like translocation of a viral IRES through the ribosome

    Priyanka D Abeyrathne et al.
    An ensemble of cryo-EM structures reveals how eukaryotic elongation factor 2 positions the first codon of a viral mRNA for translation.

    Odor-identity dependent motor programs underlie behavioral responses to odors

    Seung-Hye Jung et al.
    Flies respond to odors by modulating multiple independently modulated motor programs.
