    Lipid droplet biology and evolution illuminated by the characterization of a novel perilipin in teleost fish

    James G Granneman et al.
    Phylogenetic, biochemical, and genetic techniques reveal a novel and ancient member of the Perilipin family, termed Plin6, that functions to concentrate and traffic lipophilic skin pigment in teleost fish.

    Neural activity in a hippocampus-like region of the teleost pallium is associated with active sensing and navigation

    Haleh Fotowat et al.
    Sparse firing in a hippocampus-like structure of the teleost telencephalon is linked to spatial navigation and active sensing.

    Segmentation of the zebrafish axial skeleton relies on notochord sheath cells and not on the segmentation clock

    Laura Lleras Forero et al.
    In contrast to amniotes, zebrafish (ray-finned fish, teleost) centra are formed from specialised notochord sheath cells, and the segmental patterning of these cells is independent of the segmentation clock.

    The Natural History of Model Organisms: Advancing biology through a deeper understanding of zebrafish ecology and evolution

    David M Parichy
    The zebrafish is a premier model organism for biomedical research, with a rich array of tools and genomic resources, and combining these with a fuller appreciation of wild zebrafish ecology could greatly extend its utility in biological research.

    Meiotic Recombination: Birth and death of a protein

    Julie Clément, Bernard de Massy
    The ways in which recombination sites are determined during meiosis are becoming clearer following a phylogenomic analysis for 225 different species.

    Limited dishevelled/Axin oligomerization determines efficiency of Wnt/β-catenin signal transduction

    Wei Kan et al.
    In vitro and in cellulo characterization of oligomerization by the cytoplasmic Wnt effector dishevelled and its partner Axin provide new mechanistic principles for Wnt/β-catenin signaling.

    Cryo-EM structures of S-OPA1 reveal its interactions with membrane and changes upon nucleotide binding

    Danyang Zhang et al.
    GTP binding induces rearrangement of S-OPA1 assembly on membrane and thus triggers membrane remodeling with reduced curvature.
