    Evolution of brilliant iridescent feather nanostructures

    Klara Katarina Nordén, Chad M Eliason, Mary Caswell Stoddard
    Despite having different shapes and structures, the melanosomes (melanin-packed organelles) in bird feathers often produce thin melanin layers, giving rise to brilliant iridescence.

    Membrane transporter dimerization driven by differential lipid solvation energetics of dissociated and associated states

    Rahul Chadda, Nathan Bernhardt ... Janice L Robertson
    Differences in the lipid solvation energetics of associated and dissociated states is a primary driving force for membrane protein oligomerization, presenting a molecular mechanism for lipid regulation in biology.

    Asymmetric localization of the cell division machinery during Bacillus subtilis sporulation

    Kanika Khanna, Javier Lopez-Garrido ... Elizabeth Villa
    During sporulation, FtsAZ filaments mediating cell division in Bacillus subtilis are positioned asymmetrically around the septum only on the mother cell side, making the septum thinner than during vegetative growth.

    Microstructural differences in the osteochondral unit of terrestrial and aquatic mammals

    Irina AD Mancini, Riccardo Levato ... Jos Malda
    Analysis of the osteochondral unit of aquatic mammals reveals a distinctly different tissue structure, lacking the arcade-like collagen fiber organization, a calcified cartilage layer and a dense subchondral bone plate, typically seen in osteochondral tissue of terrestrial mammals.

    Unexpected plasticity in the life cycle of Trypanosoma brucei

    Sarah Schuster, Jaime Lisack ... Markus Engstler
    Parasite life cycles may be more flexible than traditionally thought, potentially allowing single-cell infections of insect vectors and transmission between hosts even at very low parasite densities.

    The role of sigma 1 receptor in organization of endoplasmic reticulum signaling microdomains

    Vladimir Zhemkov, Jonathon A Ditlev ... Ilya Bezprozvanny
    Signaling function of sigma 1 receptor is related to its ability to organize cholesterol-enriched microdomains in the endoplasmic reticulum membrane.

    A mammalian Wnt5a–Ror2–Vangl2 axis controls the cytoskeleton and confers cellular properties required for alveologenesis

    Kuan Zhang, Erica Yao ... Pao-Tien Chuang
    Regulation of cellular properties such as ligand secretion and migratory ability through changes in the cytoskeleton mediated by a Wnt5a–Ror2–Vangl2 axis is a major determinant of alveolar formation.

    Attention-deficit hyperactivity disorder symptoms and brain morphology: Examining confounding bias

    Lorenza Dall'Aglio, Hannah H Kim ... Henning Tiemeier
    Approximately half of the associations identified between attention-deficit/hyperactivity disorder and brain morphology in two large independent studies of adolescents are likely due to confounding bias by socioeconomic and parental behavioral factors.

    Development and evaluation of a live birth prediction model for evaluating human blastocysts from a retrospective study

    Hang Liu, Zhuoran Zhang ... Yu Sun
    The inclusion of the patient couple's clinical features along with blastocyst images increases live birth prediction accuracy.
