    The African ape-like foot of Ardipithecus ramidus and its implications for the origin of bipedalism

    Thomas Cody Prang
    The most recent common ancestor of humans, chimpanzees, and bonobos possessed a foot adapted to terrestrial quadrupedalism and climbing.

    Radially patterned cell behaviours during tube budding from an epithelium

    Yara E Sanchez-Corrales et al.
    Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.

    Anisotropic growth is achieved through the additive mechanical effect of material anisotropy and elastic asymmetry

    Firas Bou Daher et al.
    Growing upwards in the young seedling is controlled by two cooperative mechanical mechanisms: cellulose orientation in inner tissues and differential elasticity in epidermal cells.

    Dynamics of genomic innovation in the unicellular ancestry of animals

    Xavier Grau-Bové et al.
    The foundations of genomic complexity in multicellular animals have deep roots in their unicellular prehistory, both in terms of innovations in gene content, as well as the evolutionary dynamics of genome architecture.

    Live cell-lineage tracing and machine learning reveal patterns of organ regeneration

    Oriol Viader-Llargués et al.
    A combination of live cell tracking, cell-lineage tracing and machine learning shows that injured sensory organs repair accurately regardless of the extent of damage.

    Non-thalamic origin of zebrafish sensory nuclei implies convergent evolution of visual pathways in amniotes and teleosts

    Solal Bloch et al.
    Mesencephalic origin of the zebrafish thalamocortical-like visual projection neurons indicates independent evolution of tectofugal visual pathways in amniotes and teleosts.

    Origin of a folded repeat protein from an intrinsically disordered ancestor

    Hongbo Zhu et al.
    Minimal changes allow an ancestral, unfolded peptide to adopt a known fold by repetition, illuminating a possible path for the emergence of folded proteins at the origin of life.

    Zebrafish macrophage developmental arrest underlies depletion of microglia and reveals Csf1r-independent metaphocytes

    Laura E Kuil et al.
    Embryonic and definitive macrophages require colony-stimulating factor 1 receptor, whereas non-hematopoietic metaphocytes that resemble macrophages do not, explaining the relative high numbers of putative macrophages in Csf1r-deficient zebrafish.

    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite et al.
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.
