    Reversal of the adipostat control of torpor during migration in hummingbirds

    Erich R Eberts et al.
    Ruby-throated hummingbirds switch from using torpor to survive nighttime energy emergencies in the breeding season to using it to spare fat stores and gain premigratory mass in the late summer.

    A dual endosymbiosis supports nutritional adaptation to hematophagy in the invasive tick Hyalomma marginatum

    Marie Buysse et al.
    The invasive tick Hyalomma marginatum relies on a dual partner nutritional system to provide B vitamins and avoid nutritional deficiencies due to its exclusive blood diet.

    Mimicry can drive convergence in structural and light transmission features of transparent wings in Lepidoptera

    Charline Sophie Pinna et al.
    Wing transparency in mimetic butterflies and moths is achieved by an unexpected diversity of structural features, and both structures and light transmission properties of wings are under selection for convergence.

    Evolution of brilliant iridescent feather nanostructures

    Klara Katarina Nordén et al.
    Despite having different shapes and structures, the melanosomes (melanin-packed organelles) in bird feathers often produce thin melanin layers, giving rise to brilliant iridescence.

    Antigenic evolution of human influenza H3N2 neuraminidase is constrained by charge balancing

    Yiquan Wang et al.
    The local fitness landscape of an antigenic region in influenza neuraminidase was determined by combinatorial mutagenesis and next-generation sequencing.

    Single-cell RNA sequencing of the Strongylocentrotus purpuratus larva reveals the blueprint of major cell types and nervous system of a non-chordate deuterostome

    Periklis Paganos et al.
    Reconstruction of cell-type families in the purple sea urchin larva reveals unprecedented transcriptional diversity, stunning neuronal complexity and a missing link to pancreas evolution, suggesting this approach can be also used to uncover hidden cell type homologies.

    Mutation saturation for fitness effects at human CpG sites

    Ipsita Agarwal, Molly Przeworski
    Methylated CpG sites are saturated for T mutations in a sample of 390K human exomes, providing a test case for inferences about fitness effects in human genes, and insight into the interpretation of mutations as pathogenic using reference datasets.
