    A billion years arms-race between viruses, virophages, and eukaryotes

    Jose Gabriel Nino Barreat, Aris Katzourakis
    Phylogenetic analyses of the four core virion proteins support a new evolutionary model for the origin of the main groups of eukaryotic viruses in the kingdom Bamfordvirae.

    Broad-scale variation in human genetic diversity levels is predicted by purifying selection on coding and non-coding elements

    David A Murphy, Eyal Elyashiv ... Guy Sella
    Background selection is shown to be the dominant mode of linked selection in humans, with marked effects on diversity levels throughout autosomes.

    Response to comment on 'A conserved strategy for inducing appendage regeneration in moon jellyfish, Drosophila, and mice'

    Yutian Li, Anish A Sarma ... Lea Goentoro
    We are writing to respond to the comment by Sustar and Tuthill, 2023 on our article about appendage regeneration in jellyfish, fruit flies, and mice (Abrams et al., 2021).

    Evolution of an extreme hemoglobin phenotype contributed to the sub-Arctic specialization of extinct Steller’s sea cows

    Anthony V Signore, Phillip R Morrison ... Kevin L Campbell
    Resurrected Steller’s sea cow hemoglobin exhibits novel functional traits underlying their adaptation to the sub-Arctic.

    Palaeontology: Sexual dimorphism in dinosaurs

    Stella A Ludwig, Roy E Smith, Nizar Ibrahim
    Studying fossils from a mass-mortality event reveals evidence for sexual dimorphism and, unusually, equal numbers of males and females in a herd of dinosaurs.

    Femora from an exceptionally large population of coeval ornithomimosaurs yield evidence of sexual dimorphism in extinct theropod dinosaurs

    Romain Pintore, Raphaël Cornette ... Ronan Allain
    Consistent bimodal variations in the femoral morphology of various modern amniotes and a remarkably large herd of coeval fossil non-avian theropods evidences sexual dimorphism in dinosaurs.

    Metabolic consequences of various fruit-based diets in a generalist insect species

    Laure Olazcuaga, Raymonde Baltenweck ... Julien Foucaud
    Metabolomic analyses indicate that diet generalism may stem from a neutral metabolic response to different chemistries, rather than from an accumulation of specific adaptations.

    Endoparasitoid lifestyle promotes endogenization and domestication of dsDNA viruses

    Benjamin Guinet, David Lepetit ... Julien Varaldi
    The propensity to endogenize and domesticate dsDNA viruses depends on lifestyle in Hymenoptera.

    Antagonistic role of the BTB-zinc finger transcription factors Chinmo and Broad-Complex in the juvenile/pupal transition and in growth control

    Sílvia Chafino, Panagiotis Giannios ... Xavier Franch-Marro
    Stage identity and developmental progression in insects is controlled by sequential expression of temporal-specific transcription factors.

    Tradeoffs explain scaling, sex differences, and seasonal oscillations in the remarkable weapons of snapping shrimp (Alpheus spp.)

    Jason P Dinh, SN Patek
    Observational field analyses demonstrate that within a species, variation in animal weapon size corresponds to individual differences in the costs and benefits of weaponry.
