    Resolving homology in the face of shifting germ layer origins: Lessons from a major skull vault boundary

    Camilla S Teng et al.
    Homology of vertebrate skull structures should be based on evolutionary continuity and an appreciation of germ layer origins and inductive signaling in the embryonic head.

    Species specific differences in use of ANP32 proteins by influenza A virus

    Jason S Long et al.
    Chicken ANP32A, and not chicken ANP32B, supports influenza polymerase activity and thus editing of this single gene may generate chickens that are resilient to influenza virus infection.

    Developmental 'awakening' of primary motor cortex to the sensory consequences of movement

    James C Dooley, Mark S Blumberg
    Early in development, before neurons in primary motor cortex are involved in motor control, they undergo a rapid transition in how they process sensory information following sleep and wake movements.

    No general relationship between mass and temperature in endothermic species

    Kristina Riemer et al.
    Data analysis of a large number of species indicates that a negative temperature-mass relationship is not common among species, which has been an ecological assumption for over a century.

    Shaping of inner ear sensory organs through antagonistic interactions between Notch signalling and Lmx1a

    Zoe F Mann et al.
    A dynamic confrontation between Notch signalling and the transcription factor Lmx1a at the borders of the developing inner ear sensory patches regulates their segregation and the positioning of their boundaries.

    Evolution-guided functional analyses reveal diverse antiviral specificities encoded by IFIT1 genes in mammals

    Matthew D Daugherty et al.
    Evolutionary innovation and turnover in the IFIT1 antiviral gene family has led to diverse repertoires of antiviral specificity across mammals.

    Dual control of pcdh8l/PCNS expression and function in Xenopus laevis neural crest cells by adam13/33 via the transcription factors tfap2α and arid3a

    Vikram Khedgikar et al.
    The regulation of tfap2α expression by adam13 is essential during cranial neural crest cell migration in Xenopus laevis.

    TP53 copy number expansion is associated with the evolution of increased body size and an enhanced DNA damage response in elephants

    Michael Sulak et al.
    Elephants escaped enhanced cancer susceptibility by evolving more master tumor suppressor genes.

    Evolution of gene dosage on the Z-chromosome of schistosome parasites

    Marion A L Picard et al.
    An analysis of gene dosage at the DNA, RNA and protein level yields new insights into the early stages of Z-chromosome dosage compensation in schistosome parasites.

    Characterization of a Toxoplasma effector uncovers an alternative GSK3/β-catenin-regulatory pathway of inflammation

    Huan He et al.
    A genetic screen in combination with biochemical approaches reveal hijacking of the host β-catenin destruction complex by the parasite T. gondii to reprogram immune gene expression.
