    Molecular conservation of marsupial and eutherian placentation and lactation

    Michael W Guernsey et al.
    The short-lived tammar wallaby placenta expresses genes resembling eutherian placentas, establishing marsupials as "placental mammals", further, dynamic lactation allows marsupials to compensate for short placentation by expressing key placental genes in the mammary gland.

    Reproduction: What is a placental mammal anyway?

    Patrick Abbot, John A Capra
    Many developmental functions in marsupials and eutherian mammals are accomplished by different tissues, but similar genes.

    Contagious Cancers: A ‘devil’ of a problem

    Victoria L Hansen, Robert D Miller
    The discovery of a second facial tumor disease in the Tasmanian devil has provided insights into the emergence of contagious cancers.

    The brown adipocyte protein CIDEA promotes lipid droplet fusion via a phosphatidic acid-binding amphipathic helix

    David Barneda et al.
    An interaction between the brown fat protein CIDEA and the phospholipid phosphatidic acid is vital for the expansion of intracellular lipid droplets for energy storage.

    Retinal oxygen supply shaped the functional evolution of the vertebrate eye

    Christian Damsgaard et al.
    Multiple respiratory and vascular mechanisms have recurrently evolved across the vertebrates to alleviate the oxygen diffusion limitations inherent to the morphology of the retina.

    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.

    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.

    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.

    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.

    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.
