    Adaptive evolution of nontransitive fitness in yeast

    Sean W Buskirk et al.
    A series of selective events, each improving fitness relative to an immediate predecessor, can result in organisms that are less fit compared to a distant ancestor.

    Experimental Evolution: Failure to progress

    Duncan Greig, Jasmine Ono
    Experiments on yeast cells that are hosts to a killer virus confirm that natural selection can sometimes reduce fitness.

    Differential cell autonomous responses determine the outcome of coxsackievirus infections in murine pancreatic α and β cells

    Laura Marroqui et al.
    Pancreatic α and β cells have different cell autonomous signatures; this explains why α but not β cells can clear infections by potentially diabetogenic viruses.

    Updates to the zoonotic niche map of Ebola virus disease in Africa

    David M Pigott et al.
    Building on previous work (Pigott et al. 2014), estimates of areas of potential transmission of Ebola virus are revised and updated to provide a contemporary map for use by researchers and policymakers.

    The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea

    Christoph M Deeg et al.
    Bodo saltans virus defines the most abundant giant viruses in the ocean and highlights the genomic plasticity, rooted in evolutionary arms races, that gave rise to giant viruses.

    Parvovirus minute virus of mice interacts with sites of cellular DNA damage to establish and amplify its lytic infection

    Kinjal Majumder et al.
    Development of a generally adaptable conformational capture assay for use in-trans identifies the specific direct interaction sites between the parvovirus minute virus of mice and the cellular genome during infection as sites of cellular DNA damage.

    Structural basis of HIV-1 Vpu-mediated BST2 antagonism via hijacking of the clathrin adaptor protein complex 1

    Xiaofei Jia et al.
    HIV-1 viral protein u (Vpu) can stimulate novel versions of canonical interactions with the clathrin adaptor AP1 to counteract the host antiviral protein BST2.

    Control of immune ligands by members of a cytomegalovirus gene expansion suppresses natural killer cell activation

    Ceri A Fielding et al.
    The human cytomegalovirus US12 gene family work co-operatively to degrade large numbers of immune ligands and prevent recognition by natural killer cells.

    A new topology of the HK97-like fold revealed in Bordetella bacteriophage by cryoEM at 3.5 Å resolution

    Xing Zhang et al.
    Cryo electron microscopy and structure-based mutagenesis reveal that the bacteriophage BPP-1 contains two of the three major recognized viral folds, one of which exhibits a new topology.
