    Drift and termination of spiral waves in optogenetically modified cardiac tissue at sub-threshold illumination

    Sayedeh Hussaini et al.
    Excitability gradients in heart tissue, imposed by structured sub-threshold optogenetic stimulation, induce drift and termination of spiral waves, thus providing an explanation for successful optogenetic defibrillation in small animal hearts.

    Integrating influenza antigenic dynamics with molecular evolution

    Trevor Bedford et al.
    Combined antigenic and genetic analysis shows that different strains of the human influenza virus display dramatically different rates of antigenic drift, and that these differences have a significant impact on the number of new infections in each flu season.

    Asynchrony between virus diversity and antibody selection limits influenza virus evolution

    Dylan H Morris et al.
    Despite the virus' error prone polymerase, influenza virus antigenic evolution is rare, even in previously immune hosts, virus replication occurs before producing new antibodies.

    The global antigenic diversity of swine influenza A viruses

    Nicola S Lewis et al.
    Swine populations worldwide are sporadically infected by influenza viruses from humans and birds leading to geographically heterogeneous swine influenza virus populations that pose epizootic and pandemic threats.

    Viral dark matter and virus–host interactions resolved from publicly available microbial genomes

    Simon Roux et al.
    From public microbial genomes, VirSorter revealed 12,498 viral genome sequences that expand the map of the global virosphere and whose analyses improve understanding of viral taxonomy, evolution and virus-host interactions.

    Conjunction of factors triggering waves of seasonal influenza

    Ishanu Chattopadhyay et al.
    Three complementary computational approaches reveal a set of putative causes of initiation of pan-USA waves of influenza.

    Cortex-wide BOLD fMRI activity reflects locally-recorded slow oscillation-associated calcium waves

    Miriam Schwalm et al.
    Locally recorded calcium events related to slow wave activity show a global cortical fMRI BOLD correlate, establishing a direct relation between a basic neurophysiological signal and the macroscopic perspective of pre-clinical fMRI.

    Frontal eye field and caudate neurons make different contributions to reward-biased perceptual decisions

    Yunshu Fan et al.
    In monkeys making decisions that balance noisy evidence and reward expectation, frontal cortical and caudate activity reflect different computational components that are related to the monkeys' strategy.

    Nuclear crowding and nonlinear diffusion during interkinetic nuclear migration in the zebrafish retina

    Afnan Azizi et al.
    The evolving spatial distribution of nuclei between apical and basal surfaces of the developing retinal neuroepithelium is quantitatively described by a nonlinear diffusion equation accounting for crowding within the tissue.

    Stochastic processes constrain the within and between host evolution of influenza virus

    John T McCrone et al.
    An analysis of influenza viruses from naturally infected people suggests a tight transmission bottleneck and little positive selection within hosts.
