    Crystallographic observation of nonenzymatic RNA primer extension

    Wen Zhang et al.
    Time resolved crystal structures reveal the binding of activated monomers to the template, followed by generation of the imidazolium-bridged dinucleotide intermediate, and finally formation of a phosphodiester bond between the primer and the adjacent monomer.

    The Natural History of Model Organisms: Insights into the evolution of social systems and species from baboon studies

    Julia Fischer et al.
    Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

    Science Forum: Viral factors in influenza pandemic risk assessment

    Marc Lipsitch et al.
    We identify key strengths and limitations in use of viral genotyping and phenotyping to estimate pandemic risk from influenza A viruses, focusing on 3 traits, hemagglutinin binding specificity, hemagglutinin pH of activation, and polymerase complex efficiency.

    Protein-mediated RNA folding governs sequence-specific interactions between rotavirus genome segments

    Alexander Borodavka et al.
    In rotaviruses, the selective packaging of eleven distinct genomic RNA segments requires virus-encoded protein NSP2 to alter the RNA structures, facilitating their interactions with each other.

    Tandem hnRNP A1 RNA recognition motifs act in concert to repress the splicing of survival motor neuron exon 7

    Irene Beusch et al.
    The structural model of hnRNP A1 shows that it can bind with both RRMs to RNA, which is shown to be relevant for the SMN2 exon 7 splicing mechanism in vivo.
