    Homology sensing via non-linear amplification of sequence-dependent pausing by RecQ helicase

    Yeonee Seol et al.
    The rate of DNA unwinding by RecQ helicases is dramatically modulated by the DNA duplex stability in a geometry-dependent manner, providing an intrinsic mechanism for suppressing illegitimate recombination.

    Molecular insights into RNA and DNA helicase evolution from the determinants of specificity for a DEAD-box RNA helicase

    Anna L Mallam et al.
    The core domains of an RNA helicase interact with a wide variety of NTPs and nucleic acids suggesting how related enzymes may have evolved to have diverse functions.

    Action of CMG with strand-specific DNA blocks supports an internal unwinding mode for the eukaryotic replicative helicase

    Lance Langston, Mike O’Donnell
    The CMG complex, the replicative helicase in eukaryotes, uses a different mechanism from bacterial and viral helicases by engaging both strands of parental DNA with substantial force and unwinding the duplex within the central channel of CMG.

    Direct single molecule measurement of TCR triggering by agonist pMHC in living primary T cells

    Geoff P O'Donoghue et al.
    Quantitative observations of single-molecule binding between antigen and T cell receptor (TCR) in living primary T cells reveals unbinding kinetics, stoichiometry and signaling molecule recruitment, providing insights into the mechanisms of antigen recognition by the immune system.

    Structural basis of nucleic-acid recognition and double-strand unwinding by the essential neuronal protein Pur-alpha

    Janine Weber et al.
    The crystal structure of Pur-alpha in complex with DNA reveals its molecular mechanisms of nucleic-acid binding and unwinding, allowing for a better understanding of its essential role in neurons.

  1. Living Science: Words without meaning

    Eve Marder
    Many of the words used by scientists when reviewing manuscripts, job candidates and grant applications – words such as incremental, novelty, mechanism, descriptive and impact – have lost their meaning.
