    Population structuring of multi-copy, antigen-encoding genes in Plasmodium falciparum

    Yael Artzy-Randrup et al.
    Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

    KDM2B links the Polycomb Repressive Complex 1 (PRC1) to recognition of CpG islands

    Anca M Farcas et al.
    A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.

    DNA-PK is a DNA sensor for IRF-3-dependent innate immunity

    Brian J Ferguson et al.
    Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.

    Meiosis I chromosome segregation is established through regulation of microtubule–kinetochore interactions

    Matthew P Miller et al.
    Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

    Modelling dynamics in protein crystal structures by ensemble refinement

    B Tom Burnley et al.
    A combination of molecular dynamics simulations and X-ray diffraction data has been used to construct more realistic models of proteins and to provide new insights into their interactions with other proteins and biomolecules.

    rsEGFP2 enables fast RESOLFT nanoscopy of living cells

    Tim Grotjohann et al.
    The discovery of a fluorescent protein that can be rapidly switched between long-lived ‘on’ and ‘off’ states will lead to a new generation of super-resolution imaging experiments on living cells.

    Myosin motors fragment and compact membrane-bound actin filaments

    Sven K Vogel et al.
    A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.

    Quantification of gait parameters in freely walking wild type and sensory deprived Drosophila melanogaster

    César S Mendes et al.
    Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

    NOVA-dependent regulation of cryptic NMD exons controls synaptic protein levels after seizure

    Taesun Eom et al.
    The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.

    Strong inter-population cooperation leads to partner intermixing in microbial communities

    Babak Momeni et al.
    Simulations and experiments on systems containing two different populations of microorganisms show that interactions that benefit at least one of the populations can lead to communities with stable compositions, and that strong cooperation between two populations can lead to communities in which both populations are mixed together.
