    RNA-programmed genome editing in human cells

    Martin Jinek et al.
    A bacterial protein can be programmed with short RNA molecules to stimulate genome editing at specific sites in human cells.

    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.

    Changing the responses of cortical neurons from sub- to suprathreshold using single spikes in vivo

    Verena Pawlak et al.
    Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

    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.

    Cdc48/p97 promotes degradation of aberrant nascent polypeptides bound to the ribosome

    Rati Verma et al.
    The enzyme that collaborates with ubiquitin ligases to promote the release of defective polypeptides from stalled ribosomes in a process named ribosome-associated degradations has been identified as the ATPase Cdc48.

    A virus responds instantly to the presence of the vector on the host and forms transmission morphs

    Alexandre Martinière et al.
    Cauliflower mosaic virus reacts immediately when aphids feed on the host plant, and this boosts its chances of being taken up and transmitted by the insects to a new plant.

    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.

    Dual functions of TAF7L in adipocyte differentiation

    Haiying Zhou et al.
    A combination of cellular, biochemical, genetic and genomic techniques have revealed a new molecular player in the production of fat cells in mice, which could improve our understanding of obesity.

    A novel GTP-binding protein–adaptor protein complex responsible for export of Vangl2 from the trans Golgi network

    Yusong Guo et al.
    The ability of epithelial cells to distinguish between domains on opposing cell surfaces within a tissue, a property known as planar cell polarity, relies on proteins and protein complexes directing the traffic of signaling proteins to specific locations on the cell surface membrane.

    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.
