    Emergence and diversification of a host-parasite RNA ecosystem through Darwinian evolution

    Taro Furubayashi et al.
    In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

    Kv2.1 mediates spatial and functional coupling of L-type calcium channels and ryanodine receptors in mammalian neurons

    Nicholas C Vierra et al.
    A potassium channel, as a nonconducting function, organizes compartmentalized neuronal calcium signaling microdomains via structural and functional coupling of plasma membrane and endoplasmic reticulum calcium channels.

    A regulatory microRNA network controls endothelial cell phenotypic switch during sprouting angiogenesis

    Stefania Rosano et al.
    Coordinated microRNAs activity induced by VEGF represses cell proliferation and favors cell migration at the onset of sprouting angiogenesis in endothelial cells.

    Incomplete inhibition of HIV infection results in more HIV infected lymph node cells by reducing cell death

    Laurelle Jackson et al.
    Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.

    Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

    Peter C Petersen, Rune W Berg
    Neuronal participation in generation of motor patterns in the spinal circuits is lognormal, which is an indication of a rich diversity of activity within the mean-driven as well as the fluctuation-driven regimes.

    Three dimensional reconstruction of energy stores for jumping in planthoppers and froghoppers from confocal laser scanning microscopy

    Igor Siwanowicz, Malcolm Burrows
    Three dimensional reconstructions of the mechanical energy stores of jumping insects reveal how the miniaturized components interact and function.

    Lis1 regulates dynein by sterically blocking its mechanochemical cycle

    Katerina Toropova et al.
    Structural and functional studies reveal how a ubiquitous regulator of dynein keeps the microtubule-based motor in a persistent track-bound state.

    Microsaccadic sampling of moving image information provides Drosophila hyperacute vision

    Mikko Juusola et al.
    New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

    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.
