    Ribosome structures to near-atomic resolution from thirty thousand cryo-EM particles

    Xiao-chen Bai et al.
    A combination of direct-electron detectors and statistical movie processing allows ribosome cryo-EM structures to be determined to resolutions that were previously only attainable by X-ray crystallography.

    Enabling X-ray free electron laser crystallography for challenging biological systems from a limited number of crystals

    Monarin Uervirojnangkoorn et al.
    Post-refinement methods enable the use of X-ray free electron lasers for biological crystallography of systems in which sample quantity is a limitation.

    Ultra-Rapid serial visual presentation reveals dynamics of feedforward and feedback processes in the ventral visual pathway

    Yalda Mohsenzadeh et al.
    Reducing visibility with higher image presentation rates increases recurrent processing demands along the visual processing pathway to resolve object recognition.
    1. Neuroscience

    Variance predicts salience in central sensory processing

    Ann M Hermundstad et al.
    Psychophysical measures of human sensitivity to visual patterns reveal that the brain preferentially processes those features of stimuli that are more variable in the natural world.

    Visual processing of informative multipoint correlations arises primarily in V2

    Yunguo Yu et al.
    Building on recent findings that central sensory processing allocates resources according to the informativeness of statistical features (Hermundstad et al., 2014), we identify visual area V2 as the site of the relevant computations for local image statistics, thus providing a common underpinning for diverse aspects of its neuronal selectivity.

    Low cost, high performance processing of single particle cryo-electron microscopy data in the cloud

    Michael A Cianfrocco, Andres E Leschziner
    A freely available software environment on Amazon's cloud computing network makes processing of cryo-EM data accessible and affordable.
    1. Neuroscience

    Asymmetric ON-OFF processing of visual motion cancels variability induced by the structure of natural scenes

    Juyue Chen et al.
    The fruit fly estimates visual motion by incorporating ON-OFF asymmetric processing that only improves performance when stimuli have light-dark asymmetries matched to natural scenes.
    1. Neuroscience

    DeepPoseKit, a software toolkit for fast and robust animal pose estimation using deep learning

    Jacob M Graving et al.
    A new deep-learning software toolkit with general-purpose methods for quickly and reliably measuring the full body posture of animals directly from images or videos without physical markers.
