    Architecture and dynamics of the autophagic phosphatidylinositol 3-kinase complex

    Sulochanadevi Baskaran et al.
    The first three-dimensional structure of the PI3KC3 complex I, which is involved in autophagy, provides a framework for understanding the allosteric regulation of lipid kinase activity.
    1. Neuroscience

    Unsupervised discovery of temporal sequences in high-dimensional datasets, with applications to neuroscience

    Emily L Mackevicius et al.
    Building on simple unsupervised matrix factorization techniques, the seqNMF algorithm successfully recovers neural sequences in a wide range of simulated and real datasets.

    Identifying prostate cancer and its clinical risk in asymptomatic men using machine learning of high dimensional peripheral blood flow cytometric natural killer cell subset phenotyping data

    Simon P Hood et al.
    Diagnosing the presence and clinical significance of prostate cancer can be achieved using AI-based analysis of peripheral blood natural killer (NK) cell subset profiles.

    Velocity coupling of grid cell modules enables stable embedding of a low dimensional variable in a high dimensional neural attractor

    Noga Mosheiff, Yoram Burak
    The neural representation of position in the medial entorhinal cortex may be stabilized by synaptic connectivity across modules, which enforces coherent updates in their states.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann et al.
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.
    1. Neuroscience

    Cortical state transitions and stimulus response evolve along stiff and sloppy parameter dimensions, respectively

    Adrian Ponce-Alvarez et al.
    Neurons differ in their impact on collective cortical activity, with sensitive neurons forming a stable topological core, implicated in cortical-state transitions, while peripheral insensitive neurons are more responsive to stimuli.

    FluoEM, virtual labeling of axons in three-dimensional electron microscopy data for long-range connectomics

    Florian Drawitsch et al.
    Methodology to annotate the multiple origins of axonal projections in dense electron microscopy data of mammalian nervous tissue without the need of chemical label conversion is reported.

    Allosteric mechanism of the V. vulnificus adenine riboswitch resolved by four-dimensional chemical mapping

    Siqi Tian et al.
    A new biochemical method tests whether or not the pre-existing RNA structural correlations couple small molecule binding to gene expression in a paradigmatic riboswitch.

    Probable nature of higher-dimensional symmetries underlying mammalian grid-cell activity patterns

    Alexander Mathis et al.
    Mathematical analysis confirms that hexagonal patterns of neuronal activity are the most efficient means for the brain to represent 2D space, and predicts that activity patterns resembling densely packed lattices are optimal for representing 3D space.
