    The human origin recognition complex is essential for pre-RC assembly, mitosis, and maintenance of nuclear structure

    Hsiang-Chen Chou, Kuhulika Bhalla ... Bruce Stillman
    The initiation of human genome replication requires the six-subunit origin recognition complex (ORC) and CDC6, with ORC playing additional roles during mitosis and in organization of the cell nucleus.

    Structure of the active form of human origin recognition complex and its ATPase motor module

    Ante Tocilj, Kin Fan On ... Leemor Joshua-Tor
    The human Origin Replication Complex is shaped as a shallow corkscrew in a classic AAA+ organization reminiscent of clamp loader complexes with highly controlled ATPase activity as exemplified by Meier-Gorlin syndrome mutations.

    Cascade of neural processing orchestrates cognitive control in human frontal cortex

    Hanlin Tang, Hsiang-Yu Yu ... Gabriel Kreiman
    A dynamic and hierarchical sequence of steps in human frontal cortex orchestrates cognitive control.
    1. Neuroscience

    Microstructural organization of human insula is linked to its macrofunctional circuitry and predicts cognitive control

    Vinod Menon, Guillermo Gallardo ... Demian Wassermann
    In vivo quantitative analysis of multi-shell diffusion MRI reveals novel insights into microstructure of human insular cortex and its functional circuits associated with the salience network and cognitive control.

    Sleep-dependent upscaled excitability, saturated neuroplasticity, and modulated cognition in the human brain

    Mohammad Ali Salehinejad, Elham Ghanavati ... Michael A Nitsche
    The sleep-deprived brain in humans undergoes upscaled intracortical excitability which diminishes induction of LTP-like plasticity via transcranial electrical stimulation while converting the LTD-like to LTP-like plasticity and these physiological changes couple with impaired learning, memory, and attention at behavioral level.

    Structural insights into the assembly and polyA signal recognition mechanism of the human CPSF complex

    Marcello Clerici, Marco Faini ... Martin Jinek
    Structural, biochemical, and proteomic analyses of a four-subunit core module of the cleavage and polyadenylation specificity factor complex reveal its molecular architecture and specific determinants of polyadenylation signal recognition in human mRNAs.
    1. Immunology and Inflammation

    The structure of a LAIR1-containing human antibody reveals a novel mechanism of antigen recognition

    Fu-Lien Hsieh, Matthew K Higgins
    The structure of a human antibody in which the variable loops position a human protein LAIR1 for antigen recognition, reveals a novel and indirect mode of antibody function.

    Ligand recognition and gating mechanism through three ligand-binding sites of human TRPM2 channel

    Yihe Huang, Becca Roth ... Juan Du
    High-resolution structures of human TRPM2 in different functional states provided the mechanism underlying ligand recognition, channel activation and inhibition.
    1. Neuroscience

    Functional specialization within the inferior parietal lobes across cognitive domains

    Ole Numssen, Danilo Bzdok, Gesa Hartwigsen
    Data-driven and effective connectivity analyses reveal patterns of functional specialization, common mechanisms, and brain-wide interaction profiles within the human inferior parietal lobes for multiple functional domains.
    1. Neuroscience

    Songbirds can learn flexible contextual control over syllable sequencing

    Lena Veit, Lucas Y Tian ... Michael S Brainard
    Songbirds can use arbitrary visual cues to immediately, flexibly and adaptively control syntax of learned song vocalizations in a manner that parallels human cognitive control over syllable sequencing in speech.
