    Structure and activation mechanism of the BBSome membrane protein trafficking complex

    Sandeep K Singh et al.
    Two cryo-EM structures of the mammalian BBSome show how the BBSome is recruited to membranes and activated by the GTPase ARL6 prior to binding transmembrane proteins.

    Purinergic signaling in cochlear supporting cells reduces hair cell excitability by increasing the extracellular space

    Travis A Babola et al.
    Supporting cells in the cochlea change their shape in response to purinergic receptor activation, which influences hair cell excitability by altering potassium redistribution in the extracellular space.

    Noninvasive quantification of axon radii using diffusion MRI

    Jelle Veraart et al.
    Cell-specific architectural properties such as the axon diameter of the white matter of the human brain can be quantified accurately and non-invasively using diffusion magnetic resonance imaging.

    Mechanisms underlying the response of mouse cortical networks to optogenetic manipulation

    Alexandre Mahrach et al.
    Combining experimental and theoretical approaches reveals the interplay between optogenetic manipulation and recurrent interactions in mouse cortex.

    Distinct cytoskeletal proteins define zones of enhanced cell wall synthesis in Helicobacter pylori

    Jennifer A Taylor et al.
    The helical bacterium Helicobacter pylori patterns cell wall synthesis using two distinct cytoskeletal proteins, CcmA and MreB, to achieve its characteristic shape.

    Body height in young adult men and risk of dementia later in adult life

    Terese Sara Høj Jørgensen et al.
    Taller body height in young adulthood, as marker of early-life environment, is associated with lower risk of dementia diagnosis independently of cognitive reserve and family factors shared among brothers.

    Using subthreshold events to characterize the functional architecture of the electrically coupled inferior olive network

    Yaara Lefler et al.
    Non-synaptic electrical events recorded simultaneously from pairs of neurons in the inferior olive nucleus enables accurate estimation of the size and of the clustered organization of the electrically coupled network.

    Origin of the mechanism of phenotypic plasticity in satyrid butterfly eyespots

    Shivam Bhardwaj et al.
    A gradual, step-wise, physiological/molecular response of eyespot size to temperature is a likely adaptation to seasonal variation experienced in the habitat of Bicyclusanynana butterflies.

    Pan-mammalian analysis of molecular constraints underlying extended lifespan

    Amanda Kowalczyk et al.
    Cancer control, DNA repair, and immunity are key functionalities underlying the evolution of extended lifespan in mammals.

    Longitudinal trajectories, correlations and mortality associations of nine biological ages across 20-years follow-up

    Xia Li et al.
    Biological ages have the potential to provide aging-related information beyond chronological age and can be predictive of mortality independently of both chronological age and different types of biological ages.
