    Proteostasis collapse, a hallmark of aging, hinders the chaperone-Start network and arrests cells in G1

    David F Moreno et al.
    Cells accumulate damaged proteins during aging and, by compromising the function of chaperones in folding newly synthesized G1 cyclins, proteostasis breakdown inhibits cell-cycle entry and drives yeast cells into senescence.

    Longitudinal imaging of Caenorhabditis elegans in a microfabricated device reveals variation in behavioral decline during aging

    Matthew A Churgin et al.
    The WorMotel, a novel microfabricated device for automated longitudinal imaging of aging in large numbers of Caenorhabditis elegans, reveals that long and short lived strains vary in their behavioral decline during aging in a similar way to the long and short lived individuals in a wild type population.

    POWERDRESS interacts with HISTONE DEACETYLASE 9 to promote aging in Arabidopsis

    Xiangsong Chen et al.
    Genetic and biochemical studies reveal how a histone deacetylase acts together with other chromatin regulators to promote the onset of plant aging.

    Elevating acetyl-CoA levels reduces aspects of brain aging

    Antonio Currais et al.
    A novel neuroprotective pathway that enhances acetyl-CoA metabolism via inhibition of acetyl-CoA carboxylase 1 may prevent the contribution of the aging process in the brain to Alzheimer's disease.

    DNA damage checkpoint activation impairs chromatin homeostasis and promotes mitotic catastrophe during aging

    Matthew M Crane et al.
    Activation of a DNA-damage cell cycle checkpoint during aging causes genome instability and senescence in yeast mother cells.

    Changes of mitochondrial ultrastructure and function during ageing in mice and Drosophila

    Tobias Brandt et al.
    Respiratory activity and inner membrane organisation of mitochondria from Drosophila melanogaster break down during ageing, but mouse heart mitochondria appear to be protected against age-related damage.

    Time line of redox events in aging postmitotic cells

    Nicolas Brandes et al.
    A sudden fall in the levels of the coenzyme NADPH within cells could have a central role in the process of aging.

    Mother-daughter asymmetry of pH underlies aging and rejuvenation in yeast

    Kiersten A Henderson et al.
    Protons are pumped out of mother cells by a protein that accumulates over time and this leads to cellular aging, but this protein is largely absent from daughter cells, which mediates rejuvenation.

    Cortical tau deposition follows patterns of entorhinal functional connectivity in aging

    Jenna N Adams et al.
    Tau deposition in the aging brain follows patterns of functional connectivity that correspond to specific neural memory networks, and this relationship is strengthened in the presence of amyloid-β.

    PUMILIO hyperactivity drives premature aging of Norad-deficient mice

    Florian Kopp et al.
    Long noncoding RNA Norad performs an essential function in mammalian physiology by inhibiting the activity of PUMILIO RNA binding proteins, thereby suppressing a multi-system degenerative phenotype resembling premature aging.
