    Late-life restoration of mitochondrial function reverses cardiac dysfunction in old mice

    Ying Ann Chiao et al.
    Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.

    Age-related changes in polycomb gene regulation disrupt lineage fidelity in intestinal stem cells

    Helen M Tauc et al.
    Global, multi-angled genetic analyses identified an age-associated loss of stem cell lineage fidelity that was linked to changes in polycomb regulation in the Drosophila intestinal epithelium.

    Maintenance of age in human neurons generated by microRNA-based neuronal conversion of fibroblasts

    Christine J Huh et al.
    MicroRNA-based direct conversion of human fibroblasts to neurons is applicable to fibroblasts from donors ranging in age from neonatal to centenarian, allowing the generation of neurons that maintain the age-associated signatures of the starting fibroblasts.

    Castration delays epigenetic aging and feminizes DNA methylation at androgen-regulated loci

    Victoria J Sugrue et al.
    Epigenetic clocks are an accurate measure of biological aging and 'tick' slower in male sheep that are castrated.

    A whole lifespan mouse multi-tissue DNA methylation clock

    Margarita V Meer et al.
    A robust mouse multi-tissue age predictor is presented that can be used to assess the DNA methylation age of mouse tissues and test the effects of longevity interventions.

    Genetic and environmental influences on adult human height across birth cohorts from 1886 to 1994

    Aline Jelenkovic et al.
    Genetic variance of adult human height shows a generally increasing trend across the birth-year cohorts but heritability estimates do not present any clear pattern of secular changes over a century.

    Progerin reduces LAP2α-telomere association in Hutchinson-Gilford progeria

    Alexandre Chojnowski et al.
    Expression of the lamina-associated polypeptide α (LAP2α) prevents premature cellular ageing caused by expression of progerin in Hutchinson-Gilford progeria syndrome.

    Personality links with lifespan in chimpanzees

    Drew M Altschul et al.
    Among captive chimpanzees, higher agreeableness males and higher openness females survive longer.

    Whole-genome sequencing analysis of semi-supercentenarians

    Paolo Garagnani et al.
    Genetic variants located in DNA repair genes and a reduced burden of somatic mutations protect the oldest living persons from age-related diseases, allowing an healthy aging phenotype.

    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.
