    • In our aging global population and with no effective treatments, the cognitive impairments associated with Alzheimer’s disease represent a major healthcare problem. A recent study in Nature Aging highlights intermittent fasting as a potential way to decrease the progression of Alzheimer’s disease in mice through changes to the gut microbiota.

    • Aging is associated with an accumulation of myeloid-biased hematopoietic stem cells with reduced regenerative potential, but the underlying mechanisms remain unclear. A study by Wendorff et al. demonstrates that inactivation of a single epigenetic regulator — the plant homeodomain factor 6 (PHF6) — transcriptionally and functionally rejuvenates mouse aged hematopoietic stem cells.

    • On 27 and 28 June 2022, the UK SPINE network (www.kespine.org.uk) held an in-person conference focusing on how new medicines could contribute to improving healthspan (healthy life years). The event facilitated knowledge exchange within the broader geroscience community by bringing together researchers and stakeholders from multiple sectors, including industry, academia, entrepreneurs, small-to-medium-sized enterprises, regulators, patients and carers, investors and policy makers.

    • We used data from the Longitudinal Aging Study in India (LASI) to provide up-to-date epidemiological estimates of the prevalence of vision impairment among the Indian population. We find that older adults, and particularly women, marginalized groups and those from lower socioeconomic strata, had a higher prevalence of visual impairment.

      Research Briefing
    • Our longitudinal study comparing the skin, gut and oral microbiomes of community-dwelling older adults and nursing home residents showed striking changes known to be linked to antibiotic resistance and disease risk. Such shifts were associated with frailty, not chronological age, and were most pronounced in the skin, the primary reservoir for infection risk.

  • The US National Academy of Medicine (NAM)’s first global grand challenge is dedicated to healthy longevity. We summarize the NAM’s Global Roadmap for Healthy Longevity, highlighting evidence that societies can benefit from untapped human, social and economic capital through investments throughout the life course.

  • In the age of rapid technological advance there are myths about older adults’ difficulties in using technology. Here I will debunk two common myths: first, the idea that age-related functional decline is entirely responsible; and second, the notion that everyone will be technologically adept once today’s older adults are gone.

  • The successful adoption and use of technology products and services for older adults remain limited. Although technological developments promise improved quality of life for older adults, ageism and access gaps impede their use. Implications and recommendations the design and distribution of new technologies for aging in place are discussed.
