Reviewers in Biology propose SIRT1 functional reserve — the remaining operational flexibility of SIRT1-dependent responses under a defined stress load — as a more meaningful measure than static SIRT1 or NAD+ levels. Total cellular NAD+ obscures compartment-specific availability, and total SIRT1 obscures the accumulation of less functional v2 and v3 isoforms with age, which may account for the modest results of supplementation trials aimed at raising these molecules.
A hormone-free clitoral air-pulse device has launched in UK retail pharmacy with preliminary data linking sexual stimulation to menopausal symptom relief and increased vagal tone. In a 66-woman, four-week user study, 92.9% reported improvement in at least one of more than 34 possible symptoms, a threshold met without a control group. Separate observational work in 130 menopausal women associated regular sexual activity with higher heart rate variability, consistent with greater parasympathetic regulation.
Using mice with identical nuclear genomes but divergent mitochondrial DNA haplotypes, researchers found that mitochondrial genetic background alone alters baseline retinal electrophysiology and shapes how the retina remodels its bioenergetic machinery with age. Aging reduced Complex III and V abundance while increasing Complex IV, raised mitochondrial DNA damage, and elevated microglial STING expression, with inherited mtDNA variation modifying that neuroimmune response.
Better U and Evernow have launched a nationwide telehealth partnership combining menopause and hormone expertise with integrative psychiatry, addressing perimenopausal mood, sleep and cognitive complaints as hormonally driven rather than purely psychiatric. The model includes screened, off-label at-home ketamine for treatment-resistant depression or anxiety, though no outcome data has been published. The clinical rationale rests on estrogen's modulation of serotonin and dopamine and allopregnanolone's action at GABA receptors.
Researchers in Hong Kong applied and compared competing economic methods — including opportunity cost and replacement cost approaches — to quantify the monetary value of unpaid family caregiving for older adults. The choice of valuation method materially changes the estimated economic contribution of informal carers, with direct consequences for how aging societies budget for long-term care. Family caregiving represents a substantial but largely uncounted pillar of the elder care economy.
Analysis of postmenopausal women in China links reproductive history — including age at menarche, parity, and age at menopause — to the population burden of ischaemic heart disease, with the magnitude of that burden differing across socioeconomic strata. Women in lower socioeconomic groups carry a disproportionate share of reproductive factor-associated cardiovascular risk. The findings position reproductive history as an early, documentable marker of long-term cardiovascular trajectory rather than an isolated obstetric detail.
Function and Google Health have announced a partnership that will allow US users to import results from Function's 160-plus lab tests into the Google Health app this fall, pairing biochemical data with continuous wearable signals including resting heart rate, sleep architecture, heart rate variability and cardio load. The stated aim is to link daily behaviors to measurable biological markers across cardiovascular, metabolic, hormonal and nutrient domains. Google Health Coach will draw on personal health records to tailor guidance, with the caveat that AI-generated coaching may be inaccurate or incomplete.
A harmonised analysis of multiple longitudinal cohorts across the USA, England, continental Europe, China, and Japan found that stronger social connection was consistently associated with higher intrinsic capacity at baseline, with the largest associations in cognitive and psychological domains. Social connection at baseline did not, however, predict the rate of intrinsic capacity decline over follow-up. The cross-cultural consistency of the baseline association strengthens the case for treating social connection as a measurable component of functional ageing rather than a peripheral lifestyle variable.
A review of social engagement programming delivered by Area Agencies on Aging examines how the primary local infrastructure for US aging services addresses social isolation and loneliness. Both conditions are established public health concerns in later life, linked to elevated morbidity and premature mortality, placing community-level program design within the scope of modifiable longevity risk.
Research in the Journal of Applied Gerontology examines how community-level economic distress shapes physical and mental health outcomes among grandparents raising grandchildren, a population already exposed to elevated financial strain. The findings position neighborhood context as an independent influence on caregiver health rather than a background variable, with implications for how chronic stress exposure accumulates across later life.
An analysis of national U.S. nursing home data from 2013 to 2023 examined whether the well-documented decline in antipsychotic prescribing was distributed evenly across facilities. Aggregate improvement appears to coexist with a widening separation between the highest- and lowest-performing facilities, a divergence associated with structural vulnerability and the pandemic period. For older adults, exposure to these medications carries consequences for cognition, mobility, and mortality risk that extend well beyond the prescribing decision itself.
This Lancet Healthy Longevity commentary examines whether improvements in intrinsic capacity — the composite of vitality, locomotion, cognition, psychological, and sensory function that underpins WHO's healthy ageing model — are shared equally across socioeconomic strata and successive birth cohorts. The analysis indicates that population-level gains in late-life function coexist with persistent socioeconomic gradients, meaning later-born generations do not benefit uniformly. Functional ability in older age is framed as the product of intrinsic capacity interacting with environment, placing structural conditions alongside individual physiology as determinants of healthspan.
