Accelerated global population aging challenges conventional economic growth paths. Yet, the mechanisms underlying the transition from the age-based demographic dividend, derived from a favorable age support ratio (ASR), to a skill-based dividend, driven by human capital accumulation, remain insufficiently understood. Using population census data for 336 Chinese cities from 2000 to 2020, we develop a task-based skill ratio (TSR) index to quantify the skill composition of local labor markets,...

Human longevity arises from complex genetic and environmental interactions, yet the genetic basis of survival to extreme old age remains underexplored in Asian populations. We performed genome-wide association studies (GWAS) in a Taiwanese cohort, defining survival thresholds at ≥ 85, ≥ 90, and ≥ 95 years, and validated significant loci in an independent cohort. Multiple loci, including ZNF806, NUAK1, TANC1, SLC22A3, PTPRD, and PCSK2, were associated with longevity, of which 14 replicated with...

CONCLUSION: Higher optimism was associated with a lower incidence of dementia. These findings suggest a potential value of optimism in supporting healthy aging, which could be considered in future research on dementia prevention initiatives.

CONCLUSION: Our findings demonstrated OAβT as a reflection of systemic changes linked to early AD pathology. Moreover, the influence of medications and systemic aging on OAβT values pointed to the potential avenues for intervention and emphasized the importance of considering systemic factors in AD pathogenesis and treatment.
