In the context of rapid global aging, the importance of age-friendly community environments for promoting healthy aging and "aging in place" continues to increase. Using data from the 2011-2020 China Health and Retirement Longitudinal Study, this study investigated the impact of an age-friendly community environment on the age trajectories of late-life long-term care (LTC) dependency among older Chinese adults aged 60+ years. Age-friendly community environments were defined according to three levels (poor, moderate, or good) based on the World Health Organization's age-friendly city and community framework, and LTC dependency was classified as level 1 (high), level 2 (medium), or level 3 (low) according to activities of daily living and instrumental activities of daily living scores.

Article Synopsis
  • Therapsids were key players in ancient ecosystems and evolved into mammals during the early Mesozoic, but their origins are not well understood.
  • A newly discovered partial skeleton of a gorgonopsian from Mallorca is possibly the oldest known therapsid, dating back to the lower-middle Permian period.
  • Using advanced dating methods, researchers created a timeline showing that therapsids diversified rapidly after Olson's Extinction, suggesting they emerged in tropical Pangaea's wet biome rather than in cooler regions.

Article Synopsis
  • Researchers have uncovered that deoxidized SrTiO becomes metallic and superconducting at very low oxygen vacancy levels, challenging long-standing assumptions.
  • Detailed studies show that during thermal reduction, oxygen is lost at extremely low concentrations, leading to the formation of filaments along dislocation networks in the material.
  • The findings suggest a rethink of superconductivity models in self-doped SrTiO, proposing that the material behaves as a nano-composite with both insulating and metallic characteristics, facilitating polaronic coupling.
