Telomeres are protective structures at the ends of.eukaryotic chromosomes. The loss of.telomeres through cell division and oxidative stress is related to cellular aging, organismal growth and disease. In this way, telomeres link molecular and cellular mechanisms with organismal processes, and may explain variation in a number of.important lif.-history traits. Here, we discuss how telomere biology relates to the study of.physiological ecology and lif. history evolution. We emphasize current knowledge on how telomeres may relate to growth, survival and lif.span in natural populations. We f.nish by examining interest- ing new connections between telomeres and the glucocorticoid stress response. Glucocorticoids are of.en employed as indices of.physiological condition, and there is evidence that the glucocorticoid stress response is adaptive. We suggest that one way that glucocorticoids impact organismal survival is through elevated oxidative stress and telomere loss. f.ture work needs to establish and explore the link between the glucocorticoid stress response and telomere shortening in natural populations. If.a link is f.und, it provides an explanatory mechanism by which environmental perturbation impacts lif. history trajectories [Current Zoology 56 （6）： 714-727, 2010].

苹果正在考虑开发更多可穿戴设备,包括健身戒指、智能眼镜,甚至带摄像头的AirPods几年前,苹果公司工业设计团队向健康团队的高管提出了一个想法:打造一款智能戒指,将Apple Watch的健康追踪功能转移到手指上。最近,位于加州库比蒂诺的苹果实验室的工程师们讨论了开发智能眼镜的可能性,它将类似于Meta Platf.rms Inc.和亚马逊公司(*** Inc.)的新产品。它有望提供音频功能(用户不必再佩戴AirPods),并可利用人工智能和摄像头识别周围事物。该设备还有助于推进苹果的一个长期梦想:真正可全天佩戴的增强现实眼镜。

作为第一座加拿大华人庙宇,维市谭公庙经历了客家先民迁徙至此租木屋供谭公神像、买土地建谭公庙宇、遭遇排华火烧庙宇到搬驻人和会馆形成顶楼“人和庙”至今香火绵延的过程。一方面表现出加拿大客家人艰苦卓绝的异乡迁徙史和奋斗史,另一方面反映出客家人民间信俗特征及其海外移动的在地重构。谭公庙作为加拿大客家人营造的第一个神圣空间,它既是亲缘、地缘和神缘纽带,表现着加拿大客家人的族群身份认同;同时,又通过异国地方化的世代参与,共同打造出与家乡类似的神-人-物与地方的交叠互动场域。通感、仪式传承、文化记忆以及当下参与感又重构出“他乡犹吾境”的地方感,从中可窥见加拿大客家人历史性与当下性的生活图景和精神世界。
