376. 衰老时钟与逆转衰老
from 知为谁 · host 知为谁
文本探讨了衰老时钟这一新兴科学工具，这些时钟利用DNA甲基化等生物标记物来测量个体的生物年龄，而不是仅仅依赖其实际年龄。这些时钟，例如Horvath时钟和GrimAge时钟，被科学家用来更好地理解衰老的机制和人类的寿命，甚至可能帮助寻找逆转衰老的方法。文章指出，尽管衰老时钟在研究中非常有用，但它们的准确性和个体预测能力仍有局限，并且存在被长寿影响者和保健品销售者滥用的风险。此外，文中还介绍了异时性共生等动物实验，表明生物年龄在一定程度上具有可塑性，并且探讨了生命的起点与衰老的开始在胚胎发育阶段的关联。内容来源：https://www.technologyreview.com/2025/10/14/1124977/aging-clocks-biology-mortality-longevity/
