科学家们正在研究三位巴西姐妹，她们的年龄总和为316岁，已被吉尼斯世界纪录认证为现存最年长的三姐妹组合。由圣保罗大学的Mayana Zatz领导的DNA Longevo项目旨在揭示导致她们非凡长寿的遗传和生活方式因素。通过将这些百岁老人与经历过与年龄相关的衰退的个体进行比较，研究人员希望能够识别出保护性基因并理解衰老韧性背后的生物学机制。 AI

What is the secret to a long life? Three Brazilian sisters with a combined age of 316, who were named by Guinness this month as the oldest living trio of siblings in the world, may help researchers find out. The DNA Longevo Project, a study led by scientist Mayana Zatz from th…
