New research has revived one of the longest standing, and biologically fundamental, debates in the life sciences: Is there a set limit to how long humans can live? 一项新研究激起了一个老生常谈的基本生物学话题，也是生命科学领域的一个重要争议，那就是：人的寿命到底有没有上限？ The study, published in the journal Science, suggests that maybe there isn't. (It should be noted that this finding contradicts other, similar research by biologists and demographers, as Nature notes.) 这份研究报告发表在《科学》杂志上，意指人的寿命并没有上限。（《自然》杂志指出，这一发现与其他生物和人口统计学家作类似研究后的发现相矛盾。） Researchers examined a population of nearly 4,000 Italians who were 105 years or older. What they found was that mortality risk essentially plateaus after a certain point for these "super-elderly" individuals. 研究团队考查了大约4000名105岁及以上的高龄意大利人，他们发现在这些“超级年长”的人群中，过了某一节点后死亡风险反而趋于平缓。 |
