CHILDREN typically have the same life expectancy at birth, regardless of whether their father is 20 years old or 80. This must mean that the man's reproductive cells somehow reset their clocks, but how they do this has been a mystery. Now a gene that reverses ageing effects in yeast is providing some clues.

孩童从出生开始通常都有相同寿命预期,无论小孩父亲当时是20岁还是80岁。这就是说,男子生殖细胞以某种方式会再次调整他们生命时钟,至于如何实现这种调整仍是个未解开的谜团。不过最近发现,有一种逆转衰老酵母基因给我们提供了寻找线索。
