So it was thanks to their plentiful telomerase that our pond scum critters never got old.

因此， 正是们丰富端粒，我们池塘浮渣生物才不会变老。

But when we analyze the cells chemically we find something very interesting, a chemical in them, an enzyme called telomerase.

但是当我们对细胞进化学分析时， 我们发现了一些非常有趣东西，们中一种化学物质， 一种叫做端粒。

And when we removed our pond scum's telomerase, their telomeres ran down and they died.

当我们去除池塘浮渣端粒时，们端粒就会流失并死亡。

And in the future we may have virtually immortal nerve cells and immortal skin cells of whatever because of these chemical, telomerase can keep the telomere on the ends of Chromosomes from getting any shorter.

并且在未来，这些化学物质，端粒可以防止染色体末端端粒变短，因此我们可能拥有几乎不朽神经细胞和不朽皮肤细胞。
