现在全球的能源技术将进入这一乔细胞磨损。
Global Energy Technologies will now enter this Joe Cell fray.
很多生物学家仍认为停止衰老只是一个幻想，因为我们永远不能克服细胞过段时间就会死亡，以及基因组的消耗磨损等生物程序。
Plenty of biologists still say it's a mirage because we will never overcome the biological programme whereby cells die after a certain time, or indeed the rigours of wear and tear on the genome.
细胞每复制自己一次(细胞在死亡之前都会如此)，其端粒就会缩短，就像鞋带的塑料头会磨损一样。
Each time a cell replicates itself (as it does before it dies), the telomeres shorten, like plastic tips fraying on the end of shoelaces.
当这些微型染色体注入到酵母细胞中后，在细胞分裂时，这种CCCCAA的DNA序列在复制时对染色体起到了保护作用，就像鞋带末端的塑料帽对鞋带起到的防磨损作用。
When these were injected into yeast, the DNA sequence protected the chromosomes when they were copied, just as the plastic tips at the ends of shoelaces stop them from fraying.
随着细胞老化，它们会缩短、磨损，不过这一过程不完全由时间决定。
They shorten and fray as a cell ages, although the process is not strictly chronological.
