Telomeres--the ends of chromosomes--shorten during each round of cell replication, suggesting that they dictate the number of times a cell can divide before it reaches senescence. Almost all cancer cells and other immortalized cells thwart that stop mechanism by expressing telomerase, an enzyme that, in effect, rebuilds the chromosomal tips.

In an earlier Hot Paper feature (The Scientist, 10[11]:14, May 27, 1996), Jerry W....
