Scientists open new window into how cancers override cellular growth controls
Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.

Telomere length in young zebra finches predicts lifespan
(PhysOrg.com) -- For hundreds, if not thousands of years scientists have been seeking clues to explain why we humans, and all other animals for that matter, age. But it’s been only recently that some ...

A new ending to an old 'tail'
In stark contrast to normal cells, which only divide a finite number of times before they enter into a permanent state of growth arrest or simply die, cancer cells never cease to proliferate. Now, scientists ...

Exercise may prevent stress on telomeres, a measure of cell health
UCSF scientists are reporting several studies showing that psychological stress leads to shorter telomeres – the protective caps on the ends of chromosomes that are a measure of cell age and, thus, health. The findings ...
