If Telomeres Thrive, You Will Survive

Augmenting chromosome caps extends worm life span

Abstract: Much as cutting the biblical muscleman Samson's hair sapped his strength, trimming telomeres weakens a cell's power to survive. A new study of nematodes backs the idea that extending chromosome tips prolongs an animal's life span. The findings add a new twist by suggesting that lengthy telomeres stretch life not by affecting cell duplication, but by solidifying defenses against stress.
