We’re all going to die; DNA strands on the end of our chromosomes hint when

(Feb.6, '15) New research finds new link between these biological clocks and lung disease

BYU biologist Jonathan Alder has a startling secret he doesn’t freely share: he knows when most of us are going to die.

OK, he doesn’t know exactly the day or time, but he has a pretty good idea, thanks to his research on tiny biological clocks attached to our chromosomes. These DNA end caps, called telomeres, are the great predictors of life expectancy: the shorter your telomeres, the shorter your lifespan.
