Even after the scientists corrected for factors such as age and body-mass index, those crucial cells looked different--in three important ways--in the women who reported the highest stress levels. First, the cells had shorter telomeres--bits of DNA that cap the ends of chromosomes. In lab experiments, scientists have shown that telomeres get a bit smaller every time a cell divides, and that when telomeres are worn out, cells can't divide anymore and ultimately die. In humans, older people tend to have shorter telomeres--and by this measure, the most stressed women in the study...
...type of highly reactive molecule that can damage DNA. One might argue that women whose children were born with those disorders already had something wrong with their DNA and that stress wasn't the cause. But that wouldn't explain another crucial fact: the degree of cellular damage was highest in women who had been caring for a disabled child the longest. "We tried our hardest to make the result go away," says Blackburn, "because we wanted to make sure we weren't fooling ourselves. But we couldn...
...fabulously flamboyant Americans, Andrew Jackson and Mark Twain. The Jackson portrait is dynamic, wind whipped, but slightly obligatory.

Although neither of the Nativities marks a moment for the beginning of her ensuing pregnancy, Christians have long assumed it followed directly upon her "Let it be" response...
