...Technology, estimates that 4% to 5% of the genes in a cloned animal's genome are expressed incorrectly--probably because of faulty methylation. "If you reprogram, it affects the whole genome," he says. "From what we know, I would argue that cloned animals cannot be normal. They can be closer to normal, but not normal...
...cells. Telomeres are bits of DNA that sit at the ends of chromosomes and serve as a biological clock chronicling a cell's age. In general, the shorter the telomeres, the older the cell. Dolly, a clone of a 6-year-old ewe, had cells whose telomeres were closer in length to those of her biological mother than to those of a baby lamb. We will never know, though, whether her shortened telomeres would have shortened her life. In 2003 Wilmut and his team decided to put Dolly to sleep after she developed lung cancer caused by a viral infection...

What was less expected is that when kids grow up with an opposite-sex sibling, such exposure doesn't temper gender-linked traits but accentuates them.

"I'm very sensitized to the fact that it's important to listen to others," a respondent wrote in a recent study conducted in Britain. "People get over their anger, and people who disagree...
