"DAY ONE 5:10 pm
It's late on a Sunday afternoon and nearly dark inside the tiny, windowless lab; fluorescent light is said to be bad for human embryos. I'm sitting beside Robert Lanza, medical director at Advanced Cell Technology. He's breathing softly, hands folded neatly in his lap, his head bowed as if in meditation. For years he's been preparing for this day - making plans, conducting preliminary tests, losing sleep. Now, on October 12, we're six hours into the experiment and all he can do is watch."
