MARK MEHLER (Albert Einstein College of Medicine): We're in the midst of probably the biggest revolution in biology that is going to forever transform the way we understand genetics, environment, the way the two interact, what causes disease. It's another level of biology, which, for the first time, really, is up to the task of explaining the biological complexity of life.
NARRATOR: Ghost in Your Genes, up next on NOVA.
Major funding for NOVA is provided by the following:
For each of us, there is a moment of discovery. We understand that all of life is elemental, and as we marvel at element bonding with element, we soon realize that when you add the human element to the equation, everything changes.
