If everybody switched to organic farming, we couldn't support the earth's current population - maybe half.

Myths about the dire effects of genetically modified foods on health and the environment abound, but they have not held up to scientific scrutiny. And, although many concerns have been expressed about the potential for unexpected consequences, the unexpected effects that have been observed so far have been benign.

One of the really remarkably beneficial aspects of genetic engineering is that much of the previous methodology for controlling pests and so forth is through chemicals that affect a very broad spectrum of insects, for example, or fungicides that control fungi.

Jumping genes are fundamental because they're agents of change. Everybody knows that organisms evolve. What makes them evolve is that their genes are dynamic and in motion. A familiar example is the stripe-y corn - called Indian corn - that you buy in the fall.

My father worked in high-energy nuclear physics, and my mother was a mycologist and a geneticist. After both parents completed postdoctoral fellowships in San Diego in 1962, my father took a faculty position in the Physics Department at Yale, and so the family moved to New Haven, Connecticut.

As physics students, we are taught that physicists are smart, that chemists are moderately acceptable, and that biologists are certainly not very intelligent. So I wasn't inclined to take a biology course. But my father insisted, and maybe what he had in mind was that, if there were no jobs in physics, I would end up being a doctor.

Eye was a great discovery. He is one of the great vocalists of all time.

I'd love to present a popular science programme because it's something I feel very passionate about.
