Language -- the barrier and the bridge between science and public.
What does modern science tell people? That life is ultimately DNA, and DNA is genes, and genes are just so many bits of Lego, little building blocks manipulated by Nature for 3.8 thousand billion years, rather economically, so that much the same genes pop up in a nematode worm, a fruit fly, a lettuce, and a thriller writer. And that genes can be transferred from one species, or genus, or phylum, or even one kingdom to another. That is why there is unease, and newspapers reflect that unease, they do not create it. By helping people confront that unease, they probably help people come to terms with it. In the course of history, people have felt pretty uneasy about blood transfusion, heart transplants, test tube babies, and AIDS, and over the years, have calmed down considerably about each, to the advantage of both society and science. It will be the same for the human genome project, in a while.
