For years, even before 9/11, I've been trying to warn that the threat from amateur biolabs will ultimately turn out to be far more troublesome than leakage from military labs - perhaps even more costly and deadly than nuclear terrorism.

Ray Bradbury is, for many reasons, the most influential writer in my life. Throughout our long friendship, Ray supplied not only his terrific stories but a grand model of what a writer could be, should be, and yet rarely is: brilliant and charming and accessible, willing to tolerate and to teach, happy to inspire but also to be inspired.

I do read a lot, and I think in recent years the ratio between the amount of non-fiction and fiction has tipped quite considerably. I did read fiction as a teenager as well, mostly because I was forced to read fiction, of course, to go through high school.

Sometimes you see films, not just science fiction films, where you get the sense that if the camera were to pan just to the left or the right, all of a sudden you'd be seeing light stands and crew standing around. But with 'Blade Runner,' the beauty of it is that it felt like a real, breathing city.
