The single biggest threat to man's continued dominance on the planet is the virus.

By the time I was 12 or 13, I was studying biochemistry textbooks.

I get curious about new things. My real strength is going into a field that has not been investigated before, and finding new approaches to it.

All of civility depends on being able to contain the rage of individuals.

I have many shortcomings. I feel very lucky to have been able to have what I've had.

Try hard to find out what you're good at and what your passions are, and where the two converge, and build your life around that.

If we have isolated individuals able to inflict enormous harm, imagine what a single lunatic can do with a nuclear weapon. I think the whole base of civil society is at risk.

I'd like to put in a vote for the intrinsic fascination of science.

That's the reason I left the networks. I wanted to write and report and coanchor.

You have to discipline yourself and not carry the character with you. You need to switch it off and take time to re-energize.

Mark what a generosity and courage (a dog) will put on when he finds himself maintained by a man, who to him is instead of a God

If atheism is a religion, then off is a TV channel and bald is a hair colour.

I like doing things that are very wildly different. I find that the meat and vegetables of being an actor is doing things that are completely different, all the time.

Well I'm trying to think what I put in... I think I put in 'why?' to see if I'd confuse the computer.

The Eleanor Roosevelt Award that I received for women's rights activities is one I treasure
