It's fashionable to speak about vulnerable populations in medicine and public policy, but it's harder to find a more vulnerable population than those who are dying.

It used to be thought that our genes were historically immutable and that it was not possible to imagine a conversation between culture and genetics.

It is well to look around at whom, and not just what, surrounds us. Population structure will change everything. Our health, wealth, and peace depend on it.

Everyday interactions we have with other people are definitely contagious, in terms of happiness.

What constrains or enables the capacity of human beings to work in groups is not so much the technology, but rather the capacity of the human brain to have and monitor social interactions.

Well, you've finally got a license to kill. It's about time.

Passion is sweeter split strand by strand. Divided and re-divided likemercury then gathered up only at the last moment.
