SF Signal has a wonderful forum they call Mind Meld. A provocative SFFnal question is posed for SF writers and other people to contribute answers. Most recently there was this question:
What current avenue of scientific inquiry do you believe people should be paying attention to, and why?
This was pondered by Kathleen Ann Goonan, Nancy Kress, Mike Brotherton, Nina Munteanu, Jennifer Ouellette, Kay Kenyon and myself. Our answers are at http://www.sfsignal.com/archives/006823.html.
