Author and scientist Dan Koboldt has a series of guest blog posts on his website called 'Science in Sci-Fi, Fact in Fantasy'. The posts cover a wide variety of topics often used in writing SFF (zombie microbiology, anyone?), neatly organized by category. I thought this might be a useful resource so thought I'd share the link to his page.
