In travellings across the internet, I’ve tried to discover the best sources for the conversation about science fiction. My recent find was the blog Biology and Science Fiction This blog is a unique source for opinion about science fiction and the genetic and physical possibilities and impossibilities. Peggy is both well-read, and intelligent. She brings a great deal of intelligence to her writing. I do sometimes disagree with her opinion, but that doesn’t remove the value of the blog. So, if you wish to discover a good science fiction blog that tries to make you think, check out this one.
