Nancy Kress's novella "The Erdmann Nexus" won a Hugo yesterday. It's basis is a combination of the philosophical and scientific concept of emergence in complex systems along with a bit of neuroscience. In particular she uses the fact that activity in the brain changes when people go into deep meditative states as an indication that humanity could develop a group mind that goes beyond basic human consciousness. It's not a new science fictional idea, and not surprisingly the story has significant religious and mystical themes. I didn't find the story that interesting, other than Kress's inclusion of some recent science.
Read The Erdmann Nexus.
