OK, this one is so good you have to read the complete post. Every word!
Dr. Kiki Sanford is self-described as PhD scientist (neurophysiology) who escaped the lab to be a science writer. Recently she blogged the fundamentals for good science communication.
In a nutshell: Tell a story.
Word of Warning: I know Dr. Kiki from the Conference on World Affairs as an articulate TKD black belt. Not a person to ignore!
