As a science journalist, I get all kinds of magazines, brochures and fliers from universities and academic societies, inviting me to learn about new research and attend science conventions. None has ever caught my attention like this amazing flier, which arrived in my mailbox today.
Announcing a study about "gay genes" is one thing—featuring cartoon mice as the stars of "Brokeback Mountain" is something else altogether. Update: We've got the story from the flier's creator.
