A jellyfish-like hydrozoan with a novel power to rewind its life cycle has been spreading rapidly around the world’s oceans without anyone taking much notice, researchers say. The life history of Turritopsis dohrnii takes such twists and turns that only a new genetic analysis has revealed that the creature is invading waters worldwide, says Maria Pia Miglietta of Pennsylvania State University in University Park.

Believe it or not, science has barely begun to fathom the peacock’s tail. Subtle as a pink tuxedo, one might think. Big flashy thing. Peahens love it. What’s not to understand. Roslyn Dakin, though, has plenty of questions. There’s the matter of choreography. Already this year she has left Queen’s University in Kingston, Canada, to visit peacocks (the birds) in Los Angeles and New York. She has spent weeks collecting feathers and watching males fan out their finery before the ladies. “The males do all sorts of strange footwork,” she says. With their tails a wall of shi...
