Two-faced space worm could inform regenerative medicine

It sounds like the plot of a science fiction movie: Worms sent into space return to Earth with two heads. But it isn’t fiction at all. In a recent study, researchers sent worms with regenerative capabilities — some left whole and some cut into pieces — to the International Space Station (ISS) to study how the worms’ bodies would respond in space and whether their behavior might help efforts to treat human ailments.
