Trailer
In this episode of NOVA scienceNOW, journey back in time to the birth of our solar system to examine whether the key to our planet's existence might have been the explosive shockwave of an ancient supernova. Meet a chemist who has yielded a new kind of "recipe" for natural processes to assemble and create the building blocks of life. And see how the head louse, a creepy critter that's been sucking our blood for millions of years, is offering clues about our evolution. Finally, meet neuroscientist André Fenton, who is looking into erasing painful memories with an injection.
