This episode of NOVA scienceNOW weighs the risks against the benefits of getting a personal genetic profile; takes a closer look at algae, and asks if it may be the biofuel of the future; explores the undersea Gakkel Ridge, deep in the Arctic Ocean, for clues that one of Jupiter's moons may host life; and profiles Yoky Matsuoka, a leader in the emerging field of neurobotics - the fusion of neuroscience and robotics.
