Robo-fish swim into the ocean's funk, so you don't have to

Gene Roddenberry would have you believe that space is the final frontier. But really, the deep blue sea is more apt for that distinction. And without mega-rich hobbyists to fund exploratory plunges into those uncharted depths, science has had to seek out an alternative, more cost-effective means. Enter the robotic fish. Measuring five feet in length (1.5 meters), lasting up to eight hours and costing about $32,000 (£20,000), these cyborg swimmers are made to boldly go where no man should - that is, into contaminated waters.
