Oh science, why are you going there? Haven't you seen the movies? Don't you know what your insatiable thirst for knowledge is bound to wreak? Hapless roboticists at Reading University are working on building a robot octopus that will move, react and grasp objects just like an actual octopus. Such a creature could be invaluable for performing underwater tasks -- such as maintaining watercraft or salvaging Le Cœur de la Mer. Currently, they've only got one working tentacle, but if the project goes as planned, they'll have an entire autonomous, battery-operated creature in a few years. Oh, swell.
