Play Pacman, Pinball, and Pong With a Paramecium
An anonymous reader writes "Science is rarely ever this cool! 'Physicist Ingmar Riedel-Kruse and his team from Stanford University have done just that by creating versions of classic games that you can navigate by physically controlling living organisms. A game called PAC-mecium is Pacman with a twist: players use a console to change the polarity of an electrical field in a fluid chamber filled with paramecia, which makes the organisms move in different directions. A camera sends real-time images to a computer, where they are superimposed onto a game board (see video above). By looking at the screen, a player can guide the paramecia to eat virtual yeast cells and make them avoid Pacman-like fish. A microprocessor tracks the movement of the organisms to keep score.' Also available are versions of Pinball, Pong, and soccer."
Some higher species might be doing the same thing with us humans.
uhh...it's worse than dog fights? You're trolling, right? Dogs are social, self-aware beings that can solve complex problems, have emotions, form social bonds, suffer, experience joy, etc. Paramecium...are single-celled organisms. You might as well be concerned about torturing a rock, or air; they have no ability to feel pain, and certainly no ability to suffer.
