Pac-Man Gets a Biotic Upgrade: Now Gamers Play It With Microbes

Pac-Man is looking different these days–he’s slimmed down, translucent, and has grown a mane of cilia. And he’s also alive. Meet Pac-Mecium, one of eight “biotic games” developed by Stanford physicist Ingmar Riedel-Kruse and his team. For the first time in gaming history, players directly “control” living organisms such as paramecia–a breakthrough that could lead to the baby boom of citizen scientists.

In a paper published in the journal Lab on a Chip, the researchers describe the games they made with names like “Biotic Pinball” and “POND PONG” and “Ciliaball,” in which humans interact with everything from a few molecules to colonies of cells. In the case of PAC-Mecium, a game board image is projected over a paramecium, and while the player sees the image via a live camera, the paramecium’s progress and score are accounted for by a microprocessor. As Stanford News reports:

The player attempts to control the paramecia using a controller that is much like a typical video game controller. In some games, such as PAC-mecium, the player controls the polarity of a mild electrical field applied across the fluid chamber, which influences the direction the paramecia move.  In Biotic ...

Did Google Pac-Man Destroy Worker Productivity? We’re Unconvinced.

Expletives and MIDI music rose from office cubicles this past Friday: Pac-Man had returned. On May 21, Google replaced its usual blue, yellow, red, and green title with what the company calls a "doodle."  But unlike previous replacements, which have celebrated everything from Pi day to Norman Rockwell's birthday, for Pac-Man's special day (the 30th Anniversary of the game's Japan release) Google pulled out the big guns, er, ghost-eaters. This time, the doodle was an animated and playable version of the 1980s Namco video game, complete with our pie-shaped hero and his multicolored ghost foes: Blinky (red), Pinky (pink), Inky (cyan), and Clyde (orange). But some kill-joys complain that Friday's Pac-Man play hindered productivity, and set out to determine just how much money had been frittered away as employees avoided their work. The BBC reports that the firm Rescue Time tracked 11,ooo users' online activity and noticed that Pac-Man kept them on Google's site about 36 seconds longer than usual. Multiplying those 36 seconds by Google's 504 million users, that means over 500 years worth of work time spent playing. The firm estimates an average worker's salary at $25 an hour for a grand total of about $120 million in lost productivity. How Rescue Time ...
