A biotech researcher from MIT proved it run the cult computer game Doom using real gut bacteria. Lauren Ramlan turned real bacteria into pixels to display a 30-year-old FPS.
She specifically created Ramlan a 32×48 one-bit display inside a cell wall made entirely of E. coli bacteria. The researcher dosed the bacteria with fluorescent proteins to make them light up just like digital pixels. The bacteria thus functioned as a small monitor that rendered the game. At the same time, the frame rate was understandably completely insufficient – it took the bacteria 70 minutes to light up one frame of the game, and another eight hours to return to the initial state. This means that one picture took almost nine hoursmeaning it would take approximately 600 years to play the game from start to finish.
However, even if it’s not the smoothest gaming experience, it’s an interesting example of that Doom can run on virtually anything. We’ve seen the game run on pregnancy tests, rat brain neurons, an LED bulb, a chip, and even inside other titles like the sequel to Doom II or Minecraft.
