How the classic computer game Doom became a tool for science

Doom Unleashed: How a 1990s Game Became a Playground for Science. Step into the world of Doom, a 1993 computer game that launched a thousand adventures—not only for gamers, but also for scientists. Far from its pixelated corridors, Doom has become a surprisingly powerful tool for exploration across diverse scientific frontiers. It's not just nostalgia at work—this game's open-source code and cult status have driven researchers to push the boundaries of what's possible. The phrase “Can it run Doom?” has become an online rallying cry, and the game's adaptability is the stuff of legend. Scientists have run it on everything from calculators to digital pregnancy tests, always chasing the thrill of making the impossible possible. But the most astonishing experiments bring Doom to life in ways never imagined by its original creators. Picture this: living neurons grown on silicon, taught to play Doom's complex world. Australian researchers trained these brain cells to navigate the game, building on previous work where neurons mastered Pong. Why Doom? Its memes and cultural cachet made it the ultimate challenge— a playful nod to internet lore, but also a testbed for biological intelligence. This playful spirit isn't just about fun. There is a deep connection between the creativity needed to make quirky experiments work and the ingenuity required for scientific breakthroughs. Play fuels curiosity, and curiosity drives discovery. “Making something silly doesn't take any less work than making something really technical,” one scientist points out, highlighting how fun can spark serious insight. Doom's open-source nature is key. Since its code was released to the public in 1997, tinkerers and researchers have repurposed it for all sorts of projects. Its lightweight design makes it easy to adapt, and its iconic status ensures a steady stream of challengers eager to see how far they can push its limits. The game's scientific applications don't stop with neurons. Doom has been displayed using fluorescent bacteria, with each cell acting as a pixel to recreate the game's frames in a petri dish. It’s even been run on satellites, showing that the urge to experiment knows no earthly bounds. Doom is part of a broader tradition of games in science. Minecraft has served as an AI testbed, and online worlds like World of Warcraft have modeled real-world phenomena such as disease outbreaks. Yet Doom’s combination of accessibility, technical simplicity, and cultural mystique makes it uniquely beloved. So, what began as a first-person shooter has become a proving ground for innovation—where play, science, and a mischievous sense of possibility collide. Doom isn't just a relic of the past; it's a reminder that sometimes, the best science starts with a simple, playful question: Can it run Doom?
