Researchers at the Melbourne start-up Cortical Labs have made a groundbreaking advancement by teaching a biological computer, composed of living human brain cells, to play the iconic video game Doom. This project involved the use of between 200,000 to 800,000 brain cells derived from stem cells, which were specifically engineered to simulate the functions of a typical human brain. According to Dr. Alon Loeffler, a scientist at Cortical Labs, this innovation represents the first instance of a deployable biological computer capable of executing programmed tasks, potentially opening avenues for real-world applications like drug testing and robotics.

Dr. Loeffler explained that the project's early access user was able to engage with the game in a one-week program designed for the biological computer. The cells demonstrated an ability to navigate the game's environment in a way that mimics a functioning human brain. It's important to note that, while the cells are human brain cells, they are not sourced from actual human brains but are instead derived from blood donations, which raises interesting ethical considerations about the use of biological materials in technology.

This advancement highlights significant implications for the future of computing, where biological systems could complement or even surpass traditional silicon-based technologies. As researchers continue to explore the capabilities of biological computers, the integration of such systems into various fields could revolutionize industries that rely heavily on artificial intelligence and complex computations, ushering in a new era of technological innovation.
