Researchers at Cortical Labs in Melbourne have successfully trained a biological computer made from living human brain cells to play the game 'Doom.' This innovative breakthrough represents a significant advancement in the field of biological computing, potentially paving the way for applications in drug testing and robotics. The experimental setup involved approximately 200,000 to 800,000 brain cells derived from stem cells, demonstrating the capabilities of synthetic biological intelligence.

Dr. Alon Loeffler from Cortical Labs highlighted that this project is the first instance of a deployable biological computer, which they refer to as a neurocomputer. The cells used in the project are not sourced from human brains, but instead obtained from blood donations, which ensures ethical considerations are met. During a one-week program, the neurocomputer was able to navigate a version of 'Doom', engaging with the game environment in a manner similar to human cognitive processes.

The implications of this research extend beyond mere gaming; it suggests that biological computers could play a role in vital sectors like pharmaceuticals, potentially streamlining drug discovery processes or enhancing robotic functions. The development of such technology raises important ethical and technological discussions regarding the use of biological materials in computing and their potential impact on industries reliant on artificial intelligence.
