Scientists create living computer using human mini-brains
In a groundbreaking development in the field of biocomputing, scientists in Switzerland have successfully created a “living computer” powered by human mini-brains. This innovative system, known as “wetware,” utilizes lab-grown brain organoids—tiny clusters of human brain cells—to perform computational tasks traditionally handled by silicon-based processors.
The project, led by the Swiss startup FinalSpark, involves cultivating these organoids from human stem cells and connecting them to electrodes that allow researchers to monitor and influence their activity. These organoids, each no larger than a few millimeters in diameter, exhibit electrical activity similar to that of a human brain, enabling them to process information in a manner akin to biological neural networks.
One of the most significant advantages of this biocomputing approach is its energy efficiency. While traditional AI processors consume vast amounts of power, the human brain operates on approximately 20 watts of energy, a level of efficiency that wetware systems aim to replicate. Researchers believe that by harnessing the natural processing capabilities of brain cells, wetware could revolutionize fields such as artificial intelligence and neuromorphic computing.
Despite its promise, the development of wetware faces several challenges. The organoids have a limited lifespan and require precise conditions to maintain their viability. Additionally, ethical considerations regarding the use of human-derived brain tissue in computing applications continue to be a topic of debate within the scientific community.
Nevertheless, the creation of this living computer marks a significant step forward in the exploration of alternative computing paradigms. As research progresses, wetware systems may offer new insights into the intersection of biology and technology, potentially leading to more efficient and sustainable computing solutions.
