National University of Singapore launches world-first data center powered by human brain cells

A data center in Singapore is now running on human brain cells. That sentence reads like the opening crawl of a sci-fi movie, but it’s a real thing happening at the National University of Singapore’s Life Sciences Institute, where 20 biological computing units containing lab-grown human neurons went live on July 16. The system, publicly unveiled on August 6, represents the world’s first independently operated biologically integrated server rack. It was built through a collaboration between NUS Medicine’s Yong Loo Lin School of Medicine, Melbourne-based biotech startup Cortical Labs, and Singapore data center operator DayOne. How it works, without the sci-fi jargon Each of Cortical Labs’ CL1 units houses between 200,000 and 800,000 human cortical neurons grown in a lab, not harvested from anyone’s skull. These neurons sit on silicon-based microelectrode arrays, creating a hybrid system where biological tissue and traditional chips work together. The cells need feeding every three days and are kept alive by dedicated life-support equipment that maintains precise gas mixtures of CO2, oxygen, and nitrogen, along with carefully controlled temperatures. Their operational lifespan runs ab...
