Picture a dystopian future where computers don’t just mimic human thinking – they’re powered by actual human brain cells. That future is taking shape in a Cambridge, England, lab, where a groundbreaking device called CL1 is blending biology and technology in ways that could transform how we compute. Developed by Australian startup Cortical Labs and U.K.-based bit.bio, this shoebox-sized machine houses 200,000 lab-grown brain cells wired to silicon circuits, creating a “biological computer” that’s already turning heads.
Unlike traditional computers, which guzzle energy, CL1 operates with the efficiency of a human brain. “Our brains process information using a fraction of the power that modern electronics need,” Hon Weng Chong, CEO of Cortical Labs, told FT. “This could open doors to smarter robots, stronger cybersecurity, and immersive virtual worlds.”
Oh, joy.
Low-energy computing has fueled a race to develop biological systems, with Cortical Labs leading alongside competitors like FinalSpark in Switzerland and Biological Black Box in the U.S.CL1’s brain cells, grown from human skin-derived stem cells, are carefully arranged in layers: one type sparks electrical activity, while another keeps it in check. “It’s like balancing a gas pedal and brakes,” Chong explains. This precision, says bit.bio’s Tony Oosterveen, gives CL1 an edge over rival approaches using less uniform “mini-brains.” The result is a platform for testing how brain cells handle information, with early experiments already yielding insights for neuroscience and drug development.
