flag Swiss scientists use lab-grown brain cells to build energy-efficient biocomputers for AI and disease research.

flag Scientists in Switzerland are developing biocomputers using lab-grown human brain organoids—tiny clusters of neurons from stem cells—to create energy-efficient "wetware" processors. flag These organoids, about the size of a fruit fly’s brain and containing roughly 10,000 neurons, are kept alive with nutrients and monitored via electrodes that detect electrical signals used for basic computation. flag Co-founded by Fred Jordan, startup FinalSpark aims to harness the brain’s natural efficiency—biological neurons are one million times more energy-efficient than silicon chips—to address the growing power demands of AI. flag The technology has already enabled simple robots to recognize braille and is being used to study autism and Alzheimer’s. flag Though organoids lack consciousness and pain receptors, unexpected neural activity, like spikes when lab doors open, underscores gaps in understanding. flag While still in early stages, researchers see long-term potential for transformative advances in computing and neuroscience.
