Johns Hopkins researchers break ground on new field of ‘organoid intelligence’. According to researchers at Johns Hopkins University, a 'biocomputer' powered by human brain cells could be developed within our lifetime. This technology is expected to exponentially expand the capabilities of modern
Organoid intelligence is an emerging scientific field that seeks to create biocomputers by utilizing lab-grown brain organoids as “biological hardware.”According to researchers at

Each organoid contains about 50,000 cells, about the size of a fruit fly’s nervous system. He now envisions building a futuristic computer with such brain organoids.
“The brain is still unmatched by modern computers,” Hartung said. “Frontier, the latest supercomputer in Kentucky, is a $600 million, 6,800-square-feet installation. Only in June of last year, it exceeded for the first time the computational capacity of a single human brain — but using a million times more energy.”
Organoid intelligence could also revolutionize drug testing research for neurodevelopmental disorders and neurodegeneration, said Lena Smirnova, a Johns Hopkins assistant professor of environmental health and engineering who co-leads the investigations.
