Computers powered by human brain cells may sound like science fiction, but a team of researchers in the US believe that's achieveable within our lifetime.
Using organoids - which are lab-grown tissues resembling organs like the brain - scientists say they're close to creating a biocomputer which beats even artificial intelligence.
It's part of a burgeoning field of study called "organoid intelligence".
Johns Hopkins Bloomberg School of Public Health professor Dr Thomas Hartung is a senior author on the study.
He spoke to Corin Dann.
