A group of scientists in Switzerland are trying to create computing power using brain cells, in a field called biocomputing.

One day, they hope we could see data centres full of "living" servers which replicate aspects of how artificial intelligence learns - and could use a fraction of the energy of current methods.

It involves creating neurons which are developed into clusters called organoids, which in turn can be attached to electrodes - at which point the process of trying to use them like mini-computers can begin.

Reporting for BBC Tech Now, Zoe Kleinman meets the researchers.
