Scientists grow mini human brains to power computers

It may have its roots in science fiction, but a small number of researchers are making real progress trying to create computers out of living cells. Welcome to the weird world of biocomputing. ... We are all used to the ideas of hardware and software in the computers we currently use. The somewhat eyebrow-raising term Dr Jordan and others in the field use to refer to what they are creating is "wetware".

... In simple terms, 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.
Graphic explaining how skin cells are turned into "mini brains," illustrating a three-step process: 1) human skin cells are turned into stem cells; 2) stem cells are cultured into neuron clusters forming organoids, and 3) organoids are connected to electrodes after several months.

Dr Jordan acknowledges that, for many people, the very concept of biocomputing is probably a bit weird.

"In science fiction, people have been living with these ideas for quite a long time," he said.

"When you start to say, 'I'm going to use a neuron like a little machine', it's a different view of our own brain and it makes you question what we are."

For FinalSpark, the process begins with stem cells derived from human skin cells, which they buy from a clinic in Japan. The actual donors are anonymous.

But, perhaps surprisingly, they're not short of offers.

"We have many people who approach us," he said.

"But we select only stem cells coming from official suppliers, because the quality of the cells are essential." ...
