The world's first "living computer" was made from human brain tissue by scientists in Sweden. This could change the way computers work and how much energy they use.

Brain organoids are used by the startup FinalSpark to do very complicated calculations using this groundbreaking new technology. The live computer comprises 16 organoids, groups of brain cells grown in a lab.

These organoids talk to each other like computer chips. They send and receive messages through neurons, working like circuits but using much less power.

This biocomputer has the potential to transform energy-intensive data centers completely. Living neurons consume nearly a million times less energy than modern digital processors.
