Story summary

Scientists in Switzerland have developed computers powered by living human brain cells, called brain organoids.
The mini-brains were created by FinalSpark, a biotech startup, to serve as biological processors and to be more energy-efficient than silicon chips.
Researchers maintain organoids in nutrient-rich solutions to perform basic data processing tasks.
Ten universities are experimenting with this technology for robotics and neurological disorder studies, and ethical discussions continue.
