mini brains

Scientists have successfully grown brain organoids — tiny, three-dimensional tissue cultures that mimic the real thing — each with their own set of 'eyes.'

It's as creepy as it sounds.

Scientists Just Grew These Grotesque Mini Brains With “Eyes” in a Lab

To study how early humans related to Neanderthals, a team of European scientists grew mini brains from human stem cells that contain Neanderthal DNA.

"We were curious how much of the Neanderthal genome could be explored if you just have access to stem cells from the right people."

Biological "hybrid computer chips" could drastically lower the amount of power required to run AI systems.

This Startup's Computer Chips Are Powered by Human Neurons

As lab-grown mini brains become increasingly complex, some neuroscientists warn that scientists may be creating and killing off sentient life.
