Australian startup Cortical Labs has launched what it’s calling the “world’s first code deployable biological computer.”

The shoe box-sized device, dubbed CL1, is a notable departure from a conventional computer, and uses human brain cells to run fluid neural networks.

In 2022, Cortical Labs made a big splash after teaching human brain cells in a petri dish how to play the video game “Pong.”

The CL1, however, is a fundamentally different approach, as New Atlas reports. It makes use of hundreds of thousands of tiny neurons, roughly the size of an ant brain each, which are cultivated inside a “nutrient rich solution” and spread out across a silicon chip, according to the company’s website.

Through a combination of “hard silicon and soft tissue,” the company claims that owners can “deploy code directly to the real neurons” to “solve today’s most difficult challenges.”

“A simple way to describe it would be like a body in a box, but it has filtration for waves, it has where the media is stored, it has pumps to keep everything circulating, gas mixing, and of course temperature control,” Cortical Labs chief science officer Brett Kagan told New Atlas late last year.
