According to Futurism, clusters of nerve cells, known as mini-brains, grown at the University of California, San Diego were sent to the International Space Station, where they have been developing and replicating in ways previously thought as impossible.
The organoids were created in the lab of biologist Alysson Mutroni, who has found that they are giving off brain waves similar to those of premature infants. The mini-brains were integrated with spider-shaped robots to read their neural activity, and results have indicated that the scientific community is close to creating at least partially-conscious life.
These mini-brains simulate some characteristics of the human brain, but as scientists are still not entirely sure how many aspects of the brain work, a completely sentient artificial organ is not possible just yet.
With this breakthrough arises an ethical dilemma: as progress continues to be made in the development of artificial life, how far can we morally go in creating, and thus taking, life?
