Developmental biologists successfully coaxed human stem cells into spontaneously growing microscopic three-dimensional brain organoids in a petri dish that actually developed…

HERE’S THE INTERESTING PART

Biology has officially entered its mad scientist era. We aren't just cloning cells; we are coaxing stem cells to spontaneously self-assemble into 3D mini-brains in glass dishes. These clumps of tissue are so eager to develop that they literally grow their own rudimentary, light-sensitive eyes, staring back at the scientists who created them.
