Spotted:  A group of Cambridge scientists have created a small brain that can develop "tendrils" to connect and control muscles. This is a first for a lab-grown brain, according to the university. Miniature brains grown in a petri dish (known as a cerebral organoid) are created using stem cells submerged in a vitamin-rich gel. The process allows scientists to explore some aspects of brain development-- but not all. The miniature brains would die before they could develop beyond a set point because the gel cut off the oxygen supply. This limited how much scientists could learn. They could, for instance, study…
