New tools offer clues to how the human brain takes shape

Credit: Adam Gault/Getty ImagesEthical debates often accompany major scientific advancements. Consider the 1970s and 1980s, when in vitro fertilization research really took off. In response to concerns about what might constitute life, the scientific community adopted a principle that no one should ever allow embryos in vitro to develop to the point where a brain started to form.Fast forward to the present. Advances in the development of cerebral organoids — brain structures generated in labs from stems cells, or "brains in a petri dish," as some call them  — have brought about possibilities that never could have been imagined when the debates over in vitro fertilization occurred. “When the principle of not developing a brain in an in vitro embryo was formulated, the only way it was envisioned that a brain could be developed in vitro was in an embryo, but cerebral organoids show that is obviously no longer true,” Harvard Medical School geneticist John Aach told Seeker. “So, one issue is
