Researchers at Johns Hopkins Bloomberg School of Public Health have produced tiny brains made of human neurons and cells. These mini-brains could radically change how drugs are tested, replacing the many animals currently being used for neurological scientific research.
Every year, the Design Museum in London picks a single object and names it the best design of the year. It’s pretty bad sometimes! But this year the museum picked a winner: A chip that replaces animal test subjects with a complex package of human cells.
