Researchers grow brains in the lab to test new drugs

Engadget highlights the development of an alternative to animal testing at Johns Hopkins University: Researchers have developed a method to create mini brains from human stem cells that allow them to test the effectiveness of new treatments for neurological conditions such as Alzheimer’s, Parkinson’s and multiple sclerosis. The approach should lead to more rapid and effective testing of treatments likely to work in humans whilst significantly reducing testing on animals.
