Progress towards complete understanding and control of our cells continues, step by step. The Independent reports on the latest new research: "Scientists have grown fully mature brain cells in a laboratory for the first time, using a technique that mimics the natural process of brain regeneration. It promises to open the door to new ways of treating and possibly curing debilitating brain diseases such as Parkinson's, epilepsy and Alzheimer's. ... Now we can make a lot of brain cells from just a very small number of these stem cells, which is great because we'd have to do that to repair neurological disease. ... The home run is that we will find drugs to mobilise our own population [of brain stem cells]."
