Betterhumans talks about recent work on a new way to help the brain regenerate damage from stroke or neurodegenerative disorders such as Alzheimer's, Parkinson's and Huntington's disease. This is comparatively low-tech - simply blocking a key chemical involved in regulating neural growth - and is not a path to real cures. However, researchers would not be able to make this leap without the tremendous advances in medical technology and biochemistry over the past decade. The more we learn, the more we can do. Articles like this are very encouraging.
