If you like reading about medical science and research, let me recommend you this interesting lecture about stem cell research written by dr Christopher Centeno: The Stem Cells they Don’t Want You to Have: How the New Stem Cell Debate Will Shape the Future of Medicine The book is free to download, at least for now. I know the title might sound a bit conspiracy theory-ish but dr Centeno makes some really good points Long story short, we live in very exciting times. The whole new field of medicine is right behind the corner but is effectively suppressed by the "big players". That's because stem cell treatments would gradually replace conventional drugs used nowadays and bring great losses to pharma companies in result. Stem cells are not decades away really. There's been some excellent results in treatments on animal models and to a limited degree on humans. If only we had a "green light" from FDA, stem cell treatments would become a standard in around 10 years from now.
