Dr. Stephen Sullivan of Rockefeller University, New York, discusses the special characteristics of stem cells, what the different types of stem cells are, and how each type is being used to treat human disease.
 Dr. Sullivan will highlight common mistakes concerning stem cells in the media and will highlight the broader problem of the decline of fact based science journalism and the rise of unsubstantiated blogging and the particular problem this represents for medical decision making generally, and those involving stem cell therapy in particular.
