These webcasts and presentations, like the presentation by Dr. List, provide good overviews.
If you want to keep up with ongoing medical news,
The MDS Foundation and the
Aplastic Anemia & MDS International Foundation both have newsletters with articles that we laypeople might actually understand.
Although they tend to be more technical, I'd also recommend the National Institutes of Health's
PubMed website (you'll have to search for MDS articles) and the
The MDS Beacon website (which specializes in MDS news).
