Some interesting basic research on mechanisms of degenerative diseases is reported at EurekAlert. While one should always take such early-stage research with a grain of salt, it raises the possibility of a single therapy that would be effective against Alzheimer's, Parkinson's, Huntington's, type II diabetes and CJD. Most of these are age-related conditions and all cause great suffering. Whole-body and brain degenerative conditions are of great concern to people who practice healthy life extension: organ replacement or other near-term regenerative medical breakthroughs are not effective treatments. Research on underlying causes and work towards effective therapies is therefore of great importance.
