We are starting to see convergence and cross-talk between stem cell, cancer and aging biochemical research. Many new discoveries have applications in all of these fields, like this one detailed in the New Scientist. A molecule connected with stem cell mobility is present in spreading cancers but not normal adult cells, which may lead to a "magic bullet" cancer cure. Understanding differences between stem cells and adult cells will also ease difficulties in stem cell research. Convergence is a sign of progress: we should welcome all such news.
