Solving damage done to hearts and pulling cells from bodies one by one

I found this of interest today:

Canadian researchers, for the first time, have developed an organic substance (scaffold) that attracts and supports cells necessary for tissue repair and can be directly injected into problem areas.Find Me A Cure, Jan 2009

In a similarly telling story, Johns Hopkins (my alma mater) is reporting dust-sized robotic specs that can clean various types of cells from the body.

This research offers future prospects of saving many thousands who now die of heart failure with a relatively simple stem-cell related technology. It is increasingly important to begin the process of thinking about governance as major disease vectors or aging begin to be radically addressed in the near term.  This will change all manner of social calculations and will, most likely, require very different resource allocation paradigms.
