Science does good...

This would make Aristotle happy, since he claimed that all, to include science, is naturally directed toward the good.

From Science:

Scientists this week reported major advances toward a central goal of stem cell research: directly reprogramming fetal mouse cells so that they are indistinguishable from embryonic stem (ES) cells. The technique, which they say should also work on adult cells, could one day enable researchers to generate cell lines tailored to individual patients without the use of eggs or embryos.

Thus, while experimenting on ES make me and many others very uncomfortable, we can hope that the controversy surrounding research on ES cells with become a non-issue. So, hurray for scientists!
