Babies or parts: What science do we want?

We have come a long way since the 2001 controversy over embryonic stem cell research. Back then, we witnessed heated public debates over whether such research should be federally funded: proponents pointed to possible cures for horrific diseases; opponents pointed to the sanctity of all human life and the danger of a "slippery slope."
Although that debate died down after President George W. Bush's peculiar compromise, whereby federal money was to be used to fund research on 71 already existing embryonic stem cell lines, we suddenly find ourselves at the bottom of that proverbial slope.
