Stem cell research
Stem cell research offers the hope of curing many serious diseases including Parkinson but some types of stem cell treatment destroy human embryos. Christians tend to think that a ball of cells without feelings counts for more than a dsuffering human being. Under George W. Bush stem cell research got no public funding in the United States. The main effect of the ban was that in this one area other nations were getting ahead of the United States. Obama has reversed the ban and the United States is now working hard to catch up with those other countries. They call it making up for lost time.
