From the Wall Street Journal:

Lost amid the veto politics this week was the fact that Congress also moved in other ways on ethics and medical research. Mr. Bush signed a bill passed unanimously by the House and Senate that outlawed "fetal farming," or the practice of raising and aborting fetuses for scientific research. The Senate also passed legislation that would have encouraged greater research into exploiting the stem cells scientists need without destroying embryos, as well as research into adult stem cells. That bill failed in the House, mainly because Democrats think they can use stem cells as a political issue against Republicans this fall.

The bill, S. 2754, passed the Senate unanimously, but for some reason needed a two-thirds vote to suspend the rules and pass the bill in the House. The vote was 273-154, with nearly all Republicans voting in favor, and two-thirds of the Democrats voting against.

Only stem cells from non-embryonic sources have found therapeutic uses. Pro-Life Blogs has a list of recent stories about adult stem-cell breakthroughs.
