http://story.news.yahoo.com/news?tmpl=story&u=/nm/20030124/sc_nm/health_australia_superman_dc_3 The big controversy isn't really whether it's being done on humans - eventually, research must move from nonhuman animals to humans. The controversy is the fact it's being done with embryonic stem cells. Isn't that wild?! I still do not know how I feel about embryonic stem cells being used to grow new parts for people, but I do know that adult stem cells (found in places like the pancreas) aren't as effective, nor do they respond to stimulants quite like embryonic stem cells. I am eagerly awaiting the results of these human tests.
