Using a very roundabout technique, scientists have created mice with two genetic fathers. But don’t look for this to be applicable any time soon with humans. The convoluted technique needs flow charts to explain (thankfully provided by the authors in their paper.)
While the subject of cloning has not been in the news lately, people should realize that there are some scientists who still want human clones, and politicians pushing for approval of human cloning for experiments.
Scientists at McMaster University in Canada have shown that they can transform human skin cells directly into blood cells, without going through an intermediate stem cell stage.
The media have rarely reported on the multitude of successes with adult stem cells in the past, preferring to focus on unethical, unsuccessful embryonic stem cells. So it was heartening to see Malcolm Ritter and the Associated Press put out a story that highlights some of the real successes and promise of adult stem cells, as opposed to the wishful thinking and hype of embryonic stem cells.
