Scientists have been exploring alternatives to the traditional—but harmful—retrovirus approach since researchers first reprogrammed human skin cells with the method late last year. Integrating these viruses into the cells' DNA causes permanent genetic manipulation, which can trigger malignant tumor growth, making them unsafe for human use. Scientists ultimately hope to clear this hurdle and treat a wide variety of human diseases by transplanting body tissues created from stem cells. Only three weeks ago, Harvard Medical School professor Konrad A. Hochedlinger and his colleagues at HSCI reported that they created mouse iPS cells using harmless...

...unclear how much vitamin D kids really need. It depends on a host of factors: children with epilepsy, cystic fibrosis or celiac disease may need more than the 400 IUs the AAP is recommending; kids with darker skin or living at northern latitudes with less sun may also require more. That means, of course, parents should consult their own pediatrician about how much vitamin D to give, but says Gordon, "Vitamin D toxicity doesn't occur until at least 2,000 IU a day and maybe as high as 10,000, so they shouldn't be overly worried about giving...
...trip took me several times across the wide, brown Missouri River, and it occurred to me that these issues of skin color and tribe have haunted these parts at least since Lewis and Clark paddled the liquid highway westward. But as I listened to voters, what became clear was that the Obama campaign is not the simple racial referendum some commentators have pictured. I heard several reasons why voters might be reluctant to support the guy, but race was rarely cited...
...don’t,’” Apfelbaum said. “We know that infants as young as six months can discriminate between different races, yet children eventually come to the conclusion that using this principle to describe people based on skin color is inappropriate, even when it is helpful information.” The researchers based their study on the board game “Guess Who?” The players were presented with a set of pictures and asked questions to determine the randomly-chosen picture of the other player...
