...recommendations should be applied only to American patients, the IOM says. Although the guidelines use globally accepted BMI cutoffs determined by the World Health Organization to define pre-pregnancy obesity, the weight-gain recommendations may not be appropriate for women in other countries, who are shorter or thinner or have inadequate prenatal care...
Stem-cell science is a fast-moving field. Just three years since a Japanese researcher first reprogrammed ordinary skin cells into stem cells without the use of embryos, scientists at a Massachusetts biotech company have repeated the feat, only this time with a new method that creates the first stem cells safe enough for human use. The achievement brings the potentially lifesaving technology one step closer to real treatments for disease...
Still, the rapid pace of the research means we may not have to wait long. "We really lucked out," says Lanza. "These iPS cells were just discovered a few years ago, and here we are three years later with a method safe enough to actually use in people." ACT plans to file a request for the first human trial using its cells sometime next year...
...Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins. The innovation builds on the breakthrough discovery in 2006 by Shinya Yamanaka, who similarly coaxed human skin cells to revert to a pristine, embryonic state by introducing four key genes into the cells, piggybacked on viruses. However, some of those genes are known to cause cancer, which made Yamanaka's stem cells - known as induced pluripotent stem cells, or iPS cells - unsuitable for human use.

...findings may herald a practical solution to the problem of embryonic stem cells, the controversial cells that can be derived only from embryos (researchers currently use embryos that have been discarded during fertility treatments). President Obama recently lifted the long-standing ban on federal funding of human-embryonic-stem-cell research, but still, these stem cells are unlikely to prove useful as human treatments - for maladies like diabetes, Parkinson's or spinal-cord injuries - since they would not be tissue-matched to the individual patients who need them. The new method could allow scientists to create stem cells using...
