...nonsense coach he is. Consider, for example, Step 5, which posits that many ideas fail to amount to much in the end because their creators don't bother to do any research on who else has already tried something similar and then what roadblocks they ran into. Ignoring the work of others, Sindell says, is a form of laziness hidden behind "the metaphor trap of 'not reinventing the wheel.' In reality, the wheel gets reinvented all the time because we need an almost infinite variety of wheels. The gear was a reinvention of the wheel, as was the pneumatic tire...
...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...
...Arnold Kriegstein, director of the Institute for Regeneration Medicine at the University of California, San Francisco, is excited by the advance but notes that it is still relatively inefficient. "The ability to make cell lines from patients with any risk of genetic alteration is a significant step, but the efficiency of 0.001% of cells is low, and even that took two months to achieve," he says, referring to the fact that only a tiny percentage of skin cells in the study transformed into iPS cells over two months. "How readily or quickly this technology is applied, and whether the efficiency...
...dish. "We don't know if iPS cells can do everything that normal human embryonic stem cells can do," says Lanza. "There are certainly a lot of questions we still have to answer." But having a population of stem cells that are safe for human use is an important step toward finding some of those answers...
Last year, Rajendra Pachauri, chairman of the U.N. Intergovernmental Panel on Climate Change, suggested that the most useful step ordinary citizens could take to help combat climate change would be to stop eating meat. In Belgium, an entire town is taking his advice to heart. The Flemish city of Ghent has designated every Thursday as "Veggiedag" - Veggie Day - calling for meat-free meals to be served in schools and public buildings, and encouraging vegetarianism among citizens by promoting vegetarian eateries and offering advice on how to follow a herbivorous diet...
