...hands can be fraught. Wikipedia founder Jimmy Wales was notoriously outed in 2005 for attempting to whitewash his own entry on the site (Wiki contributors noted that he deleted references to his Wikipedia co-founder, Larry Sanger, as well as to a search site he founded that included adult content). Now a monitoring program called WikiWatcher aims to unmask similar transgressions on other Wiki entries - such as when ExxonMobil tried to downplay the environmental impact of the Valdez oil spill and when the FBI deleted aerial images of the Guantánamo Bay detention camp from the camp's entry...
...cautionary tales. Most Democrats, and some Republicans, have pushed for full federal funding of embryonic-stem-cell research, an issue so hot it tipped some close 2006 midterm races. But since then, the biggest breakthroughs have come in techniques that do not use embryos at all but instead reprogram adult cells. Do proponents look reckless for putting all their emphasis on embryos, which even some prominent scientists find morally troubling? Or prescient, because the basic knowledge gleaned from embryo research is what may help make it unnecessary someday...
...outright ban on all embryo research, public or private. Meanwhile, a McCain-Palin ad lauds the pair as the "original mavericks" for supporting "stem-cell research to help free families from the fear and devastation of illness." But that's not courage; it's camouflage. Everyone favors adult-stem-cell research: the only fight is over experiments that destroy embryos...
...years ago, Ruvkun and Ambros, then fellows working in the laboratory of MIT professor H. Robert Horvitz, began studying the genes that control the development of the Caenorhabditis elegans, a 1 mm-long roundworm that biologists often use as a model organism, from newly-hatched larva to fully-grown adult...
...HSCI co-director Douglas A. Melton is the first to report successful “direct reprogramming,” a technique that, as its name suggests, directly transforms one type of a fully formed adult cell into another...
