...help but suspect, however, that the pool of contenders for the title is relatively small. I’m sure Taft or Lincoln would have enjoyed that kind of street cred and mad props, but when it came to the scientific induction of pluripotent stem cells from adult human fibroblasts, I guess they just couldn’t tear themselves away from getting stuck in bathtubs and freeing slaves (respectively) to log enough hours in the lab or scrape together the bread for clonogenic assays. You snooze, you lose...
...rise with the burgeoning elephant population, he says, and Livingstone is a prime spot for viewing the consequences. Each dusk, when elephant feeding time starts, a voluntary curfew descends on the town. This summer, a few miles from his office, tourists at Victoria Falls watched horrified as an adult animal attempted a new route across the Zambezi River and was swept over the rapids. A short walk upriver, Osborn takes me to meet Catherine Lolozi, 48, whose husband Luwaya Kikomeno, 49, was stripped, disemboweled and tossed into a tree by an elephant as he walked home on a city street...
...scientists have surged ahead of ethicists and politicians in finding ever more clever ways to generate stem cells. But where other breakthroughs relied on using cells from living embryos - tiny bits of inchoate life, fraught with ethical issues - the work by Yamanaka and Thomson sidesteps that abyss by nursing adult cells into a state in which their cellular destiny is yet to be fulfilled. No embryos, no eggs, no hand-wringing over where the cells come from and whether it is ethical to make them in the first place...
...estimated 14% of Americans profess to have no religion, and among 18-to-25-year-olds, the proportion rises to 20%, according to the Institute for Humanist Studies. The lives of these young people would be much easier, adult nonbelievers say, if they learned at an early age how to respond to the God-fearing majority in the U.S. "It's important for kids not to look weird," says Peter Bishop, who leads the preteen class at the Humanist center in Palo Alto. Others say the weekly instruction supports their position that it's O.K. to not believe...
...That's why nearly every major stem cell lab began looking for an alternative approach, the most promising of which was to simply reprogram adult cells without eggs or embryos. "When I started this work, I thought it would be a 20-year, not a few-year problem," says Thomson. But sometimes science can be surprising, and in this case, all it took to accomplish a complex biological time warp was a handful of genes that suppress cells from dividing and maturing...
