Although embryonic stem cells have certainly grabbed most of the attention - and headlines - in the stem cell field in recent years, embryos aren't the only source of these versatile mother-cells. Political leanings aside, researchers are beginning to appreciate that many tissues in the body have their own stem cells. Blood cells, for example, derive from a single hematopoietic stem cell in the bone marrow, and now two groups of scientists from Boston report that they have identified a similar mother stem cell from which most heart cells arise. Working with mice, one group at Massachusetts General Hospital isolated...
...Democrat on the panel in order to maintain a traditional rotation in the spot. But Democratic insiders say her motivation is far more personal - as was Pelosi's support of Murtha against her nemesis of several years, incoming Majority Leader Steny Hoyer. Harman defenders say Pelosi's complaints either stem from an unworthy catfight among leading California congresswomen; Harman's close relationship with Hoyer; or Harman's efforts to seem bipartisan on controversial issues such as the Administration's controversial domestic warrantless wiretapping - when Pelosi wanted a Democratic pit bull in the party's top intelligence post...
...Minister Barham Salih, a Kurd, hastened to distance the government from the warrant, perhaps mindful of the importance of leaders such as al-Dari for the government to have any real chance at tamping down the insurgency through a political accommodation of the Sunnis. And the government tried to stem the controversy Friday by clarifying that it had only issued an investigation warrant, not an arrest warrant; one official insisted that Prime Minister Nouri al-Maliki didn't know that any warrant was going to be issued. But the damage has already been done. It didn't help matters that...
...example, researchers of the phenomenon of genocide will never really be able to understand what happened in Rwanda unless they analyze sociology and psychology along with history and political science. Likewise, the Harvard Stem Cell Institute brings together lawyers and public policy experts with geneticists and biologists. The benefits of interdisciplinary research have all been widely noted, but Hyman—and the Task Force on General Education—took it a step further when they emphasized interdisciplinary teaching in undergraduate liberal education...
...actually a pair of millionaires interested in getting themselves some tax cuts. Maybe those traditional Christians that you see at the Democratic National Convention aren’t godless, but have a family member suffering from Parkinson’s disease and can see the potential benefits of stem-cell research. Ultimately, when these people flout the expectations of our culture, they acknowledge that there is in fact more than one aspect of their identity or lifestyle that’s important to them...
