...private research had produced a trove of more than 60 stem-cell lines. Most experts had assumed that there were as yet only a dozen or so such colonies of the cells that might become weapons against a range of debilitating diseases, from Alzheimer's to juvenile diabetes to Parkinson's. The vastly larger number was enough, Bush said, to "explore the promise and potential of stem-cell research"--and, not incidentally, enough to give him room for a politically palatable compromise on the question of federal funding. But last week came another surprise, when the National Institutes of Health...
...nearly everyone agrees on one thing: stem cells, the unspecialized cells the body uses as raw material for tissues and organs, have the potential to treat an astonishing range of ills, including Parkinson's disease, diabetes, Alzheimer's and spinal-cord injuries. After Bush's decision, the question becomes whether they'll ever get a fair chance...
...stem-cell research. ("Scared me to death," he says.) So far, he has sold embryonic stem cells (at $5,000 for two vials) to some 30 research groups. Though he believes stem cells may someday be used to replace the faulty cells at the root of diseases like Parkinson's, he sees a more fundamental and perhaps more important role for them: explaining why some cells grow up healthy while others get sick and die. "We are simply ignorant about very early development," he says...
...thread of an argument while we are trying to make a point. A brain without working memory is like a computer without its RAM; its computational abilities are crippled, as they often are in people with diseases that affect the frontal lobe, such as cerebral palsy, dementia, Alzheimer's, Parkinson's and schizophrenia...
...Rakic's best efforts, there is still probably as much we don't know about the frontal lobe as we do. But she has helped open the door wider for other scientists to explore, and given hope and new ideas to researchers studying various conditions--from drug abuse to Parkinson's--that affect memory. Psychologists in particular respect Goldman-Rakic for the way she is constantly trying to bring psychology and biology closer together--thinking about the mind as a whole even while she is looking through a microscope...
