...that's just the beginning. Someday, scientists hope to use cells like these to cure diabetes, Parkinson's disease and multiple sclerosis, as well as to reverse congestive heart failure and heal spinal-cord injuries. But there are some aspects of this story that are brave new world-ish. Known scientifically as stem cells, Pedersen's marvelously pliable cells are derived from seven-day-old human embryos, which are destroyed in the process. Although not all stem cells are produced this way, embryonic stem cells seem for now to have the greatest potential for medical miracles...
...average Americans heading as high as 75 to 80 years, it is our responsibility to do everything possible to protect the quality of life of the present and future generations. A critical factor will be what we do with human embryonic stem cells. These cells have the potential to cure diseases and conditions ranging from Parkinson's and multiple sclerosis to diabetes and heart disease, Alzheimer's, Lou Gehrig's disease, even spinal-cord injuries like my own. They have been called the body's self-repair...
Treatment with stem cells has already begun. They have been taken from umbilical cords and become healthy red cells used as a potential cure for sickle-cell anemia. Stem-cell therapy is also being used against certain types of cancer. But those are cells that have significantly differentiated; that is, they are no longer pluripotent, or capable of transforming into other cell types. For the true biological miracles that researchers have only begun to foresee, medical science must turn to undifferentiated stem cells. We need to clear the path for them as rapidly as possible...
...received FDA approval for the first completely new type of antibiotic in more than 35 years. The medication comes as a welcome weapon in the war on "superbugs," mutated bacteria that, over the generations, have grown immune to the old-standby antibiotics. The new drug, Zyvox, is not a cure-all - it attacks only certain forms of bacteria - but in tests it cured two thirds of the patients with strains of staph that are immune to the strongest antibiotics currently available. But although there is hope that Zyvox can put a halt to the mutation process - by blocking growth much...
...parents or school officials. Supporters of the notification process want the information to be made as widely available as possible - advocating, for instance, its posting on the Internet. They also point out that the psychosexual impulses that lead people to commit sex offenses against children are very difficult to cure or suppress, leading to a high rate of repeat offenses. The defenders argue that by serving their sentences the offenders have, in effect, paid their debt to society. They also make the case that wide distribution of personal information such as pictures and addresses could lead to acts of retribution...
