...later. But even when they do, scientists will have to learn how to coax them into producing useful tissues. They'll also have to make certain that both the cloning and the coaxing don't damage the cells in a way that make them not just ineffective but lethal. That's the danger with a different form of stem-cell production, announced this past November, in which skin cells are simply genetically reprogrammed to revert to stem cells. The reprogramming, however, can trigger cancerous growth - so that technique, too, is far from ready for clinical...
While Xu's test may help identify at-risk patients more accurately and earlier, what it won't do is tell patients - or doctors - who's at risk for developing aggressive, life-threatening disease. In fact most prostate cancer cases in the United States never become lethal: 99% of men diagnosed with prostate cancer - the vast majority of whom are over 65 - survive at least five years, according to the American Cancer Society, and many die with the disease, not because of it. Still, prostate cancer does kill some 30,000 men a year in U.S. Learning more about genetic...
...part of a larger team taking a unique approach to studying reverse transcription in hopes that approaching it from the perspective of structural biology—the study of the shape of biological molecules—will provide insights into treating lethal diseases, including AIDS and leukemia...
...impact of drug abuse, NIDA estimates it costs the U.S. $484 billion a year in health care costs, lost earnings, crime and accidents. Complicating the problem, addicts tend to abuse more than one substance at a time - two-thirds of cocaine addicts also use alcohol, for example - a potentially lethal combination that may be increasing in popularity. A 2006 University of Florida study found that deaths from cocaine overdose, which often involved alcohol, increased in Florida from 150 a year in 2000 to 300 in 2005. Researchers hope that addiction vaccines may someday help to reverse those trends, not only...
...Supreme Court is part of this slow-motion shutdown of the death-penalty machine. In recent years the court has banned executions of mentally retarded inmates and of prisoners who committed their crimes as minors. The mere fact that the court is hearing the lethal-injection cases is historic because the institution has always been reluctant to inquire into the business end of the death penalty...
