...basic information about where the sisters were born, who their parents and siblings were, and why each one decided to join the order. With these documents, moreover, Snowdon now had an objective measure of the sisters' cognitive abilities while they were still young and in their prime. An epidemiologist could not have designed a better way to evaluate them across time. "For many years," says the National Institute's Suzman, "we had an inadequate sense of how connected late-life health, function and cognition were to early life. But in the past decade, spurred by the Nun Study, there...
Until then, whenever any new study--like the ovarian-cancer report--comes along, you have to consider it as part of the larger picture. The first thing you must realize, says Dr. Carmen Rodriguez, a senior epidemiologist at the American Cancer Society who led the study, is that a woman's chances of dying from ovarian cancer are pretty low--about 1.7% over the course of her lifetime. Twice a low risk is still a low risk. (Study participants who took estrogen actually lived longer than those who didn't--partly because such volunteers often live healthier lives and have...
...microbes that cause such diseases as TB and malaria will never stop evolving, warns Columbia University epidemiologist Dr. Stephen Morse, and they will develop resistance to the next generation of miracle drugs just as they did in the past. How fast they do so is in large part up to us. With antibiotics, too little is not a good thing, observes Morse, and neither is too much. Unless we devise a formula that is just right, he predicts, we will forever be frantically racing to catch up with our nimbler microbial foes...
...food chain--specifically, DDE, a breakdown product of the pesticide DDT, and PCBs, once used as flame retardants in electrical equipment. Both chemicals are plausible suspects because they mimic hormones that play a key role in the development of the reproductive system. Beyond that, says Dr. Walter Rogan, an epidemiologist at the National Institute of Environmental Health Sciences in Research Triangle Park, N.C., both chemicals are ubiquitous in the environment, and they persist in the body for years after exposure...
...Epidemiologist Charles Yesalis of Penn State, an expert on performance enhancers, says new I.O.C. testing for EPO is "fluff," that it won't detect athletes who quit taking the drug a week or so before the Games...
