...Think diet soda helps you lose weight? Think again. According to a study in the International Journal of Obesity, artificially sweetened, low-calorie foods can thwart your ability to regulate how much you eat?if you are a rat, that is. Researchers found that lab animals sometimes fed saccharin-sweetened liquid consumed more food than did rats given an equally sweet but always high-calorie liquid. (Rats given a high-cal supplement the consistency of milk also gained more weight than did rats fed a thicker, pudding-like substance.) The study's authors think the same phenomenon may hold true...
...full. Translation: they eat only to the point at which they are about 80% sated. That makes for a daily intake of no more than 1,800 calories, compared to the more than 2,500 that the average American man scarfs down. And as scientists have learned from lab animals, the simple act of calorie restriction can have significant effects on longevity...
...that severely restricting calorie intake can slow down the aging process. Evidence for that surprising phenomenon emerged in the 1930s, when scientists learned that underfed rodents lived up to 40% longer than their well-fed counterparts. The results have since been duplicated in fruit flies, worms, monkeys and other lab animals. And preliminary research on humans suggests that some markers of aging--levels of blood glucose, blood pressure, cholesterol--improve on calorie-restriction (CR) diets...
...sports, from boxing to track and field to weight lifting, were thrown out of the Games for doping-related transgressions, the most in Olympic history. But antidoping officials saw the high toll as progress in their fight to clean up sports. Said Costas Georgakopoulos, who runs the doping lab at the main Athens Olympic complex that analyzed about 3,000 urine and blood samples during the Games: each positive "means we're successful." In the end, the host nation could say the same. Greece ended with a sparkling medal haul that included a dominant 400-m women's hurdles...
...will be much harder to track than a synthetic steroid like andro or a stimulant like ephedrine. That's because compounds delivered directly to muscle generally remain corralled there, rarely reaching the bloodstream or urine, where they could be traced. Though genetic treatments are not yet out of the lab, WADA has enlisted the help of researchers who have provided them with ideas for identifying competitors taking advantage of the new therapies. (Here's a hint: start with the record breakers.) "I don't think anyone will be competing in Athens with genetic enhancement," says Dr. H. Lee Sweeney, chairman...
