...story is more complex: Kenyon has found that hormones in her long-lived worms actually regulate several unusual genes to increase life-span. One set of genes triggers the worms' cells to make antioxidants, which fight off the ravages of molecules called free radicals, which can damage DNA. Another set directs the creation of proteins called chaperones; they help other proteins fold into their proper shapes. They also detect and destroy improperly folded proteins that can cause such aging-related ailments as Huntington's disease. Other genes affect the transport of fat around the body--which may also have...
...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 win by Fani Halkia and a fourth...
...seems. The accent tumbles out of bars and restaurants; crowds of Aussies with tell-tale stripes of sunblock saunter around the dusty futuristic vastness of the Olympic complex. Everyone here points out that Melbourne's Greek population makes it the third biggest Hellenic city after Athens and Thessaloniki; it seems possible that this week Athens could just pip Brisbane in the Aussie population rankings. Nowhere is more Australian than the aquatic center this first Monday of competition. From the top of the stand the view stretches back across the city, white against the dull brown hills...
...find Kim Hyung Gyoon's office in Samsung's R.-and-D. complex, just follow the baskets of dirty clothes. No, Kim is not running the company Laundromat. As chief of Samsung's washing and cleaning technology group, he is the man behind a new washing machine that deposits tiny silver particles--about 11/410,000 the thickness of a human hair--onto clothes to make them bacteria-and odor-free without the use of hot water. The device represents the first mass-produced application of this type of nanotechnology--the science of very small structures--to home appliances...
...only 15%--had a choice: export or go bust. "We had to differentiate ourselves," says Bernardo Hoffmann, marketing director for the Wines of Argentina export association. Hence the rebirth of Malbec, a French migrant long dissed as merely a blending grape. Enologists found the grape to be a more complex varietal than once thought, especially in Mendoza's dryer, Andean conditions. Today, Malbecs like Catena's, from $10 to $50, score high with U.S. critics for their exuberant, fruity and floral styles. "We're aiming for the 25-to-40-year-old market," says Catena in his state...
