...middle-aged men, who (according to the company) begin to emit odors. But by the time we die, or shortly thereafter, the expansion of youth and the postponement of old age may become one of the greatest enterprises of the 21st century. "I see it as inevitable," says evolutionary biologist Michael Rose, who breeds strains of long-lived flies in his laboratory at the University of California at Irvine. "I'm confident that Benzer's work--and the worm people's and maybe my work--will someday be used by a bunch of avaricious corporations who'll make billions...
...each of which allows it to wreak a different brand of havoc. Some mutations spur rapid growth; others prod nearby blood vessels into sprouting new capillaries; still others send cancer cells out into the bloodstream, where they can seed new tumors. Within 10 years, predicts Robert Weinberg, a cancer biologist at the Whitehead Institute in Cambridge, Mass., "we will analyze the mutant genes and then tailor-make a treatment [for] that particular tumor...
Once cloning loses its stigma, the urge to tinker with the genes of offspring may not be far behind. As Cambridge molecular biologist Graeme Mitchison says, "We can all be beautiful--no baldness, no wimps with glasses, no knobby knees." Olivia Judson, author of a forthcoming book called Dr. Tatiana's Sex Advice for All Creation, begs to differ: "If there is such hostility to genetically modified soya, it doesn't bode well for genetically modified people...
...harvest frozen sperm--provided the mammoth is indeed male--and fertilize a female elephant. Close as the thawed father may be, however, he may not be close enough to produce offspring. "Life isn't something you start and stop like a record," says Ward Wheeler, another biologist at the museum. "It has to go on in continuum...
...those who entered the race was molecular biologist Martin Citron. In 1997, shortly after he moved from Harvard to Amgen, in Thousand Oaks, Calif., he and his team began a long, painstaking elimination process by inserting active human genes, in strings of 100 at a time, into living bacterial cells. When the team found cells making more amyloid protein than might have been expected, it narrowed the strings to 20 genes and repeated the process. Finally, the Amgen team zeroed in on the single gene responsible for producing the extra amyloid. Having found the culprit, the researchers went...
