...genome as a whole, scientists can begin addressing broader questions about who we are and how we got here. They're learning, for example, that humans have far fewer genes than the 100,000 to 140,000 scientists believed as recently as last summer. The real count, says Celera geneticist Mani Subramanian, turns out to be more like 30,000 or 35,000--a number that seems shockingly low to many scientists. "We think we're superior beings," he says. "But we have the same number of genes as a plant...
...author of an earlier book on human sacrifices among the Inca, spent 11 years researching the Yanomami's exposure to the outside world. In his most hotly contested charge, he claims that during a research project funded by the U.S. Atomic Energy Commission, the late James Neel, a human geneticist at the University of Michigan, used a measles vaccine on the Yanomami that helped spread an epidemic, killing "hundreds, perhaps thousands" in a population of roughly...
Enough with the hackneyed song-and-dance routine about genetically modified crops being designed to feed the poor and nourish the hungry [SCIENCE, July 31]. As one geneticist has put it, "The gene revolution, like the green revolution, is more likely to feed company pockets than the world's population." TERRANCE DOUGLAS West Vancouver...
...onset Alzheimer's, while rare, often ran in families. Could it be, they wondered, that the culprit was a mutant version of the APP gene? In 1991 scientists at London's St. Mary's Hospital Medical School screened the DNA of an Alzheimer's family and found what every geneticist in the field had been furiously looking for. The mutant APP gene sat on chromosome 21, and the single change in its DNA sequence occurred in the vicinity of the beta-amyloid fragment...
...APOE4 may contribute to the development of more than 60% of all late-onset Alzheimer's cases. But that leaves the other 40% unaccounted for. And at this moment, many scientists, including Roses, are racing to identify still other Alzheimer's-susceptibility genes. Rudolph Tanzi, a geneticist from Harvard, believes that he has nabbed a prime suspect on chromosome 12, a gene called A2M. But he has yet to convince his critics. Two years ago, when Tanzi presented his data at an Alzheimer's meeting in Amsterdam, his evidence was brutally attacked. "I wish I'd been wearing chain mail...
