...Stem-Cell Breakthrough "Inside the Korean Cloning Lab" [may 30] reported that South Korean scientists have created human stem-cell lines that are perfectly matched to the dna of human patients. That story gave me mingled feelings of delight and worry. Although the whole world is now one step closer to an ideal situation for studying how diseases develop, I worry about whether the U.S. can maintain its scientific and technological superiority. Many other countries have been vigorously pursuing stem-cell projects, while the U.S. government restricts the research that federally funded scientists may do in that field. I hope...
...1/10 of 1¢ today, researchers are doing more all the time. Although 99% of the planet's genomes have yet to be decoded, researchers have identified hundreds of thousands if not millions of genes, dwarfing the paltry 24,000 or so we carry in our DNA...
...also sampling the air over New York City, and other scientists are looking into hot springs, digging into the ground and even testing toxic-waste sites. "You can pick up a gram of soil," says Aristides Patrinos, who oversees the Department of Energy's genome program, "and there's DNA in it. By sequencing that DNA, you can infer what's there in terms of diversity." As a rule, the more diverse a given ecosystem--the more genes present, even at the microbial level--the more resistant it is to damage...
...industry argues that targeted species have recovered to the point where sustainable whaling is possible, and that the country shouldn't feel constrained by foreign sensitivities. "For Japanese people, whale is part of our food culture," says Keiichi Nakajima, president of the Japan Whaling Association. "It's in our DNA...
