单选题{{B}}Text 2{{/B}} It is a wise father that knows his own child, but today a man can boost his paternal (fatherly) wisdom— or at least confirm that he's the kid's dad. All he needs to do is shell out $30 for paternity testing kit (PTK) at his local drugstore—and another $120 to get the results. More than 60,000 people have purchased the PTKs since they first became available without prescriptions last year, according to Doug Fogg, chief operating officer of Identigene, which makes the over-the-counter kits. More than two dozen companies sell DNA tests directly to the public, ranging in price from a few hundred dollars to more than $ 2,500. Among the most popular: paternity and kinship testing, which adopted children can use to find their biological relatives and families can use to track down kids put up for adoption. DNA testing is also the latest rage among passionate genealogists—and supports businesses that offer to search for a family's geographic roots. Most tests require collecting cells by swabbing saliva in the mouth and sending it to the company for testing. All tests require a potential candidate with whom to compare DNA. But some observers are skeptical. "There is a kind of false precision being hawked by people claiming they are doing ancestry testing," says Troy Duster, a New York University sociologist. He notes that each individual has many ancestors—numbering in the hundreds just a few centuries back. Yet most ancestry testing only considers a single lineage, either the Y chromosome inherited through men in a father's line or mitochondrial DNA, which is passed down only from mothers. This DNA can reveal genetic information about only one or two ancestors, even though, for example, just three generations back people also have six other great-grandparents or, four generations back, 14 other great-great-grandparents. Critics also argue that commercial genetic testing is only as good as the reference collections to which a sample is compared. Databases used by some companies don't rely on data collected systematically but rather lump together information from different research projects. This means that a DNA database may have a lot of data from some regions and not others, so a person's test results may differ depending on the company that processes the results. In addition, the computer programs a company uses to estimate relationships may be patented and not subject to peer review or outside evaluation.

单选题Why we age is the subject of vigorous debate. The classical view is that aging happens because of random wear and tear. A newer view holds that aging is more orderly and genetically driven. Proponents of this view point out that animals of similar species and exposure to wear and tear have markedly different life span. The Canada goose has a longevity of 23. 5 years; the emperor goose only 6. 3 years. Perhaps animals are like plants, with lives that are to a large extent, internally governed. Certain species of bamboo, for instance, form a dense stand that grows and flourishes for a hundred years, flowers all at once, and then dies. The idea that living things shut down and not just wear down has received substantial support in the past decade. Researchers working with the now famous worm C. elegans(two of the last five Nobel Prizes in medicine went to scientists doing work on the little nematode)were able to produce worms that live more than twice as long and age more slowly by altering a single gene. Scientists have since come up with single-gene alterations that increase the life spans of Drosophila fruit flies, mice and yeast. These findings notwithstanding, scientists do not believe that our life spans are actually programmed into us. After all, for most of our hundred-thousand-year existence—all but the past couple of hundred years—the average life span of human beings has been thirty years or less.(Research suggests that subjects of the Roman Empire had an average life expectancy of twenty-eighty years.)Today the average life span in developed countries is almost eighty years. If human life spans depend on our genetics, then medicine has got the upper hand. We are, in a way, freaks living well beyond our appointed time. So when we study aging, what we are trying to understand is not so much in a natural process as an unnatural one. Inheritance has surprisingly little influence on longevity. James Vaupel, of the Max Planck Institute for Demographic Research, in Rostock, Germany, noted that only six percent of how long you"ll live, compared with the average, is explained by your parents" longevity; by contrast, up to ninety percent of how tall you are, compared with the average, is explained by your parents" height. Even genetically identical twins vary widely in life span: the typical gap is more than fifteen years.

单选题Chinese firms are going global for the usual reasons: to acquire raw materials, get technical know-how and gain access to foreign markets. But they are under the guidance of a state that many countries consider a strategic competitor, not an ally. As our briefing explains, it often appoints executives, directs deals and finances them through state banks. Once bought, natural-resource firms can become captive suppliers of the Middle Kingdom. Some believe China Inc can be more sinister than that; for example, America thinks that Chinese telecoms-equipment firms pose a threat to its national security. That would be a mistake. China is miles away from posing this kind of threat: most of its firms are only just finding their feet abroad. Even in natural resources, where it has been most active in dealmaking, it is not close to controlling enough supply to rig the market for most commodities. Nor is China"s system as monolithic as foreigners often assume. State companies compete at home and their decision-making is consensual rather than dictatorial. When abroad they may have mixed motives, and some sectors—defence and strategic infrastructure, for instance—are too sensitive to allow them in. But such areas are relatively few. What if Chinese state-owned companies run their acquisitions for politics, not profit? So long as other firms could satisfy consumers" needs, it would not matter. Chinese companies could safely be allowed to own energy firms, for instance, in a competitive market where customers could turn to other suppliers. And if Chinese firms throw subsidised capital around the world, that"s fine. America and Europe could use the money. The danger that cheap Chinese capital might undermine rivals can be better dealt with by beefing up competition law than by keeping investment out. Not all Chinese companies are state-directed. Some are largely independent and mainly interested in profits. Often these firms are making the running abroad. Take Volvo"s new owner, Geely. Volvo should now be able to sell more cars in China; without the deal its future was bleak. Chinese firms can bring new energy and capital to flagging companies around the world; but influence will not just flow one way. To succeed abroad, Chinese companies will have to adapt. That means hiring local managers, investing in local research and placating local concerns—for example by listing subsidiaries locally. Indian and Brazilian firms have an advantage abroad thanks to their private-sector DNA and more open cultures. That has not been lost on Chinese managers.
