单选题 {{B}}How to live to 100{{/B}} A growing body of research suggests that chronic illness is not an inevitable consequence of aging, but more often the result of lifestyle choices. "People used to say, 'who would want to be 100?'" says Dr. Thomas Perls, an instructor at Harvard Medical School and director of the New England Centenarian Study. "Now they' re realizing it' s an opportunity." High-tech medicine isn't likely to change the outlook dramatically; drugs and surgery can do only so much to sustain a body once it sr. arts to fail. But there is no question we can lengthen our lives while shortening our deaths. The tools already exist, and they're within virtually everyone's reach. Life expectancy in the United States has nearly doubled since a century ago—from 47 years to 76 years. And though centenarians are still rare, they now constitute the fastest-growing segment of the U.S. population. Their ranks have increased 16-fold over the past six decades—from 3,700 in 1940 to roughly 61,000 today. The Census Bureau projects that 1 in 9 baby boomers (9 million of the 80 million people born between 1946 and 1964) will survive into their late 90s, and that1 in 26 (or 3 million) will reach 100. “A century ago, the odds of living that long were about one in 500," says Lynn Adler, founder of the National Centenarian Awareness Project and the author of "Centenarians: The Bonus Years." "That's how far we've come." If decrepitude were an inevitable part of aging, these burgeoning numbers would spell trouble. But the evidence suggests that Americans are living better, as well as longer. The disability rate among people older than 65 has fallen steadily since the early 1980s, according to Duke University demographer Kenneth Manton, and a shrinking percentage of seniors are plagued by hypertension, arteriosclerosis and dementia. Moreover, researchers have found that the oldest of the old often enjoy better health than people in their 70s. The 79 centenarians in Perls's New England study have all lived independently through their early 90s, taking an average of just one medication. And when the time comes for these hearty souls to die, they don't linger. In a 1995 study, James Lubitz of the Health Care Financing Administration calculated that medical expenditures for the last two years of life—statistically the most expensive—average 22,600 for people who die at 70, but just ＄8,300 for those who make it past 100. These insights have spawned a revolution in the science of aging. "Until recently, there was so much preoccupation with diseases that little work was done on the characteristics that permit people to do well," says Dr. John Rowe, the New York geriatrician who heads the MacArthur Foundation's Research Network on Successful Aging. Research confirms the old saying that it pays to choose your parents well. But the way we age depends less on who we are than on how we live—what we eat, how much we exercise and how we employ our minds.

单选题For most of the past three years, the highly pathogenic bird flu known as HSNI has been found mainly in Asia. Suddenly it has arrived in many countries in Europe, triggering widespread alarm. The detection of the virus in wild birds across Europe is certainly a cause for concern, particularly to Europe's poultry farmers, who are rightfully worried that the presence of the virus in wild birds will increase the risk to their flocks. However, in the midst of a European debate about the benefits of vaccinating chickens and whether or not poultry should be brought indoors, there is a danger that far more significant events elsewhere will be overlooked. In particular, most attention should be focused on the fact that bird flu is now widespread in the poultry flocks of two nations in Africa—Egypt and Nigeria—and in India. And on the fact that, in Nigeria, the disease is continuing to spread despite great efforts undertaken by the government. An outbreak in Afghanistan also appears to be inevitable. Arguably, these matter much more than the arrival of the disease in Europe. Poor countries with large rural populations are in a far weaker position to handle, and stamp out, outbreaks of bird flu in poultry, through both culling and the prevention of the movement of animals in the surrounding areas. In Africa and India, chickens and ducks are far more likely to be found roaming in people's backyards, where they can mingle with humans, other domestic animals and wildlife, thus spreading the disease. In Europe, by contrast, most poultry are kept in regulated commercial farms. The opening up of a new African front for the bird-flu virus is a problem because eradication there will be tremendously difficult. There is a high risk that the disease will spread to other countries on the continent and it could easily become endemic—as it has in Asia. This offers the virus huge new scope to mutate and become a disease that can pass between humans. The virus is certainly mutating—genetic changes have already affected its biological behavior, although apparently not yet its transmission between humans. Experts are unsure as to how much, and what kind, of genetic changes would be required for the virus to become a global health threat. Nor do they know how long this process might take. But to dwell on the increased risk of a pandemic of influenza is to miss a serious point about the direct risks posed by the loss of a large numbers of chickens and ducks across Africa. For some time, the United Nations Food and Agriculture Organization has been warning that if avian flu gets out of control in Africa, it will have a devastating impact on the livelihoods of millions of people. Poultry is a vital source of protein. For example, it provides almost 50% of the protein in the diet of Egyptians. The spread of a disease that is highly lethal to poultry, and requires culling, could have a dire nutritional impact, there as elsewhere. Africa would also have to contend with huge economic losses. People who scratch out a living in poor African nations simply cannot afford to lose their chickens. Most of the world's poor live in rural areas and depend on agriculture. In Africa, rather, a lot of these poor people depend heavily on their poultry. It is easy to see why some believe that bird flu could turn out to be primarily a development—rather than just a health-issue for the whole African continent. What can be done? It is clear that the movement and trade of poultry is making a big contribution to the spread of the virus. That trade needs tighter regulation, as does the movement of live birds from countries with HSN1 infections. In such places trade should be suspended until flocks have been cleaned up. In addition, Nigeria and surrounding countries need serious public-education campaigns about the danger of contact with dead birds. When outbreaks occur, governments should immediately offer realistic compensation to farmers for birds lost to disease and culling. Without this, poor farmers will be tempted to hide bird-flu outbreaks and continue to sell poultry that should be culled. Farming practices that mix poultry species in farms or live animal markets are a danger too, and must be addressed—although that might take longer. The effort would be helped if those in the poultry industry and governments in poultry-exporting nations would stop simply pointing to the risks posed by wild birds and start paying more attention to the movement of animals, products and people from infected to uninfected regions and countries. Unusually for a complex problem with international ramifications, money is available to make a serious attempt at tackling it—$1.9 billion was pledged by the world's wealthier nations. There is no excuse for delay, unless we want more dead people to follow lots more dead ducks.

单选题 Countless medical studies have concluded that playing too many video games can be harmful to one's health. Now, however, it turns out that one of the more popular video-game consoles on the market, the Xbox 360, could be used to save lives. A computer scientist at the University of Warwick in England has devised a way to use an Xbox 360 to detect heart defects and help prevent heart attacks. The new tool has the potential to revolutionize the medical industry because it is both faster and cheaper than the computer systems that are currently used by scientists to perform complex heart research. The system, detailed in a study in the August edition of the Journal of Computational Biology and Chemistry, is based on a video-game demo created by Simon Scarle two years ago when he was a software engineer at Microsoft's Rare studio, the division of the U.S.-based company that designs games for the Xbox 360. Scarle modified a chip in the console so that instead of producing graphics for the game, it now delivers data tracking how electrical signals in the heart move around damaged cardiac cells. This creates a model of the heart that allows doctors to identify heart defects or conditions such as arrhythmia, a disturbance in the normal rhythm of the heart that causes it to pump less effectively. "This is a clever use of a processing chip ... to speed up calculations of heart rhythm. What used to take hours can be calculated in seconds, without having to employ an extremely expensive, high-performance computer," Denis Noble, director of Computational Physiology at Oxford University, tells TIME. To create a heart model now, researchers must use supercomputers or a network of PCs to crunch millions of mathematical equations relating to the proteins, cells and tissues of the heart, a time-consuming and costly process. Scarle's Xbox system can deliver the same results at a rate five times faster and 10 times more cheap, according to the study. "These game consoles aren't just glorified toys. [They] are pieces of very powerful computing hardware," Scarle says. "I can see this ... being most useful for student sand early-career scientists to just quickly and cheaply grab that extra bit of computing power they otherwise wouldn't be able to get."Scarle attributes his breakthrough creation to his unusual background of working as a software engineer in the gaming industry and performing electrocardio-dynamics research at the University of Sheffield in England. The idea for the heart-modeling tool came from a "little shooter game" he developed at Microsoft in which a player tries to gun down enemies in an arena meant to resemble a heart. "I did a game-ified version of my old cardiac code. I could actually present some 'proper' science [based on] the cool things us game developers do," Scarle says. The Xbox 360 isn't the only video-game console that is being used for scientific research. At the University of Massachusetts campus in Dartmouth, scientists are using Sony PlayStations to simulate black-hole collisions to try to solve the mystery of what happens when a super massive black hole swallows a star. So perhaps parents shouldn't be too worried if their children are spending an inordinate amount of time playing video games. Who knows, today's Grand Theft Auto or Halo addict may end up discovering a new moon around Saturn or finding a cure for cancer.
