New U.S. Plan for Disease Prevention
Urging Americans to take responsibility for their health¹, Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease, cancer and diabetes.
The initiative highlights the cost of chronic diseases²--- the leading causes of death in the United States --- and outlines ways that people can prevent them, including better diet and increased exercise.
“In the Unites States today, 7 of 10 deaths and the vast majority of serious illness, disability and health care costs are cause by chronic diseases,” the Health and Human Services Department said in a statement.
The causes are often behavioral --- smoking, poor eating habits and a lack of exercise.
“I am convinced that preventing disease by promoting better health is a smart policy choice for our future,” Thompson told a conference held to launch the initiative.
“Our current health care system is not structured to deal with the escalating costs of treating diseases that are largely preventable through changes in our lifestyle choices.”
Thompson said heart disease and strokes will cost the country more than $351 billion in 2003.
“These leading causes of death for men and women are largely preventable, yet we as a nation are not taking the steps necessary for us to lead healthier, longer lives,” he said.
The $15 million is slated to go to communities to promote prevention, pushing for changes as simple as building sidewalks to encourage people to walk more.
Daily exercise such as walking can prevent and even reverse heart disease and diabetes, and prevent cancer and strokes.
The money will also go to community organizations, clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening.
The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests³ for cervical cancer, mammograms for breast cancer, colonoscopies, and prostate checks.
If such cancers were all caught by early screening, the group estimates that the survival rate for cancer would rise to 95 percent.

Eat to Live
A meager diet may give you health and long life, but it’s not much fun --- and it might not even be necessary. We may be able to hang on to¹ most of that youthful vigor even if we don’t start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse’s liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won’t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.²
Spindler’s team fed three mice a normal diet for their whole lives, and fed another three on half-rations.³ Three more mice were switched from the normal diet to half-feed³ for a month when they were 34 months old --- equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production4--- probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 per cent of these gene changes.
“This is the first indication that these effects kick in5 pretty quickly,” says Huber Warner from the National Institute on Aging near Washington, D.C..
No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. “There’s attracting and tempting evidence out there that it will work,” he says.
If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to made sure a drug is effective.
But Spindler isn’t sure the trade-off is worth it6. “The mice get less disease, they live longer, but they’re hungry,” he says. “Even seeing what a diet does, it’s still hard to go to a restaurant and say: ‘I can only eat half of that’.”
Spindler hopes we soon won’t need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.
词汇：
meager adj. 不足的 youthful adj. 有青春活力的
vigor n. 精力，活力 metabolize vt. 使（一种物质）进入新陈代谢过程
rejuvenation n. 恢复活力，返老还童 liver n. 肝脏
toxin n. 毒素 ration n. 定量
inflammation n. 炎症，发炎 trade-off n. 交换，交易
rejuvenate vt. 使恢复活力，使回春
注释：
1. hang on to : 继续保留。例如：You should hang on to that painting --- it might be worth a lot of money one day. (你应该继续保留那幅画，或许有一天它会值很多钱。)
2. The genetic rejuvenation won’t reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. 老鼠的肝部基因恢复活力不会逆转老鼠在其他方面的老化，但却有助于肝脏代谢药物或出去毒素。Other damage caused by time 岁月造成的其他方面的破坏，即“其他方面的老化”。Metabolize drugs: 代谢药物，即“使药物参与新陈代谢以提高药效”。Get rid of : 摆脱，除去。
3. half-ration 和half-feed: 都是指“老鼠饲料正常定量（normal diet）的一半”。
4. free radical production : 指“（有机体组织、器官等的）无限激增”。
5. kick in: 意为“开始起作用”。如：We’re still waiting for the air conditioning to kick in. （我们还在等着空调开始起作用。）
6. be worth it: 意为“值得，有益”。例如：They are expensive, but they are worth it. (那些东西很贵，但划得来。)

Can Buildings Be Designed to Resist Terrorist Attack?
In the aftermath of¹ the terrorist attack on the World Trade Center, structural engineers are trying hard to solve a question that a month ago would have been completely unthinkable: Can building be designed to withstand catastrophic blasts inflicted by terrorists?
Ten days after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) headquartered at UB traveled to ground zero² as part of a project funded by the National Science Foundation. Visiting the site as part of MCEER reconnaissance visit, they spent two days beginning the task of formulating ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged, but still are standing³.
“Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage4,” said M. Bruneau, Ph.D. “Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies5 to achieve enhanced performance of buildings6 in the event of terrorist attacks,” he added.
Photographs taken by the investigators demonstrate in startling detail7 the monumental damage inflicted on the World Trade Center towers and buildings in the vicinity. One building a block away from the towers remains standing, but was badly damaged. “This building is many meters away from the World Trade Center and yet we see a column there that used to be part of that building,” explained A. Whittaker, Ph.D. “The column became a missile that shot across the road, through the window and through the floor.”
The visit to the area also revealed some surprises, according to the engineers. For example, the floor framing8 system in one of the adjacent buildings was quite rugged, allowing floors that were pieced by tons of falling debris to remain intact9. “Highly redundant ductile framing systems may provide a simple, but robust strategy for blast resistance,” he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. “We also need a better understanding of the mechanism of collapse,” said A. Whittaker. “We need to find out what causes a building to collapse and how you can predict it.”
A. Reinhorn, Ph.D. noted that “earthquake shaking has led to the collapse of many buildings in the past. It induces dynamic response and extremely high stresses and deformations in structural components. Solutions developed for earthquake-resistant design may be directly applicable to blast engineering and terrorist-resistant design. Part of our mission now at UB is to transfer these solutions and to develop new ones where none exist at present.”

aftermath n. 后果，结果 in the vicinity 附近
withstand v. 经受住 debris n. 碎片
inflict v. 使遭受，施加 intact adj. 未受损伤的，完整无缺的
