That“s comforting. Bu

7、t it“s also misleading because there“s actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4.5 billion years ago.

8、They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust (地壳), eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They“ve found new evidence suggesting

9、that Earth“s crust started shifting at least 3.8 billion years ago. The new estimate is 1.3 billion years earlier than previous ones. Not long before 3.8 billion years ago, lots of asteroids (小行星) were hitting Earth, keeping its crust in a hot, melted state. After the hard crust formed, much of it s

10、ank at various times into the planet“s hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地壳) belt. The rocky crust there is between 3.7 and 3.8 billion

11、 years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists

12、propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock, called magma (岩浆), flowed up slowly from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests th

16、 have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack. The test measures levels of a protein in the blood. The researchers say people with high levels of this protein are at high risk of heart attack, heart failure or stroke. Kirsten Bibbins-Do

17、mingo of the University of California in San Francisco led the team. For about four years, they studied almost one thousand patients with heart disease. The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more lik

18、ely than those with the lowest levels to have a heart attack, heart failure or stroke. The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way. The study involved mostly men, so the researchers could not say for sure that

19、the results are also true for women. They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure. Other researchers say more studies are needed to confirm if knowing the protein levels of a heart patient should affect that person“

20、s treatment. They also would like to know if more aggressive treatment could reduce the patient“s chance of a heart attack or stroke. The study appeared in the Journal of the American Medical Association . Could a little sleep during the middle of the day reduce the risk of a heart attack? An unrela

21、ted study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes. In countries like the United States, afternoon naps are mostly for children. But they are common for adults in Mediterranean countries. And these countries generally have lower rates of heart disea

22、se. So scientists in the United States and Greece wondered if naps could play a part. Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens. Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death fr

23、om heart problems than people who did not take naps. The researchers say napping may improve heart health by reducing stress. They say the research suggests that naps are especially good for working men. But they say not enough female subjects died during the study to judge the benefits for women.（分

Usually it does not last lo

28、ng, but it may feel like forever. The cause can be something as normally uneventful as driving over a bridge or flying in an airplane. And it can happen even if the person has driven over many bridges or flown many times before. A fast heart beat. Sweaty hands. Difficulty breathing. A lightheaded fe

29、eling. At first a person may have no idea what is wrong. But these can all be signs of what is known as panic disorder. The first appearance usually is between the ages of 18 and 25. In some cases it develops after a tragedy, like the death of a loved one, or some other difficult situation. In the U

30、nited States, the National Institute of Mental Health (NIMH) says more than two million people are affected in any one-year period. The American Psychological Association says panic disorder is two times more likely in women than men. And it can last anywhere from a few months to a lifetime. Panic a

31、ttacks can be dangerousfor example, if a person is driving at the time. The Chesapeake Bay Bridge in the state of Maryland is so long and so high over the water, it is famous for scaring motorists. There is even a driver assistance program to help people get across. Some people who suffer a panic at

32、tack develop a phobia, a deep fear of ever repeating the activity that brought on the attack. But experts say panic disorder can be treated. Doctors might suggest anti-anxiety or antidepressant medicines. Talking to a counselor could help a person learn to deal with or avoid a panic attack. There ar

33、e breathing methods, for example, that might help a person calm down. Panic disorder is included among what mental health professionals call anxiety disorders. A study published last week reported a link between anxiety disorders and several physical diseases. It says these include thyroid disease,

34、lung and stomach problems, arthritis, migraine headaches and allergic conditions. Researchers at the University of Manitoba in Canada say that in most cases the physical condition followed the anxiety disorder. But, they say, exactly how the two are connected remains unknown. The report in the Archi

39、ded amount of salt, raising their risk for high blood pressure, heart attacks and strokes, government health experts said on Thursday. They found nearly 70 percent of U.S. adults are in high-risk groups that would benefit from a lower-salt of no more than 1,500mg per day, yet most consume closer to

40、3,500mg per day. “It“s important to eat less salt. People who adopt a heart healthy eating pattern that includes a diet low in sodium and rich in potassium and calcium can improve their blood pressure,“ Dr. Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement. “Peopl

41、e need to know their recommended daily sodium limit and take action to reduce sodium intake,“ Labarthe said. The study in CDC“s report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are blac

42、k or over the age of 40which are considered high-risk groups. Yet studies show most people in the United States eat 3,436 mg of sodium per day, according to a 2005-2006 CDC estimate. Most of the sodium eaten comes from package, processed and restaurant foods. The CDC said it will join other agencies

43、 in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply. Nationwide, 16 million men and women have heart disease and 5.8 million are estimated to have had a stroke. Cutting salt consumption can reduce thes

47、reducing risk factors related to certain diseases. The conclusion is the result of the study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables. Juices are compara

48、ble in their ability to reduce risk compared to their whole fruit/vegetable counterparts, according to several researchers in the United Kingdom who conducted the literature review. The researchers analyzed a variety of studies that looked at risk reduction attributed to the effects of both fiber an

49、d antioxidants. As a result, they determined that the positive impact fruits and vegetables offer come not just from the fiber but also from antioxidants which are present in both juice and the whole fruits and vegetables. “When considering cancer and coronary heart diseases prevention, there is no evidence that pure fruit and vegetable juices are less beneficial than whole fruit and vegetables,“ the researchers said. The researchers added that the positioning of juices as being nutritionally inferior to whole fruits and vegetables in relationship to chroni
