mmlu_train_85168 | You've got plenty of emails from your mom, and maybe even a few from dear old grandma. But have you ever received a message from a river? Now, Ireland's River Lee is sending out much information, thanks to wireless technology. In a program called the DEPLOY project, scientists have put some sensors in rivers that can find pollution levels. Instead of asking scientists to collect water _ several times a day, the government can now examine pollution levels in the water, and find out if there is anything polluted entering the river. This makes it much easier for scientists to protect the environment, since problems can be discovered before a serious pollution accident really happens. People in the area can also receive free reports from the river, so that they can find out whether the water is safe for swimming or boating on a certain day. And people can also know if the water is clear enough for them to drink and use. The DEPLOY project has not only started in Ireland, also the same programs have started in thousands of places around the U.S. Now you live in a world in which you could receive information with your mobile phone about environment. The technology should help to make us know more about the pollution that surrounds us--which just might get us all a little more involved with trying to clean up our world.

mmlu_train_65378 | The immune system is the body's defender. It identifies, tracks down, and destroys troublemakers before they can hurt the body. Those troublemakers may be, for example, bacteria from a cut or splinter, a measles germ, a cold bug, or even a cancer cell. These invaders try to take over our tissues and feed off our bodies' nutrients. If they succeed, we become sick or, sometimes, even die. It's the job of our immune systems to destroy these invaders before they destroy us. Say you picked up a flu virus last week. Perhaps it entered your body through a cut, from a drinking glass, or from the air you breathe. Of course, you didn't feel it, but the virus made its way into your bloodstream. As soon as it entered your body, it began to reproduce. Viruses have only one goal: to take over your cells. Once inside your body, viruses try to enter cells and disrupt their normal work. If left alone, these viruses would hurt so many cells that you would weaken, or worse, get a serious illness. But this flu virus should not be so complacent as it seems to be. As it reproduces in your bloodstream, the virus is met by a certain kind of white blood cell, the lymphocytes. The _ are the foot soldiers that keep you alive. The number of lymphocytes in your body is hard to imagine. Thousands of them could fit in the period at the end of this sentence. Your body holds about a trillion --that's 1,000,000,000,000 of them, or about 3,000 in every drop of blood. _ Some of these lymphocytes pass through a small walnut-sized organ called the thymus. The thymus is the base of the neck. Here, special hormones turn lymphocytes into fighting cells, called T cells. T cells have one terrific talent: They can tell the difference between friend and foe; what should be in our bodies and what shouldn't. They do not affect the body 's healthy cells. Yet they attack everything that is foreign to our bodies, such as germs, transplants, and even our own cells which have become abnormal, as in the case of cancer. Which of the following questions best summaries the main idea of the whole passage? | [

mmlu_train_86467 | "An apple a day keeps the doctor away." Well, milk may work in the same way! Milk is the natural food for mammalian babies. It helps them grow strong because it is rich in protein , calcium and vitamins. Milk can also help you sleep better because it calms you down. But remember to drink milk with care. Find out how old the milk is. Make sure it is fresh and hasn't gone bad. Don't drink milk when your stomach is empty. Eat some bread or corn at the same time. That'll help you take in more protein and vitamins. Doctors say teens need at least 500ml of milk a day. That's two or three cups. Milk-drinking started long ago, as early as 6,000-8,000BC. At that time people started to keep cows, sheep and goats to get their milk. Of course what you drink today isn't that fresh from the cow. People cool the fresh milk down to 40C to stop the bacteria growing. In factories, milk is pasteurized to stop it growing bad. After disinfections and packaging, it goes to the supermarkets. Yoghourt also comes from milk. People make some special bacteria to change the taste of milk and make the nutrients in it easier for people to take in. Maybe that's why it's getting more popular with people! The sentence "An apple a day keeps the doctor away." tells us that _ . | [

mmlu_train_60984 | In the next five years, STEM (science, technology, engineering and mathematics) jobs are projected to grow twice as quickly as jobs in all other fields according to the U.S. Bureau of Statistics. While all jobs are expected to grow by 10.4 percent, STEM jobs are expected to increase by 21.4 percent. By this measure, future STEM jobs represent a huge opportunity to today's students. But, in fact, of the 3.8 million ninth graders in the U.S., only 233,000 end up choosing a STEM degree in college, according to the National Center for Education Statistics. This means only 6 percent of ninth graders will become STEM graduates. And of these graduates, women will be even more underrepresented in most STEM fields. These are alarming statistics. How do we get more young boys and girls to be interested in STEM-related fields? It isn't an easy task. Schools do not always adequately prepare students for these severe subjects, and college programs are designed to get rid of those who are less persistent. Nationally, only 41 percent of initial STEM majors who begin a degree in STEM-related fields complete their degree in less than six years. In addition, social pressures continue to cast a shadow over girls who might otherwise consider the STEM fields. A couple of years ago, I met amazing parents, both of whom had a background in engineering and hoped their 10-year-old daughter would follow in their footsteps. They encouraged her to take an after-school science / robotics program. When she got there, she found she was outnumbered 6:1 by boys in the class. As the only girl, she came home crying much of the time because she was teased and told that geeky girls are not welcome in the boys' club. Ironically, by the time young boys are entering college programs in STEM fields, many complain about the lack of girls. Starting at an early age, even as young as kindergarten, we need to encourage and help the next generation leaders to consider taking up science, computing, math and technology. We also need to realize that for young girls to be inspired to take and stick with this educational path and later career field, they will benefit from the support of the people that surround them: parents, teachers, friends and family members.

mmlu_train_58209 | Some weight-loss camps, which are rare in China just a few years ago, have sprouted in Beijing, Qingdao, Shenzhen, and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight. Of these, 90 million--about 7 percent--are obese . Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The trend, they say, will have a huge impact on the health of China's citizens and economy. "We're seeing a very large proportion of children and adolescents who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing health-and-nutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly". In just ten years China's childhood obesity rate has doubled, with the greatest gains coming in urban areas. "In big cities it's a big problem." Some experts blame the extra fat on a range of factors, many of them tied to China's rapidly changing economy and culture. The diets of Chinese adults and children are far higher in calorie-laden meats, fish, eggs, dairy products, fats, and sugars than ever before. In addition, kids--especially city dwellers--are more sedentary today and spend more time indoors in front of homework, television, computer games, and the Internet. Shuwen Ng, a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features. China's childhood obesity rate still lags that of the United States, where some 15 percent of kids are said to be obese. But the long-term effects are equally serious. According to the passage we can infer _ . | [

mmlu_train_9479 | Jayson McCarthy, 12, was born without fingers on his left hand. That didn't stop him from being able to do many tasks. But Jayson could not grasp more than one object at a time. So Jayson 's father, Paul, created a Prosthesis , using a 3D printer. Now Jayson has fingers that open and close. "It was a do-it-yourself, father-and-son adventure," says Paul. When Jayson was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. "The doctor said Jayson should first learn to get full use out of the hand he was born with," says Paul. As Jayson got older, his father looked into _ a prosthetic hand, which can cost as much as $30,000. Paul found a more affordable solution. One day, Paul discovered a video on the Internet about Robohand, a prosthesis created with a 3D printer. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3D printer--which costs around $2,000--and some materials. Luckily, Jayson 's school had recently purchased a 3D printer and it offered to help Paul build the hand for Jayson n. "We used a soccer shinguard , cardboard , and tape. They cost about $10," says paul. With his new hand, Jayson can do things better. "I can help my mom more, because now I can carry two grocery bags," he says. Jayson 's father has already built several hands for Jayson. Jayson helps design each one. He says there's one thing in particular that he wants to do with a future prosthesis.

mmlu_train_54996 | But what is teacher quality? How can one measure it reliably? An analysis is issued on a sample of data from a Texas school district. Experts argue convincingly that teacher effectiveness should be measured by students' gains on standardized tests: Mr. Smith is probably a better teacher than Ms. Brown if his students consistently improve their test scores more than hers do. Though this approach is appealing, there are tricky issues. For example, what if Ms. Brown teaches in a school where students score so high there is little room for improvement? The authors try to correct for this problem, as well as other sorts of measurement issues, to generate a measurement of teacher effectiveness. The paper is primarily concerned with how this measure is related to other observable characteristics. The first finding is that there is a large variation in teacher effectiveness: some teachers consistently have a larger impact on their students' achievement than others. Second, easily observable characteristics like having a master's degree or a passing score on the teacher certification exam are not correlated with teacher effectiveness. Then what does matter? The most important single influence is experience: first-year teachers are much less effective than others. The second year is significantly better, and by the fourth year, _ . It is not entirely clear whether this experience effect is learning by doing (the more you teach, the more effective you become) or survival of the fittest (those who are not good at teaching tend to drop out early.) From my reading of the paper, both effects appear important and there is no simple answer. The data do suggest, however, that teacher effectiveness is pretty clear by the end of the second year, so the information to make an informed decision is available at that time. The authors also investigate the contentious issue of racial matching of students and teachers. Here they find strong evidence that minority teachers tend to be more effective with minority students. Again, it is unclear whether this is because of a role model effect (students respond better to a teacher of their own race) or an empathy effect (teachers empathize better with students of their own race) or something else entirely. The authors also look at teacher mobility. There is some evidence that teachers who quit teaching or switch schools tend to be below average in effectiveness. This is consistent with the survival-of-the-fittest model. The schoolmaster could decide wisely whether to further employ the teacher by the end of the _ . | [

mmlu_train_39196 | Offering a powerful new tool against terrorism, researchers have found a way to detect lies in the liar's blushing face. The technique, described in the journal Nature, uses a thermal camera to detect the sudden shift of blood flow in the face. The system performed as a traditional polygraph , the scientists report. Pushed by technological advances and with fresh interest since Sept.11, the discovery is part of the development in the scientific study of detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new methods that might take the place of the polygraph, from brain scans, to slight changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding says, when a person tells a lie, there is a sudden change of blood to the area around the eyes. Although the change is not ordinary visible, the blood warms the skin, causing bands of color1 to appear through a camera sensitive to heat. One advantage of the camera can provide answers quickly, and doesn't require a highly trained expert to operate it or explain its results. In theory, this new technology could be used anywhere large numbers of people need to be quickly screened. But some scientists say the technology would need to be improved before it is ready for use, for it is possible that there are other reactions that cause a sudden change in blood flow in the face and there is also the danger that people will learn to fool the machine, the same way they try to fool polygraph examiners by controlling their breathing or taking drugs to relax themselves. We can infer that _ inspires the finding of the new way of detection. | [

mmlu_train_20018 | Sitting too much is now listed with smoking and junk food as a bad habit that increases your risk of heart disease. New Australian research shows that half-an-hour in the gym will not make up for the waist-expanding damage caused by spending the rest of the day sitting. But the good news is that doing chores in the house or gently walking around the office while on the phone might be enough to keep you fit. The study joins the growing body of evidence suggesting too much sitting might undo the benefits of exercise. The study measured the intensity of physical activities in 168 subjects over seven days. It found that, regardless of how much exercise they did or their total sitting time, those who took more breaks from sitting had lower risk of thick waists and lower levels of blood lipids . "Higher levels of blood lipids have been linked to a heightened risk of heart disease," principal researcher Genevieve Healy of the University of Queensland said. "What the study shows is that there are benefits in just getting up regularly and interrupting your sitting time." Researchers behind the Stand Up Australia project have written to the Rudd Government requesting $3.5 million for a two-year study into the impact how long sitting offects health and productivity of workers. The study would also develop and test strategies for reducing sitting time on the job. The latest study builds on work that is shifting the health promotion focus from purposeful exercise, such as running, to lower intensity activities throughout the day. The Australian research has been backed up by US studies. "To hold a body that weighs 77 kilograms upright takes a fair amount of energy from muscles," said Professor Marc Hamilton from the University of Missouri. "There is a large amount of energy associated with standing every day that cannot easily be replaced by 30 to 60 minutes in the gym." The new Australian research shows that _ . | [

In the last several years,Bill Gates has slowly given control of Microsoft to others.In two thousand,he gave the job of chief executive officer to Steve Ballmer, a friend of his since their years at Harvard University.Mister Ballmer has been with Microsoft since nineteen eighty.Still,it is hard to overestimate the influence of Bill Gates on computing.He developed the business model that put the Windows operating system on about ninety percent of the world's one billion PCs.Microsoft now has almost ninety thousand employees. At fifty--two years old,Bill Gates is currently the third richest man in the world.He is worth about fifty-eight billion dollars.He remains Microsoft's biggest shareholder. Mister Gates will now spend most of his time working at his charity organization, the Bill and Melinda Gates Foundation.The foundation is the world's largest charity with over thirty-seven billion dollars.It provides money for health, education and other projects,mostly in developing countries.

It is important to know the ways you can use and show them to everyone else in the family, such as stairways and emergency exits, but not elevators. From the lower floors of building, escape through windows is possible. Learn the best way to get out from a window with the least chance of serious injury. The second floor window is usually not very high from the ground. An average person, hanging by the fingertips will have a drop of about 6 feet to the ground. It is about twice the height of an average man. Of course, it is safer to jump a short way down than to stay in a burning building. Windows are also useful when you are waiting for help. Be sure to keep the door closed before opening the window. Otherwise, smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked into the room. On the second or third floor, the best windows for escape are those which open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement might end in injury.

These are the preliminary findings of PHD research by Anne Bartlett-Bragg, a lecturer at the University of Technology, Sydney, who has been using weblogs or blogs in her own teaching since 2001. "The students are thinking more critically." she says, "They are learning to be responsible and they're communicating outside the boundaries of the classroom and the institution, and they like that. "Bartlett-Bragg says in conventional teaching, students often rely on the lecturer as the main source of ideas and critique for their work. "I'm a bit over listening to my students giving me back in an essay what I've told them in class." she says. "I want them to think for themselves and get different perspectives." "What makes blogs useful is their interactive nature." she says. These web-based forums for discussing ideas, experiences or opinions allow students to discuss publicly what they are studying with other students and experts outside their own university. "I really encourage them to put their personal opinion in there, provided they are informed and backed up with evidence." Bartlett-Bragg says because a lot of academics in her field of electronic or e-learning now have their own blogs, students can engage directly with them. She says one of the most powerful facilities in weblogs is pinging, which involves a person positing a comment about someone else's work on their own blog. They use the "Trackback" tool to notify the author when they have published the comment, basically inviting them to discuss it. "They get such a buzz when they make a comment on another person outside the boundaries of the institution and that person responds, or even gives them some further reading." she says.

Not having treats can be good for your health. I've heard that the Burts, a family of five in South East England, lived sugar free for a whole year after they found out their daughter had diabetes . It wasn't easy. To avoid temptation, I don't go to any bakeries, but this family actually owns one, which makes up to 3,000 cakes a week. And how does it feel to live without sugar for a while? Jason Burt said that for a month they felt weak. But later on it all changed. He says he feels "more awake" and full of energy. And what about the Burt family business?

A dentist may be able to put the tooth back in for you, but you have to get to the dentist first.In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is put the tooth back into your mouth, or you could put it in milk.Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth.He tried putting teeth into milk, into water, and into cell-culture medium .He also tried, just drying the teeth in the open air.He used teeth that had to be removed from people's mouths for various reasons.The teeth were put into one of the solutions or stored in the air for one hour.Then cells from the root of the teeth were scraped-off the teeth.Dr.Courts and the others then studied how healthy these cells were. The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth.However, few people keep cell-culture medium handy at home or in school. The next best thing was milk.But Dr.Courts said that the best thing of all was to wash the tooth and put it right back into its socket in the mouth.For some people, though, this is just too painful or upsetting.So milk will do, until you get your tooth (and your mouth)to a dentist.

mmlu_train_53928 | US researchers have found traces of an ancient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life. The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the University of Colorado. "This is the first clear evidence of shorelines on the surface of Mars," said Boulder's research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters. "The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago."[:] Analysis of the images has shown the water carved out the canyon in which it was found, which then opened out into a valley depositing sediment which formed a delta . "Finding shorelines is a great discovery to us," said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry. Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago. The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study. Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life.

mmlu_train_65310 | Elephants have impressed us for centuries. They are big, clever, and sociable. But what if someone told you that they may also hold the key to fighting cancer? People have been wondering why elephants do not develop cancer, even though they have life spans that are similar to humans, living for around 50 to 70 years. Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors from developing. To be precise, they found 20 copies of an anti-tumor gene called TP 53 in elephants. Most other species, humans included, only carry one copy. According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animal's sensitivity to DNA damage. This lets the cells quickly kill themselves when damaged before they can form deadly tumors. "An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals," study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass. _ was found by Oxford University scientist Richard Peto in the 1970s and later named "Peto's paradox". Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephant's case, the making of TP53 is nature's way of keeping this species alive. The study also found that when the same genes were brought to life in mice, they had the same cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place. "Nature has already figured out how to prevent cancer," said Joshua Schiffman, an oncologist at the School of Medicine, University of Utah, US. "It's up to us to learn how different animals tackle the problem so we can use those strategies to prevent cancer in people." Why are elephants unlikely to develop cancer? | [

But Alzheimer's disease is not confined to the aged. There may be a million or more people under the age of 65 suffering from the disease. At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic disease that destroys brain cells. Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, then the patient's memory begins to fail. He may forget dates, numbers, names and plans. As the disease progresses, the patient may not recognize family and friends. These symptoms often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior. In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk. Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus .It may be caused by a poisonous substance in the environment. At present, there is no cure for the disease. But there are ways to slow its progress.

Many sleep experts hope it will be _ According to a poll by the National Sleep Foundation, nearly 4 in 5 Americans don't get as much sleep as they should during the workweek. On average, adults are thought to need at least eight hours of sleep a night, although some can manage with less and some won't do well without more. But the survey found that, on workdays, only 21% of Americans actually get a full eight hours of sleep, and another 21% get less than six. To many of us, the thought of spending more time sleeping is, well, a big yawn. On the other hand, the thought of being smarter, thinner, healthier and more cheerful has a certain appeal. And those are just a few of the advantages that can be ours if we consistently get enough sleep, researchers say. Also on the plus side: We're likely to have better skin, better memories, better judgment, and, oh, yes, longer lives. "When you lose even one hour of sleep for any reason, it influences your performance the next day," says Dr. Alon Avidan, director of the UCLA Sleep Disorders Center. A study published last year found the same to be true even of children. When kids aged 8 to 12 slept for just one hour less for four nights, they didn't function as well during the day. But sleeping has an image problem. "We see napping or sleeping as lazy," says Jennifer Vriend, a clinical psychologist in Ottawa, Canada, and the leading author of the study with children. "We put so much emphasis on diet, nutrition and exercise. Sleep is in the back seat."

The Lasker Awards have existed since 1945. The winners are always people who have really helped us to understand, recognize, treat, cure and prevent disease. Tu was presented the 2011 Lasker Clinical Medical Research Award on September 23. She discovered a drug called artemisinin . The drug is now widely used against malaria . Tu and her colleagues joined a government project to find a new malaria drug in the late 1960s during the "cultural revolution" (1966~1976). They made 380 herbal extracts from 200 potential recipes. The recipes came from traditional Chinese medical books. The team then tested them on malaria-infected mice. Finally Tu became interested in an extract of the plant qinghao, or sweet wormwood . According to an ancient Chinese medicine book, qinghao was once used to treat malaria. However, the extract they made in the lab didn't work well. Tu thought the effective ingredient in qinghao may be destroyed by high temperatures. Therefore, Tu tried to make the extract with ether which has a much lower boiling point than water. In 1971, after more than 190 failures, Tu finally got an extract that was 100 percent effective against the malaria parasites . The extract was called qinghaosu, later renamed artemisinin. According to a statement on the Lasker Foundation website, during the past four decades, Tu's drug has saved millions of lives. It is especially important for children in the poorest and least developed parts of the world. However, not many people knew of the scientist until she won the Lasker Award this month. Lasker Awards are known as "America's Nobels" for the reason that in the last two decades, 28 Lasker Prize winners have gone on to receive the Nobel Prize, and 80 since 1945, according to Xinhua News Agency. "The discovery of artemisinin is a gift to mankind from traditional Chinese medicine, " Tu said when she received the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world. " In the process of discovering artemisinin, Tu _ . | [

mmlu_train_17157 | The current Ebola outbreak in western and central Africa has infected at least 3,069 people, including 1,552 dead, making it the largest outbreak in history. Ebola is a deadly virus --about 60 percent of people infected with it have died. How is Ebola doing its harm? When a person becomes infected with Ebola, the virus damages the body's immune cells, which defend against infection, said a researcher at Lancaster University. But if a person's immune system can stand up to this attack, then he is more likely to survive the disease. The patients that survive it best are those who don't get such a bad disadvantage in immune system. But if the body isn't able to get rid of this attack, then the immune system becomes less able to regulate itself. This means the immune system is more likely to run out of control, leading to a drop in blood pressure, multi-organ failure and eventually death. What are the common symptoms of the disease? Fever. Headache. Joint and muscle aches. Weakness. Diarrhea. Vomiting. Stomach pain. Lack of appetite. Chills. Rash. Redness in the eyes. Hiccups. Cough. Sore throat. Chest pain. Difficult breathing or swallowing. Bleeding inside and outside of the body. How to prevent the spread of Ebola? Ebola can be spread primarily via direct contact with patients, specifically the blood and fluids of an infected patient. We should avoid contact with infected patients and objects such as clothing, bedding, and needles used by them. Avoid areas where infections have been reported. For now, the disease has only been confirmed in central and West Africa, four cases in America and Europe. Avoid eating wild-caught bush meat. Researchers have suspected that the disease came to humans via animals, probably through the meat of primates . If you're in an area where the disease has been reported, avoid purchasing, eating, or handling wild game to stay on the safe side. Wear protective medical clothing if you're around infected patients. Extreme caution is necessary. Hospital workers must use masks, gloves, goggles, and gowns, which needed to be worn at all times if you're around infected patients. How Do People Survive Ebola? Doctors don't know for certain who will survive Ebola, and there is no specific treatment or cure for the disease. Although in the minority, some people do recover from infection. Our suggestions include: Maintain your electrolytes and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygen-rich environment. Quickly address any symptoms of infection. Be honest about when and where you're feeling pain.

mmlu_train_34774 | In American crime movies, policemen search crime scenes for anything that might belong to a criminal-- bits of fingernail , blood or hair-- in order to find out who they are. What they hope to find is the key to their identity--their DNA. DNA is the chemical that contains a person's genetic makeup. Every person, except for identical twins, has unique DNA information. That is why we can use it to identify someone. There is no doubt that DNA evidence is becoming a very powerful tool for law enforcement officers. In the US, all 50 states and the federal government keep DNA databases of some criminals after they have been convicted . Whenever a crime happens, the police collect DNA from the crime scene and compare this with samples they already have in the criminal database. If they match any suspect in the database, then they've caught their criminal. Even if they don't, the DNA sample can still be used to determine the person's sex, height, hair and eye color1 and other characteristics. This helps police to create a physical profile of the criminal. Some people feel that the database should be made bigger to contain everyone's DNA and help to solve many more crimes. This would also avoid mistakes when someone is wrongly convicted of a crime. DNA doesn't make mistakes. However, other people are worried that it would violate their privacy. Someone's DNA can be used to gather information such as the person's family and ethnic background, whether he or she has a gene mutation or certain genetic diseases, and other personal issues. People are afraid that this information might be used inappropriately. They may fear that employers might read it and treat them differently. People may also be afraid that personal data might get into the hands of insurance firms or loan companies. For example, if they knew from your DNA that you had a genetic risk of a serious disease, they might be able to refuse you life insurance, a loan, or even a job. Clearly, the use of DNA evidence will continue to help the police solve crimes. However, social and ethical concerns about DNA will also remain a topic of debate.

mmlu_train_65823 | A tropical rain forest is an amazing place. Thousands of different kinds of plants and animals make their homes there. Some are not found anywhere else in the world. If the rain forests are not protected, some species of plants and animals could disappear forever, taking their resources with them. Scientists have known for a long time that medical cures can come from plants. The rain forest is the perfect habitat for various types of plants. They compete for space, sunlight, water, and nutrients. The plants that survive are strong. They also contain many types of chemicals. These chemicals are part of the plants' defence system. They can help protect the plants from bacteria, insects, diseases, and other threats. Experts believe that some of these chemicals might be useful to human beings, too. The native people of the rain forests have healers who help those who are sick. For hundreds of years, they have known which leaves, roots, and berries can be used to treat different illnesses. Western scientists have begun working with these native healers. They learn about different plants, cures, and treatments. Then, they can perform tests on the plants to see what chemicals they contain and how they might be used. When they do find something important, it goes through more and more tests. Lots of experiments must be done over a long period of time before something can be safely sold as a drug. Scientists want to be sure that it works and that the risk of using it isn't too high. American scientists have set up labs in the countries where the rain forests are. They do studies and research there. They also employ scientists and workers who live in these countries to help them. This allows the local people to benefit from research on the rain forests. They can make money from the rain forest without destroying it, which is very important. If the rain forest is valuable to them, they will help protect it. The more people who are trying to protect the rain forests, the better. Just imagine the cures that might be found there!

mmlu_train_23241 | So you think you know your dog. But how well does your dog know you? She probably recognizes you when she sees you. But can a dog tell by simply looking at you whether you have a happy or an angry expression on your face? Researchers in Austria have taught pet dogs to know the difference. Dogs are very mindful of sound. When dog owners shout or speak in a strong, unkind voice, dogs often act ashamed and quietly move away from the area. Recently, researchers found that dogs can look at our faces, and tell the difference between a smile and a frown . The animals were able to recognize a look of praise from one of blame. Researchers at the University of Veterinary Medicine, Vienna performed a series of experiments. They taught dogs to recognize facial expressions. They showed the dogs two pictures of either the upper or lower half of a person's face. On one picture, the person looked happy. The other appeared angry. The dogs were then shown images of the eyes or mouths of people they had never seen before. They were also shown the left half of the faces used in training. Corsin Muller led the study. "We were really speaking, do they realize that smiling eyes have the same meaning as a smiling mouth, or angry eyes have the same meaning as an angry mouth? And it turned out that they really did perform very well in these research experiments." Once the dogs learned to recognize which image was happy or angry, they could easily find the same expressions in pictures of any face. Corsin Muller says future studies will try to show whether dogs can learn the meaning of facial expressions--for example, whether a frown shows that someone is angry. In the experiments, researchers found the dogs were slower to link a reward, or prize, with recognition of the angry face. This suggested that dogs had an idea people with angry faces were best avoided. What does the passage mainly tell us? | [

mmlu_train_32740 | People who have the habit of texting while walking tend to develop a robot-like posture, lose their balance, and involve themselves in traffic accidents, according to a research from the University of Queensland. Researchers said that text-walkers are in danger of walking into traffic and train tracks among others. They suggest pedestrians stop aside, type a text and then continue walking. For the study, the researchers tracked body movements of 26 young men and women while walking in a straight line over a distance of about 8.5 m ---once without a mobile phone, once while reading a text message and once while typing a message. They found that participants' body movements were greatly changed when they used their phone. The difference in their posture was more _ while sending a text than while reading a message. They further said that when those people began texting while walking, they slowed down their pace, went off course and moved their necks less than when reading a message. "We found that they 'locking' their arms, trunk and head together walked with a posture that was robot-like, all in aid of keeping their phone in their field of vision. So there is less movement between each of their body parts." Researcher Siobhan Schabrun said, Daily Mail UK reports. "In recent years, there have been many reports of people involved in traffic accidents because they were texting while walking. The number of pedestrian accidents is rising and texting has been blamed," Schabrun said. Despite such repeated accidents, only few studies have analyzed the impact of texting on body language. If more studies concentrate on walking styles adopted while texting, their findings can be used to lower whole accidents. While a few U.S. states have introduced laws on texting while driving, Fort Lee, a New Jersey town, went further ahead and recently fined some walkers an $85 for catching them texting. It is hoped that other American states and countries will follow. How did the researchers carry out their research? | [

While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them. The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. "Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project."

Note the word "activity". As long as you're getting your body moving, it doesn't have to mean doing difficult exercise or going to the sports hall every day. All that matters is that each week you get the right balance of activity, including aerobics , strength building, and flexibility exercise. Make exercise a habit by arranging some time every day. On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day for exercise seems like a lot of time. The good news is that it's OK to divide it into shorter exercise breaks throughout the day. Just as you might have a healthy snack to stop yourself from getting hungry, exercise snacks can keep energy levels high. So get up 15 minutes early and do some stretching activity.

Only three people have received face transplants.The world's first was carried out on French woman Isabelle Dinoire in November 2005 after she was disfigured in an attack by her dog.In 2007,her doctors reported that she had recovered slowly and steadily,overcoming two periods of rejection. In 2006,Chinese doctors performed a face transplant on a 30yearold hit by a bear.While there were some complications with tissue rejection following the operation,two years later the man was doing well,his doctors said."This case suggests that facial transplantation might be an option for _ a severely disfigured face,and could enable patients to bring themselves back into society," Shuzhong Guo and colleagues at Xijing Hospital in China wrote. A French team described their work on a 29yearold man who suffered from Von Recklinghausen disease,an illness that changes the shape of his face."The man,who was not named,was given a new nose,mouth and chin in a 2007 operation.He began to work 13 months after the transplant has more function in his face and has not rejected the new tissue," his doctors said.
