mmlu_train_47037 | Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. All of the following indicate that the monkey has almost restored to her original physical state except the fact that | [

mmlu_train_24973 | Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again. The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant pill in with the waste matter, and put the whole thing, sealed, into a special container. Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature's call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes --- with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat. The astronaut (male or female) defecates in a bag and urinates in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration, used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel. To ensure the user remains seated, the toilet comes equipped with _ | [

NASA said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle everything from sweat , the water for washing hands, shower water, water used for brushing teeth, and even urine, to make drinking water. It will save NASA millions of dollars each year. At present, each ISS astronaut uses about 4.4 liters of water every day. It costs about $24 million a year to transport water up to ISS. NASA says that a liter of water costs about $11,000. The machine will be sent to the ISS in October 2008. NASA hopes it will recycle about 93% of all water used on the station. Will the water be clean? Scientists say the wastewater will go through a very complicated process . For example, different chemicals will be put in the wastewater; the water will be heated to 130degCto get rid of bacteria .

mmlu_train_21107 | Military training has long been considered a ritual that freshmen must go through in order to officially start their college lives. While some question the necessity of such training. Many students see military training as a campus tradition that should be maintained. Early in February, the Ministry of Education issued a new regulation that colleges and universities should carry out a minimum of 14 days compulsory military training for freshmen. In a report by Beijing Evening News, Hou Zhengfang, a Beijing-based education PhD, questioned the benefits of military training. "The training routine does little to improve students' physical fitness over only two weeks' time. Maybe some disaster prevention training, such as earthquake survival or escaping from fires would be of greater benefit." Meng Yang, a 19-year-old freshman at Guangxi University, fainted during training. She said that many students, especially girls, are willing to train under direct sunshine. "For me, military training is physically challenging and even damages my health." According to Li Jian from the student affairs office of Guangzhou University, feeling dizzy happens frequently during military training and the school has received a lot of complaints from both students and parents: "But I still think military training is a good thing. Students are easier to manage after the military training. They became more positive about their new environment after the training." Although autumn is fast approaching Beijing, the noon heat burns 3300 freshmen on Tsinghua University's campus. Chu Jinjing, a freshman majoring in medicine, did feel some discomfort while training in sweaty clothes in the glaring heat, the 18-year-old still enjoyed being part of group going through strict exercises. "By going through this tough training, students bond faster and a sense of belonging to the school can be formed. I've made a lot of friends already." According to the Ministry of Education, the purpose of military training is to teach students discipline, the spirit of teamwork and endurance. But in reality, according to Xiong Bingqi, deputy director of the 21stCentury Education Research Institute, the effect is not satisfying. "Such goals require long-term development. It is unrealistic to expect military training to make a difference in only 14 days." He thus suggests that it should be up to schools to conduct military training in a way that best suits their students. However, Wang Wenhui, an 18-year-old freshman from Xi'an Jiaotong University, sees military training as a tradition that reaches beyond character building. "From junior and senior high school to college, we join military training to start a new journey. I would feel a bit incomplete without it."

mmlu_train_20256 | Over the next 20 years, we are going to send more and better robots to Mars. Those robots will send back better pictures, maps, samples, and weather reports. There is a limit to what robots can tell us, though, so eventually we will have to send people to study the planet. Before people can visit Mars, we need to invent a spaceship that can take us there. Mars is very far away. Depending on where Mars and Earth are in their orbits around the sun, it could take between six months to a year to get there. The moon is much closer, and we were there, 25 years ago. Over the next 10 years, we are going to work on building a new spacecraft that can go to the moon. Using this craft, we will practice the skills we need to go to Mars. Once we return to the moon, we are going to build a station so that people can live and work on the moon for months at a time. This is important so that we have a place to start from when we want to visit Mars, but it is also important because it gives us practice with living away from Earth. By the time you are old enough to be an astronaut, we will have people spending months on the moon. By the time you are old enough to be a commander of a space mission, we will be taking trips to Mars. By the time your kids are old enough to be astronauts, we may have people living on Mars.

mmlu_train_79564 | Do you want to live a happier, less stressful life? Try laughing for no reason at all. That's how thousands of people start their day at Laughter Clubs around the world. The first Laughter Club was started in Mumbai, India, in 1995, by Dr Madan Kataria. "Children laugh about 300 times a day. Adults laugh between 7 and 15 times a day," says Dr Kataria. "Everyone's naturally good at laughing -- it's the universal language." There are now more than 500 Laughter Clubs in India and over 1,300 worldwide. Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLS School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%. So what happens at a Laughter Club? I went along to the nearest club in the south of London to find out. I was quite nervous at the beginning of the class. I had no interest in laughing with a group of strangers, and I was worried about looking stupid . Our laughter teacher told us to clap our hands and say "ho ho ho, ha ha ha" while looking at each other. Although we couldn't tell the differences between _ laughter and real laughter, they still produced the same healthy effects. Surprisingly, it worked! After ten minutes, everybody there was laughing for real and some people just couldn't stop! At the end of the class I was shocked by how relaxed and comfortable I felt.

mmlu_train_18716 | Podcasting is like radio broadcasting, except that it uses the Internet. Anyone with a computer and a microphone can record a show about any subject. Anyone with a computer and an MP3 player can download the podcasts and listen. Podcasting does require some technical knowledge, but not very much. Many education-related podcasts are aimed at college students. But a growing number is created for, and by, students in middle school and high school. At mountain View Alternative High School in prefix = st1 /Centreville,Virginia, the students have spent several weeks preparing for their project. They have written their stories. And they have recorded music and other sound to use in their podcasts. Next, they bring together the different elements on a computer. Their teachers help by offering comments and suggestions.

mmlu_train_14230 | NASA on September 28, 2015 announced the strongest evidence yet for liquid water on the red planet, increasing the possibility that astronauts journeying to Mars could someday rely on the planet's own water for their drinking needs. You may feel like you've heard about the hunt for liquid water on Mars before--and the researchers involved know it may seem played out. But science has yet to truly prove that water flows on Mars once and for all, and doing so could completely change the way we view the planet. This new data is a big step in the right direction. "Liquid water is an attractive topic, and we like the thousandth time someone has discovered water on Mars," Lujendra Ojha, the Georgia Tech PhD candidate who led the research announced Monday, told The Post. But there's a good reason that liquid water is so "attractive": Mars is now the only planet in our solar system to show evidence of the stuff on its surface, other than _ . Other worlds have it in subsurface oceans, or scattered around as vapor in the atmosphere. But Mars is the only place where we have solid evidence for liquid that sits right there in the open air. While it would be a major leap to suggest that Mars might harbor life--even microbial life--liquid water at least makes it possible that parts of the planet are habitable. The study builds on research from April, when scientists using data from the Curiosity rover noted that the planet had the seasonal potential for liquid water. We know that because of the extremely low pressure on Mars, water has a boiling point of just a few degrees Celsius, after which it evaporates. The April study noted the presence of perchlorates --a kind of salt--which could make the boiling point of Mars' water much higher, theoretically allowing it to remain liquid. They affirmed that the planet's temperature would be right for liquid, perchlorate-filled water to form every day during winter and spring. The best title for the passage can be " _ ". | [

mmlu_train_62281 | A sense of humor is just one of the many things shared by Alfred and Anthony Melillo, 64-year-old twin brothers from East Haven who made history in February 2002. On Christmas Eve, 1992, Anthony had a heart transplant from a 21-year-old donor. Two days before Valentine's Day in 2002, Alfred received a 19-year-old heart, marking the first time on record that twin adults each received heart transplants. "I'm 15 minutes older than him, but now I'm younger because of my heart and I'm not going to respect him," Alfred said with a big smile, pointing to his brother while talking to a roomful of reporters, who laughed frequently at their jokes. While the twins knew that genetics might have played a role in their condition, they recognized that their eating habits might have also contributed to their heart problems. "We'd put half a pound of butter on a steak. I overdid it on all the food that tasted good, so I guess I deserved what I got for not dieting properly." The discussion moved to Anthony's recovery. In the five years since his heart transplant, he had been on an exercise program where he regularly rode a bicycle for five miles, swam each day, and walked a couple of miles. He was still on medication, but not nearly as much as Alfred, who was just in the early stage of his recovery. "Right now I feel pretty young and I'm doing very well," Anthony said. "I feel like a new person." Alfred said his goal, of course, was to feel even better than his brother. But, he added, "I love my brother very much. We're very close and I'm sure we'll do just fine."

mmlu_train_46989 | A recent report has suggested that air pollution in our big cities could be as damaging to our health. The report put forward practical tips that city people can take to reduce their exposure to city air pollution. Quite a lot, it turns out. * Watch where you walk Avoid walking along busy streets and thoroughfares , instead choosing side streets and parks. because pollution levels can fall by a factor of 10 just by moving a few metres away from the main source of the pollution - exhaust fumes. " Don't walk behind smokers, and walk on the windward, side of the street where exposure to pollutants can be 50% less than on the leewardside. * Pavement sense When you're crossing a road, stand well back from the kerb while you wait for the lights to change. Every metre really does count when you are close to traffic. As the traffic moves, the gases can disappear in just a few seconds, particularly if the wind is up, which means holding your breath during this period can make a difference, silly as that might sound. Besides, cross the road as quickly as possible. And once you're over, continue along the pavement as far away from the kerb as possible. * Where to sit on the bus Sitting on the driver's side of a bus can increase your exposure by 10% compared with sitting on the side nearest to the pavement. And sitting upstairs on a double-decker can reduce your exposure too. It's difficult to say whether travelling on an underground train is better or worse than taking the bus, but the air pollution on underground trains tends to be less toxic by weight than that found at street level. * Wear a mask Masks can be a good thing, but they only make a difference if they fit tightly and are cleaned regularly. Even the slightest gap to allow you to breathe more easily will _ any advantages. Worse, if you fail to clean or change the mask regularly, something dangerous can form on the mask. So the air you breathe is dirtier rather than cleaner. Which of the following is the author's opinion according to the passage? | [

mmlu_train_29335 | Dyslexia is a learning disorder, it interferes with the ability to recognise words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United State. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order. But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games. Vanessa Harrar of Britain's University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. Doctor Harrar calls this a " _ shifting of attention across the senses." "So, if you are trying to read something and then trying to listen to somebody who's reading aloud and you're trying to follow along with what they are reading -- they have to switch their attention from hearing what they are saying to looking at the piece of paper and back again. So we found they have quite sluggish shifting of attention across the senses," said Harrar. In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time. Doctor Harrar feels like playing action video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly. "Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly," said Harrar. The study also shows that dyslexic people have the most difficulty going between what they saw and what they heard, this may have an effect on how dyslexic children are taught how to read. When children learn the alphabet,they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it. Why can playing video games help dyslexic people learn more quickly? | [

The university of the past is not like the university of the present and the university of the present will not be like the university of the future. This "adaptation" to the times is what can make some universities great or make some universities among the worst in the nation. In the past the university was very set in their ways. They did things the way they wanted them done. They paid no attention to the rest of the society and the way the ones paying the bills wanted them done. In the past the professors would lecture endlessly to the students, which often left the students bored and with no idea what was really said to them in the lecture. This is no way to try and teach students; students need interaction with the professors that are paid to teach them. As Paulo Freire believed there needs to be communication between the students and the professors and the class should not be totally memorization. This is the way that things were done in the past. In the present many universities have either changed or are changing the way that they run their universities. The universities now are taking on many of the modern educational beliefs in order to make changes in the teaching methods. Universities are breaking down many of the divides between majors that they offer. By breaking these barriers the universities are becoming less specialized and more diverse. This goes along with the ideas of Berry who believes that the schools are over-specialized and that the universities are now just machines that are merely meant to produce workers. In the past few years the colleges have been lowering the standards of admission, which in turn lowers the standards of all the schools below the college level.

mmlu_train_40942 | Everyone is familiar with white fat, which serves as an energy warehouse. Many mammals also have brown fat, which has the unique ability to produce heat. Brown fat is sometimes mistaken for a type of gland , which it resembles more than white fat. It varies in color1 from dark red to tan. When the animal is exposed to a cold environment, the color1 darkens. In contrast to white fat, brown fat has numerous nerves which provide sympathetic stimulation to the fat cells. Brown fat is most noticeable in newborn animals, wrapped round the central organs to keep them warm. In human infants it occupies up to 5% of body weight, then declines gradually. Certain quantities of brown fat can be discovered in adult humans, especially when they are exposed to cold temperatures. Most of brown fat in adults is located in the lower neck. Exposure to cold leads to sympathetic stimulation of brown fat cell. As in white fat, sympathetic stimulation promotes hydrolysis of triglyceride , with release of fatty acids. In contrast to other cells, including white fat cells, brown fat cells express UCP1, which gives the cell's mitochondria an ability to produce heat rather than ATP. Within brown fat cells, most fatty acids are immediately combined with oxygen in mitochondria and a large amount of heat is produced. There is only about 50g of brown fat in the neck region and it switches on and off throughout the day as it's exposed to different temperatures or if you exercise or eat. But this capacity is much greater in young children compared with adolescents and adults. The challenge is now to use the knowledge to find out what might switch on brown fat. If it is switched on, we can benefit from it. Brown fat produces lots of heat by burning calories. Unlike white fat, brown fat does not expand our ageing waistlines. And that's why the race is on to find out more about brown fat, and how humans could use it to our advantage, though we would waste energy unnecessarily, and we would sweat a lot and forever be opening windows.

mmlu_train_40481 | A report by the Consumer Electronics Association says electronics are among the most popular gifts being bought this holiday season. Jim Barry is a spokesman for the Consumer Electronics Association. He says the CEA study found that electronics represent three of the top five things on its "holiday gift wish list" this year. JIM BARRY: "Notebook computers are at the top, followed by iPads and then e-readers. IPad is a touch-screen tablet computer and that's really the big player in that category." The computer company Apple began selling its small, touch-screen computers in April. People use the touch-screen computers to surf the Web, write e-mails, watch movies and read books. Since the iPad's release earlier this year, several other companies have come out with their own tablet computers just in time for Christmas. A report from the e-Marketer research group predicts that worldwide, tablet sales will reach more than eighty-one million in two thousand twelve. Still, Jim Barry says these devices are facing tough competition this year from another Christmas favorite. JIM BARRY: "Another hot category right behind that are the e-readers. So you can read on an iPad or a touch-screen tablet, but the e-book readers are less expensive. The Kindle is the market leader there, from Amazon. But you also have the Nook from Barnes and Noble and the e-reader from Sony. And you have more and more of those e-readers coming into the market as well." The Consumer Electronics Association report found that iPod music players are also in high demand this holiday season. But not all of the things on the holiday gift wish list involved electronics. Clothes, cars and motorcycles also made the list. So did family togetherness and good health. And the one thing that people wanted most? JIM BARRY: "At the top of the list was peace and happiness."

mmlu_train_61277 | Cowboy or spaceman? A dilemma for a children's party, perhaps. But also a question for economists, argued Kenneth Boulding, a British economist, in an essay published in 1966. We have run our economies, he warned, like cowboys on the open grassland: taking and using the world's resources, confident that more lies over the horizon. But the Earth is less a grassland than a spaceship--a closed system, alone in space, carrying limited supplies. We need, said Boulding, an economics that takes seriously the idea of environmental limits. In the half century since his essay, a new movement has responded to his challenge. "Ecological economists", as they call themselves, want to revolutionise its aims and assumptions. What do they say--and will their ideas achieve lift-off? To its advocators, ecological economics is neither ecology nor economics, but a mix of both. Their starting point is to recognise that the human economy is part of the natural world. Our environment, they note, is both a source of resources and a sink for wastes. But it is ignored in conventional textbooks, where neat diagrams trace the flows between firms, households and the government as though nature did not exist. That is a mistake, say ecological economists. There are two ways our economies can grow, ecological economists point out: through technological change, or through more intensive use of resources. Only the former, they say, is worth having. They are suspicious of GDP, a crude measure which does not take account of resource exhaustion, unpaid work, and countless other factors. In its place they advocate moreholistic approaches, such as the Genuine Progress Indicator (GPI), a composite index that includes things like the cost of pollution, deforestation and car accidents. While GDP has kept growing, global GPI per person peaked in 1978: by destroying our environment we are making ourselves poorer, not richer. The solution, says Herman Daly, a former World Bank economist and eco-guru, is a "steady-state" economy, where the use of materials and energy is held constant. Mainstream economists are unimpressed. The GPI, they point out, is a subjective measure. And talk of limits to growth has had a bad press since the days of Thomas Malthus, a gloomy 18th century cleric who predicted, wrongly, that overpopulation would lead to famine. Human beings find solutions to some of the most annoying problems. But ecological economists warn against self-satisfaction. In 2009 a paper in Nature, a scientific journal, argued that human activity is already overstepping safe planetary boundaries on issues such as biodiversity and climate change. That suggests that ecological economists are at least asking some important questions, even if their answers turn out to be wrong. Which in the following will the author probably agree? | [

The crew could be in danger! Ten minutes later, Mission Control sent an all-clear order. The station and crew were safe. Leftover Litter More than 1,600 pieces, large and small, became space junk. There are other kinds of space trash, too. Astronauts drop tools. They lose screws and drop gloves. Even chipped paint can become space junk. So can regular trash that's tossed from space stations. Small Scraps, Big Damage All this trash can cause problems. Litter that's orbiting Earth can travel at 7.7 kilometers (about 5 miles) per second. That's fast! No wonder space junk can crack windows, chip heat shields,3 and rip solar panels. Sometimes space junk falls to Earth. Friction with particles in Earth's atmosphere causes most junk to burn up. Really big pieces slam into the ground. Some splash into oceans. That's why scientists track space junk. They use radar and telescopes. These tools can track objects larger than a grapefruit. Millions of pieces are much smaller than this. These small pieces can do big damage. Yet there is no way to track them. Scientists are thinking of ways to clean up space. One way is to shoot lasers at space trash. The lasers would push the litter farther away. The only problem is Earth's gravity would eventually pull it back. It would become a problem again later. Here's another way. Make spacecrafts with giant nets. The nets would catch the litter. Then the litter could be dumped into Earth's atmosphere. The litter would burn up.

mmlu_train_15667 | First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be done as quickly as possible. In the case of the seriously injured, a few minutes can make the difference between complete recovery and loss of life. First-aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal injury and paralysis . Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person's family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim. First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim's condition is known by the acronym ABC, which stands for: A---Airway: is it open and clear? B---Breathing: is the person breathing? Look, listen, and feel for breathing. C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems.

A team of psychologists in Toronto created a strategy of cognitive training to help people preserve these abilities."Our primary emphasis was on improving the use of general strategic abilities because they are particularly weak to the aging process,"Dr.Donald Stuss,director of the study,said in a press release.The team examined 49 healthy older adults with normal cognitive decline.All of the participants were between the ages of 71 and 87.Over the course of 12 weeks,psychologists taught them methods to improve their strategic abilities.Afterwards,researchers saw a 15 to 40 percent improvement in the memories of all participants."Over a period of six months their improvement not only maintained,but increased,"said Dr.Gordon Winocur,coordinator of the study.The 12-week course was broken up into three four-week sections,focusing on a different skill involved in strategic abilities:memory,goal management and psychosocial function. The memory training emphasized how to preserve and recover information, while goal management focused on methods to lower the chance of memory slips.Psychosocial training was aimed at increasing the participants' confidence in their mental abilities. "We wanted to develop a cognitive training program that would produce improvement over a ly short period of time,so participants could benefit more on that while they're still functional and slow down the rate of decline,"said Winocur."If we can work with people in the early stages of cognitive decline,then we can slow down the rate of this decline and help them maintain a higher level of function for a longer period of time."

mmlu_train_12922 | The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland. Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation. JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers." For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident. Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water. JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables." The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean. JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of _ . So the concentration of radioactivity in the seawater would still be quite low." Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says. Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry. A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths. The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen. To get the latest updates, go to www.unsv.com.

These decisions can include choosing therapies and schools, as well as finding financial help for hearing aids or cochlear implants . Help Me Hear Foundation is a public charity that gives the gift of hearing to deaf children from families existing on very low incomes around the world. Help Me Hear Foundation believes that a child's first years of development are critical. Being able to hear is vital to human, and Help Me Hear Foundation seeks to provide a positive lasting impression on society through its programs. Recipients of Help Me Hear Foundation's benefits receive state-of-the-art hearing devices that otherwise would cost thousands of dollars per child over the course of their lifetime. The Foundation raises money through donations for hearing aids and cochlear implants, which saves recipients and their families on average over $50,000 on related expenses. The Foundation tries to be a transparent charity, and wants to be a catalyst for allowing deaf and hearing-impaired children to develop in a typical fashion alongside their peers. Needy families can obtain information on specific services, and find out about deafness education by visiting the Help Me Hear Foundation's website. The website offers helpful information on how hearing aids work, and how hearing aids ease many of the learning and language challenges that hearing-impaired children deal with on a daily basis.

mmlu_train_16731 | Does your pet have a slim figure? According to the Association of Pet Obesity Prevention (APOP), about half of all dogs and nearly 60% of all indoor cats are overweight. Larry Kornegay, president of the American Veterinary Medical Association, says he sees an overweight pet nearly every day, and unusually the owner is overweight. So talking about the topic can be _ . "I talk about their pet's health. Still, some clients take it personally." Here are some tips for pet weight loss: See the vet . Have your vet put together a plan and treat any existing medical problems. Pain relief and diet changes may be required for arthritic pets, which will allow for exercise to at least begin. Skip the crash diet (an attempt to lose weight quickly by strictly limiting the diet). A special weight-loss diet may be suggested. For example, look for the supplement which burns fat and builds muscle mass in foods. Never place any pet on a crash diet, especially cats, which can suffer a potentially fatal liver disease as a result. There's a safe weight-loss drug for dogs you can ask your vet about. Dine alone. "Cut out treats and resist temptation by keeping pets out of the room you're dining in," says Chicago vet Sheldon Rubin. You can buy low-calorie treats for dogs and cats. Rubin also recommends mini carrots, small apple slices or blueberries for dogs. What's important is finding other ways, aside from food, to show your love. Play with your cat using an interactive toy, and take your dog for walks. Walks are great for bonding, and good for you. Studies show people are actually more willing to lose weight themselves if it also will help their pet. Feed pets at special times. Pre-measure food carefully--don't give them a larger meal than ever--and leave it in various places, so pets sniff it out and use the stairs. It's fun, and it's good exercise. .

A NASA satellite called QuikSCAT has discovered highways of wind over the Earth's oceans.Scientists believe these invisible roads may explain why many nonflowering plants,such as mosses and lichens ,grow where they do. The satellite is able to send microwaves from space to the surface of the ocean.The pattern of signals that come back shows which way the winds are blowing. Using this _ , the scientists studied a group of islands in the southern hemisphere ,near Antarctica.Winds tend to blow anticlockwise in this region,but there are lots of local differences. When the researchers compared these local patterns to botanical data,they found that the wind had an important effect on where species of mosses,lichens,and other nonflowering plants grow. For example,Bouvet Island and Heard Island,share 30 percent of their moss species,29 percent of liverworts ,and 32 percent of lichens-even though they are 4,430 kilometers apart.In contrast,Gough Island and Bouvet Island,separated by just 1,860 kilometers of sea,share only 16 percent of mosses and 17 percent of liverworts.They have no lichens in common. Ferns and flowering plants don't travel as well in the wind,so they don't show the same kinds of distribution patterns. This story is about_. | [

mmlu_train_10645 | A new report said scientists may not be far from giving apes the ability to think and talk like humans. The report is about experiments which transplant human cells into animals for medical purposes. It claimed that concerns about the creation of talking apes should be taken seriously. It should also draw people's attention to the possibility that the medical research about creating "humanised" animals is going to generate monsters. A regulatory body is needed to closely monitor any experiments that many risk creating animals with human-like consciousness or giving them any appearance or behavioural traits that too closely resemble humans, the report said. Scientists would, for example, be prevented from replacing a large number of an ape's brain cells with human brain cells until more is known about the potential risks. This has already been done in simpler animals like mice, which is judged to be less risky. Under the new UK guidelines, the power to regulate tests on animals containing human material would be transferred to a body with wider responsibility for animal testing in the Home Office. While there is no risk from experiments currently being carried out in Britain, it is possible that ethical boundaries could be crossed within the next few years if scientists are not careful, the experts said. Professor Thomas Baldwin, a member of the Academy of Medical Sciences working group that produced the report, said the possibility of humanised apes should be taken seriously. He said, "The fear is that if you start putting very large numbers of human brain cells into the brains of primates you might transform the primates into something that has some of the abilities that we regard as distinctly human, such as speech, or other ways of being able to _ or relate to us." Professor Martin Bobrow, chair of the academy working group that produced the report, said, "The very great majority of experiments present no issues beyond the general use of animals in research and these should continue to proceed under the current regulations." Lord Willis, chair of the Association of Medical Research Charities, said, "AMRC only supports research that is absolutely necessary and where no suitable alternative methods are available."

mmlu_train_64580 | Recently, a study showed that changes found in astronauts' eye tissue might cause vision problems, and possibly even blindness. As well as threatening the health of astronauts, this could influence long-distance missions into space. Larry Kramer of Texas Medical School in Houston and his colleagues carried out MRI scans on 27 NASA astronauts after they had spent an average of 108 days in space. About half of them had some problems in their optic nerve or eyeball. The changes match those seen in people with idiopathic intracranial hypertension, a rare condition in which the pressure of blood is abnormally high in the brain. People with the condition experience headaches, nausea and vision problems including blindness. In space, the changes are probably caused by living in free fall. "It is not because of the sunlight in space or the spacecraft's function," says Kramer. "One likely reason is that blood which normally pools in the legs is shifted toward the skull , raising pressure." The findings are similar to the results of a survey of 300 astronauts carried out in 2011. The damage in vision was reported by 29 percent of astronauts on short-term missions, and 60 percent on long-term missions. "If astronauts are exhibiting these changes after only 100 days in space, what will happen on a three-year flight to Mars?" asks Jason Kring, who studies human performance in extreme conditions at the Embry-Riddle Aeronautical University in Florida. "Deteriorating vision could seriously damage astronauts' ability to carry out routine mission tasks, including monitoring displays and navigating the rocky landscape of Mars," says Kring. "This possibility, combined with what we already know about how micro-gravity affects muscles and bones, paints a dark future for human space flight unless we start to develop effective measures." Kramer says that NASA has the matter in hand. In the wake of the study, all astronauts now have regular brain scans. This includes those yet to travel into space, providing a baseline from which any changes would be obvious. He also believes it might be possible to identify astronauts' risk of eyesight damage from medical data before sending them into space. What is the main idea of the passage? | [

mmlu_train_33095 | Dyslexia is a problem that restricts the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves areas of the brain that process language. Brain scientists are studying whether they can predict which young children may struggle with reading to provide them with early help. John Gabrieli at the Massachusetts Institute of Technology is leading the study of five-year-olds in about twenty schools in the Boston area. They studied in the schools with kindergartens. And for all the children joining in the study, they give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read. So far, fifty of them have been examined in a scanner, a special machine, to show brain activity. Written tests are not always able to identify dyslexia or other problems, while brain scans may offer a more scientific way to identify problems. And with reading problems, early identification is important. When it comes to helping children overcome reading difficulties, the younger the child, the more effective they are. Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers, the less treatment can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science have textbooks. While the children are given tasks related to reading, the brain scans measure the extent to which certain parts of the brain become active while the children do the work. The scientists say they are pleased with early results from the study, but have a long way to go.

Fructose,found naturally in honey and fruit,is used widely in foods ranging from soft drinks to yogurt.But while its sweet taste is popular,the sugar could cause wrinkles,the researchers said.Dr.Moshe Werman and Boaz Levi of the Technion-Israel Institute of Technology fed large amounts of fructose to laboratory rats.Writing in the Journal of Nutrition,they said the fructose-fed rats showed changes in the collagen of their skin and bones.Collagen basically holds the body together.The loss of collagen is what causes loose skin and deep wrinkles in older people. The process affected,Werman's team said,is known as"cross-linking "."Too much cross.1inking makes the skin stiff, and these are the conditions that encourage wrink1ed skin,"Werman said in a statement.He said the same could be true of people,although this has not been shown."Americans are eating more and more processed foods such as baked goods,canned fruits,jams is and dairy products that contain fructose,"Werman said.Other studies have shown that taking in high fructose may cause diabetes . The rats Werman worked with were fed much more than the average adult person might eat in a day,which is standard in such experiments.The rats were fed 12.5 grams of fructose per kg of weight everyday for a year.

mmlu_train_27520 | Elderly people are growing healthier, happier and more independent, say American scientists. The results of a 14-year study to be announced later this month reveal that the diseases associated with old age are affecting fewer and fewer people and when they do suffer a stroke , it is much later in their life. In the last 14 years, the National Long-term Care Survey has gathered data on the health and lifestyles of more than 20,000 men and women over 65. Researchers, now analyzing the results of data gathered in 1994, say arthritis, high blood pressure and circulation problems -- the major medical complaints in this age group -- are troubling a smaller proportion every year. And the data confirms that the rate at which these diseases are declining continues to increase. Other diseases of old age -- dementia, strokes, arteriosclerosis and emphysema -- are also troubling fewer and fewer people. "It really raises the question of what should be considered normal ageing," says Kenneth Manton, a demographer from Duke University in North Carolina. He says the problems doctors accepted as normal in a 65-year-old in 1982 are often not appearing until people are 70 or 75. Clearly, certain diseases are beating a retreat in the face of medical advances. But there may be other contributing factors. Improvements in childhood nutrition in the first quarter of the twentieth century, for example, gave today's elderly people a better start in life than their former generations. On the downside, an increase in some cancers and bronchitis may reflect changing smoking habits and poorer air quality, say the researchers. "These may be subtle influences," says Manton, "but our subjects have been exposed to worse and worse pollution for over 60 years. It's not surprising we see some effect." One interesting correlation Manton uncovered is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their education live an extra seven years. Although some of this can be attributed to a higher income, Manton believes it is mainly because educated people seek more medical attention. The survey also assessed how independent people over 65 were, and again found a striking trend. Almost 80% of those in the 1994 survey could complete everyday activities ranging from eating and dressing unaided to complex tasks such as cooking and managing their finances. That represents a significant drop in the number of disabled old people in the population. According to Manton, slowing the trend has saved the United States government's medicare system more than $200 billion, suggesting that the ageing of America's population may prove less of a financial burden than expected. But independence can have drawbacks. Scientists found that elderly people who felt emotionally isolated maintained higher levels of stress hormones even when asleep. The research suggests that older people live best when they feel independent but know they can get help when they need it. Which of the following is NOT considered as a contributor to elderly people getting healthier? | [
