mmlu_train_23483 | Every year seals would crowd ashore in Farne Island and give birth to their pups. Between early October and early December, 1,500 seal pups will be born. Almost half of them will not make it past the first three weeks of life. "The pups have to stay out of the water for the first three weeks, when they have their white coat, which is not very waterproof," explains the warden ,who spends nine months on the Island. "But when you're born in November on a rock in the North Sea, it's a tough start to life," he said. Storms often wash young pups into the water. And occasionally, young, inexperienced mothers abandon their pups and head out to sea. "We lost 41% last year," said David Steel, the National Trust's head warden on the Farne Islands. "Mother Nature certainly keeps them in check." Despite the early challenges for every newborn seal, the population is healthily and slowly and steadily growing. There are almost 4,000 seals on a set of islands, which is named a Special Area of Conservation(SAC), meaning it is protected under EU regulations. This successful human safeguarding of the seals' habitat is huge turnaround . Just a few decades ago, the seal population was deliberately _ The animals used to be thought of as a threat to local fish stocks. During the late 1960s and 1970s, thousands of seals were shot in a cull that aimed to protect the local fishing industry. According to the National Trust, between 1962 and 1983 approximately 2,000 adult females and 3,000 pups were shot. But, as the fishing industry collapsed, it was gradually replaced by tourism. Today, several companies use fishing boats to take groups of people to visit the islands and admire the scenery, seabirds and, of course, the seals that make their homes in this bleakly beautiful place.

mmlu_train_10272 | BEIJING,Feb.5,2013(Xinhua)-Chinese health authorities on Tuesday launched a campaign to fight against assisted reproductive technology (ART:) abuse.Unauthorized ART use,surrogate motherhood and the illegal collection and supply of sperm and eggs,as well as the illegal sale and abuse of ovulation induction medicine,will be targeted. The Ministry of Health and health department of the People's Liberation Army General Logistics Department jointly announced the campaign at a conference.Both departments also ordered all of their local branches to _ permits for new organizations that wish to offer ART treatments.That is,new organizations will not appear recently.Official figures showed that at the end of 2012,China had 358 organizations authorized to conduct ART treatment. The health ministry also delivered a brief statement of the country's current infertility rate and ART use.The infertility rate in China is now between 7 and 10 percent,the ministry said.Some 70 to 80 percent of women who are suffering from infertility can be pregnant after changing their lifestyles and receiving medical treatment.Around 20 percent of infertile couples have to resort to ART to have babies.In 2011,about 350,000 people received ART treatment and more than 60,000 infertile couples successfully had children with the help of ART,the ministry said.

mmlu_train_23711 | LONDON--Here's a new warning from health experts:Sitting is deadly. Scientists are increasingly warning that sitting for long periods--even if you also exercise regularly--could be bad for your health.And it doesn't matter where the sitting takes place--at the office,at school,in the car or before a computer or TV--just the overall number of hours it occurs.Several studies suggest people who spend most of their days sitting are more likely to be fat,have a heart attack or even die. In an editorial published this week in the British Journal of Sports Medicine,Elin EkblomBak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define physical activity to highlight the dangers of sitting. While health officials have issued guidelines recommending minimum amounts of physical activity,they haven't suggested people try to limit how much time they spend in a seated position. "After four hours of sitting,the body starts to send harmful signals,"said EkblomBak.She explained that genes regulating the amount of glucose and fat in the body start to shut down. Even for people who exercise,spending long periods of time sitting at a desk is still harmful.Tim Armstrong,a physical activity expert at the World Health Organization,said people who exercise every day--but still spend a lot of time sitting--might get more benefit if that exercise was spread across the day,rather than in a single bout . Still,in a study published in 2009 that tracked more than 17,000 Canadians for about a dozen years,researchers found people who sat more had a higher death risk,whether or not they exercised. "We don't have enough evidence yet to say how much sitting is bad," said Peter Katzmarzyk of the Pennington Biomedical Research Center in Baton Rouge,who led the Canadian study."But it seems the more you can get up and interrupt this sedentary behavior,the better." Figures from a U.S. survey in 20032004 found Americans spend more than half their time sitting,from working at their desks to sitting in cars. Experts said more research is needed to figure out just how much sitting is dangerous,and what might be possible to _ those effects. "People should keep exercising because that has a lot of benefits," EkblomBak said."But when they're in the office,they should try to interrupt sitting as often as possible," she said.

If we are to solve the nursing shortage. hospital administration and doctors everywhere would do well to follow Beth Israel's example . At Beth Israel each patient is assigned to a primary nurse who visits at length with the patient and constructs a full-scale health account that covers everything from his medical history to his emotional state. Then she writes a care plan centered on the patient's illness but which also includes everything else that is necessary. The primary nurse stays with the patient through his hospitalization. keeping track with his progress and seeking further advice from his doctor. If a patient at Beth Israel is not responding to treatment. it is not uncommon for his nurse to propose another approach to his doctor. What the doctor at Beth Israel has in the primary nurse is a true colleague. Nursing at Beth Israel also involves a decentralized nursing administration; every unit is a self-contained organization. There are nurse-managers instead of head nurses; in addition to their medical duties they do all their own hiring and dismissing, employee advising, and they make salary recommendations. Each unit's nurses decide among themselves who will work what shifts and when. Beth Israel's nurse-in-chief ranks as an equal with other vice presidents of the hospital. She is also a member of the Medical Executive Committee. which in most hospitals includes only doctors. The main difference between a nurse-manager and a head nurse is that the former | [

mmlu_train_27079 | In late summer or early fall the large, yellow seed heads of sunflowers will be ripening. If gardeners can keep off the birds and other wildlife trying to eat the seeds, they can have a large harvest. The bright yellow blooms will make a rainbow garden, brightening up any space. However, planting the sunflower seeds is a skilled job. Plant seeds no deeper than the full length of itself. Smaller sized sunflowers can be spaced a foot apart. Larger varieties will need to be spaced as far apart as three feet. This allows ripe plants enough space for the seed heads to ripen without knocking the ripe seeds off before gardeners have a chance to harvest them. Most sunflower seeds, especially those with eatable seeds, are large enough to handle without the need for seed sorters. This is why sunflowers make an excellent choice for a children's garden as well. Gardeners will want to mix plenty of soil fertilizers into the ground as sunflowers tend to be heavy feeders. Sunflowers can be slow starters and the tiny new plants don't seem to grow very rapidly. Gardeners should protect the new plants as they begin to grow. Once they get going, sunflowers are able to _ many weeds, making them easier to grow in the home vegetable garden than many other plants. Most pests and diseases are not a bother to the sunflower, however, more than one gardener has said that their lovely looking plants were destroyed overnight by hungry squirrels, mice or birds. To preserve their harvest, gardeners can cover the ripening seed head with stockings or net cloth to help keep the destroyers off the seeds. Planting sunflower seeds is easy and can help even the smallest gardener feel successful in their gardening attempts. Why should enough space be left between sunflowers? | [

mmlu_train_60347 | The European Union announced plans on Tuesday to temporar-ily ban the use of animal cloning for food production, while allowing imports of food derived from the offspring of clones from the United States and elsewhere. The report from the European Commission followed a call by EU lawmakers in July for a total ban on food derived from cloned animals and their traditionally bred offspring, citing ethical concerns over the industrial production of cloned meat. The Commission said a temporary five-year EU ban on cloning for food production was justified on animal welfare grounds, but said banning imports of food from the offspring of clones was unnecessary and would disrupt global trade. "Food from cloned animals is safe. In fact, the scientific opinion is that it cannot be differentiated in any way from food normally bred animals. The issue is animal welfare," EU Health and Consumer Commissioner John Dalli told reporters. Food derived from the offspring of clones presents no such animal welfare issues, and banning its sale and import would be impossible because the origin is untraceable, Dalli said. "Such a prohibition would lead to a ban of imports of any food of animal origin (meat, milk and processed products)from third countries allowing the cloning technique," the report said. "We're not going to regulate for the world," Dalli added. But animal welfare groups criticized the Commission's decision, saying it had bowed to pressure from third countries. "We do not accept the Commission's position that it would be impossible to enforce a ban that includes the offspring of cloned animals, as (other) meat traceability systems are already in place," said Sonja Van Tichelen, director of the Eurogroup for Animals.

This means users can have highspeed Internet access and enjoy video and CDquality music on their phones. "Mobile data is not a dream; it's not an option but a requirement." said Len Lauer, head of a US communications company,Sprint PCS,at a 3G conference in Bangkok earlier this month. With 3G, you can forget about text messages telling you yesterday's news; a 3G phone can receive video news programs, updated four times a day. Internet access will also be much quicker, making it easier to surf the Web on your phone than on your computer at home. Facetoface video calls And don't worry about getting lost. 3G phones offer map services so you can find a new restaurant just by pressing a few keys on your handset. However, the most impressive part of 3G technology is video calling. With live twoday video communication, you can have facetoface talks with friends and family on your mobile phone. Many European countries have already launched the service. In May 2000 the US Government issued five licenses to run 3G wireless services, while the first 3G phones arrived in Italy in March this year. International telecom companies can't wait to sell 3G in China, the world's largest mobile telecommunications market. But they will have to be patient. At the moment, China is busy testing its 3Gbased technologies, networks and services. This will be followed by a trial period before the phones can finally hit the shops. "We need to create a pool of 3G customers before the largescale commercial launch of the service." said Fan Yunjun, marketing manager for Beijing Mobile.

The reality,however,is that most of us organize their time around work demands,school deadlines,commuting or social events.Doing whatever your body feels like doing is a luxury in today's fast-paced modem society. But that doesn't mean it isn't worth trying.Obeying our body clock has significant health benefits.Disrupting our natural body rhythm,on the other hand,has been linked to problems such as depression,obesity,or headache,says Steve Key,a biology professor. When the body clock can synchronize(......)the rhythms of its natural processes,it "gives us an advantage in daily life",says Key. According to him,when it comes to cognitive work,most adults perform best in the late morning.As our body temperature starts to rise just before awakening in the morning and continues to increase until midday,our memory,alertness and concentration gradually improve. However,he adds,our ability to concentrate typically starts to decrease soon thereafter.Most of us are more easily distracted between noon and 4 pm. Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm,making that a good time for a nap. Surprisingly, tiredness may increase our creative powers.For most adults,problems that require open ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning. When choosing a time of day to exercise,paying attention to your body clock can improve results.Physical performance is usually best from about 3 to 6 pm,says Michael Smolensky,a professor of biomedical engineering. Of course, not everyone's body clock is the same,making it even harder to synchronize natural rhythms with daily plans. Inspiration to solve a difficult problem will most probably come to us _ . | [

Meanwhile, at the same time in Antarctica , snow covers the land. A group of emperor penguins crowd together to keep warm, using stop-and-go movements to protect themselves from the winds. Can you see the connection? Emperor penguins move like cars in traffic jams to keep warm, that's according to new research by the Alfred Wegener Institute, Helmholtz Center for Polar and Marina Research in Germany. A penguin only needs to move 2cm in any direction for its neighbor to do the same thing. These movements then flow through the whole group of penguins like a "traveling wave". These waves also help smaller crowds join bigger groups, keeping more and more of their friends warm. A single Antarctic "traffic jam" has thousands of penguins. Interestingly, the technology used for studying road traffic jams was used to study the penguins. This included studying time-lapse videos. Scientists also discovered that unlike on the road, these waves can be made by any penguin and in any direction. With temperatures usually dropping below -50degC, and winds reaching speeds of up to 200km/h, these traveling waves are very important for penguins to keep warm. These penguins can also teach us a lesson. In big groups, they learn to be orderly and patient, and to never crash into each other.

mmlu_train_48998 | A high school in Hiroshima City has been the first to do something with DNA in the world. Its students have won praise not only for doing this research but also for presenting their findings to groups of expert scientists. The school is one of the Super Science High Schools allowed by the Ministry of Education, Culture, Sports, Science, and Technology, where students are given an opportunity to study science at an advanced level. Here, students use the same type of hitech experimental laboratories as those found at universities. In these labs, they conduct experiments and research in new fields of study not found in textbooks. As part of this science course, the students, with the help of Hiroshima University, used a machine called sequencer , and over the course of a year and a half they succeeded in decoding the DNA. They then presented their results to academic groups. Achieving a world first might sound very wonderful, but the process of decoding the DNA involved very hard work. The students were also responsible for maintaining the equipment, and they had to read difficult research papers and put in extra study beyond their regular schoolwork. "Researchers need to work hard. The work was tiring, but the students worked toward their ambitious goal of achieving a world first. They have a great sense of achievement, and the number of students who hope to become biologists has increased," said Taruma Akinori, who is in charge of the science course. In addition to the results being added to the scientific community, the students' research paper will be translated into English and made available overseas. Moreover, the students have decided to take on a new challenge in DNA decoding. The author's attitude towards those students who have accomplished a world first in DNA decoding is _ . | [

mmlu_train_37092 | As a published author with a degree in English, 33-year-old Tom Williams has achieved more than many people will in a lifetime. What makes those achievements more impressive is that he's dyslexic. At school Tom, who has worked as a literary agent and now has a full-time job with a digital publishing company, would often find keeping up in lessons so tiring that he would fall asleep. "I found it quite frustrating that everybody else had neat handwriting and could spell and I just couldn't do what they could," says Tom, who has written a respected biography of crime writer Raymond Chandler. It wasn't until the age of 17 that he was given a test for dyslexia that showed why he'd struggled for so long. He was always studying for A-levels including English. "My teacher didn't think I'd get the grades I was capable of," he says. "So she pushed for me to be tested and I'm grateful that she did." Until his diagnosis Tom had been ranked somewhere in the middle of his classes at school. He couldn't understand why assignments would come back covered in red ink. However, after Tom's diagnosis, when his condition began to be taken properly into account, he found himself at the top of the class. To study English well, he wrote down new words as he came across them and tried to find somewhere quiet and well lit to read and write. He says people were often surprised that someone with dyslexia wanted to pursue a degree in English. Similarly, when he went to study at University College London, the tutors were initially taken aback at his degree choice. Not everyone understands dyslexia so well. "If teachers aren't trained to recognize signs of dyslexia, they'll think children are less able," he says. To make sure that doesn't happen and to encourage a deeper understanding of the condition among those affected by it, Tom becomes a supporter of the charity Dyslexia Action.

mmlu_train_41966 | Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which reduces strength and increases the possibility of falls and fractures . New research is showing how this happens and what to do about it. A team of Nottingham researchers has already shown that when older people eat, they cannot make muscle as fast as the young. Now they've found that the ability to prevent muscle breakdown is reduced with age. When older people eat, they don't build enough muscle with the protein in food; also, the insulin fails to shut down the muscle breakdown that rises between meals and overnight. Normally, in young people, insulin acts to slow muscle breakdown. The research just published compared one group of people in their late 60s to a group of 25-year-olds, with equal numbers of men and women. "We studied our subjects first -- before breakfast -- and then after giving them a small amount of insulin to raise the hormone to what they would be if they had eaten breakfast," Professor Rennie said. " The results were clear. The younger people's muscles were able to use insulin we gave to stop the muscle breakdown, which had increased during the night. The muscles in the older people could not. In the course of our tests, we also noticed that the blood flow in the leg was greater in the younger people than the older ones," added Professor Rennie. However, scientists think that weight training may reactivate muscle blood flow and help retain muscles for older people. "In fact, doing exercise three times a week over 20 weeks reactivates the leg blood flow responses of older people. They became identical to those in the young," said Professor Rennie. The researchers seemed to believe that _ . | [

mmlu_train_20288 | Vitamins are stored in foods we eat. The kids are udner great need of vitamins for growth. As they use their energy in playing, they need lots of vitamins. Children usually choose certain foods above the others and often do not eat those with important nutrients . Sothough the food they are eating is nutritious, it may not always provide all the nutrients the child needs. One nutrient can not balance the shortage of another. Foods like grains, vegetables, fruits and meats should be eaten daily, because different foods in the child's diet can balance against taking too much or too little of any nutrient. Kids grow slower in their childhood than when they were babies or when they develop into adults. Energy output is high, with hard paly perids that include plenty of running, jumping, and testing of new physical skills. So they need a lot of vitamins. Here are some important vitamins and their functions Vitamin D in milk helps your bones. Vitamin A in carrots helps you see at night. Vitamin C in oranges helps your body heal if you get a cut. B vitamins in leafy vegetables helps your body make protein . The children, who are suffering from a sickness called cystic fibrosis, lose vitamin A, D and E. These are main body-building vitamins. Therefore, vitamin supplements may be necessary. Blood tests will telll you whether a child needs vitamin supplements. If babies over nine months of age are receiving whole cow's milk, they'll need a daily vitamin C supplement till their diet provide enough vitamin C. Vitamin D is added to all milks so babies drinking them need no extra vitamin D. Children are greatly in need of vitamin C.

Ann said, "It's important to me because it's like my life saver." Jenny said, "I need my cellphone. I cannot live without it." So far, no studies have proven beyond question that the radio signals from cellphones cause brain cancer or other health problems. But a new study by government scientists in the United States has some people wondering what to think. The scientists have found that holding a cellphone to your ear for more than fifty minutes increases brain cell activity. Even the scientists themselves are not sure about the meaning of their findings. Dr Nora Volkow led the study. She heads the National Institute on Drug Abuse, part of the National Institutes of Health. Dr Volkow says she is not concerned that fifty minutes of cellphone exposure would harm anyone. But she says the research does show the need to study whether there are long-lasting effects of repeated exposure over several years. Her team studied forty-seven healthy volunteers between January and December of 2009. The volunteers had cellphones placed against both ears while the scientists made images of their brain activity. As part of the test, one phone was activated for fifty minutes. The other phone was off. After that, the volunteers were tested with both phones turned off. Dr Volkow says the brain scans showed increased activity in brain cells closest to the activated phone. The scans showed how the brain cells used sugar to produce energy, a normal activity. The activity was seven percent higher in areas of the brain closest to the cellphone antenna . Dr Giuseppe Esposito is a nuclear medicine expert at Georgetown University Medical Center in Washington. He says after many years of studies, better kinds of research are still needed to settle questions about cellphone safety. These studies would take years.

India's National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women. Aradhna Tripathi is a business professional in New Delhi. She said, " Eating is the most important thing in any Indian household and how you show your love and gratitude for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day. But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic . In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people. Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. _ But Doctor Misra is hopeful that the spread (,)of obesity can be slowed.

Drug and alcohol abusers struggle to give up the bad habits that hurt their bodies and destroy families and friendships. And many of us have unhealthy weight that we could lose if only we would eat right and exercise more. So why don't we do it? Some scientists have been searching for answers. They've studied what happens in our brains as habits form. They've found answers to why bad habits, once formed, are so difficult to kick. And they're developing ways to help us make the changes we'd like to make. Habits are a normal part of life, and are often helpful. " We wake up every morning, shower, comb our hair or brush our teeth without being aware of it," Volkow says. We can drive along familiar routes without really thinking about the directions. "When behaviors become automatic , it gives us an advantage, because the brain does not have to perform the action on purpose." Volkow says. This frees up our brains to focus on different things. One way to kick bad habits is to focus on your unhealthy habits. Then try your best to stop them. For example, habits can be linked in our minds to certain places and activities. You could develop a plan, say, to avoid walking down the hall where there's a candy machine. Try to avoid going places where you've usually smoked. Stay away from friends and situations linked to problem drinking or drug use. Another helpful way is to replace unhealthy habits with new, healthy ones. "It doesn't work for everyone," Volkow says. "But certain groups of patients who have a history of taking a drug can do something else like running and it helps them stay away from drugs."

mmlu_train_63338 | The human brain contains ten thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software or by altering the architecture but that two will happen. I think it is certain that in decades, not centuries, machines of silicon will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increased to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined.

Researchers from the University of Stirling's Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter.Instead, the team found that people who live in well-heated homes are more likely to have low body mass index levels while those who keep their heating turned down or off tend to be heavier. Dr Michael Daly, behavioral scientist and senior lecturer, said: "We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy. In fact, the research suggests people may eat less and burn more energy when in a warmer indoor environment. The 13-year study, published in the journal Obesity, involved more than 100,000 adults across England. Researchers found reduced weight levels among people living in homes heated to above 23degC(73F), which involved about 15,000 of the households studied. Dr Daly said: "As national gas bills continue to rise faster than the rate of inflation, this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs." This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods, exercise classes and sporting activities, and therefore finding it easier to maintain a low BMI level.The study took age, sex, social class and other factors into account. "The comfortable temperature of 20degC -23degC is where we feel comfortable in our clothes and are neither hot nor cold.At temperatures above this, we use more energy and we eat less because our appetite is affected."

mmlu_train_46964 | You want to know where the safest place for young children is in the car? For a child of any age, the back seat is the safest place and the safest part of the back seat is the middle. In the back seat, the child is farthest away from the force or effect of head-on collision , which can cause the most injuries. All fifty states of theprefix = st1 /USAhave laws requiring the use of safety seats for young children. If you have children under 8 years of age weighing no more than 80 pounds, it is necessary to fit your car with a special child safety seat. The child safety seat comes in three types or sizes: the first type is designed for babies from birth to one year of age, until the baby weighs about 20 pounds; the second size is for children between one and four years of age, who weigh between 20 and 40 pounds; the third kind is used by older children big enough to use the car's belt system. Moreover, all these safety seats must be fitted and held in place on the car's back seat. If your child does need your attention while you are driving, don't look back. Just pull over . In addition, always be sure your child is properly fastened throughout the entire trip. Children who can unfasten their own car seats are subject to fatal injuries in an accident. Start early in your child's life teaching them that car safety is serious business and make sure you give a good example and always wear your own seat belt. The third type of safety seat is for children _ . | [
