mmlu_stem | mmlu_stem_15816 | There are 45 students in our class. I have made a survey, 36 students say they like to exercise. Most boys play basketball together twice a week. But girls think basketball is difficult for them, they'd like to play volleyball together twice a week. My friend, Tony, is good at running. He runs fastest in our class. He runs for 30 minutes on the playground every evening before he goes to bed. Is it interesting? Gray is good at swimming. He goes to the swimming club three times a month in winter, and three times a week in summer. So he is pretty healthy. Some of my classmates have good eating habits. They eat both meat and vegetables. 70% of them drink milk every day. 15 students say they drink milk three or four times a week. But some students like to eat junk food, especially Sally. What's worse is that she doesn't like to exercise, so she is very fat. She always says " I'm going to lose weight tomorrow." Why do the girls dislike to play basketball? | [

mmlu_stem | mmlu_stem_5835 | What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally. Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light. The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used. Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed. Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen "fuel cells" for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars. The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth's population that has no electricity. And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night. Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by _ . With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the "world-wide hydrogen web," which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source. Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race. What is the problem with using hydrogen as energy? | [

mmlu_stem | mmlu_stem_8602 | Scientists recently found three animal species living two miles below the surface of the Mediterranean Sea, where the super-salty waters don't have oxygen . They're multicellular , which means their bodies have many cells. They each are as small as a large grain of sand. But they are animals. The most exciting thing about these creatures, say the scientists, is that they obviously don't need oxygen to live. What biologists know about life so far is that only single-celled living things can live in places that have no oxygen, and that multicellular organisms can visit these places, but not live there. These newly found creatures could _ . Finding animals down there was so surprising that the scientists couldn't believe it. At first, "we thought they were dead bodies," Roberto Danovaro, a scientist at the Polytechnic University of Marche in Ancona, Italy, told Science News. To find out whether the animals could actually live there Danovaro and his colleagues brought up more samples from the ocean floor. Studying the animals in the new samples showed that they appeared to be alive. The researchers did more tests, and found that some of the animals had eggs--which suggests they were reproducing . Also in the samples were old skins, suggesting that the animals had lived there long enough to grow. Finally, pictures taken showed that the insides of the animals appear to be adapted to live in an environment that has no oxygen. These clues suggest the animals don't need oxygen, but the evidence is indirect, which means that scientists still have not observed how the animals live without oxygen. This means more studies are needed, but the scientists think they're on the right track. And if they're right, biologists will need to rethink what they know about where animals live.

mmlu_stem | mmlu_stem_2354 | Looking back on China's road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China's first satellite into the Earth's orbit in 1970 came four flights of unmanned Shenzhou missions from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China's second human spaceflight, was launched, with a crew of two astronauts. What's more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration. Meanwhile, China's moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world's first man-made satellite, China's first circumlunar satellite Chang'e 1 took off on Oct.24, 2007, which became another milestone in China's space achievements after the above-mentioned manned flights. Chang'e 1 was expected to fulfill four scientific goals, one of which was to probe mineral elements on the moon, especially those not existent on Earth. It's said that the lunar regolith is abundant in helium-3, a clean fuel that may support the Earth's energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang'e 2, China's 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang'e 3 and Chang'e 4, as a preparation for a soft lunar landing in the future. With great expectations, people all over the world are looking forward to China's greater space achievements. According to the text, which of the following is TRUE? | [

mmlu_stem | mmlu_stem_8276 | Imagine putting a seed in a freezer, waiting 30,000 years, and then taking the seed out and planting it. Do you think a flower would grow? Amazingly, scientists have just managed to do something very similar. They found the fruit of an ancient plant that had been frozen underground in Siberia for about 31,800 years. Using pieces of the fruit, scientists successfully cloned 36 more of the plant and grew them in a lab. The new flowers have beautiful white petals . They are also the oldest flowering plants that researchers have ever revived from a deep freeze. "This is like creating a dinosaur from tissues of an ancient egg," University of California biologist Jane Shen-Miller said. The plant has a long history, back when mammoths ( an animal like an elephant, that lived a long time ago but no longer exist) wandered the land. It was buried in an underground hole. The ground has remained frozen since then. The ice-age plants look similar to a modern called Silence stenophylla. But the ancient flowers are slightly different: their petals are a bit narrower. It's possible that the regrown plants belong to a different species. It's important for scientists to know that plant tissues can still be revived after being frozen for a long time. That's because many researchers are trying to store the seeds of modern plants by freezing them and then storing them in very big lockers at various spots around the globe. The Svalbard Global Seed Vault, an underground facility in Norway, stores hundreds of thousands of seeds. If a plant becomes extinct, scientists could revive it by pulling its seeds from Svalbard or other underground rooms. Many researchers are storing the seeds of modern plants _ . | [

mmlu_stem | mmlu_stem_11547 | Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants. Sometimes, the word "green" means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today--a person who is new in a job. Someone who is good at growing plants is said to have a green thumb . The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well. Green is also the color used to describe the powerful feeling , jealousy . The green-eyed monster is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play "Othello". It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

Ray Kurzweil is the author of the successful book The Age Of Intelligent Machines. He is also one of the world's best computer research scientists. He is researching the possibilities. Kurzweil gets computers to recognize voices. An example of this is Ramona, the _ hostess of Kurzweil's website, created by the computer, who is able to understand what you say. Visitors to the website can have their own conversations with her. Ramona also dances and sings. Kurzweil uses this technology to help people with physical problems. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on around," he explains. Blind people will use a sensor which will probably be built into a pair of sunglasses. This machine will describe to the person everything it sees. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to translate what it hears into other languages, so even people without hearing problems are likely to be interested in using it. But it is not just about helping people with physical problems. Looking further into future, Kurzweil sees a time when we will be able to store what we hear, see and think in a computer. This technology probably won't be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever. What can Ramona do? | [

mmlu_stem | mmlu_stem_5168 | Butterflies are some of the most fascinating and beautiful insects in the world. Adult butterflies will live about 2 to 4 weeks. They use their senses of sight, touch, hearing, smell, and taste to survive in the world, find food and mates, lay eggs in an appropriate place, migrate, and avoid hungry enemies. Butterflies have large compound eyes , which allow them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted, so they are more attracted to a sea of flowers than individual plants. Butterflies do not "see" colors such as red, green, and yellow, but they can sense sunlight, which indicates the direction the sun is shining, as well as ultraviolet light , which is present on many flowers and guides butterflies to honey sources. Butterflies have a very well-developed sense of smell, but it is not in their nose, since they don't have one. Sense receptors are located in their antennae , feet, and many other parts of the body. They can help butterflies find their favorite flower honey food, and mates. Butterflies' feet have sense organs that can taste the sugar in flower honey, letting the butterflies know if something is good to eat or not. Some females also carefully choose host plants by tasting to find appropriate places to lay their eggs. Adult butterflies feed their babies using a long tube. Butterflies force blood into the tube to straighten it out, allowing them to feed. Butterflies get all their food from this tube. Butterflies don't have ears. Instead they "hear" sounds through their wings by sensing changes in sound vibrations . Butterflies may possess senses we don't even know about yet, because their body structure is very different from ours, and therefore difficult to understand, when observed through our own human senses. Why do female adult butterflies carefully choose the host plants? | [

The number of penguins has decreased by ( ) 30% since 1987. Penguins are black and white birds that live in the southern part of the world. They are common in the Antarctic Continent ,New Zealand, Australia and South America. Many live near cold waters . But some live near warm waters in Galapagos Islands. Penguins cannot fly, but they are fine swimmers. The shape of their body helps them to survive. Penguins eat fish and krill . They have short wings that help them to dive up to 900 feet to catch larger fish. They can swim 10-15 kilometers an hour which lets them protect themselves. They also have lots of body oil that helps in keeping them dry in the water. The warming of the earth is the reason for the decrease in the number of penguins. The hotter and hotter air has caused ocean waters to become warmer. Higher water temperature has decreased the fish and krill. Some years later these birds are completely unable toreproduce. And many adult penguins die of hunger. Too much fishing, exploration for oil and oil leaks also make penguins be in danger. Poisonous things in ocean waters are another danger.

mmlu_stem | mmlu_stem_12471 | It is reported that in the near future robots and humans will probably work together to create jazz. A singing robot is being taught to create jazz with human being in a project. Antonio Chella from Italy is working with a Telenoid robot. To start with, the Telenoid will be trained to _ the movements and simple sounds made by a human singer, and then connect music with different human emotions. Previous robots had the ability to find common connections between things. But Chella suggests that a conscious robot should be able to go a step further and find new connections. The Telenoid is of this kind. "This work raises interesting questions about the connection between consciousness and music creating." says Philippe Pasquier, a musician needs a physical body. Pasquer argues that the robot musician is faced with a big challenge. "Its software has already been developed and it can imitate The Beatles, a famous band. However, what made The Beatles famous were not only their songs but their wonderful performance of the songs," he says. It is not clear how a robot would perform music a new way. But by imitating humans, the Telenoid robot could provide some useful information.

So the Telenoid robot had better listen to more jazz music first. In Pasquier's opinion, the Telenoid robot _ | [

mmlu_stem | mmlu_stem_3764 | Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution.

Posting too much personal information for those millions of cyber eyes to see can cause some big problems and can even invite a threat to your life.

The sixth-grader put his math and science skills as well as some real-life experience to use and created something that could benefit our world a lot ---- the sandless sandbag.Today he was named the winner of the Young Scientist Challenge for his sandbag. "I had a really terrifying experience with a hurricane," said Peyton."When I was 4,I experienced Hurricane Wilma.When it hit Florida in October 2005,my family and I crowded in a closet and watched the storm bring damage and death to our area,feeling terrible and hopeless." Saltwater flooding caused great damage,which made him think about how people can prepare for floods.Peyton,who has been solving math problems since he was 3,eventually came up with the sandless sandbag. "Instead of filling it with sand,I filled it with just the right amount of chemicals and salt,"he said."What's amazing is that when you pick these bags up and they're not wet,they only weigh a pound or two." Unlike regular sandbags,Peyton's is light and easy to carry.They only expand when doused with water.The bags are portable when dry and will not float away when wet. Experts praised his invention and said that the sandless sandbag could someday save a lot of lives and possessions."He understands the big picture.He thinks in terms of the influence on society and safety for the people around this area,"said Dr.Antonio,the engineering chairman at the University of Miami."We'd love to have him at our university."

Driverless cars will not require a driver's license of any grade to operate. Anyone with basic literacy and computer skills who are at least 16 years of age will be legally allowed to operate the vehicle with absolutely no restrictions. This would give the young users permission to operate the driverless cars on major highways as well as secondary roads without needing a separate classification.

mmlu_stem | mmlu_stem_5836 | What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to? The good news is that we can. In fact, we are swimming in it--- literally. Hydrogen is one of the building blocks of the universe. Our own sun is basically a big, dense cloud of the stuff. And hydrogen can be used to create electricity for power, heat and light. The problem is that hydrogen is everywhere and nowhere at the same time. It does not exist as a material on its own, but is always part of something else. So it has to be separated before it can be used. Most commercial hydrogen in use now is created from natural gas. As oil will start to run out in around the year 2030, it makes sense to produce as much hydrogen as possible as soon as we can. But natural gas supplies will also begin to run out soon after. Another source is needed. Researchers are now using electricity to make water into hydrogen. Companies are working on the problem in their own areas. The first commercial hydrogen "fuel cells" for computers and mobile phones have already come on to the market. Auto companies have also invested over US $2 billion in the production of hydrogen fuelled cars. The nations of a hydrogen fuelled planet would not fight over energy recourses. There would be a great reduction in pollution. The only by-product of creating hydrogen is pure drinking water--- something that is very scarce in many parts of the world. But that is not where the good news ends. Once the costs of producing hydrogen have been brought down, it will possibly provide power for a third of the Earth's population that has no electricity. And electricity creates wealth. In South Africa over the last decade there has been a large programme of electrification. Thanks to the programme, people do not have to spend their days looking firewood to burn for heat. And with electric light, they can work long into the night. Some scientists see radical changes in the way the human race co-operates. Hydrogen creates electricity, and is also created by _ . With dual use fuel cells, everyone who consumes energy could also produce it. Late at night, a man drives home in London and connects his car into the "world-wide hydrogen web," which it supplies with electricity. A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car. Hydrogen could be the first democratic energy source. Like all dreams of the future, it seems very far away. But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to end oil dependency and spend more time and money on hydrogen resource. So maybe the threat of war is not a completely bad thing for the future of the human race. What is the passage mainly about? | [

mmlu_stem | mmlu_stem_10801 | BEIJING, Sept. 29 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced Thursday night that the launch of Tiangong-1 space lab module is successful. China's first space lab module Tiangong-1 blasted off at 9:16 p.m. Beijing Time (1316 GMT) Thursday from Jiuquan Satellite Launch Center in northwest desert area. The unmanned module, carried by Long March-2FT1 rocket, will test space docking with a spacecraft later this year, _ the way for China to become the third country in the world to operate a permanent space station around 2020. The Tiangong-1 will orbit the Earth for about one month to await Shenzhou-8 unmanned spacecraft. Once the two vehicles successfully rendezvous , they will conduct the first space docking at a height of 340 kilometers above Earth surface. After two docking tests, Tiangong-1 will await Shenzhou-9 and Shenzhou-10 in the next two years, according to a plan of China's manned space program. The 8.5-tonne Tiangong-1, with a length of 10.4 meters and maximum diameter of 3.35 meters, provides a room of 15 cubic meters for two to three astronauts to live and work. Zhang Shancong, deputy chief designer of the Tiangong-1, told Xinhua that the module carries special cameras which will take hyperspectral images of China's vast farmlands to detect heavy metal pollution and pesticide residue as well as plant disease. Moreover, scientists on the ground will also conduct experiments on photonic crystal , a new material expected to revolutionize information technology, in the low-gravity environment inside the Tiangong-1 as these experiments would be extremely difficult to conduct on Earth's surface. "China is clearly becoming a global power and its investments in areas like technology and space exploration reflect this," said Peter Singer, a senior fellow at the Washington-based Brookings Institution. "It is a natural result of the growth in political and economic power and is to be expected," said Zhou Jianping, chief designer of China's manned space program, "China will turn its future space station into an international platform for space research and application. A space station could provide a low-gravity environment for research on geography, astronomy and bio-technology, which will bring unimaginably greater achievements than those conducted on Earth's surface. " "The Chinese nation has pursued peace since ancient times," Zhou also said, "China's ultimate intention with the space program is to explore space resources and make use of them for mankind's well-being."

Citing secret documents provided by Edward Snowden, former NSA staff, the reports detail efforts to gain data collection from cell phone carriers and smart phones by tapping into "leaky" apps themselves. Both spy agencies showed a particular interest in Google Maps, which is accurate to within a few yards or better in some locations and would clearly pass along data about the area where phone owner is. "It effectively means that anyone using Google Maps on a smartphone is working in support of a GCHQ system," reads a secret 2008 report by the NSA's sister spy agency, according to the New York Times. More surprising is the wide range of apps that the agencies search for data, including innocent-seeming apps such as Angry Birds. One document in particular from GCHQ listed what information can be found from which apps, mentioning Android apps but suggesting the same data was available from the iPhone platform. Angry Birds maker Rovio Entertainment of Finland said it had no knowledge of any NSA or GCHQ programs for tapping into its users' data. "Rovio doesn't have any previous knowledge of this matter, and have not been aware of such activity in 3rd party advertising networks," said Saara Bergstrom. "Nor do we have any involvement with the organizations you mentioned." Mobile photos uploaded to social media sites like Facebook and Twitter appear to be a particularly rich source of information for the spy agencies as well. Metadata in the photos is briefly available. The NSA and GCHQ are able to tap into that metadata to collect a wealth of key data points about a person's life.

"I've even passed by my son and daughter without recognizing them." He is not the only one. Those with prosopagnosia, also known as face blindness, can see perfectly well, but their brains are unable to piece together the information needed to understand that a collection of features represents an individual's face. The condition is a neurological mystery, but new research has shed light on this strange disease. Some scientists had believed that faces and voices, the two main ways people recognize one another, were processed separately by the brain. Indeed, a condition parallel to prosopagnosia, called _ , similarly leaves a person unable to distinguish a familiar voice from an unfamiliar one. But by testing for these two conditions at the same time, researchers at the Max Planck Institute recently found evidence that face and voice recognition may be linked in a unique person-recognition system. The scientists observed the brain activity of 19 healthy volunteers as they were led through tasks that tested their ability to recognize both faces and voices. The researchers found that regions of the brain, associated with facial recognition, are directly linked to regions responsible for voice recognition. This research helps explain why a person with prosopagnosia may still have difficulty determining who a person is even after he has begun to speak. The challenge for scientists is to find out where this system breaks down. Are these connections in the brain missing entirely, or are people unable to recognize faces and voices simply unable to use these links in some way?

mmlu_stem | mmlu_stem_10170 | Two more people have died in China from a new strain of bird flu, raising the death toll from the virus to 13, state media reported Sunday. The official Xinhua News Agency said the two deaths were reported in Shanghai and that three new cases were also confirmed in the financial hub. A total of 11 new cases were reported Sunday - including two in a central province that previously had been unaffected. In all, 60 cases of the virus, known as H7N9, have been reported in China. The two cases reported Sunday in central Henan province, which is next to Beijing, followed an announcement Saturday that a 7-year-old girl had become the first person in the capital to be infected with the virus. All previous reported cases were in Shanghai and other eastern areas of China. A World Health Organization official said Sunday that it wasn't surprising that the virus had spread to Beijing. Michael O'Leary, head of WHO's office in China, said it's not the case that everyone confirmed to be infected with H7N9 was "clustered in one small area with the same source of exposure." "So we've been expecting new cases to occur. ... Furthermore, we still expect that there will be other cases," he said. Four new cases were reported Sunday in eastern Zhejiang province and two more in Jiangsu. Health officials believe the virus, which was first spotted in humans last month, is spreading through direct contact with infected fowl. O'Leary said "the good news" was that there was still no evidence that humans had passed on the virus to other humans. "As far as we know, all the cases are individually infected in a sporadic and not connected way," he said, adding that the source of infection was still being investigated. The girl from Beijing, whose parents are in the live poultry trade, was admitted to a hospital Thursday with symptoms of fever, sore throat, coughing and headache, the Beijing Health Bureau said. O'Leary said early treatment can be effective, as demonstrated by the girl, who was in stable condition. In the only other reported cases outside of eastern China, health officials in Henan province said tests on two men Thursday had later revealed they had the virus. They said a 34-year-old restaurant chef who had displayed flu symptoms for about a week was in critical condition in a hospital, while a 65-year-old farmer who was in frequent contact with poultry was in stable condition after receiving treatment. They said 19 people who had been in close contact with the two men did not show any flu symptoms.

mmlu_stem | mmlu_stem_5797 | For centuries, medical pioneers have refined a variety of methods and medicines to treat sickness, injury, and disability, enabling people to live longer and healthier lives. "A salamander (a small lizard-like animal) can grow back its leg. Why can't a human do the same?" asked Peruvian-born surgeon Dr. Anthony Atala in a recent interview. The question, a reference to work aiming to grow new limbs for wounded soldiers, captures the inventive spirit of regenerative medicine. This innovative field seeks to provide patients with replacement body parts. These parts are not made of steel; they are the real things --- living cells, tissue, and even organs. Regenerative medicine is still mostly experimental, with clinical applications limited to procedures such as growing sheets of skin on burns and wounds. One of its most significant advances took place in 1999,when a research group at North Carolina's Wake Forest Institute for Regenerative Medicine conducted a successful organ replacement with a laboratory-grown bladder. Since then, the team, led by Dr. Atala, has continued to generate a variety of other tissues and organs from kidneys to ears. The field of regenerative medicine builds on work conducted in the early twentieth century with the first successful transplants of donated human soft tissue and bone. However, donor organs are not always the best option. First of all, they are in short supply, and many people die while waiting for an available organ; in the United States alone, more than 100,000 people are waiting for organ transplants. Secondly, a patient's body may ultimately reject the transplanted donor organ. An advantage of regenerative medicine is that the tissues are grown from a patient's own cells and will not be rejected by the body's immune system. Today, several labs are working to create bioartificial body parts. Scientists at Columbia and Yale Universities have grown a jawbone and a lung. At the University of Minnesota, Doris Taylor has created a beating bioartificial rat heart.

Besides the earth, the "red planet" is seen, as the one place in our solar system most likely to have life. Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines' safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet. But the trips made by Spirit and Opportunity were dangerous. Mars is often called the "death planet", because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them.

mmlu_stem | mmlu_stem_11059 | In an ideal world,people would not test medicines on animals. Such experiments are stressful and sometimes painful for animals,and expensive and timeconsuming for people. Yet animal experimentation is still needed to help bridge vast gaps in medical knowledge. That is why there are some 50 to 100 million animals used in research around the world each year. Europe,on the whole,has the world's most restrictive laws on animal experiments. Even so,its scientists use some 12 million animals a year,most of them mice and rats,for medical research. Official statistics show that just 1.1 million animals are used in research in America each year. But that is misleading. The American authorities do not think mice and rats are worth counting and,as these are the most common laboratory animals,the true figure is much higher. Japan and China have even less comprehensive data than America. Now Europe is reforming the rules governing animal experiments by restricting the number of animals used in labs. Alternatives to animal testing,such as using human tissue or computer models,are now strongly recommended. In addition,sharing all research results freely should help to reduce the number of animals for scientific use. At present,scientists often share only the results of successful experiments. If their findings do not fit the hypothesis being tested,the work never sees the light of day. This practice means wasting time,money,and animals' lives in endlessly repeating the failed experiments. Animal experimentation has taught humanity a great deal and saved countless lives. It needs to continue,even if that means animals sometimes suffer. Europe's new measures should eventually both reduce the number of animals used in experiments and improve the way in which scientific research is conducted.

mmlu_stem | mmlu_stem_4811 | Four hundred years ago, an Italian scientist named Galileo Galilei became the first person to see the craters on the moon. Galileo was one of the first people to use a telescope to study the sky. Since then, telescopes have become the most important tool used by astronomers. Scientists never stop finding new ways to make these instruments more powerful. In the next several years, two new telescopes with different purposes are to be used. One of the telescopes, called Pan-STARRS, could save humans from dying out. Nick Kaiser, a scientist who works on the project, says the Pan-STARRS telescope has been designed to find "90 percent of all killer asteroids near Earth". Pan-STARRS, like most telescopes, uses mirrors and lenses to provide pictures of outer space. Giant mirrors are used to "gather" light. They reflect the light onto the lens of a camera, which can then record the image. When completed, Pan-STARRS will include four telescopes which will be put on top of a mountain on the Hawaiian island of Maui. Only one telescope is in place and working now. Each telescope will take pictures of one patch of sky for about 30 seconds, and then move on to another patch. Every night, each telescope will take pictures of about 1,000 patches. Every week, each telescope will have photographed the whole sky. Each of the four telescopes will take pictures of the same patches of sky. One telescope, working alone, may sometimes incorrectly show an asteroid. If there are three other telescopes working, astronomers can use them to see if there really is an asteroid coming our way. By using four telescopes instead of one, scientists hope to get a better picture of space. If a giant asteroid was identified, astronomers would try to break it up long before it reached Earth.

Goats have more uses than you could ever imagine. Goat's meat can be eaten and goat's milk is becoming popular as a healthy choice to drink milk. Goat's milk is easier to take in than cow's milk and it is called universal milk as it can be used to bottle-feed most animals. In nutrition, it is also good. Goat's skins are still used today to make gloves and other items of clothing. The initial reasons for domesticating goats were to get goat's hair, meat and milk. Goat's skins were used up until the Middle Ages for making bottles to hold water and wine for people who were traveling or camping. Just like sheep, goats are considered to be the first domesticated animal. The domestication process began over 10,000 years ago in a North Iranian town. A lot of people keep goats as pets nowadays. Goats are easily trained and you can teach them to pull carts and walk on ropes. Goats are also known for escaping their pens . If you have unsecured fencing, your goats will be interested in it and test it out and soon you will know where the openings are. Goats are also widely known for their ability to climb trees, although the tree generally has to be at a slight angle .

mmlu_stem | mmlu_stem_8902 | As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, "Freddie, Freddie." _ My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize him, I couldn't believe what was happening. When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery , and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn't go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, "What if we get there and he's dead?" "Is he going to be brain-damaged?" Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child--he was covered in tubes and there were wires coming out of his head. On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie's brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn't say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself. I still don't know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below. The guilt I feel is awful-- for weeks I was full of " if onlys", and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me.

mmlu_stem | mmlu_stem_10261 | An extinct mountain goat that was once common in the Pyrenees became the first animal to be brought back from extinction. Researchers used frozen DNA to produce a clone, but the newborn kid died within minutes of birth due to breathing difficulties. The Pyrenean ibex is a type of mountain goat,which is believed to have died out completely in 2000. Before the death of the last known individual(a13-year-old female known as Celia), biologists took cells from her skin and ears. An earlier cloning attempt to use the skin cells failed. But the latest attempt involved the creation of 439 cloned embryos. Of these cloned embryos, 57 were put into the female domestic goats, but only one goat gave birth and the newborn cloned kid died after seven minutes as a result of lung disease. Researchers say that other cloned animals, including sheep, have been born with similar lung disease, but they say that overall the experiment was a major step forward in the effort to bring the ibex back to its mountain home. The leading researcher Jose Folch says, "the cloned kid was genetically like the ibex;in species such as the ibex,cloning is the only possibility to avoid its complete disappearance." The failure to produce a living clone from DNA that was frozen only a decade ago shows the difficulty researchers would face in trying to bring back species that have been extinct for decades or centuries. Researchers have had the idea of bringing back the Tasmanian tiger, which went extinct in 1936. There are, however, other species that have been seriously suggested for cloning,such as the giant panda, the African bongo antelope, the Sumatran tiger and the pygmy hippo. Supporters believe cloning provides hope of keeping these endangered animals alive before they die out. What's the best title for this passage? | [

mmlu_stem | mmlu_stem_3212 | Japanese doctors have used thin sheets of tissue from people's cheeks repair damaged corneas . A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition,reports BBC online. Patients whose vision had been cloudy could see well afterwards,and the"new corneas"remained clear more than a year after the operation. Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea,or they can transplant corneas from donors . But these techniques may not work when both eyes are too badly damaged by accident or disease. The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants. The cornea is the clear layer of cells on the surface of the eye. It can be damaged by trauma or by a range of diseases. The team worked with four patients who had a painful condition that causes cloudy corneas and dry eyes. Often the eye can regenerate cornea cells but none of the four patients had this ability. The researchers took a 3 mm-wide square of tissue from inside the mouth(cheeks)and grew it into a thin layer in the lab. They used a special low temperature technique to separate a very thin sheet off each batch. They then laid that onto the patient's eye. The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea. However,long-term follow-up and experience with a large series of patients is needed to assess the benefits and risks this method. Yet,"it does offer the potential of treating severe eye diseases that are resistant to standard approaches,"said the head of the research,Kohji Nishida.

In fact, you probably felt quite defeated when you first tried to do any serious climbing. Indoor and outdoor rock climbing are both extremely demanding and require practice to get good at. It is one of the most physically and mentally demanding sports. There are three basic types of rock climbing. Top roping is the most common type and the climber need to climb with a partner. The second type, which is very similar to top roping, is called lead climbing. In both of the types, the climber can sit off the wall and rest on the rope. The third type is called bouldering. Bouldering is a type of free climbing without any ropes. This is the most demanding of all climbing types. The climber must be able to complete the climbing without taking a rest on the rope. Believe it or not, climbing is said to be about 75% legs and only 25% arms. To climb efficiently and successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to always have three points touching the wall, whether it is both feet and one hand, or one foot and both hands, as it is much easier to have your weight cases will not do the climbing; they only hold you into the wall so that your legs are actually pushing you upward. Also, the closer you are to the wall, the easier it is to climb. Rock climbing may sound a bit too extreme for the everyday person, but it is really an amazing workout. Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems. The great thing about rock climbing is that it is mentally challenging as well. You are constantly analyzing the way your body moves and how to do certain moves on the wall.

Their advice is part of a review aimed at doctors who deal with dog bites. "Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some time, boys more than girls. Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have made news headlines. Based on the latest medical evidence, _ advise doctors how to examine and treat a patient presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For travelers bitten abroad, they suggest assessing the risk of rabies . In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies. "Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime dog owner, in an article. "It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog", she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational programs are also needed to teach children about some precautionary behaviors around dogs. Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors promoting bite prevention when treating patients who have been bitten by dogs.

mmlu_stem | mmlu_stem_11724 | Elephants have four distinct personalities that help their herd survive in the African bush, scientists have found. With their grey skin, mournful eyes and slow heavy pace, you could be forgiven for thinking elephants are uniformly melancholy creatures. But scientists have now discovered the largest living land animals have personalities to match their size. In a new study of African elephants, researchers have identified four distinct characters that are common in a herd - the leaders, the gentle giants, the playful rogues and the reliable plodders . Each of the types has developed to help the giant mammals survive in their harsh environment and is almost unique in the animal kingdom, according to the scientists. Professor Phyllis Lee and her colleague Cynthia Moss studied a herd of elephants in the Amboseli National Park in Kenya known as the EB family -- famous for their matriarch Echo before she died in 2009. Using data collected over 38 years of watching this group, the researchers analyzed them for 26 types of behavior and found four personality features tended to emerge. The strongest personality to emerge was that of the leader. Unlike other animals, where leadership tends to be won by the most dominant and aggressive individual, the elephants instead respected intelligence and problem solving in their leader. Echo, the matriarch and oldest in the group, her daughter Enid, and Ella, the second oldest female, all emerged as leaders. The playful elephants tended to be younger but were more curious and active. Eudora, a 40-year-old female in the herd, seemed to be the most playful, consistently showing this feature throughout her life while playfulness in some of the other elephants declined with age. Gentle elephants, which included two 27-year-old females Eleanor and Eliot, touched and rubbed against others more than the others. Those that were reliable tended to be those that were most consistent at making good decisions, helped to care for infants in the herd and were calm when faced with threats. Echo and her youngest daughter Ebony seemed to be the most reliable. Professor Lee said that elephants with these features tended to be the most socially integrated in the group while those who tended to be less reliable and pushy were more likely to split from the herd. From the passage we get to know that _ . | [

mmlu_stem | mmlu_stem_5805 | "I see you've got a bit of water on your coat," said the man at the petrol station. "Is it raining out there?""No, it's pretty nice," I replied, checking my sleeve. "Oh, right. A pony bit me earlier." As it happened, the bite was virtually painless: more the kind of small bite you might get from a naughty child. The pony responsible was queuing up for some ice cream in the car park near Haytor, and perhaps thought I'd jumped in ahead of him. The reason why the ponies here are naughty is that Haytor is a tourist-heavy area and tourists are constantly feeding the ponies foods, despite sighs asking them not to. By feeding the ponies, tourists increase the risk of them getting hit by a car, and make them harder to gather during the area's annual pony drift . The purpose of a pony drift is to gather them up so their health can be checked, the baby ones can be stooped from feeding on their mother's milk, and those who've gone beyond their limited area can be returned to their correct area. Some of them are also later sold, in order to limit the number of ponies according to the rules set by Natural England. Three weeks ago, I witnessed a small near-disaster a few mils west of here. While walking, I noticed a pony roll over on his back. "Hello!" I said to him, assuming he was just rolling for fun, but he was very still and, as I got closer, I saw him kicking his legs in the air and breathing heavily. I began to properly worry about him. Fortunately, I managed to get in touch with a Dartmoor's Livestock Protection officer and send her a photo. The officer immediately sent a local farmer out to check on the pony. The pony had actually been trapped between two rocks. The farmer freed him, and he began to run happily around again. Dartmoor has 1,000 or so ponies, who play a critical role in creating the diversity of species in this area. Many people are working hard to preserve these ponies, and trying to come up with plans to find a sustainable future for one of Dartmoor's most financially-troubled elements.

mmlu_stem | mmlu_stem_9297 | Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday. They found that when people listened to their favorite music, their blood vessels _ in much the same way as when they are laughing, or taking blood medications. "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology at the University of Maryland Medical Center in Baltimore. "Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins. When blood vessels open up more, blood flows more smoothly and is less likely to form the clots that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans. Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function. Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked -- in most cases in this group heavy metal -- blood vessels narrowed by six percent, Miller said. Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said. Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual. What is the passage possibly taken out from? | [

mmlu_stem | mmlu_stem_1629 | Once upon a time there was a boy monster named Jerry who lived in a train car at the railroad tracks. He had lived there all his life. Jerry's mother was named Marge, and she was 36. Marge raised Jerry at the railroad tracks because she wanted to keep him safe. She was afraid of the people who lived in the town nearby. The town was named Qarth, and 100 people lived there. Marge believed that the people of Qarth would attack them if they knew they were there. Qarth used to be filled with factories when Jerry was born. By the time Jerry was a teenager, most of the factories had gone away and most of the people worked on special new machines. They ate food from the fields outside of town. Their favorite food to eat was a special kind of corn. They didn't eat meat because nobody raised any farm animals. One day when he was 11, Jerry asked his mother who his father had been. His father's name was George, and he was 2 years older than Marge. Marge looked sad and told Jerry that George had left after he was born because the people in the town didn't like him. This made Jerry very sad. He went off to his corner of the car and didn't talk to Marge again until she went to bed. After she fell asleep he wanted to go out and look for his father. He packed some food and left. When Marge woke up she was upset, but she thought she knew where he had gone. How old was Jerry when he asked his mother who his father had been? | [

mmlu_stem | mmlu_stem_12762 | Do you know why people look the way they look? What inside our bodies makes us grow in a certain way? The answer is DNA. It was first discovered by a young Swiss doctor in 1868. DNA is like a computer program for your body. Almost every cell in your body includes DNA. The way DNA in the cell decides why you are the way you are. For example your friend might have larger ears than you. This is because their DNA is different from yours. DNA lives in the cell and is ordered in a structure called a "double helix ". In each double helix there are links called as chromosomes . These chromosomes are made from four bases that arrange themselves in millions of different ways. The way these bases choose to line up is what makes the DNA code for that cell. DNA is also called a "gene ". This is a very interesting thing. Genes are passed down from your parents. That is why you might have the same smile like your dad's or mom's! In February, scientists found the skeleton of Richard III, King of England from 1483-1485, under a car park in England. It seems unlikely that scientists could identify a 527-year-old skeleton. However, they matched the skeleton's DNA to a sample from one of his direct descendants . How amazing! _ discovered DNA. | [

mmlu_stem | mmlu_stem_7347 | Where do dogs come from? Gray wolves are their ancestors. Scientists are pretty consistent about that. And researchers have suggested that dogs' origins can date back to Europe, the Near East, Siberia and South China. Central Asia is the newest and best candidate, according to a large study of dogs from around the world. Laura M. Shannon and Adam R. Boyko at Cornell University, and an international group of other scientists, studied not only purebred dogs, but also street or village dogs. Dr. Shannon analyzed three different kinds of DNA, Dr. Boyko said, the first time this has been done for such a large and diverse group of dogs from 38 countries. And that led them to Central Asia as the place of origin for dogs in much the same way that genetic studies have located the origin of modern humans in East Africa. The analysis, Dr. Boyko said, pointed to Central Asia, as the place where "all the dogs alive today" come from. The data did not allow precise dating of the origin, he said, but showed it occurred at least 15,000 years ago. Greger Larson of Oxford University, who is leading a large international effort to analyze ancient DNA from fossilized bones, said he was impressed by the study. "It's really great to see not just the number of street dogs, but also the geographic breadth and the number of remote locations where the dogs were sampled," he said in an email. He also praised the sampling of different kinds of DNA and the analytic methods. Dr. Larson, who was not involved with the study, said he thought the Central Asia finding required further testing. He said he suspected that the origins of modern dogs were "extremely messy" and that no amount of sampling of living populations will be definitive. He said a combination of studies of modern and ancient DNA is necessary. Greger Larson got a very deep impression of his study because he _ . | [

mmlu_stem | mmlu_stem_12682 | Spring is an inviting season for outdoor activities. But be careful--the warm weather is also a hotbed for viruses and disease. This March, the influenza A(H7N9) virus hit Shanghai, Anhui, Jiangsu and Zhejiang. It was reported that by April 11 at least 35 people had been infected with the H7N9 virus, and nine of them had died. The influenza A (H7N9) virus is one type of influenza A H7 viruses. Influenza A H7 viruses normally spread among birds. This is the first time human infections with H7N9 viruses have been reported in China. Earlier reports were about H5N1 and H1N1. All the three viruses are influenza A viruses but they are not the same. H7N9 and H5N1 are animal influenza viruses that could infect people. However, H1N1 viruses can be divided into two groups. One group can normally infect people and the other normally infects animals. Also, H1N1 can spread from human to human, but H7N9 probably can't, according to the World Health Organization (WHO). Most people infected with H7N9 looked like they had the common flu. Some people had bad pneumonia . They suffered from a fever, a cough and shortness of breath. But don't be afraid - it is not easy to be infected with the virus. One of the possible reasons is close contact with sick poultry waste. People may also be infected through breath, according to National Health and Family Planning Commission. Here are some tips from the WHO that can protect you from being infected. Wash your hands with soap and running water before you eat, after you use the toilet, and after touching animals or animal waste. When coughing or sneezing cover your mouth and nose with a mask ,tissue or a sleeve. Get a good rest and do exercises, which will help make your body strong enough to stand up to the virus.

Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since. The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago. Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology. "We have come to the conclusion, based on last week's satellite landing," Prof. Zog said, "that there is no life on Earth." "How do you know this?" the science reporter of the Venus Evening Star asked. "For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide and other deadly gases and nobody could possibly breathe this air and survive." "What does this mean as far as our flying saucer program is concerned?" "We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned." "Are there any other dangers that you discovered in your studies?" "Take a look at this photo. You see this dark black cloud hovering over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there." "Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer." "If all you say is true, won't this set back the flying saucer program several years?"

mmlu_stem | mmlu_stem_5621 | Using tablet computers like Apple's iPad and Samsung's Galaxy Note just before bed can lead to a poor night's sleep, according to research. More and more people are taking their tablets to bed with them to surf the web, check Facebook or email before switching off the light. But researchers are warning that the blueish light their screens emit can stop users getting a good night's sleep. That is because this type of light mimics daylight, convincing the brain that it is still daytime. Blue light suppresses production of a brain chemical called melatonin, which helps us fall sleep. This is because our brains have evolved to be wakeful during daylight hours. By contrast, light which is more orange or red in tone does not reduce melatonin production, perhaps because our brains recognize it as a cue that the day is ending. Neurologists have known for years that staring at screens late in the evening can disrupt sleep. Researchers at the Lighting Research Centre, at the Rensselaer Polytechnic Institute in New York, are warning that looking at tablet displays for more than two hours "leads to a suppression of our natural melatonin levels as the devices emit optical radiation at short wavelengths" - in other words, they emit bluer light. They say: "Although turning off devices at night is the ultimate solution, it is recommended that if these devices are used at night displays are dimmed as much as possible and that the time spent on them before bed should be limited." They drew their conclusions after measuring melatonin levels in 13 volunteers, after they had spent time viewing iPads at full brightness at a distance of 10 inches, for two hours. Melatonin levels were significantly lower after they had done this, than they were after the volunteers had viewed their iPads for the same time, but while wearing orange glass goggles, which cut out the blue light. They wrote in the journal Applied Ergonomics that tablet makers could "tune the spectral power distribution of self-luminous devices " so that they disrupted the sleep patterns of users less. It is not just a good night's sleep that could be jeopardized by too much late night screen time. Researchers know that persistent disruption to sleep patterns can lead to an increased risk of obesity, and even breast cancer. However, these studies tend to be comparisons of those with chronic sleep disruption, such as long term shift workers, with those who have normal sleep patterns. We can infer from the passage that _ . | [

To experience it,you'll need special pieces of software called plug-ins.The term "plug-in" refers to a small,add-on piece of software which extends the capabilities of your web browser,like Netscape Navigator or Microsoft Explorer,turning your computer into a radio or TV. When you arrive at a web page which contains a file requiring a plug-in which you don't have,you will usually receive a message asking if you want to get it by downloading it and installing it into your computer.Most of the time,the installation will be automatic. Occasionally,you'll run into a downloaded file which needs to be decompressed or un-zipped before installation.Once installed,plug-ins run automatically,without you having to do anything. Many multimedia controls still need to be obtained from the developer but are installed automatically. Shockwave is a good example of this.All you need to do is go to the Macromedia site and click on the link to install the ActiveX control.The rest happens automatically.The next time you go to a "Shocked" website,the Shockwave control loads and plays the movie.
