mmlu_stem | mmlu_stem_10206 | An astronomer is making a case for launching pop singer Justin Bieber into suborbital space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager -- he would come back down to Earth eventually, after all -- but rather to help jump-start the emerging suborbital spaceflight industry. It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. "If there's more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good." Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport. None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z. Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists -- but Shostak is thinking about ways to make it grow. A celebrity launch isn't Shostak's only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling with cameras both inside and out, to give the public dramatic views of every mission. Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry's success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space. Why may Justin Bieber be sent into suborbital space? | [

mmlu_stem | mmlu_stem_6247 | A meteorite flew fast across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, damaged buildings and injured l,200 people. People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave. According to Russian space agency Roscosmos, the fireball, travelling at a speed of 30km per second, had burnt very brightly across the horizon, leaving a long white trail that could be seen as far as 200km away. Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted. "I was driving to work, it was quite dark, but it suddenly became as bright as if it were day," said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. "I felt like I was blinded by headlights." The meteorite, which weighed about 20 tons and may have been made of iron, entered Earth's atmosphere and broke apart 30-50km above ground, according to Russia's Academy of Sciences. The energy released when it entered the Earth's atmosphere was about several thousand tons, the academy said, the power of a small atomic weapon exploding. No deaths were reported, but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims. The Interior Ministry said about l,200 people had been injured, at least 200 of them children, and most from broken pieces of glass."While events this big are rare, an impact that could cause damage and death could happen every century or so.

mmlu_stem | mmlu_stem_183 | A Natural Snake-Bite Antidote? Snake bites and bee stings can be either painful or downright deadly, depending on which species is doing the biting, and sometimes whether the person being bitten is allergic to the venom. New research in mice suggests that these bites and stings would be even more dangerous if not for a special defensive trick that the mouse's immune system can pull off. Dr. Stephen Galli of Stanford University and his colleagues studied mast cells, which are immune cells that contribute to the inflammation that's part of asthma, allergies and even the extreme, anaphylactic shock that can happen to some people with severe allergies to things like peanuts. In these cases, the immune system gets mixed up and thinks it's being attacked by something harmful. But, mast cells also do beneficial things in the body. The scientists discovered that the cells also play a helpful role against certain snake and honeybee venoms. In their study they showed that the cells protected mice, making the venom's effects less harmful. The cells released an enzyme that broke down dangerous components of the venom of a snake called the Israeli mole viper. Dr. Galli said that it might someday be possible to make better snake bite or bee sting treatments that are based on this type of enzyme. More research will be necessary to see if this is possible. Dr. Galli thinks that this feature of the mast-cell defense system may have evolved, in animals that are prey to snakes or get stung by bees, partly as a way to help to protect against venom. This defense isn't foolproof or perfect, but it gives the prey animals a better chance of survival, especially if they get less than a "full dose" of venom in the bite of a poisonous snake.

He passes me a hot cup of coffee. "Not long to wait now," he says. I hope he's right. After a few minutes there is a very weak light in the east, and then I hear a bird singing. It sings very loud and very clear. "That's the robin ," says Jim. A few more birds start singing with the robin and Jim knows the names of them too. Half an hour later, there are more and more birds singing, and it's very loud! Suddenly, all around us the air is full of the sound of birdsong. This is the dawn chorus , and it's beautiful. "Wow, this is amazing!" I tell Jim, who is smiling. "Is there a dawn chorus every morning?" "Birds can sing any time of the year but the best time is the end of winter and during the spring. This is when the birds sing most." "Really? So, why do they sing?" I ask. "Well, there are two reasons," explains Jim. "Most of the songbirds who sing are males. They want to find a female so they sing to show how strong they are. The females listen and choose the best singer! The birds also sing to tell other males to go away. They need their own area; they don't like sharing with another male." I listen to the birds; the songs seem too much to me. "Do the birds sing a special song in the morning?" "That's a good question," replied Jim. "The successful birds have many kinds of calls and songs. Sometimes they copy the songs of other birds. This makes it sound like there are many birds in that place already and other males stay away. Also the female likes songs with different notes. Some birds, for example the European wren, have songs that contain over 700 different notes per minute!" So, how does Jim know so much about birds? Well, he works as a volunteer for the Royal Society for the Protection of Birds. He is trying to help the birds live in the modern world. "More and more of the birds' habitat disappears every year. The sparrow, for example, was a very common bird in the UK, now it's in danger." By now the sun is up and the birds are quiet.

But recently, some people have been much more worried about how the grizzly bear and mountain lion can cross the road. "Millions of animals die each year on U.S. roads," the Federal Highway Administration reports. In fact, only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill. "Eco-passages" may help animals cross the road without being hit by cars. They are paths both over and under roads. "These eco-passages can be extremely useful, so that wildlife can avoid road accidents," said Jodi Hilty of the Wildlife Protection Society. But do animals actually use the eco-passages? The answer is yes. Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway. This showed that the lions used the passage. Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them. Animals seem to be catching on.

mmlu_stem | mmlu_stem_11932 | Wind turbines are efficient sources of cheap energy but also a source of concern as their huge spinning blades frequently kill birds and bats. A new type of wind generator developed in Spain offers a creative solution to that problem. In 2002, Spanish inventor David Yanez saw a short film about the Tacoma Narrows Bridge in the U.S., collapsing in strong wind. It was a vivid example of the powerful vibrations wind can create when it blows past a long pole, such as a car antenna or even a stick of bamboo. It gave him the idea for a new type of wind-energy generator. "The initial philosophy or spirit was to create a generator of dreams that had all the qualities one would want: It should be as cheap as possible, need as little maintenance as possible, the setup as simple as possible," he said. Yanez and his friend Raoul Martin took the idea to an engineering firm, where they were told it would never work. Undiscouraged, they started experimenting on their own in a small wind tunnel they built. Good initial results were repeated by a larger working model called Vortex installed in a nearby field. "What we have is a mast , which is the top piece and acts as a blade," Yanez said. "It's constructed from the same material as a conventional generator, and what it does is it oscillates , transmitting the oscillation to a conventional alternator, which by its own oscillation converts the wind's energy into electric energy." Yanez said the output of the 6-meter-tall generator, and even that of smaller models, was better than expected. The Vortex creates about 30 percent less energy than a comparable bladed wind turbine, but it is lighter and cheaper to build and maintain. It is made mostly of reinforced plastic and has very few moving parts. Also, it does not create noise and--even more important for many environmentalists--it does not present a threat to passing birds. The current prototype works at wind speeds ranging from 1.5 to 7 meters per second. The inventors say the next step is building a 12.5-meter tall bladeless generator with a 4-kilowatt capacity that could power small businesses or individual homes, or provide supplemental power to a main grid. The commercial version of the Vortex Bladeless generator should be ready for the market by 2017. What would be the best title for the passage? | [

mmlu_stem | mmlu_stem_5421 | Knots are the kind of stuff that even myths are made of.In the Greek legend of the Gordian knot, for example, Alexander the Great used his sword to slice through a knot that had failed all previous attempts to unite it. Knots, enjoy a long history of tales and fanciful names such as "Englishman's tie, " "and "cat's paw. " Knots became the subject of serious scientific investigation when in the 1860s the English physicist William Thomson (known today as Lord Kelvin) proposed that atoms were in fact knotted tubes of ether . In order to be able to develop the equivalent of a periodic table of the elements, Thomson had to be able to classify knots -- find out which different knots were possible. This sparked a great interest in the mathematical theory of knots. A mathematical knot looks very much like a familiar knot in a string, only with the string's ends joined. In Thomson's theory, knots could, in principle at least, model atoms of increasing complexity, such as the hydrogen, carbon, and oxygen atoms, respectively. For knots to be truly useful in a mathematical theory, however, mathematicians searched for some precise way of proving that what appeared to be different knots were really different -- the couldn't be transformed one into the other by some simple manipulation . Towards the end of the nineteenth century, the Scottish mathematician Peter Guthrie Tait and the University of Nebraska professor Charles Newton Little published complete tables of knots with up to ten crossings. Unfortunately, by the time that this heroic effort was completed, Kelvin's theory had already been totally discarded as a model for atomic structure. Nevertheless, even without any other application in sight, the mathematical interest in knot theory continued at _ point for its own sake. In fact, mathematical became even more fascinated by knots. The only difference was that, as the British mathematician Sir Michael Atiyah has put it, "the study of knots became a special branch of pure mathematics. " Two major breakthroughs in knot theory occurred in 1928 and in 1984. In 1928, the American mathematician James Waddell Alexander discovered an algebraic expression that uses the arrangement of crossings to label the knot. For example, t2-t+1 or t2-3t+1, or else. Decades of work in the theory of knots finally produced the second breakthrough in 1984. The New Zealander-American mathematician Vaughan Jones noticed an unexpected relation between knots and another abstract branch of mathematics, which led to the discovery of a more sensitive invariant known as the Jones polynomial.

In 1930, Neumann visited Princeton University for a year and then became a professor there.His first book was published in 1932.In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others). World War II hugely changed Neumann's areas of interest.Until 1940 he had been a great pure mathematician.During and after the war, he became one of the best mathematicians who put mathematics theories into practice.During the last part of the war he became interested in computing machines and made several contributions.After the war, Neumann continued his work with computers, and was generally very active in government service.He received many awards, was president of American Mathematical Society and was a member of the Atomic Energy Commission.He died in 1957 of cancer. Neumann really was a legend in his own time, and there are a number of stories about him.His driving ability is a part of this legend.He reported one accident this way: "I was driving down the road.The trees on the right were passing me in an orderly fashion at 60 miles per hour.Suddenly one of them stepped in my path."

Lisa, a 33-year-old woman, went to prepare lunch in the kitchen, leaving Barney, her three-year-old son, playing by himself in the back garden. Suddenly, a sharp cry of Barney came into the mother's ears, and Lisa rushed into the backyard in a hurry and found a big snake entwining the little child with its terrible body and trying to eat the boy as its delicious dish! It was a boa ! Lisa was terrified and quite angry. She made up her mind to save her son from the snake's mouth. It was fearless mother love that made Lisa forget what she faced. She took up an old hoe from the ground and beat the boa with all her might. One...two... With the hoe, Lisa beat the snake repeatedly, but useless. The little boy's voice and breath were getting weaker and weaker. Lisa's heart was broken and she got nearly mad. Suddenly Lisa put away the hoe and threw herself to the boa, opening her mouth and bit into the boa's back as if trying to eat a rare steak . Lisa was really mad! Blood was spurting out of the boa's body and covered most of Lisa's body. The boa was so badly wounded that it let go of Barney and moved back into the forest hurriedly. It had never known how a man had such terrible sharp teeth! On halfway home, the boa died. It was fearless mother love that saved the little boy.

mmlu_stem | mmlu_stem_6544 | Caffeine not only gives us a daily jump start, but new research suggests it also can strengthen long-term memory. According to the US Food and Drug Administration, nearly 90 percent of people worldwide consume about 200 milligrams of caffeine each day. That' s equivalent to about one strong cup of coffee a day. Writing in " Nature Neuroscience" , Johns Hopkins University researchers say their findings show that caffeine strengthens certain memories for up t0 24 hours after being taken in. " We've always known that caffeine has cognitive-enhancing effects , but its ,particular effects on strengthening memories and making them resistant to forgetting has never been examined in detail in humans, " said senior author of the paper Michael Yassa. " We re- port for the first time a specific effect of caffeine on reducing forgetting over 24 hours. " Conducting a double-blind trial, the researchers worked with a test group of people who didn't regularly consume caffeinated products. Five minutes after studying a series of images, the test subjects were given either a placebo or a 200-milligram caffeine tablet. To check the caffeine levels of their test subjects, the research team took saliva samples from them before they took their tablets and again one, three and 24 hours after- wards. Both groups of test participants ( those who took the placebo and those who took the caffeine tablet) were tested the following day to see if they could recognize the images they' d seen the previous day. The test included showing the test subjects another series of images that included some new images , those that were shown the previous day, as well as other images that were similar, but not the same as those they had viewed earlier. The researchers found that more members of the group who were given the caffeine tablets were able to correctly identify some of the new images as " similar" to previously viewed images rather than incorrectly identifying them as the same. "We also know that caffeine is associated with health and longevity and may havesome protective effects from cognitive decline like Alzheimer' s disease . " said Yassa.

mmlu_stem | mmlu_stem_7708 | The UN Environment Programme says that rising temperatures could mean the end for some migrating animals. Migrating or mobile animals move through several environments as they travel away from the cold of winter to warmer areas. Birds may fly from one part of the world to another, perhaps stopping at feeding grounds on the way. Whales and turtles cover vast areas of ocean. The report says that changes in any one of the places which these animals use can cause serious harm. "Obviously these animals have developed their travelling patterns over thousands of years. But climate change is almost certain to be extreme over the next 25 to 50 years and it is extremely unlikely that these animals can change their habits fast enough," said the report author Dr Robert Hepworth. Hardest hit by rising temperatures are turtles. Scientists have found that at higher temperatures, turtles produce far more female eggs than male ones. In parts of Malaysia, turtle birthing sites are producing only females, the report says. It also provides evidence that some turtles are more likely to develop cancer as the waters get warmer. With birds, the main problem is climate-related damage to important areas at either end of the travels or at resting places along the way. About one-fifth of migrating birds are now in danger because of climate-related changes including rising sea levels, land loss and more violent storms, the report concludes. Other animals picked out as particularly in danger include: * the North Atlantic Right Whale, whose main food (tiny shrimp) is disturbed by the change in ocean flows and * the White-Nose Dolphin, which is out-competed by other kinds of dolphins in warmer waters. The report is not all bad news. Even with major climatic changes, protecting the environment can still help mobile animals to recover. "We need governments to start taking action at the national and international lever. "The clock is running." said Dr Hepworth.

mmlu_stem | mmlu_stem_11310 | They survive in some of the coldest environments in the world--but even penguins appreciate a warm woolly jumper once in a while. The mini knitted garments have helped save hundreds of flightless birds caught in oil spills, providing protection from the elements and stopping them from eating poisonous pollution. Knits tor Nature,a program run by The Penguin Foundation,which protects the little penguin population of Phillip Island,140km south-east of Melbourne,has created up to 300 different designs over the years--and it's all thanks to talented volunteers. "There's a lot of hidden creativity out there,"said Lyn Blom,of the Phillip Island Nature Park."People love to know that they're helping the penguins because they're so cute and small and they waddle up the beach and they're so strong and determined.But they need to be,they 1ive in a pretty tough sort of environment.'' A thumbnail--sized patch of oil can kill a little penguin,the smallest of the species,measuring just l3 inches and weighing l kg.The oil separates and mats their feathers,breaking natural waterproofing and heating functions. Ms Blom estimates she has knitted between 200 and 300 penguin jumpers over the years. A staff member read an article in an English women's magazine about knitting for guillemot birds and decided to adapt the designs. "There's a lot of ladies out there who used to knit for their children and grandchildren.These ladies have spare wool and idle hands,and they love to feel loved and needed and we love and need them,"said Ms Blom. The Pengu in Foundation recently staged a competition for the most creative jumper,which received an enthusiastic response. The Penguin Foundation rescues approximately 20 birds a year.They even have a stockpile of jumpers in case of emergency-such as the large oil spill Phillip Island in 2001.

mmlu_stem | mmlu_stem_10802 | 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.

A national team led by two doctors at the University of California, Davis, studied hospital records from thousands of children with head injuries. They found that in many cases, the risk of developing cancer from the radiation outweighed the risk of a serious brain injury. The study found that one in five children over age two had a low risk of serious injury but received CT scans anyway. The same was true of almost one in four children under two years of age. The researchers have developed rules to predict if a head injury is serious enough for a scan. For children under two, doctors are advised against it if there is: *Normal mental activity. *No swelling in the back of the head. *No feeling of a broken bone in the skull. *And no loss of consciousness for more than five seconds. Doctors should also consider how the child was injured and whether the parents say the child is acting normally. For patients from two to eighteen, the guidelines are similar ---- except there should be no l vomiting and no severe headache. Earlier this year, the British Journal of Sports Medicine published new guidelines for concussions in children and teens. International experts said they should not return to sports or school until fully recovered. The brain also needs a "cognitive rest," they say, by restricting activities like video games, texting and watching TV. It often take longer than adults to recover from a concussion than adults. The experts say individual progress and not a set time period should always guide a decision to return to play. How many aspects should doctors consider when deciding whether a child under two needs a CT scan? | [

In any case, you know what it feels like to feel fear. But one woman doesn't the woman, code-named "UM", gave her first-ever interview after years of being studied by a team of researchers. The woman is given a code name because the researchers want to protect her from anyone who would take advantage of her inability to feel afraid. UM can't tell you what fear is because she's never experienced it. "I wonder what it's like to actually be afraid of something," she said. The formal name for the disease is Urbach-Wieth disease, which is characterized by a hoarse voice,small bumps around the eyes, and calcium deposits in the brain. In the case of UM,the disease has transformed the part of her brain that controls the human response to fear. In the interview, UM talks about an event in her life where she was held at knifepoint and gunpoint, "I was walking to the store,and I saw a man on a park bench.He said. "Come here,please," so I went over to him. He grabbed me by the shirt,put a knife to my throat and told me he was going to cut me. I told him, "Go ahead and cut me," I wasn't afraid at all. And for some reason,he let me go." Doctors who have been studying UM's condition for years have been trying different things that could strike fear into her. They finally figured something out--increasing UM's carbon dioxide levels.Extra carbon dioxide concentration in the blood is known to cause fear and panic in health individuals. Increasing UM's carbon dioxide levels did manage to give her a fright. The text starts by _ . | [

When the male is fully grown, he reaches a height of nearly eight feet and many weigh close to three hundred pounds. His wings are very small and the wing feathers are very soft, and therefore he does not fly. You have probably heard the old saying about "the foolish ostrich burying his head in the sand". Well, the ostrich is not nearly as foolish as he is said to be. In the daytime, when the hen is sitting on the eggs, she does not want to be seen; instead of sticking her long neck up into the air, she bends her neck and head down. That way, she can best protect the eggs and herself. Because the ostrich cannot fly up into the air to escape from danger on the ground, he has to remain alert at all times. Luckily, he has very good eyesight and hearing, so he can stop danger in time to run away. The ostrich can run so fast that it almost seems as if he is flying. Sometimes, when a person has a small appetite , we say that he "eats like a bird". Of course, that bird is not the ostrich! An ostrich will eat anything under the sun.

mmlu_stem | mmlu_stem_9291 | In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, the era of digital convergence goes better than yesterday's celebrated "information superhighway." Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each other. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media. The problems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable. Even once global standards are assured, however, a further obstacle lies in wait. The Internet is plagued by long, erratic (,) response times because it is a pull-technology, driven by patterns of user demands. Push-technology, on the other hand, reverses the relationship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom . Besides the issue of consumer habits, infrastructurecosts are set to be immense, and will have to be met by national states or the private sector before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coercedthrough clever marketing to upgrade to newer phones with more features to reinforce their dependence. Whatever the outcome, it is obvious that technology will play an increasing part in our everyday lives. Beyond technology, digital convergence embraces the services, industrial practices and social behavior that form modern society. We have in our hands the technology to construct the most sophisticated machines ever built, but if they are unusable, simply because of their operating instructions, then recent lessons have taught us they will not survive. Whatever we design must be simple, reliable and useful. Perhaps this is where artificial intelligence will come in. By digital convergence, the author means _ . | [

mmlu_stem | mmlu_stem_7399 | The Ministry of Education in Singapore is releasing a new book this month that summarizes the thinking behind the model method for teaching math.The approach has drawn interest from many comers of the world thanks to the country's top performance on international exams.Last night, education officials and researchers from the US and Singapore highlighted some key differences between the two systems. Singapore's method is highly visual and explores fewer topics, but in greater depth.While Singapore's text books have an average of 34 lessons with 15 pages of explanation for each, much bulkier texts in the US include an average of 157 lessons, with about four pages of explanation per lesson.There arc some more surprising differences. Professional development is intensive for all teachers in Singapore, but strangely about half of the elementary teachers do not have university degrees.That is certain to change, though, as education standards for entering teachers are increasing, said Madame Low, the director of curriculum, planning and development with Singapore's Ministry of Education." Starting salaries for math teachers match public sector accountants or engineers.Teachers are treated as professionals," added Madame Low. Mentoring programs for new teachers in Singapore last five years! Teacher evaluations there are extremely comprehensive, and teachers who succeed receive bonuses worth one to three months of salary.Grades one and two have smaller class sizes--only 30 students.Students are taught in English, not their native tongue.Many are bilingual or trilingual. People often ask, how applicable is a successful model in Singapore to the more diverse and much larger US? I'm also interested in the practical challenges.Given that books in the US are written with state standards and assessments in mind, matching them up with another country's approach might be tough.

mmlu_stem | mmlu_stem_7363 | The year of 2014 saw smart people always busy inventing useful things, which have hepled to make the world better, smarter and a little for fun. Now, let's take a look at some of the inventions. Super banana Australian biogeneticist James Dale visited Uganda, a poor African country, in the early 2000s, where he found that 15-30 percent of children under 5 were at risk of going blind because they did not get enough Vitamin A. Dale also learned that people there love bananas. They eat three to 11 bananas a day. So he came up with the idea to plant bananas containing added nutrition in order to improve Ugandans' health. With the help of Bill Gates' foundation, Dale developed the "super banana". He added a gene to the fruit, making it rich in Vitamin A. Coaching basketball Basketball is popular worldwide, partly because you only need a hoop and a ball to play the game. But this simple game has experienced a technology makeover this year with the development of a smart-sensor basketball. The ball, called the 94Fifty Basketball, has nine sensors inside. They can tell you anything from how fast you are going to how accurate your shot angles are. With a Bluetooth chip inside, the basketball can connect to your smartphone and tell you in the voice of a coach to "snap your wrist ", or"go faster", depending on the data. The Hovercraft Thanks to the California-based company Hendo, flying past your friends on a floating board could soon become a reality. The Hovercraft has four small engines. These create a special magnetic field which produce enough force to lift the board off the ground. At the moment, the hoverboard can only float an inch off the ground for 15 minutes and must fly over a metal material. It's expensive too, at $10,000 (61,810 yuan), but the company hopes that one day the technology could be used. Wireless electricity Most of us could not bear to live without wireless Internet. We use it every day for everything from our phones to our cars. But one company wants to go a step further, by combining wireless technology with electricity. That's right, no more tangled wires and no more having to sit and hold your cell phone near a power socket in the corner of the room. WiTricity, a US company, has invented technology that can power objects up to 2.4 meters away. It uses a special plug-in coil that creates a magnetic field! What can we learn about the Hovercraft from the text? | [

Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish. What is the text mainly about? | [

mmlu_stem | mmlu_stem_5056 | Here's an amazing way to get a hard-boiled egg into a bottle, even though the mouth of the boiled is smaller than the egg! What's more, you don't even need to touch the egg to get it to go in! For this experiment you will need: *a hard-boiled egg *a glass bottle with a mouth just slightly smaller than the egg (a fruit-drink bottle works well) *a 8-cm by 8-cm(3-inch by 3-inch)piece of newspaper *a match Remove the shell from the egg. Set the egg on the mouth of the bottle to see that the egg does not fit through the mouth. Light the paper. Remove the egg from the mouth of the bottle and drop the burning paper into the bottle. Before the fire goes out, set the egg back onto the mouth of the bottle. Within a few seconds the egg will squeeze through the mouth and into the bottle. As it entered the bottle, the egg may have broken into pieces. This happens when the diameter of the egg is more than about 0.5 cm(about 3/16 inch) larger than the diameter of the bottle's opening. Why does the egg slide into the bottle, even though no one is pushing it? Because the pressure of the air is pushing it. Before the burning paper is put into the bottle, the pressure of the air inside is the same as outside. The burning paper, however, heats the air inside. This causes the air inside to expand. When the egg is placed on top of the bottle, it seals the bottle. When the fire goes out, the air inside cools. As it cools, the air contracts , and the pressure of the air inside becomes less than the pressure outside. Then, the higher outside pressure pushes the egg into the bottle!

It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break. Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard. Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849. Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats.

mmlu_stem | mmlu_stem_2456 | LONDON (Reuters) -- Children are dying for lack of drugs tailored to their needs, according to the World Health Organization (WHO), which launched a global campaign on Thursday to promote more research into child medicine. More than half of the drugs currently used to treat children in the industrialized world have not been specifically tested on youngsters. The problem is even worse in developing countries where price remains a major barrier and 6 million children die each year from treatable conditions. In the case of HIV/AIDS, the few existing pediatric therapies developed for children generally cost three times more than adult ones. As a result, clinicians lack clear guidelines on the best drug to use and often have to guess at the correct dose. Fortunately, the WHO has drawn up the first international List of Essential Medicines for Children, containing 206 products considered safe for children. "But a lot remains to be done. There are priority medicines that have not been adapted for children's use or are not available when needed," said Dr Hans, the U.N. agency's director of medicines policy and standards. Medicines that need to be adapted to children's needs include many antibiotics, pain drugs as well as combination pills for HIV/AIDS, tuberculosis and malaria. The agency is building an Internet entrance linking to clinical trials carried out in children and will launch a Web site with the information early next year. Testing medicines on children has always been a controversial issue, since good ethical practice requires informed agreement from people participating in clinical trials, which is difficult to obtain in the case of children. As a result, research-based drug companies have been _ of developing child-friendly medicines and general companies have been slow to produce them at lower cost. In an attempt to deal with the issue, both Europe and the United States now have special rules offering extended patent protection for drugs that have been tested on children. Why has testing medicines on children always been a controversial issue? | [

mmlu_stem | mmlu_stem_11208 | For poets, bird song is a beautiful expression of nature in full bloom. But for scientists, the chirps of birds are far more meaningful than just pretty sounds. Latest studies show the way that young birds learn to sing is similar to that of a human baby learning to speak. "The question we're trying to answer is how a young bird learns its song," says Professor Michale Fee of MIT. Bird's creative, trial-and-error type of learning provides an ideal model for studying similar processes in humans. An example is how a baby's babble turns into the recognizable syllables of mama and papa. Also the part of the brain that is involved in bird song is very similar to that of a human. So birds may have something to teach us about our own brains, Fee said. The study shows that young birds like to create new and imperfect songs. Gradually, the youngsters' songs become less different and more similar to the sound of their parents. Scientists disabled part of a young finch's brain and stopped the learning in midstream. The bird still sings. But never learns the right songs. Fee's team found that the part of the brain involved is called the anterior forebrain pathway. Its neurons produce random bursts that make the young bird make new sounds and compared it with that of their parents. They also find out that once a bird is old enough that part of the brain will be less active. The study does not enable us to really understand the meaning of bird language. But Fee believes it will eventually be applied to human brain diseases, such as Parkinson's disease. It can be inferred from the story that _ . | [

Growing a topiary garden takes both time and skills. A topiary gardener should make a drawing first. The drawing shows the final shape that the gardener likes. The gardener then chooses a bush for the topiary. It may be one that just planted or one that is already in place. In June of the plant's first year, the gardener looks for new leaves. When the leaves grow, it's time to shape the bottom of the bush. It needs about five years. The top is not _ during this time. In the fifth year, the bush grows tall enough for shaping. Then the gardener begins to shape the whole bush. Once a topiary has been started, it needs care all year. In the summer it must be cut many times to keep its shape. This cutting also helps the bush grow. In the winter the bushes don't grow. The gardeners have to brush snow off the plants, or snow may hurt some parts of them. Topiary gardening is a very old art. The Romans did it in the first century. In the sixteenth century, people in Europe liked topiaries too. By the late 1600s, topiaries were also grown in America.

"He's seen us through two births, one operation, multiple earaches, a broken wrist and a recovery from a serious traffic crash," says Jill Farrow, a 43-year-old lawyer whose first visit to Dr. Paris was as a teenager. During the birth of her younger son, Farrow began bleeding badly. Dr. Paris managed to solve the problem in a delicate procedure. "Twenty years ago, she probably would have died," he says. Today, when he performs school sports physical examinations for the Farrow boys, 10 and 11, he is always reminded that lives are changed forever by doctors just doing their jobs. To be a mix of country doc and somewhat adventurer, the 55-year-old family physician moved to Hailey after completing his residency . He hoped to practice medicine there and ski at nearby Sun Valley. Unfortunately, the only job opening was for an emergency-room doctor in Missoula, Montana, 300 miles away. Dr. Paris took it. "I'd ski all day and then drive all night to be in Missoula for a 48-hour shift," he recalls. "I'm lucky to be alive." Knowing he couldn't keep up with his eight-hour commute , he began taking flying lessons. In 1981, Dr. Paris joined a small medical practice in Hailey, a former mining town with a population at the time of 2,109. As Hailey grew in the shadow of Sun Valley's booming popularity, Dr. Paris's own practice expanded to seven physicians, including his wife, Kathryn Woods, who is also a family doctor. They met in 1986 at a certification exam in Denver when, in a room full of men in stodgy suits, Woods arrived wearing a Lycra biking outfit and carrying the front wheel of her bicycle (which she couldn't lock up outside).

Once doctors arrive, the chip will also be able to tell them which drugs are not suitable for little Johnny or Janie. At the hospital, the chip will tell doctors his or her complete medical history. And of course, when you arrive to pick up your child, settling the hospital bill with your health insurance policy will be a simple matter of waving your own chip-the one embedded in your hand. To some, this may sound unbelievable. But the technology for such chips is no longer the stuff of science fiction. And it may soon offer many other benefits besides locating lost children or elderly patients. It could be used as credit cards and people won't have to carry wallets anymore. On the other hand, some are already wondering what this sort of technology may do to the sense of personal privacy and liberty. "Any technology of this kind could result in abuse of personal privacy," says Lee Tien, senior staff attorney for the Electronic Frontier Foundation. "If a kid can be tracked, do you want other people to be able to track your kid? It's a double-edged sword." Applied Digital Solutions, Inc. in Palm Beach, Florida, says it has recently applied to the Food and Drug Administration for permission to begin testing its device in humans. About the size of a grain of rice, the microchip can be encoded with bits of information and embedded in humans under a layer of skin. When scanned by a nearby reader, the embedded chip gives the data. Most embedded chip designs are so-called passive chips, which give information only when scanned by a nearby reader. But active chips-such as the proposed Digital Angel of the future-will give out information all the time. And that means designers will have to develop some sort of power source that can provide a continuous source of energy, yet be small enough to be embedded with the chips. In addition to technical problems, many suspect that all sorts of legal and privacy issues would have to be cleared as well. Which of the following statements about Digital Angel is NOT true? | [

But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved .

mmlu_stem | mmlu_stem_7103 | We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently. The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice. It is possible to find out if a person has adapted to the changes of routine by measuring his body temperature because _ . | [

mmlu_stem | mmlu_stem_4281 | The high noise of modern life may affect speech and language development in the very young, according to a study that found the auditory parts of the brains of young mice are slower to organize properly in the presence of continuous sounds. Researchers at the University of California, San Francisco, reared a group of rats in an environment of continuous background noise and found that their brain circuits that receive and interpret sound did not develop at the same rate as animals that were raised in a quieter environment. Edward F. Chang and Michael Merzenich, co-authors of the study appearing in the journal Science, said that the continuous noise delayed the organization of auditory neurons during a critical two-to-three-week period after the rat pups were born. For rats not exposed to the noise, the auditory cortex neurons during this period gathered into a smaller area and began developing a selective response to sounds. But for the noiseexposed rats, this organization was slowed, causing a delay in the development of the ability to discriminate specific sound tones. The researchers said it took three or four times longer for the rats raised in a noisy environment to reach the basic bench marks of auditory development seen in the rat pups not exposed to noises. Although the rat is not a perfect model for what happens in humans, the authors note, the study does suggest that high levels of noise might possibly affect some language learning in babies. "These findings suggest that environmental noise, which is commonly present in contemporary child-rearing environments, can potentially contribute to auditory and language-related development delays,"the authors wrote in Science. The authors noted that although the brain development was delayed in rats exposed to the noise, their brains did eventually mature normally. The findings of the research are said to have special connections with _ . | [

mmlu_stem | mmlu_stem_16198 | All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they create a food chain . Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links disappears. All life needs sunlight to live on. But only plants can use sunlight directly. Plants are 'factories'. They make food from sunlight, water and things in the soil and air. Plants feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly. What about humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses. Each form of life is linked to all others. Breaking the links puts all life in danger.

mmlu_stem | mmlu_stem_10439 | There are no exact differences between physics and other natural sciences because all sciences overlap .In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects. One major branch of physics deals with the states of matter--solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane. A branch of mechanics is statics ,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism ,heat,light,and sound.From these branches of physics scientists find clues which have revealed the constructions of atoms and how the atoms react to various kinds of energy. _ is often called the basis of modern physics.Among the many subdivisions of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the "natural laws" of electricity to help in designing and electric generator .

mmlu_stem | mmlu_stem_12127 | Traffic Management Traffic lights are key tools for regulating traffic How.They are not, however, perfect.Drivers exchange the traffic jams that would happen at unmanaged crossings for a pattern of stop-go movement that can still be annoying, and which bums more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle's speed so that it always arrives at the lights when they are green.That is theoretically possible, but practically hard.Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a crossing, but such signs are expensive, and are not widespread.Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachusetts Institute of Technology, however, have an idea that could make the process cheaper and more effective.Instead of a hardwired network of signs, they propose to use mobile-phone applications. For a driver to benefit, lie must load the team's software , named SignalGuru, into his phone and then put it on a special thing attached to the inside of his car's windscreen, with the camera lens pointing forward.SignalGuru is designed to detect traffic lights and track their status as red, yellow or green.It broadcasts this information to other phones in the area that are fitted with the same software, and --if there are enough of them ?the phones thus each know the status of most of the lights around town.Using this information, SignalGuru is able to calculate the traffic-light schedule for the area and suggest the speed at which a driver should travel in order to avoid red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities.This was particularly impressive because in Cambridge the lights shifted, roughly half-way through the test, from their unbusy schedule to their afternoon-traffic schedule, while in Singapore lights are adaptive, using detectors fixed under the road to determine how much traffic is present and thus when a signal should change.In neither case was SignalGuru fooled. Fuel consumption fell, too --by about 20% .SignalGuru thus reduces both annoyance and fuel use, and makes going back and forth to work a slightly less horrible experience. SignalGuru is an application used on _ . | [

If you didn't sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn't nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day. You should get out of the habit of sleeping during the early evening. Right after your evening meal, engage in some sort of physical activity-a sport such as bowling, perhaps. Or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good night's rest without taking a pill. If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up and watch television or do some jobs around your house until you feel sleepy. If you fall asleep and then wake up a few hours later, get up but do not take a sleeping pill. Read a while or listen to the radio, and make yourself a few hours' sleep that night, you will feel better in the morning than you usually feel after taking a pill.

mmlu_stem | mmlu_stem_8616 | A home computer not only helps children master the old ways of learning, but also opens up possibilities that simply aren't available in traditional education. Some software, for example, allows kids to make decisions and see the results in different situations. The World Wide Web encourages young minds to move easily from link to link, topic to topic. The best software draws children into learning by making them curious--what if I click on this picture, drag this over here, visit that website? Knowing how to use a computer also encourages a child's confidence. Kids figure out quickly that computers are powerful, and mastering the machine makes them feel grown-up. In turn, feeling confident on a computer often translates to academic confidence. Researchers have found that attitudes toward writing, for example, improve when students write on a computer. Perhaps most importantly, computers can enrich family life. Forget the idea that computer kids are separated. Children like to use the computer with adults and other kids, asking questions and comparing results.

mmlu_stem | mmlu_stem_8960 | Eye injuries from paintball games have increased among children, even as the protective equipment for the sport has improved, according to a study released yesterday in the journal pediatrics. The Federal Consumer Product Safety Commission estimated the number of emergency room visits for eye injuries caused by paintballs at 545 in 2001 and more than 1,200 in 2003. More than 40 percent of those injuries were believed to involve children, the study said. Paintballs are fired at a speed of up to 300 feet a second, the study said. Being so small, they can fit inside the bones meant to protect the eye. The study's author, Dr. David A. Listman of St. Barnabas Hospital in the Bronx, said paintball shopping centers had generally switched to full face masks ,which have become more effective at protecting the eyes than earlier _ . But most injuries now occur in backyard play, which is more likely to involve teenagers or children."The injuries being seen are mostly in people who did not wear the proper, or for that matter any, safety equipment,"Dr. Listman said. Those injuries can involve permanent damage to sight, he said. Dr. Listman said he believed that paintball guns should be restricted to regulated places. In the absence of such action, parents should limit children's access to the guns and insist on proper protection.
