mmlu_train_9221 | Freezing weather can mean frostbite and _ unless a person is prepared. Do you know how to stay warm, dry and safe in such cold winter? Frostbite is damage that happens when skin is exposed to extreme cold for too long. It mainly happens on the hands, feet, nose and ears. People with small cases of frostbite that affect only the skin may not suffer any lifelong damage. But if deeper tissue is affected, a person is likely to feel pain every time the area gets cold. If blood vessels are damaged, people can suffer an infection of gangrene . Sometimes, doctors have to remove frostbitten areas like fingers and toes. Hypothermia happens when the body cannot produce as much heat as it releases. The condition comes on slowly. Signs of hypothermia include uncontrollable shaking, very slow breathing and unclear thinking. If not treated properly, Hypothermia can be deadly. A simple way to avoid cold-related injuries is to remember four basic steps. Think of COLD -- C.O.L.D. The C stands for cover. Wear a hat and a scarf to keep heat from escaping through the head, neck and ears. And wear mittens instead of gloves. In gloves, the fingers are separated, so the hands might not stay as warm. The O stands for overexertion . Avoid activities that will make you sweaty. Wet clothes and cold weather are a bad mix. L is for layers. Wearing loose, lightweight clothes, one layer on top of another, is better than wearing a single heavy layer of clothing. Also, make sure outerwear is made of material that is water-resistant and tightly knit. Can you guess what the D in C.O.L.D. stand for? D is for dry. In other words, stay as dry as possible. Pay attention to the places where snow can enter, like the tops of boots, the necks of coats and the wrist areas of mittens. And here are two other things to keep in mind -- one for children and the other for adults. Eating snow might be fun but it lowers the body's temperature. And drinking alcohol might make a person feel warm. But what it really does is weaken the body's ability to hold heat. Which of the following is NOT true about the C.O.L.D. according to the text? | [
"They are four basic steps to keep warm.",
"Gloves can't protect us from cold sometimes.",
"We should keep ourselves as dry as possible.",
"They can protect us from injuries completely."

mmlu_train_32274 | The deep sea is one of the most mysterious places on earth. Scientists rarely go there. Those few do discover new species all of the time. Many places of the deepest parts of the ocean, where it's forever dark, can light up. Now, a teen's research has shown new light on how one of these swimming animals behaves in darkness. The giant flashlight fish lives in the Indian Ocean as well as in tropical parts of the central and western Pacific. It lives at depths of up to 400 meters, (about 1,300 feet). But not always. Sometimes it lives in coral reefs in shallow waters. In those shallow waters, the blackish-blue fish comes out only at night. Reef-dwelling members of this species tend to be smaller than those living in deeper waters. Those biggies can grow to lengths of 35meters (14inches). That may not sound like a giant, but they are the largest of their type of fish. The giant flashlight fish gets its name from a small glow-in-the-dark patch found in a packet of tissue under each eye, explains Caroline Edmonds. She is a 13- year-old student from Fountain Valley, Calif. There, she attends Talbert Middle School. She said that the eye pockets in these fish contain light-producing bacteria. These bacteria and their host fish have built a relationship that helps both. The fish use the bacteria as a way to communicate with creatures around them. The bacteria gain nutrients from the fish and a safe place to live. When a fish wants to " flash" its light, it turns the bacteria-filled pocket toward the outside of its body, Caroline explains. When a fish wants to hide its light, it turns the pocket back toward the inside. According to her data, the fish flash most often when they are being fed. They flash least often late at night, when they are resting. The deep sea is dark and mysterious, but _ | [

mmlu_train_62014 | We don't have beds in the space shuttle, but we do have sleeping bags. During the day, when we are working, we leave the bags tied to the wall, out of the way. At bedtime we untie them and take them wherever we've chosen to sleep. On most space shuttle flights everyone sleeps at the same time. No one has to stay awake to watch over the space plane: the shuttle's computers and the enginers at the Control Office do that. If anything goes wrong. The computers ring a warning bell and the engineers call us on the radio. On the space shuttle, sleep-time doesn't mean nighttime. During each ninety-minute flight around the earth, the sun "rises" and shines through our windows for about fifty minutes: then it "sets" as our flight takes us around the dark side of the Earth. To keep the sun out of our eyes, we wear black sleep masks. It is surprisingly easy to get comfortable and fall asleep in space, and we sleep differently. Some sleep upside down, some sideways, some right side up. When it's time to sleep, I take my bag, my sleep mask, and my tape player with earphones and float up to the flight platform. Then I get into the bag, and float into a sitting position just above a seat, right next to a window. Before I pull the mask down over my eyes, I relax for a while, listening to music and watching the Earth go by under me. When I'm in space I don't need as much sleep as I do on Earth Maybe that's because when I am weightless, I don't feel as tired. Or maybe it's because I'm excited to be in space and don't want to waste time sleeping. During sleeping time, the job of watching over the shuttle is done by | [

mmlu_train_11416 | Scientists have searched for many years for a method to tell whether a volcano explosion will be small or large. Now, four scientists say they have discovered something in lava that will help do this. They did the research on Mount Unzen on the southern Japanese island of Kyushu. Mount Unzen exploded in November, 1990. Since then, more explosions have killed 43 people and destroyed the homes of more than 2,000 others. The volcano is still active today. The scientists say the lava of the volcano contains high level of an element ,which is a sign of the presence of the lava from deep in the earth, not from the surface. They say it shows that the lava coming directly from inside the earth is connected with huge explosions instead of smaller ones. The scientists examined the lava from 18 explosions of Mount Unzen that took place during many thousands of years. They also studied the lava from other volcanoes in the area that are older than Mount Unzen. The lava studied came from both large and small explosions. The scientists found that large explosions contained more of the element than small ones. The scientists say if they had known this two years earlier, they could have warned the people living in the area near Mount Unzen and saved many lives. Scientists have searched for a long time in order to _ . | [

mmlu_train_31531 | The German shepherd runs off and noses around in the grass of Kenya's Laikipia Plateau. "OK, Oakley," the dog's handler orders, "Find it!" Oakley sniffs until he comes to a bush, then stops, sits, and looks up at his handler. She bends to see what he has found: the waste of an endangered African wild dog. "Good dog!" she praises. The handler pulls a tennis ball from her pocket. Oakley jumps for his reward. "He doesn't actually want the waste," says Aimee Hurt, a founding member of the U.S.-based group Working Dogs for Conservation. Hurt is in Kenya to train both Oakley and his handler. "He finds it so he can play with his ball. We're the ones who want the waste." Detection dogs are sometimes taught to locate actual animals. Black-footed ferrets have been studied with their help. But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions. What the dogs find provides scientists with data about a species. Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes -- all without ever seeing the animal itself. "It can take years to gather this kind of information if you have to trap animals," Hurt explains. Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock . Hurt says, "A good detection dog will find the waste so we can see what the animal is actually eating." This may help reduce problems between people and wildlife. Oakley is interested in finding the waste because _ . | [

mmlu_train_17583 | Doctors have a new weapon in the battle against obesity -- a talking plate that tells people not to eat too quickly. The Mandometer monitors the amount of food leaving the plate, and tells users, "Please eat more slowly." The PS1,500 Swedish device is to be used in a National Health Service plan to help hundreds of obese families lose weight. It comes in two parts -- a scale placed under the plate and a small computer screen showing a graphic of the food gradually disappearing as the user eats. A red line on the screen shows the user's eating speed, while a blue line shows a healthy rate. If the user eats too fast, the red line angles away from the blue one, warning him or her to _ . If the lines deviate too much, the computer voice comes on, and the screen flashes the message "Are you feeling full yet?" to remind users to think about whether they have had enough. Britain has an increasingly serious obesity problem, with one in four adults and one in seven children classed as obese. After a recent trial using the device, experts believe teaching obese people to eat more slowly will help them know when they are full. Around 600 families with at least one obese parent and child (aged five or older) were targeted in the project by Bristol University, along with GPs and nurses. Professor Julian Hamilton-Shield, who is leading the plan, says obese children and adolescents using the Mandometer ate from 12 to 15 percent less per meal at the end of the 12-month trial. Six months after they stopped using the device they still ate less, and continued to lose weight. "It will be a powerful tool to help families retrain their eating habits," he says. Which of the following is TRUE, according to the text? | [

mmlu_train_42502 | For most Chinese university students, the prefix = st1 /USis a favorite destination for further education. But apart from obstacles such as the GRE and TOEFL exams, choosing a good graduate school is no easy task. Admission is very competitive for international students, so it is important to apply to a number of institutions to have a reasonable chance of acceptance. Since the application to most universities requires a certain fee, Chinese students usually choose seven to 17 universities according to their own financial circumstances. Wang Yuwei, a Zhejiang University graduate, sent applications to 15 USuniversities. When the 24-year-old began looking for a USgraduate school in her senior year, she took time to compare the various schools and find the ones most suiting her needs. Now, studying at theUniversityofWashington, she knows that her hard work paid off. "To broaden your chances, at least one third of the applications should be to less selective schools," said Wang. "Applicants shouldn't limit their choices to the most famous institutions." Furthermore, one shouldn't rely on too much on college rankings such as the Gorman Report or US News & World Report's annual league tables. The right school is the one that best meets your own personal needs and interests, rather than someone else's assessment of an institution's prestige .

"These findings suggest that living with both parents may prevent drug use."said Dr.McArdle,of Newcastle University in northern England, who led the study."They also suggest that attachment ,particularly to mothers,is a more effective factor and that this is truly across cultures and substances."The report, which is published in the journal Addiction, involved nearly 4,000 teenagers in England,Ireland,Italy,Germany and the Netherlands.They were questioned about their use of several kinds of drugs and alcohol.The teenagers also filled in questionnaires about their relationship with their parents and grandparents, how well they were supervised after school and whether they were allowed to meet friends at home. "Both the quality of family relationships and the structure of families have significant influences on youth drug use," McArdle said in a statement.But he added that a strong offered the greatest protection against developing drug habits.The rate of drug abuse among teenagers living with both parents and who had a good relationship with their mother was 16.6 percent.If either factor was missing, the drug abuse rate rose to 32 percent.More than 42 percent of teenagers living in one parent families who did not have a strong bond with their mother used drugs.

mmlu_train_16837 | Pierre is a 25-year-old penguin at the California Academy of Sciences.Due to his old age,he was going bald,which made him feel too cold to swim in the pool.Therefore,biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool. Unlike marine mammals,which have a layer of blubber to keep them warm,penguins depend on their waterproof feathers.Without them,Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water. "He was cold:he would shake,"said Pam Schaller,a senior biologist.Schaller first tried a heat lamp to keep Pierre warm.Then she got another idea:if wetsuits keep humans warm in the cold Pacific,why not make one for Pierre? Schaller designed the suit,which covered Pierre's body and had small openings for his flippers. "I would walk behind him and look at where there were any gaps.and cut and refit until it looked like it was extremely suitable."she said. One concern was that the other penguins would reject Pierre in his new suit,but in fact,they accepted his new look.He swam freely and got along with others well,although he was the only penguin with a black stomach. Schaller couldn't say for sure whether the wetsuit allowed Pierre to recover his fine feathers,but" certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable".

mmlu_train_41496 | "Enough" with the multivitamins already. That's the message from experts behind three new studies that tackled an often debated question: Do daily multivitaminsmake you healthier? "We believe that the case is closed - supplementing the diet of well-nourished adults with (most) mineral or vitamin supplements has no clear benefit and might even be harmful," concluded the authors of the editorial summarizing the new research papers. They urge consumers to not 'waste' their money on multivitamins. "The 'stop wasting your money' means that perhaps you're spending money on things that won't protect you long term," editorial co-author, Dr. Edgar Miller said, "What will protect you is if you spend the money on fruits, vegetables, nuts, beans, low fat dairy, and things like that. Exercising would probably be a better use of the money." The strong message was based on a review of the findings from three studies that tracked multivitamins link to cancer protection, heart health, and brain and cognitive measures. The first study looked at vitamin supplementation's role in preventing chronic disease. The next study looked at whether long-term use of multivitamins would have any effect on slowing cognitive decline. The third study looked specifically at multivitamins and minerals role in preventing heart attack. "The three studies found no difference in rates of chronic disease, heart attack and the need for hospitalization between vitamin-takers and placebo -takers." Dr. Edgar Miller stated. One expert agreed some nutrient-deficient people may still benefit from multivitamins. "There might be an argument to continue taking a multi(vitamin) to replace or supplement your not healthy diet," Dr. Edgar Miller added.

mmlu_train_23196 | When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science. Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material--some of it unearthed by miners in Alaska--to conclude that today's domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man's best friend may have enabled the tough journey from Asia into North America. "Dogs may have been the reason people made it across the land bridge," said Wayne. "They can pull things, carry things, defend you from fierce animals, and they're useful to eat." Researchers have agreed that today's dog is the result of the domestication of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America's domestic dog was that Natives domesticated local wolves, the descendents of which now live with people in Alaska, Canada, and the Lower 48. Dog _ from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of "pure native American dogs," Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America. Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge. Leonard and Wayne's study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. "Dogs must have been useful because they were expensive to keep," Wayne said. "They didn't feed on mice; they fed on meat, which was a very guarded resource."

mmlu_train_35549 | Since the Internet came into homes, the daily life has never been the same again. But the thing that worries most of us is that we can get viruses from the Internet. But can we catch viruses on our cell phones? A new study in the journal Science says yes, but the spread of such mobile software that can bring harm to our cell phones won't reach dangerous levels until more cell phones are on the same operating system. Computers are easily attacked by viruses because they share data, especially over the Internet. Of course, nowadays, more people are using their cell phones more and more frequently. They use them for emailing, text messaging and downloading troublesome ring tones, etc.,so it is obvious that cell phone viruses are a threat as well. Scientists used nameless call data from more than six million cell phone users to help model a possible outbreak. And they concluded that viruses that spread from phone to phone by Bluetooth are not much concerned, because users have to be in close physical relation for their phones to "see" one another. However, viruses that spread through multimedia messaging services can move much faster, because they can come in disguise , such as a cool tune sent by a friend. The good news is that to be effective, these viruses need their victims to all use the same operating system, which not enough of us do. Because there is no Microsoft operating system for mobile phones, yet. Thank goodness. We can learn from the passage that _ . | [

In all , 12 American astronauts have walked on the moon , the last - Eugene Cernan and Harrison Schmitt - doing so in 1972 . Enthusiasm for space travel has always decreased and increased . In 2010 , President Barack Obama cut funds for a NASA mission that would have put humans back on the moon by 2020 . " I understand that some believe that we should attempt a return to the surface of the moon first , as previously planned . But I just have to say here : We've been there before , " Obama said . NASA Administrator Charles Bolden has also thrown cold water on the idea of a return mission to the moon . But others believe there are benefits to going back to the moon . " It's the closest body to us , making it the least challenging to explore of all the planets , moons and asteroids in our solar system , " wrote Gene R. Grush , from NASA Johnson Space Center . " It's an opportunity to establish a permanent presence off Earth - a moon base for scientists or a colony for all of humanity . " " There is a lot of good science on the moon that we've only scratched the surface on , " said former astronaut Tom Jones . Richard Vondrak , from NASA's Goddard Space Flight Center , agrees , saying , " Astronauts can accomplish scientific exploration that is beyond the capability of robotic explorers . " And then there's the private business . In the last few years , several private companies - including Elon Musk's SpaceX - have launched rockets of their own , ending the national control over space flight . NASA is even considering a partnership with SpaceX , and Musk has said that if demand to go to the moon exists , his company will help fill it . Meanwhile , Buzz Aldrin , the second person to walk on the moon , believes that there's a much better target for exploration : Mars .

mmlu_train_27405 | A man enters a store to buy milk. He walks out of the store with milk. That is all--milk. At the same time, a woman enters the same grocery store also to buy milk. She buys it. But, she also buys chicken and lemons to make dinner that night. She also gets a bottle of wine for drinks with friends and a birthday card for her husband's niece. And that is the difference between the female and male brains simply explained in a grocery store. Generally speaking, men do one thing at a time. Women do many. Doing many things at one time is often called "multi-tasking," a very popular word these days. Now scientific research supports this theory about male and female brains. A recent study has confirmed what we have known all along--men and women think differently. Scientists at the University of Pennsylvania studied brain images of 949 people aged from 8 to 22 years old. They found that male brains have more connections on one side of the brain, or hemisphere. In the female brain, they found more activity and connections between the right and left sides of the brain. The left side of the brain is known as the side of "reason". The right hemisphere is known as the "creative" side. Regina Verma is a professor at the University of Pennsylvania. She co-wrote the report. She says when women are asked to do something complicated they might use different parts of the brain. But men generally use just one. As a result, men generally deal directly with a problem. There is a strong connection between the "understanding" and the "action" parts of their brains. Women, however, might include other parts of the brain, like the part connected with "reason" and the part connected with sensitivity when solving a problem. Women take a less direct path to find a solution. Thanks for your listening. I'm your announcer Anna Matteo. Where does this passage probably come from? | [

Pasta has become popular, for one thing, because it is cheap and easy to prepare. Just cook noodles or other forms of pasta, make a sauce to go with it and you're finished. Many different types of meals can be created with pasta. It tastes good and fills your stomach. It produces energy in the form of carbohydrates , which is why athletes eat pasta regularly. Pasta can also be kept for a long time. You don't have to use it up at once. Pasta has also become popular because it stands for the Italian way of life. People all over the world like it because it's so simple. It has two basic ingredients, wheat and water, just like bread. Before it became popular in Italy during the 19th century, earlier civilizations also ate pasta. Legend has it that Marco Polo brought pasta back to Italy with him but this is not true. Arabs probably brought a noodle-like dish to Sicily in the 8th century. Farmers have been growing wheat, the main ingredient of pasta, there for ages. The worldwide sales of pasta have risen sharply over the past decade. $16 billion worth of pasta were sold in 2010, compared to $13 billion worth of the favorite food in 2003.

One excellent source of vitamin A is found in sweet potatoes with orange flesh.Orange sweet potatoes contain high levels of beta-carotene ,which our body can change into vitamin A. Experts say orange sweet potatoes specially bred (,) for growing conditions in Africa could help solve the lack of vitamin A there. But, first, more people will need to be persuaded to eat them. Jan Low with the International Potato Center, a research organization says the sweet potato needs a better image in Africa. Jan Low says,... We do have an image problem with sweet potato in general in sub-Saharan Africa. It is seen as a crop of the poor. " Ms Low explains that sweet potatoes are mainly grown by poor women to feed their families in case another crop fails. The sweet potatoes commonly grown if Africa have white or yellow flesh. But, more importantly, they are low in vitamin A. Jan Low took part in a project to study how best to market orange sweet potatoes to Africans.She worked on an information campaign in Mozambique and Uganda.The campaign included radio messages about the nutritional benefits of the orange sweet potato.They advertised its ability to" fight diseases, make you strong, clear your skin and make you look healthy." In areas without radio, the campaigners spread the message through community theater.The performances included singing, dancing and storytelling.And everywhere they went, the campaigners wore orange T-shirts and hats.They even drove orange vehicles.Jan Low says the color1 made it easier to gain public attention. Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization. He points to efforts in the past to increase the popularity of other nutritious crops. He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat.But Mr.Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa.

mmlu_train_47697 | One Monday morning, Paul and his classmates were in science laboratory for their practical chemistry lesson. The students were going to work in pairs to do an experiment. Before they began, the teacher gave them this description of the different stages of the experiment. Stage 1: Prepare the equipment: a test tube, a crucible, a Bunsen burner and tongs. Stage 2: Weigh 5 grams of baking soda (sodium bicarbonate) and put it in a crucible. Stage 3: Heat 10 ml of hydrochloric acid in a test tube. Stage 4: Pour the warm acid onto the baking soda and continue to heat the mixture. Result: The acid reacts with the bicarbonate to form water, carbon dioxide gas and salt. The hotter the mixture, the quicker the reaction. Continue to heat the mixture until the water evaporates, leaving the salt in the crucible. Paul and his partner followed the instructions and set up their equipment. Paul went to the cupboard to get a bottle of hydrochloric acid. He found that there was only one bottle in the cupboard so he took that. There was no label on the bottle and Paul didn't check with the teacher if it was the right solution. He measured the liquid and poured it into a test tube. Using tongs to hold the test tube, he heated it over the Bunsen burner. That's when things started to go wrong. The liquid in the test tube was not hydrochloric acid. When it was heated, it formed a thick cloud of white gas. Soon the room was full of this strong smelling white gas. All the students started coughing and their eyes hurt. The teacher immediately opened the windows and ordered the students to leave the laboratory at once. She realized that the liquid was a crylamide and that it is poisonous. Fortunately, nobody was injured in the incident. However, it taught the students and the teacher a good lesson. Why did the teacher send the students out of the classroom? | [

mmlu_train_17717 | Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health. This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased.Apple, for example, doesn't want iP hones to come closer to you than 1.5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters. If health issues arise from cell phone use, the implications are huge.Voice calls - Americans chat on cell phones 2.26 trillion minutes annually - generate $109 billion for the wireless carriers. Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled. Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population. "Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says. Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains. Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.

mmlu_train_28978 | It just may be the world's most costly vacuum cleaner ( ). The price of CleanSpace One is eleven million dollars. But yet, it has a big job to do. Recently, researchers in Switzerland said they planned to build this new cleaning machine. CleanSpace One will not be for use in homes or businesses. It will be shot into space to help remove thousands of pieces of space junk floating around up there. Last year, we reported on the problem of space junk. Over time, many unused spacecraft have hit each other far above the Earth. Big pieces break into thousands of small pieces. Sometimes they fall back into the atmosphere and burn up. But when they do not, it creates big problems. Scientists fear that if something is not done to remove these objects, it may soon become too dangerous to send people and machines into space. There is a large chance that they might hit some of this junk. So that is why the Swiss researchers are developing the new machine. CleanSpace One is not really a vacuum cleaner. It will not be used to take away space junk. But scientists plan to move it close to an old satellite that is no longer being used. Then a claw-like instrument will catch the satellite, and force it back through the atmosphere. There, the satellite will be destroyed by the heat of friction with the air. Researchers say that all they need to do is slow down the speed of some of these unwanted objects. Once they begin to move more slowly, they will fall back to the Earth. There is little chance that they will fall through the atmosphere and harm the people or things below. Unwanted objects will fall back to the Earth when _ . | [

mmlu_train_31772 | WASHINGTON(Reuters)-People who drink two or more sweetened soft drinks a week have a much higher risk of pancreatic cancer , an unusual but deadly cancer, researchers reported on Monday. People who drank mostly fruit juice instead of sodas did not have the same risk, the study of 60,000 people in Singapore found. "Sugar may be to blame but people who drink sweetened sodas regularly often have other poor health habits," said Mark Pereira of the University of Minnesota, who led the study. "The high levels of sugar in soft drinks may be increasing the level of insulin in the body, which we think contributes to pancreatic cancer cell growth," President said in a statement. Writing in the journal Cancer Epidemiology, Biomarkers & Prevention, Pereira and his colleagues said they followed 60,524 men and women in the Singapore--Chinese Health Study for 14 years. Over that time, 140 of the volunteers developed pancreatic cancer. Those who drank two or more sweetened soft drinks a week had an 87 percent higher risk of being among those who got pancreatic cancer. Pereira said he believed the findings would apply elsewhere. "Singapore is a wealthy country with excellent healthcare. Favorite pastimes are eating and shopping, so the findings should apply to other western countries." he said. But Susan Mayne of the Yale Cancer Center at Yale University in Connecticut was cautious. "Although this study found a risk, the finding was based on a relatively small number of cases and it remains unclear whether it was a causal connection or not." Said Mayne, who serves on thee board of the journal, which is published by the American Association for Cancer Research. Pancreatic cancer is one of the deadliest form of cancer, with 230,000 cases globally. In the United States, 37,680 people are diagnosed with pancreatic cancer in a year and 34, 290 die of it.

mmlu_train_92312 | There is a saying, "An apple a day keeps the doctor away." Although eating properly is important, being kind to others is also good tor your health. Studies show that people who perform kind acts are more relaxed, happier, and healthier than other people. In one study at Arizona State University researchers, found that many volunteers experienced a sudden feeling of joy, followed by a long period of calm, after performing a kind act. This feeling, called "a help's high" may actually help reduce stress as the body releases naturally painkillers. Stress can cause' serious health problems, and heart depression, and .sleeping problems. However, the study found that volunteers had fewer *stress-related health problems when they did helpful things for other people. The study also found that people who did nice things for others felt better about themselves as well. They had higher self-esteem , and were' happier. Many believe this is because volunteers spend more of their time with other people. People who are more outgoing are often healthier. Another study at the University of Michigan's Survey Research Center confirmed the health benefits of volunteering. A ten-year study showed that people who volunteered live longer than those who didn't. Although you shouldn't need a reason to be helpful, it is nice to know that kindness may help you live longer.

Norma didn't travel alone.She brought about 100 companions along with her.Norma was an ant, a queen ant who, with her subjects, made up the first ant colony to travel into space.The ants were part of a science experiment designed by the students to test the effects of weightlessness on insects. The equipment designed by the students for their colony functioned perfectly throughout the long space trip.The young scientists and their teachers were very sad to find that their insect astronauts had all died at some point before the container was returned to the school and opened.The problem did not occur in space, but on the ground after Challenger had landed.The container remained in the desert for nearly a week before the ant colony was removed.The hot, dry desert air dried out the colony's container and the ants died from lack of moisture . The project was termed a success because it did provide useful information.Students will continue their efforts to find out exactly what went wrong.They will try to prevent the same difficulties from recurring on future missions .They don't want to be discouraged either by the death of the ants or by the $10,000 shuttle fare they will have to pay to send the next colony of ants into space.
