If you're out for a run, what difference does it make if you're able to tough it out for another 50 seconds? If you're less than a minute from the top of the hill, that extra time can make the difference between having reached your goal and snatching defeat from the jaws of victory.
How do you get those extra seconds of energy? A research team at the Texes Tech University developed a study to measure what effect listening to music would have on exercise tolerance. The researchers based the study on a stress testing. As part of the testing, they noted any changes in heart rate and blood pressure as participants underwent physically stressful exercise.
The tests were done on treadmills (跑步机), which increased in both speed and incline (坡度) through three stages. In the final stage, the treadmills moved at 10 miles per hour at a 14-percent grade. Most of these tests were designed to last up to 40 minutes. The average gym-goers lasted 30 minutes. For this study, they divided 127 participants into two groups. One listened to upbeat(快节奏) music, while the other group had earbuds in but did not listen to music.
The group that listened to music was able to outlast the non-music group by an average of 50.6 seconds. Again, being able to go an extra minute may seem like a no-brainer ,but “after 30 minutes, you feel like you are running up a mountain, so even being able to go 50 seconds longer means a lot," said the study's lead author, Waseem Shami, MD.
The study has confirmed something runners and gym-goers have suspected for years: Listening to music during workout can be beneficial to your endurance. "Our findings reinforce the idea that upbeat music can help you exercise longer and stick with a daily exercise routine," said Shami. When doctors are recommending exercise, they might suggest listening to music, too."

【推荐1】I was speaking to the faculty (全体教师) at John F. Kennedy Elementary School in Canton, Massachusetts, a couple weeks ago. I arrived early and decided to take a walk.
There was a Little League field nearby. I spotted a sign on the fence .
The sign, posted by the Canton Little League, read:
PLEASE REMEMBER
·These are kids.
·This is a game.
·The coaches volunteer.
·You don’t play for the Red Sox (an American professional baseball team).
I had to laugh, especially at the joke about the Red Sox. But I think the sign is a good reminder to everyone connected with youth sports-kids, parents, coaches and the folks who run the leagues-what is important about the games.
First, kids who play are just kids. They are not mini professional athletes. So youth sports leagues and coaches should take it easy on them. Kids don’t need long schedules and lots of faraway games or high-pressure tournaments.
Adults should try to set up youth leagues so more kids play with and against kids from nearby schools and neighborhoods. They should make it easier for kids to play a sport for just a few months so that they can try other sports. Kids shouldn’t play one sport year-round.
And everyone should stop worrying about which team wins or loses. A friend of mine who coached a lot of youth teams once told me, “When you coach kids, it’s not how many you win or lose, but how many sign up for next season.” According to the Aspen Institute’s latest “State of Play” report, fewer kids are signing up. Research indicates a smaller percentage of kids ages 6 to 12 (37 percent) are playing team sports on a regular basis than in 2011 (42 percent).
The aim of youth sports should be to have fun, learn some skills and enjoy being part of a team. When we lose sight of those simple goals, the games suffer, and the kids stay away.
Maybe in 2021 every field or gym where kids play should have a sign like the one in Canton. All you would have to do is change the name of the team.

【推荐2】The stereotype (模式化观念) that girls most enjoy the social side of sport and boys the sense of competition is not to be believed, a study has suggested. In fact, boys and girls are much more similar in what they think makes sport fun than people think, according to researchers in the US.
To gather their findings, a team from George Washington University reviewed an earlier study which looked at what made sport fun for football players aged eight to 19. They found that among the 81 ‘fun’ aspects, winning scored further down than might be expected after it was listed in 40th place. However, they did find some differences in priorities (重点) for what makes sport fun depending on the age or gender (性别) of the young athletes.
Younger players reported it was more important to have a coach who allowed them to play different positions (位置) than older players. Meanwhile boys considered copying the moves of professional athletes and improving their skills to the next level as more important than having fun on the field compared to girls.
The team said their findings, published in Women in Sport and Physical Activity Journal, could be used by sport organizations to make their programs more fun and keep children playing for longer. “When it comes to organized sports, kids just want to have fun,” said Amanda Visek, associate professor of exercise and nutrition sciences at the Milken Institute School of Public Health. “This research does not support the common gender and developmental stereotypes we make about kids in sports.” Dr Visek said their findings made clear girls and boys were “more similar than different” when it came to what made sport fun. “What counts most for girls and boys are things like trying your best, working hard, staying active, and playing well together as a team,” she added. “These findings are the same for athletes of younger and older ages and across recreational and more competitive levels of play.”

【推荐3】Tired of your quiet day-to-day life? How about leaving your computer games behind and taking up an extreme sport?
You can ride a bicycle, right? In that case you’re halfway to becoming a mountain biker. All you have to do is take your bike off the road and try some hilly areas. Mountain biking was developed in California in the 1970s and became an Olympic sport in 1996.
Not challenging enough? Skydivers jump from planes at a height of 1,000 to 4,000 meters. You have to be fit but there’s no age limit with this sport. For example, Dilys Price from Cardiff went on her first jump aged 54. The minute she came down, she wanted to go up again. She said: “It was so attractive”.
Some adventures have invented base jumping, in which people jump from tall structures, such as buildings or bridges, with a parachute. Many of their jumps aren’t legal, especially in the cities.Dan Witchalls has jumped off The Shard —London’s 310 meter-high building four times.He says, “Base jumping is scarier than jumping out of a plane. In a plane there is no sense of height, but when you are standing on the edge of the building you can see people and cars, the experience makes it very real.”
It seems there’s no shortage of imagination when it comes to risking life to look cool and get the heart beating wildly. Surfing, diving, rock climbing ...And how about extreme ironing? That is, pressing your clothes on top of a mountain! Extreme ironing is said to have been created in the 1990s in England by a man who saw a large amount of wrinkled clothes and felt bored when doing the cloth ironing. That man was Phil Shaw. For him, the excitement of this sport comes from looking at the viewers’ faces. Shaw says, “Sometimes they look confused; sometimes they laugh. It’s fun to see how people react to it.”

【推荐1】Highly emotional music causes networks in the brain to release dopamine. This brain chemical plays a role in feelings of pleasure. It also turns on the brain’s motor network that makes us want to move. That physical response to a strong beat can be used to help people with brain-related disorders, research has shown. It aids their ability to time their body’s movements, which can help them with speech issues or trouble moving around.
Olivia Brancatisano, a researcher at Bond University in Robina, Australia, studies music and aging. She found that music can offer a number of benefits, from movement and emotion to communication and thinking. That led her to find music-based therapies (治疗) that might aid people who struggle in these areas.
Older people who have dementia (痴呆) may struggle to remember things. But they did better on mental (精神的) tasks while listening to music they knew and enjoyed. The selected music had to be highly emotional and personal, Brancatisano notes, Listening brought back memories and improved their attention. Since then, she has developed the Music Mind and Movement program for people with dementia.
Music helps young people, too. International students in Australia took part in a recent study at the University of Queensland in St, Lucia. Students may often feel lonely while far from home. Those in the Tuned In program, however, learned to better manage their anxiety using music. They also got better at identifying their emotions. That helped them take action when they were struggling.
The benefits of music seem to cover people of all ages. “We use it to meet basic human needs and to improve our emotional states,” says Brancatisano, “Now, more than ever, we have the ability to engage in music in a variety of ways. We can use it as a tool in everyday life to energize and comfort us.”

【推荐2】What do you usually do to comfort your friends when they are feeling sad or depressed? You probably pat them on the back or shoulder, or maybe you give them a big, warm hug.
We used to think that knowing when and how to comfort others was an ability that only humans have. But scientists have discovered that apes (猩猩)have this ability, too. Two researchers from Emory University in Atlanta, US, went to an Ape Protection Centre in Congo to study bonobos (倭黑猩猩),which are closely related to humans.
The researchers analyzed the bonobos' reactions after more than 370 cases of stressful situations, such as fights and losing temper, and found that some bonobos rushed to hug those that were screaming after being attacked, just like humans would have done.
However, researchers said that not all bonobos were able to comfort others. In the protection centre, many bonobos are orphans (孤儿)whose mothers were killed by hunters. They were found to be more anxious in times of tension and have greater difficulty controlling their own emotions, malting them worse at reaching out to help friends in need.
"Orphans, who have not had the benefit of a mother helping them handling their emotions, are much worse al comforting others,” Professor Frans de Waal, one of the researchers, told The Telegraph. "Bonobos with moms were able to curb their negative emotional reactions more quickly. Therefore, they pay more attention to others.” This pattern mirrors the way that human children have been found to react. Those who seem more capable of handling their own emotions—for example, the ones who can calm themselves down more quickly after upsetting experiences—are usually better at expressing their concerns for others .

【推荐3】People who grow up outside of cities are better at finding their way around than urbanites, a large study on navigation suggests. The results, described online on March 30 in Nature, hint that learning to handle environmental complexity as a child strengthens mental muscles for spatial skills.
Nearly 400,000 people from 38 countries around the world played a video game called Sea Hero Quest, designed by scientists and game developers as a fun way to collect data about people’s brains. Players piloted a boat in search of various targets.
On average, people who said they had grown up outside of cities, where they would have probably encountered lots of complicated paths, were better at finding the targets than people who were raised in cities.
What’s more, the difference between city residents and outsiders was most obvious in countries where cities tend to have simple layouts (布局), such as Chicago with its streets laid out at 90-degree angles. The simpler the cities, the bigger the advantage for people from more rural areas, cognitive scientist Antoine Coutrot of CNRS and his colleagues report.
Still, from these video game data, scientists can’t definitively say that the childhood environment is behind the differences in navigation. But it’s possible. “As a kid, if you are exposed to a complex environment, you learn to find your way, and you develop the right cognitive processes to do so,” Coutrot says.
Other factors have been linked to navigational performance, including age, gender, education and even a superior sense of smell. Figuring out these details will give doctors a more precise baseline (基准) of a person’s navigational abilities. That, in turn, might help reveal when these skills weaken, as they do in early Alzheimer’s disease, for instance.

【推荐1】I came home one day recently and, for reasons I don’t quite understand, my living room smelled like my grandmother’s house. Suddenly I felt as if I were 12 years old, happy and relaxed, sitting in her kitchen. I can remember what her house looked like, though it was sold 20 years ago — her three-level plant stand, the plates lining the walls, the window over her sink — but these visual memories don’t have the power that smell does. The funny thing is, I can’t even begin to describe the odor that was so distinctively hers. The best I can do is this: “It smelled like my grandmother’s house.”
It’s a common experience, and a common linguistic problem. In cultures worldwide, people have powerful olfactory memories. This odor-memory link is also called “the Proust phenomenon,” after Marcel Proust’s famous description of the feelings aroused by a cake dipped in tea in “Remembrance of Things Past.”
Olfactory memories seem to be more closely bound up with emotions than are visual or auditory ones.
Not all these memories are pleasant, of course, and smells can also trigger feelings of pain.
It is surprisingly hard for English-speakers to describe the odors that occasion such strong emotions, however. English possesses almost no abstract smell words that pick out links or themes among unrelated aromas.
We have plenty of these in the visual field. “Yellow,” for example, identifies a characteristic that bananas, lemons, some cars, some flowers, old book pages, and the sun all share.
But for odors, we don’t have many more than the vague “musty” (smells old and stale) and “musky” (smells perfumey). We usually have no choice but to say that one thing smells like another—like a banana, like garlic, like diesel fuel.
A few languages, though, do have a rich odor vocabulary. Linguist Asifa Majid has found that the Jahai, the Semaq Beri, and the Maniq, hunter-gatherer groups in Malaysia and Thailand, employ a wide range of abstract smell words and can identify aromas as easily as we can colors. The Jahai have a word, for example, that describes “the seemingly dissimilar smell of petrol, smoke, bat poop, root of wild ginger and wood of wild mango.”
Last year my cat got sprayed by a skunk, and the vet told me to wash its face with coffee to cover the bad smell. Until then, I had never realized that coffee, which I find delicious, smells remarkably like skunk spray, which I do not.
Science has identified the chemicals that both share. They are called mercaptans. But in oral English, we have no word for the underlying note that connects these two odors. If the Jahai drank coffee and encountered skunks, I bet they would.

【推荐2】“Mona Lisa’s” famous smile is routinely described as ambiguous. But is it really that hard to read? Apparently not. In an unusual trial, close to 100 hpercent of people described her expression as “happy”.
The “Mona Lisa” is often held up as a symbol of emotional mystery. Kornmeier, the German scientist, and a team used it in a study of factors that influence how humans judge visual clues such as facial expressions. Using a copy of the masterpiece by Leonardo da Vinci, the team moved the model’s mouth corners slightly up and down to create eight altered images. They created four “happier” and four “sadder”“Mona Lisas”.
A block of nine images were shown to 12 trial participants 30 times. In every showing the pictures were randomly rearranged. Then participants had to describe each of the nine images as happy or sad.
“Given the descriptions from art and art history, we thought that the original would be the most ambiguous,”Kornmeier said. Instead, “we found that Da Vinci’s original was perceived as happy in 97 percent of cases.”
The second experiment involved the original “Mona Lisa” with eight “sadder” versions. These were given even more subtle (微妙的) differences in the lip tilt (倾斜). In this test, the original was still described as happy. However, participants’ reading of the other images changed. “They were perceived a little sadder than in the first experiment,” said Kornmeier.
The findings confirm that “we don’t have an absolute fixed scale of happiness and sadness in our brain”—and that a lot depends on context, the researcher explained. Understanding this process may be useful in the study of psychiatric (精神病学的) disorders. As for the masterpiece itself, the team believe their work has finally settled a centuries-old question.

【推荐3】The idea that animals can remember past experiences seemed so absurd that few researchers bothered to study it. Surely only humans could be capable of “episodic” memories — recalling a trip to the grocery store last Saturday, for example. We now know that we were mistaken — and a study from the animal world might even help us improve how we treat Alzheimer’s disease(阿兹海默症).
Crystal and her students conducted a study of whether animals are capable of episodic memory. First, they trained 13 rats to memorize 12 odours(气味). They built a special rat “area” with 12 stops, numbered 1 to 12, each scented with a different odour. When the rat identified the odour in a particular stop on the route, such as second-to-last or fourth-to-last, it received a reward. Then the researchers changed the number of odours and watched to see if the training had taken hold: would the rats identify the second-to-last and fourth-to-last odour in the sequence(次序), even if the number of odours was different? This ensured that the rats were identifying the odours according to their position in the sequence, not just by smell. “We wanted to know if the animals can remember a lot of items and the order in which those items occur,” Crystal said.
After a year of these tests, the team found that the rats succeeded in the task about 87 percent of the time. Further tests confirmed that their memories stuck with them, and wasn’t influenced by other memories.
The new genetic tools such as gene-editing allow scientists to create rats with an Alzheimer’s-like condition, making them the perfect subjects to test new Alzheimer’s drugs. In the United States alone, the number of people suffering from Alzheimer’s will increase from 5.8 million today to 14 million by 2050 as the population ages. If rats with episodic memory can help to break the Alzheimer’s code, this thief of the past might finally be defeated.

【推荐1】Josh Katz works at the New York Times. His common job is to use information to tell interesting stories. In December 2013, Katz built a quiz on the Times website. It asked people about the words they used to describe things and events. It also asked how they pronounced common words. The quiz then used people’s answers to decide where in the United States they were from.
The quiz got more than 350, 000 results. Katz turned the results into a book. In Speaking American, he studies regional differences in how Americans talk.
“A lot of people’s language shows who they are and where they are from, in a very personal way”, Katz said.
Katz says people are often surprised to learn that the way they talk can show where they grew up. Most Americans don’t realize they use regionalisms --- or words and phrases specific to a particular part of the country. But just about everyone does. Almost every major U.S. city has a few unique terms. For example, in Philadelphia, Pennsylvania, the night before Halloween is known as Mischief Night. Anyone who calls it that is likely to be connected to the city.
Katz himself was surprised by how many common words are regional. “There are a lot of words I use that I just thought were standard words,” he says. “Then I found out some of these words were actually a product of my upbringing.”
For example, he says, “I thought everyone said ‘sneakers’ (运动鞋) and not ‘tennis shoes’.” But it turns out “sneakers” is connected mostly to the Northeast. That’s where Katz is from.
Some scholars think that language in the U.S. is growing more homogeneous (同类的). But Katz disagrees. “These regional differences are here to stay.” he says.
Not only are people still using common regionalisms, but there are new ones appearing all the time, according to Katz. There’s no way to predict how language will change in the future. But Katz sees more changes coming. “The only sure thing about language is that it’s going to keep moving.” he says.

The Westborough High School golf team had taken the official photos with the state prize. The other teams, disappointed, were on the bus heading home. And then Westborough instructor Greg Rota noticed something wrong on one of the score cards. A 9 had been recorded as a 7. They were not the state prize winner; Wobum High had won. "No one would have known," said Wobum's instructor, Bob Doran. For Rota, it wasn't a difficult decision: "The prize wasn't ours to take."
Coin Stars
"College students are lazy, but they also want to help," says University of Pennsylvania graduate Dana Hork. So she made it easy, placing cups in rooms where students could leave their spare coins, and handing out cups to first-year students to keep in their rooms. Her " Change for Change" effort has collected $40,000 for charities (慈善机构) , which were decided upon by students.

【推荐3】Australia and New Zealand’s health organizations have given their advice on when to use sunscreen (防晒霜), suggesting Australians apply it every day to avoid bad health effects.
A Sunscreen Summit took place in the Australian State of Queensland. During the summit, representatives from some of Australia’s leading research, medical and public health organizations examined the evidence on sunscreen use the determined that in most parts of the country it is beneficial to apply sunscreen every day.
“Up until now, public health organizations have recommended applying sunscreen ahead of planned outdoor activities but haven’t recommended applying it every day as part of a morning routine (惯例),” professor Rachel Neale from QIMR Berghofer Medical Research Institute said. “In recent years, it has become clear that the DNA damage causes skin cancer and melanoma (黑色素瘤), which is caused by repeated small exposure to sunlight over a period of time,” Neale said. “In Australia, we get a lot of sun exposure from everyday activities such as walking to the bus stop or train station,” Neale said.
A study showed that one in two Australians believed it was unhealthy and potentially dangerous to use sunscreen every day. However, Terry Slevin from the Public Health Association of Australia says it is wrong. “There is consistent and compelling evidence that sunscreens are safe,” Slevin said. “Importantly, medical trials have found that people who use sunscreen daily have the same levels of vitamin D as those who don’t,” Slevin added.
Australia has one of the highest rates of skin cancer in the world, which is made worse by the country’s close to Antarctica where there is a hole in the ozone layer (臭氧层), letting in higher numbers of UV rays.
