Texting walkers aren’t just an annoyance to other walkers, Australian researchers armed with movie special-effects technology have determined scientifically that they’re threats to themselves. Using motion-capture technology similar to that used for films, researchers concluded that texting while walking not only affects balance but also the ability to walk in straight line.
“Some people like checking emails while walking to work in the morning,” said the study co-author Hoorn,“but they may not know it has a serious effect on the safety of themselves.” Other facts have also proved this. A tourist walked off a pier(长堤)near Melbourne last month while texting,bringing a sudden and icy end to a penguin-watching visit. Another person who was too wrapped up in his phone to notice dangers walked straight into the fountain in front of a shopping mall.
The Australian study involved 27 volunteers, a third of whom admitted having knocked into objects while texting. They were asked to walk 8.5 meters three times-once without phones, once while reading text and once while writing text, when eight cameras recorded their actions.
They found the volunteers using the phone walked slower, and, more seriously, they locked their arms and elbows in like “robots”, which forced their heads to move more, throwing themselves off balance.“In a pedestrian environment, inability to maintain a straight path would be likely to increase potential for traffic accidents,”said Mr Hoorn. “The best thing to do is to step aside and stop, or keep off the phone.”
Authorities worldwide have taken note. Signs on Hong Kong’s subway system advise passengers in three languages to keep their eyes off their phones. Police and transport authorities have highlighted the danger in Singapore, where the Straits Times newspaper recently declared cell phone-distracted road crossing as “bad habit No.2” contributing to the rising number of road deaths. Some US states, including New York and Arkansas, are considering bans on what they’re calling phone jaywalking.

Because of gravity,cushions between the bones in the spine(脊骨)get compressed(压缩),which makes a person lose a little height and become shorter.
Another reason why some older people shrink is because of osteoporosis(骨质疏松).Osteoporosis occurs when bone is broken down and not enough new bone material is made.Over time,bone is said to be lost.Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.
Older people—especially women,who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis.As years go by,a person with osteoporosis can get small breaks in bones that are called compression fractures.These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over(驼背).
Did you know that every day you shrink a little,too?You aren't as tall at the end of the day as you are at the beginning.That's because as the day goes on,water in the disks of the spine gets compressed due to gravity,making you just a tiny bit shorter.Don't worry,though.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again!
Smoking and drinking alcohol can make this problem worse.Want to do something right now to build strong bones?I believe what I say will help you.

【推荐2】There’s something satisfying about volunteering. Studies have shown that volunteering helps people who donate their time feel more socially connected, thus warding off loneliness and depression. But a growing body of evidence suggests that people who give their time to others might also be rewarded with better physical health, including lower blood pressure and a longer lifespan.
Evidence of volunteerism’s physical effects can be found in a recent study from Carnegie Mellon University, published this month in Psychology and Aging. Adults over age 50 who volunteered on a regular basis were less likely to develop high blood pressure than non-volunteers. High blood pressure is an important indicator of health because it contributes to heart disease, stroke, and premature death.
It’s impossible for this study to prove that volunteering was directly responsible for the lower blood pressure. People who volunteer may be more likely to do other things, like eating a healthy diet or exercise, which lower blood pressure. But the results are in line with other findings on the topic.
How might volunteering contribute to lower blood pressure?Performing volunteer work could increase physical activity among people who aren’t otherwise very active, says leading study author Rodlescia Sneed, a doctoral candidate in social and health psychology at Carnegie Mellon University. It may also reduce stress. “Many people find volunteer work helpful with respect to stress reduction, and we know that stress is very strongly linked to health out-comes,” she says.
A 2012 study in the journal Health Psychology found that participants who volunteered with some regularity lived longer, but only if their intentions were truly altruistic. In other words, they had to be volunteering to help others-not to make themselves feel better.
The Greek philosopher Aristotle once guessed that the essence of life is “To serve others and do good.” If recent research is any indication, serving others might also be the essence of good health.

【推荐3】Stage fright, also called performance anxiety, affects actors of all ages and experience levels, from rookie kindergarteners to Broadway stars. Take Bella Merlin. She’s a professor of acting and directing at the University of California, Riverside. She has also acted for many seasons in several US theaters.Yet, she says,“For seven years, I feared the one thing I loved: acting.”
Signs of stage fright include sweating, rapid breathing, tightness in the chest and “butterflies” in the stomach. Not everyone shows all these signs or experiences them with the same intensity (强度). Yet extreme fear can make some actors escape mid-performance and bring the curtains down on promising careers.
It seems reasonable to blame stage fright entirely on bad-tempered directors or complicated lines. But psychologists have found the physical signs actually reflect deep-rooted fears of one’s own making. Such fears are instances of predicting a negative future outcome without including any other positive alternatives.
What are these fears? One is that of making mistakes. A few actors are afraid any error will ruin their own or their group’s reputation. These may include mispronouncing a word.
For those who have been performing for a while, memories of negative experiences can be an added burden. You’re remembering last year’s school play and imagining your classmates laughing at your errors.This distracts your attention, raising the chance you’ll make another error.
There’s a different worry for actors who put a lot of themselves into their characters. They fear that by not accepting their onstage personalities, the audience is labeling them as “worthless” in real life, too.
Whatever the fear, stage fright activates (激活) a stress-response system in your body. The alarm activating this system comes from an almond-shaped area in the brain called the amygdala. After it sounds the alarm, your body floods with two chemicals: adrenaline and cortisol. They make your heartbeat faster and tighten your muscles, putting you into a fight-fight-freeze mode.
Since stage fright originates in the brain, you might expect the cure exists there, too. You’d be right.

【推荐1】The Banaue Rice Terraces (梯田) in Ifugao Province in the Philippines offer a great sight. This UNESCO World Heritage Site is also rich in history and features how human creativity can produce amazing outcomes. Through hard work, the Ifugao native managed to survive by flattening the mountain’s surface layer by layer and using them as farmlands. This practice of more than two thousand years has put together a well-known wonder.
There are several rice terraces in the Ifugao region but the Banaue Rice Terraces are the most popular tourist spot. The photos of this area are often used in printed materials like textbooks magazines and postcards. After getting a good look at the rice terraces, I was reminded of the first time that I saw their pictures in our textbook during my elementary days. I already found them amusing as a kid and seeing their beauty as an adult got me more amazed.
The tourism officer told us that we were lucky to catch them in their greenest form. If you plan to visit this tourist spot as well, you should take note that we got there last June 1. You can also take into consideration that the rice planting cycle is typically 3 to 6 months.
Unlike the other terraces, the local government created a platform that makes it easy for everyone to get a closer look at the rice terraces. The platform has four stone statues that they refer to as rice protectors.
It’s sad that the younger generation of Ifugaos are slowly abandoning the rice terraces. According to tour guide Alvin, the part of the rice terraces where people can see thick bushes and trees were former rice fields. But the children who inherited (继承) those decided to give up farming and work in big cities instead. I hope that a new farming method with modern equipment will encourage the Ifugaos to continue their rice terraces farming tradition to protect this cultural treasure.

【推荐2】A nerve-zapping(电击神经)headset caused people to get rid of fat in a small preliminary study. Six people who had received the stimulation(刺激)lost on average about 8 percent of the fat on their trunks in four months, scientists reported at the annual meeting of the Society for Neuroscience,
The headset stimulated the vestibular nerve(前庭神经), which runs just behind the ears. That nerve sends signals to the hypothalamus, a brain structure thought to control the body’s fat storage. By stimulating the nerve with an electrical current, the technique shifts the body away from storing fat toward burning it.
Six overweight and obese people received the treatment, consisting of up to four one-hour-long sessions of stimulation a week. Because it activated the vestibular system, the stimulation created the sensation of gently rocking on a boat or floating in a pool, said the study’s co-author Jason McKeown of the University of California, San Diego.
After four months, body scans measured the trunk fat for the six people receiving the treatment and three people who received unreal stimulation. All six in the treatment group lost some trunk fat, despite not having changed their activity or diet. In contrast, those in the unreal group gained some fat. Researchers suspect that changes in the set of life-sustaining chemical transformations within human cells are behind the difference. “The results were a lot better than we thought they’d be,” McKeown said.
Earlier studies found that vestibular nerve stimulation causes mice to drop fat and pack on muscle, resulting in what McKeown called Schwarzenegger mice. Though small, the current study suggests that the approach has promise in people. McKeown and his colleagues have started a company based on the technology and plan to test it further.

More than any other way of gathering evidence, satellite observations continually remind us that each part of the Earth interacts with and is dependent on all other parts.
Earth system science was born from the realization of that interdependence. Satellite remote sensing makes possible observations at large scales, and in many cases, measurements of factors that could not otherwise be measured. For example, the ozone hole over Antarctica--the decrease in the concentration of ozone high in the atmosphere--is measured by remote sensing, as are changes in deserts, forests, and farmlands around the world. Such measurements can be used in many areas of specialization besides Earth system science. Archaeology, for example, has benefited from satellite observations that reveal the traces of ancient trade routes across the Arabian Desert.
New tools for exploring previously inaccessible areas of the Earth have also added greatly to our knowledge of the Earth system. Small deep-sea submarines allow scientists to travel to the depths of the ocean. There they have discovered new species and ecosystems thriving near deep-sea vents that emit heat, sasses, and mineral-rich water.
Just as important as new methods of measurement and exploration are new ways to store and analyze data about the Earth system. Computer-based software programs known as geographic information systems, or GIS, allow a large number of data points to be stored along with their locations. These can be used to produce maps and to compare different sets of information gathered at different times. For example, satellite remote sensing images of a forest can be converted to represent stages in the forest's growth. Two such images, made at different times can be overlaid and compared, and the changes that have taken place can be represented in a new image.

【推荐1】Free and secure accommodation, no bills and even the odd home-cooked meal. It sounds like the perfect living arrangement for cash-strapped students.
Two mothers believe they have devised (提出)a way for struggling students to save on accommodation costs when they leave home to study at university.
Kate Barnham and Amanda Flude have launched Student Swaps, an online accommodation forum (论坛)for parents and students, in advance of the introduction in September of £3,000 higher education top-up fees.
Their website says, “The principle behind Student Swaps is to enable students to literally swap (交换) family homes.” The website will hold a database of students who would like to swap and link them with suitable matches. So those from one town / city could swap with those from a different town / city.
The site describes itself as offering a “cost-free accommodation alternative… at a time of growing student debt”. There is no charge for the service at the moment but Ms Barnham and Ms Flude intend to introduce a £10 annual fee if it becomes established.
However, the National Union of Students (NUS) has warned that, while the scheme may sound appealing to struggling freshers, it lacks any formal regulation.
Veronica King, NUS vice-president of welfare, said, “The fact that this scheme has even been suggested is evidence to the high levels of debt students now face on graduation.” Recent research has shown that students are more likely to live at home in coming years, in a bid to cut down on the cost of a degree.
“This is worrying, as it may mean that students choose their university on the basis of where it is, rather than because it offers the best course for them. It also means students will miss out on what is for some a key part of the student experience—living away from home.”

【推荐2】There was a unique restaurant in London that beat out thousands of stylish restaurants to earn the top ranking on the popular TripAdvisor, despite not existing.
The tale began with a belief that Oobah Butler had developed after a part-time job writing fake(虚假的)TripAdvisor reviews for restaurants: The site was a “false reality”, despite millions of genuine reviews. He decided to see how far he could take a fake restaurant on the site so “The Shed at Dulwich” was born. Butler created a web page with a menu based on emotions and attractive photographs of dishes. He also listed its location as the street he lived on with no address, calling it an “appointment- only restaurant”, to avoid being attacked by fact—checkers.
The Shed was unexpectedly approved by TripAdvisor to be listed in May, starting out as the 18,149th-ranked restaurant in the city: dead last. Butler began having family and friends flood the site with fake reviews. “Spent a weekend in London and heard that this place is a must-visit,” one wrote. “After a few mildly frustrating phone calls I was in.” Soon the customers started calling. “We’re fully booked,” Butler told the would-be diners. However, the restaurant’s reputation started to grow in TripAdvisor’s rankings. Some companies used an estimated location of The Shed on Google to send free samples to Butler, expecting to work with him. In November, Butler received a note from TripAdvisor saying The Shed had become the No.1 ranked restaurant in London!
Butler thought it was time to expose the trick. The story has been praised as an incredible feat(事迹). However, in an era that is increasingly being influenced by all of the disinformation that can be found online, it has also served as another reminder of the ease with which dishonest actors are able to handle online platforms to sometimes unthinkable results.

Instead, she did what a great many people would do—she looked for the best spot to take a selfie (自拍) for her social media accounts. Gayle even admitted that she moved dangerously close to the edge while doing so. It was after that moment that she decided to quit social media.
“I was like ‘this has got to stop,’ ” recalls Gayle. “Taking a photo used to be the first thing I thought about when I got out of the car. Thinking all the time about creating content and worrying about what to say, were taking up too much head space and getting me down.”
Social media can be addictive for many reasons, the main one being that it is a form of escapism, especially for the younger generation. It’s simply a way of connecting without connection, and it’s a 24/7 comfort blanket of company for many. For many of us, most of our time is spent on social media. One global study found that the average person spends 2 hours and 29 minutes per day on such apps and websites. While some people might think that this is a bad habit that they should cut down on, for others it’s an actual addiction that they need help to overcome.
Hilda Burke, a psychotherapist (心理治疗师), says there’s now more widespread awareness about how much time people are spending on social media. “This is now easily to figure up, as most phones show you the breakdown of how you’re spending your time online,” she says. “Seeing how it all adds up can serve as a powerful wake-up call.” She advises that people quitting social media should let all their friends know, so they don’t continue to try to contact you via the sites.
Burke welcomes the fact that more people are quitting social media. It’s likely that we’re eventually starting to realize the damage it can cause to our relationships, mental health and our experience of real-world moments.
