Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.

    Researchers, with the help of brain scans, have a shocking differences in perception (感知) between Westerners and Asians, what they see when they look at a city street, for example, or even how they perceive a simple line in a square, according to findings published in a leading science journal.

    In Western countries, culture makes people think of themselves as highly independent individuals. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, emphasize inter-dependence. When Easterners look at a scene, they tend to focus on the surroundings as well as the object.

    Using an experiment involving two tasks, Dr. Hedden asked subjects to look at a line simply to estimate its length, a task that played to American's strengths. In another, they estimated the line's length relative to the size of a square, an easier task for the Asians.

    The level of brain activity, by tracking blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects' brain were different. For the Americans, areas linked to attention were more, when they worked on the task they tended to find more difficult — estimating the line's size relative to the square. For the Asians, the attention areas lit up more during the harder task also—estimating the line's length without comparing it to the square. The findings are a reflection of more than ten years of previous experimental research into East-West differences.

    In one study, for instance researchers offered people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen while Westerners were more likely to choose the green one.

    Culture is not affecting how you see the world, but how you choose to understand and internalize(使内化) it.

    But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us clues to how our brain works and is hopeful for us to develop programs to improve our memory, memory techniques and enhance and accelerate our learning skills.

    Reading makes you a smarter, better leader. But if you've been following the latest science, you'll also know that studies have shown regularly picking up a book might increase your empathy (共鸣) and protect you from feeling lonely, hopeless or suffering from dementia (痴呆) in later life. But obviously, that's not the end of the list. New research has discovered yet another benefit of being a reader who focuses one's mind on reading.

    After following those surveyed based on more than 3,500 adults over age 50 for 12 years, the team from Yale University behind the research found that those who read books for 3.5 hours a week were 23 percent less likely to die. Reading for less than 3.5 hours a week lowered participants' (参加者) risk of death by 17 percent. Put another way, picking up an interesting book could earn you about an extra two years.

    It's worth noticing that the researchers were looking exactly at time spent in reading books, rather than newspapers, magazines, or online media, and that this difference is important for the observed advantages of reading. “We found that reading books provided a greater advantage than reading newspapers or magazines,” said Avni Bavishi of the Yale School of Public Health. “This effect is likely because books attract the readers' mind more — providing more cognitive (认知的) advantages, and therefore increasing the lifespan (寿命). In short, deep slow reading rather than reading quickly and carelessly is best.”

    So how long should you be reading for, and what sort of titles should you pick up? While more reading seems to be better, the researchers suggest that anything more than

    30 minutes a day will be likely to do good to you. As for what exactly to read, the researchers can't yet offer much advice beyond making time for actual books, though they pointed out this was a promising way to future research.

    Who could have imagined that a treadmill（跑步机）on wheels would one day become a thing?!? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question "How can I use a treadmill outdoors?" He finally came up with a new design, adding an electric motor, and the Lopifit was born. It's similar to an electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill, helping you reach a top speed of 17 miles per hour.

    To use the Lopifit, simply turn on the battery（电池）and use your foot to slide the treadmill backwards and start the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast（惯性滑行）, all you have to do is stay still and admire the view. To stop, you have two hand breaks.

    The Lopifit first hit the streets in 2014 and, unsurprisingly, became a hit overnight. That was actually quite challenging for the company, because it started getting calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle could be bought this year, and Lopifit is struggling to keep up with demand, although the price is up to $2,115.

    Some people consider this means of transportation stupid and unnecessary, although there is a very loyal fan-base of so-called Lopifitters. They simply believe that if you're going to walk, you might as well do it the old-fashioned way.

But the Lopifit does have the special advantage of helping you "walk" really fast without much effort, or walking at cycling speed, if you will.

    As computers become more popular in China, Chinese people are more and more depending on computer keyboards to input Chinese characters(汉字). But if they use the computer too much, they may end up forgetting the exact strokes(笔画) of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their homework and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being used more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

    'When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it.'

    'I'm not in the mood to write when faced with a pen and paper.'

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, 'Chinese characters enjoy both practical and aesthetic (审美的)value. But those characters typed with computer keyboards only keep their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's feelings. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.'

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory（必修的）and in universities, some professors are asking students to turn in their homework and essays written by hand.

    How does an ecosystem（生态系统）work? What makes the populations of different species the way they are? Why are there so many flies and so few wolves? To find an answer, scientists have built mathematical models of food webs, noting who eats whom and how much each one eats.

    With such models, scientists have found out some key principles operating in food webs. Most food webs, for instance, consist of many weak links rather than a few strong ones. When a predator（掠食动物）always eats huge numbers of a single prey（猎物）, the two species are strongly linked; when a predator lives on various species, they are weakly linked. Food webs may be dominated by many weak links because that arrangement is more stable over the long term. If a predator can eat several species, it can survive the extinction（灭绝）of one of them. And if a predator can move on to another species that is easier to find when a prey species becomes rare, the switch allows the original prey to recover. The weak links may thus keep species from driving one another to extinction.

Mathematical models have also revealed that food webs may be unstable, where small changes of top predators can lead to big effects throughout entire ecosystems. In the 1960s, scientists proposed that predators at the top of a food web had a surprising amount of control over the size of populations of other species—including species they did not directly attack.

    And unplanned human activities have proved the idea of top-down control by top predators to be true. In the ocean, we fished for top predators such as cod on an industrial scale, while on land, we killed off large predators such as wolves. These actions have greatly affected the ecological balance.

    Scientists have built an early-warning system based on mathematical models. Ideally, the system would tell us when to adapt human activities that are pushing an ecosystem toward a breakdown or would even allow us to pull an ecosystem back from the borderline. Prevention is key, scientists says because once ecosystems pass their tipping point（临界点）, it is remarkably difficult for them to return.

    A small school in rural India is gaining attention over the fact that all 300 students are ambidextrous(左右手都灵巧的). Data shows that only one percent of the global population is ambidextrous, but the ambitious founder of Veena Vandini School, in Madhya Pradesh, is aiming to change that, starting at a local level.

    A former soldier and Veena Vandini School founder VP Sharma stated that he was inspired to focus on ambidexterity training by India's first president Rajendra Prasad who was in office from 1950 to 1962. Unexpectedly, the president was ambidextrous. "I read in a magazine that Dr. Rajendra Prasad, India's first president, used to write with both hands. This inspired me to give it a try, “Mr. Sharma said.”Later when I launched my school at my native village, I tried training the students. "

    "We begin training students from standard Ⅰ and by the time they reach standard Ⅲ, they are comfortable writing with both the hands,” Sharma added. "Students of up to standard Ⅶ can write with speed and accuracy. Further, they can write two scripts at the same time, one with each hand. Students also know several languages, including Urdu."

    Every 45-minute class at Veena Vandini includes 15 minutes devoted to handwriting practice, ensuring that every student develops the ability to write with both hands. VP Sharma also believes that the skill better enables students to learn multiple languages, and has them practice writing the same words in different languages at the same time. Although it is widely believed to help increase concentration, more recent studies have found that this is false and studying to become ambidextrous can, in fact, harm cognitive development.

    A Scientific American study revealed that ambidextrous children performed worse than left- or right-handers on a range of skills, especially in math, memory, and logical reasoning. A study in northern Finland indicated that children who are ambidextrous are much likelier to develop mental health issues, including ADHD, language problems, and academic problems.
