Our spiritual intelligence quotient(精神智商), or SQ, helps us understand ourselves, and live fuller, happier lives.

    Though we're all born with SQ, most of us don't even realize that we have it. Fortunately, you don't have to sign up for classes to learn how to improve your SQ. Here are some simple steps that can lead you to this new level of understanding.

    Sit Quietly. The process of developing spiritual intelligence begins with solitude(独处) and silence. To tune in to your spirit, you have to turn down the volume(强度) in your busy, noisy, complicated life and force yourself to do nothing at all. Start small by creating islands for silence in your day. In the car, instead of listening to the music, use the time to think. At work, shut the door to your office between meetings, take a few breaths and let them out very, very slowly. Enjoy the stillness in your home after the kids are finally in bed.

    Step Outside. For many people, nature sets their spirit free. Go outside to watch a beautiful sunset. If you are walking with the dog, take the time to admire flowers in bloom; follow the flight of a bird and watch clouds float overhead.

    Ask Questions of Yourself. Ask open-ended questions, such as ‘What am I Feeling? What are my choices? Where am I heading?'

    But don't expect an answer to arrive through some supernatural forms of e-mail. ‘Rarely do I get an immediate answer to my question,' says Reverend Joan Carter, a Presbyterian minister in Sausalito, California. ‘But later that day I suddenly find myself thinking about a problem in a perspective(角度) I never considered before.'

    Trust Your Spirit. While most of us rely on gut(本能的) feeling to realize danger, spiritual intelligence pushes us, not away from, but towards some action that will lead to a greater good.

Multitasking

    What is the first thing you notice when you walk into a shop? The products displayed (展示) at the entrance? Or the soft background music?

    But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop's scent may not be outstanding compared with sights and sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.

    A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers' intension to purchase increased by 80 percent.

    When it comes to the best shopping streets in Pairs, scent is just as important to a brand's success as the quality of its window displays and goods on sales. That is mainly because shopping is a very different experience to what it used to be.

    Some years ago, the focus for brand name shopping was on a few people with sales assistants' disproving attitude and don't touch what you can't afford displays. Now the rise of electronic commerce (e-commerce) has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar stores (实体店) can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this. Now a famous store uses complex man-made smell to make sure that the soft scent of baby powder floats through the kid department, and coconut (椰子) scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store's windows to smell books, pots and drawers, in search of their perfect scent.

    A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

    Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

    In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

    The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo's Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

    One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

    Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

    The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

    In cooperation with German experts, several scientists from the University of Bradford believe that they finally solved a mystery that has been confusing millions of people: why our hair turns gray with age.

    The researchers came up with their results by examining native hair and cells from human hair follicles（毛囊）. They say the secret turns out to be hidden in catalase（过氧化氢酶）, which is causing hair to turn gray.

    Catalase production goes down with age and stress, allowing hydrogen peroxide（过氧化氢） in the hair to do its favorite job—making hair gray, and then white, by blocking the normal production of melanin（黑色素）. Melanin is our hair's natural pigment that is responsible for the color of hair. It also determines the color of our eyes and skin.

    Dr. Gerald Weizmann, an editor of a journal, says," All of our hair cells make a tiny bit of hydrogen peroxide, but as we get older, this little bit becomes quite a lot, and our hair turns gray and then white."

    The new study brings hope for millions of people who have to color their hair: to finally obtain some shampoo that will decrease levels of hydrogen peroxide and therefore restore gray or white hair to its natural color or even prevent it from turning gray.

    The researchers are already conducting an experiment with such a drug on a few volunteers with gray hair and expect to get the results in the next two to three months. If everything works out, millions of people will choose between this drug and other previously used expensive dyes. However, even if the drug works, it will take at least several years before it can be brought to the market.

    On the banks of Tanzania's Lake Eyasi lives the world's last hunter-gatherer tribe (部落) — the Hadza. They don't grow food, raise animals or build houses. Instead they live a life unchanged for more than ten thousand years.

    Their world is one of complete freedom — something modern society can barely imagine and is unlikely to ever experience, let alone have the skills to stay alive. Text messages and phone calls don't exist. Nor do cars and electricity. No jobs, timetables, and social structures. No laws, taxes and unbelievably, no money — the closest thing to currency (交易) is the trade for a pair of shorts with a neighboring tribe.

    We spent our time with the Hadza hunting baboons (狒狒), a daily activity for the men. Their land is packed with sharp bushes, poisonous snakes and man-eating lions. But a successful hunting trip is the difference between eating or going hungry.

    The Hadza diet consists mainly of honey, fruit and meat. Men often hunt in pairs to shoot animals with bows and arrows. The Hadza show us how to track animals, from baboons to snakes to lions. They are hugely skilled with their handmade bows and arrows — we have a go and barely get the arrow to go three feet in front of us.

    The language of the Hadza is believed to be the oldest still-spoken language known to man. The Hadza don't have conflict, and have no memory of starvation. Their population never reaches numbers that cannot be supported through hunting or gathering. They never get from their land more than they need.

    Unlike modern-day office workers, the Hadza enjoy an extraordinary amount of free time. Their “work” — hunting for food — takes up around five hours of their day. They've been in such a state of peaceful existence for thousands of years.

    In 1800, only three percent of the world's population lived in cities. Only one city — Beijing — had a population of over a million. Most people lived in rural areas, and never saw a city in their lives. In 1900, just a hundred years later, roughly 150 million people lived in cities, and the world's ten largest cities all had populations exceeding one million. By 2000, the number of city dwellers exceeded three billion; and in 2008, the world's population crossed a tipping point — more than half of the people on Earth lived in cities. By 2050, that could increase to over two-thirds. Clearly, humans have become an urban species.

    In the 19th and early 20th centuries, many people viewed cities negatively — crowded, dirty environments full of disease and crime. They feared that as cities got bigger, living conditions would worsen. In recent decades, however, attitudes have changed. Many experts now think urbanization (城市化) is good news, offering solutions to the problems of Earth's growing population.

    Harvard economist Edward Glaeser, author of The Victory of the Cir, is one such person. Glaeser argues that cities are very productive because "the absence of space between people" reduces the cost of transporting goods, people, and ideas. While the flow of goods has always been important to cities, what is most important today is the flow of ideas. Successful cities enable people to learn from each other easily, and attract and reward smart people with higher wages.

    Another urbanization supporter is environmentalist Stewart Brand. Brand believes cities help the environment because they allow haft of the world's population to live on about four percent of the land. This leaves more space for open country, such as farmland. City dwellers also have less impact per person on the environment than people in the countryside. Their roads, sewers, and power lines need fewer resources to build and operate. City apartments require less energy to heat, cool, and light. Most importantly, people in cities drive less so they produce fewer greenhouse gases per person.

    So it's a mistake to see urbanization as evil; it's a natural part of development  The challenge is how to manage the growth.
