    Have you ever wondered why the roots of the plants always know which way to grow—into the soil but not above it? Some British scientists have recently solved this mystery.    

      It turns out that roots have special hairs that tie them into the soil and help them grow their way past obstacles, a team at the John Inners Center in Norwich reports in the February 29 issue of Journal Science.

    "The key is in the fuzzy(有绒毛的) coat of hairs on the roots of plants," says professor Liam Dolan. "We have found a growth control system that enables these hairs to find their way and to become longer when their path is clear."

    Root hairs explore the soil in much the same way a person would feel their way in the dark. If they come across an obstacle, they make their way around until they can continue growing in an opening. I the meantime, the plant is held in place as the hairs grip the soil.

    The hairs are guided by a clever chemical trick. A protein(蛋白质) at the tip of the root hairs called RHD2 helps them to take calcium(钙) from the soil. Calcium makes the hairs grow, and produce more RHD2, and take more calcium.

    But when an obstacle blocks the hair's path, or the hair reaches the surface of the soil, the cycle is broken and growth starts in another direction.

    This system gives plants the flexibility to explore a complex environment and to live in even the most unpromising soils, says Dolan.

    In poor soils such as in parts of Australia and Africa, native plants have adapted by producing enormous numbers of root hairs. A better understanding of this adaptation will allow scientists to develop hairy rooted crops that can grow in unfriendly environments.

    According to Dolan, "Research in the John Inners Center is taking a breeding approach(育种方法) to increase hair length in wheat but it will be some time before new cultivars(栽培变种) are developed."

    In the early 1980s, one of our neighbors asked my mom if she would make a few gift baskets for her to give as gifts for the holidays. My mom agreed and news of the unique gift baskets my mom was making spread like wildfire throughout the neighborhood. My mom was busy throughout the holiday season, so she asked a friend to help her. When the orders continued after the holiday season for baby gifts, birthday gifts and more, it occurred to them that maybe this job could be turned into a business and they did it.

    My mom went into her business because she had creative ideas. She got orders and filled order. But there was no goal and no real plan. In 1991, my mom's partner got into financial trouble and there was not enough money to support either mom or her partner.

    So if you are led by your creativity or enthusiasm, make sure you ask yourself what you purpose to do your business is. If you don't set goals, how will you know which direction to go in? Do you want to create jobs and growth in the economy? Are you looking for a hobby? You can't keep scores if you don't know what game you are playing.

    After my mom's partner quit, she had to abandon her business to support herself. She swore she would run a business again and do it differently the next time. However, there wasn't a “next time” for her. She passed away just after her 51st birthday. She never had someone tell her how important having a goal was, she never had a chance to be everything she could be.

    There are no right or wrong goals, only the ones that matter to you. Set them so that you can make progress and achieve success, whatever they may mean to you.

    Japan is aging faster than any other nation. By the end of this decade, there will be three retirees for every child under 15 and before long, one in six people will be over 80. Its population will soon be falling by nearly a million people every year and some people predict that, some time in the next century, the last Japanese person will die. Other countries are encouraging immigration to deal with their demographic woes. But not Japan, which is using different ways to reduce pressure put on health care and social services.

    The Toto-made toilet, common in Japanese hotels, can push up to help the elderly. Now Toto is working with Daiwa House, Japan's largest house builder, to equip toilets for retirees. These have medical sensors that measure blood sugar levels, the blood pressure and body fat of the user. The data is emailed to the local GP through a built-in internet device (装置). So make sure you eat your greens and stay regular, or the doctor will be in touch.

    The over-75s account for more than a quarter of the deaths in car accidents on Japanese roads. Toyota is working with Professor Kawashima, who developed brain training games for Nintendo, to create intelligent cars that monitor brain activity in the elderly. Other technologies could also work to keep elderly drivers cautious.

    Japan has twice as many pets as it has children. But real animals are difficult to look after as their owners age. Paro is a furry white baby seal robot which responds to petting by moving its tail and opening and closing its eyes. It shows emotions such as surprise, happiness and anger, and has sold well in nursing homes where it is reported to stimulate (刺激) responses among those with dementia (痴呆).

    Japan's Institute of Physical and Chemical Research has developed Riba, a nursing care robot that can lift the elderly out of bed.

    Ever order a drink, and feel cheated on the pour? Before you trouble the waiter, take a closer look at the size of your glass. “People will generally think there being less in larger containers, than in smaller ones.” Says Theresa Marteau, a behavioral scientist at the University of Cambridge, in England.

    She and her workmates had analyzed(分析)how larger amounts—and larger plates—trick us into eating more food. And they wondered: could the same be true for alcohol?

    So the researchers convinced the employees at a local bar to run an experiment: every two weeks, for four months, they'd change the bars wine glasses from the standard 300 milliliter size, to either slightly larger—370 milliliters, or slightly smaller—250 milliliters. They saw how the size of the glass affected customers' drinking habits, even though the pour, the amount of alcoholic drinks, was unchanged.

    It turned out that serving wine in smaller glasses had no measurable effect. But the large glasses increased wine sales 10 percent-even after controlling for day of the week, temperature, holidays and so on. The reason? “When the wine, the same amount, is being served in a larger glass, people are probably thinking they've got less in there.” Which, she says, means they might drink more, believing they haven't hit their nightly limit. Or, they might just feel less satisfied with the pour, and buy another round. The study appears in the journal BMC Public Health.

    Marteau says that, if later studies confirm this effect, public health officials might consider directing a certain average glass size. “Stating clearly the largest size in which wine can be sold could be a measure to reduce the overconsumption(过度消耗)of alcohol that seems to be shown by the glass size.” Until that happens, the bar in the study now always serves its wine in the larger glasses.

    As an old saying in China goes, “The days of the Sanjiu period are the coldest days.” “Sanjiu period” , which is in Minor Cold, refers to the third nine-day period (the l9th to the 27th day) after the day of the Winter Solstice(冬至). There are many different customs related to Minor Cold in China.

    Eating hotpot

    During Minor Cold people should eat some hot food to benefit the body and defend against the cold weather. Winter is the best time to have hotpot and braised mutton with soy sauce. But it is important to notice that too much spicy food may cause health problems.

    Eating huangyacai

    In Tianjin, there is a custom to have huangyacai, a kind of Chinese cabbage, during Minor Cold. There are large amounts of vitamins A and B in huangyacai. As huangyacai is fresh and tender, it is fit for frying, roasting and braising.

    Eating glutinous rice (糯米饭)

    According to tradition, the Cantonese eat glutinous rice in the morning during Minor Cold. Cantonese people add some fried preserved pork, sausages and peanuts and mix them into the rice.

    Eating vegetable rice

    In ancient times, people in Nanjing took Minor Cold quite seriously, but as time went by, the celebration of Minor Cold gradually disappeared. However, the custom of eating vegetable rice is still followed today. The rice is steamed and is unspeakably delicious. Among the ingredients (原料), aijiaohuang (a kind of green vegetable), sausages and salted duck are the specialties in Nanjing.

    Chewing gum(口香糖) has its origins in ancient times from Mayans to Greeks who would chew the resin(树脂)of certain trees for medical purposes and maybe even for freshening breath. The history of chewing gum continued as Native Americans introduced it to European settlers.

    Chewing gum hit the market after Santa Anna brought a case of chicle(糖胶树脂) from Mexico to New York. Santa Anna gave some to the part-time inventor Thomas Adams Thomas Adams changed the gum and marketed it as a candy. The invention took off and was known as Chiclets.

    In 1900 Frank Fleer coate chewing gum with sugar, and in 1906 Blibber Blubber was invented, but never made it to market. Blibber Blubber was too sticky and it was also too difficult to remove the burst bubble(破了的泡泡) from one's skin without using some special tools.

    A history of bubblegum just wouldn't be complete without mentioning the gumball machine, which popularized gum. The first gumball machine came onto the scene in 1907 and sold sugar-coated chewing gum.

    However, it wasn't until 1928 that bubblegum was created. Walter Diemer, working for Frank Fleer's gum company, discovered bubblegum by accident while experimenting in the lab during his breaks. The gum was named Dubble Bubble. Pink was the only color which could be used at the time, and Dubble Bubble has remained pink ever since.

    According to the International Chewing Gum Association,during WWII Dubble Bubble was handed out by US military members as gifts, thereby spreading its popularity among the peoples of Europe, Africa, and Asia. And in the 1930s he first bubblegum cards appeared. "the pictures changed from war heroes to Wild West figures to professional athletes."

    Bubblegum has been popular ever since, especially among children, thanks to its inventive shapes, and sugary flavors, from original bubblegum to a yardstick of fruity bubblegum.
