Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

    The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

    Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and he does not.

    The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

    As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

    Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration（合作） between scientists from universities in Turkey and Hawaii.

    The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

    To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos（胚胎）. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

    Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that can be cheaply extracted, especially in countries that can't afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

    The rabbits are expected to have the same life span as their non-glowing counterparts（副本）, but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

    "To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

    Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

    If life is a beach, then a village in Ireland has come back from the dead after the sand returned 33 years later due to a freak tide.

    Dooagh beach on Achill Island in the west of Ireland, was washed away in 1984 after storms hit the area, leaving a rocky foreshore. The tourists left, causing the hotels and guesthouses as well as the cafes to close down. But in April this year, the sand returned over a ten-day period caused by an unusually high tide that deposited hundreds of thousands of tons of sand along the 300m beach, bringing the beautiful beach back to its former glory.

    Emmet Callaghan from Achill Island Tourist Office told the journalist that the people of the island were excited at the beach's reappearing. “It's so nice for the villagers to have their beach back. It is an incredible example of the force and power of nature and how the coast can change in a matter of days. Yesterday we had traffic block here in the village with cars and people coming from all over Ireland and the UK to see our new beach,” he said. “The people here have always spoken about their days on the beach and how they enjoyed it as children. To have it back with their kids is unbelievable. Now locals are hoping that the beach is given the blue flag status. We already have five blue flag beaches and hopefully, if we keep our beach here, we'll have a sixth.”

    Dr Ivan Haigh from the University of Southampton said there were two explanations as to why the beach has reformed. “It could be a change in sediment (沉积物) supply, from further up or down the coast which has brought a fresh amount of sediment to the beach,” he said. “It could also be due to a change in environmental conditions, either a change in the wave climate or a series of tides that have provided the ideal conditions for this beach to reform.”

    The tourism office and locals hope the new beach will stay, at least for the summer of this year.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home still hasn't sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $ 15,000 to $ 20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares to others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    September is an exciting month in every college freshman's life. For many, it's the first time that they've left home to live in a new environment. But after the hustle and bustle（喧嚣）of a few weeks, excitement gives way to a less enjoyable emotion— homesickness.

    Homesickness manifests（显露）itself in many ways. You may miss mum's cooking, your pets, or even your old bed. All this becomes a fond memory of the past. Homesickness can be a bitter feeling for many students, especially when faced with the challenges of settling into an unfamiliar environment.

    But remember, you're not alone. According to a recent BBC article, 70 percent of British college students experience homesickness. In this increasingly globalized world in which people migrate to faraway places for a relationship, education or work, homesickness is a feeling shared by many adults.

    Homesickness can have similar symptoms to depression and in extreme cases it can develop into a panic attack. As for the term, homesickness or nostalgia wasn't invented until the 17th century. It was considered a disorder by a Swiss physician, who attributed soldiers' mental and physical discomfort to their longing to return home, “nostos” from Greek, and the accompanying pain, “algos”.

    Studies in recent years, however, have shown that nostalgia may have some benefits to our mental health. After a decade of surveys and researches, Constantine Sedikides, a US social psychologist, found that nostalgia is what makes us human. He explains that nostalgia can resist loneliness, boredom and anxiety. Therefore, it's necessary for college students to learn some ways to overcome the uncomfortable feeling.

Incredible experiences in Bucharest

    Admire one of the world's largest buildings

    The world's biggest parliamentary building, Palace of Parliament, happens to be in Bucharest. Hour-long guided tours manage to take in just a fraction of the building's three-million-plus square feet (there are more than a thousand rooms) and focus on the tons of marble, hardwood, and gold used in the building's construction in the 1980s, a time when Romania was trying to feed its own people. Ceausescu and his wife, Elena, both played a direct role in the construction. It was originally intended to house the presidential offices and the Central Committee of the Romanian Communist Party but was never finished.

    See remains of old “Paris”

    “Paris of the East” was Bucharest's nickname in the decades before World War II. Decades of communist misrule and a tragic earthquake in 1977 brought much of the old city down but there are places here and there where that former elegance can still be glimpsed. The Cismigiu Gardens in the center of the city is a pearl of park built around a romantic lake and featuring old-growth trees and gracious, wrought-iron signposts and benches.

    Learn about Romania's roots

    Walking though Bucharest's busy streets, it's easy to forget that outside the capital and a U large cities, Romania is a largely agricultural country, with a long and rich peasant tradition. The amazing Museum of the Romanian Peasant shows off the elaborate woodworking, pottery-making, egg-painting, and weaving skills of the peasantry in a way that's both educational and amusing. Small tongue-in-cheek signs at the entrance to each room poke fun at modern life, bring a chuckle, and draw you in. Downstairs there's a side exhibition on the Communists' efforts to nationalize the peasantry in the 1970s and 1980s.

    Appreciate 21st-century art

    Romania has exploded onto the contemporary art scene in recent years. The excitement was generated initially by a group of young painters and visual artists from the northern city of Cluj-Napoca, but at least some of the action has shifted to the capital as new galleries and design centers open up. It's hard to pinpoint precisely what constitutes Romanian contemporary art, though critics point to shared elements of wit and dark humor, a somber mood, and bits of surrealism in defining a common style.
