    When the telephone rings late at night, most women guess it must be one of only four or five people calling. A sister? Maybe. An emergency? Possibly. A mother? Probably not at that time of night. Much more probably it is a close female friend calling to tell you that she has split up with her boyfriend again or perhaps simply that a good movie has just started on TV.

    At a time when families are spread far and wide and marriages often end in divorce, friendships are becoming more and more important. Erika, a 32-year-old lawyer, is strengthened by her ten-year friendship with her married friend Jane. “I was very sick one night, so I called Jane at about 3:00 a.m. to talk about it,” she says. “She was very supportive and even came over to take me to the doctor's the next morning.”

    As American TV shows like Friends, which follows the lives of a very close group of young friends, have become more popular, many of us are beginning to see the value of such friendships. TV shows like this tell us that our romantic relationships may not last, but we need to keep in touch with our close friends if we want to survive.

A TV show called Real Women is about the lives and relationships of five former school friends. In this show, family, husbands, and work are all less important than friendships. One of its actresses says the show reflects her own experience. “Friendship is about commitment. I don't see some of my friends for ages but when we get together, it is as if time hasn't passed.”

    This is true of Erika and Jane's friendship. With Erika's family 200 miles away, it is Jane who keeps a spare set of keys to Erika's apartment and waters her plants whenever she is away. “Having Jane around gives me a certain amount of freedom. It is not the kind of thing that you could ask anyone to do, but she knows I would do the same for her.” Erika feels that because she no longer sees her family every day, she now enjoys a closer relationship with her best friend. Jane, who may move to a different city soon, is worried about leaving such a support system of friends. “My friends have more to do with my life than my parents and, therefore, I don't have to spend a lot of time explaining things to them. Friends are more up to date with what is happening.”

    People have different ways of dealing with a common cold. Some take over-the- counter(非处方的) medicines such as aspirin while others try popular home remedies(治疗)like herbal tea or chicken soup. Yet here is the tough truth about the common cold: nothing really cures it.

    So why do people sometimes believe that their remedies work? According to James Taylor, professor at the University of Washington, colds usually go away on their own in about a week, improving a little each day after symptoms peak, so it's easy to believe it's medicine rather than time that deserves the credit, USA Today reported.

    It still seems hard to believe that we can deal with more serious diseases yet are powerless against something so common as a cold. Recently, scientists came closer to figuring out why. To understand it, you first need to know how antiviral(抗病毒的) drugs work. They attack the virus by attaching to and changing the surface structures of the virus. To do that, the drug must fit and lock into the virus like the right piece of a jigsaw(拼图), which means scientists have to identify the virus and build a 3-D model to study its surface before they can design an antiviral drug that is effective enough.

    The two cold viruses that scientists had long known about were rhinovirus(鼻病毒) A and B. But they didn't find out about the existence of a third virus, rhinovirus C, until 2006. All three of them contribute to the common cold, but drugs that work well against rhinovirus A and B have little effect when used against C.

    "This explains most of the previous failures of drug trials against rhinovirus," study leader Professor Ann Palmenberg at University of Wisconsin-Madison, US, told Science Daily.

    Now, more than 10 years after the discovery of rhinovirus C, scientists have finally built a highly-detailed 3-D model of the virus, showing that the surface of the virus is, as expected, different from that of other cold viruses.

    With the model in hand, hopefully a real cure for a common cold is on its way. Soon, we may no longer have to waste our money on medicines that don't really work.

    Plants are boring. They just sit there photosynthesizing (光合作用) while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution (协同进化) started with ants feeding on plants and plants evolving ant-friendly features.

    Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mаmmаlѕ. Тhеѕе іnсludе hollow thorns that аntѕ will live іnѕіdе, or ехtra nесtаr (琼浆) оn lеаvеѕ or stems for the ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed—often in a nutrient-rich area where it'll grow better, and since it's farther away from its parent, they won't have to compete for resources.

    But scientists weren't sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.

    The history of ants and plants evolving together goes back to the time of the dinosaurs, and it's not easy to tell from fossils who fired the first shot. However, it is a question of little significance. Scientists say their study maters because it provides a look at how these widespread and complex interactions evolved.

    In China, chain restaurants especially the big multinational ones are cool. Going to Starbucks, for example, is a status symbol. It not only says, "I'm rich enough to buy this overpriced coffee, "but also, "I'm cosmopolitan (见多识广的) enough to be part of globalization."

    Where I come from in the UK, however, chains are neither fashionable nor gourmet (美食的). Chains are where you go on New Year's Day when nowhere else is open, or when you are 5 years old and your parents can't stand hearing, "I'm hungry!" any longer. In my own case (with regards to McDonald's), a chain is where you are taken on your first "date". Even at the age of 13, I knew to give the guy the "let's just be friends" phone call the next day.

    In the UK, independent cafes and restaurants are making a comeback on the fashion scene. Nowadays, a Londoner who says "let's meet for a coffee at Monmouth" (an independent café) is much cooler than one who says "let's go to Starbucks". Even if Monmouth's coffee is a little more expensive, there's a satisfaction in knowing your pounds aren't going straight to the big corporations.

    Of course, there are chain stores all over the UK; you can't go five minutes without spotting a Costa Coffee. But numbers do not add up to good taste.

    I do, however, have a confession (坦白). After moving to China I had moments when all the rice and Kung Pao Chicken became too much. I, too, have retreated to McDonald's.

A latest study on people who eat red meat has found they have higher risks of heart disease and early death. The finding goes against other recent research that suggested removing meat from one's diet has few health benefits. The two opposing findings can make it difficult for people to make sense of what can seem to be conflicting messages on food.

Duane Mellor, a dietician at Aston University, and other researchers say that after examining research on the subject, moderation may be the best way forward. "In this case, eating a certain amount of meat, including red meat, is likely to be safe," Mellor said. "However, in the interest of health, reducing meat intake to the recommended less than 70 grams per day would be sensible."

A researcher with ties to the meat industry published a report on the subject in 2019, saying that people should not reduce the amount of red meat they eat. Some experts criticized the findings because they were in conflict with dietary advice from international agencies.

The latest study found that eating two servings a week of red meat or processed meat was linked to a 3% to 7% higher risk of heart disease and also a 3% higher risk of all causes of death. Norrina Allen, a co-leader of the latest study, said the health risk is small but people should try to change their diet. "It's a small difference, but it's worth trying to reduce red meat and processed meat." She added that eating red meat is also regularly "linked to other health problems like cancer."

The World Cancer Research Fund says red and processed meat may cause cancer. It recommends eating red meat with an upper limit of 500 grams cooked weight per week-and "little, if any" processed meat. They said on average, adults should reduce the amount of meat they eat by 50% and they should eat twice as much nuts, fruits, vegetables and beans.
