When the Apollo astronauts (宇航员) landed on the Moon in 1969, millions of people were rather sad. The person to blame for this was an artist named Chesley Bonestell. For many years, Bonestell had been creating beautifully detailed paintings of the Moon and planets. Viewers of his artwork were unhappy because the real Moon did not look like Bonestell's pictures of it.

    As a space artist, Bonestell tried to make his drawings look exciting and as true as the Moon is. He worked closely with astronomers and scientists to get the most up-to-date scientific information available. But in the 1940s and 1950s, no one had ever seen another planet up close. Yet Bonestell's paintings looked so real that some people thought they were photographs.

    Even though Bonestell was interested in astronomy, he did not start out as a space artist. As a young man he studied architecture — the art and science of designing and making buildings. In 1938 Bonestell became a special effects artist in Hollywood. It was here that he learned he could improve his paintings by following the methods used in the movies.

    In 1944, a popular magazine published a series of Bonestell's paintings of the planet Saturn. He drew Saturn as if it were seen by someone standing on each of the planet's moons. The results were dazzling. Within a few years, Bonestell's artwork was appearing regularly in magazines and books on astronomy and space flight.

    Many of Bonestell's artworks had been right all along. But the biggest surprise was the Moon. Someone asked Bonestell what he was thinking when he saw the first pictures from the Moon. “I thought how wrong I was!” he said. “My mountains were sharp (陡峭的), and they aren't on the Moon.”

    But he shouldn't have felt bad. No space artist had ever before taken so many people to so many faraway worlds. In the years just before the first manned space flights, Bonestell's artwork prepared people for the amazing space adventure to come.

    Many people drink coffee to quickly increase their energy. Scientists say there may be another reason to drink coffee. They studied the link（联系）between coffee drinking and the risk of death from some diseases, and found that drinking moderate（适量的）amounts of coffee each day may help protect against heart disease, cancer and other diseases. David Jacobs of the University of Minnesota in Minneapolis worked on the study with researchers from the University of Oslo.

    The researchers used information about 27,300 women. They were between 55 and 69 years of age when they entered the study. During a fifteen-year period, almost 15.75% of them died. The researchers found a link between the amount of coffee the women reported drinking and their risk of dying from heart disease. Coffee drinking was measured in cups. One cup is about 225 grams.

    There was a reduced risk of death from heart disease among women who drank from one to three cups of coffee each day. A reduction（减少）in the risk of death from other diseases was also seen. But Professor Jacobs says the risk reduction for death from heart disease decreased in women who drank more than three cups a day.

    The researchers say antioxidants（抗氧化剂）in coffee might reduce the risk of heart disease. Earlier studies found that coffee has high levels of antioxidants. Antioxidants have been shown to help prevent heart disease, cancer and other diseases.

    US scientists say they have poured cold water on the theory that washing hands with hot water kills more germs (细菌) than unheated water. The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F).

    National Health Service (NHS) recommends that people wash their hands in either cold or warm water. In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water —given to the food industry in the US - held true. They asked 20 people to wash their hands 20 times each with water that was 15C (59F), 26C (79F) or 38 degrees (100F). Volunteers were also asked to experiment with varying amounts of soap. Before they started the tests, their hands were covered in harmless bugs. Researchers say there was no difference in the amount of bugs removed as the temperature of the water or the amount of soap changed.

    Prof Donald Schaffner said: “People need to feel comfortable when they are washing their hands but as far as effectiveness goes, this study shows us that the temperature of the water used did not matter.”

    However, the researchers accept their study is small and say more extensive work is needed to determine the best ways to remove harmful bacteria.

    In the UK, NHS experts say people can use cold or hot water to wash their hands. They say hands should be washed for at least 20 seconds and stress the importance of using enough soap to cover the whole surface of the hands. Their guidance focuses on rubbing hands together in various .ways to make sure each surface of each hand is clean.

    The human brain remembers negative experiences more easily than positive ones. Our brains have developed this way because threats, like dangerous animals, had a more immediate effect on our ancestors' survival compared to positive things like food or shelter. As a result, you likely know what makes you unhappy, but do you know what makes you happy?

    Research suggests that our level of happiness depends partly on factors we cannot control—our genes and our life circumstances. But our level of happiness is also shaped by the choices we make. If you've been chasing wealth, fame, good looks, material things and power, you may be looking for happiness in all the wrong places. Psychologists suggest that the following habits make people happier.

    People who form close relationships tend to be happier than those who do not. The number of friends we have is not important. What matters is the quality of our relationships. Relationships that bring happiness usually involve the sharing of feelings, mutual respect, acceptance, trust and fun.

    People who exercise regularly improve both their physical and mental well being. Some research has shown that exercise can be as effective as medication in treating depression.

    When we are so interested in an activity we enjoy that we lose track of time, we are in a state of flow. The activity could be making art, playing piano, surfing, or playing a game. People who experience flow in their work or hobbies tend to be happier.

    People are more likely to be happy if they know what their strengths are and use them regularly, People who set goals and use their strengths to achieve them tend to be happier. People are especially happy when they can use their strengths to serve the greater good.

    People who think positively by being grateful, mindful and optimistic are more likely to be happy. Being grateful means being thankful, Bejing mindful means being open to, focusing on and enjoying the experiences of the present moment. Being optimistic means being hopeful about the future.

    Scientists, psychologists and English academics at Liverpool University have found that reading the works of the classical writers like Shakespeare and Wordsworth has a great effect on the mind, catches the reader's attention and triggers moments of self-examination.

    Using a special machine, they monitored the brain activity of 30 volunteers as they read works by William Shakespeare, William Wordsworth, T.S. Eliot and others.

    In the first part of the research, the brain activity of 30 volunteers was monitored as they read passages from Shakespeare's plays, including King Lear, Othello, Coriolanus and Macbeth, and again as they read the text rewritten in a simpler form or modern language.

    While reading the common texts, normal levels of electrical activity were shown in their brains. When they read the works of Shakespeare, however, the levels of activity jumped because of his use of words which were unfamiliar to them. The result of the test showed that the more challenging passages cause a greater degree of electrical activity in the brain than the common ones.

    Scientists went on to study the brain activity as it responded to each word and recorded how it lit up as the readers came across unusual words, surprising phrases or difficult sentences in the classical works. As a result, this lightening up process of the mind lasted longer than that when volunteers read common texts, encouraging further reading.

    The research also found that reading poetry especially increases activity in the right hemisphere (半 球) of the brain, an area connected with" autobiographical memory", driving the readers to think carefully about their own experiences based on what they have read. The academics said this meant the classical works of literature are more useful than self-help books.

    Philip Davis, an English professor who has worked on the study in the university's magnetic resonance center, announced this week:" Classical literature acts like a rocket-booster to the brain, which provides extra power for the brain. You may never imagine how powerful it is. The research shows such kind of literature can create new thoughts and connections in the young and the old."
