The Greatest Navigational Journey

    In 1787 Captain Bligh was given command of “The Bounty”, a three-year-old merchant ship. His mission was to transport breadfruit plants from the island of Tahiti to the West Indies. We know the popular story of this voyage and the rebellion, in which Bligh has been presented as hard, violent and thoroughly unpleasant captain. However, there is quite a lot of evidence to suggest that this picture is far from being true. He seems to have been unusually thoughtful about the health and welfare of his men. For example he made sure that his crew got exercise, insisted on cleanliness on his ship, and adopted the practice of giving them a drink which prevented scurvy every day.

    When Captain Bligh arrived in Tahiti, it became clear that it would be some months before the breadfruit trees were ready to be taken to the West Indies. Instead of going off right away, he gave his crew extended shore leave. This may have been a mistake as many were unhappy about leaving when the time came. Finally, on the return journey the rebellion took place. The ship was under the command of the rebels and Captain Bligh had to leave in a small boat.

    Captain Bligh's achievement was to get to dry land successfully. It is one of the supreme examples of seamanship. Apart from Bligh there were 18 members of his crew sailing in an open boat about 23 feet long and 7 feet wide. They took with them 25 gallons of water, 150 pounds of bread and 30 pounds of pork. They had no guns or other weapons. The boat was so low in the water that it seemed likely to sink at any time. On one occasion Captain Bligh tried to land on an island to get more water. He and his men were attacked by hostile natives and one of the crew was killed. At this point Bligh decided to sail directly to the Dutch settlement on the island of Timor without stopping. The distance was about 4,000 miles. The voyage took about 42 days and he had no advanced navigational equipment. However, his skill and commitment proved equal to the task and amazingly no one else died. It was truly a remarkable achievement.

    If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?

    According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.

    The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of “early bilinguals(双语使用者)” who had learnt a second language before the age of five, as well as a number of later learners. Scans showed that grey matter density (密度) in the brain was greater in bilinguals who learnt a second language at an early age. But the longer a person waited before mastering a new language, the smaller the difference. “Our findings suggest that the structure of the brain is changed by the experience of learning a second language,” said the scientists.

    It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. “Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),” he said. “You are actually going beyond language and have a better understanding of different ideas.”

    The findings had the same result in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. “Studying a language means you get an entrance to another world,” explained the scientists.

    Don't you just hate it when you have to take an important phone call and you're surrounded by potential eavesdroppers(潜在偷听者)? You either have to whisper or go outside to keep the conversation private, which is not good. Now Hushme aims to fix this problem by muffling your voice and making you look like Bane in the film Batman.

    Hushme is a strange high-tech mask(口罩)that blocks the sound of the wearer's voice so that people nearby can't hear what is being said. It connects to your phone via Blucetooth and comes with a pair of earphones. When you get a private call, all you have to do is put the mask on and it will do the rest. The pair of thick pads over your mouth does a good job of muffling your voice, but to ensure nothing gets through. Hushme also has speakers that play a variety of sounds when you speak.

    The Hushme mask, which comes in a variety of colors, can be worn around the neck, like a regular pair of earphones, and attaches in front of your mouth thanks to a couple of very powerful magnets(磁铁). It's not yet clear how comfortable speaking with this Bane-like mask over your mouth really is, or how effective its speech muffling ability is, so we know so far is that it makes you look strange. The sound choices for covering your voice currently include wind, ocean, rain, birds, monkey, but new ones could be added in the future.

    Advertised as the “world's first voice mask for mobile phones'. Hushme was showed at CES. At the becoming of this year. Its makers plan to sell it by the end of this year. It will cost about $200.

    In 1996 John Jones made an unusual discovery. He had just enlarged (扩大) a piece of paper money for a friend—a Confederate bank note, money issued (发行) by banks in Southern States of America during the Civil War. When he was face to face with the picture, he couldn't believe his eyes: slaves (奴隶) happily picking cotton in their master's fields.

    Jones grew up in South Carolina. He had heard painful stories of slavery from his greatgrandmother. The picture on the money did not match (匹配) the history of African American slaves that he'd heard all his life. “I had never seen that type of picture on money before,” he said.

    Jones wondered why slaves looked so happy. He started doing research.

    Searching for and finding the answers to his questions changed his life. During two years' search, Jones found more than 120 different bills. He discovered that the bills had several things in common. They showed slaves working in jobs related to farming. Many of them showed healthy and smiling slaves at work. None of the bills showed the hardships of slavery.

    Jones wanted to share what he had learned. “I wanted other people to see what I had seen,” he said. He decided to make large paintings of the pictures on the money. After three years of work, Jones had painted more than 80 slavery scenes (场景).He paired each painting with the money on which the picture appeared. “The Color of Money”—an exhibit (展览) of his work—has toured the country.

    Jones' paintings tell an important story about the South 150 years ago. He likes to repeat the saying. “The story is on the money.” In this case, the saying happens to be true.

    When the fork was stolen off Bart Michiels's mountain bike last summer, he wheeled it nearly three miles from his home in Chelsea to Frank's Bike Shop on the eastern end of Grand Street.

Mr. Michiels passed many other bike shops along the way, including one that offers free coffee. But for 20 years, he has remained devoted(忠实的) to Frank's. “Frank's the man,” he said of Frank Arroyo, the owner. “I don't care where he is in the city — I'll go.”

    Mr. Michiels doesn't have to worry about Mr. Arroyo's relocating (搬迁). The shop has stayed on the Lower East Side of Manhattan for 40 years.

    After Mr. Michiels left, Marvin Priess arrived. A professor of chemistry and math, Mr. Priess wheeled in the Ross 18-speed he had bought at Frank's in 1978 and still rides today, at age 68. Mr. Priess said that over the years, every single part of it that couldn't be repaired had been replaced, sometimes more than once, at Frank's. Customers don't come for the ambience(环境). It's crowded and dirty; buckets of parts and boxes of training wheels line the entryway.

    The store is filled with about 500 bikes and you will find Mr. Arroyo, 72, six days a week. He has been in the bike business since age 14. Born and raised on the Lower East Side, he has employed and taught many young people in the neighborhood. He is also willing to repair bikes in any condition, as well as his neighbors' walkers and wheelchairs.

    English Epps, a lawyer, needed a new seat; his had been stolen. “I've been coming here since I was in the third grade,” he said, adding: “There's a new bike shop on Delancey Street, but everybody comes here.”

    Healthy, convenient and increasingly popular over the past few years, sushi has become as common a dish in the UK as in India or China. It's a popular lunch-choice for city-workers all over the country and you're never far from a restaurant or supermarket selling the traditional Japanese dish. But it turns out sushi may not be as healthy a choice as we thought — leading biologists have warned that it is in fact harming both the environment and our health.

    The UK sushi market is worth £69 million a year, but because we're eating so much of it, the tuna (金枪鱼) population in the oceans is dwindling. According to Professor Daniel Pauly and Dr Dirk Zeller, the leaders of British Columbia, Bluefin and yellowfin tuna populations have reached dangerous levels.

    Bluefin tuna is often served in high-end, excellent sushi restaurants, while yellowfin is more common in high-street sushi bars and supermarkets. Increasing global need means tuna populations are being overfished. Most of the UK's sushi comes from the Indian Ocean, but according to Professor Pauly we now only have 2-3 percent of what we had 200 years ago.

    Professor Pauly and Dr Zeller believe it is our love of healthy tuna that's causing the problems in our oceans. The fish is popular not just for its taste but for its health benefits. But while sushi has earned popularity for being low in calories and high in nutrients (营养物), we may have overestimated (高估) its health value.

    In advance of a lecture at the Zoological Society of London lately, Professor Pauly said he believes most high-street restaurants serve sushi that contains plastic microbeads (塑料微珠). “Microbeads are poison pills which take in all the pollutants and they are eaten by little fish which are then eaten by tuna.”

    So what should we eat instead? Dr Zeller and Professor Pauly are asking the public to step away from sushi and eat more fish like anchovies (凤尾鱼) — less attractive, but better for your health and the environment.
