    Read about a normal day in the lives of two children.

    Abbey gets up at 7:00 am, feeds the dog, and has cereal and a glass of juice for breakfast. She walks to school with her friend, Julia. She has a bag of chips for a morning snack, drinks water, and has a chicken and lettuce sandwich with a banana for lunch. She likes to play soccer with her friends at lunch and morning break time. She walks home with Julia, has some crackers with cheese and juice for afternoon snack and plays with the dog for a while. She plays computer games for an hour or two before dinner, then has a shower and does her homework. She watches her favorite television show for an hour, then usually goes to bed at about 9:30 pm.

    Carl gets up at 8:30 am and has two pieces of bread with jam and a glass of milk for breakfast. His mother drives him to school on her way to work. He eats cookies with juice for morning snack and a pot pie ordered from the school lunch room with juice for lunch. He likes to play card games with his friends at lunchtime and climb the fixed equipment at morning break time. He catches the bus home, has a cereal bar and a can of soda for afternoon snack, then watches some television. He has a shower before dinner, then plays the computer for an hour or two. He goes to bed at about 10:30 pm.

    A recent study led by researchers from the National University of Singapore (NUS) has found a clear link between the color of a taxi and its accident rate. An analysis of 36 months of detailed taxi, driver and accident data from two fleets of yellow and blue taxis in Singapore suggested that yellow taxis have fewer accidents than blue taxis. The higher visibility (能见度)of yellow makes it easier for drivers to avoid getting into accidents with yellow taxis, leading to a lower accident rate.

    The study was led by Prof Ho. To test whether there was a causal relationship between the color of a taxi and the number of accidents the taxi had, the research team analysed data collected by the largest taxi company in Singapore. The researchers found that yellow taxis have about 6.1 fewer accidents per 1,000 taxis per month.

    The researchers also studied the economic effect of changing the color of the entire fleet of taxis to yellow. The Singapore taxi company involved in the study owns about 16,700 taxis in a ratio(比例) of one yellow to three blue taxis. If a commercial decision is made to switch from blue to yellow taxis, 76.6 fewer accidents would occur per month or 917 fewer accidents per year. Assuming an average repair cost of $1,000 per car and a downtime of six days, switching the color of all taxis to yellow could produce an annual savings of $2 million.

    "We are eager to continue to validate(证实) the findings of our study by looking at the use of yellow in other types of public transport, such as school buses. For instance, we hope to compare the accident rates of yellow school buses against other colors to find out if yellow is indeed a safer color for school buses. Besides, we are also interested to look at private-hire vehicles and do a comparison of the accident rates of vehicles that are of different colors," explained Prof Ho.

    If you've ever visited London, it's likely that you've heard the loud chimes（鸣响）of Big Ben, the 157-year-old clock bell of the UK's Houses of Parliament（议会）.

    But on Aug 21, the world's most famous bell fell silent. This is because the Palace of Westminster's Elizabeth Tower, which houses Big Ben, needs to be repaired. The workers who'll carry out the repairs don't want their ears to be damaged by the sounds of the huge bell, reported BBC News. Big Ben won't ring again regularly until 2021.

    There's been quite an emotional response to the move. Several members of parliament gathered in front of the Houses of Parliament to hear the bell's last regular chime for four years. A few even shed tears, as if they were attending a friend's funeral.

    But a number of politicians are angry about the lengthy silencing of Big Ben, calling it a symbol of Britain, according to ABC News. And some members of public agree with it. "It's our heritage," David Dummigan, from Cumbria in the north of England, told The New York Times. "People come from all over the world to look at it and listen to it. It's part of British history." This kind of emotional reaction could be linked to "fears about Britain losing its voice and place in the world, which is part of the threat that comes from Brexit", according to CNN. "The reality of losing a place at the top table is being made obvious," it wrote.

    Worries aside, fans of Big Ben will still be able to hear its unique chimes during special occasions such as New Year's Eve. But if we do miss hearing Big Ben on a regular basis, we could always set its sound as our message tone.

    Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted (植入) in their hands. Employees who have these chips can do all kinds of things just by waving their hands. Three Square Market is offering to implant microchips in all of their employees for free. Each chip costs $300 and Three Square Market will pay for the chip. Employees can volunteer to have the chips implanted in their hands. About 50 out of 80 employees have chosen to do so. The president of the company, his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice. Implanting the chip only takes about a second and is said to hurt only very briefly. The chips go under the skin between the thumb and forefinger. With a chip in the hand, a person can enter the office building, buy food, sign into computers and more, simply by waving that hand near a scanner. The chips will be also used to identify employees. Employees who want convenience, but do not want to have a microchip implanted under their skin, can wear a wristband (腕带) or a ring with a chip instead. They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees. Epicenter, a company in Sweden, has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees. The company says scanners can read the chips only when they are within a few inches of them. “The chips protect against identity theft, similar, to credit cards.” The U.S. Food and Drug Administration approved the chips back in 2004, so they should be safe for humans, according to the company.

    In the future, people with the chips may be able to do more with them, even outside the office. Todd Westby is Chief Executive Officer of Three Square Market. He says, “Eventually, this technology will become standardized allowing you to use this as your passport, public transit, all purchasing opportunities, etc.”

    Argument for awards

    It's always exciting every year in October when the Nobel Prizes are announced. We get to witness the acknowledgement (表彰) of some of humankind's greatest minds in six fields – literature (文学), medicine, physics, chemistry, economics and activism for peace.

    This year, however, part of the excitement will be taken away, since there won't be a Nobel Prize in literature due to the fact that the Swedish Academy – the institution (机构) that awards the prize – was involved in a sexual harassment scandal.

People worry that a scandal like this will affect the reputation of the Nobel Prizes. But at the same time, we have to ask ourselves whether we really need these awards after all.

    According to Jana Gallus, an economist from the University of Zurich, Switzerland, one of the reasons that people give out awards is to establish a legacy (遗产). In the case of the Nobel Prizes, they encourage people to achieve more by acknowledging the hard work of top figures in different fields.

    Awards may also help establish standards of what's considered high quality. For example, if you're having a hard time deciding which movie to watch, one of them having an Oscar under its belt will probably help you to make your mind up. And by reading the books that have won The Man Booker Prize or listening to songs that have been awarded a Grammy, you get an idea about what “great” literature and music look and sound like – at least in the eyes of judging panels (评审团).

    Sure, awards can backfire. There was the OscarsSoWhite movement in 2015 and 2016, when it turned out that all 20 actors nominated (提名) for two years in a row were white. There was also the GrammysSoMale movement in January, when Alessia Cara was the only woman to win a solo Grammy this year. But still, it was these incidents that brought the problems of racism (种族歧视) and gender (性别) inequality into the public eye once more. And with influential voices – like that of black actor Will Smith, who refused to attend the Oscars ceremony – the problems became more likely to be noticed and dealt with instead of being buried silently, again.

    Maybe these awards do matter, and we do need them – just not while they are under the shadow of a sexual harassment scandal.

    So when it comes to this year's Nobel Prize in Literature, I'm going to have to say: "No, thanks."
