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 less difficult 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 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.

    They 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 will 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, the color of all taxis to yellow could produce an annual saving 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 example, we hope to compare the accident rates of yellow school buses against those of other colors to find out if yellow is indeed a safer color for school buses. Besides, we' re 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.

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions(同伴) than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    Coca-Cola has created a publicity stunt (作秀) in Singapore — a vending machine (自动售货机) which gives out free cans of Coke in return for (作为对…回报) hugs. The whacky idea is part of the company's Open Haziness campaign (运动) designed to attract young people in Singapore.

    Students at the National University of Singapore were surprised to find that the soft drinks company had placed the machine in the schoolyard. But instead of the drinks brand's logo (标志), the words “Hug Me” are written across its red-and-white logo. Instead of paying money, customers have to hug the drinks machine to receive a free can of Coke.

    Public displays of affection are uncommon and have long been discouraged in Singapore, but are on the rise among young people. The move is part of a campaign created by advertising firm Ogilvy & Mather, intended to let the youth to see the brand as a non-threatening (无威胁的) friend.

    Leonardo O'Grady, leader of the campaign, said, “Happiness is contagious (传染的). The Coca-Cola Hug Machine is a single idea to spread some happiness. We want to spread happiness in an unexpected, creative way to attract not only the people present, but the audience at large.”

    He hopes that it will encourage consumers to bring positivity, optimism (乐观) and fun into their lives and to open a Coke, sharing a little happiness.

    The machines haw been such a success that there are plans to roll them out across Asia. Mr. O'Grady added, “The reaction was amazing — at one point we had four to five people hugging the machine at the same time as well as each other! In fact, there was a long line of people looking to give hugs.”

    Full House was an American television show from the 1980s to the 1990s. It was among the most popular TV shows of its time. The show followed a single father who asks his friends to help him raise his three young girls. The last episode (集）of Full House aired in May 1995.

    But on Friday, the No 1 trending topic on Twitter in the U.S. was Fuller House. The new show is the long-awaited sequel (续集）series that follows the now-adult characters from Full House. The streaming service Netflix released 13 episodes of the new series at midnight Friday.

    Fuller House trended throughout the night and into Friday morning on Twitter and Facebook. The actors on the show were among :he :op 10 U.S. Google searches, as well Longtime fans of Full House admitted that they stayed up all night to watch the entire season.

    Excited fans tweeted about having waited more than 20 years for the sequel. But some viewers were not impressed with Fuller House. And television critic Hank Steuver of The Washington Post called the show, “a retread' He says the show is not some golden treasure* of family-friendly programming.

    Although most of the main characters from the original Full House have returned for Fuller House, the show's youngest character, Michelle Tanner, refused. Michelle was played by twins Mary-Kate and Ashley Olsen. The Olsens are now active in the fashion world. One episode of Fuller House even joked about their absence. One of her sisters on the show asks where Michelle is. Her father, Danny Tanner, responds: “Oh, she's busy in New York running her fashion empire.”

We all know how it feels to get lost in a great book. But what's happening in our brains as we dive into it? How is it different from what happens as we experience real life? Now, a new study led by Dr Leila Wehbe and Dr Tom Mitehell of Carnegie Mellon University have provided partial answers to these questions. 

Since reading comprehension is a highly complex process, earlier studies tried to break that process down and focus on just one aspect at a time: mapping fMRI signatures（特征）associated with processing a single word or sentence, for example. "It's usually not like reading a book, and usually the stimulus（刺激物）consists of out-of-context sentences designed specifically for the experiment"

To address these issues, the researchers developed a computer program to look for patterns of brain activity that appeared when people read certain words, specific grammatical structures, particular characters" names and other aspects of the story—a total of 195 different "story features". In the study, they first asked eight volunteers to read Chapter 9 of Harry Potter and the Sorcerer's Stone and recorded their brain activity using an fMRI scanner（扫描仪）. Then the researchers fed the volunteers' fMRI data into their computer program and had the program identify the responses of different brain regions to the 195 features mentioned above. 

The result showed that when the volunteers read descriptions of physical movement in the story, there was significantly increased activity in the posterior temporal cortex, the region involved in perceiving real-world movement. Besides dialogue was specifically related with the right temporoparietal junction, a key area involved in imagining others thoughts and goals. "This is truly shocking for us as these regions aren't even considered to be part of the brain's language system," Wehbe says. 

Next, Wehbe and Mitchell hope to study how and why language processing can go wrong. "If we have a large enough amount of data", Wehbe says, "we could find the specific ways in which one brain—for example, the brain of a dyslexic（诵读困难的）person—is performing differently from other brains." And this, the researchers think, may someday help us design individually tailored（特制的）treatments for dyslexia and other reading disorders.

Bruce, a parrot missing part of his beak （喙）,  creatively uses stones to clean feathers （羽毛）,  highlighting advanced intelligence in parrots. 

Bruce lost the upper part of his beak in 2012 and was sent to live at a reserve in New Zealand. The defect made Bruce unable to search for food on his own, let alone keep his feathers clean with his beak. But in 2021, when comparative psychologist Bastos arrived at the reserve with colleagues to study parrots, zookeepers reported something strange：Bruce had seemingly figured out how to select and use small stones to clean his own feathers with his beak. 

Over nine days, the team kept a close eye on Bruce, quickly taking, videos if he started cleaning his feathers. It turned out that Bruce had indeed invented his own way to do so, the researchers reported in Scientific Reports. 

"It's crazy because the behavior was not from the wild, " Bastos says. When Bruce arrived at the reserve, he was too young to learn how to clean his feathers. And no other bird in the reserve uses stones in this way. "It seems like he just invented this tool use for himself, " she says. 

Tool use is just one of parrots' many talents. They're famous for copying and even understanding human speech. Some species can also solve complex puzzles, like how to enter a covered rubbish bin or practice self-control. 

For a concept as abstract （抽象的） as intelligence, it's challenging to develop a definition that applies across animals. Researchers often point to features once thought to make humans special—enhanced learning, memory, attention and movement control—as signs of advanced skills. However, many of these abilities can also be seen in parrots, as well as other animals like chimpanzees, dolphins and elephants. 

"Parrots are our evolutionary （进化的） mirror image. These brilliant birds may teach us about how humanlike intelligence can appear, " behavioral ecologist Antone wrote in his 2022 book The Parrot in the Mirror. With powerful brains and a preference for words, these birds are "the very best example, " he writes,  "of nature's 'other try' at humanlike intelligence. "
