The Americans believe that anybody can become president of the United States. In a recent Hollywood comedy, that is exactly what happens.

    Dave Kovic, played by Kevin Kline, is a kind-hearted man who runs a business that finds people jobs. He leads a typical American way of life, except for one thing－he looks exactly like the president, Bill Mitchell. In fact, the only thing that makes him different from the nation's leader is that he is very nice!

    The president has started using look-alikes during some public appearances. Dave is offered a chance to “serve his country” by becoming one. However, things go wrong. The president becomes very ill and Dave ends up acting as the president forever.

    Director Ivan Reitman, who made the popular and successful comedies like Twins, Ghostbusters and Legal Eagles, could have gone for easy laughs by making fun of the American government. Instead, Dave is an attractive comedy about an ordinary man in extraordinary situations. Kevin Kline gives a double performance as Dave and the president, and Sigourney Weaver is at her best as his First Lady. The love story that develops between her role and Dave is a real classic.

    The film is 100% American. However, if you've ever felt that anybody could do a better job running the country than the people in power, then you'll enjoy Dave!

    Summer heat can be dangerous, and heat leads to tragedy far too often. According to kidsandcars, org, an average of 37 young children per year die of car heat in the US, when they are accidentally left in a hot vehicle.

    For Bishop Curry, a fifth grader from McKinney, Texas, one such incident hit close to home. A six-month-old baby from his neighborhood died after hours in a hot car. After hearing about her death, Curry decided that something needed to be done. Young Curry, who turned 11 this year, has always had a knack for inventing things, and he drew up a sketch(草图) of a device he called "Oasis."

    The device would attach to car seats and watch the temperature inside the car. If it reached a certain temperature in the car, and the device sensed a child in the car seat, it would begin to circulate cool air. Curry also designs the device using GPS and Wi-Fi technology, which would alarm the child's parents and, if there was no response from them, the police.

    Curry's father believes that the invention has potential. "The cool thing about Bishop's thinking is none of this technology is new," he said. "We feel like the way he's thinking and combining all these technologies will get to production faster." His father even introduced the device to Toyota, where he works as an engineer. The company was so impressed that they sent Curry and his father to a car safety conference in Michigan.

    In January, Curry's father launched a campaign for the invention. They hope to raise money to finalize the patent, build models, and find a manufacturer. Their goal was $20,000, but so many people believed in Oasis' potential that they have raised more than twice that--over $46,000.

    Curry's father remembers the first time he saw his son's sketch. "I was so proud of him for thinking of a solution," he said. "We always just complain about things and rarely offer solutions."

    A new restaurant in Indonesia is on a mission (使命) to support locals trapped in poverty, many of whom are earning less than $25 a month, by providing them with an alternative way to pay for their food.

    The Methane Gas Canteen, run by husband and wife team Sarimin and Suyatmi, is located in an unexpected place for an eatery — Jatibarang Landfill. The landfill is a mountain of purifying waste, where poor locals spend their days collecting plastic and glass to sell. Meanwhile, the couple, who spent 40 years collecting waste before opening the restaurant, is busy cooking.

    What makes the restaurant unusual, aside from its location, is that no cash is required to pay for meals. Poor people have the option to pay for their food with recyclable waste instead of cash. Sarimin weighs the plastic customers bring in, calculates its worth, and then deduct that value from the cost of the meal, giving any extra value back to the customer. The scheme is part of the community's solution to reduce waste in the landfill and recycle non-degradable plastics.

    “I think we recycle 1 tonne of plastic waste a day, which is a lot. This way, the plastic waste doesn't pile up, drift down the river and cause flooding,” said Saimin. “It benefits everyone.”

    The restaurant seats about 30 people and serves meals that cost between $0.40 and $0.80 each. Since opening the canteen Sarimin and Suyatmi have seen their daily income more than double to $15 a day.

    “I'm happy to see our customers enjoying their meals,” Sarimin told NHK World. “The poor must also have the right to enjoy healthy eating. I want to give them that chance as much as possible.”

    Britain faces social problems as lots of people are set to lose their jobs in technological revolution, Bank of England's chief economist warned.

    Andy Haldane said the so-called Fourth Industrial Revolution will make the machine replace humans to do thinking things. The dark side of the change could be a much bigger breakdown of employment than in Victorian times, with professions such as accountancy (会计) among those at risk.

    A report by the accountancy firm PwC last month warned that more than 7 million jobs in Britain had been lost over the next 20 years as technological change sweeps though workplaces.

    The majority of these are in jobs in the retail, transport and manufacturing industries. However, other traditional professional sectors could also be at serious risk.

    Economists treat the arrival of increasingly intelligent computers and robots as the fourth industrial revolution. The first was the shift from agricultural to urban societies, the second saw the widespread use of electricity and steel, and the third was the digital revolution when computers, the Internet and mobile phones were developed.

    Mr. Haldane said the hollowing-out (空洞化) experienced in the past years could be on a greater scale in the future so it is important to learn the lessons of history and ensure that people are given training to take advantage of new opportunities.

    “Jobs were effectively taken by machines of various types, there was a hollowing-out of the jobs market, which left many people for a long period out of work and struggling to make a living,” Haldane added, “That heightened social and financial tensions, and led to a rise in inequality. This is the dark side of technological revolution.”

    “That hollowing-out is going to be potentially on a much greater scale in the future, when we have machines thinking and doing the cognitive and technical skills of humans.” Mr. Haldane said professions like accountancy could be among those hardest hit by the rise of AI. But he suggested economists could escape.

    The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is vital to the formation of complex societies. So is the face's ability to send emotional signals, whether through an unconscious red face or the artifice of a false smile. People spend much of their waking lives reading faces, for signs of attraction, hatred, trust and fraud. They also spend plenty of time trying to hide true feelings or intentions.

    Technology is rapidly catching up with the human ability to read faces. In America facial recognition is used by churches to track worshippers' attendance; in Britain, by retailers to spot past shoplifters. In China, it confirms the identities of ride-hailing drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple's new iPhone is expected to use it to unlock the home screen.

    Set against human skills, such applications might seem incremental(增值的). Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode(编码)them. Although faces are unique to individuals, they are also public, so technology does not, at first sight, interfere with something that is private. And yet the ability to record, store and analyze images of faces cheaply, quickly and on a vast scale promises one day to bring about fundamental changes to opinions of privacy, fairness and trust.

    Start with privacy. One big difference between faces and other biometric data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. Facebook's bank of facial images cannot be used by others, but the Silicon Valley giant could obtain pictures of visitors to a car showroom, say, and later use facial recognition to serve them ads for cars. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens' privacy.

    The face is not just a name-tag. It displays a lot of other information—and machines can read that, too. Again, that promises benefits. Some firms are analyzing faces to provide automated diagnoses of rare genetic conditions, far earlier than would otherwise be possible. Systems that measure emotion may give autistic(孤独症的)people a grasp of social signals they find difficult.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be the so–called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too. The researchers added, "Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start."

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, "This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful."
