Japan's youth are losing interest in science and as a result, threatening the nation's industrial progress. According to Japan Science and Technology Agency, young Japanese are surrounded by high-tech devices(设备), but are not interested in how they work.

    Japanese businesses have succeeded partly because they've a great many engineers. A drop in interest could lead to a decline(减少) in their numbers and quality. "In the past, the young had a big interest in science and technology," said Hirano, director of the agency's policy department.

    There are two main reasons for the problem. The first is known as "black box syndrome" of modern technology.

    Electronic devices depend on tiny silicon chips（芯片）, which can only be made in big factories, whose workings can't be seen by the eyes. The devices, unlike machines of the past driven by gears and wheels, are simply boxes.

    Young Japanese, brought up on video games and at home with computers, enjoy using modern technology, but this is a passive interest and different from the interest in how things work. "You need an active interest to get interested in science. This is declining in the young," said Hirano.

    About two-thirds of Japanese in their 20s use PCs, twice the number of those in their 50s. But only 40% of those in their 20s say they are interested in news about science and technology, compared to 60% of the 50 to 60 year olds.

    "Another reason for it is that life in modern Japan is too comfortable," he said. "A wealthy society reduces people's desire to modernize and develop their country. To a degree, you can't avoid this when the fruits of science and technology are fully developed." Similarly, science in Europe and the US has also suffered a lack of interest.

    The Asian country announced yesterday that China was putting tariffs or taxes on about $3 billion worth of imports from the U.S. The tariffs are on 128 American-made products, ranging from pork and fruit to steel pipes. This will make it more expensive for America businesses to sell those products in China. And China says this was done as a response to the tariffs that the U.S. recently put on imports of Chinese steel and aluminum.

    Meanwhile, U.S. President Donald Trump says more tariffs, new ones worth as much a $50 billion are being planned by the U.S. on additional goods from China. So, one big question is, will all this cause a trade war, when countries take turns putting tariffs on each other 's goods, causing prices to rise?

    We don't know yet. The U.S. and China ship hundreds of billions of dollars of goods back and forth every year. So, the tariffs we've seen so far are a tiny part of that. And America's treasury secretary says the U.S. and China are talking behind the scenes about how to prevent a possible trade war.

    But a number of experts are concerned this could turn into one and so are some stock investors. The Chinese tariffs were a major factor in a drop of the U.S. stock market yesterday when the Dow Jones Industrial Average fell 459 points. But just like it's hard to tell if a trade war is on the horizon, it's also hard to tell what kind of effects one could have decades down the road.

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."

    University of Pennsylvania researchers say that for the first time they have linked social media use to increases in depression and loneliness. The idea that social media is anything but social when it comes to mental health has been talked about for years, but not many studies have managed to actually link the two. To do that, Penn researchers, led by psychologist Melissa Hunt, designed a study that focused on WeChat, Snapchat and Instagram.

    The study was conducted with 143 participants, who before they began, completed a mood survey and sent along photos of their battery screens, showing how often they were using their phones to access social media. "we set out to do a study which attempts to imitate real life." Hunt said.

    The study divided the participants into two groups: The first group was allowed to maintain their normal social media habits. The other, the control group, was restricted to 10 minutes per day on social media. The restrictions were put in place for three weeks and then tested for now comes such as fear of missing out, anxiety, depression and loneliness.

    The results showed a very clear link between social media use and increased levels of depression and loneliness." Using less social media then you normally do would lead to significant decreases in both depression and loneliness " Hunt said.

    Social media invites what Hunt calls "downward social comparison." "When you're online, it can sometimes seem that everyone else is cooler and having more fun and included in more things and you're left out," Hunt said. And that's just generally discouraging. "Every minute you spend online is a minute you are not doing your work or not meeting a friend for dinner or having a deep conversation with your roommate." And these real life activities are the ones that you can encourage self-esteem and self-worth, Hunt added.

    "People are on their devices, and that's not going to change," she said. But as in life, a bit of control goes a long way.

I'd say I quarrel with my parents a lot.Throughout high school,I was always jealous(羡慕的) of some of my friends who didn't seem to have those problems at home,but I've come to see over the years that no one's situation is perfect.

Part of the reason I work all week during my break,in addition to the money,of course,is to be out of the house to avoid continuing quarrels.At work,I eat lunch with my friend Krysta every day,but the best days are when our favourite workmate,Lucy,is on her lunch break at the same time as us.Her funny way of storytelling always has us laughing happily,and although she is almost old enough to be our mom,she feels more like a best friend.

A few weeks ago,however,there was a change in our lunch conversation,and the story she told had us in real tears instead of our usual tears of laughter.A more serious topic had come up,and she sat us down to explain the importance of forgiveness(宽恕),especially when it came to our parents.Telling stories of her troubled relationship with her mother,she changed my whole outlook on life and my feelings towards my parents.She reminded(提醒) us that no matter how much resentment(怨恨) we're feeling in a moment of anger,we have to be thankful for the support they provide and learn to forgive everything else.

This week I've spent my break at home,having very small quarrels and lots of quality time together with my parents.Sometimes you need a reminder to make you realize how important it is to let go of past resentment and work to repair broken relationships.My workmate's moving stories not only brought me to tears in the break room at work that day but served as that wake-up call as well.

Max Du emerged victorious at the Canada-Wide Science Fair with his innovative project: an unmanned aerial vehicle (UAV) designed to assist individuals experiencing cardiac arrests. His ingenuity was sparked during the Christmas recess of the preceding year. "I received a recreational drone as a gift from my parents, yet I was unable to operate it aloft due to the snowy conditions," Max recounted. "Consequently, I experimented with it indoors, which led me to contemplate the potential for a drone to serve as an automated indoor apparatus that could render assistance to people in need."

Approximately 35,000 Canadians succumb to cardiac arrests annually, with the majority of these incidents occurring beyond the confines of a hospital, resulting in a survival rate of less than 10 percent. Max was convinced that a drone could provide more expeditious assistance and expedite the delivery of vital medical treatments, but to validate this hypothesis, he was compelled to construct the device himself.

The process of refining his drone spanned a period of six months, during which Max's parents had to tolerate the persistent buzzing and crashing of the machine within their domicile. With each innovative feature he devised, such as a telescopic appendage, the drone's overall mass increased, leading to frequent disassembly. This necessitated the procurement of an entirely new set of components. Max persevered, experimenting with more lightweight construction materials until he achieved a more harmonious equilibrium in his design.

Through a methodical process of iterative refinement, the 14-year-old prodigy ultimately perfected his invention. His drone is now capable of manipulating a door handle, navigating through the air, and alighting gently on the ground. An innovative, extendable arm can be deployed to either administer an injection or deliver a life-saving pharmaceutical to a patient. Additionally, an integrated camera facilitates real-time communication with an emergency response team, enabling remote monitoring of the patient's condition.

Max is intent on pursuing the acquisition of a patent to forge alliances within the healthcare sector and bring his invention to fruition. He dedicated his summer to the study of artificial intelligence at Stanford University in California, where he was one of only 32 young scholars chosen globally. Subsequently, he will proceed to the University of Pennsylvania to enroll in a collegiate-level robotics course before resuming his high school studies in September.
