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.

    Old age may not sound exciting.But recent findings offer good news for older people and for people worried about getting older.Researchers found that people become happier and experience less worry after they reach the age of fifty.In fact，they say by the age of eighty­five，people are happier with their life than they were when they were eighteen years old.

    The findings came from a survey of more than three hundred forty thousand adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time，the people were between the ages of eighteen and eighty­five.The researchers asked questions about emotions like happiness，sadness and worry.They also asked about mental or emotional stress.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty­two and twenty­five.The findings showed that stress levels dropped sharply after people reached their fifties.

    The study also showed that men and women have similar feeling patterns as they grow older.However，women at all ages reported more sadness，stress and worry than men.

    Researchers say they do not know why happiness increases as people get older.One theory is that，as people grow older，they grow more thankful for what they have and have better control of their feelings.They also spend less time thinking about bad experiences.

    Professor Stone says the emotional patterns could be linked to changes in how people see the world，or maybe even changes in brain chemistry.

    The researchers also considered possible influences like having young children，being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well­being related to age.

    During his first week as a new Atlanta police officer, Officer Che Milton answered a call for shoplift at the nearby Family Dollar store. When he arrived, Milton found a 12-year-old girl in tears over trying to steal a $2 pair of shoes. Crying, she told Milton that the shoes were supposed to surprise her 5-year-old sister.

    Milton, instead of arresting the girl, asked her to take him to her home instead. When he arrived, Milton's heart sank. He found a house nearly empty, with only a sofa and sheets on the floor instead of beds. There was no food in the kitchen and the kids were there. The girl's mother told the officer that her husband worked but didn't make much money and that she couldn't afford to do the same with several children to take care of and no daycare money to spare.

    Moved, the officer drove to a restaurant and bought four pizzas for them and he called the Division of Family and Children Services and asked if there was a social worker who could help.

    When the police department found out about Milton's trips, instead of punishing him, the department decided to share his story on Facebook and added that “not only is he here to enforce(实施) the law but also to go the extra mile and be a bigger part of the community he is policing.”

    Hundreds of citizens liked the post, asking how they could help. The department followed with posts including the six children's sizes and mother's clothing sizes. It also called for blanket and furniture donations. Visit the posts to learn how you can help and find more useful ways to donate your old things.

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to “watch” TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. “The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves."

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. “This is done in real time, in less than a second, " Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.

    In 2011, Nancy Ballard went for a routine checkup that turned into something extraordinary. In fact, she was carrying a painting of a plant she'd done when she arrived at her doctor's San Francisco office. "It would be great if we had artwork like that for our chemotherapy (化疗) rooms," the nurse said. Ballard asked to see one.

    She was shocked by what she found. The walls were dull and bare, and the paint was chipping (剥落). It was a depressing room for a depressing routine—patients restricted to chemo drips for perhaps several hours, often with nothing to look at other than those sad walls. Ballard didn't have cancer herself, but she could sympathize with the patients. "I couldn't imagine how anyone could even think about getting healthy in a room like that," she says. As it happens, Ballard's physician, Stephen Hufford, was ill with cancer himself, so finding time to decorate the rooms was low on his to-do list. So Ballard made it her mission to brighten up the place.

    She started by e-mailing 20 local designers. "I wrote, 'You don't know me. But my heart hurts after seeing these rooms," she remembers. She then asked whether they would donate their time and money to transform just one of Dr. Hufford's rooms each.

    As it happened, six of them wrote back almost immediately. Six rooms got new paint, light fixtures, artwork, and furniture. Dr. Hufford was delighted. "All the patients feel relieved of the pain because of it," he said. He even noted that his own tone of voice was different in the rooms and that he was better able to connect with his patients.

    Ballard was so encouraged by the patients' reactions that she created a nonprofit, Rooms That Rock 4 Chemo, to raise money and decorate more spaces. Since then, she has worked on 20 projects, including one in Pennsylvania. "We were in Philadelphia for a ribbon cutting, and a woman was there on her third battle with cancer," says Ballard. "When she saw what we'd done, she said, 'I'm gonna beat it this time. I thought I wasn't going to, but now I know I'm gonna beat it".

Comparing college entrance exams, there are different needs for admission. The national college entrance examination, or gaokao, is known as the most competitive test for Chinese students. Do students in other countries also need to take a standardized test to get into university?

South Korea holds the College Scholastic Ability Test（CSAT） in November each year. The CSAT plays an important role in the country's education. On test day, bus and subway frequency increases to make sure that students can get to the test sites in time.

Japan is trying to reform its standardized national college entrance exam. In January 2022, Common Test for University Admissions took the place of the National Center Test for University Admissions, which had been adopted since 1990. The new exam aims to put emphasis on the ability of students to discover and solve problems by themselves.

The American College Test（ACT） and Scholastic Assessment Test（SAT） are the two main college entrance exams taken by students in the US. While SAT tests a student's ability to learn, the ACT tests a student's educational development. Both tests normally take place seven times throughout the year. Students can retake the exams for a better score.

In the UK, there's no standardized test for college admission. Instead, each college has their own admission criteria. These criteria often onlyinclude submission of transcripts（成绩单） and participation in an interview. Yet, there are subject-specific exams used by some colleges.
