We have heard some interesting ways that 5G wireless technology might change our lives in the future.
5G short for the 5th generation mobile communication technology, promises Internet speeds between 50 to 100 times faster than current 4G systems. While 5G is set to be used in some limited areas of America this year, much of the world is not expected to receive widely available service until 2023.
One project in Britain, however, is already testing this super fast technology on an unlikely group of Internet users—cows. The project was developed by American technology company Cisco Systems. It also receives money from the British government. Cisco says the program seeks to explore the future of 5G connectivity in rural areas around the world.
Testing areas were set up at farms in three rural areas of England. The cows are equipped with 5G-connected devices (装置) that link up to a robotic milking system, which uses sensors (传感器) and machine learning to fully automate the process. System designers say technology takes over after a cow feels ready to be milked and walks toward an automatic gate. The device is designed to recognize each individual cow. It then positions equipment to the right body position for milking. During the process, machines release food for the cow as a reward.
Other 5G technology tools include automated brushes that turn on when the cow rubs up against them. Sensors also control the amount of light to the cows’ living areas depending on the weather. And an automatic feeding system makes sure the animals always get enough to eat.
Duncan Forbes, head of the project, told Reuters that the project shows the farm’s cow operations can be greatly improved with 5G technology and that the experiment provides strong evidence that 5G technology can be widely used in the future, not just on farms in Britain, but in rural communities across the world.

【推荐1】Morten Petersen used to live in a windowless basement flat in Copenhagen. If he didn't get out in the daytime, he would lose track of time and start becoming annoyed and depressed. "When you are living in a basement with only artificial light, it becomes very clear that something is lacking,’’ he says. “It's an emotional,physical and mental thing all combined. ”
You can say that again. Our lifestyles have rapidly changed with light. Prior to the invention of gas lighting at the turn of the 19th century, the only artificial light we could rely on was from flickering firelight, candles or whale-oil lamps. People also spent many more of their waking hours outside. Over time,the technology of artificial light has been advancing,thus changing the way people live and work.
Today, the average westerner spends 90 per cent of their life indoors. That means we are getting less light during the day and being exposed to more light at night. This pattern is increasingly being linked to disturbed sleep and circadian rhythms — 24-hour changes in our biology and behavior — with consequences for our physical and mental health. Meanwhile, getting too little sunlight is contributing to vitamin D shortage and may be weakening our immune and cardiovascular systems as well.
Our changed relationship with the sun is greatly affecting our biology .That's why people like Petersen are being taken in by researchers to help investigate how much damage we do by shying away from the light, and just how much light we need. The good news is that researchers are finding even small increases in your exposure to bright light will bring about great changes to your health.

【推荐2】If there was an app claiming to improve your memory, would you be willing to try it? It’s hard to resist the idea of having a better memory.
In response to this perceived need, the brain training industry has grown rapidly, offering a wide range of accessible and affordable mental exercises through smartphone and tablet apps. Many researchers have found evidence suggesting that well-designed exercises can improve mental abilities and lead to better scores on IQ tests. They compare the brain to muscles, suggesting that targeted repetition of memory exercises can strengthen and condition our memory processes, similar to how athletes engage in strength and conditioning by repeatedly exercising specific muscle groups.
In contrast to everyday activities like solving a complex puzzle, memory training apps are specifically designed to provide a more challenging workout for the brain. These apps typically involve tasks that require tracking a large number of objects while being distracted (使分心) by a secondary task, such as mental calculations or exploring a game’s landscape. If this brain training proves effective, it could be beneficial for individuals with brain-related disabilities or those recovering from conditions like cancer.
Critics, though, argue that while the concept is appealing, the overall evidence fails to demonstrate significant improvement in core brain processes. Additionally, despite the claims made by many apps and brain training companies, scientists have yet to identify the key factors that make an intervention truly effective or determine the best approaches to address the diverse needs of individuals seeking help.
While the question is still open to debate, there is evidence suggesting that short-term working memory training can benefit high-functioning individuals. However, it’s important to note that brain training, like diet and exercise, is unlikely to have identical effects on every individual.

【推荐3】A study published in the journal Frontiers in Psychology took a closer look at music in sports, specifically how listening to music could affect one’s overall performance.
Researchers asked 150 volunteers to throw a ball into a basket. For the first stage of the study, participants threw the ball from a fixed point. They threw the ball while listening to music of their choice, while not listening to music, or while listening to music that the researchers selected. For the second stage they were able to choose where to stand when throwing the ball and performed the same activity with the various music choices.
The study found that listening to music, whether it was music of the volunteer’s choice or a song chosen for them, did not make the participants more or less likely to get the ball in the basket. It had no effect. What it did do was increase self-esteem and make the study participants more likely to take risks, especially for males who were allowed to choose their own music.
The results suggest that music may pump you up. And it may even help you work out harder and longer than you would without it. But no matter what song you listen to, it’s not going to help you get that ball into the basket.
Another study took a detailed look at how music pace might affect exercise. Researchers found that listening to high-pace music makes people feel like they’re working out less while also benefiting their bodies more.
Listening to high-pace music while exercising resulted in the highest heart rate compared with not listening to music. This means that the exercise seemed like less effort, but it was more beneficial in terms of enhancing physical fitness.
The study found that the beneficial effects of high-pace music were greatest for people who were walking or running and were felt the least for those who were doing high-intensity exercises such as weightlifting.

【推荐1】The world’s first zero-carbon city is being built in Abu Dhabi and is designed to be not only free of cars and high buildings but also powered by the sun.
The oil-rich United Arab Emirates (UAE) is the last place you would expect to learn lessons on low-carbon living, but the eco-city of Masdar could teach the world. While the presence of fossil fuel (矿物燃料) has helped make UAE one of the world’s wealthiest countries, the officials there are well aware that the oil wells will eventually run dry, leaving them with no choice, but to use renewable sources of energy.
Masdar is combining 21st-century engineering with traditional desert architecture to create zero-carbon comfort. It will house about 50,000 people, at least 1,000 businesses and a university. It is being designed by the British architectural firm Foster + Partners. The architects are turning the desert’s greatest threat-the sun-into their greatest fortune. They have built the biggest solar farm in the Middle East to power the city.
Traditional cars must be checked in at the city gates before you enter the city. And you can choose between the oldest and newest ways of transport. At street level, the streets will be narrow, just to let people walk by and so the buildings will shade each other, and the planners have done their best to keep the city foot-friendly. But if you feel tired, you can go down a level to take mini vehicles. These driverless vehicles can carry up to 6 people and will be solar powered or battery operated. They are programmed to go where you ask.
Water that is used in homes or for gardens will be recycled. All waste will be converted to energy or as nutrients for soil. The whole purpose of Masdar City is to reuse or recycle everything that is in it even some of the construction materials around gardens and city.

【推荐2】A recent report from the United Nations group UNESCO warns that using technology in classes may not help as much as many people believe. The report suggests that technology should be used less in schools, and that smartphones should be banned from classrooms.
The goal of the new report was to improve how technology is used in education. It says that technology can be helpful, but it shouldn’t be the focus. “Too much attention on technology in education usually comes at a high cost,” the report says.
These days, it’s common for students to use computers or tablets (平板电脑). In many places, it’s normal for students to look up information on the internet rather than using books. UNESCO claims that technology changes so fast that it’s hard to study how it really affects students.
The new report says that many of the studies show that technology helps students come from rich countries. As classes moved online during the Covid-19 pandemic, the use of technology in education grew even more quickly. Many students were forced to study at home, using video calls to communicate with their teachers. But the report points out that around 500 million students were unable to take part in online classes. That’s one example of what UNESCO says is a larger problem — that the advantages of technology aren’t evenly shared. People and countries with less money are often left out.
UNESCO admits that technology can help in many ways. It can allow students to learn in ways that are more interesting; it can also help teachers explain difficult ideas; it can also help students who have special needs. But UNESCO says technology can also be very perturbing. One study showed that when students use phones in class, it can interfere with their learning. Even so, less than 25% of the world’s countries ban phones in schools.
The report suggests that the best way to learn is still to work closely with teachers. Working with other classmates also helps students learn. UNESCO says that most schools should spend more money on things like books, classrooms, and teachers.

【推荐3】Working robots are typically big, simple and strong. They are large preprogrammed units working in dangerous jobs. But the idea of putting “cobots” which work in harmony with humans into use has become a reality and has changed robotic products worldwide.
Cobots include robots made of tough materials that provide support for the disabled and software-based assistants for home of online services. With their operating software updated from the Internet,these helpers will become an extension of mobile devices.
Most industrial robots are not designed to deal with unpredictable human jobs. However, by reducing robots down to desktop size and planting them with AI, the next generation of cobots will learn from us and cooperate with us better. Lightweight cobots can work in less space and share themselves with people rather than being caged off. Decreasing costs for robotic systems make them more suitable for small businesses, and their easy set-up makes them simple to deploy. Typical industrial uses for cobots include packing and machine tending. More detailed uses include cleaning dirty samples, picking plants, making tea and coffee and so on.
Still, experts thought that introducing robots would lead to job losses. Some people said that 20 million industrial jobs would be lost worldwide by 2030.Actually,it was not the case. What big companies such as Germany’s Mercedes-Benz discovered was that robots alone were not intelligent enough to keep pace with the demand for special products, which still depends on a large number of skilled staff to control and push the whole progress.
“Unplanned changes to production and safer interaction with humans will then require a step change in robot improvements. It has become necessary to use the new generation of cobots in people’s daily life, and cooperation should be considered as an applicable strategy. When we make people and machines cooperate, we can produce many more products on one production line,” said Markus Schaefer, head of production planning.

【推荐2】For many years, no one could communicate with people who had been born without hearing. These deaf people were not able to use a spoken language.
But, beginning in the 1700s, the deaf were taught a special language. Using this language, they could share thoughts and ideas with others. The language they used was a language without sound. It was a sign language.
How did this sign language work? The deaf were taught to make certain movements using their hands, faces, and bodies. These movements stood for things and ideas. People might move their forefingers across their lips. This meant, “You are not telling the truth.” They might tap their chins with three fingers. This meant “my uncle.”
The deaf were also taught to use a finger alphabet. They used their fingers to make the letters of the alphabet. In this way, they spelled out words. Some deaf people could spell out words at a speed of 130 words per minute.
Sign language and finger spelling are not used as much as they once were. Today, the deaf are taught to understand others by watching their lips. They are also taught how to speak.

The Double Ninth Festival is a special day for elderly people in China. The festival is on the ninth day of the ninth month of the lunar calendar. As the Chinese word for nine has the same sound as the word for long, people take the Double Ninth Festival to show their wishes of long life for elderly people. This year it falls on Oct. 23.
There are many traditions for this festival. On that day, families get together and climb mountains for luck and in the hope that elderly people will live much longer. They also drink chrysanthemum wine (菊花酒) and wear a plant called zhuyu to celebrate it. Both chrysanthemum and zhuyu are regarded as clean plants that can clean houses and cure diseases.
Respecting elderly people is shown not only on this special day but also in daily life. For example, when an older person enters a room, everyone stands up. When there are several guests at the table, the host usually introduces them from the oldest to the youngest. When a younger person is presenting something to an older person, two hands are used. On a crowded subway or bus, younger people always offer their seats to elderly people.
It is a traditional virtue (美德) in China to respect elderly people. That’s because the Chinese know that elderly people have knowledge and experience that young people can learn from. So, Chinese people are proud of being old. Besides, to respect the elderly people is to respect yourself tomorrow.
