On Friday, the company debuted (首发) a desktop device that sends sound directly to a listener without the need for headphones or a special receiver. Noveto Systems gave The Associated Press (AP) a chance to test its Sound Beamer 1.0 before its debut. The AP's Louise Dixon writes that listening to the device is like something from a science fiction movie. The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.

Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. However, because the device does not use headphones, it is possible to hear other sounds in the room clearly.

The device uses a 3-D technology that finds and follows the ear position of the listener. It sends ultrasonic (超声的) waves to create sound pockets by the user's ears. Sound can be heard in stereo or 3-D. The 3-D method creates sound on all sides of the listener, the company said.

The demo (样本) version of the device included nature videos of birds on a lake, bees flying and a quiet waterway. Most people trying the technology for the first time just say, "Wow. I really don't believe it. It sounds like a speaker, but no one else can hear it... it's supporting you and you' re in the middle of everything. It's happening around you."

By changing a setting, the sound can follow a listener around when they move their head. It is also possible to move out of the sound beam's path and hear nothing at all.

While the idea of sound beaming is not new, Noveto was the first to launch the technology. Its chief executive officer Christophe Ramstein said a "smaller" version of the device would be put on the market next year.

Roshawn Little is going into her junior year at Eastern, and has been working in this garden for three years now. During the summer, Little gets paid to work Tuesday through Saturday from 9 a. m. until 2 p. m. with City Blossoms, a nonprofit that brings community gardens to schools in urban areas. She believes that working in the garden has taught her to try all sorts of new things, like eating different kinds of vegetables more often. And she's taken those healthy behaviours home with her and her eating habits have encouraged her family to buy more fruits and vegetables.

City Blossoms is one of many groups across the country teaming up with local communities to build school gardens, like the one at Eastern. It works with schools to create learning gardens and trains teachers on how to use them to get students engaged (使参与) and improve academic performance. These gardens are really outdoor classrooms. For example, the gardens can be used for math lessons, like calculating the area of a plant bed or learning the science of how plants grow.

For the students, the experience can be a nutritional eye-opener, which has totally changed their views on where food comes from, and what it takes to produce food. Partner schools have also seen a 12 to 15 percent increase in the number of students passing standardized tests and 94 percent of teachers reported seeing increased engagement from their students, according to an independent evaluation (评价) conducted by PEER Associates.

a practical tool to learn Chinese language and culture

Confucius said: "To educate somebody, you should start with poetry, and finish with music".

I was doing homework with my friend Ollie at his home when he randomly started scribbling (乱画) a fish. But not just any fish. This fish was riding a skateboard and blowing a bubble that said "I'd rather be skating!"I laughed and drew a sea star saying "Quit fooling around and get to work!"

Just then, Ollie's grandma Abuela and her friend Mr. Goldberg came into the kitchen. Mr. Goldberg was in charge of the local animal shelter. Abuela poured their tea and inquired about how things were going at the animal shelter. Mr. Goldberg sighed, shaking his head. He explained that not enough people were adopting pets, resulting in too many animals without homes.

Overhearing the conversation, Ollie offered to adopt some excitedly. But Abuela said that one noisy parrot was plenty for this house.

"Blue isn't noisy," defended Ollie. "He's just musical."

"I'd have a whole farm full of animals if I could," I said. "But my parents say two cats and a hamster (仓鼠) are enough."

Mr. Goldberg said he kept trying to attract people to adopt animals, but found it hard to get people's attention these days. Ollie drew a sad whale, and I wrote the words "Please adopt me" in the shape of a whale spout (喷水). Mr. Goldberg took a look at our drawings and made favorable comments on them, saying that these clever talking animals just might grab people's attention. And he asked us if we were willing to design a poster for his animal shelter, a proposal we happily accepted. We decided to draw some ideas on our own and meet up again the next afternoon.

That night, when I was sitting in the living room brainstorming ideas for the poster, my little brother brought in our hamster, Mr. Nibbles, to give him a little run-around time. He made a hamster playground out of couch pillows and Mr. Nibbles began to run around merrily.

Suddenly, an idea formed in my mind.

We decided to make both Mr. Nibbles and Blue the stars of the poster.

To understand a painting, we're taught to look for color, composition, and light. But how can a painting (appreciate)by someone who's blind? Through touch, the one thing gallery signs tell you not (do). John Olson, a former (photograph)and his team turn paintings into fully textured 3D models.

The tactile(可触知的)paintings work as a way to show art to blind because we don't see with just Our eyes: We see with our brains. Research in the field of neuroplasticity-the brain's adaptability-shows that the visual cortex(大脑皮层)is made active by touch. Blind people recognize shapes with their (exist) senses, in a way similar to that of (sight )people, says Ella Striem-Amit, a Harvard scientist.

Luc Gandarias, who's now thirteen, went blind suddenly age seven. When he felt a 3D version of Leonardo da Vinci's "Mona Lisa" he (notice)her smile right away. "I can actually feel what you see when you look at it," he said.

For Luc, this means (independent). "The feeling of being able to see it to form my opinion is like breaking down another wall as a blind person."

Well, if certain people have their way, it'll go even further. We'll have microchips implanted (植入) into our brains that can interact with the computers by thought alone. It may sound like something from the science fiction, but in many ways, things look quite promising. Thanks to the ability to send and receive information remotely via computers, microchips and other related devices have long been put into brains.

For example, electrodes have been implanted in the brains of epilepsy patients to better record and even predict the abnormal neurological activity. Similarly, deep-brain stimulation, through implanted devices that cause activity in key brain regions, is an established treatment for things like Parkinson's disease, and is even being looked into for illnesses like depression.

However, it's another thing to place such devices in healthy individuals. There are the practical concerns, not least of which is what these chips will be made of. The inside of the brain is a mass of highly reactive chemicals and electrical activity. Implants would need to be inert (静止的) enough to not upset the delicate processes by their presence, but also sensitive enough to read and process the activity around them. Current technology has made impressive progress with this, but if it were to be rolled out to millions of people, we'd need to be 100 per cent certain that it's safe.

How many people will actually want to have technology literally put into their brain? A surprising 60 per cent of Americans say they'd be okay with it, but that's when it's purely theoretical. In reality, the possibility of having strangers stick chips in your brain is likely to prove unattractive, especially for a population where millions get mad at fictional microchips in vaccines (疫苗), and even more are frightened of dentists.

Ultimately, the technology of computer-brain interface (接口) implants is still far away from us.

Regardless of the sport, Cathy's attitude remains the same: Any athlete failing to respect nutrition is one who is failing to fulfill their potential. It's a key part of the training process. It's not just something that you take casually. She advises her athletes to hold nutrition in the same regard as they do their most crucial bit of equipment. "Just as you wouldn't forget to put your shin pads (护腿板) or your boots in your kit bag, don't forget to put in your drinks and your snacks. That informs how well you train, because you can't get out if you haven't put in."

Nutritionists are sometimes unfairly represented as militant (斗志昂扬的) types telling what athletes can and can't eat. But Cathy insists that when to eat is more important than what. "It's about when's the right time to have it in," she says. It's a message that Cathy says can take a while to sink in. "A lot of boxers say, ‘but bananas make you fat, right?', and there's this inherent belief that we mustn't eat those kinds of things. But it's not about what to cut out. It's about making sure that you've got the foundation right for health and performance. It's that one size fits one. It's what works for you. To be an excellent athlete, you really need to be an exceptional eater."

Together the engine and tender measured a little shy of 2 feet — enormous by the toy train standards of the day. Even better, the 746 had a working headlight and smoker, and its tender sang high.

Unfortunately, the amazing 746 also had an amazing price — $50, equal to about $450 today. That was far more than my grandfather could afford. Instead, I had to be content with his little Lionel plastic, which was SIX INCHES shorter than the 746 and had no headlight, no smoker or no sound! But that was the best that my grandfather could give me at that time.

Years passed, and I was in my 30s. Superior sound systems and computer controls dominated toy trains. I never gave a look. My interest in toy trains, I firmly believed, had faded, so did my admiration for the 746, since my grandfather was not with me. The 746 was never called to mind. On an ordinary day, however, I happened to see the 746 outside the window of a train show. Just one-look, I could not look away. Childhood memories that I tried to hide in the depths of my heart raced through my mind, happy or sad.

That day I took the 746 home and placed it in the center of the room, and let my childhood dream sing its way around me. Smoke rose out from the engine and the soft song sounded from its tender. It seemed as if I could see the soft light in grandfather's eyes and hear his cheerful laughter.

Sometimes things don't go as planned, but that doesn't mean they can't still be wonderful in their own way. My parents and I had spent forever researching summer camps online. Finally, we picked out one where I could design games, animate (制作动画) characters, and learn other cool coding (编程) stuff.

My mom said, "I like the idea of you exercising that clever brain of yours. But I also want you to get plenty of fresh air." "Campers can choose to hike or swim every afternoon!" I said, as I clicked on the registration form.

My dad filled out the form, and weeks later, my parents dropped me off for what I thought would be a week of nonstop computer-coding fun.

I arrived at the check-in table at the same time as a camper of my age named Halley, who was wearing an adorable sunhat. Halley greeted, "We are in the same group - number 7." Led by an advisor, we followed the green arrows to the campsite.

I surprisedly found that it was so cool and woodsy along the path. I exchanged ideas with Halley about what might come out of the camp. Halley excitedly mentioned the little animals he loved to observe and something about night sky watching.

"You gave me the best idea," I said. "I'll base my characters on the animals you mentioned!" Halley laughed. "I might be missing something here. Who are these mysterious characters?"

"You know, the characters we'll be designing and animating on computers this week!" I said. "Uh, sorry. Still lost," said Halley. "Why would we be doing computer stuff at Nature Camp?"

It was then that I realised some errors must have been made. I must have accidentally clicked on the wrong online form! We immediately raced back to the welcome table to see if I could switch over to Tech Camp, but of course it was completely full.

3, I was unharmed and stepped out to4 the situation. The girl who had hit me was in tears. She5 to me and explained that her brakes (刹车) had taken longer to6 because of the slippery road. Minutes later, a policeman7 and directly issued the girl a ticket for "failure to control speed", and several other offenses, which could have led to the8 of her license. The girl was extremely upset, but she was helpless against the result. I comforted her that it wasn't her9 and promised to help.

Two weeks later, I received a notice to appear as a witness in the girl's trial. Although it wasn't required, I decided to seek10. Upon seeing me in court, the girl appeared quite11. I recounted the incident12, saying neither of us was speeding and that the road was exceptionally slippery. I also13 the girl wasn't to blame.

When I finished speaking, the courtroom erupted into applause, and the judge praised me for14 my citizen's duty. After careful consideration, he dismissed the15 against the girl. I believe whoever encounters such a case would do the same.

She credits these skills to her late grandfather and builder Derek Lloyd. From the age of six, Terri, now 26, accompanied Derek to work during her school holidays. A day's work was rewarded with £5 in pocket money. She says: "I'm sure I wasn't much of a help to start with, painting the rooms and putting down the flooring throughout the house. It took weeks and it was backbreaking work, but I know he was proud of my skills."

Terri, who now rents a house with friends in Wandsworth, South West London, says DIY also saves her from losing any deposit when a tenancy (租期) comes to an end. She adds: "I've moved house many times and I always like to personalise my room and put up pictures, so, it's been useful to know how to cover up holes and repaint a room to avoid any charges when I've moved out."

With millions of people likely to take on DIY projects over that coming weeks, new research shows that more than half of people are planning to make the most of the long, warm summer days to get jobs done. The average spend per project will be around £823. Two thirds of people aim to improve their comfort while at home. Two fifths wish to increase the value of their house. Though DIY has traditionally been seen as a male hobby, the research shows it is women now leading the charge.

Silent walking involves walking outdoors without distractions like music or conversations, focusing on the mind-body-nature connection. That's a slower, lower-impact way to relax and is great for fitness. Here's everything you need to know about the trend.

Select a natural setting and fully engage your senses. For reaping the mental health benefits, it is recommended to find a quiet and peaceful natural location. Meanwhile, consciously observing the sights, sounds, smells, and physical sensations during the walk can significantly impact cognitive and emotional well-being.

To stimulate the mind, consider exploring different routes than usual. Without your favourite podcast or playlist, you might slip into boredom on your walk. And it might even be good for your brain. Scientists applaud the virtues of boredom for brain health, believing that it boosts creativity and improves social connections. And if you do get bored, rest assured that it shows you've disconnected from external distractions. Go with it, and make sure you take a different route each time — it'll keep you motivated.

Start off with five-minute silent walks and eventually build up to thirty minutes. If you're usually a headphone wearer, it will feel super weird to walk without your go-to tunes, but give yourself a second to adjust. Chances are, once you're a few minutes into your silent walk, you'll feel the magic kick in.

Regular reflection and ongoing documentation are essential. After completing a silent walk, take time to reflect upon any emerging thoughts, feelings, or insights. Journaling about the experience can also solidify connections between thoughts and ideas, providing a valuable tool for self-reflection and growth.

A. But being bored won't hurt you.

B. Taking different paths can lead to exciting discoveries.

C. Adjusting the routine gradually can help ease into the experience.

D. You'll also start noticing the little things around you more clearly.

E. They can deepen understanding and serve as a record of personal growth

F. Unlike exercise-oriented walking, it isn't about reaching certain speed or steps

G. In such an environment, you can immerse yourself in the natural soundscape (音景) .

I taught English as a Second Language (ESL) at a school. One particular sixth grader, Pablo, was struggling with fluency in reading, so after class I suggested that he get extra practice by reading aloud to his mom while she prepared dinner each evening. This was something I routinely encouraged my struggling students to do. Imagine my surprise when Pablo responded by starting to cry. He said, "My mom can't cook dinner!" Then he cried harder. Eventually, he calmed down enough to tell me that his mom was only able to "cry in her bed" when he got home every afternoon. He said that he was caring for his six-month-old baby brother by himself from the time he got home each day. His mother, it seemed, had a bad tooth and was in extreme pain. He said that his father didn't have enough money to get it fixed, and that there was no way for her to go to a dentist. This child's heart was broken for his mom.

I was speechless! He was still crying when he left me that day, and I promised him I would try to help. I kept asking myself how I could help this student. How could I help his mother when we didn't even speak the same language?

The next day, I sent a note, which a friend helped me translate, to Pablo's mother asking if she would like me to find someone to help her. The following day, Pablo brought me a note from his mom accepting my offer to help.

Meanwhile, I had been doing some networking among my friends asking if anyone knew a dentist who might do some free work for this lady. At the time, I was not able to pay for the work to be done myself. Several friends suggested a dental office that had recently opened up in the area, thinking that they might be willing to provide the services. I didn't want to waste a lot of time going to several dentists, so I prayed that this would be the one.

China's first artificially-bred(人工繁殖) second-generation finless porpoise (江豚) is named Hanbao. The name's meaning is dividedtwo parts: "han" means it was born in Wuhan, Hubei province, "bao" means little baby in Chinese. As the fattest porpoise at a local Baiji dolphin museum in Wuhan, Hanbao(weigh) about 70 kilograms.

Finless porpoises, also called "smiling angels", have become sign of the health of the Yangtze River ecosystem. To prevent their extinction, finless porpoises have been bred artificially. Despite efforts to protect the finless porpoise for over 40 years,(it) numbers continued to fall. However, a scientific survey of Yangtze finless porpoises(carry) out on Oct 25 indicated the species' recovery. The change is owed to a 10-year fishing ban on the Yangtze River, began on Jan 1, 2021 and the Yangtze River Protection Law that came into effect two months later.

Because of these measures,(region) along the Yangtze River have relocated their chemical plants, restored wetlands and reorganized the sailing route. All these efforts(ultimate) improved the river's ecological environment,(help) to breathe life into the finless porpoise species.

That's why I decided to have a3 — hiking from Kazbegi Town to Gergeti Trinity Church. Though the trip is a short one, based on the church's location atop a mountain, I knew it was going to be a4 climb — especially after six weeks of traveling around.

In 2005, a terrible hurricane hit Kane's hometown. After it, she had to cope with the loss of her home. In watching the cardinals and other birds, she found relief. Soon she started bringing her students along. "My students stared at me in disbelief when I told them I had never cared about birds before," Kane writes. "I suddenly wondered how many creatures would die because of the way we lived." She decided to pursue an environmentally-conscious career. In 2007, she took a course to study environmental science.

Most of the book focuses on Kane's efforts to preserve Warner Park, an ideal location satisfying birding requirements for her class. She successfully campaigned to stop the construction of a parking lot. Her activism snowballed into a local bird watching and protecting organization. It eventually became part of Kane's doctoral research, and launched a birding class that pairs middle school students with college-student advisors.

The book shows readers that a good knowledge of nature doesn't require a degree. Take Jeremy, a seemingly uninterested boy in Kane's birding class. When reporters joined an outing, the normally quiet Jeremy started talking excitedly about the bunting, a small blue bird. Kane soon learned that he had secretly taken to studying the field guide given to him by his advisor.

At its core, Birding to Change the World is about how people and birds today depend on one another. "For birds, that dependence is concrete. For thousands of years, our species has seen birds as a symbol of liberation," Kane writes. In her case, it is liberation from the grief and depression that the hurricane brought. "Bird by bird, they carve a new pathway in my life, a joyful pathway."

During a match in May, Wu Chuguo, a decoration worker from Liubaitang village, Rongjiang County, scored a spectacular 40-meter goal that ignited (点燃) the crowd. Wu said he was influenced by elders in his village and fell in love with the sport. In the county, rural soccer matches have taken place regularly since the 1990s. When there was a lack of facilities, soccer players used barren land as a field and wooden stakes for the posts. The boundaries were marked out with lime powder. When they couldn't gather enough players, they played futsal, a soccer-based game played on a smaller hard court.

In recent years, the county has focused on gymnastics, soccer, rock climbing and other sports. What sets the Village Super League apart from other sports events are the vivid displays of ethnic cultures and traditions at the tournament. As players of both teams walk on the field for a game, they are accompanied by their cheering squads (啦啦队) dressed in traditional ethnic costumes and carrying local specialties. The halftime break features folk songs and dance performances, while ethnic costumes are also on display.

"hope that more and more tourists will come to Rongjiang to watch the matches, enjoy the folk customs and local cuisine, and have fun," said Xiong Zhuqing, a melon grower who is also a cheerleader. She says she has sold over 10,000 kilograms of watermelons since the start of the tournament. As of June 27, a total of 654 new businesses were established, including 91 in the catering sector, 188 in retail, and 195 in agriculture and food processing, the local government said.
