China’s new bullet train is now the world’s fastest land vehicle (交通工具) China Rail-way Rolling Stock Corporation showed the production version of its magnetic levitation (磁悬浮) bullet train in Qingdao on Tuesday. State media says the train has a top speed of 373 mph. That speed doesn’t just make it the fastest train in the world, but makes it the fastest land vehicle. The bullet train is able to travel at such high speeds because of magnetic levitation. The technology uses electro-magnetic force to levitate the body of the vehicle less than two inches from the rails and drive it forward along the tracks. By riding on a cushion of air, friction (摩擦力) is completely reduced, allowing it to travel faster than traditional trains where wheels and rails are constantly in contact. Although China has made use of the technology for a couple decades now, it’s only ever been used at very limited areas.
China Railway says its bullet train will greatly help cut down travel time. At top speedy the vehicle will be able to complete the 754-mile trip between Beijing and Shanghai in just two and a half hours. That same trip takes just over three hours by plane, five and a half hours by current high-speed rail options or 12 hours by car. That could make the train an especially attractive travel option for business travelers in the country. It’s unclear when the new bullet train will go into operation. The vehicle that the company showed off on Tuesday is the finished article.
Of course, the train’s record might not stand for long. The Central Japan Railway Company is testing a maglev train. It will be able to top out at 375 mph, according to New Atlas. But that isn’t expected to be shown in public until 2027 at the earliest. That gives China Railway Rolling Stock Corporation plenty of time to refine and upgrade its bullet train and push its top speed even higher.

【推荐2】On Feb. 21, four students were standing on the side of Pacific Coast Highway in Malibu when a driver going 110 miles per hour lost control of his car and it crashed into the parked vehicles.12 people were killed at the scene, including 2 drivers.
This kind of traffic death shouldn’t be called an accident. In Los Angeles, we seem to have accepted constant carnage (屠杀) in our streets in exchange for maximizing driver speed and convenience. The official responses to proven traffic dangers are mere gestures, if even that.
Los Angeles is a uniquely deadly city with a death rate that is four times the national average. Unsurprisingly, it’s also a city that has been designed with one thing in mind: a concept called level of service, which grades streets on how well they serve those in automobiles. To many Angelenos, that makes sense — to design our streets for car traffic, which is the way many get around the city. Unfortunately, we don’t recognize that there’s a trade-off. We can either have streets bettered for free-flowing traffic, or we can design streets for people to move around safely outside of cars.
City leaders consistently choose for the easy but deadly option. In one recent example, a resident asked the city’s Department of Transportation to block drivers from using Cochran Avenue at Venice Boulevard as a cut-through street, as they were speeding through a quiet residential neighbourhood. The department responded by suggesting a “speed awareness campaign” in which neighbours put up yard signs urging drivers to slow down.
People don’t drive based on signage, but they drive on the design of the street. The trunk roads of Los Angeles such as Venice Boulevard all need to be revised so that people are prioritized over cars. This would include narrowing travel lanes (道), building bike lanes, and banning right turns at red lights. These measures would make drivers feel like they’re in a city and not on a highway. A recent John Hopkins study says this would have substantial safety benefits.
With more than 7,500 miles of streets in the city of Los Angeles, they won’t all be rebuilt anytime soon. But with each road construction project, or each crash, we should be revising streets to make them safer for all road users.
The solution to traffic jam isn’t to make more space for cars. It’s to design the streets to be safe enough for alternatives such as biking, walking and mass transit, especially for the 50% of trips daily in Los Angeles that are less than three miles. The solution to protecting people dining outdoors isn’t crash barriers. It’s a street design that forces drivers to go slowly. The problem is carnage in the streets, and we know the solutions.

【推荐3】The Beijing Winter Olympics is a great success. On the Beijing-Zhangjiakou High-speed train, the crew (乘务组) welcome passengers from different countries in different languages, such as “Hello!”, “Bonjour!”, “Guten Tag!”, “Zdravstvuyte!” and so on. With their good service, passengers can make their trips happy and warm.
The Bejing Zhangiakou High-speed railway plays a very important part in many aspects. It connects the three main hosting places (Beijing, Yanqing and Chongli) together. It shortens the travel time between Beijing and Chongli from more than three hours to just one hour. The trains are well designed and have many advantages, some of which are as follows:
Smart operations
Some of the trains along the Beijing-Zhangjiakou railway line are smart enough to drive by themselves! More than 2,700 sensors (传感器) make sure the train runs smoothly. Most importantly, the trains can run in temperatures as low as -40ºC.
Large screens
Some carriages are equipped with large screens. You can watch the Olympics live shows on it with the help of 5G technology. No matter whether you are an athlete or a reporter, you won’t miss any exciting show.

【推荐1】Dancing to loud music in open spaces has been a popular way for many middle-aged and elderly Chinese people to relax and exercise. But public dancing has long been complained about because of the noise it makes.
Recently, with the help of a new device, people living near Gumei Population Cultural Park in Shanghai can now better enjoy themselves in public dancing without causing trouble for others with the loud music.
Set in a white box, the device is an amplifier that can send sound in a certain direction. Using new technology, the device controls the sound in a fan-shaped area in front of the speaker. People outside the area can hardly hear any sound.
“The device is age-friendly and it’s easy to use,” said Li Honglin from the company that made the device. The device is locked when not in use and the dancers take turns to keep the key.
Zhang Fengling, who lives in a community next to the park, said she’s glad she can now open her windows in the evening.
Gu Xinzhen, 92, who has been dancing in the park for over ten years, said the music from the new speaker is not as loud as before, which makes dancing a little less fun, but she is glad to do something for a better living environment.
Five public dancing locations in the city have also used the device. What’s more, in Suzhou, Jiangsu Province, over 1,000 public dancing locations have used similar technology. “The technology will be introduced to more places,” Li said.

【推荐2】When the COVID-19 pandemic made face masks an everyday necessity, Japanese company Donut Robotics took the opportunity and created a smart mask — a high-tech upgrade to standard face coverings, designed to make communication and social distancing easier. Connected to an app, the smart mask can record the information it accepts in a written form, make the wearer’s voice louder, and translate speech into eight different languages.
Donut Robotics first developed the translation software for a robot called Cinnamon — but when the pandemic hit, the robot project was put off. That was when the team’s engineers came up with the idea to use their software in a face mask. Donut Robotics was co-founded by Taisuke no and Takafumi Okabe, aiming to change the world with small and mobile communication robots. They applied the initiative to provide services for visitors at Tokyo’s Haneda Airport. Cinnamon robot — designed to provide tourists with useful information — was one of four translation robot prototypes selected by the project.
But earlier this year, COVID-19 hit Asia and the airport project grounded to a halt. “We were running short of money and wondering how to keep the company going,” says Ono. The team sought a solution and came up with the idea to adapt its software for a product that would sell well in the pandemic. The COVID-19 pandemic led to an increase in face mask sales. Seeing an opportunity to make money with their translation technology, Donut Robotics launched a fundraiser on Japanese crowdfunding platform Fundinno in June. They raised $265, 000 in 37 minutes. “It was very surprising,” he says, “because it would usually take three or four months to get that kind of money.”
Ono says the first wave of supply is expected to take place in Japan, with 5,000 to 10,000 masks available by December, priced at $40 to $50 each. Donut Robotics will not expand overseas until April 20.

【推荐3】A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20%-40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboatories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

【推荐1】Coffee helps millions get going. Now a company called Bio-bean wants it to get buses going too. Arthur Kay is the founder.
The company collects waste coffee grounds (渣滓) from all across the UK, from thousands of different outlets and then turns those waste coffee grounds in the factory in Cambridgeshire into advanced biofuels. The United Kingdom produces half a million tons of coffee grounds per year. Most are thrown away. Bio-bean gets grounds from everywhere from coffee shops to instant coffee factories. They extract (提炼) the oil to use as part of a 20% bio-diesel blend (生物柴油混合物). And the real driver for this is to make a fuel that’s usable with an existing engine. So the key with Bio-bean is to deliver fuels that can work at scale today.
London’s bus network is partly fueled by bio-diesel blends made from cooking oil and animal fat to reduce greenhouse gas emissions. Bio-bean’s contribution is modest. It has produced enough to run one bus for a year on 20% coffee oil. It is just a start.
If you got all the waste of coffee grounds in London, it’d be enough to power about one third of London’s bus networks, which can be a significant contribution, but it’s not going to solve everything in one go. Kay hopes to eventually produce 100% coffee-based bio-diesel and he would like to take the technology global. Coffee is one of the world’s most popular drinks and millions of tonnes of waste coffee grounds have been produced and wasted every year. So Bio-bean wants to work with companies to save money and importantly save CO2 emissions.
So your morning jolt can fuel both you and your ride to work.

【推荐2】It’s a challenging Friday morning for Jaouad Benaddi. He’s been trying to get his goat to climb an argan tree. He holds a bag of grain (谷物) to encourage a goat to join him, waiting for the goat to catch up and eat for a moment, then holds its neck to pull toward him, but the goat fights back and jumps out of the tree.
Morocco’s tree-climbing goats, which are also called flying goats, have made headlines in recent years. Often described as a unique phenomenon in the North African nation, their climbing is born and natural.
However, Liz Cabrera Holtz, Wildlife Campaign Manager at World Animal Protection, said, “These animals are being controlled and badly treated. They’re not moving freely. They don’t have access to food, water, or even shade. Being forced to stay in trees for hours is not a normal behavior.”
Actually, Morocco is experiencing its worst drought in decades, making it increasingly difficult for farmers to grow crops in this western region. Beginning in the early 2000s, some started treeing their goats to earn tips from tourists. The income source reduced after the COVID-19 hit in early 2020. But after the country’s lockdown ended early this year, the goat-display business continued.
Benaddi says he had no interest in using his goats as roadside attractions until it became too dry to grow crops. “I’m doing a job, the goats are doing a job,” he says. “The money we make is used to buy food for all of us—my family and the goats.”

【推荐3】A hospitality college in Bali, Indonesia, has begun accepting coconuts (椰子) as tuition payment as students face economic hardship as a result of the coronavirus pandemic.
When students at the Venus One Tourism Academy pay their fees with coconuts, the college will use them to harvest virgin coconut oil, UPI reported.
Alternatively, students can pay using leaves from moringa (辣木) and gotu kola plants (积雪草), which can be converted into herbal soap and sold to raise money for the academy, Food & Wine added.
The program has been running since March, after the college received a permit to allow it to operate on this basis, according to The Bali Sun.
Venus One Tourism Academy’s director, Wayan Pasek Adi Putra, told local news outlet Balipuspa News: “Initially, the tuition payment scheme was paid in installments three times, with the first installment at 50%, the second 20%, and the third 30%. Because of this Covid pandemic, we have adapted a flexible policy. We produce virgin coconut oil, so students can pay their tuition by bringing coconuts.”
He added: “We have to educate them to optimize the natural resources in their surroundings. When the pandemic is over, they will enter the world of hospitality with different skills.”
