Restaurants, schools, dentist offices are all keeping more windows open, to increase ventilation — and hopefully, to decrease the chances of encountering the coronavirus. But letting in fresh air also lets in more noise.
Now, researchers have come up with a device that’s like noise-cancelling headphones — but for a building.
“It works on the same principle, so it detects noise that’s coming into the windows, and then is cancelling the noise.” says Bhan Lam, an acoustical engineer at Nanyang Technological University in Singapore. The device looks like a grid of small speakers, and fits over an open window.
A microphone samples incoming noise, then sends the speaker grid instructions on what sort of “anti-noise” to emit. The result is to cancel out the incoming sound.
For example, here’s the sound of a commuter train in Singapore, with no noise control. (Before Control SFX) Now, here’s that same train sound, with the array of noise-cancelling speakers turned on. (After Control SFX)
Compare that to a closed window (Window Closed SFX). The anti-noise device is almost as good, and allows air to keep flowing into and out of the window. The details are in the journal Scientific Reports. The device is just a prototype (样机) — so it’s still expensive.
And it doesn’t block out all sounds. It masks sound at frequencies from 300 to 1000 Hz — which includes the rumble of freeways, trains and planes. But even that could come in handy in a place like Singapore. “Give me a second, there’s a plane flying past.” Bhan says Singapore already has a lot of green buildings that use natural ventilation. “But the downside is, when you have lots of openings in the buildings, the noise comes in, so you need some way to manage the increasing noise.”
A grid of window speakers could do the trick — especially if people prioritize peace and quiet over a good view, which folks at home tend to do all night.

【推荐1】Teaching artificial intelligence to understand simple physics concepts, such as that one solid object can’t occupy the same space as another,could lead to more capable software that takes less computational resources to train, say researchers at Deep Mind.
Now,Luis Piloto at Deep Mind and his colleagues have created an AI called Physics Learning through Auto-encoding and Tracking Objects (PLATO) that is designed to understand that the physical world is composed of objects that follow basic physical laws.
The researchers trained PLATO to identify objects and their interactions by using simulated(模拟的)videos of objects moving as we would expect, such as balls falling to the ground, rolling behind each other and bouncing off each other. They also gave PLATO data showing which pixels(像素)in every frame or photo belonged to each object.To test PLATO’s ability to understand five physical concepts, such as solidity, persistence (that an object doesn’t tend to vanish) and unchangingness (that an object tends to retain features like shape and colour), the researchers used another series of simulated videos. Some showed objects obeying the laws of physics,while others depicted ridiculous actions. They tasked PLATO to predict what would happen next in each video, and found that its predictions were reliably wrong for nonsensical videos,but usually correct for logical ones, suggesting the Al has an intuitive(直觉的)knowledge of physics.
Piloto says the results show that an eccentric view of the world could give an Al a more generalized and adaptable set of abilities.“If you consider,for instance,all the different scenes that an apple might be in,”he says.“You don’t have to learn about an apple on a tree,versus an apple in your kitchen, versus an apple in the garbage. When you kind of separate the apple as its own thing, you’re in a better position to generalize how it behaves in new systems,in new contexts.It provides learning efficiency.”
“This is somewhat like teaching a kid what a car is by first teaching them what wheels and seats are,”Chen Feng at New York University says.“The benefit of using object centric representation, instead of raw visual inputs,makes Al learn intuitive physical concepts with better data efficiency.”

【推荐2】A team of engineers at Harvard University has been inspired by nature to create the first robotic fly. The mechanical fly has become a platform for a series of new high-tech systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
“It’s extremely important for us to think about this as a whole system and not just a bunch of individual components (零件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. “The added difficulty with such a project is that actually none of those components are off the shelf and so we have to make them all on our own,” he said.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings has a number of individual components, each of which individually has to perform well, and then has to be matched well to everything its connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says the success of the project proves that the flying robot with these tiny components can be built and manufactured.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”

【推荐3】The history of the school bus can date back to 1886 when the Wayne Works company made horse-drawn carriages (四轮马车) known as “ school wagons” or “kid hacks” in Indiana.
In the early 1900s, the car industry was beginning to develop fast.
In 1927, a man built the first bus that primarily used steel. Before long, Wayne Works introduced the first all-steel school bus body with safety glass windows.
Many new national standards were created, determining everything from seating designs to the famous yellow color that school buses still sport today. The reason why the color was chosen was simple.
A.Horses were easy to control. |
B.Not all chose to paint their buses yellow. |
C.Yellow is quite eye-catching to human beings. |
D.Before then, many children simply walked to school. |
E.Now, school buses have had many more improvements. |
F.Still, parents were increasingly concerned for children’s safety. |
G.This gave Wayne Works a great opportunity to improve its carriages. |
【推荐1】Some decades ago, when kids turned 16, they couldn’t wait to get their drivers’ licenses. It represented freedom, independence and the first big step into adulthood. It was thought that kids who didn’t have a license at 16 either were really bad drivers or really uncool.
Today, conversely, many teenagers are deciding to wait to get their drivers’ licenses, according to several recent studies. One this year by the Centers for Disease Control and Prevention found that the percentage of high school seniors who had a driver’s license fell from 85% in 1996 to 73% in 2010.
Some experts, like Michael Sivak,director of Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute, argue that at least part of the drop is permanent and that it’s part of a global decline in driving among young people. He says that the change is rooted in the growth of access to the Internet. Modern teens can connect with each other through social media, so there’s less of a need to get together by driving to some places. “I believe that a large part of the drop is permanent,” says Sivak. “It’s not just teens. It’s people in their 20s and 30s, as well.”
Other researchers, including Robert Foss, director of the Center for the Study of Young Drivers at the University of North Carolina, believe that the recent recession(经济衰退) simply had a greater influence on young drivers than others. They had less money to purchase a car, less money to buy gas, or they couldn’t find jobs to buy either, he says. The economy was a major cause for the decision to wait. The most common reasons for waiting were not having a car, being able to get around without driving, gas being expensive and driving being expensive as well.
The family income also played a key role. Among young adults in households with an annual income of at least $60,000, 60% got a license within one year of their state’s minimum age for doing so and 72% were licensed before the age of 18. In households with an annual income of less than $20,000, only 16% got a license within one year of becoming eligible, and 25% got licenses before turning 18.

【推荐2】Most people think that the capital of the movie world is Hollywood, in the United States. However, the real movie capital is Mumbai, in India. Mumbai used to be known as Bombay, and so the film industry there is called “Bollywood”. Each year, Bollywood makes twice as many movies as Hollywood.
The movies from Bollywood are very different from Hollywood movies. For one thing, Bollywood movies are longer than most Hollywood movies. Most Bollywood movies are more than three hours long, and contain singing, dancing, adventure, mystery and romance. Because Bollywood films has so many different characters, this style of film is called a “masala” film. Masala is an Indian word for a mixture of spices.
Another big difference is the way the movies are made. It takes longer to make a movie in Hollywood than in Bollywood. In fact, filming may begin on a Bollywood movie before the script is finished. The director and writers can make up the story while the filming is being made. Sometimes they even write the script by hand instead of typing it.
Bollywood actors are so popular that some of them may even work on several movies at the same time. They may even make several different films on the same day using the same costumes and scenery. Since most Bollywood movies follow the same kind of story, shooting scenes for several films at the same time is not a big problem for actors or directors. This also helps to keep the cost of Bollywood movies lower than the cost of Hollywood movies.
1. What is Not True about Mumbai?A.It is the movie capital of India. |
B.The new name is Bombay. |
C.More movies are made there than in Hollywood. |
D.It is less expensive to make films there than in Hollywood. |

【推荐3】Garbage has been negatively connected with germs(细菌), dirt and useless junk. However, a recent art exhibition proved that “useless” things can have practical significance.
Dear Pretty Rubbish, an art event organized by the World Wide Fund for Nature (WWFN) and digital media art company Blackbow, was held in Beijing. It looked at wasteful consumption (消耗) and asked questions about the relationship between our lifestyles and our garbage.
“We hope that everyone who visited the show can think about how ‘useless things’ are produced why they are throw away, and whether ‘useless things’ are really useless, ”said Cao Yujia, the design director of Blackbow.
The organizers said that all the raw materials for the exhibition were collected from community garbage cans.
Artists Zhou Yuxuan and Liu Yifan collected nylon cable ties (尼龙扎带), LED lights and beverage bottles from designers’ workshops to create a work where plastics, in the shape of cells “grow” in a corner. There, the lights blink (闪烁) regularly to imitate (模仿) “breathing”. When people walk near it, the work responds by forming light patterns, as if communicating with the visitor.
Speaking about the work, Zhou said. “It’s like some kind of communication between humans and plastics.” Plastic has a life longer than almost any creature, taking centuries to break down. Though people blame plastics for damage to the environment, they are a big part of our daily lives.
“So we want to ask the question: Although the damage continues, whether there is a way for humans to reconcile (调和) with plastics,” said Zhou.
Liu said that plastic waste can be used to make clothes “Re-use of plastics will be a future trend, ” he said. Cable ties are a useful and common material for fastening. Many people will buy a large bundle of them but only use a few pieces. The rest of cable ties could be re-used as a decoration in handicrafts.
“This exhibition calls for everyone to re-think their wasteful lifestyle full of single-use plastics and make changes, ”said Cao.

【推荐1】Twenty-three elementary schools in Orange County, Florida, have been cutting back on recess(休息), and even canceling it altogether to increase class time. In a recent Orange County School Board meeting, parents asked that recess time be carried out in all local schools for all students.
Angela Browning, a parent in the area, said that schools provided 0 to 30 minutes of recess per day.
“Five-year-olds not getting recess is nothing short of abuse ,” said
Browning , who added that her twins, who are in the second grade, had attention- deficit hyperactivity disorder(ADHD 注意力缺陷多动障碍) and benefited from taking a break to use up some of their energy. “We will not accept a ‘recess for some, but not all’ approach.”
“They have become machines that produce data as opposed to children,”
Amy Narvaez, a mother of two children said.
At the center of issues in Florida are Common Core exams, mandatory(强制 的)standardized tests in math, language, arts and literacy(读写能力), where the students’ performance often decides teachers’ pay and sometimes their jobs. Many teachers are using that extra 20 minutes to teach the test.
“Because so much of the money is tied to the schools’ scores and their grades, everybody is pressured,” said Diana Moore, president of the Orange County Classroom Teachers Association.
“We’ll come to a place in Florida and probably nationally where we have to admit that we really don’t have enough minutes in the day to get everything done for our children,” said Orange County Public Schools leader Barbara Jenkins.
The decision of whether recess takes place, and for how long, has thus far been up to each school’s principal.
“Florida law requires that districts provide 900 teaching hours during the school year,” Florida’s Department of Education press secretary Cheryl Etters said in a statement. "Whether recess is part of the school day is a decision made by the school board(学校董事会)”
Canceling recess also can taper off chances for children to learn social skills, according to many experts. Many children take advantage of their rest to learn skills, according to some experts. If recess is canceled, they have to give up.
“At the end of the day, who cares if you have straight A’s and you get a scholarship to Harvard if you act with no skill?” Heather Mellet, a mother of two children in the district said.

【推荐3】Steve Sterner's job as a pianist playing music for silent movies started on a fancy idea about four decades ago.
He was at a friend's party and decided to make sound by beating the ivories(象牙)while a silent cartoon played. Impressed with the performance, his friend invited him to play along to a full-length feature silent film at the theater.
This fall, Mr. Sterner, 67 years old, is celebrating his 35th anniversary as a piano accompanist at Film Forum by playing 12 silent movies of his choice at the theater in Greenwich Village, He has picked movies starring Harold Lloyd and Buster Keaton and ones directed by Frank Borzage. The series started in August and goes until early November.
''All these films are wonderfulsaid Mr. Sterner, who is also an actor and a singer. '' People might not have heard of or seen them, but they are little gems(宝石)waiting to be discovered. "The silent-film era peaked almost a century ago and fizzled out with the arrival of the talkies, or movies with synchronized(同步的)sound. But now, silent films are making a comeback in New York City, with increasing popularity among young people.
Film Forum, a nonprofit, puts on two to three silent movies with live accompanying music every quarter, including at least one silent comedy for its junior audience. These showings are always popular and often sold out, with at least 100 people typically attending each screening, according to its program director Bruce Goldstein.
Over the past three decades, he said he has seen more people, especially younger audiences, coming to see silent films.
"For many years people didn't pay attention to silent films," Mr. Goldstein said. "But now people discover that silent films are the roots for movies,"
“I feel like today because of smart phones and social media, our left brain is filled with information. Silent films, more than other forms of cinema, engage your right brain and use your imagination, Mr. Model said.

Start by changing your opinion, says Caitlin Kelly, the author of Malled, a book based on her experience as a sales clerk after losing her job in journalism. “Don’t focus on what you’re not getting but what you are getting,” she says. “Be patient and work attentively with a wide range of people. It doesn’t matter what the job is –there are always things you can learn and skills you can develop.”
Hilary Pearl, the founder of a coaching firm, says, “Tell yourself the current situation isn’t the end of your career. Don’t overdramatize(过分夸大)the negative aspects but try to view the situation more philosophically: life has a series of stages, and this is one of them. Don’t forget to study even in the worst stage.”
Consider that because you’re overqualified, you may be able to learn or do things on the job that might not have been possible in a more demanding position, says Sarah Hathorn, the chief executive of Illustra Consulting. “You could spend your extra time in learning different aspects of the business and teaching others in the organization,” she says.
Is it possible to make your work more challenging, even if your job responsibilities aren’t likely to change?
Of course, you may seek tasks and responsibilities that force you to learn something new or to work harder. “You may be operating on autopilot(习惯性地)right now, but chances are that people above you are stressed,” Sarah Hathorn says. “take things off your boss’s plate and let him know which projects or tasks you want to learn more about.”
Always express your request positively, saying that you love new challenges, rather than complaining that you’re bored and underused, says Ethun, the president of the Park Avenue Group. In your down time, educate yourself about the company and its industry. “Read corporate information, analyst reports and related news articles,” she says. “If your boss accepts your suggestions, it will make you a more valuable employee.”

【推荐2】When you feel that midafternoon slump(消沉) is coming on, should you fight it and get on with your day, or lie on the couch for a while. This may not be a problem that a huge number of people fight with regularly. But a new study suggests that if you’re watching your blood pressure, taking a midday nap may be a step in the right direction.
It’s long been known that naps, when done right, can leave you feeling fresh and energetic. Whether they can carry any immediate cardiovascular(心血管的) benefits has been less clear, even though this could affect the health of millions of people around the world.
“We all know that lifestyle changes stand for the basis of treatment for high blood pressure,” says Manolis Kallistratos, MD, an expert at Asklepieion General Hospital in Voula, Greece. “We also know that certain cultures have the habit of sleep during midday.” These two observations led Dr. Kallistratos and his colleagues to survey the effects of napping on blood pressure in a number of different ways.
On March 18, a study was showed at the American College of Cardiology 2019 meeting in New Orleans. Scientists wanted to find out whether taking a nap can influence people whose blood pressure is fairly well controlled, but who could still benefit from lower levels. The study included 212 adults with an average age of 62, whose average systolic blood pressure was 129. 9 mmHg. The researchers found that people who napped had systolic blood pressure that was 5. 3 mmHg lower, on average than in those who didn’t nap.

Emojis are a kind of special language. Picture are used to put meaning across. They show what people think about, like and care about. They can be used to stand for different groups of people. Unicode Consortlum is in charge of choosing offical emojis faces with different skin tones(肤色)were added. In 2016, different jobs were added, such as doctor, police officer and painter-along with female versions of these jobs. This year, emojis of disabled people were added, including emojis of blind people and people in wheelchairs.
But there is also more to emojis. They can also refer to pop culture.
New emojis in 2019 have included several animals, such as sloths(树懒)and flamingos(火烈鸟). These animals are not very common, but are known to many people. For example, sloths have become popular thanks to the 2016 film Zootopia. Many fashion designers have included flamingos in their designs in recent years. This animals makes people feel like they’re on a tropical(热带的)vacation.
