Experts believe that the best time to teach kids language skills is when they are babies. Most of the time the task is easily accomplished with parents reading or talking to their babies. However, in some cases that is not possible due to busy work schedules or when kids are born deaf. Now, an adorable blue-eyed robot, a human avatar, and some high-tech neuroscience may be able to assist parents with this important developmental task.
The Robot AVatar thermal-Enhanced system, or RAVE, is the brainchild of a team of researchers led by Laura-Ann Petitto, an educational neuroscientist, at Washington, DC's Gallaudet University. The learning process begins when the robot's camera, which is focused on the baby's face, detects tiny changes in his/her body temperature. This, combined with the baby's facial expression, causes the robot to turn its head and guide the baby's attention to a computer screen, on which a human avatar starts to communicate with the baby, much like what a parent would do. For example, if the baby points towards the screen, the avatar might respond, "Are you pointing to me?" and follow that up with a nursery rhyme, fairy tale, or some essential social communication, all in American Sign Language(ASL). The "conversation" continues until the kid loses interest.
The researchers, who have been testing the system for three years, found that babies as young as 6 to 8 months old began to move their hands in a rhythm similar to ASL after interacting with RAVE for just a few minutes. Petitto says natural language, whether communicated through speech or sign, activates the same parts of the brain and believes the rhythmic motions prove that the babies are learning the essential elements of communication.
What sets this technique apart from other methods, such as showing educational videos or television shows, is its interactive nature and real-time response to the baby's actions. The researchers say that while it is too early to determine the system's long-term influence on baby communication, the initial response has been very encouraging. Next, they plan to introduce an avatar that can both sign and speak to babies.

【推荐1】One summer night, a boy felt himself lifted from bed by his father. Dazed with sleep, he saw stars flashing across the heavens. “What is it?” the child whispered. “Shooting stars. They come every year in August.” Decades have passed, but I remember that night still, because I was the fortunate boy whose father believed a new experience was more important than an unbroken night’s sleep.
Some parents like my father have the gift of opening doors for their children. This art of adding dimensions to a child brings the reward: the marvelous moment when the spark bursts into a flame that will burn brightly on its own one day. At a Golf Association tournament, a ten-year-old girl played creditably. “How long have you been interested in golf?” someone asked. “I got it for my ninth birthday,” she said.“ Your father gave you a set of clubs?” “No,” she said, “he gave me golf.”
I have a friend, a psychiatrist, who says there are two types of people: those who think of life as a privilege and those who think of it as a problem. The first type is enthusiastic and energetic. The other type is suspicious and self-centered. And he adds, “Tell me about your childhood and I can tell you which type you are likely to be.”
The real purpose, then, of trying to open doors for children is to build eager and outgoing attitudes, which is the most valuable legacy we can pass on to the next generation. But why don’t we work harder at it? Probably because sometimes we don’t have the awareness or the selflessness or the energy. And yet, for those of us who care what becomes of our children, the challenge is always there but the opportunities also come repeatedly. Many years have passed since that night. And next year, when August comes with its shooting stars, my son will be seven.

【推荐2】Imagine you need milk, so you go to the grocery store to pick some up, only to find there are dozens of options. These days, you have to make a decision on not only the percentage of fat you want, but also what source you want your milk to be coming from: cows, soybeans... You have no idea what milk to pick. There are so many choices that you are confused.
This phenomenon is known as the paradox (悖论) of choice and it is becoming a concern in the modern world, where more and more options are becoming easily available to us. While we might believe that being presented with multiple options actually makes it easier to choose one that we are happy with, and thus increases consumer satisfaction, having too many options actually requires more effort to make a decision and can leave us feeling unsatisfied with our choice.
The idea was popularized by American psychologist Barry Schwartz when he published his book, The Paradox of Choice: Why More Is Less. Schwartz, who has long studied the ways in which economics and psychology intersect (交叉), became interested in seeing the way that choices were affecting the happiness of citizens in Western societies. He identified that the range of choices that we have available to us these days is far greater than that people had in the past; however, consumer satisfaction has not increased as much as traditional economics theories might expect.
Schwartz identified that the paradox of choice carries the most consequence for people that are maximizers. Maximizers, unlike satisficers, are concerned with making the best choice instead of simply making a choice that they are happy with. When there are many options available to maximizers, it becomes harder for them to determine which is the best, which can cause them to feel a great deal of regret after they have made a choice.
Instead of believing that freedom of choice is unlimited, Schwartz advocates that the role of psychology and behavioral economics should be to find the kind of limitations on freedom that can lead to the greatest level of happiness within society.

【推荐3】Some readers majoring in computing discipline might ask, “What’s all this got to do with me? I just want to develop a computer system, build a website or create a computer animation and write a report about it, not collect and analyse data or make arguments.”
The response is that designing and creating any kind of computer-based product is still a form of research, which requires finding or generating data, analysing it and drawing conclusions. The research question is. “Is it possible to develop a computer-based product to do X?” In order to define that question fully (for example, What is X? Why is it important to have a computer system to do X?), and then to answer it, you will have to gather data about the computer-based product required, generate your own data to document how and why you designed and implemented the product, and test the computer-based product and obtain user or viewer feedback, which will involve more data generation and analysis.
Ultimately, you will have to convince the readers of your report that you went about the design and development tasks in a systematic way, finding, generating and analysing appropriate data, so that you could draw conclusions about whether or not you could indeed develop a computer system to do X.
Of course, some systems development is fairly trivial, for example, using a PC-based software package to build a database to keep track of your music collection. To satisfy academics as a valid (有效的) piece of research, the computer-based product must contribute something new, for example, the system includes some new functions not previously automated using Information Technology (IT), or its design is based on a new theory or algorithm, or the system exhibits some new artistic ideas. Viewing the design and creation of computer systems as research is discussed more fully in Chapter 8.
As explained above, increasingly researchers who build computer-based products are also being encouraged to evaluate their products in use. Effectively, a new research question is being added to design and creation projects — What happens when the computer-based product is used in practice or viewed by an audience? To answer that question, researchers have to use one or more of the other strategies and data generation methods described in this book.

【推荐1】Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people's names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend proceeding with caution.
The app, called Social Recall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody," says Barry Sandrew, whose start-up, also called Social Recall, created the app and tested it at an event attended by about 1,000 people.
After receiving an invitation to download Social Recall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee's face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app’s creators say it automatically deletes users’ data after an event.
Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you”.
The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness”, a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone's face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user's phone, according to the team behind the app.

【推荐2】What do earmuffs, swim fins and Popsicles have in common? They were invented by curious, creative kids—some as young as you.
“Kids are creative thinkers with their own ideas for solving problems. Going through the invention process—identifying a challenge, designing a solution and testing to see if it works—is empowering,” said Tim Pula, an invention and innovation specialist at the Smithsonian Institution, “ For kids who are comfortable with problem-solving and risk-taking, the future is a world of possibilities,” Pula added.
The future looks bright for the Leschinsky siblings of Mahwah, New Jersey, Mark Leschinsky invented a self-disinfeeting hazmat (protective) suit for health care workers when he was 9 years old It earned him a place in the National Gallery for America’s Young Inventors in 2015. The next year he was joined by his brother, Gary, who invented an allergy-alert watch when he was 8, Doth products have received U. S. patents, protecting the boys’ rights as inventors. Because they were too young to file the applications, their dad did it for them. “I want to make a difference by helping people,” said Mark, now 15. “If there’s a problem that can be solved,I want to be involved.”
Gary, now 14, has a personal tie to his invention. “Like millions of kids, I struggle with food allergies on a daily basis,” he said. “Children with allergies often are unaware that a reaction has started,” Gary said. So he created a watch-like device with sensors that measure itching(刺痒), sweating,heart rate and other body responses. A severe attack can quickly become life-threatening. Gary’s watch has a built-in alert for a parent or guardian.
Watching her brothers has inspired 12-year-old Barbara Leschinsky. An inventor since age 7, she created a toothbrush that gives a reward when used properly. Now she’s working with Gary and Mark on a face shield that cleans itself with germ-freo air. “It’s cool that you can make something that makes others, lives easier,” said Barbara,who hopes more girls and women get involved in innovation.

【推荐3】Flying cars have been growing in popularity in the past few years with even big players such as Boeing and Porsche looking to develop these vehicles. Now, a city in England is hosting the world’s first airport for flying cars.
British-based start-up Urban-Air Port has partnered with car giant Hyundai Motor Group to engineer this futuristic airport in order to give everyone a taste of what is to come in the future of air travel. They are calling their new construction the Urban Air Port. The new project will develop a zero-emission infrastructure (基础设施)that will host the next generation of electric and autonomous air vehicles.
Cars need roads, trains need rails, planes need airports, and electric vertical take-off and landing (eVTOL) aircraft will need Urban Air Ports — Air-One, which will bring clean urban air transport to the masses and create a new airborne world of zero-emission mobility. The Urban-Air Port will improve connectivity across our cities and boost productivity. An Urban Air Port is 60% smaller than a traditional heliport, can be built in a matter of days, and can be moved to alternative sites if the need arises. It’s also extremely eco-friendly as it emits net-zero carbon emissions.
An Urban Air Port can support any eVTOL aircraft and is ideal for emergency circumstances as il can rapidly deploy drones and other eVTOL aircraft to transport supplies, equipment, and people where needed most.
In I he meantime, Hyundai has stated that it has plans to create its own eVTOL aircraft and is supporting the development of Air-One as part of its plan to commercialize its aircraft by 2028. The new airport was built in Coventry, a oily in central England y and it was ready by the encl of 2021.

【推荐1】When your pen is broken, the batteries (电池) in your toys run out, or you have some leftover food, what will you do with these things? You will probably throw them all into one bin. But actually, all of these pieces of rubbish need to be sorted (分类) separately.
Rubbish sorting is a big problem worldwide. In recent years, some Chinese cities have been working hard on it. Shanghai has worked with Alipay to create a “green account (账户)” service. Account owners get points by correctly sorting their rubbish. Through the Alipay app, they can exchange the points for milk, phone cards or other products. The city is asking all people living there to sort their rubbish into four groups: wet, recyclable, harmful and dry.
Wet waste is something you don't want but that pigs can eat. Plastics, glass, paper and other things that can be reused are recyclable waste. Harmful waste includes things like medicine, batteries and bulbs. Finally, any waste that’s not wet, recyclable or harmful will go in the “dry waste” bin.
Many other Chinese cities are also sorting their rubbish in this way. For example, Shenzhen has been doing this since 2012. Students there also receive waste-sorting guidebooks that they must study.
In fact, there are still many workers specially working for sorting rubbish by hand in China. There is still a long way to go. But it’s never too late for every Chinese to learn how to sort rubbish properly and protect the environment.
If you don't sort your rubbish, all of it will go to a landfill (垃圾填埋场) and be buried together.
These landfills can take up much ground that could be used for planting. The electronic waste you throw away, such as batteries or used mobile phones, can cause pollution. Other pieces of rubbish, like the metal part of a pen, can be used to make other things if they are properly recycled.

【推荐2】On March 20, the U. N. International Panel on Climate Change(IPCC) released the final volume in a series of reports outlining experts’ latest understanding of climate science. It warned that even with urgent action we will face a dramatic increase in catastrophic events—from droughts to floods—that have become signs of a rapidly warming world. But the most worrisome things are the “known unknowns”—potential outcomes scientists know could happen even if they don’t know exactly when or how.
It’s striking how little we know about them. Take the Atlantic Meridional Overturning Circulation(AMOC) for example. This system of ocean currents is a key regulator(调节器) of Atlantic Ocean temperatures and, in turn, maintaining land temperatures, particularly in North America. If it collapsed, it would remake weather patterns and disturb “human activities”.
Another known unknown is the scale of sea-level rise. It is estimated that global average sea levels are expected to rise up to 1m (about 3 ft.) by 2100. But because the science of rapidly melting ice sheets remains difficult for scientists to understand, that number could also end up being 2m in the same time frame.
The more the planet warms, the more likely we are to experience unpredictable catastrophic changes. Climate events like these are referred to as tipping points: singular climatic events that can instantly reshape our understanding of climate systems. The new report also points out how the future becomes more difficult to predict as climate change continues. Impacts that scientists could forecast today will become more difficult to predict effectively when they are combined with other climate effects. Food insecurity, for example, could drive changes in agricultural practices, which would in turn affect the climate.
According to three decades of IPCC reports, it’s easy to see how the science has become more certain and more urgent. The IPCC is not expected to publish another report for at least six years. In that time, the science will evolve, as will the human impacts. By then we should know more about these known unknowns, too. We can only hope that the knowledge brings relief, not the alternative.
