【推荐1】Cars could soon be communicating with each other using 5G to make drivers aware of upcoming dangers, scientists claim.    1    It could also make drivers aware of potholes(坑洼) or other dangers up ahead. 

Several car manufacturers are already integrating 5G into their vehicles, including making it work as a tool to help serve the generation of self-driving vehicles.

Experts at Glasgow Caledonian University (GCU) believe the high-speed connection will also improve the reliability and capability of automated vehicles.    2    According to the World Health Organization traffic accidents cause more than 1.3 million deaths and up to 50 million people injured worldwide every year.    3     Dr Dimitrios Liarokapis, a member of the research group, said, “To have a better idea of what the future will look like, think of having such cars with sensors, which can be used to scan what’s around them.    4     With the help of 5G, a vehicle-generated early warning system that alerts drivers is possible within the next few years. Cars that are close enough to the danger area will send warning messages to other cars around them using short-range communication technologies, and also to cars further away using 5G, fast and reliably.” 

    5     Of them, earlier this year Ford showed its intention to fit 80 percent of its vehicles with technology that warns drivers about upcoming road accidents, bad weather and traffic jams.

【推荐2】We ate on the go more than ever before. Here are three health apps that can help you better manage your health when you pursue your dreams.

(1) Doctors On Demand

Doctors On Demand enables you to visit a doctor without ever leaving your home, helping you use a computer, tablet or smart phone to have a doctor video chat with you. The service will help you locate and connect you to licensed doctors, psychologists, pediatricians (儿科医生) and more. Fees can be paid with HAS & FSA. It costs $ 40 for 15 minutes with a doctor or $50 for 20 minutes with a psychologist.

(2) Text 4 baby

I’m a big fan of Text4baby for a few reasons. The free service for pregnant women and new moms works by sending text messages to your smart phone three times a week with information about how to have a healthy pregnancy and baby. And the messages are timed to the pregnant woman’s due date or the baby’s date of birth, sending tips that are relevant to where a mother is in her pregnancy or where a baby is in stages of development. Tips range from breastfeeding to car seat safety to reminders about exercise, nutrition and more. The service combines interactive text messages, an app, video and web content in English and Spanish. Sign up by texting BABY to 511-411 or by downloading the app.

(3) RISE

RISE, an app available on iPhone (coming to Android in 2016), pairs you up with (与绑定) a registered dietitian to improve your diet and reach health goals. You share photos of your meals and your exercise for the day with your coach, who then looks for areas where you can improve and gives advice, helps you set goals and is there to pat you on the back virtually (虚拟地) when you hit a milestone. What’s also great is that you can text as much as you want with your dietitian and there is no need to go into an office. Fees for this service range from $9 per month to $50 a month. There is a free 7-day trial so you can try it out for a week to see if it’s fit for you.

【推荐3】The QR-code menu—which you access by scanning a black-and-white square with your smartphone—has taken off.     1     But I hope not, because I hate those digital menus.

For restaurants, QR-code menus offer potential benefits beyond putting germ-averse(厌恶细菌的)customers at greater ease. In the near future, restaurants might use dynamic menus.    2     Besides, the prices of some dishes could also rise or fall to better match supply with demand.

    3    QR-code menus will force a distraction during the dining. You may just be checking to see what you want your next drink to be. However, from there it’s easy to start checking texts and emails.

Research conducted before the pandemic suggests that, even if everyone resists the temptation to check an incoming text message, merely having a phone out on the table makes a meal less fun for all involved.    4     The social-psychology researcher Ryan Dwyer and his colleagues randomly assigned some people to keep their phone out when dining with friends and others to put it away. “We found that groups assigned to use their phones enjoyed the experience less than groups that did not use their phones,” Dwyer said, “primarily due to the fact that participants with phones were more distracted.”

QR-code menus reduce privacy, too.    5     Many of the codes are actually generated by a different company that collects, uses, and then often shares your personal information. In fact, companies that provide QR codes to restaurants like to talk about all the personal information you are sharing along with that food order: your location, your gender, your age group, and other information about you and your period.

【推荐2】Garbage often has negative associations 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 tossed out (扔走), 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 visitors.

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 decompose. 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 and ornaments (装饰品). “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】Learning is so complex that there are many different psychological theories to explain how people learn. A psychologist named Albert Bandura suggested a social learning theory which shows that observation, imitation, and modeling play a primary role in this process.

In Albert Bandura’s opinion, people can learn through observation. Observational learning doesn’t even necessarily require watching another person join in an activity. We can also learn by reading, hearing, or watching the actions of characters in books and films. However, just observing someone else’s actions isn’t always enough for learning. Your own mental state also plays an important role in determining whether a behavior is learned or not. In addition, though in many cases, learning can be seen immediately when the new behavior is displayed, yet sometimes we can learn things even though that learning might not be immediately obvious, which means people can learn new information without showing new behaviors.

Not at observed behaviors are effectively learned. Certain requirements need to be related to the observational learning process. For example, you need to be paying attention. Also your memory is an important part of observational learning as you need to pull up information later and act on it during the process. Once you’ve paid attention to the model and kept the information, it’s time to actually perform the behavior you observed. Further practice of the learned behavior leads to improvement. Finally, you have to be motivated to imitate the behavior that has been modeled.

Social learning theory have many real-world applications. For example, researchers employ it to look into and understand ways that positive role models can be used to encourage desirable behaviors. Besides, it’s also applied in the field of education, and today, both teachers and parents recognize how important it is to model appropriate behaviors.

【推荐3】Donna Strickland is a professor in the Department of Physics and Astronomy. Professor Strickland is one of the recipients (接受者) of the Nobel Prize in Physics 2018 with Gerard Mourou, her PhD teacher at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

Professor Donna Strickland is only the third woman ever to have won the Nobel Prize in Physics. She and her fellow winners were honored for what the Nobel Committee called groundbreaking inventions in laser physics. Professor Strickland found a pioneering way to use lasers as very precise drilling or cutting tools. Millions of eye operations are performed every year with these sharpest laser beams.

“How surprising do you think it is that you’re the third woman to win this prize?”

“Well that is surprising, isn’t it? I think that’s the story of Maria that people want to talk about —that why should it take 60 years? There are so many women out there doing fantastic research, so why does it take so long to get recognized?”

Physics still has one of the largest gender(性别) gaps in science. One recent study concluded that at the current rate it would be more than two centuries until there were, equal numbers of senior male and female researchers in the field.

The last woman to win the Nobel Prize in Physics was German-born Maria Goeppert Mayer for her discoveries about the nuclei of atoms. Before that it was Marie Curie, who shared the 1903 prize with her husband, Pierre. This year winners hope that breaking this half century hiatus (间断) will mean the focus in the future will be on the research, rather than the gender of the researcher.

【推荐1】Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.

What is 5G? What difference will it really make to our lives? The “G” in “5G” refers to the generations of mobile network technologies.

1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster. Now 5G promises much faster data download and upload speeds, and more stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.

5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G.The short delay of 5G will make the games feel even more real.

Though 5G will make our lives more convenient, it will not be perfect. For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.

【推荐2】5G wireless networks are ready to power the cities of tomorrow. However, exact implementation (实施) of 5G will vary from city to city, with each city having its own unique set of priorities, requirements, and objectives.

Since 5G enables countless service possibilities, cities must develop strategies around their specific needs. Business and civic leaders play a decisive role in this process, helping to drive smart city initiatives and ensuring that key infrastructure (基础设施) elements are in place.

Several urban areas, including Los Angeles, Dallas, Houston, Atlanta, and Chicago, are early to benefit from 5G. For operators, these large urban centers offer a critical mass of solid infrastructure to support 5G’s complex technology requirements.

Now, regional and local governments play a critical role in positioning their cities to become early 5G adopters. They have a growing responsibility to streamline the permitting process, change fee structures, and minimize regulator obstacles in order to enable greater 5G implementation.

Efforts are already in full force by industry players to overcome challenges for a smooth build- out in areas where 5G is needed first. As business leaders take a more active role in ensuring that they are well-positioned to better 5G services, they also increase their ability to transform their organizations into smart companies. Peter Linder, head of 5G marketing for North America at Ericsson, emphasizes the critical role individual leaders can play in making 5G and smart cities a reality. “5G will be introduced in urban areas first, driven by consumer and business’s needs,” he says. “Proactive city leaders appreciate the potential value of 5G for developing smart city solutions and will partner with service providers to speed up vital network development.”

The role of business and civic leaders as stimulators for encouraging 5G adoption is decisive to creating smarter, safer, and cleaner cities. The time is right for urban leaders and business executives (执行官) to work together toward making smart cities a reality.

【推荐3】Do you know 5G? It is the fifth generation of mobile network technology. These new networks are coming.

China just issued commercial licenses for 5G on June 6, 2019. This means that China’s telecom companies will be able to offer 5G networks for mobile phone users.

Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G?

5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds to send and receive data. But 5G will get it down to 1 millisecond or less-this is almost real-time.

This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.

5G + entertainment

5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.

Also, virtual reality(VR) games will become more popular with 5G. The short delay of 5G will make the games feel even more real.

5G + transport

5G will also bring us safer self-driving cars. These cars can send signals to each other. They also talk to traffic lights and road sensors. 5G will allow cars to react even faster than human drivers.

5G + smart homes

5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.

For example, your toaster can automatically start making breakfast after your alarm rings. And if its sensor feels the air becoming dry, a smart sprinkler could water your plants by itself.
