2 . Google Cloud is racing to roll out new features and services aimed at helping its customers maintain business during the coronavirus pandemic, including a new security product expected to launch Tuesday. The new security product includes technology that could attract more businesses, especially those in highly regulated industries, to adopt cloud services. The technology protects data while it is being processed. “We wanted people comfortable in knowing they can move to the cloud and don’t have to worry about the security of their data,” said Mr. Kurian, chief executive of the unit.

Google Cloud accelerated the development of several features for its virtual meeting product, Google Meet, in April, including one that automatically filters out background noises such as keystrokes and dog barks. Another feature automatically adjusts a user’s video with lighting variations. In 2018, the company launched an AI tool for manufactures that automatically inspects products for quality.

Google Cloud also benefited from the protocols(协议) for Black Friday, when shopping websites see a rush of online shoppers, to deal with sudden more demand for cloud services. The protocols benefited the customers in online videogames, government services, education and shopping, who needed assistance in more computing capacity.

Also, the protocols benefited many companies. Godbole, chief information officer for home improvement company Lowe’s Cos., worked with Mr. Kurian and his team in March and April to manage increased business. Lowe’s customers were doubling on projects such as those related to home offices during those months, and “Our company saw tremendous demand,” Ms. Godbole said.

The coronavirus pandemic presented a new opportunity for Google Cloud to prove its value for customers, said Plummer, chief of research for cloud computing. “Google Cloud aims to differentiate itself by being known as a provider that can handle unpredictable events,” Mr. Plummer said. It aims to do that by offering secure remote-work tools and software development tools that require minimal coding. “Trust is built in times of crisis,” he said.

3 . Boston wants to be smarter. The city has taken advantage of technologies to become more responsive to its residents' needs. But technology alone is not sufficient to make today's cities liveable. Boston has discovered that it also needs to reach the old-fashioned low-tech community and integrate that technology with city life.

Kris Carter rolled out Boston's smart city program in 2014. It started with an App that residents could download to report locations where sidewalks needed repair. The city sorted out those reports and ranked them in a database, which repair crews used to prioritize their work.

The system worked beautifully, except for one problem: most of the alerts(警报) came from wealthier neighborhoods, where the concentration of smartphone - equipped residents was highest. ＂The complaints from the App didn't always correlate with the greatest community need for repairs, " explains Carter.

Carter's group has moved away from the model common to many smart city initiatives of letting tech-savvy(精通技术的）residents drive the process. Instead, they run meetings to find out what problems people in different neighborhoods care about solving. When it came to sidewalks, Boston introduced a second method of collecting repair tips, hiring people to get out and walk the city's 1,700 miles of sidewalks to take notes on their condition.

Whether using low-tech or high-tech approaches, says Carter, to stay smart, a city needs to continually reassess its options to spot opportunities to improve residents' lives. Take the sidewalk repair program, walking on the streets was proved a useful, if inefficient way to prioritize repair needs. But last year the group found that walkers' mobile phones could be tracked as they moved along the streets, and that data could be analyzed to identify sidewalk routes which are most often used by neighborhoods.

“Combined with our other sidewalk information, that gave us an even better way to predict where faster repairs would do the most good," says Carter,"We're really always looking for whatever mix of approaches best solves the problem."

4 . The concept of ownership comes so easily to humans that even preschoolers have got it. Robots, on the other hand, often struggle to grasp such abstract concepts. Now a well-mannered robot that can make it has been programmed.

“Teaching robots ownership-related etiquette (礼仪) is really, really worthwhile,” says Matthias Scheutz, a computer scientist at Tufts University. "We can't just send out robots who are unaware of who owns what... If I instruct a robot to ‘build a fence’, and it goes to the neighbor’s and starts ‘stealing’ boards, that's not what we have in mind.”

The new socially conscious robot can learn who owns what from clear statements as well as its own observations. The robot learns its code of conduct (行为准则) from direct orders and generalizing from specific examples. For instance, if the robot is told not to touch several objects that it knows belong to specific people, the robot will deduce that, as a general rule, it shouldn’t touch owned objects.

Artificial intelligence (AI) expert Xuan Tan and colleagues at Yale found out how the robot reacts in experiments with blocks on a table. In one session, Tan played with only the red blocks, leading the robot to infer that these blocks belonged to the same person. When Tan instructed the robot to throw away everything on the table and the machine reached for a red block, Tan stopped the robot, saying, “That's mine.” Now aware that it should not throw Tan’s belongings, and assuming that the rest of the red blocks belonged to Tan as well, the robot cleared the table of everything but red blocks.

Later, when Tan's colleague Jake Brawer directed the robot to throw out a red block, the robot replied, "Sorry, I'm forbidden to throw it away if it's owned by Tan.” Though robots may have more difficulty understanding who owns what in situations filled with far more objects of much wider variety than blocks on a table. Scheutz called it a good "first attempt” at equipping robots with an appreciation of ownership.

5 . Recently I read Nineteen Eighty-Four, a novel by George Orwell set in a state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as ‘ungood’, ‘plus good’ and ‘double plus good’ to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it’s already happening. I type messages to my friends and alongside each is the emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our excessive use of emojis, are we losing the beauty and diversity of our vocabulary?

English has the largest vocabulary in the world, with over one million words, but who’s to say what it’ll be like in the future? Perhaps we will have a shorter language, full of saying ‘cry face’ if something sad happens or using abbreviations (缩写) like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began – the new language? Or is this a classic case of the older generations saying, ‘Things weren’t like that when I was younger. We didn’t use emoticons to show our emotions’?

Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what’s even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to transcend time and language. Images, be it cave paintings or emojis, allow us to convey a message that’s not restrictive but rather universal.

6 . Maybe you’re depressed because you didn’t sleep well. Or you feel stuck when you read an email with some bad news that prevented your enthusiastic imagination. Whatever the case may be, you tell yourself working now is in vain (徒劳的), because you couldn’t possibly come up with anything inventive in this mood.

Several studies in psychology have shown that negative emotions narrow our vision and limit our thinking. However, positive emotions can improve creativity because they broaden our way of thinking by encouraging us to try new things or look at situations differently.

Creativity is the ability to produce and carry out both new and useful ideas. Creativity can result from a person’s own creative ideas and observations, or it can appear as a response to a direct assignment or problem as well.

Both positive and negative moods can lead to two different kinds of creativity that benefit different tasks. Research shows that the key factor influencing our creativity is not our mood itself, but the strength of our feelings and the motivation (动机) behind our work. For example, anger or anxiety can help us to focus our attention on producing effective results. Great excitement or joy, on the other hand, can encourage an instant at which the solution to a problem becomes clear all of a sudden. In fact, one study even finds that while we’re 20 percent more likely to have creative abilities to understand mixed situations when we’re feeling good, people in a negative mood perform better when the quality of solutions—not quantity—matters most.

But of course, we are rarely entirely happy or entirely sad. More often, we experience mixed emotions. In psychology, these strong emotions whether they are positive or negative, lead to greater creative actions.

It comes as no surprise then that highly creative people tend to be very familiar with their emotions. They report experiencing very strong emotions more frequently than less creative people and are more willing to experience those emotions.

7 . People who drink a lot of sugary drinks have a high risk of developing cancer, researchers announced last week. However, the evidence cannot yet confirm a direct connection between the two. The researchers said the findings of a large study in France suggest that limiting the amount of sugar-sweetened drinks may help reduce the number of cancer cases. Drinking sugary        drinks has become more common worldwide in the last several decades. Sugar drinks are linked to obesity-the condition of being extremely overweight-which increases a person’s cancer risk.

The study was published in The BMJ British medical journal. It looked at data from just over 100,000 French adults-21 percent of them men and 79 percent women. The researchers noted how many sugary drinks each of them had, and followed them for up to nine years-between 2009 and 2018. The researchers appraised their risk for all types of cancer, and some individual ones such as breast, colon and prostate cancers.

The scientists found that a 100 milliliters increase in sugary drinks was linked to an 18 percent increased risk of overall cancer and a 22 percent increased risk of breast cancer. The researchers looked at those who drank fruity juices and those who drank other sweet drinks. Both groups, they found, showed a higher risk of cancer overall.

For prostate and colorectal cancers, no link was found. The researchers said this might have been because there was only a limited number of cases of these cancers in the study group.

Experts not directly involved in the work said it was a well-run study, but noted that its results could not establish cause and effect. Amelia Lake is an expert in public health nutrition at Britain’s Teesside University. She said that while this study does not provide a definite cause and effect between sugar and cancer, it does add to the importance of efforts to reduce sugar intake. “The message from the totality of evidence on excess sugar tonsureption and various health outcomes is clear,” she said.

8 . The driver who cuts you off in traffic.The neighbors who don't pick up after their dog.Situations such as these get our hearts racing and send our stress levels skyrocketing.Anger isn't a pleasant feeling.Some of us bottle up the emotion, while others explode in a wild rage (狂怒).Both habits do considerable harm to our bodies, our minds, and our relationships.

“Anger may fee1 uncomfortable and a lot of people think they have to get rid of their anger," says Patrick Keelan, a registered psychologist in Calgary, Alberta.“But anger is an emotion built into us to signal that something needs to be addressed.When we take notice of that signal and actually wrestle with the problem instead of turning a blind eye to it, we' re usually much better for it.”

Unfortunately, many of us have been conditioned to keep our emotions hidden.Increasingly,research is suggesting that this can have long-term effects on our health.Investigators at the University of Rochester noticed that people who contain their emotions tend to live shorter lives.When we're angry, stress hormones are released, which can make us more likely to develop a wide range of diseases, including diabetes, depression, immune related conditions.

Is it better, then, to scream and howl whenever something makes you mad? That's probably the reason why“rage rooms" have popped up in many American cities, where folks are invited to let steam off by violently smashing (打碎) stuff in a“safe" environment.However, the research indicates that when people display anger aggressively, it can actually increase the intensity of the anger -- and increase the likelihood of aggressive actions in the future.It doesn't take much imagination to predict how such behavior can affect your relationship with your spouse, your kids, or your colleagues.It also hurts your health.A large 2016 study at McMaster University found that people are more than twice as likely to have a heart attack after an angry explosion.

If we shouldn't bottle up our angry feelings but aggressive behavior isn't healthy either, how should we handle things that tick us of? It's the extreme highs and lows that cause the damage.If you're able to apply techniques that smooth out some of those peaks and valleys, you can have a gentler ride.

9 . Parents around the world often urge children over and over-wash your hands! It can be difficult, however, to get children to remember to wash. But what if washing hands was connected to a fun creative activity? What if instead of simply reaching for the soap, a machine could drop it right into your hands?

Well, such a machine was recently built by a boy and his sister in the U.S. state of Maryland as part of a creative competition.The not-for-profit Rube Goldberg Organization is holding the competition.

Every year, the Rube Goldberg competition assigns a specific task, considering inventions that use complex systems to carry out a simple everyday task. At first, the task for 2020 was supposed to be “turn on a light.” But when the COVID-19 happened, the task was changed to “drop a bar of soap into someone’s hand.”

Those taking part in the competition are schoolchildren. But with schools closed to slow the spread of the virus, organizers changed the rules. This year, the team can include any family members and people were asked to send in recordings of the machines to compete. One thing has not changed: The machine must complete the task in less than 10 steps.

In Maryland, the Diel family wanted to enter. So, Caitlin and her brother Ben designed and built their own Rube Goldberg machine. Next, they had to demonstrate that it could complete the task-throwing the soap just right to be caught in someone’s hand. After 106 failed attempts, they finally had success. With their video demonstration, they can now enter the competition.

Dr. Anne Glowinski teaches child psychiatry (精神病学) at Washington University School of Medicine in St. Louis. She said that “creativity and play” connects with children. It is better than the message. “We have to wash our hands because of this horrible virus”. Glowinski added.

10 . The connection between people and plants has long been the subject of scientific research. Recent studies have found positive effects. A study conducted in Youngstown，Ohio，for example, discovered that greener areas of the city experienced less crime. In another，employees were shown to be 15% more productive when their workplaces were decorated with houseplants.

The engineers at the Massachusetts Institute of Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions. These include plants that have sensors printed onto their leaves to show when they’re short of water and a plant that can detect harmful chemicals in groundwater. ＂We’re thinking about how we can engineer plants to replace functions of the things that we use every day,＂explained Michael Strano, a professor of chemical engineering at MIT.

One of his latest projects has been to make plants glow(发光)in experiments using some common vegetables. Strano’s team found that they could create a faint light for three-and-a-half hours. The light，about one-thousandth of the amount needed to read by，is just a start. The technology, Strano said, could one day be used to light the rooms or even to turn trees into self-powered street lamps.

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plant’s lifetime. The engineers are also trying to develop an on and off＂switch＂where the glow would fade when exposed to daylight.

Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmission(传输).Glowing plants could reduce this distance and therefore help save energy.
