1 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.
But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.
Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.
Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.
In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.
Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

2 . J. K. Rowling frequently shows there is magic every day. Her Harry Potter series has helped people through times of stress and depression and she is always there to deliver wise words of encouragement.
She is one celebrity who is very active on Twitter. So when a single dad named Matt Burke sent her a message thanking her for the series, she noticed. Her series had helped strengthen his relationship with his 9yearold daughter Bailey.
He included a link to his article titled Being a Broke Parent. He explained how he hadn’t found a level of financial stability that allowed him to pay bills on time and take his daughter on more activities and events. The family also doesn’t have the Internet or TV, which means there’s no “digital babysitter” and he has to rely on his own creative ways to bond with his daughter. Since he received the series, the main thing that has occupied them these days is reading books together.
Burke admits that he thought he was “too cool” for the books when they first came out and he was in his twenties, but he’s loving reading them now. “We switch off chapter by chapter reading them out loud，“Burke explains.” This not only allows her to get more used to reading aloud in front of someone, but it gets me directly involved in something she loves, and it gives me the chance to be very dramatic when I read my chapters and bring myself into the characters in the book, which has proven to be a ton of fun.”
After hearing Burke’s story, Rowling said how honored she was when Harry Potter was a part of his family’s life and offered Burke more books. Besides, people are also offering to send Burke more books as gifts. For Burke, this experience, far more than gifts, will be what he treasures.

3 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.
Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.
There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”
Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.
A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.

4 . Dorothea Dix was born in 1802 in Massachusetts. When she was 12 years old, she left her unhappy home to live with her grandmother in Boston. There Dorothea went to school and was so quick at her lessons that two years later she went back to Worcester, Massachusetts and taught in a school for little children. She was only fourteen and rather small for her age. Anyway, she proved herself a good teacher, and the children loved her and respected her. In 1821, she opened a school for girls in Boston.
Gradually, her health broke down, and she began to think that she could never work any more, but after a long rest in England, she came back to America and did something far greater than teaching. She went through the whole country where she first observed the inhumane treatment of the mentally ill. During Dorothea’s traveling for nearly two years throughout the state, and meeting similar conditions, she always spoke kindly to the ill-treated, but she spoke wrathfully to the men who ill-treated them. In January 1843, she submitted to the Massachusetts legislature (立法机关) a detailed report of her fully documented findings.
In the next 40 years Dorothea inspired legislators in 15 US states and in Canada to establish state hospitals for the mentally ill. Her continuous efforts directly affected the building of 32 institutions in the United States. When the Civil War broke out, she went straight to Washington and offered to nurse the soldiers without pay. She hired houses to keep supplies in and bought an ambulance. She gave her time, strength and money to her country.
Dorothea Dix has been called the most useful woman of America. She is an, American educator, social reformer and humanitarian whose devotion to the welfare of the mentally ill led to widespread reforms in the United States and abroad.

5 . Would you take a trip if you couldn’t use your cellphone? A new tour company called Off the Grid is asking travellers to put their cellphones away and not even use them for photos. The company founder, Zach Beattie, is developing his business, using money he saved from a tech job at a mapping company. He’s hired guides for every trip but will help lead the first few himself.
The first trip is to Lisbon, Portugal, in July. It takes 7 to 10 days, with small groups of up to 16 people. Prices range from $1,500 to $1,650, including accommodations, meals and ground transportation. The plan includes at least three excursions (远足) and two social events, with an emphasis on unique experiences over bucket-list sightseeing. The tour also includes surfing lessons, yoga on the beach, a day of sailing and dinner with a local family.
“When you’re somewhere new, there’s a lot to see and a lot of cool and interesting people to meet,” Beattie said. “Your phone can distract (使分心) you.” The phone ban won’t be enforced quite as strictly as it seems at first glance. “We want it to be voluntary,” he said. “We’re not collecting phones and throwing them in a locked trunk. It’s held by you, but put in your pocket, and you state your intentions for the week, whether that’s checking your social media once or twice a day or a total blackout.”
Tour-goers also get a “dumbphone” without Internet access that’s loaded with numbers for group leaders and other participants, both for emergencies and to promote socializing. Participants may bring regular cameras, but Beattie is hiring a photographer for each tour so there will be plenty of photos to remember the trip. Once the trip is over, participants will have access to those photos for use in social media posts.

6 . In today’s digital era, social media users are increasingly coming across fake news online. This leads to the pressing issue: What causes people to fall for misinformation on the Internet?
According to researchers at the Penn State College of Information Sciences and Technology, users can easily fall into an echo chamber (回声室)—a sort of virtual space where users consume only one-sided news, eventually distrusting any opposing views. “We all tend to agree with the group opinion. Hence, people naturally get together with others who hold the same opinion,” said Dongwon Lee, one of the researchers. “But if you’re not cautious, there is a high risk of falling into an echo chamber.”
To prevent this phenomenon, the researchers have crafted a novel tool, a game named ChamberBreaker, to help players resist echo chambers and reduce the rate of fake news spread. The fundamental approach employed by ChamberBreaker centers around a decision-making procedure that mirrors the creation of echo chambers. In ChamberBreaker, a player is tasked with trying to have community members fall into an echo chamber. To begin, the player is randomly assigned a situation that focuses on a health, political or environmental issue, and is presented with six pieces of news on that topic. Then, the player selects news that could cause the other members to fall into an echo chamber while at the same time maintaining their trust. If successful, the community members will fall into an echo chamber and the player will witness the resulting negative effects on the community.
After developing ChamberBreaker, researchers tested it with over 800 subjects to see if it raised awareness of echo chambers and changed news consumption behaviors. The researchers found that those who played ChamberBreaker were significantly more likely to state their intention to observe online information from more diverse perspectives and showed an increased awareness of the echo chamber phenomenon.
Ultimately, the researchers hope that their methodology can excite a greater interest in the scientific and scholarly study related to information consumption. The application of tools like ChamberBreaker, which focuses on fostering analytical reasoning, may lead us towards a more informed online community.

7 . This question has fascinated behavioural scientists for decades: why do we give money to charity?
The explanations for charitable giving fall into three broad categories, from the purely altruisic (利他的)— I donate because I value the social good done by the charity. The “impurely” altruistic— I donate because I extract value from knowing I contribute to the social good for the charity. And the not-at-all altruistic— I donate because I want to show off to potential mates how rich I am.
But are these motives strong enough to enable people to donate as much as they would want to? Most people support charities in one way or another, but often we struggle to make donations as often as we think we should. Although many people would like to leave a gift to charity in their will, they forget about it when the time comes.
Many people are also aware that they should donate to the causes that have the highest impact, but facts and figures are less attractive than narratives. In a series of experiments, it was found that people are much more responsive to charitable pleas that feature a single, identifiable beneficiary(受益者), than they are to statistical information about the scale of the problem being faced. When it comes to charitable giving, we are often ruled by our hearts and not our heads.
The good news is that charitable giving is contagious—seeing others give makes an individual more likely to give and gentle encouragement from an important person in your life can also make a big difference to your donation decisions— more than quadrupling them in our recent study. Habit also plays a part— in three recent experiments those who volunteered before were more likely to do donate their time than those who had not volunteered before.
In summary, behavioural science identifies a range of factors that influence our donations, and can help us to keep giving in the longer term. This is great news not just for charities, but also for donors.

8 . Manta rays (魔鬼鱼) are some of the creatures in the ocean who allow divers to swim right up to and interact (与……互动) with them. Unfortunately, these gentle animals are in big trouble. Since 2011, manta rays have been listed as a threatened species worldwide.
Peru, a country in South America, recently took a big step to protect giant manta rays: It banned fishing for them. Although 12 other countries have passed laws to protect rays, Peru’s may be the most important one yet. That’s because there are more manta rays in the Pacific Ocean near Peru than in any other place in the world.
Giant manta rays are unusual-looking creatures. The giant, flat rays are typically about 4. 5 meters wide and can grow up to 8 meters wide! “They’re sort of like giant flying carpets underwater, ” says Joshua Stewart of the Manta Trust, an organization that researches manta rays.
People catch rays for their meat. Overfishing is bad for any sea creature, but it’s even worse for manta rays. Female manta rays usually have only one baby, every two to five years. So every ray that’s caught hurts the population in a big way. People who break Peru’s new law can be fined or have their fishing licenses taken away. Even rays caught accidentally in fishing nets must be set free.
Earlier this year, the Manta Trust attached video cameras, called Crittercams, to manta rays off the west coast of Mexico. The footage (连续镜头) the cameras collect could help researchers predict where rays swim and when. The scientists could use the information to warn fishing boats to avoid these areas, helping reduce the number of accidentally caught rays.
Stewart says it’s important to protect these unique creatures. “There’s really no other animal that compares in size that you can have interactions with in the wild.”

9 . Soap (肥皂) might seem like a reasonable way to avoid mosquito bites (蚊子叮) on the basis that if mosquitoes can’t smell you, they can’t bite you. However, a recent study has found that rather than protecting you, certain soaps might actually make you more attractive to mosquitoes.
In the study, conducted at Virginia Polytechnic Institute and State University, four volunteers were asked to wear a sleeve before and after washing with four different brands of soap. The researchers then watched female mosquitoes as only females feed on blood landing on the fabric sample to show their preference. They found that some people washing with some brands of soap, increased their attractiveness to mosquitoes, while washing with other brands of soap tended to repel (驱除) mosquitoes. The repellent effect of some soap may be due to its coconut scent, as coconut oil is known to act as a natural mosquito repellent. The reason behind this attraction is believed to be related to mosquitoes’ sugar intake. When mosquitoes are not feeding on blood, they add their diet with plant juice or sweet water from flowers, “The fact we are taking those flowery and fruity smells and putting them on our bodies means that now the same object smells like a flower and a person at the same time,” said Clément Vinauger, who led the study. It would be like waking up and smelling the smell of coffee and bread, very attractive.
Interestingly, the effects of the soap varied among people, possibly due to the interaction (相互作用) between the soap and each person’s unique body scent. “It’s remarkable that the same person that is extremely attractive to mosquitoes when he is unwashed, but he becomes even more attractive to mosquitoes with one soap, and then become repellent to mosquitoes with another soap,” said Vinauger. Further research is needed to better understand the interaction between different soap and body scents, as well as to develop more effective mosquito repellents.

10 . The design theory behind a pair of tiny robots may one day find its way into environmental monitoring, as well as search and-rescue tasks. Modeled after a water strider (水黾), an insect, the two robots each weigh in at 8 and 55 milligrams, and may mark the smallest, lightest, and fastest fully functional micro-robots in the world, according to Washington State University (WSU).
Developed by a team of WSU researchers, the robots’ tininess largely relies on a material known as a shape memory alloy (合金). Although shape memory alloys change form when heated, they can “remember” their original shapes and return to them after cooling. Because of this, the two micro-robots do not require standard motors, and they use light and small ones instead of bulky moving parts.
Both the robots’ motors are each made up of two shape memory alloys, allowing them to move their fins as fast as 40 times a second while also lifting over 150 times their weight. “They’re very technologically sound. The development of the very lightweight robots opens up new possibilities in micro-robotics,” said Conor Trygstad, a material engineering PhD student and study lead author. “Although the robots are impressive when compared to other robots, the pair still fall behind their biological relatives’,” Trygstad said. They can currently move at a speed of about six millimeters a second; a water strider, by comparison, speeds along at about a meter per second. For now, the robots also require wired (连线的) power sources, thus seriously preventing any real-world applications for the moment.
Going forward, however, the team plans to copy other small insect species while also creating a new water strider robot which can move at a higher speed. Depending on using small batteries could also greatly increase the robots’ areas of use, If the breakthrough designs continue improving, similar micro-robots could one day be employed to monitor hard-to-reachor dangerous environments.
