1 . Which is more important for parents, making more money to give the kids a better life or spending more time with them? It is a problem for parents and it is not easy to decide. A new study shows that today’s parents are spending more time with their children than parents in the past. According to the study, today’s college-educated mothers spend about 21.2 hours a week taking care of their children. But women with less education spend about 15.9 hours. Before 1995, it was only 12 hours.

Dads are spending more time on ball games. Before 1995, fathers with college educations only spent about 4.5 hours a week playing with their children. Today, it increases to 9.6 hours a week. For fathers with high school education, the time goes up from 3.7 hours to 6.8.

These days, parents don’t care more about the cleaning or the cooking. They are trying their best to spend time with their families. As for the kids, they don’t mind how much time their parents spend with them. They just want to enjoy the time their parents do be with them.

So, take part in the kids’ activities when you are with them, such as helping with homework or playing soccer with them.

2 . With over 70% of the country blanketed in forest, Bhutan is rich in outdoor activities and charming villages that showcase a distinctive culture found nowhere else on the Earth. Here are our picks for the best places to add to your Bhutan traveling list.

Paro

Less than 10 minutes away from the airport, the historic riverside town of Paro is known for the National Museum, Rinpung Dzong and symbolic Tiger’s Nest Monastery. Wander along Paro’s streets and the Paro Weekend Market to explore shops and stands offering handmade souvenirs. When you’ve worked up an appetite, step into any restaurant for fresh, handmade momo dumplings.

Thimphu

In Bhutan’s capital city, spend the day creating your own stamps at the Bhutan Postal Museum, touring the massive Thimphu’s museums and watching policemen manually direct traffic(there are no traffic lights in the entire city). When the sun sets below the mountains, enjoy yourself at bars like Grey Area, a popular art bar with live music where you can shout “tashi delek!”, a Xizang’s expression for good luck and health.

Punakha

Beloved for riverside farms where cows eat among rice and pepper fields, Punakha is home to what is its most beautiful temple, which sits along the Punakha River. Punakha’s low altitude means it tends to be hotter and sunnier than nearby towns and districts, which means you’ll need to take precautions to avoid sunburn.

Khoma

Fashion lovers can expect to visit behind the curtain in Bhutan’s textile center, Khoma. In the eastern district of Lhuentse, this village is home to roughly 1,000 residents—and few cars.

3 . 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.

5 . As a saying goes, you’re only as old as you feel, but what if different parts of your body aged at different speeds? It turns out they do. The study about the age of our bodies shows that different tissues inside us are effectively different ages. In 2012, Professor Steve Horvath at the University of California, Los Angeles, looked at something new—DNA methylation (甲基化), a naturally occurring process in which DNA is chemically changed over time.

Horvath analyzed the DNA in 8,000 tissue samples from different parts of the body in different people to study these markers. What he found was striking—the amount of methylation in cells from most parts of the body was a good predictor of the person’s age. But there were inconsistencies. Breast tissue, for instance, ages rapidly, whereas muscle ages slowly. The rates of ageing are also different in men and women. “There are many medical implications, from cancer to premature ageing diseases,” says Horvath. It has already been established that tissue that looks significantly older could be cancerous. Horvath’s study found that cancerous tissue has a biological age on average 36 years older than a subject’s actual age.

Could this knowledge help us live longer? “If the markers relate to a process that causes ageing, then it would be theoretically possible to slow down ageing by carefully targeting DNA methylation,” says Horvath. But before scientists got to work on dealing with methylation, they first needed to establish whether these changes were the cause of ageing or just a byproduct of another process. Now, a 2023 study from the University of Michigan has backed up Professor Horvath’s findings, which means they can safely make further studies of methylation.

“Our main aim was to see whether biological age acceleration measured from DNA methylation was predictive of health outcomes and death,” said research associate professor Jessica Faul. “It turned out that it is largely the case. You can use certain DNA methylation markers to predict age and age-related outcomes quite well.”

6 . Can you name a famous elephant? Babar, perhaps? Or Dumbo? Though these names may be memorable to humans, they sound nothing like the names elephants give each other. “If you’re an elephant, your name is something more like a low, rumbling sound (隆隆的声音),” scientists say. Researchers have found that African elephants emit sounds in response to individuals in their social group, and the receivers respond accordingly.

Researchers recorded 527 elephant calls in northern Kenya and 98 calls in southern Kenya. They then distinguished which members were separated from the herd at the time of each call, or which members were close to the herd. Researchers correctly identified the receivers of 20.3% of the 625 recorded calls. This marks a step forward in understanding how these highly intelligent animals communicate.

“There’s a contact rumble, an anti-predator rumble and a greeting rumble. If you look at a spectrogram (声谱图) with your eyes, they all look almost exactly the same,” said Caitlin O’Connell-Rodwell, an elephant biologist at Harvard Medical School. “That’s why artificial intelligence(AI)has been exciting. It allows us to really figure out what the elephants are saying.”

As it turned out, the calls were distinct to the receivers. Even calls from different callers to the same receiver were similar. The pattern was less obvious than it was between a single caller and his or her receiver. This may be because rumbles encode multiple messages at the same time, so the AI system in computer model may not have been able to pick out the “name” used in each call. “It just highlights the complexity of what’s going on. And we’re not skilled enough in these measurements to figure out what’s going on,” said Caitlin.

However, the research shows how elephants are navigating through a large landscape and can still keep in touch with specific individuals. It allows them to spread out much further and still have very close tabs on individuals, not just the group.

7 . People are always living with technology nowadays. Here comes a smart home, which is controlled by the touch of a button.     1     This acts like a remote control to activate household systems and monitor inside temperatures. If done successfully, a smart home system will be integrated so seamlessly that a household will appear to run itself.

Home automation is designed to introduce efficiency to a home.     2     An efficient smart home uses sensors to prevent over watering of outdoor gardens and control room temperatures, all of which can reduce expenses. In addition to cost savings, home automation often provides a sense of security to homeowners.

Families with children or elderly adults in the home may be reassured by some safeguards in smart home security, like fire alarms that alert the appropriate agencies in the event of a problem. Lighting activation runs on timers, which can be a life saver if an oven is left on when someone leaves the home.     3    

Home automation is not just for safety, however.     4     With a centralized control unit, a person does not have to leave the couch to turn down the blinds or even order groceries, which can be automated.

    5     Such a home becomes dependent on technology for routine tasks. If something goes wrong with the central automation unit, it is not just one appliance at risk as malfunctions can disrupt systems that are vital to running a home. As a result, for all people, a home can become a place of technical faults that repeatedly require repair.

A．A smart home doesn’t apply to all family members.

B．It achieves this by saving homeowners time and money.

C．There are some drawbacks with an automated home system.

D．It can also provide convenience for people living in the home.

E．Home automation depends on furniture and home temperatures.

F．Through home automation, an entire house can be connected via a smart controller.

G．Besides protecting people, it also offers security for expensive items inside a residence.

8 . 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.

10 . For night owls like Chen Danhong, 28, who works for a technology company in Beijing, the day really just begins after about 8 pm, a psychological hint that she can relax. “When I get home, I’m feeling worn out and tired, but that suddenly turns to excitement and I go on the Internet, read novels or watch movies. I’ll be playing video games and continually saying to myself, ‘OK, this is the last one’ before I eventually realize that it’s 2 o’clock,” says Chen.

Common symptoms (症状) include falling asleep later than 2 am, with the average time taken to fall asleep being more than one hour. Young people in cities are most vulnerable to such symptoms, according to the 2020 Chinese National Healthy Sleep White Paper. Common causes are loneliness, overtime sequelae (后遗症), excessive stress and emotional disorders. On March 21, World Sleep Day, a newspaper, Nanguo Morning News, conducted a survey that attracted 2,000 interviewees.

According to the survey, the reasons for going to bed late vary widely, with overtime work or taking care of a baby accounting for just five percent of the interviewees’ answers on this question. Sixty-four percent said they sleep late because they watch dramas, various shows, read books or play with their mobile phones. Fourteen percent said they do not want to go to bed too early even if they have nothing to do.

Many interviewees said they have had experience of the dangers of going to be late. Twenty-three percent said they have no serious physiological problems, but they can feel weak, are easily fatigued and have a poor complexion. Twenty-one percent said they are forgetful and find it hard to concentrate on work. More worrying is that an unwillingness to sleep can lead to a vicious circle (恶性循环), and15 percent of the respondents said they cannot fall asleep even if they want to.
