1 . It has long been believed that the smart phones in our pockets are actually making us dumb (迟钝的). Now there is evidence for it.
Researchers at the University of Texas at Austin discovered that people are worse at completing tasks and remembering information if a smart phone is within sight. In two experiments they found phones sitting on a desk or even in a pocket or a handbag would distract (使分心) users and lead to worse test scores even when they were set up not to disturb test subjects.
The researchers tested 520 university students on their memory and intelligence when they were in the presence of a smart phone to see how it affected them. They were told to complete tests in mathematics, memory and reasoning with their smart phones either on their desks, in their bags or pockets, or in another room. Those who had their phones on the desk recorded a 10 percent lower score than those who left them in a different room. Those who kept their phones further out of sight in their pockets or their bags scored only slightly better than those whose phones were placed on desks.
The researchers found that the negative effect of having a phone within sight was greater among those who said they were dependent on their smart phones. It was also found that phones could distract users even when they were turned off or when they were placed face down.
The researchers said the effect arises because part of the smart phone users’ mind is trying not to think about distractions such as whether they have any messages when the smart phone is in their line of sight.
Similar research has previously shown that smart phones can lead a “butterfly brain effect” on users that can cause mental blunders (错误).

2 . I started a Facebook page in July, and it’s steadily growing! The best part isn’t the number of its “followers” but its comments — I love reading about what people do, their ideas and views and get some feedback (反馈) on what I’m doing too.
In April of this year, I was invited by a friend to join her Social Change group. We were eight women from all walks of life, but we had one thing in common — we live in a fantastic country and yet we can see homeless people on the streets asking for money. We have a generous welfare system and a social housing scheme — but it’s a problem that is getting worse. We asked ourselves: What happens to homeless women?
Therefore, we volunteered at shelters. We met with social housing providers, shelter managers and social workers, and began to think what else we could do. We researched on which programs were having success. We had guest speakers at our meetings and began to get a clear picture about what we needed to do.
As luck would have it, we have been gifted a building in the city center. It’s old and needs a lot of work to bring it up to the standard. We want to provide more than just shelter to women in need. We aim to have six self-contained apartments providing full social services for women to stay in for up to two years. Thanks to the building provider, we have got our project off the ground.
I’m an ordinary person. If I can do this, anyone can. You can change the world. Look for the opportunity and just do it.

3 . The days of the bedroom fitting room are numbered. Online retail giant (零售巨头) Boohoo has become the latest in a string of retailers to start charging shoppers for returns.
By offering free returns in the first place, companies, such as Boohoo, created entirely new behaviour around shopping. A 2018 study found that 9% of UK consumers buy clothes to post on social media, only to return them straight after. Almost one in five 35-to 44-year-olds admit to doing it, and men, apparently, do it more than women.
However, when clothes are returned, they’re likely to be thrown away rather than resold. This is because processing returns is time-consuming and costly. Buttons need to be rebuttoned, labels need to be reattached, products need refolding and rebagging, and then they must be put back into the system for sale. So it is clearly a cheaper and easier solution for businesses to send the whole lot to landfills (垃圾填埋场). It’s really a great waste of resources, not to mention an insult (冒 犯) to the skilled people who put their time into making each product, but it’s the reality of modern fashion.
When clothes don’t become rubbish, there’s still the impact of the extra shipping to consider, as well as the packaging waste. About 180bn plastic bags are produced every year to store, protect and transport clothes, and less than 15% of them are collected for recycling.
The impact of returns is a fairly well-kept secret, likely to keep people shopping guilt-free (没有负罪感地). But even if it was widely known, it wouldn’t guarantee people would stop treating returns thoughtlessly. After all, other environmental and human impacts of fast fashion are out there for all to see and yet the industry continues to thrive.
Hopefully, charging for returns is expected to change people’s behavior. Without free returns on the table, shoppers may think twice about buying 10 items when they know they’ll only keep five or buying clothes purely for social media content. And with the arrival of return charges, the clothes we already have might also start to look a little more appealing.

In order to make young people realize the
5 . Every morning in a city in Indonesia’s far east, sleepy teenagers can be seen walk slowly and with heavy steps through the streets on their unwilling way to school.
It is not a scene from some sci-fi movie but a controversial experiment to get the day off to a much earlier start for the sleep-deprived (缺乏睡眠的) teens. The pilot project in Kupang has twelfth-graders at 10 high schools start classes at 5:30 am.
Authorities say the project is intended to heighten children’s discipline. According to parents, though, their children are worn out by the time they get home. Schools in Indonesia generally start between 7:00 and 8:00 am. Teens in their school uniforms are now walking down dark streets or waiting for motorcycle taxis to get to school on time.
“It is extremely difficult and they now have to leave home while it’s still completely dark. I can’t accept this, for their safety is not guaranteed when it’s dark and quiet.” Rambu Ata, a mother to a 16-year-old, said, whose daughter Eureka now has to wake up at 4:00 am to get ready and ride a motorbike to school. “Now every time Eurek arrives home she is exhausted and falls asleep immediately.”
At least one scholar seems to agree.
“It has no connection with the effort to improve the quality of education,” Marsel Robot, an education expert from Nusa Cendana University. “In the long run, sleep deprivation could endanger the students’ health and cause a shift in behaviour. They will only sleep for a few hours and this is a serious risk for their health. This also will cause them stress and they will release their stress by acting out.”
A 2014 study published by the American Academy of paediatrics (儿科学) recommended that middle and high schoolers start classes at 8:30 am or later to allow enough time for sleep. The Kupang rule change was also challenged by local politicians, who demanded the government cancel what they called a baseless policy.

7 . A new study finds that less than seven percent of the adult population in the US have what health experts consider good cardiometabolic (心脏代谢) health.
Using information on roughly 55,000 people over the age of 20, the results show just 6.8 percent of American adults reached optimal (最佳的) levels of health in 2018. Moreover, the study found American health has been in sharp decline over the last 20 years. In 1999, one in three adults had a healthy weight. By 2018, that number fell to just one in four Americans. At the same time, three in five people were free of diabetes in 1999. By 2018, however, more than six in ten adults had the condition!
“These numbers are striking. It’s deeply problematic that in the United States, fewer than 1 in 15 adults have optimal cardiometabolic health,” says Meghan O’Hearn, one of the researchers from Tufts University. “We need a complete overhaul (革新) of our healthcare system, food system, and living conditions, because this is a crisis for everyone.”
Instead of just looking for signs of disease, the team focused their study on the signs of good, moderate, and poor cardiometabolic health. “Disease is not the only problem,” O’Hearn explains. “We don’t just want to be free of disease. We want to achieve optimal health and well-being.”
Researchers also found large health gaps between US adults of different genders, ages, and education levels. Specifically, the study found Americans with less education were half as likely to be in peak cardiometabolic health.
O’Hearn adds, “Identifying these individuals and addressing their health conditions and lifestyle early is critical to reducing growing healthcare burdens. Its impacts on national healthcare spending and the financial health of the entire economy are enormous. And these conditions are largely preventable. We have the public health and clinical interventions and policies to be able to address these problems.”

8 . Schools in US are huge consumers of energy. According to ENERGY STAR, K- 12 schools spend more than $6 billion every year on energy, far more than the amount spent on other resources, and at least 30 percent of this energy is used inefficiently or needlessly.
Realizing that, some schools are seeking measures to save energy in several ways, from low-cost adjustments, such as turning off lights in unused rooms, to large-scale projects, such as turning to green equipment.
As solar energy is becoming a more financial choice for powering buildings, more schools are making the move toward the renewable energy and using solar panels(太阳能电池板)on their rooftops. According to an online solar marketplace EnergySage, schools have their strong points to use solar energy. They often have the kind of enough space, suitable locations that are perfect for setting up solar panels.
In September 2020, a nonprofit Generation180 released its third edition of a study on solar use in US schools. The findings showed that more than 7, 300, or 55 percent, of K- 12 public and private schools used solar energy, the number has increased by 81 percent since 2014.
They also described how solar schools were saving millions in energy bills, and provided several cases to show the increased savings achieved by solar-powered school districts. For ex- ample, an Arkansas school district used its every year's energy savings of nearly $100, 000 to increase its teachers' salaries.
The Interstate Renewable Energy Council, which tracks the number of K- 12 schools with solar equipment and helps schools go solar, says on its website that schools with solar setups have an opportunity to educate students about clean energy, and show them that they are de- voted to do something for students' and the planet's health and future.
Third-party ownership also makes funding for 79 percent of schools to use solar energy possible, meaning a majority of schools don't have to spend large amounts of money but can get the rewards of solar energy.
