1 . Packaging can play a greater role in keeping produce and other foods fresh, therefore minimizing food waste — especially if consumers can better understand those packaging technologies. That’s among the takeaways of research led by Michigan State University (MSU)’s School of Packaging, detailed in a recently released white paper.
In the United States, food waste in landfills doubled from 1990 to 2020, according to data shared by the US Environmental Protection Agency this year. Researchers cited data showing 40% of the food supply is wasted each year, with 43% of that happening at the consumer or household level.
Ameripen, the only organization exclusively focused on US public policy for the entire packaging industry, and the Environmental Research & Education Foundation funded research that included a survey of more than 1,000 people in the United States. Ameripen said it wanted to know what role packaging could play in reducing household food waste as well as understand consumer awareness of food packaging’s value and functions.
The survey asked consumers about their understanding of packaging forms and willingness to pay more for packaging designed to reduce food waste, among other areas.
The study found that whole fruits and vegetables, particularly bananas and lettuce, are the foods most wasted by households, with dairy products, prepared packaged foods and leftovers also common culprits (罪魁祸首). “Half-eaten packaged food products and food without packaging that went bad before it was eaten are the two primary reasons for food waste in American households, indicating there is opportunity for improved packaging design to help consumers with extending shelf life, reuse and size,” the white paper states.
Researchers reported that while consumers’ current understanding of packaging technologies was “limited”, they indicated “they would pay more for food contained in packaging that extends freshness and shelf life.”
“There’s a need to design packaging for produce that is currently not packaged; that most of the produce in this study was wasted is because there is no packaging at all,” MSU’s Korey Fennel said during the webinar (网络研讨会), also noting the importance of “intelligent packaging” that could indicate the shelf life of food products.

2 . Estefanía Rebellón was once a migrant (流动的) child. She was 10 when her family fled Cali, Colombia, because of death threats to her father, who had been forced into hiding. They settled in Miami. Despite the challenges she faced as a migrant child, she was lucky to have teachers who advocated for her and guided her along the way.
Rebellón moved from Miami to Los Angeles when she was 21 to pursue an acting career. In 2018, she was so moved after volunteering in migrant camps in Tijuana that she put her career on hold. “There were no schools set up to help these kids. They were walking around the camps barefoot,” she said.
Rebellón and her partner Kyle Schmidt used about $1,000 of their savings to buy tents and supplies and set up a makeshift (临时的) school at the border. They enlisted volunteer teachers to provide learning opportunities in the camps. In the months that followed, when those families living in the camps were moved to shelters, Rebellón and Schmidt wanted to continue offering educational services.
“I thought, ‘Why don’t we turn a bus into a mobile classroom, and we could take it to all the different shelters?’” Rebellón said. Over the next year, Rebellón and Schmidt bought and transformed a bus, partnered with shelters, and drove the bus over the border.
In 2019, she co-founded the Yes We Can World Foundation, a nonprofit organization that believes every child has the right to education and safe spaces regardless of their location, current legal status or economic background.
Rebellón’s organization hires professional teachers and tailors their curriculum (课程) to the specific needs of each student. “The program has been officially approved by the education secretary in Mexico and serves children aged 3 to 15 — a crucial period for education,” Rebellón said.
Today, the Yes We Can World Foundation educates 250 — 300 kids a day through its four school locations along the border and three mobile school buses. “Since 2019, the group has served more than 3,100 migrant children from 10 countries,” Rebellón said.

3 . On one side of the room sits the cutest life-size stuffed animal (填充玩具) you’ve ever seen. On the other side rests a real dog — the same size, shape and even the same name as the stuffed version. You get to sit next to both of these furry friends and pet their fur. Guess which one will make your brain light up?
If you guessed the real dog, you’re right. Stuffed animals, as cute and lovely as they may be, just don’t effectively activate our frontal cortex (额叶皮层), the part of the brain overseeing how we think and feel, according to a new study published in the journal PLOSONE. The study found an even stronger rise in brain activity when the person petted the fur of a real dog versus a stuffed animal.
“We chose to research the frontal cortex because this brain area is involved in several executive (执行) functions, such as attention, working memory, and problem-solving. But it is also involved in social and emotional processes,” said study lead author Rahel Marti, a doctoral student in the division of clinical psychology at the University of Basel in Switzerland.
Why is this finding important? It provides additional evidence that live human-animal interaction therapy (疗法) may promote cognitive and emotional activity in the brain. Marti said, “If patients with deficits in motivation, attention, and socioemotional functioning show higher emotional involvement in activities connected to a real dog, then such activities could increase the chance of learning and of achieving treatment aims.”
“This is an interesting, seriously conducted study that provides new insight into associations between human-animal interaction and regional prefrontal brain activity in healthy adults. We found that brain activity increased when the contact with a real dog or a stuffed animal became closer. This confirms previous studies relating closer contact with animals to increased brain activity,” Marti said.

4 . “Oh no, Haley. Why are you crying?” A question we often hear when we’re chopping onions.
Well, it all starts underground. Life for an onion is pretty sweet when they’re down there in the dirt. Except when bugs (虫子) come by wanting a bite. Onions don’t like that at all.
This chemical is called syn-propanethial-S-oxide, which is what causes the tears when we cut into them. When we slice into onions to cook them,

5 . Ants have the ability to smell cancerous cells in humans, a new study has discovered, suggesting they could be used for cancer diagnosis in future. Researchers from the French National Centre for Scientific Research (CNRS) discovered that ant species Formica fusca has a well developed sense of smell. It was able to differentiate (区分) cancerous cells from healthy cells in humans, thanks to their sense of smell, limited trials revealed.
To conduct their research, the scientists performed tests with 36 ants, smelling cells under a laboratory setting. First, the specialists exposed the ants to the smell of a sample of cancerous human cells. This smell was then associated with a reward of sugar solution. In a second step, the researchers exposed the ants to two different smells. One was a new smell and the second was the smell of the cancerous cells. Once this test was successful, the researchers exposed the ants to different cancerous cells.
As such, the scientists found that ants discriminate between cancerous and healthy cells and between two cancerous lines. After training, Formica fusca ants are able to detect volatile organic compounds given off by cancerous cells. This first study shows that ants have high potential, are capable of learning very quickly, at lower cost, and are efficient, CNRS points out in a news release.
This isn’t the first time that scientists have used the animal sense of smell to locate cancerous cells. “Dogs’ noses are well suited for medical diagnosis. However, training them to do so requires several months to a year. Ants therefore represent a fast, efficient, inexpensive, and highly discriminant detection tool for detection of cancer cell volatiles,” the team explained, “our approach could potentially be adapted to a range of other complex smell detection tasks including the detection of narcotics, explosives, spoiled food, or other diseases.”
But more clinical tests must be carried out before they could be used in clinical settings like hospitals, the team said. They suggest that in future, ants could turn out to be better than dogs when it comes to locating cancerous cells in humans. Who knows? Let’s wait and see.

6 . South Korea’s birth rate, already the world’s lowest, has dropped yet again in the latest setback to the country’s efforts to boost its declining population.
The national statistics body reported Wednesday that the birth rate fell to 0.72 in 2023—down from 0.78 the previous year. Countries need a birth rate of 2.1 to maintain a stable (稳定的) population, in the absence of immigration. South Korea’s birth rate has been falling since 2015 and the country recorded more deaths than births for the first time in 2020, a trend that has continued since. In 2022, the country recorded about 249, 000 births and 372,800 deaths. Meanwhile, Korean women are also having children later in life. The average age of childbirth in South Korea was 33.5 last year.
Similar population declines are being seen in several other Asian countries including Japan and China, raising concern that there will be too few people of working age to support the ballooning elderly population.
Experts say the reasons for these population shifts across the region include demanding work cultures, stagnating wages, rising costs of living, changing attitudes toward marriage and gender equality, and rising disappointment among younger generations.
But despite the economic factors at play, throwing money at the problem has proved ineffective. Last September, South Korean President Yoon Suk Yeol admitted that more than $200 billion has been spent trying to boost the population over the past 16 years. The South Korean government has introduced various initiatives such as extending paid paternity leave, offering monetary “baby vouchers” to new parents, and social campaigns encouraging men to contribute to childcare and housework. But experts and residents say more support is needed throughout a child’s life, as well as change on several deep-rooted social issues.

7 . A swimming pool is a wonderful addition to a home that the whole family is sure to enjoy! The luxury of being able to slip into a nice, cool pool on a hot summer day in the privacy of one’s backyard is well worth the cost! The swimming pool is a lot of fun, but it also presents some hazard! The following is a list of things you can do to make sure your family is protected and your pool is a safe space to enjoy!
Learn To Swim — Being unable to swim makes you an accident waiting to happen, be it at the pool, the beach, or around any body of water! Our advice for guests is to have all visiting children have a basic swimming test at the shallow end to judge their skills — if they don’t pass, then the deep end is strictly off limits to them, even with floatation (漂浮) aids since they can be dangerously unreliable!
Children Supervised — Any children under the age of ten should be actively supervised by a responsible and vigilant adult who knows how to swim! Children should always be kept in sight, and children under the age of five should always be within easy arm’s reach.
Sun Protection — The water is not the only potential hazard in a swimming pool, exposure to harmful UV rays can be compounded as they reflect off the water’s surface, and if no measures are taken can deliver a nasty sunburn that may even require a doctor’s care! Apply waterproof sunscreen to all exposed parts of the body. Don’t use water-resistant products, they don’t resist for very long, and can just make matters worse!
Swimming pools are a lot of fun, but it’s up to you to play it safe!
1. Why are swimming tests recommended for visiting children?| A．To ensure them to swim safe. | B．To help them learn to swim faster. |
| C．To make sure they enjoy swimming. | D．To keep them away from the deep end. |
| A．To stay indoors during the day. | B．To apply waterproof sunscreen. |
| C．To use water-resistant gloves. | D．To wear dark-colored swimming suits. |
| A．In a travel brochure. | B．In a school document. |

8 . Grammy Awards don’t only go to the people who produce and perform songs. For just over a decade, they’ve also been given out to those who teach others how to make music. The Music Educator Award, presented by the Recording Academy and Grammy Museum, recognizes those who have made a “significant contribution and demonstrate devotion to music education”.
This year it went to Annie Ray, the performing arts department chair and orchestra director at Annandale High School in Fairfax County, Virginia. She was honored for her efforts to make music accessible to all students, particularly those with disabilities. Ray got to attend the awards ceremony in Los Angeles, take selfies with pop stars and bring home both a $10,000 prize and matching grant for her school’s music program.
Ray created the Crescendo Orchestra (管弦乐队) for students with severe intellectual and developmental disabilities, as well as a parent orchestra that teaches nearly 200 caregivers a year to play the same instrument as their child.
She was inspired in large part by the diversity of the Annandale community, which she says represents over 60 countries, including many immigrants. “There’s a. lot of cultures that might typically clash, and they come together in this very beautiful harmony,” Ray explained. “And that’s really uniquely expressed in the orchestra classroom, where we’re just all music-ing together.”
Ray says the Crescendo Orchestra, which was born out of the pandemic, doesn’t necessarily share the social goals of a program like the Special Olympics. The focus is on teaching students how to play an instrument, through one-on-one instruction tailored to their needs. That involves tools like music scarves, egg shakers, rhythm sticks and cardboard instruments. Ray also works with a local charity to give damaged instruments a second life in her classroom.
The orchestra is about much more than just making music, however. Ray says the program gives students a chance to develop their collaboration skills, make mistakes and learn the art of refining something.
1. Which of the following is the reason for Annie Ray’s winning a Grammy?| A．Her determined effort to make music. | B．Her contribution to the high school. |
| C．Her commitment to music education. | D．Her excellence in performing songs. |
| A．Her enthusiasm for instructing music. | B．The diverse cultures of the community. |
| C．Her burning desire to win a Grammy. | D．The severe disabilities of her students. |
| A．To fix damaged instruments for a local charity. |
| B．To help students to face the pandemic bravely. |
| C．To make students familiar with music devices. |
| D．To give students need-centred music teaching. |
| A．A music teacher won a Grammy | B．A music teacher changed lives |

9 . On a chilly autumn morning in the Italian countryside near Larderello, Tuscany, the misty landscape reminded me why the area is nicknamed the Devil’s Valley. The land here is a web of natural cracks in the rock that let a mix of steam and gases reach the surface.
Unlike the rolling hills and cypress-lined roads of other parts of Tuscany, the landscape here is covered with dozens of grey cooling towers puffing white vapors. The deafening roar of a turbine (涡轮机) at the Valle Secolo geothermal (地热的) plant breaks the quietness, but its violent spinning transforms steam rising from underground into energy for 150,000 families in the region. About 30% of Tuscany’s electricity comes from this energy source. After producing electricity, the leftover steam heats water for nearby districts.
This underground energy has recently proved a vital resource. Italy greatly depended on Russian fossil fuels and in 2023 Italians bore the world’s highest household electricity bills. Factories cut down production and households had to turn down their heaters. But residents of the Larderello area spent the winter in warm homes, thanks to the local geothermal plants working 24/7.
Bruno Della Vedova, president of the Italian Geothermal Union, hopes that in the future other Italian regions could benefit from such a resource, which is extremely important when the whole world looks to transition to renewable energy.
While countries like Iceland and Kenya are taking advantage of their geothermal resources, the industry’s growth has made slow progress in Italy. High set-up costs and difficulties in extraction present significant barriers. And new plants often run into opposition from nearby communities over health concerns.
Italy sits on a geothermal sweet spot. Especially below Larderello, as Della Vedova says. A vast reservoir (储备) of steam and water is trapped between Earth’s inner heat and a layer of clay-heavy rocks. High temperatures lead to the formation of steam directly inside the reservoir, providing a significant source of energy.
But while heat from Earth’s core is practically endless, the water it heats within the planet are not. So Della Vedova says restoring underground water supplies and using them sustainably is critical for the future. “We can’t take advantage of a geothermal resource at will,” he says.
